This theory explains everything in encanto: Mirabel's family have been hiding something from her: She's ADOPTED! This is why Mirabel didn't get a gift- she isn't actually part of the family I personally don't fully believe this theory (I'm 15% believing) but who knows? If Disney made a sequel could the sequel confirm this?
I didn't make up the theory I heard it somewhere else on scratch I think but yeah and the pictures and character names belong to Disney Comment if you have any other theories or want to say anything about this project.
