- Dr. Jeremy Stone: So, you're saying they survived Andromeda because they had the same level of stomach acid? That's brilliant.
- Dr. Angela Noyce: I think a linear time frame is a key part of what means to be human. If our really important choices could be sampled like a box of chocolates, then our decisions would lose their meaning. What would be at stake?
- Major Bill Keane MD: [to Jeremy] Charlene was right. There's never been anything like Andromeda anywhere on the Earth. This is terra incognita. This is alien.
- General George W. Mancheck: I need to know. What have you got to fight this thing?
- Dr. Jeremy Stone: Nothing. At this point, not a single thing.
- General George W. Mancheck: We suspect a biological agent now code named Andromeda. Whatever Andromeda is it killed those two soldiers so quickly they didn't even have time to jump out of their vehicle.
- Private Brooks: It's like a war zone.
- Private Connors: Tell me I'm not seeing this.
- Private Brooks: This town is full of bodies.
- Kyle Tobler: Over here! Over here! Help me, men! You've got to help me!
- General George W. Mancheck: What do you need, Stone? Tell me what you need to kill this thing, and I'll get it.
- Major Bill Keane MD: [to the President] Andromeda's mutation rate is increasing. There's a very real chance that we won't be able to contain this.
- Dr. Angela Noyce: [to Jeremy] Most die immediately with exposure. Those that don't exhibit violent behavior within minutes.
- Major Bill Keane MD: You're saying it thinks?
- Dr. Jeremy Stone: I'm saying we need to consider the possibility and act accordingly.
- Major Bill Keane MD: [to Jeremy] If you set out to deliberately exterminate mankind, you couldn't do better than Andromeda.
- Ed Dewitt: Are you religious man, Chuck?
- Charles 'Chuck' Beeter: Sir?
- Ed Dewitt: I don't mean every four years. I mean, do you have faith?
- Charles 'Chuck' Beeter: Yes, sir.
- Ed Dewitt: Then you can pray.
- Wildfire Computer: Wildfire is infected. Wildfire Labs is now initiating lockdown procedures and beginning countdown to auto self destruct.
- Dr. Jeremy Stone: What's happening?
- [last lines]
- Dr. Jeremy Stone: We would seem to have been successful in the short run, but it's probably fair to say whoever it is, we've gotten their attention. What happens next is anybody's guess.
