- Alexandra Cavill: You leave once, that's a decision. Then, you leave me twice, and then that becomes a choice.
- Melanie Cavill: Yes, I'm choosing to go, but only because there's not much chance of a world for you if I don't.
- Alexandra Cavill: Okay, so... what do you wanna know?
- Melanie Cavill: Everything. What do you love to do? Who pierced your ears? Where you sleep. Will you ever laugh?
- Melanie Cavill: Look, I think you know what your priorities are.
- Andre Layton: Yeah, you want me to run it by you to see if I got it? Protect the science.
- Melanie Cavill: Number one.
- Andre Layton: Yeah, to do that, I'll have to hold off the megalomaniac who created this world and wants to get power back again. And he's already got some supporters on his side.
- Melanie Cavill: Yeah, that's about the size of it.
- Andre Layton: Which leads me to believe that maybe he didn't want anybody to get off this train and recolonize the Earth in the first place.
- Melanie Cavill: Just so we're clear, the success of this mission will be measured in data, not my survival.
- Andre Layton: We will supplement your diet once a week in exchange for parts.
- Joseph Wilford: You seem like a capable leader. Amazing what you've learned in such a short time. I'll consider it.
- Andre Layton: I'm so sorry, Josie.
- Josie Wellstead: For what? Falling back into Zarah? I was dead.
- Andre Layton: Yeah, but you're not dead. You're right here.
- Josie Wellstead: Look at me, Layton. I don't care who the mother of your child is. You know who did this to me. Melanie.
- Andre Layton: I had to make the alliance. It was the only way.
- Josie Wellstead: You sacrificed 35 Tailies to her plan. The people that I convinced to fight.
- Andre Layton: I wanted to die with them.
- Josie Wellstead: And now you've given them nothing that we promised. And your leadership is in question.
- [First lines]
- Joseph Wilford: [narrating] We all know how this ends, don't we? Everybody dies.
- [chuckles]
- Joseph Wilford: That shouldn't be a surprise. So what's an old white man to do with a lifetime of knowledge doomed to erasure, except wield it like a sword? Great men say balls to death. My crew respect that.
- [Wilford makes his morning announcement to the crew of Big Alice and walks Icy Bob to the laboratory]
- Joseph Wilford: Apocalypse isn't so bad, really. If you can just muddle through, show a little ingenuity, people line up for tickets to the only show in town - aboard Snowpiercer. My train. All 1,034 cars long.
