THEN

From 8.20 "Pac-Man Fever", outside the Bunker, Sam, Dean, Ness, Catty, Young Sabrina and Charlie Bradbury were outside by the Impala, Ness' Car and Charlie's car.

Sam looked at Charlie. "Let us introduce you to the Men of Letters."

From 8.13 "Everybody Hates Hitler", in the Bunker's library, Sam, Dean, Ness, Catty and Young Sabrina saw the Bunker for the first time.

Olivette: (voice over from 10.16 Paint It Black) "It's a rabid group of sanctimonious do-gooders."

From 9.04 "Slumber Party", in the flashback of the Bunker, James Haggerty and Peter Jenkins opened their briefcases, taking out some sort of old fashioned light bulbs. They plugged them into two different boards. All the lights suddenly turned on. There was a wide shot of the whole Bunker.

Dean: (voice over from 8.12 As Time Goes By) "Secret society."

Peter: (voice over from 9.04 Slumber Party) "The last true beacon of light in a world gone topsy-turvy."

From 8.21 "The Great Escapist", in the Bunker's library, Ness grabbed a book, putting it onto the table, pointing to a symbol that looked like a hexagon within a triangle within a circle with three smaller circles on each flat side of the triangle.

Ness: (voice over from 8.13 Everybody Hates Hitler) "European team. They were active during World War II."

From 10.19 "The Werther Project", in the Bunker's library, Sam, Dean and Catty were looking in catalogs. Sam took an envelope from the files, removing an audio tape reel, putting it into the player.

Ness: (voice over from 11.11 Into the Mystic) "Inducted in 1939."

From 11.11 "Into the Mystic", in the Bunker's library, Ness put a large book onto a table, reading the record of a membership that contained a picture of each 'Men of Letters' with their member number, name, date inducted, country of origin, and their duties.

Ness: (voice over from 11.11 Into the Mystic) "Part of a small delegation that was sent to Europe."

From 8.12 "As Time Goes By", in the diner, Sam, Dean, Catty, Ness, Young Sabrina and Henry Winchester sat at their table.

"You're legacies," Henry told them.

From 6.18 "Frontierland", in the Campbell Base's library, Dean, Catty, Sam, Bobby and Ness were sitting at the table.

"Time travel?" Catty asked.

From 6.18 "Frontierland", in Bobby's House, Bobby, Octavia, Castiel, Sam, Dean, Catty and Ness were in the living room. Octavia put two fingers to Sam and Dean's foreheads. Castiel put two fingers to Catty and Ness' foreheads.

From 6.18 "Frontierland", in the past's desert, Sam, Dean, Catty and Ness appeared, looking around.

Catty: (voice over from 6.18 Frontierland) "That's a reasonable plan?"

From 4.03 "In the Beginning", in the motel room, Castiel put two fingers to Catty's forehead.

From 4.03 "In the Beginning", on the street, Catty was lying on a bench at the side of the road, waking up in 1978.

Catty: (voice over from 4.03 In the Beginning) "So, what, Angels got their hands on some DeLoreans?"

From 5.13 "The Song Remains the Same", in the motel room, Catty stood between Sam and Dean, taking either of their hands. Octavia put two fingers on Catty and Dean's foreheads. Castiel put two fingers to Sam and Catty's foreheads. Castiel, Sam, Catty and Dean disappeared.

Catty: (voice over from 4.03 In the Beginning) "How did I get here?"

From 6.18 "Frontierland", in 1861, Catty took the reigns of the horse, whipping them a little, making the horse gallop away. Sam tried to do the same, but it was awkward. The horse he was riding didn't go as fast or as smooth.

From 6.18 "Frontierland", in 1861, in the Deputy's room, he opened the door, aiming a gun at Ness. Ness was aiming a gun at the Deputy.

From 6.18 "Frontierland", in 1861, in the Sheriff's Station, Dean pulled his jacket aside to reveal his Sheriff's badge.

From 8.12 "As Time Goes By", in 1958, the Men of Letters' meeting place, Henry used his blood from the bowl to draw a symbol on the door.

From 8.12 "As Time Goes By", in Dean and Ness' motel room, Henry fell out of the closet, taking in the area around him. 

Sam: (voice over from 8.12 As Time Goes By) "You tapped the power of your soul to get here?"

From 8.12 "As Time Goes By", in the cemetery, Ness, Dean, Sam, Young Sabrina and Catty were standing at Henry's grave.

"Freaking time travel, man," Catty told them.

From 8.13 "Everybody Hates Hitler", in Aaron's House, Sam, Dean, Catty and Ness were posing as FBI. Young Sabrina was sitting next to them.

"The Thule Society," Ness told them. "Right."

From 8.13 "Everybody Hates Hitler", in 1944, in the Nazi's Office, Eckhart lit a match from the candle, throwing the lit match into the bowl of ingredients. Flames erupted. Eckhart disappeared. The flames engulfed the desk and the briefcase.

Ness: (voice over from 8.13 Everybody Hates Hitler) "They were Nazi Necromancers. Dark magic, mostly with dead people."

From 8.13 "Everybody Hates Hitler", in Aaron's House, Sam, Dean, Catty and Ness each shot the Thule men that were aiming the guns at them in the head, making them fall dead. Young Sabrina stepped closer to Eckhart.

Eckhart was on the floor, rolling onto his back, looking up at Young Sabrina. "You fool. You can kill me. But you will never kill all the Thule."

Young Sabrina put a hand to Eckhart's head, smiting him, killing him with a flash of bright white light, making him scream, letting the body fall to the floor. "Well, that's a start."

From 8.13 "Everybody Hates Hitler", in Aaron's House, Ness, Catty and Young Sabrina sat at the table. Sam and Dean stood behind them.

"Nazi bastards," Dean told them.

From 11.10 "The Devil in the Details", in Hell's Limbo, in the cell, there were flashes of the fight with Sam, Dean, Catty, Octavia and Lucifer. Lucifer snapped his fingers. Sam, Dean and Catty started to vomit blood onto the floor, internal organs liquefying. Octavia was desperate to save them.

Lucifer smirked. "Any last words?"

Octavia glared up at Lucifer in hate. "Yes."

There was a blinding flash of light as Lucifer took control.

From 11.10 "The Devil in the Details", in Hell's throne room, Crowley was sitting in his throne. Rowena was standing behind him. Octavia/Lucifer was standing by the door, smirking.

Rowena smiled. "Lucifer."

Crowley looked terrified. "Bloody hell."

Crowley stood to try to flee. Octavia/Lucifer used magic to push Crowley against the floor and the wall. He grabbed Rowena's head, snapping her neck. Crowley flinched.

Octavia/Lucifer let Rowena's body fall to the ground, sighing, walking toward Crowley. "Let's chat."

From 11.12 "Don't You Forget About Me", outside Jody's House, Catty and Castiel were talking.

"Is it a good thing or a bad thing that she's been hanging out with an Angel?" Catty asked. 

"I know Levi," Castiel told her. "He's honorable and kind." They sat on the porch. "You should talk to Sabrina. Let her know that of course you're worried about her, but that you don't want that to stop her from getting the chance to have a friend outside the family."

From 11.12 "Don't You Forget About Me", outside Jody's House, Catty and Sabrina were talking.

"I'm not saying that I trust the guy, because I haven't even met him," Catty told him. "But Cas trusts him. So, I'll give him a chance."

Sabrina smiled a small smile.

From 11.11 "Into the Mystic", in the park in Stuart, Florida, Levi and Sabrina were walking in the park along the trail.

"So, you're starting to worry about your aunt Ava, because you haven't seen her since your family went to Hell," Levi told her.

"Pretty much," Sabrina answered.

"Well, your family doesn't seem to be terribly worried about it," Levi told her. Sabrina pressed her lips together, looking away. Levi nodded understandingly. "It's because they don't know Ava's missing."

From 11.11 "Into the Mystic", in the park in Stuart, Florida, Levi and Sabrina were walking together, walking toward the sunset in the distance.

"If I hear anything, if I see anything, I'll let you know," Levi told her. "And if you need help facing down the Darkness next time, let me know."

From 11.13 "Love Hurts", in the park in Stuart, Florida, Sabrina and Levi were sitting on the bench.

"Sabrina, you gotta tell them," Levi told her. "You need to tell your family. Put them and yourself out of the misery."

From 11.13 "Love Hurts", in the Bunker's library, Castiel and Sabrina were talking.

"I know that you know something's been going on, and I know that you now it's not just with me and Levi," Sabrina told him. "I can't keep quiet anymore. I'm gonna tell you. I'm gonna tell you everything."

From 11.13 "Love Hurts", in the Bunker's library, Catty was sitting in a chair in front of Castiel. "I'm saying that I love you, Cas. And I'm not ready to let you go." She took his hand. "I'm asking you to marry me. Just say yes." She looked at Castiel. "And you and I will finally get all the happiness that we deserve."

