Richard

[narrating] It isn't just surgeons. I don't know anyone who isn't haunted by something or someone. And whether we try to slice the pain away with a scalpel or shove it in the back of a closet ... our efforts usually fail. So the only way we can clear out the cobwebs is to turn a new page or put an old story to rest.... finally, finally to rest.

Meredith

Happy freakin' Halloween.

Alex

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."

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.
