Heroes, Season 3 (Volume 3: Villains)

[Meredith is using her power to use up all the oxygen in the metal box that she and Claire are in]

Claire:
What's this supposed to prove? I've walked through fire before and I haven't gotten burned.

Meredith:
You've never been burned?

Claire:
I'm indestructible. I can't feel pain.

Meredith:
You ever suffocate? 'Cause I would imagine the air is getting pretty thin in here.

Claire:
Why are you doing this?

Meredith:
Why do you wanna stop bad guys?

Claire:
I told you. To help people.

Meredith:
That's what you keep saying. But I don't believe you. Do you know what waterboarding is, Claire?

Claire:
No.

Meredith:
It's a method of torture. You're not drowning but your body tells your mind that you are. You think you're gonna die. Trapped, you panic. Trapped. Does that remind you of anything?

Claire:
Stop it! Turn it off!

Meredith:
Is this how it was with Sylar, huh? You're indestructible but you couldn't get away, right? Well, that must have made you feel trapped. Helpless.

Claire:
Please stop! I can't--

Meredith:
Why do you wanna stop bad guys?

Claire:
To help people!

Meredith:
I don't believe you. You tell me why!

Claire:
To hurt him, okay! To hurt him for what he did! Like he hurt me!
