Yeah I think I’ll probably stick with the whole “Rey is Palpatine’s daughter” thingy.
Would you rather do that, or reinforce Rey and Palpatine’s respective motivations as described above?
Well, like I said, from my perspective the revelation that she is even more closely related to him should be more shocking for Rey. I suppose it depends on how you look at it though. Is a clone of Palpatine truly Palpatine? Ultimately I believe it comes down to biology in the case of this story.
Honestly, to me it seems the way it originally is in the novel is a dumb callback to Boba being the son of Jango even though he was technically only a clone. I don’t believe Palpatine would claim a non-Force-sensitive clone as his son, personally, so I wanted to lean more heavily into him being a clone over a son.
