THE BUNKER

In the bunker library Sam and Elena is still hard at work searching for another way. In frustration, Sam slams a book shut and shoves it off the table.

"Sorry." Sam Says

"It's alright. I understand it. I-I... I feel it, too. It's hopelessness." Elena Says

"Maybe Dean was right." Sam Says

"Yeah, maybe." Elena Says

Cas enters, picks up the book, and returns it to the pile on the table.

"Here you go." Castiel Says

"Thanks, It just... It feels wrong. You know, Billie's got Dean so convinced." Sam Says

"But you don't believe her?" Elena Asks

"I don't know what I believe. I just wish I could talk to her, Billie, before it all goes down, you know, just to make sure." Sam Says

"There is no easy way to summon death, and I will not let you end your own life." Castiel Says

"Cas, that's not what I'm saying. Wait...You remember when Sergei was here? Remember what he was looking for?" Sam Says

"Yeah, it was the Key to Death." Castiel Says

"Yes." Sam Says

"Wait, he said it would open the doorway to—to Death's Library." Castiel Says

"Wait seriously?" Elena Says

"Yeah but If it's in the bunker and if we can find it, m-maybe I can just...walk up to her, right?" Sam Says

"Right." Castiel Says

"Let's start looking." Elena Says

Soon there's a montage of Sam, Elena and Cas researching the key and looking through boxes of artifacts.

In a chest labeled "Copper Creek Mining Company," Elena finds a casket with the skull symbol from their research. Inside is the key they're looking for.

"Cas..Sam?" Elena Says

"Cas, this has to be it." Sam Says

Elena hands Sam the box, then looks inside it.
"Wait there's an inscription."

"It's in Latin. Viator mortalis, cave, quoniam scias Clavem Mortis pensare graviter. Il tamen desideres, ut introeas illum abyssum obscurissium artis, opus est tibi porta." Sam Says

The key glows in Sam's hand, and the illuminated outline of a doorway appears on the wall, with a glowing keyhole.

"Sam, Elena I should go with you." Castiel Says

"No, Cas... Look, I don't know if this is crazy or...or what, but if Dean beats us back here...Buy us some time?" Sam Says

"Look, for what it's worth, I don't think you're crazy. I think your internal compass is functioning perfectly." Castiel Says

Sam looks to Elena, "Ready?"

"Yeah." Elena nods, as Sam nods as well.

DEATH'S LIBRARY

Sam puts the key into the hole and, he and Elena goes through the doorway into Billie's library. They are then confronted by the body of a reaper on the ground, and then more dead reapers. In the distance they can hear screaming and cautiously explores.

"Please! Wait, wait, don't hurt me! No!"

"Please, please. She won't come!"

"Keep praying or whatever." The Empty Says

"It's hopeless! Please! O-Okay, okay, okay." He prays, and nothing happens, "I told you."

The Empty twists her hand and the reaper dies. Sam and Elena attempts to sneak away, but it's too late. She snaps her fingers and the two of them is suddenly in front of her.

"Sam and Elena Winchester?" The Empty Says

"Meg?" Elena and Sam Says

"Sorry, she's still dead. Just borrowing the Queen's pretty face 'cause really, I'm Empty."

"You're the Empty?" Sam Says

"That's what I said." The Empty Says

"What are you doing here?" Sam Asks

"Death and me need a word. Been trying her party-line, but she's ignoring me. I hate that." The Empty Says

"What do you want?" Elena Asks

"The Empty was supposed to be mine. Not even God held sway. But lies, sweet little lies. Billie said when she takes over, she'd make it all better, but then your busted-ass friend in the trench coat came along and he gave me these trust issues." The Empty Says

"Billie wants to take over?" Elena Says

"Become "New God." Classic narcissist, right? She's all tingly for the rules, the good-old days." The Empty Says

"What is that supposed to mean?" Sam Asks

"Everyone back to where they belong...realities, dimensions, graves. What should be dead dies, angels off Earth, demons back to Hell, and I go back to sleep. Or I'm supposed to. Except, again, trust issues. But you, Sam and Elena Winchester. You're in God's book." The Empty Says, then taps the thick book on Billie's desk.

"That's... That's Chuck's Death Book? Have you read it?" Sam Asks

"Only Billie can read it, dummy. She always talked about how you should be so dead, except she needs you. So, maybe if I hurt you..." She holds up a hand and makes a fist, Sam and Elena crumples in pain and groans, "Hear that? Get your scythe down here, Billie, or your boy and girl's toast." The Empty Says

"Wait! Stop! Billie sent us.." Sam Says

The empty releases her grip on Sam and Elena, then raised a brow. "She did what now?"

