Meredith (opening voiceover): At any given moment the brain has 14 billion neurons firing at a speed of 450 miles per hour. We don't have control over most of them: when we get a chill, goose bumps, when we get excited, adrenaline. The body naturally follows its impulses, which I think is part of what makes it so hard for us to control ours. Of course, sometimes we have impulses we would rather not control, that we later wish we had.
Addison: I need the day off.
Richard: A day off? For what?
Addison: For drinking. I am feeling the need to do some drinking. Actually, I’m feeling the need to do some crying, but my tear ducts seem to be too proud, so I am going to do some drinking instead.
Richard: What, no laboring moms today?
Addison: No … because I think God knows that I need to do some drinking today.
Richard: Do you want to talk about it Addy, or do you want to be glib a little bit longer?
Addison: Why are you living in your office?
Richard: Marriage is … hard.
Addison: Well, thank goodness. Mine seems to be just about over.
Cristina: His mother rivals my mother and that's saying something. Both of them, dark and evil.
Meredith: I'm miss dirty stripper Cristina. She was fun -- a lot less angry.
Cristina: Next time she even looks at me sideways, I’m telling her what I think. She wants to call me a racist. Yeah, okay? I’ll call her a sexist. Change my career after I’m married. What is this, 1953? If she comes at me, I’m going there.
Meredith: I think you should. I think we should all just go there. You know, tell the truth, spit it out, go with your gut, follow your instincts.
Cristina: I miss philandering whore, Meredith. She was trashy and much less idyllic.
Callie: The panties?
Callie: Not mine. The jealousy?
Callie: Insanely hot.
Cristina: I told you to guard the door!
Nurse Tyler: I had a code blue.
Cristina: I had parents walk in.
Nurse Tyler: We saved the guy’s life.
Cristina: Whatever, I want my 20 bucks back.
Nurse Tyler: Sorry, I bought everyone coffee to celebrate saving the guy’s life.
Derek: It’s not an affair. I was gonna tell her, Addison, I was gonna tell her today.
Richard: Give her some space, give her some time.
Derek: No. That’s not it. No. I gotta tell her today. When something’s over, it’s just gotta be over. Meredith she’s ... she’s not an affair.
Finn: You bowing out?
Derek: No, you?
Finn: I don’t think so.
Bailey: O’Malley, Yang, prep your patients for surgery. Karev pit, Grey charts. All four of you do not make me regret setting you loose in this hospital. O’Malley, what do I mean by that?
George: You mean check with you before we cut any wires or steal any hearts.
Meredith: It's not Tyler's fault you're a dirty dirty stripper.
Meredith (closing voiceover): The body is a slave to its impulses. But the thing that makes us human is what we can control. After the storm, after the rush, after the heat of the moment has passed, we can cool off and clean up the messes we made. We can try to let go of what was. Then again...
