One possible theme is the power of individual perception. In the story, 'Abuela Invents the Zero' might show how the abuela's unique view of the world, as represented by inventing the zero, challenges the existing norms and beliefs of those around her. It could be about how one person's different way of thinking can have an impact on others.
Well, the abuela is obviously one of the main characters. She is the one who invents the zero, so she's at the center of the story's action. There might also be other family members or people in her community who interact with her and are affected by her idea of the zero, but without more details about the story, it's hard to say exactly who else is a main character.
Perhaps she tries to understand Abuela's perspective. Mirabel is a kind - hearted girl, and she may think that there is a reason behind Abuela's actions. So she might try to see things from Abuela's point of view while still feeling the pain of the punishment.
At first, Mirabel might be shocked and confused. She would probably wonder why Abuela would do such a thing to her. She could spend her initial time in prison trying to figure out what she did wrong or if there was some mistake.
One possible reason could be a misunderstanding. Maybe Abuela saw Mirabel doing something that she misinterpreted as a threat to the family or the magic. For example, if Mirabel was exploring a forbidden area in the house where the magic was acting strangely, Abuela might have thought she was endangering the family's future and thus imprisoned her out of fear.
In the fanfiction, Abuela may be under a lot of pressure to keep the family's magic and reputation intact. When something goes wrong that she blames on Mirabel, she kicks her out. Mirabel then has to face the outside world alone. She could encounter various challenges and adventures, which in turn make her grow. Eventually, she might find a way to reconcile with her family and even help save the family's magic in a new way.
She might be heartbroken at first. After all, being kicked out by her own abuela is a big blow. But then she could become determined to prove herself. So she might set out to find a way to show that she is an important part of the family even without a magical gift.
It can create a negative atmosphere. Some fans who love Mirabel might be really upset and disappointed. They may even lose their enthusiasm for the fan community as a whole.
First, the fanfiction platform should have strict content review policies. If such abusive content is found, it should be removed immediately. Also, fans who care about the positive image of the characters can report this kind of inappropriate fanfiction.
One possible reason could be that Mirabel might have accidentally broken an important family heirloom. In the context of the Encanto family, their heirlooms are often tied to their magic and family identity. If she damaged something like that, Abuela, who is very protective of the family's traditions and magic, would likely punish her.
