Mark: Hey, you got a second?
Derek: Wait just one second.
Mark: I'm a little worried about Avery.
Derek: I'm this close to getting this--
Mark: We had a real connection, y'know?
Derek: Okay. (sighs)
Mark: We were having such a good time together. And suddenly, he's avoiding me. He's cold, distant.
Derek: Well, you're afraid that you're about to have your heart broken by him.
Mark: Kind of. Derek, you know me. I never gave a crap about teaching in my life but lately I like the idea of passing it on. Y'know, I- I just want to see him do well. Maybe I should just back off.
Derek (to Owen who walks in): Ah, Hunt, just in time. Mark is afraid that Avery is gonna break up with him?
Mark: Can't this just stay between you and me?
Owen: I prefer that. Shepherd, about these cases--
Derek: I know what you're going to say. You're worried about the hospitals mortality rate going up, see that's the worst part about being chief. You have to say no to everybody, and they hate you for it. And if you say no enough, you're gonna hate yourself. Which is why I'm not gonna let you go through this. (to Mark) I have a consult. If you love someone, set them free, if they come back... (kisses his own hand)
Mark: I'm gonna punch you. (to Owen) Hey, can I ask you somethin'?
