I think it was handled quite nicely. I liked Ferris's line that she won't dodge anymore and it's up to Ryner how it all will end. Considering his general level of power, I think she made the right call by deciding he would have killed her a long time ago if he really wanted. Whether that was counting on the Ryner side of the dual personality to actually be able to make decisions or perhaps believing the Alpha Stigma wouldn't want to kill her either, is another question.

In any case Ferris managed to show a considerably gentler side of herself to balance all those whacking scenes. I also got the feeling she didn't do what she did only for the sake of the job at hand but she genuinely appreciates Ryner's company. Good for him.
