Grey's Anatomy, Season 8

Mark:
Derek! You're trying to steal my guy. He's my guy. Avery go get in the car.

Jackson:
What? No.

Derek:
Mark.

Mark:
You've been moving in on him all week. You weren't even interested in him until you saw how much he meant to me. I don't take the time to teach anyone if I can help it.

Derek:
Mark.

Mark:
But I'm takin' the time with Avery because he's a quick learner and he can do a c-plasty better than I could at his level.

Jackson:
I can? [Mark turns to walk away]

Derek:
Hey, hey. Don't do that. Don't just yell at me then walk away.

Mark:
I'm not. It's just that Sofia likes it if I'm moving.

Owen:
You guys talk. I'll take the baby.

Mark:
Okay, careful. We had a scare this week. [hands Sofia to Owen] Thank you. Now, Avery go get in the car. Friends don't steal from each other.

Derek:
It's not stealing if he asks to scrub in on my surgeries.

Mark:
Oh, don't be a jackass.

Jackson:

Mark:
[to Jackson] You usin' my boy here? To get more surgery? Nobody uses my boy. [Derek smiles, Jackson looks confused]
