Sam Winchester (to Dean): I'm the one who brought him back, and I brought him back because he's family. And then he came back, and he burned his soul off to save us... you and me. And now what? You... Now you... you want my permission? You want me to say I'm cool with losing him and losing you all at once? 'Cause I can't do that. I won't say that, 'cause I... No. I've already lost too much.
