It’s important to pay attention to the fact that Luna’s discovery of her magic (the blue and silver she sees when she closes her eyes) and her history are linked. This indicates that as the story shifts more to follow Luna, Luna will break through censorship and forgetfulness all at the same time. When she lies to Fyrian about her tears, it shows that she’s learning from Xan how to ignore sad things and difficult things, as explaining what she saw to Fyrian would likely be very difficult.
