Hiro: [in broken English] You will help too!
Nathan: Me? What makes you so sure?
Hiro: You're flying man! Woooooosh!
Nathan: Shh! Will you keep it down?
Hiro: [quietly] Whoooosh.

Hiro: [to Parkman] You are like me. Special. Why do you want to hurt other special people?

Hiro: Find something you like to do. Then it doesnt feel like work.
Hiro: Life is a gift, precious and short, not [to be] wasted by jumping off a roof.
Hiro: Don't keep secrets. Not from the ones you love. Especially family members.

Hiro: Future Hiro killed so much, he forgot it should be hard.

Hiro: Have you seen a scary white man?
[in Japanese]

Hiro: He's so sad.
Ando: He's distracted. Go on, do it!
Hiro: I can't kill a man who is asking for forgiveness. It's not in the Bushido code. Everyone deserves a second chance.
[outside his mother's room, banging on the door.]

Hiro: I am very special, I offer myself in trade! Release unspecial Ando!

Hiro: I have so many stories to share with you, Kimiko. I just hope I have time to tell you them all.

Hiro: I look upset.
Ando: Go. Talk to yourself.
Hiro: No way... I scare me. You do it.

Hiro: I refuse to eulogize my father. To eulogize him is to admit he is gone. My father is not dead. Kaito Nakamura taught me right from wrong. What it means to be a hero... so long as the lessons live on through me, he will never die. My father taught me to understand that certain things are in God's hands, but for everything else, God has given us the gift of choice. My father gave me the tools to fight the battles ahead. Every hand I extend in kindness is his hand. And every blow that I strike for justice is his fist. So long as the lessons he taught stay with me, and so long as he lives on in my heart, then my father is never truly dead.

Hiro: I suppose this is... goodbye.
Kaito: I've never time traveled before. I'm proud of you son.
Hiro: Goodbye Father. Please give my love to Mother.

Hiro: I understand, Father. To save what is most important... I must be strong enough... to cut out my heart.

Hiro: It was the kiss that fractured time.
(Alejandro is beating up Sylar next to the car.)

Hiro: Kensei! I've been searching for hours. Come my friend, we must go back and destroy White Beard's guns.
Kensei: If you want to stop him do it yourself.
Hiro: Something wrong?
Kensei: I saw you Hiro. After I saved the swordsmith I came looking for you, afraid something happened to Yaeko, 'cause I love her. And you, friend, betrayed me.
Hiro: No-
Kensei: Yes, you kissed her.
Hiro: It happened by accident.
Kensei: You accidentally kissed her?
Hiro: I accidentally fell in love with her. And she with me. I'm so sorry.
Kensei: So you've been lying to me all along. First you show me that I can be harmed by no weapon and then you hurt me deeper than any blade possibly could.
Hiro: She's your princess, Kensei. I know that. And I swear I will not give into love. That kiss will be our last.

Hiro: Matt Parkman, meet Matt Parkman.