Castiel pulled Catty from her seat, closer to him until she was within inches. "Yes." Catty smiled. "Of course my answer's yes."

From 11.13 "Love Hurts", in the Bunker's control room, all of the furniture had been magically moved or magically transported away. Sabrina stood in the middle of the room, turning around, gesturing around. Illusion magics filled the room with beautiful decoration.  The family was dressed in finery.

Ness smiled. "Cas, kiss the girl."

Castiel placed a hand on Catty's cheek, kissing her passionately. Catty wrapped her arm around his neck, deepening the kiss. Amara tossed flower petals over Catty and Castiel excitedly, smiling. The other members of the family cheered. Aiden smiled, waving his little arms. Sam and Dean smiled, clapping. Sabrina smiled excitedly, tilting her head back, content. Ness smiled. Catty and Castiel continued to kiss passionately and endlessly.

Flashback - 1943

Nazi-Occupied France

Night - Gestapo Headquarters

(Song:) Non, Je Ne Regrette Rien - Edith Piaf 

A German Nazi was on the phone, speaking in German. "Es ist angekommen. [It has arrived.] Ja, ich habe eine volle militarische eskorte bestellt. [Yes, I have ordered a full military escort.] Naturlich. [Naturally.] Ich werde das artefakt zu ihnen zu bringen. [I will bring the artifact to you.] Bitte, es ist mir eine grobe ehre. [Please, it is my great honor.]"

The man hung up.

A French woman walked closer, in long, white, satin evening gown. "The bed is cold." The man, speaking a word in German. "What does that mean?"

The man tapped on a very old wooden box. "This is why I've come here."

"And I thought you occupied my country to meet me," the woman told him.

The man smiled. "Mm-mm. You were a bonus, Delphine. A treasure." He spoke in French. "Ma petite collaboratrice. [My little collaborator.] But this? This is what my country has been waiting for."

"Can I see it?" Delphine asked.

The man clicked his tongue. "Naughty, Delphine."

Delphine spoke in French. "S'il vous plait. [Please.]"

The man sighed. "One little peek."

The man led Delphine over to the table.

Delphine opened the box.

The man started to kiss her neck.

Delphine was in shock. "So, it's true." The man continued kissing her neck. Delphine turned to face him, smiling, taking the pin out of her hair, shaking it loose. They leaned closer as if to kiss. Delphine used the hair pin to stab the man in the neck. "I have lived a hard life. But these months, pretending to love a Nazi cochon [pig] like you has been the worst. But this moment, watching you die? It is the best." She pulled the man's knife from its sheath, stabbing him through the heart. The man fell to the floor, dead. Delphine grabbed the box. "The Men of Letters send their regards."

Delphine turned to leave.

Now

Day One

Lebanon, Kansas 

Morning - The Bunker - Catty/Castiel's Room

Castiel and Catty were in bed. 

Castiel had his arm around Catty.

Catty was sleeping. She was slowly starting to wake up. "Cas?"

Castiel smiled a small smile, watching her. "Hello, Catty."

Catty turned in bed to look at him. She smiled, kissing Castiel sweetly but passionately. They pulled away after a moment, looking at each other, smiling.

    §   

Library

Sam, Dean and Ness were sitting at one table.

Ness was researching.

Sabrina, Amara and Aiden were sitting on the floor.

Sabrina and Amara were showing Aiden how to play with some of his toys. "Here, Aiden."

Aiden smiled, clapping.

Sabrina and Amara laughed.

Ness was researching on her laptop, with a few books lying around.

They could hear Catty laughing from the other room.

Ness smiled. "Well, here comes the lovebirds."

Catty and Castiel walked in.

Catty was dressed, looking at the others, smiling. "Hi."

"Someone's cheerful," Sam told her.

"You two finally come up for air?" Dean asked.

"Oh, shut up," Catty told them.

Castiel smiled a small smile.

Sabrina and Amara looked at each other knowingly, smiling.

"Hey, did you now the Nazis had a special branch devoted to archaeology?" Ness asked.

"A little early for Nazi trivia," Sabrina told her.

"It was called, uh, the 'Ahnenerbe'," Ness told them. "There were sites all over Germany." Aiden bounced a small bouncy ball against the floor. Amara caught it. "And then the Nazis increased their territory." Amara rolled the ball back toward Aiden. Aiden used his hands to stop it. "They started popping up in--in Poland, Finland, uh, North Africa. I found something. I mean, we need something. Magic, a--a weapon strong enough to give us a shot against the Darkness. So, I've been looking outside the lore, in history. And I found this. Uh, 'The Vichy Memorandums'. They were Nazi communications that puzzle historians to this day, and they speak of a super weapon obtained by the Ahnenerbe, said to be strong enough to win the war."

"Yeah?" Dean asked. "What was it?"

"Well, uh, these memos refer to it as 'The Hand of God'," Ness answered.

Castiel reacted to the phrase.

Catty noticed. "Cas? You know it?"

"Of course," Castiel answered. "It's sort of a catchall term for several objects He touched, on Earth in Biblical time, but they're believed to contain traces of His power. There were several God-touched objects, but it never occurred to me that any had survived the flood, let alone the 20th century."

"Do you think we can use it against the Darkness?" Ness asked.

"It's perfect," Castiel told them. "I mean, Lucifer's Caged. God's MIA. The only beings strong enough to battle the Darkness before Sabrina are gone. Sow, it took all of your power to exorcise the Darkness from Amara. And it took God and all of his Archangels--Lucifer, Gabriel, Michael, Raphael--just to lock her away. If you're gonna fight her, what better way to arm up than with an actual dose of His power?"

Catty looked at Ness. "Okay, so you said that Nazis got their hands on one of these, uh, 'Hands'."

Catty walked closer, sitting at the other table.

Ness nodded. "Right."

"Well, if it as so powerful it could win them the war, why didn't it?" Dean asked.

"Because they lost it," Ness answered. "En route to Berlin, it was stolen. The Nazis searched high and low for the thief, but they found their prime suspect. Uh, here..." She grabbed a book, handing it to them to show them a picture of Delphine. "Delphine Seydoux. French mistress to a high-ranking Nazi. Thought to be a French traitor till she killed her German lover and made off with the weapon."

"Allied spy?" Sam asked. "French resistance?"

"That's what the Nazis thought, but their investigation led them to a different conclusion," Ness told them. "That she was a 'un Femme de Lettres.'" The others looked at her in confusion. Ness smiled a small smile. "A Woman of Letters."

Catty, Dean, Sam and Castiel were surprised, looking at the picture of Delphine.

    §   

Hell - Throne Room

Octavia/Lucifer was sitting on Crowley's throne, playing Angry Birds on a tablet.

Demons were standing nearby, speaking indistinctly.

A male Demon stepped forward. "Uh, Lucifer? Would you like to hear the latest soul numbers?"

"No, because I don't care," Octavia/Lucifer answered.

"How about an update on the Darkness?" Demon 1 asked. Octavia/Lucifer paused the game, looking up. "Well, the update is... well, that there is no update. We still haven't found her."

A female Demon stepped forward. "If I may... since you've claimed the throne, we could use some direction. Any direction." Octavia/Lucifer sighed, rolling her eyes. "We could deploy a force. Real boots on the ground, shake the trees to find her." Octavia/Lucifer unpaused the game, continuing to play. "W--with you leading the charge, of course. We have had a coward and a fool at the helm for too long." Octavia/Lucifer paused the game, looking up. They could hear muffled groaning. "Perhaps it's time to..."

Octavia/Lucifer held a finger to her lips. "Puppy wants to speak." 

The shot panned to show a cage door off to the side of the chamber. 

A Demon opened the cage door, pulling out a landing with Crowley chained up and in a floral shirt and khaki pants. He took the mussel out of Crowley's mouth.

Crowley sighed. "How dare you? The impudence. The lack of humility. That's no way to talk to your master... Lucifer."

Octavia/Lucifer smirked, tilting her head. "That's a good puppy."

    §   

Lebanon, Kansas

The Bunker - Library

Sam, Dean, Catty, Ness and Castiel researching.

Sabrina and Amara were still keeping Aiden busy.

"Who knew the Men of Letters had European chapters?" Castiel asked.

"Maybe it wasn't an entire chapter," Sam told them. "Just some assets, you know?"

"Yeah, and letting women join way back in the 40's?" Catty asked. "I just never got the impression that they were so big on gender equality. You know, it's right there in the name."

"Well, it was World War II," Ness told them. "Kind of an all-hands-on-deck situation, you know?"

"Yeah, Rosie the Riveter," Dean told them. "Hmm. Cool."

Castiel found a book. "Here we go. This report was written by Clifford Henshaw, a Bunker-based Man of Letters back in 1943. It's the right era." He put the book on one of the tables. Sabrina and Amara stood to look at the book. "But it's in French."

Sabrina looked from the book to Amara in confusion.

