- Col. Jonathan Foster: Those days we spent trapped underground, surrounded by all those books, human beings, gone. But their voices were still with us, thriving. We had hope. They were better times.
- Katarina Jones: Yes, they were.
- Col. Jonathan Foster: You and I were better too.
- Katarina Jones: We were.
- Col. Jonathan Foster: You were the most brilliant woman I had ever known.
- Katarina Jones: But I was also something else.
- Col. Jonathan Foster: Yes? And what's that?
- Katarina Jones: A mother.
- [she shoots him]
- Jennifer Goines: Look. Look before you. Listen! Listen! Listen. The thunder of fallen men! Great men, our fathers, forfeiting their world, their legacy; but not for their sons, for their wives, for their mothers. For their daughters! And when disappearing men die on their sword, we daughters shall make from twelve what men could not. Yes! An army!
- Jennifer Goines: [to a girl] You. You see it. Twelve's not a primary. No, but 13. You're a bright little monkey.
- Katarina Jones: Jonathan. Let me show you the machine, and then you will see...
- Col. Jonathan Foster: Seeing a machine is not gonna make me believe in blasphemy.
- [Jones shows Cole the "machine"]
- James Cole: The hell is that thing?
- Katarina Jones: That is our salvation. The virus is not yet done with us, Mr. Cole. It will mutate, again and again, until not even the immune are left standing. There's only one way to end it. And you are the key. I want to send you back, to stop the plague before it ever happens.
- James Cole: That's impossible.
- Katarina Jones: Nothing is impossible. Difficult, yes. Dangerous. Not impossible. But there will be a price. If we are to reset time, all this before you will vanish. This world will cease to exist. This dark time must be sacrificed, to restore a brighter one. We have no other choice. And if all this disappears, so, too, shall we. And you and I, we will start anew. All humanity depends on us. But they will never know what we have done. And I'm grateful for that. So tell me, Mr. Cole. Will you help me?
- James Cole: Go to hell.
- Col. Jonathan Foster: I, too, wish that the plague had never happened. The great minds lost, your daughter, my wife. But equally, I mourn the loss of who you might've been. I would so have loved to have seen her, instead of this.
- Katarina Jones: And very soon, you will.
- Katarina Jones: Do you remember the first year underground? No windows, no sunshine. I lost all sense of time. I felt as... as though I was choking.
- Col. Jonathan Foster: It was a coffin.
- Katarina Jones: Yes, exactly. And we would sneak upstairs and look at the stars. Cassiopeia. Andromeda. Whole constellations, untouched by disease, oblivious to our suffering. And I told Hannah, no matter what will happen to us... the stars will remain. And I promised her...
- Col. Jonathan Foster: [quoting Shakespeare] "Yet, do thy worst, old Time, despite thy wrong."
- Katarina Jones: "My love shall in my verse ever live young."
- James Cole: I watched the world die, Ramse. Everyone. I watched her die.
- José Ramse: It's meant to happen, brother. She's always gonna die.
