Frozen in fearful awe, I watch as my brother exorcises the poweful demon Sam Hain with his mind, one hand out and the other to his temple in obvious agony as he does. Sam glanced at me, but did he see me? I don't ask as I help him out of the tomb and back to the Impala in silence. Sam's pale, but at least his nose has stopped bleeding.

That night, I'm jolted awake by Sam calling out for her, RUBY, in his fitful sleep. I freeze again, terrified that he's already slipped down that slope into her arms and everything else unholy. I continue to listen and hear his breathing slow.

"Dean? You awake?" Sam asks a moment later, doing a near perfect job of keeping the anxiety out of his voice.

"Yeah," I reply into the darkness.

"I'm sorry. I really did try to use the knife," he apolgizes.

"I know," I acknowledge after a quiet sigh of relief, despite our father's words echoing in my mind.

"If you can't save him, you'll have to kill him."

"We'll get through this together, okay?" I say, unsure if the words are meant to reassure him or me.

"Good," Sam mumbles.

Please, God, I wish before I too begin to drift back to sleep, don't make it come to that. I can't do it. I won't.
