Terminator: The Sarah Connor Chronicles, Season 2

John Connor:
We were using it for research. To find out what makes them --

Sarah Connor:
Don't! John, just don't. Don't make excuses her. Don't cover for her.

John Connor:
I knew about the parts.

Sarah Connor:
I'm not talking about parts. I'm talking about Riley.

John Connor:
Well, there's nothing to talk about, is there, because Riley's dead.

Sarah Connor:
How do you think that happened?

John Connor:
I don't know. I'm going to figure it out, though.

Sarah Connor:
You know, John. We both know.

John Connor:
No. Cameron didn't do it.

Sarah Connor:
How can you say that? How can you be so sure?

John Connor:
Because I'm sure, and I know her, and she told me.

Sarah Connor:
Yeah, she told you. Just like she told you she destroyed every part we ever captured. Just like she tells us what she does every night when we go to sleep. When she comes back in the morning she's covered in cuts and bruises. Just like she told you she loved you!

John Connor:
[Bangs his fist on the table] You don't know anything!
