That’s really cool, it feels much more like an expansion on what Kylo says in TLJ than the theatrical version. Like Shmi, Rey’s parents aren’t important, but she doesn’t need them to be important to this story. I also love the idea of there being multiple chosen ones throughout history, and Rey is just another in a long line of them.
If it’s stated that Rey was chosen by the force to bring balance, I feel like there’s less risk of her turning to the dark, so maybe drawing some connections with Anakin being the “chosen one” and still turning would be interesting. Also, does Rey have a dad if she’s chosen by the force? Do all chosen ones have no father like Anakin? Rey seems to insinuate that she had a father, but she could just be assuming that. Probably not super important but worth thinking about.
