Hiro Nakamura: Are you a time traveler too? Are you following me? What are you doing here, Butterfly Man?
Samuel Sullivan: The question is, what are you doing here?
Hiro Nakamura: I'm here to save Charlie.
Samuel Sullivan: And why would you be doing something like that?
Hiro Nakamura: You told me I could right the wrongs of my life by stepping on the right butterflies. This is the biggest. It's Mothra.
Samuel Sullivan: I'm here, Hiro, to make sure you understand the magnitude of your endeavor. To protect you. This isn't a simple spilled slushy. Look. You were on a specific path. Everyone was. Sylar and Peter and Claire. I'm making a tremendous sacrifice to make sure you succeed, Hiro. This place is a mine field. One mistake here, and it's kablooey, history. Awful lot of trouble for one girl. Pretty as little Susie Flapjacks is, is she absolutely worth it?
Hiro Nakamura: Yes.
Samuel Sullivan: My family is shrinking and our graveyard's getting bigger. We need Hiro Nakamura.
Lydia: You said he was on a path.
Samuel Sullivan: And it's a damn long walk. We need him now. It's not gonna be easy.
Lydia: Oh, come on, you can convince an apple that it's an orange.
Samuel Sullivan: Desperate times, desperate measures. And all that.
Hiro Nakamura: I'm the good guy.
Pistol Petey: Good guys wear white hats.
Samuel Sullivan: You sure you got all your Is crossed and your Ts dotted?
Hiro Nakamura: You're not Butterfly Man. You're Evil Butterfly Man.
Hiro Nakamura: I'm Future-Hiro.
Ando Masahashi: Where's your sword?
Hiro Nakamura: I will tell you how you die. You die alone. I'm sorry.
Sylar: What the hell is that supposed to mean?
Hiro Nakamura: It means that you will collect a lot of powers. You'll kill many people. You'll become strong, the strongest of them all. But in the end, it won't make any difference. We all gather to stop you. You're alone. No one will mourn your death. No one will shed a tear. No one. I wish I can change fate. But you must go on your path.
[Hiro has saved Charlie's life]
Charlie Andrews: Hiro, 300,000 people die every single day - young, old, there are accidents, murders. Why am I any different? Why do I get to live?
Hiro Nakamura: Because I love you.
Charlie Andrews: Then that's just selfish.
Hiro Nakamura: [quoting a haiku] "The thief left it behind; the moon at my window." Even if everything else is lost, we will always have our love. No thief, no illness can ever take it away.
