After stopping off at a blood bank to stock up, Eden waited for the boys in the library, her duffel bag on the floor by her chair. She would've put it away, but was unsure as to where she'd be sleeping that night – something she'd inevitably have to awkwardly talk out with Sam.
When they did eventually get back, Eden was looking through the Genesis chapter in the Bible with a red marker in her right hand, mostly to keep from planning a way to tell the boys about Lucifer without putting Castiel at risk.
"It's laughable how much they got wrong in this thing. I've never really bothered to check – just heard little snippets from God-fearing morons." She chuckled to herself as Sam and Dean entered the library.
"Are you annotating the Bible?" Sam frowned, an amused smile on his face as he looked over her shoulder.
"Of course. Might as well correct it with actual facts from a reliable source." The girl shrugged. "Plus, I was bored waiting for you – needed something to keep my mind active. Can you believe they thought God created that whole Garden by himself? That crap took work, you know. How dare he take all my credit. They barely even mention my parents' kids and, of course, I'm not in it at all. I'll wonder how much effort God had to put in to erase his biggest mistake from the so-called history books. Funny they still called it 'the Garden of Eden', though."
"Alright, that's enough reading for you." Dean chuckled, taking the book from in front of her.
"I wasn't finished." Eden frowned.
"Yeah, you are." The older brother shook his head, unable to hide his smile as he put the book back on the shelf behind her. "Alright, I'm gunna crash for a few hours. I'm beat."
"Sleep well." Eden called as he headed towards the bedrooms.
"Did you wanna go and get some sleep too?" Sam asked.
Eden's brow raised.
"I... Don't need to sleep, remember?"
"Never stopped you before. Come on, you can at least keep me company." Sam nodded over in the direction of the bedrooms.
"Okay." Eden remained a little cautious. Why, she didn't really know. But she got up anyway, grabbing her duffel bag and taking his outstretched hand.
Not as much of an awkward conversation as she'd thought, apparently...

In Sam's bedroom, Eden got changed into a black silk, floor length night gown and matching robe, then sat on the bed over the top of the sheets with her legs outstretched. Sam got changed into a grey t-shirt and red and black plaid pyjama pants before crawling in under the sheets next to her. His head found a pillow in her lap as he hugged her legs.
Eden frowned at the notion, but draped her arm over his ribs, running a section of his t-shirt between her fingers nonchalantly.
"Goodnight, Elizabeth." He mumbled, already half asleep.
Clearly, he hadn't realised just how tired he was until he laid down.
Eden's brows raised, looking down at the side of his face that was exposed to her.
"Goodnight, Sam." She whispered, turning off the lamp next to her.
She rested her head back on the headboard and sighed, closing her eyes as her mind filled with way too many thoughts to keep track of.

The week following had been rather dull, mostly consisting of getting Eden settled back into the Bunker. Though, she had bought a piano to go in one of the rooms they never really used. That had quickly become her 'chill out room'. Since they brought it in, Eden had spent the majority of her time in there, especially when she didn't feel like sleeping. She spent the nights playing soft lullabies that echoed throughout the Bunker. The boys had quickly gotten used to that, so much so that it had helped them get a better night's sleep.
But the peace had to end at some point.
Sam was sat at the table in the kitchen with a pile of books in front of him. Eden was sat next to him with her legs draped over his thighs, sipping her glass of blood whilst she watched his face contort beautifully with thought and, on occasion, confusion.
She gave Dean a nod as he walked in, going to pour himself a cup of coffee.
"We're out." Sam informed him.
"There was half a bag yesterday." Dean huffed.
"I killed it." Sam replied.
"I tried to get him to go to bed, but he wasn't having it." Eden shrugged.
"Hey, did you know the Nazis had a special branch devoted to archaeology?" Sam interjected.
"Little early for Nazi trivia. Especially without caffeine." The older brother retorted.
"It was called the 'Ahnenerbe'. There were sites all over Germany and then, as the Nazis increased their territory, they started popping up in Poland, Finland, Africa..." Sam trailed off as Dean roamed the kitchen in search of something to wake him up.
"Yeah, how is this more important than our coffee situation?" Dean asked.
"Because I found something. I mean, we need something – magic, a weapon strong enough to give us a shot against Amara." The younger brother retorted. "So, I've been looking outside the lore in history, and I found this – 'The Vichy Memorandums'. They were Nazi communications that puzzled historians even to this day. They speak of a 'super weapon' obtained by the Ahnenerbe, said to be strong enough to win the war."
"Yeah? What was it?" Dean sighed, walking over to the pair.
