"Send people who have fairies who understand that brainwashing is harmful," says Mira. "But I don't think arresting her will fix it. The fairy could be misinterpreting Kelsey somehow and creating this behavior more or less of her own accord - but the consistency means that Kelsey isn't trying to stop her, even if stopping her was just the bare minimum of not calling her up and asking her for things anymore, and the way Kelsey acts means she approves. I think the best thing you're going to be able to do is kill Kelsey and hope whichever of the daughters is her heir isn't the same way."
