It could be someone who is jealous of Mirabel's potential. Maybe a relative who feels that Mirabel's new - found importance in the family (even if she doesn't fully realize it yet) threatens their own status. For instance, a cousin who was once favored but now sees Mirabel as a threat.
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.
Song Jiang had both a heroic side and a villainous side. He had played an important role in the Liangshanpo Uprising. He had superb military skills and organizational leadership skills, and was known as a hero with both wisdom and courage. However, his actions were also controversial, such as robbing merchants, plundering villages and other violent acts, as well as eliminating dissidents, murdering companions and other actions for his own benefit. Therefore, from different perspectives, Song Jiang could be seen as a hero or a villain.

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.
Mirabel might be initially shocked and heartbroken. She loves her family and the village, so being banished would be a huge blow. She could cry and try to plead with Abuela to change her mind.
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 could be her mother. Mothers are often the ones who enforce discipline in the family. Her mother might feel disappointed in Mirabel for lying and give her a punishment to teach her a lesson.
She might lose the trust of her family members. In the Encanto family, trust is crucial. If Mirabel lies and is found out, her family may start to question her honesty in the future.