Eden looked up at him with an amused expression, waiting for his face to change when Sam gave him the answer to his question.
"Well, uh, these memos refer to it as 'the Hand of God.' I mean, that was sort of a catchall term for several objects he touched on Earth in biblical times, but, they're believed to contain traces of his power." The younger brother said.
"Yeah, well, the Nazis believed a lot of things." Dean shrugged, walking away. "Besides, by that logic, doesn't that make Eden a 'Hand of God' too?"
"Mm, no. I was never touched by God. No, he couldn't bear to show his face to the child he imprisoned." Eden replied, sipping her blood.
"Dean, Lucifer's caged. God's MIA. The only beings strong enough to battle Amara are gone." Sam pressed. "If we're gunna fight her, then what better way to arm up than with an actual dose of his power?"
Eden looked down into her glass at the mention of the Devil as an awful wave of uneasiness overcame her. She didn't like how lying to the boys made her feel.
"Okay, so you said the Nazis got their hands on one of these... Uh, 'Hands'. Well, if it was so powerful it could win them the war, why didn't it?" Dean asked, grabbing Sam's empty coffee cup to drain the last drop into his mouth.
"Because they lost it. En route to Berlin, it was stolen. The Nazis searched high and low for the thief, but they never found their prime suspect. Uh, here. Delphine Seydoux." Sam replied, grabbing the correct book to show Dean a picture of her. "French mistress to a high-ranking Nazi. Thought to be a French traitor until she killed her German lover and made off with the weapon."
Eden pulled her legs out from Sam's lap and got up from her seat. After running her glass under the faucet, she headed towards the kitchen door.
"I'm going to go and get some more coffee to appease the beast that is Dean Winchester before he loses it entirely. Watching him get that last drop just now was genuinely painful. You boys... Debate what we're going to do today." She said, disappearing off down the hall towards the bedrooms.

Eden had gone a little overboard in her classically extravagant, classically Eden way.
She'd gone to Italy for the coffee.
She strolled back into the kitchen with two gigantic sacks of the best coffee beans Italy had to offer.
Sam and Dean glanced between each other.
"I thought you were going to the store." Dean commented, watching her place the sacks down at the end of the island counter.
"I was thinking about it, and then I thought 'hey, if I'm going out of my way to appease your need for caffeine, I might as well do it properly. So, these are courtesy of a rather pricey café in Florence." Eden replied.
"You went all the way to Italy just to get coffee?" Sam cocked a brow.
"Of course. I don't do things by halves, you know." The girl said. "Plus, it's not exactly like it costs me much effort."
The boys watched in slight awe as she ripped one of the sacks open and began the coffee-making routine.
Once done, the kitchen smelled of beautiful, high class coffee. She poured two cups and gave the boys one each, then stood back, waiting for their verdict.
"Oh, wow." Sam's brows raised.
"Damn, that's some good coffee." Dean groaned, savouring the taste. "I'm never gunna be able to drink the cheap stuff again..."
Eden smirked.
"Well, there's plenty more where that came from. So drink up and tell me what we're doing today." She said.
"Ah, yeah." Sam nodded, gulping down another mouthful of coffee. "That woman I was talking about earlier? Delphine Seydoux? Turns out, she was a French Woman of Letters."
"Interesting..." Eden narrowed her eyes, leaning the small of her back against the kitchen island as she crossed her arms.
"Let's go to the library, see if we can't dig up some more about what she did with the 'Hand.'" Sam said, getting up from his seat.

"Who knew the Men of Letters had a European chapter?" Dean commented as they scoured the shelves.
"Maybe it wasn't an entire chapter. Just some assets, you know?" Sam replied, looking through a book.
"I literally told you I was in the British Men of Letters chapter during one of our first conversations after I broke out of Heaven." Eden scowled at them. "It must be so frustrating having a Human memory span."
"Oh, yeah... I remember that." Sam nodded.
"There are chapters all over the world. Or, at least, there used to be. I know for a fact that the British chapter is still very fully operational and, if I've heard correctly, the Hong Kong one is too." Eden shrugged, skimming through all of the books the library had that weren't in English, but were relevant.
"Here you go." Sam spoke up, walking over to the centre of the room. "This report was written by Clifford Henshaw; a Bunker-based Man of Letters back in nineteen forty-three. It's the right era. But it's in French. Eden, you're up."
He placed the book down on the table, as Eden took a seat in front of it with the boys joining her.