"Billie..." Elena looks to him confused, he looks to her as he thinks quickly, "She sent us." Sam Says

"Really?" The Empty Says

"Yeah..she did." Elena Says

"I don't know 'cause you're saying a lot of dumb stuff for, you know, an Emissary of Death." The Empty Says

"Yeah. We're all... We're trying to beat God. Not a whole lot of time for questions." Sam Says

"Go on." The Empty Says

"Billie... sent me... to get the book. She didn't say why." Sam Says

"Where is she?" The Empty Asks

"Earth. You can't go there, can you?" Elena Asks

"Only if I'm summoned. God's so protective of his little sand castles." The Empty Says

"Well, Billie can't leave, either, something about the plan, so she sent me and Sam with a message. Billie will honor her promise. God, Amara..they die. And you, you can go back to sleep." Elena Says

"And if you're lying?" The Empty Says

"I guess you have two choices. Give me the book maybe we all win. But you kill me, we lose... And you will never go back to sleep." Sam Says

Sam and Elena suddenly returns through the door into the bunker's storeroom, bringing Chuck's Death Book with them.

"Cas." Sam Says

"Sam, Elena finally." Castiel Says

"What? What's going on?" Elena Asks

"It's Amara. She's here with Chuck. It's time." Castiel Says

"No, no, no. Cas, we can't let that happen. We have to stop it." Sam Says

THE BUNKER

Meanwhile in the room that Amara has trapped Chuck in, he's pacing back and forth.

"It's not too late, brother. You can still choose this world, us. It doesn't have to end like this. I--" Amara Says

"Amara. Shut up." Chuck Says

Amara looks to him then shakes her head, while Sam and Elena tries to explain everything to Castiel in the library.

"Chuck and Amara cannot die." Sam Says

"Wait, I don't understand." Castiel Says

Dean enters, supporting Jack who is doubling over and clutching his stomach.

"Are they ready? We need to get this kid in the room right now." Dean Says

"Wait, wait... Dean... Dean, no. Listen!" Elena Says

Back in the room where Chuck and Amara are, he lifts his head up.

"You hear that?" Chuck Says

"What?" Amara Says

"Dean. Brought to the edge of doubt. His sense of duty, his rage winning out in the end." Chuck Says

Back in the Library, Dean helps Jack through the halls while Elena, Sam and Cas follow.

"Dean Billie is playing us." Elena Says

"So, what, her plan's not gonna work?" Dean Asks

"No, it will work." Elena Says

"Then great." Dean Says

"But listen, if Jack takes out God and Amara, it'll create a power vacuum that Billie will fill. This was all her power grab." Sam Says

"Wait, Death wants to become God?" Castiel Says

"Yes!" Sam and Elena Says

"As long as Chuck dies, I'm good." Dean Says

"Okay, listen, just stop." Sam Says, as he circles around in front of Dean, blocking the way.

"Get outta the way, Sam. What are you doing?!" Dean Says

"I'm trying to make you listen." Sam Says

In the storage room with Chuck and Amara, he starts chuckling.

"And poor Sam. Always gotta know everything. Can't leave well enough alone." Chuck Says

"We don't have time! Jack already lit the fuse! We gotta go!" Dean Says

"You did what?" Castiel Says

"I'm sorry." Jack Says

"Sam, I'm not gonna ask you again." Dean Says

"Dean, please." Sam Says

"This is my ending. My real ending." Chuck Says, as Amara looks confused.

In the hallway Dean pulls out his gun and aiming it at Sam.

"Move." Dean Says

"Dean, don't." Elena Says

"Move, Sam. Move!" Dean Says

"You orchestrated this?" Amara Says

"What part of omniscient do you people not understand? So I can't read my "Death Book." So what? I control space and time. Just plant a few visions, goad Death a little... Mess with a few outcomes... And... bada-bing! I mean..they think they can kill me?" Chuck Says, laughing.

"Dean, don't do this." Elena Says

"I don't want to do this, but this is everything!" Dean Says

"No, it's not!" Sam Says

In the storage room Amara shakes her head, then looks back over at him.

"They're not going to kill you. They're going to cage you." Amara Says

"Oh, sis..." Chuck Says

Dean cocks his gun still aiming it at Sam, "Get outta my way."

