Brady: Maybe you should be a little less worried about our necks and be a little more worried about yours.

Crowley: Has crossed my mind. That's not really the point.

Brady: Actually, Crowley, that is the point. No one will know greater torment than you. Lucifer is never gonna let you die. As for me, I know the score. I'm dead, whether I tell you anything or not. So I think I'll die on the winning side, thanks.

Crowley: Good talk. Cheers.
