There's an old, old grudge preventing her from moving on; it's been so long that even she can't remember exactly what it was, but she's still mad about it. She's not one to play nice at all, and you're better off avoiding her than ever trying to interact with this ball of anger. Even now, she's still looking for the reason why she's angry... and may require help in achieving her goals from her stern yet aloof handler. Though... every now and then she's not angry, and she turns out to be quite the skillful huntress... those moments are few and far between.
