Alastor finding kinship with women for being an oppressed class in society. Alastor being protective of women because he had seen how life treated his mother and it has made him resentful, and he happily, enthusiastically leaned into erasing the sources of his resentment.
Alastor noticing Charlie’s unbreakable spirit because he can relate to it. Because he knows how it is to move within a system where the odds are stacked against you.
At first he wants to see how badly she will fuck everything up. Because she is a naive, privileged, sheltered woman trying to *change* something she can’t even begin to understand. But she refuses to fold to humiliation, and she is dedicated to learning, improving her understanding so she can help her people. And despite his embittered view on humanity, he finds himself wanting to see her succeed.
Beneath his questionable motives, he becomes her most valuable advocate. He challenges her, shows her the cynical aspects of the work that falls into her blind spots. He becomes her devil’s advocate. He makes her better because he doesn’t coddle or baby her. His protectiveness over her and faith in her abilities shows in his actions and how he talks about her when she isn’t there.
