Sam Winchester: Welcome to the team.

Gabriel: Uh...yeah. Not so much. I mean, thank you for the rescue and for the redemption arc. But, uh, I'm not really a team guy, so...I'm gonna bounce, okay? Um, but, you know, it's been, um... What's the opposite of fun? That.

Sam Winchester: No, Gabriel, don't... you... you can't just walk away. If Michael comes here, he will end this world.

Gabriel: And the last time the world was ending, I put my money on you. I think you can pull it off again.

Castiel: No. You cannot turn your back on your father's creation.

Gabriel: Castiel... my father turned his back on his creation. Guess it just runs in the family.
