Sam's head heavily hit the opposing wall, he felt warm, fresh blood trickle down his face.
"You gonna give up Sammy? Are you?" the gruff voice of a possessed Dean Winchester echoed in his ear.
" Please, stop." Sam begged
"Why should I? It's all your fault, you know that. I only made that stupid deal so that i could come back and kill you."
" You're lying" cried Sam, blood coming down his face, staining his cheek and the wall
"Am I?" Dean applied even more pressure to Sam's now dislocated shoulder, "You're the liar, hiding Jess' death, I bet you saw dads too didn't you? But you still didn't save him, and you haven't saved me!" with that, Dean roughly pulled Sam to face him and crashed his fist into his jaw line and slowly backed away.

Sam woke up sweaty and tangled in his bed linen, breathing heavily. He glanced over at the other twin bed, Dean was sound asleep. It wasn't the first nightmare he'd ever had but it was the only one in which he'd seen his torturer, all the others had been the same, but he never knew who the other person was.
As he regained his breath he sunk back into his motel bed, only to jump straight back up when the most nauseating pain hit his head. He reached up to the spot only to feel something warm seeping out of a throbbing gash.
