One important bit from Star Wars: The Rise of Skywalker that pertains to this interpretation specifically was Hayden Christensen’s voice cameo at the end before Rey defeats Palpatine.
In the recently released The Art of Star Wars: The Rise of Skywalker book, Carter explained that Rey taking on the Skywalker name, coupled with her defeat of her grandfather, Palpatine, brought balance to the force.
The whole Rey Skywalker thing proved to be a divisive way to end the Skywalker saga, that much is certain.
The idea of the Chosen One who will bring balance to the Force is something that has been a prevalent issue in the Star Wars franchise.
