Castiel: Uriel's the funniest Angel in the garrison. Ask anyone.
Dean: Cas, hold up. What were te going to tell me?

Dean: Destiny? Don't give me that "holy" crap. Destiny, God's plan... It's all a bunch of lies, te poor, stupid son of a b*tch! It's just a way for your bosses to keep me and keep te in line! te know what's real? People, families - that's real. And you're gonna watch them all burn?
Castiel: What is worth saving?! I see nothing but pain here. I see inside you. I see your guilt, your anger, confusion... In Paradise all is forgiven. You'll be at peace. Even with Sam.
Castiel: I dragged te out of hell, I can throw te back in.

Castiel: No, he's not on any flatbread.
Raphael: I will find you!
Castiel: Maybe so, but today you're my little b*tch.
