Alice has spent her life feuding with people, on the internet and in real life. Her own family have nothing to do with her, only her younger brother has anything to do with her, and he has an ulterior motive. She repels people with her behaviour until they have to cut contact with her to protect themselves.
This feud is on another level. Her possession, Ioan, legged it out of her clutches, and despite everything, has slowly and very determinedly, extracted himself from his life. He is valiantly trying to do the best for his kids, but he is absolutely resolute. She cannot bear to be bested by anyone, particularly by people she sees as not being the same level as her. B and I are solid. IG is a different man to the Ioan of a few years back. Even if B wasn’t with him now, he has seen how differen is, how it is meant to be, and Alice can’t stand to lose. It is literally driving her crazy.
There isn’t going to be any great redemption story for AE. She is too far gone.
