I enjoyed the chapter, (though I do hope we see Hex again). I figured that part of what would happen was seeing that the Nothroi were not the 'savages' the Legion thinks they are, but that's something to be expected when there is a war, so though I kind of expected it, it makes sense. And I like that the Nothroi are not what we've been led to expect so far (and that within them are opposing elements, some of which likely led to how the Legion soldiers think of them).
I am interested in where things are going to go (for example how Jhuz will get away within another chapter or two), but I will also say that I hope that Jhuz doesn't go down the whole 'they're not savages' route, and end up changing sides. I don't see that happening at this point, but it's just something I always worry about when these kinds of situations happen.
I think that so far you're accomplishing what you set out to do (making Jhuz's imprisonment have an impact). While I personally wasn't too shocked by the realities of the Nothroi, it felt like Jhuz was pretty surprised, which is what I think your goal was.
And of course, I want to find out more about what the aim of the Chell is.
