Terminator: The Sarah Connor Chronicles, Season 2

Sarah Connor:
I had planned on waiting for you with Derek's sniper rifle. Pulled the trigger, solve about 50% of my problems. One shot. Do you know how bad I would've felt?

Cameron:
Very bad?

Sarah Connor:
Not bad at all. But I know someone who would have felt bad. Someone who would have never forgiven me if I'd have done that. I don't know what to do with you. You know what the stakes are. You know why we're here. You know what this means. And yet here I stand, burning what's left of an endoskeleton I thought we'd burned months ago.

Cameron:
I needed spare parts.

Sarah Connor:
I don't care what you need, because this is not about you.

Cameron:
No, it's not about me. It's about John. You're concerned for his safety.

Sarah Connor:
You bet I am.

Cameron:
From Skynet. From me.

Sarah Connor:
Maybe. Maybe especially you.

Cameron:
We're all a threat. We're all a threat to John. He worries about us. It makes him vulnerable. He cares.

Sarah Connor:
I am not John's problem.

Cameron:
John is John's problem. Humans are the problem. There's only one way for him to be safe. That's to be alone.

Sarah Connor:
What kind of life is that?

Cameron:
John's life. Someday.
