"Do you know him well?" I ask.I am too curious; I always have been. "Everyone knows Four," she says. "We were initiates together.I was bad at fighting,so he taught me every night after everyone was asleep." She scratches the back of her neck, her expression suddenly serious. "Nice of him." She gets up and stands behind the members sitting in the doorway. In a second, her serious expression is gone,but I still feel rattled by what she said, half confused by the idea of Four being "nice" and half wanting to punch her for no apparent reason."