Sabrina and Amara looked at the book, tilting their heads curiously.

Dean, Sam and Catty realized who the only one out of the adults that knew French, looking at Ness.

Castiel, Sabrina and Amara looked at Ness.

Ness smiled.

    §   

Later

Dean, Ness and Amara were sitting at one of the tables.

Dean was sitting across from the girls, holding Aiden, bouncing him lightly on his knee. "Aiden, little guy, you're okay."

Ness and Amara were looking at the book, translating it from French to English.

Catty, Castiel and Sabrina were waiting at the other table.

"You know, even if we can't find this Hand of God, there are several out there, scattered around the world," Castiel told them. "We'll never be able to find them on our own."

"I can talk to Levi," Sabrina told them. "He can help us look for more Hands of God. He owes me. Plus, it gives Levi something to do now that he's on the run from Heaven."

"I'm sure that's not the only reason why you wanna go see him," Amara told her.

Sabrina looked at her sarcastically. "Levi's been helping me trying to look for Aunt Ava, Amara."

Amara smirked. "Mm-hmm."

Dean smirked in amusement.

Catty and Castiel exchanged a look, smiling small smiles.

Sam walked in with a beer. "Well?"

"Hey," Ness told them. "So, it's definitely about Delphine. Her name's at the top of every page. Check this out. Transcriptions. From transatlantic cables between Clifford and Delphine."

"What'd they say?" Sam asked.

"They were making arrangements to get the artifact out of Europe to keep it safe," Ness told them. "Uh, Hensaw pulled some strings with a Man of Letters OSS to requisition an active US Submarine to transport Delphine and the weapon back to the States." She looked up at the blank faces of the others. "I lost you again, didn't I?"

"Yeah, baby, a little bit," Dean answered.

"You're supposed to stop me when I do that," Ness told him.

Dean shook his head, smiling. "No way, Nessie. It's way too hot for me to stop you."

Ness tilted her head at him.

Catty smiled.

Sam chuckled. "Mind bottom lining it for us, please?"

"Sure," Amara answered. "They sent the weapon back here."

"Wait, the Bunker?" Sam asked.

"Yeah," Amara answered.

"So, it's been here the whole time?" Catty asked.

"No, no," Amara answered. "Sabrina would've sensed something that powerful by now."

Ness looked up the USS Bluefin. "Amara's right. It never arrived. Uh, the USS Bluefin came under German attack midway through its trip across the Atlantic. The sub was sunk. The ocean was dredged for the ship and its contents, but the Hand of God was nowhere to be found. Great. It's lost."

Sam cleared his throat.

Catty thought for a moment. "Or is it?"

"Well, yeah, I'd say so," Sam answered. He looked at Ness' laptop. "I mean, submersibles have been trying to locate the Hand of God for years. I mean, if James Cameron and his 'Avatar' billions can't find it..."

"Yeah, but we have something that James Cameron doesn't have," Catty told them.

Dean, Amara, Ness and Sam looked at Catty in confusion.

Catty looked at Castiel and Sabrina.

Dean, Ness and Sam realized that she meant time travel, looking at Castiel and Sabrina.

Sabrina looked between them in confusion, wondering why they were looking at them.

    §   

Stuart, Florida

Park

Sabrina and Levi were walking in the park.

"Going from looking for your aunt Ava to looking for Hands of God," Levi told her. "You never slow down, do you, Sabrina?"

"It makes it hard for people to keep up," Sabrina told him. "Levi, do you think that I can use one against the Darkness?"

Levi nodded. "The power of a Hand of God added to the True Hybrid's power would be... tremendous. I'm not sure if it would be enough to kill her, but at least to find a way to disarm her."

"Well, like my mom always says," Sabrina told him. "There's only one way to find out."

"And it was Catty's idea for you and Cas to go back in time to get it?" Levi asked.

"Yeah," Sabrina answered. "It's just that..."

Sabrina trailed off, not knowing how to finish.

Levi looked at her curiously. "You've never time traveled before, have you?"

Sabrina shook her head. "Mm-mm. My dad and Aunt Ava were starting to teach me about it, but we never actually gone into it completely, because Dad and Aunt Ava were more focused on teaching me how to create a smiting storm that was infused with my own powers so I could exorcise the Darkness out of Amara. So, I don't know how to time travel, and my dad said that he can channel my power to get us back there, but..."

"Cas can't channel all that power alone without something bad happening," Levi finished.

"Right," Sabrina agreed. "So we were hoping that you could come back with us. I might not know how the hell to time travel, but you and my dad do, Levi. All you have to do is channel enough of my power to get us back there."

"All right," Levi told her. "When were you planning on doing this?" Sabrina smiled a small smile. She stopped walking, sensing something. The female Demon from the asylum was across the park, listening. Sabrina turned around, looking around. The female Demon had disappeared. Sabrina looked confused. "What?"

"I thought I sensed a Demon," Sabrina answered. "I don't know. Maybe not."

    §   

Hell - Throne Room

Octavia/Lucifer was still sitting on the throne, pulling Octavia's Angel Sword out of her jacket, putting the tip of the blade on the floor, twisting it in boredom.

Crowley was sitting on the floor next to the throne, still chained up.

Two male Demons opened the double doors to the room.

Two female Demons pushed a cart of medieval weapons inside.

Octavia/Lucifer stood, walking toward the cart, sighing in disappointment. "That's all of it?"

"Yes, sir," Demon 1 answered. "The requested weaponry from your crypts. Does it... please you?"

Octavia/Lucifer rolled her eyes. "Spare me." He gestured for all of the Demons to leave. The Demons walked out, leaving, closing the doors behind them. Octavia/Lucifer walked toward Crowley. "How are your wounds, puppy?"

"They are..." Crowley trailed off, clicking his tongue. "No less than I deserve."

Octavia/Lucifer placed a hand on Crowley's shoulder.

Crowley winced.

Octavia/Lucifer chuckled in amusement. "Aw. You're scared of your master." He clicked her tongue, petting Crowley on the head. "That's a good puppy." He dripped Crowley's ear, pulling his head up, making him groan in pain. "But it's an act. I broke you, but, um..." He leaned closer to inhale Crowley's scent deeply. "Yep, I can still smell it. You've got that delectable little whiff of defiance. You're just playing, huh? Waiting for your moment to retake the throne. Am I right?"

"Yes, sire," Crowley answered.

Octavia/Lucifer let go of his ear. "Well, then, tell me, uh, once and future..." He chuckled. "King of Hell. You've been watching my rule. What treasonous thoughts do you have brewing in that little head of yours, huh? What are you really thinking? Hmm?"

"The truth?" Crowley asked.

"Yeah," Octavia/Lucifer answered.

"You're not strong enough," Crowley told him. "You've had your weapons delivered. You realize they won't be enough. If you thought you could beat the Darkness, you'd be taking the fight to her. Right now. You know that you will need the help of extraordinary magic, and the True Hybrid, but you also know that Sabrina Winchester would sooner exorcise you out of Octavia's vessel and send your ass back to the Cage before she would ever team up with you to defeat the Darkness."

Octavia/Lucifer placed a hand on Crowley's shoulder. "You're a clever little puppy." He pulled the hand back. "You're right. At the moment, I--I may be a bit under equipped. Maybe defeating the Darkness was a bit more of a team effort than I led certain people to believe. And I know that Sabrina Winchester wouldn't dare let me wander the Earth inside her 'Aunt Ava' or work with me to take down the Darkness. That's why I'm having your... I'm sorry, my... Demons keep a close eye on Sabrina and Levi. Levi's that little Angel friend of hers that she's been conspiring with to find me. So that when they're ready to make their move, I can sweep in and take the leverage that I need to make her work with me. You know, all that said..." He placed the tip of Octavia's Angel Sword underneath Crowley's chin. "I'm still your master. Did I let you out of that kennel too soon?"

Crowley shook his head, whispering. "No."

The female Demon from the park walked in. "And I now know what move Sabrina and Levi are planning on making."

Octavia/Lucifer looked at the female Demon, smiling.

    §   

Lebanon, Kansas

The Bunker - Control Room

Sam, Dean, Catty and Castiel were in the control room, setting up three boards with research and coordinates and the date and time the USS Bluefin had gone down.

"All right, the ship went down on February 17, 1943 at 38.4667 N, 28.4000 W," Sam told them.

"Well, that should be enough to get us on the ship," Castiel told us.

Sabrina appeared behind them. "Yeah, the three of us. Me, Dad, Levi." Sam, Dean, Catty and Castiel turned around to look at Sabrina and Levi. Ness and Amara walked in from the library. Amara was holding Aiden. "Mom, Uncle Sam, Uncle Dean, Aunt Ness, this is Levi. The Angel I told you about. Dad, Amara, you know Levi."

"I wouldn't call 'one of the first things I see when I wake up as myself is you sending Levi away to save him from the Darkness' as 'know Levi'," Amara told her.

