Time To Investigate YourselfvTeddy: You don't know who you are anymore.
Leonard Shelby: Of course I do. I'm Leonard Shelby. I'm from San Francisco.
Teddy: No, that's who you were. Maybe it's time you started investigating yourself.
Let Me Be MyselfvLeonard Shelby: I'm not a killer. I'm just someone who wanted to make things right. Can't I just let myself forget what you've told me? Can't I just let myself forget what you've made me do. You think I just want another puzzle to solve? Another John G. to look for? You're John G. So you can be my John G... Will I lie to myself to be happy? In your case Teddy... yes I will.
The World Doesn't Just DisappearvNatalie: 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 vengeance. Doesn't make a difference whether I know about it. Just because 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.
I Am Not DifferentvLeonard Shelby: I have to believe in a world outside my own mind. I have to believe that my actions still have meaning, even if I can't remember them. I have to believe that when my eyes are closed, the world's still there. Do I believe the world's still there? Is it still out there?... Yeah. We all need mirrors to remind ourselves who we are. I'm no different.
The Present is TriviaLeonard Shelby: You know, I can remember so much. The feel of the world... her.
Leonard Shelby: She's gone. And the present is trivia, which I scribble down as f**king notes.
He Took Away My MemoryTeddy: You really want to get this guy, don't you?
Leonard Shelby: He killed my wife. He took away my f**king memory. He destroyed my ability to live.
A Useful ExperienceLeonard Shelby: I meet Sammy through work. Insurance. I was an investigator. I'd investigate the claims to see which ones were phony. I had to see through people's bulls**t. It was useful experience, 'cause now it's my life.
The Joy of Reading the BookLeonard Shelby: I always thought the joy of reading a book is not knowing what happens next.
Memory is Just a MemoryLeonard Shelby: Memory can change the shape of a room; it can change the color of a car. And memories can be distorted. They're just an interpretation, they're not a record, and they're irrelevant if you have the facts.
Making My Life PossibleLeonard Shelby: Sammy Jankis wrote himself endless notes. But he'd get mixed up. I've got a more graceful solution to the memory problem. I'm disciplined and organized. I use habit and routine to make my life possible. Sammy had no drive. No reason to make it work.
It Must Be Hard To Live Like ThatNatalie: 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.
I Know Some ThingsLeonard 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.
I Want My Life BackLeonard Shelby: I don't want your f**king money.
Jimmy Grantz: Then what? What do you want?
Leonard Shelby: I want my f**king life back!
Just A BluffLeonard Shelby: When I looked into his eyes I thought I saw recognition. Now I know. You fake it. If you think you're supposed to recognize somebody you, you just pretend. You bluff it to get a pat on the head from the doctors. You bluff it to seem less like a freak.
See Her With Your Eyes CloseNatalie: 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.
