I’m pretty certain that’s similar to what RL (or somebody else?) said a few pages back. I think it’s the best way to take things in a Rey Nobody edit. Their dyad forms because they’re both related to Anakin - Rey is “a” chosen one and Ben’s grandfather is “the” chosen one. Although I’m pretty sure that making it so Palpatine orchestrated both the creation of Anakin and Rey by “influencing the midichlorians” would make the kiss at the end even worse than Luke and Leia’s.

You’re probably referring to that canon comic which showed Palpatine behind a pregnant Shmi, but I believe the comic writer later stated that was just what Vader suspected to be the truth, and not reality. It’s best if both Anakin and Rey were gifted their powers and created asexually by the cosmic Force, rather than Sith trickery.
