I know you're not terribly concerned with grammar, but I noticed this three times in the first paragraph. So, a rule: "It's" as you've used it in the first paragraph is incorrect. "It's" is a contraction, "it is". "Its" is possesive, and the term you want to use here.
The action scene at the beginning of the chapter is falling a little flat for me, I'm afraid. I think it's because I'm not really getting any emotion out of it. Whether that's fear, panic, anger... I'm not really getting any of it. Even when Will is awed by the effects of the combat pod, you tell us rather than showing us.
When you mentioned "white people", at first I thought you meant caucasian and that your characters were of a different ethnicity. I see now that you're actually referring to albinos, but it was a bit jarring.
These thralls must be pretty fragile, since Abby is having an extraordinarily easy time abusing them. It feels a bit like a one-sided fight, actually. Why is she so much more proficient at this than Will seems to be? Also, Will eating the pod when he doesn't know what it does to him seems like a really stupid idea. Maybe it's a desperate gambit, but it's still dumb. Maybe I'm just not getting the desperation that I'd need to buy this as a believable action.
In the middle of the scene you completely switch points-of-view, flitting from Will to Abby. I hesitate to say that you "can't" do this, exactly, though traditionally third-limited POVs don't change other than between scenes or chapters. If you're going to do this, I'd at least suggest some sort of in-scene transition from Will to Abby (he felt it starting to take effect in some way); that would also help the other problem I had here, which was that Will took the pod and then we seemed to forget about him for a while, instead describing the thralls crawling all over Abby.
Honestly though, I think I would rather see this chapters stay wholly in Will's point-of-view. The switch between POVs doesn't seem particularly necessary, and I think watching Will see himself turn into a stone statue would be way cooler. (Wow, that sentence sucked. But you know what I mean.)
I like that Will's stone-statueness wore off before he could help his father. And I like the fact that he fled the village, realizing there was nothing he could do. Or rather, I like the fact that he made the choice, though the way it's written right now I don't think it quite clicks. What I mean is that I think we need to see a little more of his desperation that leads him to making the decision. (Not TOO much, mind you. A line or two might help, even.) For example: is he realizing that there's ntohing he can do and will only get captured if he tries to help? Or is he realizing that he can be of most use if he goes to protect his sister? Also, the line "he sighed and started up the trail" seems awfully mild here for what he's actually going through. This is, or has the potential to be, a tremendously difficult decision, and I think with just a little bit of tweaking you could really make it have an impact on the reader.
Actually... I think I could take my whole critique and sum it up by ripping off quoting something Recovering Cynic said: The storyline is good, but the delivery needs some sprucing up. His points about the writing were good ones, too. Of course, that's the sort of thing that can be taken care of in a much later draft. I wouldn't be terribly worried about it at this point.
Hamster makes some good points as well, that I partially agree with. I didn't care too much about Dezkin getting captured, other than the fact that it's obviously not good if The Bad Guys get ahold of him. That's potentially problematic. Less problematic, as far as I'm concerned, is that we don't know the villagers; Will knows them, so in my opinion we don't need anything more than his connection to them to get us to feel for them, or at least for Will's loss. Of course, that means that Will has to emote much more than he currently does. He doesn't need to beat his chest and scream fruitlessly at the uncaring skies (or whatever) but we do need to get a little more from him.
That said, especially once you've gone back and added some emotion to it, this chapter has the potential to be a formative moment for Will, a turning point. If you want it to be, of course. This kind of guilt and remorse can really drive a character. Or break him. Or whatever you want it to do.
