Luna’s list of things she knows are true suggests that she’s more interested in telling and discovering the truth than she is in hiding things, like Xan does. However, because Luna can’t retain anything to do with magic, she’s unable to figure anything out. Therefore, she cannot feel safe or comfortable asking Xan about her origins. While the reader knows that Xan wouldn’t be able to tell Luna anyway without Luna going into a spell, the fact that Luna doesn’t know this makes it even more frustrating for her.
