Looks like we reached the part where grandma officially attacks Calypso
Spoiler!
She challenged Calypso in a duel and easily accepted her defeat. She was banished from the territory. Calypso won the fight easily with the help of Echion because he bring out the power she had in the previous timeline.After the fight, Calypso didn't have the time to enjoy her victory because Tooth told Calypso that if she doesn't stop it will ruin Echion. Because the power she was using is the power meant to help him grow. Echion deliberately did this, so that Calypso will not pay attention to Ocula.
I like to post spoilers for the stories I find interesting because I don't have much time to read novel due to busy schedule you will find me in most romantic historical manhwa comment sections
