Betray them or no? The argument for not betraying them is that they might be possible to talk around anyway and if her effort to summon a secret rescue mission is discovered it might make that less likely. The argument for betraying them is obviously that right now she has no leverage at all and also no way to make sure that word of this situation reaches anyone who could do anything with it, and if there's someone then that's much better.
They might be reading her mind.
She doesn't think so. Mhalir would have to be a very good actor. But he's another species, it's hard to sense peoples' motives even if they're only an Elf or something and the thing he is is stranger than that -
- why give her the opportunity, if he suspected her -
- if they catch her, things will go much much worse than they're going right now. They might dispose of her entirely and kidnap someone more cooperative. They might have already done that, taken hundreds of prisoners, they might be checking who is the easiest to work with -
- when you're uncertain about lots of things, don't break the rules -
- she wants to, but that's not an argument, you can't let the desire to be clever and get away with something make decisions about entire worlds -
It's not like it's safe to be cooperative. But they clearly get something out of having her cooperative, or they could have done this with threats from the beginning. It seems likely that if she keeps things superficially cooperative, they will too. And that means there'll be better opportunities to escape later.
She doesn't try anything. She walks quietly to her desk and gets her spellbook and walks quietly out.
