Natalie: Tell me about her again.
Leonard Shelby: Why?
Natalie: Because you like to remember her.
Leonard Shelby: She was beautiful. To me, she was perfect.
Natalie: No, don't just recite the words. Close your eyes... and remember her.
Leonard Shelby: You can just feel the details. The bits and pieces you never bothered to put into words. And you can feel these extreme moments... even if you don't want to. You put these together, and you get the feel of a person. Enough to know how much you miss them... and how much you hate the person who took them away.
Natalie: Get rid of Dodd for me. Kill him. I'll pay you.
Leonard Shelby: Are you crazy? I'm not gonna kill someone for money.
Natalie: What then? Love? What would you kill for? You'd kill for your wife, wouldn't you?
Leonard Shelby: That's different!
Natalie: Not to me, I wasn't fucking married to her!
You know what one of the reasons for short term memory loss is? Venereal disease. Maybe your cunt of fucking a wife sucked one too many diseased cocks and turned you into a fucking retard.
Leonard Shelby: There are things you know for sure.
Natalie: Such as?
Leonard Shelby: I know what that's going to sound like when I knock on it. I know that's what going to feel like when I pick it up. See? Certainties. It's the kind of memory that you take for granted.
Is that what your little note says? It must be hard living your life off a couple of scraps of paper. You mix your laundry list with your grocery list you'll end up eating your underwear for breakfast.
You sad, sad freak. I can say whatever the fuck I want, and you won't remember. We'll still be best friends. Or maybe even lovers.
You know what? I think I'm gonna use you. I'm telling you now because I'll enjoy it so much more if I know that you could stop me if you weren't such a fucking freak!
Natalie: But even if you get revenge you're not gonna remember it. You're not even going to know that it happened.
Leonard Shelby: My wife deserves vengance. Doesn't make a difference whether I know about it. Just becuase there are things I don't remember doesn't make my actions meaningless. The world doesn't just disappear when you close your eyes, does it? Anyway, maybe I'll take a photograph to remind myself, get another freaky tattoo.
Natalie: What's the last thing that you do remember?
Leonard Shelby: My wife...
Natalie: That's sweet.
Leonard Shelby: ...dying.
