Roger Sterling: What you did is totally unacceptable.
Pete Campbell: I realize that.
Roger Sterling: I want you to be very clear about this: You were fired. I wanted you out. Cooper wanted you out. And you would be...if it weren't for this man. (motions to Don) He thought you deserved another chance. That's right. He fought for you.
Pete Campbell: I don't know what to say.
Roger Sterling: Say nothing. You are here because of Don Draper's largess.
Pete Campbell: Thank you. Thank you so much.
Roger Sterling: Now, I know that your generation went to college instead of serving, so I'll illuminate you. This man is your commanding officer. You live and die in his shadow. Understood?
Pete Campbell: (nods vigorously) I won't let you down, Don.
Roger Sterling: Jesus! Campbell...don't ever say that.