Ness looked at Levi. "So, you're the Levi that's been helping Sow look for Ava."

Levi nodded.

Dean looked overprotective, trying to be intimidating. "The Levi that Sow's been hanging out with a lot here recently."

"I... guess so," Levi answered.

Sam looked overprotective, trying to be intimidating. "Hmm."

Sabrina looked at the ceiling as if she was thinking, please don't do this. "Oh, God." Levi looked at Aiden curiously. "Oh, and that's Aiden." 

Aiden looked at Levi curiously, smiling. 

"And Aiden seems to like you," Amara told him. "Trust me, Levi, if Aiden didn't like you, or if you were bad, he would be screaming." Aiden laughed. Amara looked at Levi, nodding. "You're good."

Levi chuckled.

Castiel took a piece of paper off of a board. "So, these are the last coordinates. The Bluefin's last transmission to shore."

"All right," Levi told them.

"Wait a second," Sam told them. "Aren't there still risks with time travel? Aren't there consequences?"

Dean patted a hand on the table. "Sam, this is the ideal scenario."

"What?" Sam asked.

"The sub is a tin can floating in the middle of the ocean, doomed to go down," Dean told them. "You can't really mess with history at 20,000 leagues. So, we get in, get the weapon, get out. It's a milk run."

"And you think that t--this is a good plan?" Sam asked. "Sow doesn't even know how to time travel."

"No, but Levi and I do," Castiel told them. "Levi and I can channel Sabrina's power to get us to where we need to be. One Angel channeling the power of the True Hybrid could be deadly. That's why I asked Sabrina to bring Levi here."

"And that's also why you guys are staying here," Sabrina told them.

Catty raised her eyebrows. "Excuse me?"

"We don't know what's gonna happen back there, so you guys need to stay here," Sabrina told them.

"Stay here?" Catty repeated.

"I just want to be safe, and back there where we don't know what's gonna happen is not safe," Sabrina told them.

"When are we ever safe?" Catty asked.

"Mom, don't worry," Sabrina told her.

"C--Catty don't worry?" Dean asked. "Yeah, good luck with that, Sow."

Catty turned to give him a look. "Shut up, Dean."

Levi looked between them.

Castiel stepped closer to Catty reassuringly. "Sabrina, Levi and I can take care of this, Catty."

Catty looked at him seriously. "Cas. And you trust Levi?"

Levi gave them a what the hell? look for talking about him like he wasn't right there.

"Yes," Castiel answered. "Levi helped Ava and me in the war when no one else would. I trust him."

"So do I," Sabrina told them. Levi looked at Sabrina in slight surprise. Sabrina looked at Levi. "Yes, I trust Levi."

Sam, Dean, Catty, Ness, Castiel and Amara exchanged a surprised look, knowing that it wasn't easy for Sabrina to trust much of anybody easily.

Catty looked from Sabrina to Castiel, nodding. 

"All right," Ness told them. "Be safe."

"When are we not?" Sabrina asked. Dean scoffed. Sam gave Sabrina a look. Catty, Ness and Amara tilted their heads. Castiel smiled a small smile. "All right."

"Bon voyage," Dean told them.

Catty kissed Castiel for a moment, pulling away. She and Sabrina embraced, pulling away.

Castiel, Sabrina and Levi faced each other.

"All right," Sabrina told them. "Let's do this."

Castiel and Levi both put a hand on Sabrina's arms. They channeled her power through the touch. There was a bright white light that channeled through Sabrina's arms into Castiel and Levi's. All three of them disappeared in a flash of bright white light.

Aiden was in awe with the light.

Amara looked at Dean and Sam in amusement, nodding sarcastically. "Oh, yeah. Levi got the protective-uncle message."

Sam scoffed. "Damn right he did."

Ness smiled a small smile, nodding. "I'm sure."

Dean sighed. "Kids."

Aiden laughed adorably, the giggle ringing out through the room.

    §   

1943

Day - USS Bluefin - Storage Room

The bright white light appeared.

Castiel, Sabrina and Levi appeared alone in the storage room.

The bright white light faded.

Castiel, Sabrina and Levi took in their surroundings.

Sabrina sighed, looking around in confusion. "Well, this is different."

Levi nodded in agreement.

Castiel chuckled.

    §   

Ocean

The USS Bluefin gently cruised along the waves of the ocean.

    §   

USS Bluefin - Hallway 

Castiel, Sabrina and Levi waled along, invisible to the crew.

Two guys walked toward them.

"See, I enlisted to sink German ships," Man 1 told him.

"You're up," Man 2 told him.

Man 1 sighed, taking his hat off. "Let's go. Vacation's over. Now we got zip running patrols in the bay. Now Captain's got us going in the wrong direction? To run some mystery mission for some broad? Tell me how that makes sense."

"I wouldn't worry about it," Man 2 told him. "Get some rest."

"You now I can't rest," Man 1 told him.

The two men walked past Sabrina, Castiel and Levi without seeing them.

Sabrina looked at Castiel and Levi, shrugging, walking down the hallway.

Castiel and Levi followed.

    §   

Another Hallway

A cook was walking.

Delphine walked toward him. "When can I smoke?"

"When it's your turn, I'll let you now," the cook told her.

"Surely some of your boys take breaks in the engine room," Delphine told him, walking away.

The cook followed her.

    § 

Wardroom 

Delphine walked in, sitting down at the table.

The cook walked in. "Captain wants you to stay put."

"Let me guess," Delphine told him. "He fears I will distract his men. Does not want the skirt roaming the decks." She took out a cigarette, putting it in her mouth. "Give me the light."

"Ma'am, you're wearing pants," the cook told her, taking the cigarette out of her mouth, walking out, leaving.

Delphine watched him go in exasperation.

    §   

Hallway

Sabrina, Castiel and Levi walked through the hallway.

The Captain and a sailor walked past.

"Look out," the sailor called to the men. "Coming through. Coming through."

The Captain and the sailor walked past, leaving.

The cook walked past Sabrina, Castiel and Levi toward Man 1 from the other hallway. "Hey, Petey. Frog's sitting pretty like Queen of Sheba, getting room service in the wardroom, and I can't even grip, 'cause... well, you seen that dame?"

"Oh, yes," Petey answered. "You seen the gams on her?"

Petey whistled.

Sabrina, Castiel and Levi exchanged a look. They looked toward the wardroom, walking toward it.

    §   

Wardroom

Delphine sat at the table with a cigarette in her hand.

Sabrina, Castiel and Levi walked in, letting themselves become visible.

Delphine looked at them. "What are you doing on a ship like this?"

Levi sighed. "Delphine... you might find this hard to believe, but--"

Delphine stood, punching Levi in the chest, but it didn't even hurt him, only hurting herself. She held her fist in pain, only causing Levi to smirk in amusement. "Not a soul on this ship knows my name, so, who are you?"

"We're friends of Clifford Henshaw," Levi told her. "Cas here is a Man of Letters. Sabrina is a Woman of Letters."

"More like girl," Delphine told them.

Sabrina shrugged barely. "Well..."

"Sabrina is a Hybrid," Levi told her.

Castiel nodded. "Levi and I are both Angels."

"There's no such things," Delphine told them.

The cook, Petey and the Captain walked in.

"Is there a problem here?" Captain asked.

"No, no, no problem," Levi answered.

"Who are you?" Captain asked. "I know every face on this ship, but I haven't seen yours."

"All right, all right, don't make me do this the hard way," Sabrina told them. "Please? Just listen to me. All right? I really don't feel like erasing memories, because there's no point in it, so..."

Sabrina took out her cellphone, showing it to them.

Petey took it, looking over it curiously. "What the hell is this?"

"It's a phone," Sabrina answered.

Delphine took Sabrina's cellphone.

"Right, a phone in your pocket," the cook told her sarcastically.

"Next thing they're gonna tell us is they're from space, which would explain the weird clothing," Petey told them.

"Yeah, or the future," the cook agreed.

"We are," Castiel told them.

Levi looked at the Captain. "Captain James Dearborn? My name is Levi. These are my allies, Castiel, AKA, Cas, and Sabrina Winchester."

Castiel sighed. "And we are on a mission from the future, the details of which I am not at liberty to discuss. But know this. Within the hour, a German destroyer will find and attack this submarine, and you will go down."

Delphine looked down.

The cook, Petey and James looked skeptical.

Sabrina and Levi looked at Castiel.

Castiel looked at them seriously.

    §   

They were still talking.

"Okay, you've said your piece," James told them. "Let me tell you what I think."

"Captain..." Delphine trailed off.

James held up a hand to stop her, looking at Sabrina, Castiel and Levi. "I think you're soldiers gone AWOL. You've hopped a ride home on this cock-eyed story, in some loony attempt to keep your cover as civvies. That, or you're spies. Deciding which, I'll leave that to the Court Marshal."

