... so, Ain is the villain of the novel. A villain with "no weaknesses". How did he get defeated in the original, I wonder.
More importantly, there's no way this isn't coming back to bite later. He now has 2 weaknesses.
Also, I can't help but think that this is the sort of family dynamics that gave birth to Freud's child development theories, what with a burgeoning Oedipus complex and a father vicious enough that fear of castration almost seems reasonable.
@Asean makes me curious what the general tone of the novel was that she can't recognize the necessity of this training. She also has no idea that the house has literally been under attack since she "arrived".
Family, and other types, traditions can be awful and wrong. So I don't think that's a reason for her to shut up and sit down. but it should be an informed decision and frankly, other than what she's read of the novel, which she has specifically said didn't cover any of the Chase family circumstances, she doesn't know jack.
