This episode contains a classic causality loop. Fischer is recruited by Skynet because he was in prison for using his computer expertise illegally. His mission is to go back in time and commit the crime for which his younger self was wrongfully sent to prison, thus providing his motivation to work for Skynet.
Goofs: Derek uses his Motorola mobile phone to send a picture message to Cameron. This is impossible for two reasons: the model of phone he uses has no camera in-built to have taken that picture, and that model is not capable of sending an MMS message of any photo to another phone.
The Polaroid John found in former FBI Agent Ellison's home was of his mother, Sarah, and was taken while she was pregnant with John by a kid hustling tourists for money. She ended up buying the Polaroid because she admired his hustle, in the ending scene of the first film, The Terminator. Young John possessed the photo in Terminator 2, so how Ellison obtained the photo is unknown. In the future, John gives this Polaroid to Kyle Reese and tells him she was the best fighter/soldier he ever knew. Kyle keeps it as a good-luck charm, not knowing that John will later send him back in time to protect his mother and also become his father.
Derek: Some people, you can beat them and beat them, and they'll take it. Whatever pain you give them, they absorb it, like it was theirs all along, and you're giving it back to them. You see, deep down, they hate themselves, and they use that hate to eat the pain.
Sarah: I've had some bad luck with shrinks.
Dr. Sherman: Well, you could stop calling them shrinks, that might help.
John: (about Cromartie) He's buried in a hole in the middle of the Mexican desert, and his chip has been obliterated. I think we're pretty ...
Cameron: ... Safe? It's not safe.
John: (to his mom) Oh, God, she's starting to sound like you.
(Sarah is vomiting at the side of the road)
Cameron: Is she pregnant?
John: Why the hell would you even ask that?
Cameron: Kacey vomited when she was pregnant. (to Sarah) You're vomiting. It's morning. That's when it happens.
John: When we see something that's in pain or in trouble or whatever, we try and help it.
John: Something like that.
Cameron: But not everyone would turn the tortoise over.
John: Nope. Some would just leave it there.
Cameron: Some would probably drive over it. Crush it.
John: Yeah, I guess they would. Is that what you'd do?
Cameron: It didn't seem like much of a threat. We're not built to be cruel.
John: Yeah, that's one for cyborgs.
John: How're you feeling?
Sarah: How do I look?
John: Like crap.
Sarah: (takes the medicine John's brought her) Wish I felt that good.
Derek: Maybe I came from a future where it never happened, and now you've come from a future where it did.
Jesse: Is that possible?
Derek: Since I've been back here, I ... I've done things. I've ... I've changed things ... Maybe I changed the future. That's why we're here isn't it? To change the future ...
(Derek cuts Fischer's bond and hands him a burger)
Derek: You hungry?
Fischer: Not hungry.
Derek: You a vegetarian?
Fischer: No. I just … I don't know what's in that.
(Derek takes a bite and hands the burger back)
Derek: Cheeseburger's in that.
(Cameron is riding with her foot draped out the window)
John: What are you doing?
Cameron: Feeling what it's like to get away from it all.
John: I don't think you are.
Cameron: What do you mean?
John: If by feelings you mean emotions, I'm pretty sure you still don't have any of those. And if by feeling you mean what it feels like to have the wind blow through your toes or your hair, (sighs) I'm pretty sure you can't feel that either.
Cameron: I don't think you understand how we work. I have sensation. I feel. I wouldn't be worth much if I couldn't feel.
