Grey's Anatomy, Season 2

Meredith:
I never should have told you about George.

Derek:
No, it's fine. I'm glad I know about him. And the vet. You really get around.

Meredith:
What did you just say to me?

Derek:
It's unforgivable.

Meredith:
I don't remember ever asking you to forgive me.

Derek:
So was the knitting a phase? Who's next? Alex? Cause I hear he likes to sleep around. You two have that in common.

[Derek goes to leave. Meredith grabs him and he turns around]

Meredith:
You don't get to call me a whore. When I met you, I thought I had found the person that I was going to spend the rest of my life with. I was done, so all the boys, and all the bars, and all the obvious daddy issues. Who cared, because I was done. You left me. You chose Addison. I'm all glued back together now. I make no apologies for how I chose to repair what you broke. You don't get to call me a whore.

Derek:
This thing with us is finished. It's over.

Meredith:
Finally.

Derek:
Yeah. It's done.

Meredith:
It is done.

[Derek walks off, leaving Meredith alone. She begins to break down as she leaves]