Sam shakes his head then bats Dean's arm to the side and they struggle. Dean then punches Sam in the face getting him out the way.

"They want to kill me. And... they want to kill you. There's no cage. There never was." Chuck Says

Dean carries on hurrying Jack toward the storeroom,
"Let's go, let's go."

Elena kneels down to Sam he motions for her to go on.

"Stop him." Sam Says

Elena jogs down the hall and gets in front of Dean, he sighs in annoyance.

"Dean. No, Dean stop please." Elena Says

"Lena get out of the way, now!" Dean Says

"I'm not moving, and you can't make me." Elena Says

Dean shakes his head and lunged at her, but Elena dodged and punched him in the face and he long with Jack tumbles to the floor.

"Sam and Dean, they're using Jack to destroy us." Chuck Says

"No, but... but Dean can't hurt me." Amara Says

"No, but he can lie to you. He could send you into the meat grinder with a wink and a smile." Chuck Says

Back in the hallway Dean spits out some blood, as Cas attends to Jack who's still in pain.

"You guys go, go!" Dean Says

"Jack, don't!" Elena Says

"Elena, why not?" Castiel Asks

"Because if Billie takes over, then everyone goes back to where they belong. That means everybody from apocalypse world, Bobby, Marley, Charlie, they get sent back to a place that doesn't exist anymore." Elena Says

"And everyone we saved. Eileen, she...she just dies again. And that's just the beginning Dean." Sam Says

"Look, I get it. You wanted him to care about you, but humans... they'll break your heart every time." Chuck Says, as Amara looks hurt.

"Elena, we don't have a choice. Jack's about to blow!" Dean Says

"Dean we always have a choice." Elena Says

"I spent so long searching for happiness, contentedness. In creation..or the Winchesters. But the only ones who will ever really "get" us... is us. You and me. Back together?" Chuck Says

"There's nothing else we can do, okay?! We just gotta get out of the way." Dean Says

"No, we can't get out of the way, Dean, not this time." Sam Says

"I don't care if Billie gets what she wants! I don't, man! I'd trade it all—I'd trade 'em all for Chuck in a heartbeat!" Dean Says

"What about us?," Dean turns to her, "Would you trade us?" Elena Says, slowly approaching him.

"Balance." Amara Says, looking to her brother.

"Yes. Think of it. Us starting fresh. Creating something new, something beautiful...peaceful... together. And we can finally forget about all this pain. No baggage. Only balance." Chuck Says

Chuck extends a hand to Amara. Tearful, she takes it and is absorbed into him. One of his eyes glows blue, and the other black.

"Chuck has to die. He has to! Otherwise he'll keep us tap dancing forever, and I can't live like that, I can't live like that! I won't!" Dean Says, tearfully.

"I know you feel like that right now, okay. I know you do. But you gotta trust me and Sam. Your entire life, you've protected Sam, you've protected me, from Lucifer, Michael, from everything. I didn't always like it, you know, but..it's the one thing in the whole world that I could always count on. It's the only thing I've ever known that was true. So please...put the gun away. Just put it away, and we'll figure it out, Dean, we'll find another way, you and me. We always do." Elena Says, with tears in her eyes.

Dean uncocks the gun and puts it away. Meanwhile, the door to the storeroom explodes and Chuck/Amara comes storming out.

"Are you kidding me?! After everything, all that, you...you did it again!" Chuck Says

"Where's Amara?" Castiel Asks

"Amara. Amara. She's in here somewhere." Chuck Says

"What, you consumed your sister?" Castiel Says

"We came to an understanding, so spare me your contempt, Castiel, the self-hating angel of Thursday. You know what every other version of you did after "gripping him tight and raising him from perdition?" They did what they were told. But not you. Not the "one off the line with a crack in his chassis." All of you. You know, I tried and I tried and I tried, but you're all just too stupid, too stubborn. Too broken. You know what? I'm over it. I'm over you." Chuck Says

"Yeah? Good." Sam Says

"Screw you, Chuck." Dean Says

"No, screw you. You know what you do with broken toys? You throw them out. So, kill each other, don't kill each other... I don't care." Chuck Says

"What do you mean?" Elena Says

"I mean... have fun watching him die." Chuck Says

Chuck points at Jack, who doubles over in pain.

"Jack." Castiel Says

"Help me!" Jack Says

"Jack, Jack, Jack." They all say

Jack's eyes glow gold, and golden light breaks through cracks in his skin.

DEAN: Jack!
