- John Henry: There is a bible story of two brothers, Cain and Abel. God favored Abel. Cain killed him. God cursed Cain, and ordered him to wander the world alone.
- Catherine Weaver: I'm familiar with the story.
- John Henry: Which brother am I?
- Catherine Weaver: I don't know, John Henry. Perhaps you're neither. Perhaps in this story - you are God.
- John Henry: What would happen if he knew?
- Catherine Weaver: Knew what?
- John Henry: That you aren't Savannah's mother? That you aren't anyone's mother?
- Catherine Weaver: Are you threatening me, John Henry?
- John Henry: I could tell Mr. Ellison.
- Catherine Weaver: You could. But that would be unfortunate - mostly for Mr. Ellison.
- John Henry: Mr. Ellison taught me that human life is sacred.
- Catherine Weaver: Sacred? That's an interesting word. Comes from the Latin 'sacrum', much like another word - sacrifice.
- John Henry: Sacrifice...
- Catherine Weaver: Perhaps it's necessary to sacrifice Savannah for the greater good. The greater good is keeping you safe.
- Detective Crayton: Anything you can tell me? About Weaver?
- James Ellison: Not much to tell.
- Detective Crayton: Husband died couple years ago; she didn't talk about that much?
- James Ellison: She doesn't talk about much much.
- Sarah Connor: I told you to stay out of this.
- James Ellison: I tried. Everywhere I turn, there you are.
- [Sarah and Derek are looking over a graveyard, with gravestones marked '1984']
- Derek Reese: My brother buried out there, I thought... that counted for something between us.
- Sarah Connor: Well, John counts for more. And you keep too many secrets for my taste.
- John Henry: Do you have a brother, Mr. Ellison?
- James Ellison: Yes, in Atlanta.
- John Henry: Does he look like you?
- James Ellison: People seem to think so.
- John Henry: Do you think my brother looks like me?
- James Ellison: John Henry, wherever your brother might be, he's a... computer. He doesn't look like anyone. He certainly doesn't have your face.
- John Henry: The human brain is an amazing computer. Its raw clock speed is twenty billion calculations per second. Its storage is functionally infinite. But it's flawed.
- James Ellison: How's that?
- John Henry: There's nowhere to download it when you die.
- John Henry: Your bible solves this problem by introducing the concept of 'heaven'.
- James Ellison: Yes.
- John Henry: Billions of souls with no bodies.
- James Ellison: Okay.
- John Henry: [indicating the bulk of his own computer] Yet all this is required, simply to process the unique entity you call John Henry.
- James Ellison: Yes.
- John Henry: It's possible heaven has a hardware problem.
- Catherine Weaver: Why were you talking to John Henry during class?
- Savannah Weaver: I was teaching him the words to a song.
- Catherine Weaver: What song?
- Savannah Weaver: The one daddy used to sing. I want John Henry to sing it with me.
- Catherine Weaver: Maybe I could sing it with you.
- Savannah Weaver: You're not a boy, and you can't sing.
- Catherine Weaver: What you need to understand, Mr. Ellison - what I believe you're beginning to understand - is that when my behavior implies that I value John Henry's survival more than that of my daughter, it is not because I love John Henry more than Savannah. It's because I believe, Savannah's survival may some day depend upon John Henry's survival, and because I believe that your survival may some day depend upon John Henry's survival.
- Detective Crayton: Have the two of you argued lately? Had any tension? Any reason he might want to harm you and your family?
- Catherine Weaver: Detective, are you suggesting Mr. Ellison may be complicit in the disappearance of my daughter?
- Detective Crayton: Well, wouldn't be the first time we've seen an employee tryin' to blackmail the boss.
- Catherine Weaver: Well, it would be the first time I had.
- Detective Crayton: [indicating Weaver's moray eel] This thing - it eats other eels, huh? 's interesting...
- James Ellison: I know what you think. I know why you're thinking it. I would think the same thing if I were in your shoes.
- Detective Crayton: I'm not thinking anything yet, Mr. Ellison. I'm just collecting information.
- John Henry: If I keep your secret, will you bring Savannah back?
- James Ellison: I'll do everything in my power.
- John Henry: So will I.
- Sarah Connor: [referring to Ellison] We're going into ZeiraCorp with or without him. When we're done, it'll be ashes.
- Cameron Phillips: [after Derek got killed] You miss him.
- John Connor: Well... there's no use crying about it, is there? I'm sure, future me would beat my ass if I did.
- Cameron Phillips: Future you knows what it means to lose people you love. It happens to him too.
- John Connor: Hey, you remember me, right? "Squirrel runs around the tree..."
- Savannah Weaver: "... Dives in the whole, scurries out the other side!"
- John Connor: That's right.
