Dean and Sam in “Unfinished Business”

Dean

So you're his vessel, huh? Lucifer's wearing you to the prom?

Sam

That's what he said.

Dean

Just when we thought you were out, they pull you back in, huh, Sammy?

Sam

So that's it, that's your response?

Dean

What are you looking for?

Sam

I don't know, uh, a little panic, maybe?

Dean

I guess I'm a little numb with the earth-shattering revelations at this point.
