Ciel: *sells soul*
Sebastian: Aww yeah, delicious depraved soul. This dinner is going to rock my world. It's going to be a cinch. Butlering's a cinch. Revenge? Easy as pie. Best deal I ever made.
Sebastian: *knows Ciel for 1 week*
Sebastian: I fucked up, I fucked up so hard. No soul is worth this aggravation.
