I like the prophecy angle for Rey Nobody, I just think you’d have to really get the point across that she could become evil like Anakin, as telling someone that they’re destined to destroy the sith doesn’t really connect to Rey’s inner darkness immediately. I think that could play great off of Rey’s fear of not being able to live up to the legend of the Skywalkers, though. I also really like the originality of the dyad concept, focusing just on that and maybe connecting the dyad to an ancient sith prophecy involving the rule of two would be an interesting inversion of Anakin’s arc, and could explain that Rey’s link to Kylo’s mind allowed her to intrinsically use his knowledge of the force in previous movies.
