Instead of the typical opening narration by Meredith, the voiceovers are provided by Denny.

Denny: (opening voiceover) I believe in heaven. I also believe in hell. I've never seen either but I believe they exist. They have to exist. Because without a heaven, without a hell, we're all just headed for limbo.

Bailey: Page Shepherd!
Meredith: The patient doesn't want that.
Bailey: Oh really, he tell you that?
William: Yes, don't page him. He's terribly unpleasant.

Bailey: Dr. Shepherd?
Derek: Dr. Bailey.
Bailey: I need you to stop. I need you to put down the scalpel. This man is trying to kill himself and, God forgive me, I need you to let him.

Mark: Little Grey.
Lexie: It's not Little Grey. It's Lexie. And I'm sorry that I broke ... that I hurt you. And I'm sorry that you're humiliated. But I'm not going anywhere. I've got a friend who is guarding the door. A good friend. And since no-one is going to be coming in, I'm now going to climb into bed with you and stroke your hair. Because that's what I like to have done for me, when I'm hurt.

Owen: I planned the whole evening, last night. A real date. It was a clear night, one of the five Seattle gets all year. I was going to take you to the West Point Lighthouse and we were going to watch the Northern Lights together. I'd like another chance. I want you to give me another chance.
Cristina: You've got some problems. You've got some big problems.
Owen: Yeah. Yeah, I do. Will, you go out with me anyway?
Cristina: Yes.

Owen: I want to apologize for last night. It was not my intention to arrive in that state.
Cristina: You don't have to say anything.
Owen: As a rule, if I'm showering with a woman, I do it without my clothes. And if I get in her bed naked, I don't pass out. And if I --
Cristina: It's okay.
Owen: It's not.
Cristina: It's not, but you don't have to talk about it.

Lexie: Oh my God! Are you okay?
Mark: No!
Lexie: It's bent in the middle. I think you broke it.
Mark: Get Torres! Go!

Bailey: Karev, go and get the machine.
Alex: What if it's already hooked up to somebody?
Arizona: If that somebody has more than sixteen hours to live, then we'll unhook him.

Meredith: (to Derek) I know you don't understamd me. I don't understand me. I wanted to show him compassion. That's why I went. That's the reason. And it was horrible.

Denny: (closing voiceover) Heaven. Hell. Limbo. No one even knows where we're going. Or what's waiting for us when we get there. But the one thing we can say, with absolute certainty, is that there are moments that take us to another place. Moments of Heaven on Earth. And maybe for now, that's all we need to know.
