First, though, the monster tells Conor three stories on three separate nights. Though they seem a bit like fairy tales, the good guys turn out to be the bad guys, and vice versa. And there's a sinister twist: when the monster tells the stories, Conor acts them out in his own life, then realizes what he's done only after the monster disappears. One leads him to wreck his grandma's living room, and one causes him to beat a schoolmate so badly the kid goes to the hospital with broken bones and teeth. However, when Conor does something awful, nobody punishes him, because they're all walking on eggshells around the kid whose mom has cancer. It's easier just to pretend he doesn't exist.
