T-888 Terminators are too heavy to swim.

Cameron's sensors are good enough to detect a .93mm shift of the foundation over a period of one year.

John: What are you doing?
Cameron: This is the absolute center of the house.
John: Excellent, good work.
Cameron: The house is moving.
John: What?
Cameron: Moving, the east by southeast section of the house is moving.
John: Really, where's it going?
Cameron: Down, at a rate of .93 millimeters per year.
John: And what, does that affect the security system or ahhh, sight lines for the night scope? How does this affect the safety of one John Connor?
Cameron: It doesn't, but next summer we're going to have to repaint.

Cameron: (peering up the fireplace) There is something alive up there.
Sarah: Is it something that can hurt us?
Cameron: It's a bird, I'll kill it before it flies away.
Sarah: No.
Cameron: Maybe later.
Sarah: Maybe never.

Sarah: John's gonna buy computers today, go with him, do not let him out of your sight.
Cameron: Is there anything I need to know?
Sarah: You need to know not to let him out of your sight, and don't touch that bird.

Cromartie: (speaking to Michelle) In 1897 James Atkinson invented the mousetrap. It's spring slams shut in 38 thousandths of a second. It is a record that has never been beaten. It is hard to build a better one.

Riley: So, coming back to school?
John: No, no I don't think so. My mom wants to uhh, home school me for a while.

Michelle: What are you doing here? I know he brought you, you didn't have to come.
Sarah: 'Cause I did.
Michelle: For Charley?
Sarah: I just did. Frankly I thought it'd be easier, I thought you'd be dead.

Sarah: Doesn't make any sense, he messes with the car and not us. We're human, we're not that hard to kill.

Michelle Dixon: It was a fake? This whole thing was a fake?
Sarah: He wants John, he doesn't have to kill us to get to him if we're stuck here with no way back. I should have known when you weren't dead.

Catherine: My late husband and I have spent three years and twenty million dollars trying to reverse engineer this technology. We've not been successful, yet.

Ellison: What do you want from me?
Cameron: I want what you want Mr. Ellison, I want answers. But more than that, I want you to help me find another one (referring to a Terminator).

John: A little help!
Cameron: I don't swim.
John: Yeah, I just figured that out.

The gas station and fruit stand shown in the desert is the same one at the end of the original film, The Terminator.

Catherine: Red Valley New Mexico, eight years ago. Twenty two witnesses report seeing a man with some kind of robot leg, try to kill a boy later identified as John Connor.
Ellison: John Connor?
Cameron: Son of Sarah Connor.

The events Catherine refers to occurred in episode 1x01, Pilot.
