Daisy Ridley on the evolution of Rey’s lineage
https://youtu.be/6ELygTJL8Xg

Gad: Have you been keeping Rey’s secret from the beginning. Did you know about the parentage?

Ridley: No. At the beginning there was toying with an Obi-Wan connection. There were like different versions and then it really went to that she was no one. Then it came to Episode IX and JJ pitched me the film and was like Palpatine’s granddaddy and I was like “Awesome!” Then 2 weeks later he was like “Oh we’re not sure.” So it kept changing. Even while we were filming I wasn’t sure what the answer was going to be.

Edit: This puts the line uttered by Kenobi in TFA into perspective, “Rey…these are your first steps”. It is likely that there were versions of TFA were Rey was explicitly related to Obiwan, and that this line is a remnant of that.

And yeah, it actually looks plausible now that the whole “You are a Palpatine” thing could have been recorded a few weeks before the release in Adam Driver’s closet…
