I watched the whole movie, cried at the end cause it was sad, but I feel so stupid after knowing this. I did find this out during the
movie so it's not like I just found this out. But I like to jump to conclusions, I don't do it in purpose, but I thought that Marnie and Anna liked each other, I was later shocked and embarrassed to find out that Marnie was her grandmother. IDK what magic is behind it, IDK if Marnie is the incarnation of her grandmother or a younger spirit of her grandmother but I was dumb😅
