So based on a new art of Star Wars book, Disney is trying to sell something that nobody is ever going to buy: That Rey was planned as a Skywalker from Day 0.
From the book:
The Art of Star Wars: The Rise of Skywalker describes a meeting of the Lucasfilm Story Group that took place in May 2014. "I like the idea that she's going to be our Skywalker," Lucasfilm's Pablo Hidalgo observed, "but she's not a Skywalker. Then, for our purposes, 'the Skywalker' is really a metaphor. It doesn't have to be something that's directly connected to blood."
