Cameron's attempt to talk to the bird at the beginning of the episode is another sign of her continuing malfunctions.

Parts from various Terminator models are interchangeable.

Cameron is not a Terminator model designed for fighting.

Sarah: I was wondering when we'd see you again.
Riley: They make you rest a couple days.
Sarah: Does it help.
Riley: Not really.

Riley: It shouldn't have happened here, or not at all. (talking about her suicide attempt)
John: It's in the past.
Riley: People don't forget about the past.
John: I'm not saying forget it. I'm saying, it's in the past.

Cameron: You've been distracted.
Sarah: I was kidnapped.
Cameron: Which is distracting.

Cameron: (to John) Future John has better information than you do.

John: You feel any different?
Cameron: Yes.
John: Are you all fixed?
Cameron: I don't know.
John: Well just try not to kill any more birds.
Cameron: You're ahead of schedule.
John: With what?
Catherine: What you need to learn.

John: I haven't told her (Riley) anything.
Sarah: I don't believe you.

John: Do you think it's possible for me to know something future John doesn't know?
Cameron: That's hard to know. Seems unlikely.
John: You think it's possible for me to know something you don't know?
Cameron: Are you asking me if future John kept secrets from me? (John nods) I'm sure he did.

Cameron: This is your fault.
Riley: What's my fault?
Cameron: You're the reason that person is here. (Cameron's left hand twitches)
Riley: You're John's sister. You can't keep me here.
Cameron: They don't always like the way I do things.

Cameron: What am I going to do with you?
Riley: I don't understand. I don't know what you mean.
Cameron: Children and family services respond to complaints. Are you a complainer?
Riley: No. No, I never told them anything. What would I even tell them?
Cameron: You don't belong here. John isn't right for you and you're not right for him. He can't see that.
Riley: Stop, please, you're freaking me out.
Cameron: You're unreliable. I don't know what you do.
Riley: I'm just John's girlfriend. That's it.
Cameron: You can't be John's girlfriend. You're a threat. You can't stay here anymore, but I can't let you leave.
Riley: You're John's sister.
Cameron: What am I going to do with you?
Riley: Nothing. You can't do anything to me because you're John's sister. Get it through your head. You're just his sister.

John: Were you going to kill her?
Cameron: I don't know what I was going to do.
John: What do you mean you didn't know what you were going to do? Since when do you not know what you're going to do?
Cameron: I don't know. You should have killed her. She's a threat to you.
John: That is not your decision to make.
Cameron: It's usually not a decision.
John: Well obviously it is this time. And it's not yours. (John and Cameron stare at each other) What's happening with you?
Cameron: I don't know.

Cameron: You tried to fix me. Twice now. It's not working.
John: And?
Cameron: I'm not capable of self-termination.
John: Suicide.
Cameron: I can't kill myself, but you can.
John: Why would I want to kill you?
Cameron: You might have to some day. I've planted an explosive in my skull near my chip. It's a small amount, but it's enough.
visual: John opens the watch to find a set of three buttons, one of them red.
John: Enough?
visual: Cameron puts the watch around John's neck.
Cameron: All you have to do is hit the switch.
John: What would future John do now?
Cameron: Future John doesn't live here. You do.

Cameron works on repairing her arm in a fashion similar to the Terminator played by Arnold Schwarzenegger in the 1984 film, The Terminator.

Sarah: I was wondering when we'd see you again.
Riley: They make you rest a couple days.

In episode 2x13, Earthlings Welcome Here, John finds Riley on the bathroom floor where she attempted suicide.
