[It takes Lucifer a world of effort not to roll his eyes at the conversation from the corridor. Really, he should be given an award for it. Sammy's good, but it's not the Sam he's wanting — he wants the angry one, the one tainted and powerful and compliant. He wants the boy with the demon blood he'd personally shaped.

And anyway, family is a sham. Family turns on you. Family drives a spear through your very being for daring to think differently about humans — the equivalent of ants being fumigated.]

[His voice is soft, as if his heart aches for the boy.]

You think Sam and Dean haven't killed? Caused deaths? They're hunters, Jack. They spent a lot of their lives killing beings without even knowing if they were actually deserving of death. But... it doesn't make someone evil to have to kill. Nothing is ever so gray.

I'm afraid my time is running thin; Sam is having a nightmare, and I really should get back in time to soothe it.
