Mark: Oh man, you would not believe what just happened to me.
Derek: There is, uh, a kid looking for you.
Mark: What?
Boy: Daddy?
Mark: WHAT?
Derek: Nicely done.
Boy: Thanks.
Mark: I'll be getting you back for that.
Derek: Looking forward to it.

Derek: What did you do?
Mark: I spread the word you were lookin'
Derek: You spread the word I was looking?
Mark: Lookin' ... it sounds much dirtier without the "g."

I heard. About your marriage. And if there’s anything you need me to do, to cheer you up, I’m around. Day or night. Night, in particular.

Mark

You gotta love Halloween. All the crazies come out to play.

Derek: It’s a little...
Meredith: It’s not that strange. I mean, I’m trying to figure out how to put her to rest. I can’t shove her in the back of my closet anymore. I have to deal with her. And this is me trying... to evolve. I’m trying here. So, cubby or car?
Derek: You’re asking me if I think you should put your mom’s ashes in your cubby or your car. You don’t think that’s very very strange?
Boy: Are those really your mom’s ashes?
Derek: It’s strange, right? It’s strange.

Derek: What is that?
Meredith: It’s charts.
Derek: Meredith…
Meredith: It’s my mom. I had her in the cubby and she was freaking people out. I was just gonna go put her in the car. Do you think that’s disrespectful? To leave her in the car?

[narrating] There’s a reason surgeons learn to wield scalpels. We like to pretend we’re hard, cold scientists. We like to pretend we're fearless. But the truth is we become surgeons because somewhere deep down we think we can cut away that which haunts us. Weakness, frailty, death.

Callie: You should direct your questions to Dr. Bailey, Stevens.
Cristina: Oh, we’re directing our questions to Dr. Bailey?
Callie: Oh, not you, just Stevens.
Miranda: Why is Stevens directing her questions to Dr. Bailey?
Callie: Because she’s been sleeping with my husband. Alrighty then, have a good day.
Cristina: [to Mer] This is more disturbing than your bag full of Mommy.

Cristina: What are we looking at?
Izzie: Meredith put her Mom in a baggie and brought her to work.
Meredith: I had to get her out of my closet, she was haunting me.
Alex: Now she’s haunting us all.

Richard: Dr. Yang, did you hear? Dr. Hahn has agreed to become our new head of cardio-thorasic surgery.
Cristina: You can't have my apartment.

Mark: Good morning.
Olivia: Don’t. Don’t do that. Don’t smile at me.
Other Nurse: Don’t smile at her. Don’t smile at me either.
Olivia: We’re on to you.
Other Nurse: We’ve compared notes.
Mark: Compared notes? Really?
Olivia: Compared notes. Compared pick-up lines. Compared techniques.
Mark: Techniques...
Olivia and Other Nurse: Identical.
Mark: Identical?
Olivia: We formed a club. Nurses United Against Mark Sloan.
Mark: Are there any club activities?

[narrating] In the practice of medicine, change is inevitable. New surgical techniques are created, procedures are updated, levels of expertise increase. Innovation is everything, nothing remains the same for long. We either adapt to change, or ... we get left behind.