"I need to speak with them alone," Delphine told them.

"Not a chance," James told her, drawing his gun, handing it to Petey.

"Captain, there are things, things about this mission that you don't know," Delphine told him.

"Princess Aura, Emperor Ming and Flash Gordon here will remain under guard until we reach the shore," James told them.

"Gladly," Petey told him.

Delphine scoffed. "What if we don't reach shore? What if they're right?"

"The odds of a German attack from a surface ship, this far west, hunting down a lone submarine?" James asked.

A sailor walked in. "Captain? Sonar's picked up a surface ship on a steady bearing, closing."

The cook, Petey, Delphine and James looked at Sabrina, Castiel and Levi.

Sabrina crossed her arms over her chest, raising her eyebrows expectantly, as if to say, Told you so.

James sighed. "Understood." He looked at the cook. "Harris, back to your station." He looked at Petey. "Giraldi, watch our guests."

"Yes, sir," Petey told him.

Harris, James and the sailor walked out, leaving.

Delphine looked at Sabrina, Castiel and Levi. "The Germans, they've come for it."

Sabrina sat across from her at the table.

    § 

Control Room  

James walked in to join the other crew members. "You're certain of the identification?"

"Yes, sir," a navigation officer answered. "Uh, 36 B German Destroyer, 3000 yards and closing, bearing 0, 9 and 0."

"Clear the bridge," James told them.

The sailor looked at the crew. "Clear the bridge!"

    §   

Wardroom

Sabrina and Delphine sat across from each other at the table.

Castiel and Levi stood next to them.

Petey watched over them. He looked at Castiel and Levi. "World Series, 1944. Go."

Levi looked at Sabrina. "Um..."

"You're from the future," Petey told them. "Tell me, who won?"

Sabrina gestured to Levi.

"Cardinals," Levi answered.

"Cardinals," Petey repeated, impressed. Sabrina was surprised that Levi knew that. "Okay, then. The next president."

Sabrina ignored him. "Delphine, you wanted the weapon to be at a Men of Letters safe house, right? Me, Levi and my dad? We're from the Bunker. That's how we knew how to find you, from your communication with Henshaw. Now, we can get it there for you."

"And that's why you came, to protect the object?" Delphine asked. "The weapon?"

Petey looked at Levi. "You gonna answer my question?"

"Eisenhower, okay?" Levi asked. "No. Uh, Truman. Now would you please shut up?"

Sabrina looked at Delphine. "No. This sub is going down. But the Allies do win. But from Woman of Letters to Woman of Letters? We're fighting a war in the future. It's not like your war. It's big. Biblical, end-is-nigh big. And we need your weapon to win. That is why we came."

"But we all die?" Petey asked. They looked at him. "Me, the girl, the rest of the crew?" Sabrina looked down. "I'm just trying to get your story clear."

Delphine looked at Sabrina, Castiel and Levi.

Sabrina looked at Castiel and Levi.

"Yes," Castiel answered. "Look, I now it's a lot to ask, especially from complete strangers."

Delphine looked at Castiel, shaking her head. "You're not a stranger, Man of Letters." She looked at Sabrina. "'Woman of Letters to Woman of Letters'. I trust you."

Sabrina managed a small smile.

    §   

Control Room

The crew continued to do their duty.

"Hatch secure!" a man told them.

James looked through the periscope. "Alt our course to 2-7-0. Take us down to 60 feet."

The sailor looked at the crew. "Alt our course to 2-7-0!"

"Altering course to 2-7-0," the navigation officer told them.

"Dive, dive, dive!" James told them.

The Bluefin dove underwater.

    §   

Now

Day - On the Road

Octavia's Camaro was driving crazily down the abandoned road on a mountain, taking the twists and turns expertly.

    §   

Octavia's Camaro

The hood was down.

Octavia/Lucifer was driving, enjoying the breeze tearing around, blowing Ava's hair all around. He drove the car with her knees, raising her arms above in the air, laughing ecstatically, evilly.

    §   

 On the Road

Octavia's Camaro drove away down the road just as fast and just as crazily, disappearing in the distance.

    §   

1943

USS Bluefin - Wardroom

Sabrina and Delphine were sitting across the table from each other.

Castiel and Levi stood next to them.

Petey watched over them.

Delphine put a wooden box onto the table, opening it.

A cloth was covering the object.

What looked like golden wood was inside.

"That's the Hand of God?" Sabrina asked. "Doesn't look like much."

Delphine smiled a small smile. "No, I suppose it doesn't. It must have been more impressive in its complete form. The Ark of the Covenant."

Sabrina raised her eyebrows. "Oh, so full-on 'Raiders'. That's... okay."

Levi smirked in amusement.

Sabrina reached out to take the Hand of God from the box.

Levi placed a hand on hers to stop her. "Don't touch it bare-handed. Its power is potent and unstable. You activate its power with direct contact, and a Hand of God can only be used once."

"One time?" Sabrina asked.

"Unfortunately, because it was so long ago that He had touched these objects," Levi answered. "In time, the power fades, but it's still enough to defeat any enemy. Any war. But you have to be smart when you use it, or it will be all for nothing."

Delphine covered the Hand of God with the cloth again, closing the box, sliding it toward Sabrina.

"When?" Petey asked.

"When what?" Castiel asked.

"When do we win?" Petey asked. "Months, years, decades? Got a lot of friends and family on other ships, in other branches. I want to know what their chances are."

Castiel nodded. "Years. 1945. You believe us?"

Petey nodded. "I read a lot of 'Flash Gordon'."

Castiel smiled a small smile, looking down.

    § 

Control Room  

The crew were still doing their duty.

"15 hundred yards," the navigation officer told them. "We are not shaking them."

"Battle stations!" James told them.

"Sir, respectfully, our orders were to go home," the sailor told him. "Not engage."

"That so?" James asked. "Do not make me repeat myself."

The sailor looked at the rest of the crew. "Battle stations!"

    §   

Wardroom 

Sabrina and Delphine sat across the table from each other.

Castiel and Levi stood next to them.

Petey watched over them.

The lights went out.

The red emergency lights started to flash.

Man: (on PA) "General quarters, man your battle stations. All hands, man your battle stations."

    §   

Hallway

The soldiers and sailors spilled out of their quarters, running toward their battle stations to prepare themselves for action. 

"Let's go, boys!" a man told them. "Let's go. Come on. Come on. Let's go. Let's go. Let's go. Let's go. Keep it going. Keep it going. Go. Get to it. Get to it. Everyone in positions."

    §   

Wardroom 

Sabrina and Delphine sat across the table from each other.

Castiel and Levi stood next to them.

Petey watched over them.

They all looked at each other.

    §   

Control Room

Everyone was at their battle stations.

"Stand by to load two number eight," an officer told them.

"Load aft torpedo," James told them.

"Load aft torpedoes," Harris told them. He and the other soldiers started to load the torpedoes. "Ready to fire."

"Ready to fire," another officer repeated.

"800 yards and closing," the navigation officer told them.

"Torpedoes loaded," the sailor told them.

"Line us up for a bow shot," James told them.

"Line up for a bow shot!" the sailor told them.

"Lining up for bow shot," Harris told them. "Locked."

"In position," the sailor told them. "Ready to fire."

Everything fell quiet.

"Captain!" the navigation officer told him. "I've--I've lost its position."

"What?" the sailor asked.

"He's gone," the navigation officer told them.

"How is it possible to lose a 3,000 ton warship from 800 yards?" James asked. "Find him."

There was a banging noise from above them.

"30 yards, sir," the navigation officer told him. "He's right on top of us. How?"

"For negative, take us down to max depth and rig for silent running," James told them.

"Silent running!" the sailor told them.

The Bluefin descended deeper into the ocean.

    §   

Wardroom

Sabrina and Delphine were sitting across the table from each other.

Castiel and Levi were standing next to them.

Petey was watching over them.

The submarine lowered all the way as low as it was allowed to go.

Everything fell silent.

Sabrina heard a clanking in the distance. "What's happening?"

Petey put a finger to his lips. "Shh, shh."

Petey pointed at the ceiling above.

They were all whispering.

Delphine stood, looking at Sabrina, Castiel and Levi. "You need to leave."

Sabrina stood. "They're coming."

"What are you going to do?" Petey asked. "You gonna save us?"

"Why not?" Sabrina asked.

"Sabrina," Levi told her. Sabrina looked at Delphine. "Sabrina." 

Castiel took the box with the Hand of God from Sabrina. 

Sabrina looked at them for a moment, irritated and upset that she couldn't save them, walking out of the room.

    §   

Ocean

Above the Bluefin, what looked like a bomb had been dropped into the water. It was descending toward the submarine.

    § 

USS Bluefin - Control Room  

The crew were still doing their duties, at their battle stations.

"Splashes," the navigation officer told them. "Depth charge."

Everyone looked upward with intense apprehension.

