Can we all talk how before Alma steps into the river she wears her mourning shawl but then she takes it off?
It such a great symbolysm! For Alma's suffering finally getting recognized. The fact that she isn't alone anymore but also ready to grow beyong what the pain of loss made her to be. Letting go of the past, being ready to change and move to acceptance stage of grief (as she was stuck in bargaining for years)
I like that she does pick it up and put it back on after they leave the river, but every time after that we see her without it. It's one of the few things she has left from her time with Pedro and leaving it entirely wouldn't be right for the story or the character.
She's never going to stop mourning Pedro, but she's learned to set aside her sadness to be more present with her family, only taking out the shawl and mourning when she needs to, and possibly learning to associate the shawl and what it reminds her of with the happy memories rather than her mourning.
