[First fanfic written. Please go easy on the newbie. Wrote this in a notepad. Filled it all. But I won't carry it on, unless people want me to. I won't bore you anymore if you think this sucks. I begun writing this just after the episode of 'You can't handle the truth' and the next episode trailer and carried it on from where I'd like it to have gone on to basically. Enjoy]

Dean dragged Sam's limp body over to the wooden chair and strapped him down. The betrayal and the anger he felt towards him, still made his gut twist in denial.

"You lied to me. You tricked me. How the hell do you expect me to treat you any differently to this?" Dean growled, grabbing some rope off the counter and tying his brother's wrists behind his back. Sam groaned as the friction bit into his skin. He wasn't aware of anything yet, but the pain in his face. He was sure a sledgehammer has been smashed into him at full force. His mind was like a dark haze, lingering and drifting away like a morning fog, until he suddenly relived the closest memory of Dean looming over him like a rabid animal, striking him over and over again. His fist pulling back, only to slam back down and his other hand, clutching his collar to wield him into the brutal attacks. He groaned again.

"D-Dean? What.. What are you doing?"

"I'm keeping my head in the case, Sammy." Dean replied coolly.

"Case?"

"You're the case, Sam. Actually - scratch that. You're my case."

Sam tested the wrist restraints and shot Dean, who was circling back round him, a hateful glare. The best he could muster in his battered state. "What are you talking about? I've already told you the truth. I told you the truth and you turned on me!"

"You told me you don't have any feelings. You can't feel remorse. You can't feel any fear. No guilt. And to me, that speaks nothing but a soulless- monster." He knew the harshness of the last word would burn him from the inside out. He watched as the overwhelming of pain flooded onto Sam's features.

"I'm not a monster. I'm Sam. Dean. You have to believe me. I told you for a reason - so you can help me find out what is wrong with me!" He winced as the wound on his lip split open again. "So maybe part of me got left behind in the cage somehow. I need you to want to help me. I want you to find the old me again. The Sam I once was."

Dean rubbed his eyes, tiredly. "This makes no sense. I called Cas down and he told me that you weren't Lucifer. You couldn't possibly be cus he couldn't feel it. Is he right?"

"Yeah."

"Or are you just saying that to please me?"

Sam sighed. "What do you want me to say? A lie? Yes, Dean. Lucifer is still inside me. That's why I've been acting so dysfunctional these last few weeks. Come on, man. If he was here, I'm pretty sure he'd of killed you by now. Untie me." He pleaded, giving a slight roll of his head to relieve the tightness in his neck.

"No." Dean said stubbornly. "Because even if you're not Lucifer. You aren't Sam either. And I can't take that risk of trusting you. And losing you all over again, in more ways than one."

"..I've lost something deep down. I haven't lost my mind. I'm not going to suddenly turn on you and ruin everything we've had!"

"YOU JUST HAVE, SAM!" Dean spat back with fury evident in his eyes. Sam didn't bite back. He grinded his teeth together in irritation and looked away. "..But even if there's just a speck of the real Sam left in there. You are still my brother. And I can't argue with that. So.." He lingered on whether to soften the tone. "-Come here and let me clean you up."

Sam turned back to look at him with an expression that only read; How exactly?

"I'm strapped down, remember?"

"Thanks for pointing that out, point dexter. I never would of guessed." Dean stepped round him and picked up a bucket of water he had prepared. He placed it at Sam's side and dragged the only other chair in front of him to seat himself. He then went on to rinse the cloth that had been floating in the water and pressed it against his brother's brow. He felt Sam wince from the stinging aid and grumble something under his breath.

"Sorry. What was that?"

"It's holy water. You're still testing me-"

"Yeah and shut up. It's for your own good.. How did you know it was holy water?"

"Cus I can smell it. It reeks. Mind reading aside though, Dean - that doesn't mean I'm a demon. See. My skin isn't burning." He rolled his eyes upwards to signal his bruised brow.

"Maybe we need to mix it up a notch." Dean smiled, reaching inside his pocket before Castiel intervened from out of thin air.

"Sam isn't to blame for this condition, Dean. Believe me, it's not his fault." The angel spoke calmly, less than an inch from his side. Dean flinched with unintentional dramatic effect and shielded himself instinctively. "Dammit Cas. Don't friggin do that again!" He blurted, catching his stalled breath.

Castiel looked nonchalant but averted his eyes guiltily. "Sorry, I'll try." He apologised. "..I'll cough next time." He coughed loudly into his ear, rendering Dean tense for a moment about the angel's sanity of normality. He looked at Sam, who looked back at him with the same old fashioned look.

"..Hello Cas." Dean mumbled.

"Dean. I need to exchange a secret with you in private."

"You're not going to confess your love for me, are you?" He teased. Castiel frowned,.

"No."

"Well then, it's as private as its going to get."

"Away from your brother."

Dean paused. "Is this about Sam?"

Castiel nodded slightly. Sam furrowed his brows together and Dean begun to lead the way to the small kitchen area in the next room. The angel followed, staring at the younger hunter with unease.

"He has no soul."

"What?"

"Your brother has no soul inside of his body."

"I heard you the first time but- How the hell has he lost it?"

"I believe becoming an ex-vessel of Lucifer can do that to you. Or render you dead. I'm not sure hoe he escaped the clutches of him or the cage but that is for when Sam wants to come clean. I suggest treading carefully around him. With no soul and bound to be pent up anger, he is going to be unstable. And having you right next to him when he's like that.. I don't think it's good for your health."

"Cas. He's my brother. He won't hurt me."

"Sam wouldn't agree with you on that." Castiel murmured. Nodding over to the door that held Sam behind it. Dean stared back at him hard and peered quickly round the side of the frame. Sam looked angered about something, but the swollen flesh covering his face, masked most of it.

"I can hear the two of you." He grumbled, just as Dean turned back to discuss further concerns with Castiel.

"Psst. Sam."

Sam froze, putting the voice to the face.

"Samuel? Is that you? What are you doing?

"Saving your ass from your brother - again. Keep quiet." And then he appeared from the hallway like a sweeping mist, briskly reaching for the restraints that held his grandson down. He could hear, as well as Sam, the conversation whispering next door. Sam rubbed his wrists and stood shakily to his feet. The room spun. He focused on the door Dean was just behind, deliberating whether to just follow Samuel's rescue or confront Dean without the weakness of being bound.

"I should really make him pay for what he's done to me."

"He will eventually. Just not now. Come on, we've gotta move." Samuel ordered, analysing the fact that Dean would glance into the room at any second and find them. Sam hesitated, sighed and then followed suite.
