Castiel and Dean in “Unfinished Business”

Castiel

The first blade is back in play and Crowley is the one getting it? I don’t mean to be an alarmist but...

Dean

Yeah well you know us, when we screw ourselves, we like to go whole hog.

Castiel

This would be the Crowley who let the blade turn Dean into a demon?

Dean

I don't have a choice, okay. I don't do this I'm down the rabbit hole; hear evil, see evil, do evil - the trifecta.
