If there was one good thing that came out of all this, it was that Luna had come to understand the intent behind her mother's actions during her time alone.
Luna's mother had probably noticed the way her personality was taking a turn for the worse. Clearly, the message she had gleaned from all those lessons was not the one her mother had intended for her.

If her mother had told the truth about everything being an elaborate scheme against her family, she was sure she would have tried to stay behind and fight.
