Spoke and Pinnacle in Death Station
Chapter 14 - "Human Taint"
The battle is over, and prisoners have been taken. Voight and Hanna have been tasked with finding out what the whole debacle was about. The slug-like Cadir are as belligerent as expected, but they have an unexpected reaction to Hanna's presence.

One reason I like science fiction is that it's easier to notice sneakily introduced, provocative ideas about how the world could be different.