"They're transcriptions from transatlantic cables between Clifford and Delphine." She said as her eyes scanned the pages. "They were making arrangements to get the artifact out of Europe to keep it safe. It starts by giving detailed information about the target – the Nazi officer Delphine killed. Mister Henshaw seems to have pulled some strings with a Man of Letters in the OSS to requisition an active US submarine to transport Delphine and the so-called 'Hand' back to America." She paused when she read the location. "Oh, wow, that's convenient..."
"What?" Dean asked.
"She and the artifact were to be sent back here - to the Bunker." Eden's brows raised.
"So, it's been here the whole time?" The older brother frowned.
"Hold up." Sam said, pulling out his laptop to type in a few things. "Uh, no. It never arrived. The USS Bluefin came under German attack midway through its trip across the Atlantic. The sub was sunk. The ship and its contents haven't been recovered to this day." He read, running a frustrated hand over his face as he leaned back in his chair. "Great. It's lost."
"Or is it?" Dean had a look of deep thought.
"Uh, yes... Tiny little bit." Eden frowned.
"Yeah, I'd say so. I mean, tides took the wreckage. Submersibles have been trying to locate it for years." Sam said. "I mean, if James Cameron and his Avatar billions can't find it..."
"Yeah, but... We have something James Cameron doesn't have." Dean smirked. Eden and Sam looked at him as though he'd finally cracked. "A friggin' Angel, guys. We have Cas."
"Great..." Eden sighed.
"What? Did you two have another falling out or something?" Dean asked.
"Something like that..." She mumbled. 
"Alright, well, suck it up, because we need him." The older brother said, whipping out his phone.

'Castiel' was round in no time.
Once explaining the situation to him, he got right to work, looking over everything they'd collected in the War room.
"There were several God-touched objects, but never occurred to me that any had survived the flood, let alone the twentieth century." He frowned.
"Do you think we can use it against Amara?" Sam asked from his spot on the library side of the map table.
"It's perfect." 'Cas' shrugged. The boys looked between each other. "I can get you back there."
"Without wings?" Sam frowned. "Cas, you can't even teleport."
"Yes, Pigeon. However will you achieve such a feat?" Eden smirked, leaning against the stair railing with her arms folded and a deep set glare.
"Time travel is a... It's a whole different system. Though, I may require Eden's help." 'Cas' explained.
"Told you." Dean looked to his brother, snapping his fingers.
"Look at the audacity on you. Asking me for help." Eden scoffed, shaking her head.
"I'm not asking for me, I'm asking for the fight against Amara." The Angel retorted with a warning scowl.
The brothers could feel the thick tension in the room, glancing at one another.
"Okay, whatever crap happened between you two, you need to fix it otherwise we're never going to defeat the Darkness." Dean huffed. "What the Hell did happen, anyways? You two were the closest you've ever been."
"Yes. Cas. What happened?" Eden cocked an eyebrow.
Everyone's attention turned to the Angel, who simply continued to focus his scowl on her.
"Nothing worth repeating. Isn't that right, Eden?" He said.
"If you say so." The girl mumbled.
'Castiel' moved to the evidence board behind him, looking over a few pieces of paper.
"So, uh, these the last co-ordinates?" He asked.
"That's the Bluefin's last transmission to shore, yeah." Dean nodded.
"Alright."
"Wait a second," Sam put a hand up. "Cas, aren't there still risks? With time travel? I mean, aren't there consequences that-"
"Sam," Dean dropped a flattened hand onto the map table. "This is the ideal scenario."
"What?" Sam scoffed.
"That sub's a tin can floating in the middle of the ocean, doomed to go down. You can't really mess with history at twenty thousand leagues. So we get in, get the weapon, get out. It's a milk run." The older brother shrugged.
"Well, that's not a very good plan." Sam retorted.
"If things get out of hand, then Cas'll just zap me right back." Dean told him, sitting back in his chair. "Besides, my plan with you and Eden was a bad one, but that still worked out."
"Getting Eden and I to make up is a world away from going back in time to get an artifact. And what do you mean 'you?'" The younger brother frowned.
"You're not going." Dean said.
"I beg your pardon?" Sam sat forward in his chair, resting his forearms on the map table.
"You need to stay here."
"Stay here?"
"Just in case things go sideways , somebody needs to be left standing to help take care of the Darkness." Dean raised his voice. "We can't risk us both. At the moment, I'm the least valuable player. You all know that I can't kill Amara, so the least I could do is get the thing that we need so that you can!"
"So you expect me to sit here and ride the pine while you, Cas and Eden go play Jules Verne?" Sam scoffed.
"Yes! No... Who?" Dean frowned in confusion.
"I won't let him out of my sight." 'Cas' ensured.
"The Hell you won't." Eden spat.
