The beginning parts of the chapter do a good job of setting the scene, and I think the repetition actually helps to establish that Kai's actions are routine, a product of training and experience. Likewise, the callbacks to the previous chapter help keep the focus on what Kai needs to do and what he's up against. The garrow is creepy, certainly, and you paint a vivid, fetid picture with the way it moves and screams out in the woman's voice.
This feels like it could be a complete piece, rather than a fragmentary passage, although it's still short. I read this part out of order, so I know how the next piece goes. More comments there.
