[Dean turns at the sound of the familiar voice, wondering what Sam's doing here before figuring it must be some dream version of his brother, probably trying to teach him an important moral lesson, or however the hell his subconscious works these days.
Except, when Dean sees him, he knows it's not Sam; the white suit, for one, and the hair, for another. He stiffens. Even after older Sam explained how Lucifer was possessing this version of Sam, Dean didn't exactly fully believe him; he remembers, still, all the demons gossiping in the Pit, talking about Lucifer the way human Christians talk about God. And Dean has never believed in God, despite the fact that, according to Cas, God has work for him to do, so why should he believe in the devil, either?]

[If this has to happen, you're damn right Dean's going to be quoting the Stones.]
What could possibly go wrong?