'Cas' looked up at her and smirked.
"Eden, would you rather I go with you and Dean or stay here with Sam, just the two of us?"
Eden's eyes darkened. This was one Hell of a catch-twenty-two situation...
"What the Hell does 'just the two of us' mean?" Dean asked.
"Nevermind." Eden said through gritted teeth.
"You'll stay by his side the entire time?" Sam conferred with the Angel.
"I will." 'Cas' nodded.
"Sam," Dean sighed. "Let me do this. Okay? I need to do this."
Whilst neither brother was looking at him, 'Cas' had a smirk on his face that put Eden so on edge, she was afraid she'd fall off.
"Be safe." Sam mumbled.
"When am I not?" Dean shook his head, earning a scoff from his brother. "Let's do this, guys."
Dean rose from his seat as 'Castiel' and Eden walked over to him.
"Bon voyage." The older brother shrugged to his sibling.
'Cas' took his shoulder and Eden's and then disappeared... Leaving Eden behind.
"You fu- son of a WHORE!" Eden screamed in the direction in which 'Cas' had been standing. "I am going to kill that feathered little-"
"Hey! Hey, hey, hey." Sam quickly walked over to her, holding her by her upper arms. "Why'd he leave you? I thought he needed to channel you or whatever to get there and back."
"Yes, so did I." Eden growled through gritted teeth.
"You can't be so pissed at each other that he'd risk getting himself and Dean stranded in the forties just to leave you behind." Sam frowned. "Seriously, Eden, what's going on with you two?"
"I don't want to talk about it..." She mumbled, glaring at the floor to her right.
Sam huffed, using the side of his index finger to re-direct her gaze to him.
"Whatever it is, Cas thought it was bad enough to risk Dean's life over it. So we're gunna stand here until you tell me." He said.
"No, we're bloody not." Eden argued, shaking his hands off her arms to walk away.
"Eden, get back here. Don't you walk away from me." Sam snapped.
The girl spun around to face him with an expression of rage.
"Let's get one thing straight here, Sam. No one. Not even you, can tell me what to do. What's going on between Castiel and I is none of your bloody business. So drop it." She spat.
"It is my business when my brother's life has just been risked over it!" Sam shouted.
"I can't tell you, alright? I just can't. If I do, bad things will happen. You're just going to have to trust me." Eden told him just as someone walked through the Bunker door.
The pair looked up, seeing a soaking wet 'Castiel' trudging his way down the stairs, dripping water through the grates in the steps.
"Cas?" Sam frowned. "Why- wait a second, where's Dean?"
"We made the leap." 'Cas' replied looking less than impressed. "He got on, I didn't."
"That probably wouldn't have happened if you'd have taken me with you." Eden sneered. "If anyone needs me, I'll be at the piano."
With that, she stormed out of the War room and down the corridor, slamming the piano room's door so hard, it made Sam jump. The wood in the door even cracked a little bit.
"What happened?" Sam asked the Angel as the sound of lively, eccentric piano music echoed throughout the Bunker.
"I couldn't make it passed the hull." 'Castiel' told him, walking into the library as he removed his trench coat. "Someone must have warded the ship."
"Delphine. It has to be." Sam shrugged, following him. "I mean, she's protecting the weapon, right? Cas, just go back to their last port before she boarded, leave a message so Dean knows."
"Where?" The Angel looked at him in spite as he towel dried his suit. "Where would Dean see it that the crew wouldn't? He's as likely to find the warding as he is any message I'd leave."
"Then send me. You got Dean passed the hull." Sam suggested.
"Right. We'll double-down on what screwed us the first time." 'Cas' retorted, his voice thick with sarcasm. "You're really bringing your 'A' ideas today... I can't believe I lost it- him." He huffed, sitting down in one of the library chairs. "Mm. Can't believe I lost Dean. Well, it's up to him now to find and clear the warding."
"No. We can help." Sam held up a finger, wandering over to the book shelves on his side of the room. "There's gotta be something in – in magic or Angel lore. You know, maybe some way to clear the sigils from the outside. Or maybe Eden can go, you know, since she's not technically an Angel in your kinda sense. She's a different kind, maybe she needs different warding to be kept out of places."
"She looked pretty mad back there. Do you really want to risk being wrong and see her come back soaking wet and even more mad?" 'Cas' cocked a brow.
"I think she'd rather see Dean back safe and risk getting a little wet than staying behind, locking herself away, playing angry piano music." Sam retorted. 'Cas' wiped a hand down his face in frustration. "Don't worry. We'll bring him back."
Sam placed a book he'd found down on the table, opening it up to start researching.