    §   

Hallway

Sabrina walked into the hallway. Castiel followed her with the box. Levi stopped next to them.

"Why can't we save them?" Sabrina asked.

"Because altering the time line is dangerous," Castiel answered. "If we save them, what will be the consequences?"

"What do you mean?" Sabrina asked.

"I mean, if we save these people from dying, and their bloodlines live on, that makes about 50,000 more people to be in the world in the present," Castiel told her.

"And what's so bad about that?" Sabrina asked.

"The Fates will go through each and every one and kill everyone that is alive because of us," Castiel answered. "Trust me. It's happened before. If we save these people, there will be at least 50,000 deaths. And never being born is a lot different than being killed horribly."

Levi walked closer. "They are supposed to die, Sabrina. But we don't have to let them die in vain."

Sabrina hesitated, not knowing what to say. "Levi..."

Levi sighed. "Cas, Sabrina, let's go home."

Castiel walked away down the hallway.

Levi looked as if he was about to follow, turning to Sabrina.

Sabrina still looked upset.

    §   

Ocean

The bomb reached the Bluefin, exploding one end of the submarine.

    §   

USS Bluefin - Control Room

Everyone fell over, stumbling, looking around wildly, terrified.

    §

Petey and Delphine fell over, stumbling, looking around wildly, terrified.

    §   

Ocean

Another bomb reached the Bluefin, exploding.

    § 

USS Bluefin - Hallway  

The submarine tilted to the side, making everyone fell to the left.

Castiel was barely able to stay standing, catching himself against the wall, holding the box with the Hand of God to his chest so nothing would happen to it.

Sabrina was forced to fall back into the wall behind her, still standing. Levi was forced to stumble toward her, barely able to catch himself against the wall in front of him. They looked at each other, breathing heavily.

    §   

Now

The Bunker - Library

Dean, Amara and Ness were sitting at one of the tables.

Ness was holding Aiden, researching the Bluefin.

Sam and Catty were sitting at the other table.

Aiden started to fuss. After a moment, he started to cry.

Everyone looked at him. "Aiden?"

"What's the matter, Aiden?" Dean asked. "What's wrong?"

They heard the door open, looking up, everyone tense.

Dean, Sam and Catty stood. Dean and Catty drew their guns. Sam drew an Angel Blade. Ness stood, backing away with Aiden in her arms. Amara stood next to her.

Octavia/Lucifer walked in. "Hey, guys. You expecting someone else?"

Dean, Sam and Catty sighed, lowering their weapons.

"Where have you been?" Dean asked.

"I told you before," Octavia/Lucifer told them. "That I'm looking for a way to lure out the Darkness."

"Yeah, but you didn't say that you would be gone for months on end with little to no contact and without us seeing you since then," Ness told him.

Octavia/Lucifer sighed, stepping closer. "I'm sorry. But I felt as if I was being followed. Like she was everywhere and no place to be found. I--I couldn't risk calling and luring you right to her or her right to you."

Aiden was still crying.

Sam looked at Octavia/Lucifer. "Are you okay?"

"I've... been better," Octavia/Lucifer told them.

"What are you doing here, now, after so long?" Catty asked.

Octavia/Lucifer took a deep breath. "Sabrina and Cas called me. Told me of her plan to go back in time and retrieve a Hand of God."

"And Cas told Sabrina to bring Levi here instead of you why?" Catty asked.

Octavia/Lucifer stepped closer. "Because I hadn't answered Cas and Sabrina's call." Aiden's crying increased. "They left me a message. I drove here as soon as I had gotten it."

"And you were out there, alone, when it took everything Sabrina had to exorcise the Darkness from Amara and caused them all to be unconscious for an entire day," Sam told him. "You didn't think it would be dangerous to be out there alone after that happened?"

"Yes, I knew it would be dangerous," Octavia/Lucifer told them. "I just wanted the danger to be off of your shoulders."

Amara nodded, unconvinced. "Yeah. Sounds like Aunt Ava."

Octavia/Lucifer looked between them, smirking. "You're not buying any of this, are you?"

"Not even a little," Amara answered.

"See, Sabrina was so worried about what happened to Ava, hoping so hard that it was nothing and that what it looked liked was what it was, but we all knew that Ava would always come around," Sam told him. "Ava wouldn't disappear like you did. Sow thought it was because of the Darkness, like some kind of petty revenge for almost killing her, for expelling her out of Amara's body. But I realized that Ava hadn't been acting like herself since we got out of Hell. Since you wanted a vessel to get out of Hell." Octavia/Lucifer looked raised her eyebrows. "We know who you are, Lucifer."

Octavia/Lucifer looked between them, smiling. "In the flesh."

Octavia/Lucifer smiled, laughing maniacally.

    §   

Aiden was still crying.

Octavia/Lucifer walked closer, smirking. "Well, the jig is up."

Aiden cried louder with every step he took step closer.

Ness backed away with Aiden in her arms, stepping closer to Amara. "Aiden, shh."

Aiden tried to calm down enough to say the one word. "Bad." Ness looked at him in surprise. "Bad."

"'Bad' is right," Octavia/Lucifer told them. "You know that Aiden can sense my presence? I mean, me me, not your little Ava. Aiden can feel the evil radiating from me. I think you all know that the Mark of Cain had an effect on both Aiden and Amara since Ness had the Mark while pregnant with Amara and Aiden. And I'm talking about more effect than the Darkness taking Amara for possession."

Ness started to hand Aiden to Amara. "Amara... get Aiden out of here."

Octavia/Lucifer smirked. "Who knows the kind of effects that Aiden and Amara could show in the future?"

Ness glared at Octavia/Lucifer, handing Aiden to Amara.

"Amara, take Aiden to his room," Dean told her. "Stay there with him."

Amara took Aiden, backing away, hesitant to leave. "Dad. Mom..."

"Go," Dean told her.

Amara hesitated, running out of the room with Aiden.

Octavia/Lucifer watched her go, smiling. "See the thing is, I don't need you anymore. I mean, Catty's the best way to get to Sabrina and Castiel, and Levi, once they get back. And the Darkness feels indebted to Dean and Ness because of the Mark, because they set her free, because she took Amara from all of you, including little Aiden. Dean, Ness, Amara and maybe even little Aiden still may be essential in drawing her out. So, why have I been trying to spare you, Sam? Maybe it's because you're like the girl who kept turning me down at the prom." Sam ran closer with a blade. Octavia/Lucifer deflected the blow, pushing Sam across the room, making him fall. Dean ran toward Octavia/Lucifer with a blade. Octavia/Lucifer elbowed his wrist to make him drop it, grabbing Dean, turning around, throwing him into a bookshelf, making him fall. Octavia/Lucifer went to pick up the Angel Blade from the floor. Catty shot her in the shoulder, making him stop, kicking the blade toward Ness. Ness picked up the Angel Blade, spinning it in her hand. Octavia/Lucifer used magic to throw the gun out of Catty's hands, grabbing her arm, spinning her around so that her back was to him, restraining her, aiming Octavia's Angel Sword at Catty's throat to stop Sam, Dean and Ness from making a move. "Levi, Sabrina and Castiel will be back soon with the, uh... Hand of God."

"Yeah, and they'll see you for who you really are, you son of a bitch," Catty told him. "They'll know that you're not Ava."

"Then they'll know that the only way to save you and to save, um, Aunt Ava is to give me the Hand and all will be good, Catty," Octavia/Lucifer told her. "And if it will make it any easier for them, I'll make them think that Ava has a modicum of control for a second. I'll tell them, 'Levi... Cas... Sabrina... he's powerful. He will kill everyone if you don't obey him. Do what he says. Just give him what he wants.'"

Sam closed his eyes in horror at seeing Ava this way.

    §   

Hallway

Amara ran through the hallway with Aiden in her arms.

    §   

Nursery

Amara brought Aiden inside to his crib, laying him down.

Aiden was crying, sitting up, looking up at Amara.

Amara looked heartbroken and conflicted. "I know, Aiden. It's horrible. But Sabrina and Uncle Cas and Levi will be back soon. And we're gonna save Aunt Ava. I promise."

Aiden continued to cry.

Amara looked toward the door, conflicted.

    §   

Library

Octavia/Lucifer was still restraining Catty with her back to him, aiming the Angel Sword at her throat, lowering the blade, turning around, throwing her to the floor. He turned to Ness.

Ness raised the Angel Blade she was holding toward Octavia/Lucifer in defense. "You really think that they're stupid enough to give it to you? I mean, you?"

