Grey's Anatomy, Season 4

Mark:
I tried to change, turn over a new leaf. But the leaf isn't turning.

Webber:
You weren't ready to change. And that's okay. Adele wanted me to change, to retire. Well, I'm still the chief and this weekend, I'm moving back home.

Derek:
Does Adele know that?

Webber:
Oh, she'll be fine. She was wrong. I was right. And now we're––

Mark:
Doing it like bunnies. [mutters to himself] I can't change. I can't change. I can't change.

Webber:
Be who you are. I am who I am. A man.

Mark:
A man. [Derek shakes his head in amusement] I have a way about me. A man who is who he is. I have a right to be that man.

Derek:
[shakes his head] Tsk. I'm not gonna say anything. No judgement. [looks at Mark] The man you are: you slept with my wife. [looks at Richard] And you: you've been on my land for six months. But I've got no judgement.
