Derek: Remind me again, why are the boys out here and the girls in there?
John: Because one of the boys is still wanted for murder, and one of the girls is harder than nuclear nails.
Derek: And the other one's a cyborg.

Sarah: Can you get through the door?
Cameron: Yes, but the wall would be much faster.

Ellison: If Sarah is alive and I believe she is, we are working in a realm where much perhaps anything is possible, robots, soldiers from the future, Skynet.
Charley Dixon: If Sarah were alive, I'm sure she's like to hear you say that.

Charley: (talking about Agent Ellison) If he believes you, he can protect you.
Sarah: Do you remember what you saw here? What we destroyed, who destroyed it? The FBI can't protect us, you can't protect us. If one of them follows you here, not the FBI, one of them, you'll have killed us.

Cameron: Do I have a birthday?
John: I don't know. Were you born?
Cameron: I was built.
John: Well maybe you have then, like a built day.

Charley: I'm gonna tell you, what I told the other guy. I don't know anything.
Ellison: The other guy?
Charley: Yeah, the other agent you guys sent here, Kester.

Cromartie in the disguise of Agent Kester visited Charley in episode 1x05, Queen's Gambit.

Fake Sarkissian: (to Carlos) You know what I think? I think she (Sarah) went to him (Enrique) looking for identification, and I think he sent her to you.

This interchange is regarding Sarah's attempts to acquire false identification in episode 1x02, Gnothi Seauton.
