RogueLeader, you always have excellent ideas for small tweaks to lines which totally change their meaning. I really like “I saw what we will become. We won’t just have power. We’ll have his power.” (maybe I’ll try to see if I can put it together). The ideas that you and others have been having recently to further separate Kylo from Palpatine are excellent, I think, and a good way to bring him a little closer to TLJ Kylo and also make his redemption better fit his overall plot in the movie.
I admit that I am personally biased against Testing’s (and I suppose the official) interpretation of Palps ever wanting to possess Ben in a Rey Palpatine edit, because if he could just possess anyone regardless of their genes, why’d he bother putting all that effort into growing force sensitive clones of himself, or strandcasts like Rey’s dad? I also don’t really like the idea he ever intended to possess Luke in ROTJ - the existence of Exegol and his clone bodies there already help justify his seeming willingness to die in ROTJ; we don’t need to make it weird. In a Rey Nobody edit, though, I suppose you have to suggest he could possess either of them since there’s no obvious distinction.
