Sam Winchester : [after Dean has almost killed himself to convince Billie to let Sam go in exchange for Dean's soul] Hey, so - what did you do? When you thought I was dead. What did you do?
Dean Winchester : Thought about redecorating your room, y'know? Putting in a jacuzzi, a nice discoball - really class up the joint.
Sam Winchester : Right. Seriously.
Dean Winchester : What. I uh - I knew you weren't dead.
