Poor Old lady TBH, she just want an apprentice/train him..... granted her way are wrong and she threatened the heroine, but she should've been captured instead...
Edit: I got several @ for this comment, but at the time i made this comment, I honestly forgot about the child assault part... but I didn't think she raped him, since in a flashback, he got rescued before she got any further iirc, but I could be remembering wrong....
