Dean: Look, pal, I’m not buying what you’re selling. Who are you really?
Castiel: I told you.
Dean: Right. And why would an angel rescue me from Hell?
Castiel: Good things do happen, Dean.
Dean: Not in my experience.
Castiel: What’s the matter? You don’t think you deserve to be saved.
Dean: Why’d you do it?
Castiel: Because God commanded it. Because we have work for you.
