Well, if he's really with a cult—and I don't see why Heather would lie about that—it makes sense he'd have strong religious opinions. Especially if they clash with what he's been taught.

[God, he doesn't know, though. He assumes that's what cultists do. Argue about religion. Make dread sacrifices.]

Heather's still a teen I think, yeah. I can't imagine being that young, stuck here all by yourself... So I guess she took a liking to you?
