Meredith: How am I related to that man?
Cristina: What do you mean?
Meredith: Look at him. He's a mess.
Izzie: Yeah.
Meredith: I mean he's a disaster. He's a stammering, mumbling, clumsy disaster with whom I have absolutely nothing in common. Not one thing.
Izzie: I hate to break this to you --
Meredith: What?
Cristina: Well, you know, you do your own share of stammering yourself.
Izzie: Yeah, that nervous talking thing you do? It's actually a lot like him.
Cristina: Mmm hmm.
Meredith: No, it's not.
Cristina: Plus, that messy thing.
Izzie: Oh, totally.
Meredith: (to Cristina) You're the messy one.
Cristina: No, my apartment's messy, my locker's messy, but I am not messy. Sometimes, you know, you have like food and stuff in your hair.
Izzie: Yeah, food. Band-aids on your face. I can kind of see the indentation from the nose strip you were wearing last night.
Meredith: (to Cristina) You are in a relationship with no words. (to Izzie) And you are a millionaire in twenty dollar shoes. Whatever.

Cristina: There's a club. A dead dads club. And you can't be in it until you're in it. Hey, you can try to understand, you can sympathize, but until you feel that loss. My dad died when I was nine. George, I'm really sorry you had to join the club.
George: I, I don't know how to exist in a world where my dad doesn't.
Cristina: Yeah, that never really changes.

Addison: About eight months ago, I peed on a stick, and I wasn't even gonna tell him but then I did tell him. And he went out and bought this insane Yankee's onesie and a calendar and marked the due date, which I should mention is today.
Callie: You didn't want a baby?
Addison: I wanted Derek. I wanted to have a baby with Derek. I never thought I'd end up alone.
Callie: You have not ended up anywhere.
Addison: Yeah, I know, it's just that, uh, sometimes it feels that way, you know? This is one of those weeks it feels that way.
