River Tam
- [River finds Book reading the Bible]
- River: Don't be afraid. That's what it says. "Don't be afraid."
- Shepherd Book: Yes.
- River: But you are afraid.
- Shepherd Book: Yes.
- River: You're afraid we're going to run out of air. That we'll die gasping. But we won't. That's not going to happen.
- [Book looks at her hopefully]
- River: We'll freeze to death first.
- River: [after Simon looks at her to see if they found out his birthday from her] "Day" is a vestigial mode of time measurement based on solar cycles. It's not applicable... I didn't get you anything.
