Alma Madrigal – in my opinion, one of the most underrated (and undervalued) Disney heroines, and it’s her who is a main character of the story, to me.
In less than year of her life, this young woman has met the love of her life, married him, had children, and lost him to violent death (while seeking refuge and being exhausted from childbirth of three), and after that, for 50 years she lived with a trauma of witnessing her husband killed before her eyes, while raising triplets, governing entire growing village, and dealing with unpredictable mysterious magic. (And, while she, probably, was helped by whole community in the course of it, she, despite being very young and remaining such for years, never remarried again, staying fairly independent.)
The magic that was given in a cost of loved one’s life, and one that serves as a mean to assure that nobody, Alma herself of her children, never have to revive experience of seeing one of them giving away their all to save other. And one way to honor and maintain that miracle is to teach each new generation to respect its origin, use its gifts only for good and not to mistreat it, so no sacrifices will be needed to keep family together. And, by tragic irony, it turned that her children and grandchildren are willing to do exact thing they were supposed to be prevented from, for the sake of keeping miracle alive, rather than taking care of communication and open support of each other to be strong together. And even then, for years all of them never tried to abuse their, potentially dangerous for the most part, magical gifts, remained kind-hearted and loving to each other, even if not all of them mastered ability of expressing their love in constructive ways. This is, I think, a testimony of Alma being a fairly good mother and mentor figure in highly irregular situation she was put in without any clue how to handle.
In early versions of story draft, she was written as even more legendary figure, apparently having built Casita in one day all by herself while heavily pregnant(!), and such, but, magic aside, her story being more grounded works better for giving her character empathetic angle and highlighting how, struggling through imperfections and uncalled experience, she managed to stay strong and reliable and earned deserved peace of mind in the end.
