Poor Anastasia gets the shaft (spoiler, I guess)
So not only does Anastasia foil her Stepmother's plan and return Cinderella to her own life, but she puts herself in danger to protect them when Step Mom tries to zap them with the wand. In the end, Cinderella and the Prince are reunited. Stepmother and Drizella end up as servants in the dungeon, essentially leaving her out in the cold. And what does Anastasia get out of the deal? Squat. You'd think that the least the Fairy Godmother could do is make her more attractive. Let's face it, in Disney Princess land, if a gal ain't got looks or magical powers, she's got nothing.
It doesn't even imply that with her only family gone she'll be allowed to live in the castle. Other than a blink and you'll miss it portrait of her with the baker from Cinderella II:A Series of Pointless & Unrelated Stories, but that's about it. Other than that, as far as we know she ends up homeless.
One thing's for sure though; I'm a 36 year old male who knows way to much about Disney Princesses and their affairs on account of a two year old daughter who knows everything there is to know about every one of them.
