Back in chapter 6, about 104 pages ago, I thought to myself, "That person will turn out to be the villain." And then I dismissed the thought because it seemed so obvious it had to be misdirection. But no, the more I read the more convinced I am. That person actually is the villain. Or one of them, at least. And I know exactly who they are, since they're obviously not who they pretend to be. All the signs were there to be read back in chapter 6. Obvious villain is obvious. Disappointed reader is disappointed.
