Hiro: All the books I read said the sword is here.
Ando: So what? We finally make it to New York and all you care about is a sword. What about your mission?
Hiro: I need my powers for the mission!
Ando: But the bomb is going off on November 8th. We only have three more weeks.
Hiro: I know, but ever since I lost Charlie my powers have gotten weaker and weaker. My sword will restore my powers.
Ando: It's not your sword.

Hiro: See? I'm like him. The sword will give me the control over my power I need. It's my sacred object. With it my powers will return and I can fulfill my destiny.
Ando: What exactly are you saying?
Hiro: I'm saying we take it.
Ando: We?

Nathan: Just before he passed out he said he, uh...he felt he was absorbing too many powers.
Simone: Peter wanted to see that painting.
Nathan: After I told you not to let him, you knew he was gonna follow that thing head first all the way to Texas. He's my brother, and I love him, but we both know he shouldn't have even been there.
Simone: It was important to him.
Nathan: You really believe all this crap? Future paintings? The end of the world?
Simone: I know he believes it. And I believe in him.

Matt: Listen to me, I have no idea how you're pulling this off, but I swear to God, I'm not going to stop until I figure it out. You understand me?
Bennet: Good luck with that.

Ando: There's security everywhere. Stealing isn't exactly part of Bushido code, you know.
Hiro: It's one antique. If I don't have my powers this whole museum will explode anyway. It's a good deal for them.

Claire: "Save the cheerleader, save the world." Have I been saved, or do I still need saving?
The Haitian: You are saved for the time being.

The Haitian: What you can do, what I can do — that is God. Respect it accordingly.

Hiro: The bomb, it comes from the street. Destroy everything, everything turn into dust. poof!
Nathan: Your English is a lot better.
Hiro: I met a waitress in Texas.
Nathan: Oh, yeah?
Hiro: She teach me many things.
Nathan: Good for you.
(Hiro bows his head)
Nathan: So, uh, look, I can't believe I'm about to say this, you -- you teleported here ... back from the future.
Hiro: Yes, my power let me come back here so I can stop it.
Nathan: Right. Because "you hero."
Hiro: You will help too.
Nathan: Me? What makes you so sure?
Hiro: You flying man. Whooshhhh!
Nathan: Will you keep it down?!
Hiro: (quieter) Whooshhhhh.
Nathan: What do you think it is that makes this bomb thing go off?
Hiro: Don't know. Probably bad guy?
Nathan: Bad guy?
Hiro: Yes. (with a heavy accent) Like villain.
Nathan: What's that?
Hiro: (with a heavy accent) Villain.
Nathan: Villain?
Hiro: (with a heavy accent) Villain.
Nathan: Villain.
Hiro: Vee.
Nathan: V.
Hiro: Vee-yun.

Zach: Hold on a second. I’m sure you told me this before, but, um, why are we videotaping this, whatever this is?
Claire: Actually, I didn’t tell you that before. The first time I did this I did it to show my parents, my real parents. I wanted them to see what I was. I thought they could help me understand. But I don’t think I’m ever gonna meet them. They may not even be alive any more.
Zach: So why do you wanna tape it now?
Claire: For me. So I never forget what I am, no matter what happens to me. Just don’t freak out, okay?

Matt: All right. Pick a number between one... and a million.

Niki: God, please help me.
Jessica: Who needs God when you've got me?

Mohinder: (closing voiceover) In the beginning there was discovery. A confusion of elements. The first snowfall of impossible change. Old lives undone, left behind. Strange faces, made familiar. New nightmares, to challenge sleep. New friends, to feel safe with. Only then comes control. The need to impose order unto chaos, through determination through study, through struggle. All in defiance of a thundering truth. They’re here, and the earth shudders underfoot.
