There's definitely some interesting potential here! Especially since outside of like, mind-altering circumstances Beatrice is at a point where she actually doesn't really want to like, do much to Ange outside of be weird and mysterious and maybe harass her a little. She's from a canon point where she's basically given up on the game since the person she most wanted to understand it has failed to do so and so while she's still all board the revenge train, Ange is not actually on the list for the most part because she was too young to be a blip on Beato's radar.

So while she's not going to make an effort to reconcile barring other circumstances (Battler showing up, Sayo trying to get her to play nice) she's not actively hunting down Ange to torment her. At most, she's annoyed that Ange interrupted her game once or twice! So while she talks a big game and will say a lot of horrible stuff, the desire to actually follow through and do anything to Ange isn't really there. Even though she's still cruel and taunting to a stupid degree.

If Xerxes will remind her of Ronove, she'll probably want to try and become closer with Xerxes if only because she is a deeply lonely person who wants connection with others but is often too proud to come out and say it. Not to mention she misses her magic friends. I'll poke you on plurk! I'm gravenrose.
