(Peter is holding the piece of glass Claire pulled out of his head)
Peter: What do you do with something that killed you?
Nathan: You could put it underneath your pillow. (pauses) I don't know what I would've done.
Peter: Don't think about it. I didn't die.
Nathan: Yeah, but if you had... I don't know who I am without you.
Peter: Of course you do. You're Nathan Petrelli. Top of his class, valedictorian, most likely to... you're that guy with me or without me.
Nathan: Who says I'm not all that because of you? Most of what we are is what people expect us to be, and if you take them away, nothing means anything.
Peter: It's a good thing I can't die, then.
Peter: Oh, I got that from Claire. She can regenerate.
Nathan: No matter what happens?
Peter: I think so.
Nathan: What about the painting? If you explode, I mean if that happens, you could survive it?
Peter: Doesn't really matter, does it? I mean, if I go nuclear, if I blow up New York, you know how many people are gonna die?
Peter: Talk to her, Nathan. She wants to know her father.
Nathan: I can't deal with that right now.
Peter: She's not just some girl, she's your daughter. You know that Mom wants to send her to Paris? You can't let her go. Don't you get it? Claire's the girl I saved in Texas, save the cheerleader-
Nathan: Save the world, I get it.
Peter: And she turns out to be your daughter. YOUR daughter. Look around. Everything I said is happening is happening now. And maybe if Claire's here, I don't blow up. Maybe she's here to save us. Talk to her, Nathan. We need her.
(Angela Petrelli walks in)
Peter: About what just happened, Nathan and I need to talk to you.
Angela: It's okay, I know. I knew before either of you did.