"Cas is in love with Catty," Octavia/Lucifer told them. He remembered something, turning to Catty tauntingly, smiling. "So much so that I've heard the recent news of you two finally tying the knot. Congrats!" Catty glared at him. "And Sabrina is a Winchester, and she is Catty and Cas' daughter. I think they will do whatever it takes to save the ones that they love, no matter the consequences. You know that's why Ava is in this mess, right? You know the exact moment she gave herself over to me? Vomiting blood, liquefying organs... Ringing any bells? Sam, Dean and Catty were all gonna die, Ness. Ava made sure it didn't happen. If you've all corrupted Ava with all of this family love and loyalty nonsense, I'm pretty sure that Cas is just as corrupted, and that Sabrina's been raised with it. And Levi owes Sabrina for saving his life from the Darkness after she exorcised her from Amara, making it possible to bring her home to all of you and Aiden. Levi would do anything to repay that favor, including spending months looking for Sabrina, Aiden and Amara's Aunt Ava, and saving their family. What do you think Cas, Sabrina and Levi will do to save all of you? Winchesters and Singers, man, I'm telling you."

They didn't answer.

"So, how did you really find out about all of this?" Sam asked.

"Oh, I've had Demons tracking little miss Sabrina and her little Angelic crush Levi for a while now," Octavia/Lucifer told them. "Told them to keep their distance, not to get caught so they wouldn't be able to take them off the map so they could report back to me. And when they told me that Sabrina and Levi were time traveling with Cas to get a Hand of God... oh, I knew that I had to come on down."

Dean stood angrily. "They're not gonna give it to you. They'd sooner use it to kick you the hell out of Ava's body and then use it to kill you."

Octavia/Lucifer frowned sarcastically, pretending to think. "Really? In that case, there's really no reason to keep any of alive, is there?"

Octavia/Lucifer used magic to throw the Angel Blade out of Ness' hand, grabbing her, turning to push her against the bookshelf. Ness kneed him in her stomach, punching him in her face twice, grabbing a vase of flowers from the nearby table, shattering it over her head.

Dean grabbed Octavia/Lucifer, pulling him away from Ness.

Octavia/Lucifer drew Octavia's Angel Sword.

Amara was standing behind the nearby bookshelf for cover, to hide, having a gun at her side.

Octavia/Lucifer used magic to push Sam, Catty and Ness into the walls, pinning them. He took Dean by the collar of his shirt, raising the Angel Sword to stab him. Ava's hand was shaking as if she was fighting for control.

Ness struggled desperately. "No!"

Amara aimed her gun at Octavia's Angel Sword, shooting it to make it fall out of her hand to the floor, making it slide away across the room. 

Octavia/Lucifer let go of Dean, pushing him to the floor, turning to face Amara. "Impressive, Amara. You really are a Winchester."

"I take after my mom and dad," Amara told him.

Octavia/Lucifer started to walk toward Amara. "You're gonna die just like them, too."

Amara fired shots into Octavia/Lucifer's shoulders and chest, having no effect.

Octavia/Lucifer had to pause in walking. Octavia was fighting for control. Lucifer was trying to shove her back down.

Sam struggled against the magical restraint. "Ava!" 

Octavia was still fighting for control, breathing heavily, finally taking it back.

Sam, Catty and Ness were let off of the wall. They walked toward Dean and Amara worriedly, pulling them away from Octavia/Lucifer.

Octavia/Lucifer was annoyed, fighting to get control back. "Hello, Octavia."

Harris found a fallen soldier, yelling for help. "We need a medic!"

Control Room

The Bluefin was now taking in water.

The situation looked dire.

"Situation report," James told them.

"Battery room is flooded," the navigation officer told them. "Hull's breached."

"We're dead in the water," the sailor told them.

"Ship's locked in position above us," the navigation officer told them.

"Captain," another officer told him. "The Germans are sending a message. Sir. It's not for you."

    §   

Later

Petey led Delphine, Castiel, Sabrina and Levi into the room.

James nodded to the navigation officer. "Go ahead."

The navigation officer made sure they could all hear the message.

The man from the teaser's voice was on the other line. "Hello, meinliebchen. [My love.]"

Delphine was in shock, disbelief. "It is not possible. I killed you."

"A little advice, Delphine," the man told her. "If you want a friend of the Thule to stay dead, burn the body."

Sabrina looked up in surprise. She realized who they were dealing with, sighing, rolling her eyes. "Oh, great."

"What?" Levi asked.

"The Thule Society," Sabrina answered. "I've dealt with them before, and I didn't like it the first time."

"A word for the Captain," the man told them. "You may have noticed you are up against a warship and a crew possessing, let us say, extraordinary abilities. And you have taken damage that you cannot recover from. So, I offer you a choice. Surface now, relinquish the girl and her cargo, and I can assure you and your men the highest of POW treatment. Or you can protect her, and we will depth charge you and your boat right into the seabed and recover the cargo ourselves. You have three minutes to surrender."

Everyone looked at Delphine.

"I don't expect you to understand," Delphine told them. "But this cargo? The Germans can't have it." She exhaled heavily. "You need to believe me."

"Our orders were to protect you and your cargo," James told her. "We wouldn't even consider a surrender."

Delphine looked at Castiel, Sabrina and Levi. "You need to go." She looked at the box in Castiel's hands. "Take it. Leave. Win your war."

Sabrina was still unhappy, walking out, leaving.

Castiel and Levi sighed, following her.

    §   

Hallway

Castiel and Levi walked toward Sabrina.

"Sabrina..." Levi trailed off.

Sabrina turned to face them, making them stop. "I'm going to kill them, Levi."

"The Thule?" Levi asked.

"Yes, the Thule," Sabrina answered. "You told me what would happen if I messed with the timeline and saved the people--good people--on this ship. And I get it. I do. But do not tell me not to kill the monsters that are responsible for this."

Castiel sighed. "You're gonna go after them no matter what I say, aren't you?"

"Yes," Sabrina answered.

Levi gave in. "All right. Go for it. Give it all you got, Sabrina."

Now

The Bunker - Library

Octavia was shaking from the effort it took to take control back from Lucifer, falling to her knees on the floor. "Sam..."

Sam knelt in front of her worriedly. "Ava?"

Catty, Dean, Ness and Amara walked closer, standing behind Sam.

"Aunt Ava?" Amara asked worriedly.

"Ava, why?" Ness asked.

Octavia looked at Sam, Dean and Catty. "He was going to kill you, all of you. I couldn't let that happen. You would've died for nothing, and Cas, Sabrina, Aiden, Ness and Amara would be left alone here, having lost everyone, when they need all of us."

"You have to fight, Ava," Ness told her. "Eject him now."

"I can't," Octavia told them. "It's taking all my strength to keep him from killing all of you."

Sam looked at her desperately in worry. "Ava..."

Octavia put her Angel Sword in Sam's hand, taking his other in her other hand. "You'll save me, Sam." She looked at Sam with tears in her eyes. "I know you will. I'll come back for that, just like I did before. I promise you, Sam."

Sam didn't know when they could save her, but part of him knew that it wasn't going to be that night. He didn't know when, and he didn't know how long it would be. He put a hand on Octavia's cheek, kissing her softly, passionately for a moment. Octavia held her hand to his shoulder. They pulled away after a moment, remaining close, leaning their foreheads together. Sam looked down, a few tears escaping. Octavia looked at him sadly in regret.

    §   

1943

German Destroyer

The Thule had resumed their attacks on the USS Bluefin.

Castiel, Sabrina and Levi appeared.

Castiel held the box with the Hand of God.

Sabrina walked into the middle of the ship.

The Thule soldiers saw them, aiming guns at them, shouting in German in confusion.

Sabrina held her hands to her sides, closing her eyes in concentration. Bright white light started to emanate from her hands and chest. Shadows of unfurling wings appeared on the wall behind her. She opened her eyes. They were completely white, glowing blue from within.

The ship started to shake and crumble, slowly at first.

As more time went on, the more violent it became, debris and glass and electrical sparks falling around them.

Castiel watched proudly.

Levi watched in awe.

Sabrina raised her arms above her head. She was glowing with bright white light. Everything was glowing around her. She threw her arms down to her side, using magic to make the ship start to crumble more quickly, more violently.

The ship started to break apart, allowing water inside.

The light was starting to burn the Thule through, slowly eating away at them, making them scream in agony, until they burned away with the light completely.

Water flooded the destroyed ship.

    §   

Now

The Bunker - Library

Catty, Dean, Sam, Ness and Amara were backing away from Octavia/Lucifer.

Octavia/Lucifer stood, chuckling. "So emotional. So much drama with you all, isn't it?"

Castiel, Sabrina and Levi appeared behind Octavia/Lucifer with a flash of bright white light.

Castiel was holding the box.

Catty was breathing heavily. "Levi... Sow... Cas..."

Sabrina looked at Octavia/Lucifer, with her back to them. "Aunt Ava? Where the hell have you been?" Octavia/Lucifer smirked, turning to face them. Castiel, Sabrina and Levi could see Lucifer's face. "Not Aunt Ava."

"No, I'm not," Octavia/Lucifer answered. "But Ava's still in here. Ava says hi, by the way."

"Who the hell are you?" Sabrina asked.

