Grey's Anatomy Season 4 Episode 15 Quotes

Dr. Wyatt: We had our first honest conversation about your feelings, and now you want to leave. That timing doesn’t strike you as strange?
Meredith: No, and I’m still firing you.
Dr. Wyatt: No, you’re quitting.
Meredith: No, I’m not quitting. I don’t quit things.
Dr. Wyatt: No, actually you do. Your mother quit your father. Your father quit you. You quit your boyfriend and if I read your hospital chart correctly you quit your life momentarily on a couple of occasions. You quit. It’s what you know how to do.
Meredith: Now you’re really fired.

Callie: Give me two minutes I'll meet you in the third-floor on-call room.
Mark: [points to his pants, then his head] No. We're gonna sit, enjoy a nice meal. I've turned over a new leaf. From now on if you want this, you're gonna get this too.
Callie: Eww.
