The saint said several times in this episode that she wished Alicia didn’t exist and that she wanted to have met the Duke earlier. After everything, she left to “seek her own happiness” and took the book that contains information about her powers.

I think this will be the plot for the next episode.

I think Alicia will try to fix everything, but it will go wrong. The season will probably end with her going to another country (Laval) in search of knowledge and setting everything up for the next season.
