For Xan, even though she knows she made a grave mistake somewhere along the line, it’s more comfortable to tell herself that Luna simply won’t be magical. In this way, Xan not only keeps Luna from learning anything about magic; she also keeps herself from puzzling over how to deal with Luna’s erupting magic when Luna does turn 13 and needs to know the truth. This shows that Xan’s desire to forget sad or difficult things doesn’t just harm her—it harms everyone Xan comes into contact with, if only by accident.
