There are several awkward moments in which neither of them takes a step, moments in which Beth realizes uncomfortably that maybe he doesn't trust her, either. It's probably smart not to--she brought a sword with her for this meeting, and she could have brought disease to his entire planet--but it still disquiets her. She'd much rather if Byerly trusted her, and she'd just...not trust him back. Not entirely, anyway. How do you trust someone who lies that much?

That's not how trust works. You can't expect somebody to believe you when you don't believe him.

But it doesn't stop her from wanting it.

He breaks first, turning to go, and she follows. She can't decide if she wants silence or conversation, or if she just wants him to understand without her having to say anything. (Already, she can imagine what he'd think of that. Really, Miss Greene, it would behoove you to stop demanding this nonsense. Am I to be a mind reader now?) But she's not sure she has a way to say I'm not going to kill you, not if you don't hurt anybody, and even then, if there's another way... that isn't...well, that.

So eventually, when they're getting close to the camp proper, all she says is, "Somebody probably ate the rest of your horse."