"That's right," Octavia/Lucifer told her mockingly. "We haven't been formally introduced. Maybe your father Cas or new Angel crush Levi would like to do the honors."

Levi was in shock, horrified. "Lucifer."

Sabrina looked from Levi to Octavia/Lucifer in shock.

Octavia/Lucifer smiled. "Cat's out. Right, Catty?"

Octavia/Lucifer smirked, winking.

    §   

Octavia/Lucifer grabbed the box from Castiel, pushing him over one of the tables, making him fall to the floor on the other side. "Mm! I feel a burden lifted. You know, this whole 'deep cover' thing? It just wasn't--it wasn't terribly well thought out. I mean, well... as I've said before, Ava was definitely one of the more funny Angels since the dawn of man, but, well..." He chuckled, shrugging. "Feelings. Just ugh." He looked at Sam, Dean, Catty and Ness. "And then teaming up with you four? I mean... I thought you guys were insufferable as mortal enemies." He inhaled sharply. "But working with you? That's the soul crusher."

Octavia/Lucifer held the box in front of him, going to open it.

Sabrina grabbed Octavia/Lucifer, turning around, teleporting them out of the Bunker.

Amara, Castiel, Sam, Dean, Catty and Ness knew that Sabrina would have taken the fight outside, running toward the stairs. Levi followed shortly behind.

    §   

Outside

They ran outside.

Sabrina pushed Octavia/Lucifer back, punching her in the face to make him let go of the box, taking it away from him. Octavia/Lucifer tried to punch her in the face. Sabrina blocked the move. Octavia/Lucifer tried to punch her. Sabrina blocked the move. Octavia/Lucifer spun to try and kick her. Sabrina raised a leg to block the move, spinning around to backhand punch Octavia/Lucifer in the face, backing away. She stumbled slightly, looking at little under the weather.

"Oh, you don't look so good," Octavia/Lucifer told her. He tilted her head mockingly, smirking. "Did you overexert yourself today?"

Sabrina held the box in front of her, opening it slightly, looking inside the box. "Something like that."

Sabrina closed the box, raising her gaze to look at Octavia/Lucifer, trying to punch him. Octavia/Lucifer caught her arm, twisting it behind her back, pushing her away. Sabrina spun to face him.

    § 

Inside - Map Room  

Levi was at the entrance of the Bunker, about to walk outside. There was a bright flash of light. The Hand of God appeared before him.

    §   

Outside

Octavia/Lucifer used magic to throw Sabrina into the brick wall of the building, making her fall to the ground and drop the box. He walked closer. "You're not used to fighting against entities with equal power, are you, Sabrina? I got to say, I'm not, either. But then again, I didn't use hardly any of my power today, but you seem to have used more than your fair share. I mean, between going back in time, smiting a submarine with Thule on it to their deaths, and then coming back to present time, that's just a lot of power used in one day, and after what you did to exorcise the Darkness from Amara, it's no wonder that you're still healing, and why you're exhausted after such display of power today, since you're still healing. You know what? The Darkness is still healing, too, somewhere, but she's a lot worse off than you are. But after all the power you expended today while still healing? Ooh, you put yourself in a vulnerable position, though you're still putting up a very good fight. I grudgingly admit that I'm impressed, Winchester." Sam, Dean, Catty and Ness took a step forward. Octavia/Lucifer held a hand toward them, using magic to keep them back. Castiel drew his Angel Blade, lunging forward. Octavia/Lucifer deflected the blow, grabbing Castiel, flipping him to the ground, stepping onto his throat. "Why the faces, guys? You should be cheering. We have a common enemy." He picked up the box from the ground. "With this, she will be no problem. I mean..." He chuckled. "I will have killed you all by then, except for Sabrina since she can't die, but still. Come on."

Octavia/Lucifer opened the box, revealing the cloth inside.

"No," Castiel told him. Octavia/Lucifer started to open the cloth. "No!"

Octavia/Lucifer revealed that the box was empty. He looked up in annoyance, closing the box, tossing it aside.

Sabrina slowly stood. "You really think that I would let you have anything other than an empty box?"

Sabrina walked toward Octavia/Lucifer in determination.

Octavia/Lucifer pulled Castiel up from the ground, restraining him from behind, holding his Angel Blade to his throat. 

Sabrina stopped before she could make another attack.

"Give me the Hand of God, Sabrina, or your father will be put to sleep permanently with the dead," Octavia/Lucifer told her. "You don't want to lose Cas, do you, or for Catty to lose her husband, again?"

"I don't have it," Sabrina told them.

Levi walked closer. "I do."

Levi held the Hand of God in both hands in front of him, one hand beneath the other. It started to glow gold. The power entered his body, visible from beneath his skin. Levi started to illuminate with bright white light. He chuckled at the euphoric feeling. The glow faded.

Sabrina took advantage of Octavia/Lucifer's distraction, using magic to pull the Angel Blade out of his hand, into hers. She used magic to push Octavia/Lucifer back, making him let Castiel go.

Castiel stumbled away.

Catty pulled Castiel toward her worriedly. "Cas."

Levi held his hand toward Octavia/Lucifer. It started to glow with bright white light.

The bright white light enveloped everything.

Octavia/Lucifer, Sabrina, Sam, Dean, Catty, Castiel, Ness and Amara closed their eyes at the brightness.

The light finally faded.

Sabrina, Sam, Dean, Catty, Castiel, Ness, Amara and Levi looked around.

Octavia/Lucifer was gone.

Everyone looked at each other, breathing heavily.

    §   

Dock 

The family was on the dock together.

Dean, Ness and Amara were sitting on a bench with Aiden.

Catty, Castiel and Sabrina were sitting on the bench across from them.

Sam was looking out over the water numbly. "So, Ava's okay?"

"Yeah," Castiel answered. "And Lucifer's still possessing Ava. Levi just sent them away. He... Levi could've killed them. Both of them. But he didn't. Levi chose to let Lucifer walk, in order to save Ava, sending them away, to save the rest of us."

"What do we do?" Amara asked.

"What else?" Dean asked. "We hunt Lucifer, trap the bastard, and save Ava."

Sam turned to face them.

"Sam," Ness told him. Sam looked up. "We will save Ava. I promise you."

Sam nodded. "I know."

Amara looked at Castiel and Sabrina. "So, how'd you two and Levi get through today? I mean, what did Lucifer mean about what you did that took such a toll on you?"

"You know what happened to the, uh, the German ship that sank the Bluefin?" Sabrina asked.

"It went down," Ness answered. "The only thing that was found was wreckage. Um, it was like an explosion, but it wasn't a regular fire. But it burned. Sank."

Sabrina sniffled. "Yeah. I made sure that it happened."

Sam frowned in confusion. "You're the one that sank the boat?"

Sabrina nodded. "The same way I took down Cain. The, uh...  the Thule Society were the ones behind it. They were the ones that found the Hand of God and wanted Delphine dead. I wanted to save the people on the Bluefin."

"Levi and I told her about what happened when Balthazar went back to save the Titanic, with the Fates and the descendants of the survivors dying horrifically," Castiel told them. 

"But I couldn't just do nothing," Sabrina told them. "The Bluefin was already a goner. But I didn't want to let the Thule get away with it, so I burned them to ashes."

Catty took a deep breath, looking down. "Oh."

Sabrina slowly, barely, shook her head. "I shouldn't have done that. I don't regret taking down those monsters, but... I spent so much power on killing them... when I needed that power to face Lucifer..."

"You were just doing your job, Sow," Amara told her. "You didn't now that there was another job waiting for you at home. How could you about Lucifer?"

Sabrina looked at Sam sadly in regret and guilt, tears in her eyes. "I... I knew something was wrong with Aunt Ava. I--I--I knew it. I just wanted to believe that things were like she said. That nothing was going on. But of course something was going on. And it's worse than what I thought. And it's my fault."

Sam shook his head. "No."

Sabrina stood. "I should have told you how worried I really was months ago. And I tried to find her. I tried so hard, Uncle Sammy. But I couldn't. And Aunt Ava's still in this mess because of me."

Sam pulled Sabrina into an embrace. "Hey. No. It doesn't matter. Okay?" They pulled away. "We're going to find Ava, and we're going to save her."

Catty and Castiel stood, walking closer.

"Sabrina, you were able to exorcise the Darkness from Amara's body," Catty told her. "Of course you're going to be able to exorcise Lucifer from Ava. As soon as we're able to find her again."

"And we'll deal with this like we do everything," Castiel told her. "Together."

(Song:) Non, Je Ne Regrette Rien - Edith Piaf 

Dean, Ness and Amara nodded in agreement.

Sabrina turned to Catty and Castiel, tears in her eyes.

Catty, Castiel and Sabrina embraced.

Aiden looked at them, seeming to feel the somber and solemn mood, but not completely understanding it. 

Sam took a deep breath, looking exhausted and in denial and devastated at the thought of losing Ava, but determined to save her.
