There's nothing to hold against FL's who are a little obtuse, but Missy here runs the show full on dissociating. Which is fine really. If you're surrounded by buffoons you'll cope however you can, but the story kind of ... runs along, runs her over, and calls it a day.
Her family steals her inheritance, treats her like garbage for years, and then frames her for crimes they committed. She forgives them like it's cool, and they get away with everything. I guess that I'm a vengeful human being because I don't play that way. Meeting out justice to unrepentant wrong doers is actually an evolutionary imperative. Species that don't practice this die out.
