Oh yeah, that is a good point Jar Jar. It does really make the whole spirit transfer thing kinda complicated.
I honestly believe the early leaks said that the Palpatine we see in the film was originally just meant to be his original body, somehow recovered from the Death Star. It’s dumb, but at least the spirit transfer thing doesn’t have two rules all of the sudden. I also don’t know if spirit transfer was a thing at all in the first version. And as far as I’m aware, it was always his plan to drink their Dyad milkshake before the reshoots. It wasn’t a surprise to Palpatine.
The early version also has Palpatine tell Kylo that he’s dying and has been grooming Kylo as his successor. And he wants Kylo to bring Rey so they can turn her and have them begin a new Sith dynasty. Palpatine is also the one who tells Kylo about the Dyad. Which makes sense, since the theatrical version never explains how Kylo knows about the Dyad. Of course all of it is a ruse to get them to come there together to allow him to drain their life Force.
Anyway, I don’t think any of these dialogue changes would drastically improve the film. At the very least they could nudge the film in a more logical direction. It’s just a matter or figuring it out what’s the most effective change with simple, unobtrusive edits. You can argue the theatrical film potentially makes sense as-is and none of these changes make a difference. I just wish it was less convoluted, which is what I’m trying to figure out.
