Elijah Price: Do you know what the scariest thing is? To not know your place in this world, to not know why you're here.
Elijah Price: It has begun. Tell me something, David. When you woke up this morning... Was it still there? The sadness?
David Dunn: No.
Elijah Price: I think this is where we shake hands.
Elijah Price: [flashback occurs upon shaking] I worked in that building 25 years, I know all its secrets.
David Dunn: Secrets?
Elijah Price: Like, if there ever was a fire on floors 1, 2 or 3, everyone in that hotel would be burned alive.
[after flashbacks end]
Elijah Price: You know what the scariest thing is? To not know your place in this world. To not know why you're here... That's... That's just an awful feeling.
David Dunn: What have you done...?
Elijah Price: I almost gave up hope. There were so many times I questioned myself...
David Dunn: You killed all those people...
Elijah Price: But I found you. So many sacrifices, just to find you.
David Dunn: Jesus Christ...
Elijah Price: Now that we know who you are, I know who I am. I'm not a mistake! It all makes sense! In a comic, you know how you can tell who the arch-villain's going to be? He's the exact opposite of the hero. And most times they're friends, like you and me! I should've known way back when... You know why, David? Because of the kids. They called me Mr Glass.
Elijah Price: Why is it, do you think, that of all the professions in the world you chose protection?
David Dunn: You are a very strange man.
Elijah Price: You could have been a tax accountant. You could have owned your own gym. You could have opened a chain of restaurants. You could've done of ten thousand things, but in the end, you chose to protect people. *You* made that decision, and I find that very, very interesting.
Elijah Price: Do you see any Teletubbies in here? Do you see a slender plastic tag clipped to my shirt with my name printed on it? Do you see a little Asian child with a blank expression on his face sitting outside on a mechanical helicopter that shakes when you put quarters in it? No? Well, that's what you see at a toy store. And you must think you're in a toy store, because you're here shopping for an infant named Jeb.
Elijah Price: This is an art gallery, my friend, and this is a piece of art.
Joseph Dunn: Do you think you could beat up Bruce Lee?
David Dunn: No.
Joseph Dunn: I mean, if you knew karate?
David Dunn: Nope.
Joseph Dunn: What if he wasn't allowed to kick, and you were *really* mad at him?
David Dunn: No, Joseph.
David Dunn: You should never do anything like this. You know that, right?
Joseph Dunn: Yeah.
David Dunn: What should you do if something bad happens?
Joseph Dunn: Get Mom.
Comic Book Clerk: You'd better not be back there jacking off to the Japanese comics, I swear to God...
Joseph Dunn: I thought maybe because you're my dad... I thought I might be like you... I'm not like you...
David Dunn: You are like me. We can both get hurt. I'm just an ordinary man.
Joseph Dunn: No, you're not... Why do you keep saying that?
Elijah Price: You made that decision, and I find that very, very interesting. Now all I need is your credit card number...
ER Doctor: And, to answer your question, there are two reasons why I'm looking at you like this. One because it seems in a few minutes you will officially be the only survivor of this train wreck, and two, because you didn't break one bone, you don't have a scratch on you.
David Dunn: Friends listen to each other! And they don't shoot each other, do they Audrey?
Audrey Dunn: N-... No shooting friends, Joseph...
Dr. Mathison: It appears that your baby has sustained some fractures while inside your uterus... his arms and his legs are broken.
[Elijah's mother bursts into tears]
Orange Suit Man: I like your house. Can I come in?
Hostage Father: No.
Orange Suit Man: Are you sure?
David Dunn: I wanted to ask you a question. It's gonna sound a little strange, just think about it for a second, okay?
Audrey Dunn: Okay.
David Dunn: When's the last time I was sick? Do you remember?
Audrey Dunn: Um, I don't know. It's been a while.
David Dunn: I haven't been sick this year, I know that.
Audrey Dunn: Okay.
David Dunn: Do you remember me getting sick?
Audrey Dunn: Um... not a specific day. What - what's this about?
David Dunn: Audrey, do you remember me ever getting sick? In the three years we lived in this house? In the old apartment? Before Joseph was born? Before we ever got married?
Audrey Dunn: I - I can't remember.
David Dunn: Don't you think that's kind of weird, not remembering one cold or a fever or a sore throat? What do you think it means?
Audrey Dunn: Um... I think it means probably too tired to remember.
Elijah Price: One of us has made a gross error, and wasted the other person's valuable time.
Elijah Price: It's hard for many people to believe that there are extraordinary things inside themselves, as well as others. I hope you can keep an open mind.
Elijah Price: It's alright to be afraid, David, because this part won't be like a comic book. Real life doesn't fit into little boxes that were drawn for it.
David Dunn: You killed all those people.
Elijah Price: But I found you. So many sacrifices just to find you.
Elijah Price: [from deleted scene] Can I tell you a secret? I'm going to be very, very sad if this doesn't work out the way I think.
David Dunn: [talking to Elijah on phone] I've never been sick, I've never been injured... what do I do now?
Elijah Price: Go to a place where people are... you won't have to wait very long.
Elijah Price: I have something called Osteogenesis Imperfecta. It's a genetic disorder. I don't make a particular protein very well and it makes my bones very low in density... very easy to break.
Elijah Price: Your bones don't break, mine do. That's clear. Your cells react to bacteria and viruses differently than mine. You don't get sick, I do. That's also clear. But for some reason, you and I react the exact same way to water. We swallow it too fast, we choke. We get some in our lungs, we drown. However unreal it may seem, we are connected, you and I. We're on the same curve, just on opposite ends.
