- Denny Duquette: Heaven, Hell, Limbo No-one really knows where we're going or what's waiting for us when we get there, but the one thing we can say for sure with absolute certainty is there are moments that take us to another place, moments of Heaven on earth, and maybe for now, thats all we need to know.
- Denny Duquette: 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.
- Dr. Isobel 'Izzie' Stevens: Heaven or hell?
- Denny Duquette: Yes.
- Dr. Isobel 'Izzie' Stevens: You're here for me.
- Denny Duquette: Yes.
- Dr. Isobel 'Izzie' Stevens: No.
- Dr. Isobel 'Izzie' Stevens: You're not here for me. You're here FOR me. You're here for me.
- Denny Duquette: I loved you so much. I loved you so much that when I got to come back for you, I thought... you were my heaven. But maybe... maybe I'm your hell.
- Dr. Isobel 'Izzie' Stevens: I'm sick. I'm sick, aren't I? And instead of telling me... instead of telling me to save my life - you son of a bitch! You selfish son of a bitch. I hate you! I hate you!
- Denny Duquette: I didn't know that there was a chance. Miracles happen. Medical miracles happen every day. You said it! You said that!
- Dr. Isobel 'Izzie' Stevens: Leave! Leave.
- Denny Duquette: I can go now... because you know. But it's your choice. You get to choose. But, Iz, If I go... I don't know... I don't know if I can come back. If I go...
- Dr. Isobel 'Izzie' Stevens: In the choice between heaven and hell, I choose heaven. I choose life. Go. Get out of here! Go out get of here! Go.
- Denny Duquette: I really hope this is heaven.
- Dr. Isobel 'Izzie' Stevens: Go. What are you waiting for?
- Denny Duquette: This. *Denny kiss Izzie*
- Dr. Isobel 'Izzie' Stevens: I can feel you. I can smell you. If you're dead, how come I can smell your skin? So I'm thinking, maybe you're not dead. Maybe that was the part of me that was crazy, that part that thought you died. Maybe this is the not crazy part. You are still alive, right? That's it.
- Denny Duquette: I'm sorry. No.
- Dr. Isobel 'Izzie' Stevens: Are you a ghost... or a dream or...
- Denny Duquette: You're a doctor, Izzie, a scientist. Think like a scientist.
- Dr. Isobel 'Izzie' Stevens: I am! I am. Scientists believe what they can see, what they can feel... Facts. Hard facts. *she gives a slap in his face* I slapped you. That is a fact. I felt... your face my hand. Fact. I can feel your breath against my skin. Fact.
- Denny Duquette: Izzie. Izzie, Izzie.
- Dr. Isobel 'Izzie' Stevens: *she starts to cry* What's happening?
- Denny Duquette: You tell me.
- Dr. Isobel 'Izzie' Stevens: I'm scared.
