Grey's Anatomy, Season 8

[Mark interrupts Derek, who is analyzing a patient's scans]

Mark:
Hey, you got a second?

Derek:
Wait just one second.

Mark:
I'm a little worried about Avery.

Derek:
[tries to ignore him] I'm--I'm this close to getting this.

Mark:
We had a real connection, you know?

Derek:
[puts away his notes and looks at Mark] Okay.

Mark:
Well, we were having such a good time together, and suddenly he's avoiding me. He's cold and distant.

Derek:
Well, you're afraid 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. And I, you know, I just-- I want to see him do well. Maybe I just need to back off.

[Owen enters the room]

Derek:
Ah, Hunt. Just in time. Mark is afraid that Avery is gonna break up with him.

Mark:
Can this just stay between you and me?

Owen:
[awkwardly] I'd prefer that. Uh, Shepherd, about these cases--

Derek:
I know what you're gonna say. You're worried about the hospital's 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 you say no enough, you're gonna hate yourself, which is why I'm not gonna watch you go through this. I have a consult. [looks at Mark] If you love someone, set them free. If they come back.. [facetiously blows a kiss to him]

[Derek quickly leaves the room]

Mark:
I'm gonna punch you. [to Owen] Hey, let me ask you something––

Owen:
No.
