Meredith: (voiceover) In life only one thing is certain, apart from death and taxes: No matter how hard you try, no matter how good your intentions, you are going to make mistake. You are going to hurt people. You are going to get hurt. And if you ever want to recover, there's really only one thing you can say.
Meredith: (to Derek) Not-couples have no reason to go away together.
George: Callie ... you haven't said anything and ... just say something ... please, anything.
Callie: I forgive you.
Callie: You made a mistake, but we took vows, "'til death do we part," so ... I forgive you.
Izzie: Callie! Hey. Hi.
Callie: We have to talk.
Izzie: Okay. Um, about?
Callie: George told me.
Izzie: He told you.
Callie: Everything. Cafeteria. Noon. You and me. Be there.
Izzie: No, she's saving all her rage and bloodshed for me. And she's gonna kill me in the cafeteria at lunch.
George: No, she wouldn't.
Izzie: She breaks bones for a living George! She's crazy!
George: No, she's not crazy.
Izzie: Well, she is if she thinks I'm not gonna put up a fight.
Bailey: People are stupid and just want to be loved. That's the only reason anyone does anything.
Cristina: (to Izzie) You were very ghettofabulous.
Lexie: I just wanted to say thank you for saving my ass in surgery today.
Cristina: That's my job, 3.
