I've beat Knight. Fuck it felt good, the last run was particularly smooth, I had all three members of Fuck Squad standing for the last attack. But I've also noticed couple of important things:
1. Pretty sure it was Kris who struck Susie and Ralsei down. Not 100% sure, but I would bet good money on it.
2. However, when Kris and Ralsei are left alone together after the fight, Ralsei says "You were very brave, but our struggle is only beginning." Since Ralsei must be aware that Kris is working with Knight, it's a good indication that they both are not on board with what Knight is doing, and are planning to defy her.
