Sam Winchester: What's the catch? What do you want?

Arthur Ketch: Protection. From Asmodeus.

Dean Winchester: The one you're working for?

Arthur Ketch: Was working for. When he finds out that I stole his prize milk cow, well, I imagine that he'll hunt me to the ends of the Earth. So... this is the only safe place I know.

Sam Winchester: What? Do you think you're just gonna move in?

Arthur Ketch: Dibs on the top bunk?
