Chapter song: Somebody that I Used To Know- Gotye

"He's known." Dean swore ripping the postcard to shreds right before Cas' eyes. "This whole fucking time, he's known exactly where we were."

"I..." Cas trailed off staring at the tiny pieces of paper as they fluttered to the ground. A twinge of sorrow tugged at his heartstrings, the postcard both terrified him and gave him a glimmer of hope that someone out there might have given a damn about him. "You have to tell him now, about Sam."

"Bull."

"You've given him this delusion that Sam was some kind of martyr, you need to tell him that Sam failed or nothing will change."

Dean looked down at Cas, he felt naked under the cold gaze and drew his knees up to his chest. "You really think he can change anything?"

"No, I know you've always been to stubborn to listen to anyone else. He won't say yes to Michael, because Castiel won't let him, but that doesn't mean he can't find loopholes that will prevent all of this."

"All of this huh? Wow you make it sound like you're not happy here." Dean snorted. Cas pushed pieces of his broken Buddha across the floor, if this were any other day he'd have some sarcastic retort but this is the day he's reminded that he's completely venerable and easily killed.

"I think you wanted to love me, you wanted to be able to hold on to something human. And now every time you look at me you're reminded how not human you are." Dean stopped passing, he looked at Cas his eyes wide in shock. The look didn't surprise Cas because he hadn't called Dean out on his shit in years.

"Cas, everybody knows." Dean tried to keep his voice steady but it broke slightly, Cas wasn't sure if it was from shock or anger "Everybody knows about us. How could they not after that huge fucking scene that damn kid made…but that's what you wanted wasn't it? You wanted people to know, now they do."

"I always thought…I always thought that if it stopped being this secret thing we did behind doors then it would mean you and I actually had something. I prayed for it, for years, and now I realize I can't ask you for something you could never give me."

Dean looked away, Cas caught the quickest flash of something, guilt, pain, something he had seen on Dean's face since he first heard about Sam. All he wanted to do was beg him to stay and tell him it was all going to be okay but that wasn't the kind of thing his Dean did. So for the second time that day he just let Dean walk out of his life.

The news of the postcard had spread all over camp, everyone was whispering and trying not to panic. All this time they hadn't really been safe, they just hadn't been important enough to kill. Dean was sure Cas was teetering on the edge but Dean hadn't ever begged or crawled back to anyone before and he wasn't planning on starting now.

Besides he's just won a staring contest with his self and been rewarded with the truth. The devil's wearing Sam like a fucking Halloween mask. And of course the only person that could ever leave Dean Winchester speechless was Dean Winchester. Then he was alone in the cabin trying to wrap his head around that, he'd barely flinched when he was told Sam was dead because the brothers died all the time and all he had to do was be there for the showdown because as long as they stuck together everything would be okay. But this was so far off the radar, it wasn't Sam being misled and tricked, it was Sam willingly saying yes to Lucifer. How was Dean supposed to deal with that?

"He told you." Dean didn't turn to look at Cas when the doors closed, only stared blankly ahead, curled up with his back against the wall. "I am sorry."

He sounded so formal if it weren't for the searing pain in Dean's chest he might have thought he was back in 2009. Dean wasn't sure if he was apologizing for the bloody wound on the back of his head or for lying to him the past few weeks.

"Leave." Dean croaked out.

"Dean said we can't continue to live under the devil's eye. He said we need a plan." Cas took a shaky breath. "And when we have one, we will go out and kill our brother."

Dean flinched, our brother because now Lucifer and Sam were the same, they couldn't be separated and it was all over. Cas took slow steps over to the hunter, Dean heard the crumple of plastic and glanced over just enough to see a dull yellow bag gripped tightly in his hand.

"You're not him Dean and it doesn't have to end like this." Dean didn't think Cas actually believed any of that, it was all a poor attempt to comfort Dean or maybe Cas was trying to get back in his good graces.

"Not now Cas, just…not now."

"You once told me words are cheap." Cas dropped the bag by Dean's hip, it's contents rattled and some spilled out, one rolled all the way to Dean's feet. He looked down, saw the yellow bottle and the pink pills inside.

"Cas?" Dean asked.

"I don't need these." The way he said it, in a way that Dean's sure Cas wanted to add That's stupid of course I need them, give them back. Cas shifted from foot to foot forcing himself to look away from the scattered bottles on the floor as Dean packed them back into the yellow bag. "May I sit with you?"

A part of Dean nagged at him that the bag was only half full and there was probably still dozens of bottles all over camp. It was a start though. Dean shrugged his shoulders and the ex angel sat down next to him. He felt like he should say something, yell that this is all a bad dream and Sam would never actually agree to be the devils meat suit.

Cas doesn't say anything either, as much as he wanted to because whatever he said might throw Dean into a homicidal rage. I know he's an evil, lying, manipulative son of a bitch that I never really liked but he's still my brother, the only family I have in the entire universe. And now, some how I feel like Lucifer was the only one that gave a damn, maybe he allowed this whole camp to exist for me and it's not his fault you turned out to be such a let down.

Of course he'll never say that and in a few hours he'll be back to blindly following their fearless leader. "He just couldn't handle it, when Sam left he barely held on, then one day he just shut down."

"I can't do it Cas." Dean nearly chocked out. "Sammy's all I got, and I don't care if he's the ten year old brat from before or the king of Hell he is now, I can't kill my own brother."

"I know. You won't have to."

"He won't do it either, he can't- no one changes that much. It doesn't matter how different you think I am here he won't be able to kill Sam."

"He's not you anymore and that's not Sam."

"Trust me, it won't matter." Cas gave Dean a hard look almost as if he was seeing him for the first time.

"I forgot how hopeful you used to be." Dean had been called a lot of things but hopeful was certainly never one them. "It's weird."

"What is?"

"This gap between who you are and who I remember you being, I suppose that's what happens when you put someone high up on a pedestal." Cas let out a chuckle, soft and slightly bitter. "Being so young I'm sure you won't understand the reference. But really, you're just somebody that I used to know."

So I apologize that this is short, I'm half-way through a chapter from another story when I realized it's been Forever since I've updated this. So I wanted to write out a quick chapter so there wouldn't be to long a wait till I write a real chapter.

Enjoy! Reviews always make me giddy :P.
