He knows. He knows it too damn well. But if it saves Sam, he'll take that look of betrayal and he'll just be damned all over again. Not like he really deserves any better, right?

He shook his head, a wry smile coming to his lips. "Yeah, okay, Sammy."

He tries to pretend this doesn't hurt, that he's not sick with himself. He doesn't try to pretend Sam probably won't hate him... at least for a while anyway. Nobody can hold a grudge like that kid. "I don't really give a crap right now if it stops you from becoming something you don't really want to be, Sam. I know you. You don't have to stay around me, but you're not touching demon blood again. Got it?"
