Author's Note: The last part of this popped into my head, and I had to make up a beginning to go with it. I'm not completely happy with it, but it's the best I could come up with at the moment. Comments, reviews, and suggestions are read and greatly appreciated
Summary: Lucifer wants Sam to kill Dean. The hallucinations are driving him crazy. But who are they affecting the most?
Sam stood over Dean, ready to strike.
No! I won't. You're not real, Sam argued with the figment of his imagination. He was exasperated. Was this going to go on forever?
Lucifer ignored Sam's internal argument and urged him closer to his brother who was making no effort to defend himself against Sam's attack. Sam reached into his belt loop, and produced a knife. Staring at the gleaming metal before him, Lucifer teased him on in his sing-song voice. Only way to make it stop Sam. End him. End you. End it. Only way. Aren't you tired Sam? Tired of fighting? Fighting him? Fighting me? Fighting everything that wants to kill you, eat you, possess you. End it Sam, end it.
Sam struggled; a part of him wanted to listen, Lucifer's words just made so much sense, but another part of him, the part of him that would have given anything to help his brother, resisted the temptation to give in No he repeated weakly, but this time it was more to himself, a mantra no, no, no, no, no. just keep saying no. Dean needs you to keep saying no. Why isn't he even trying to talk me through this? Don't think. Just say no. no. He caught sight of Dean – worn out, and curled up in on himself Sam's resolve got slightly stronger. No he snarled.
Either way, you're still going to kill your brother
No! I will NOT! And with that Sam heaved the knife across the floor, chest heaving. It took him a moment to recompose himself. He looked down at Dean. He wasn't moving.
"Dean?"
There was no response. This can't be possible, Sam thought, I definitely didn't kill him.
"Dean!"
Still nothing.
Again, "Dean!" this time grabbing a hold of Dean's jacket and giving him a shake. There were only hollow eyes to greet him.
Sam reeled. He was trying to remember. Struggling to piece together what had happened. What had actually happened. As if hallucinations weren't bad enough, now his real memories weren't adding up. How crazy am I? What did I do? He assessed the situation. There was no blood, and the knife was safely across the room where he had flung it. He didn't remember knocking him out. What the fuck? Sam thought, getting extremely worried.
"Dean? Come on. Please? I don't even know what's wrong with you. You gotta give me something. Please?" Sam prattled on while checking Dean's pulse. He definitely had one. That was good. So what? Dean's in shock? That doesn't seem right. Sam looked down at Dean's perfectly healthy yet unresponsive body, the hollow eyes, the defeated aura, and Sam knew that Dean had retreated into himself – the only way to escape the physical pummeling, and the emotional trauma.
With that, Sam thought that Lucifer may be right, maybe he was slowly going to kill his brother. He sighed. I may be the one hallucinating hell, but Dean's the one who can't take it anymore.
