Adam: Objection your honor, he's reciting the opening to Quantum Leap.

"Nathan": Every time there's a secret buried someplace, I find you with a shovel behind your back.
Angela: You should write Mother's Day cards.

Ando: Who are you calling?
Hiro: The comic book author. To warn him about the future. He keeps hanging up on me.
Ando: That's because you're crazy. I'd hang up on you too, if I could.

Ando: What happened to Hiro? Who was that?
Future Hiro: Homeland Security.
Ando: The government?
Future Hiro: They're taking him to a special holding facility in midtown.
Ando: How do you know that?
Future Hiro: Because that's where they take all the terrorists.
Ando: Why would anyone think Hiro's a-- You? A terrorist?
Future Hiro: After Sylar exploded, the world became a very dark place.

Ando: Every hero is on a journey to find his place in the world. But it's a journey. You don't start at the end, otherwise they can't make a movie about it later.

Ando: What happened to me? Where am I? Am I rich? Married?
Future Hiro: I can't tell you that.
Ando: Why not?
Future Hiro: Because ... [translated from Japanese] The whole time/space continuum ... might implode because you were impatient.

Ando: I'm confused. You said you called me when you went in the future.
Hiro: Yeah. So?
Ando: So, shouldn't I be at home waiting for your call?
Hiro: We're changing the future. By taking action, we've changed something.
Ando: What if we make it worse? And if there's going to be a nuclear explosion, shouldn't we be flying away from the bomb?
Hiro: A hero doesn't run away from his destiny. My only concern is whether I need to hide my true identity. Perhaps a costume?
Ando: You even mention tights and a cape, I'm going home.

Adam: You know, it's been a month. You still haven't told me your name.
Peter: Please, I just wanna be left alone.
Adam: You came to the right place. I have to warn you though, it does get a bit old. Let me guess, you were living a perfectly ordinary life until one day you discovered you could do incredible things. I bet it was wonderful at first. You thought perhaps you could save the world. And then you realized, tragically, that you were dangerous. I'll let you talk to me after a decade. Oh, actually, talk to me after three.
Peter: If they wanna leave me in here forever that's fine by me.
Adam: You've been through something awful haven't you? I'm sorry.
Peter: I'm Peter.
Adam: Hello, Peter. It's nice to meet you. I'm Adam.

Ando: [to Hiro] Future you doesn't count as you.

Ando: You came from the future and told them to save the cheerleader. Oh, and you had a sword.
Hiro: I had a sword?

Adam: (marks a picture of Victoria with the double helix in his blood.) If anyone survives, I'll tell them I couldn't have done it without you.

Adam: Wars, famine, disease. 400 years later, nothing has changed. When God wasn't happy with what he created, he made it rain for 40 days and 40 nights. He just washed it all away. He had the right idea, because when this virus is released, those of us who are left will be granted a second chance. And I'll be their hero.

Ando: Is everything alright?
Future Peter: No, let's go fix it.

Adam: (Yelling) Let me out! Carp, Let me out! Carp! Let me out!

Ando: (In Japanese) Hiro? Where have you been?
Hiro: (In Japanese) I went to face my father's killer.
Ando: (In Japanese) Well, did you find him? (Hiro nods) Did you kill him?
Hiro: (In Japanese) He can never hurt anyone ever again.
