Personally, at this point, the whole mess about how Palps returned is part of the fun to me.
Is he a clone? Is he a ghost? Is that his original body? How he’s still alive? Is he just a walking corpse? Is he now a space lich or something? Is he a metaphor for how the movie industry just insists in the same ideas over and over for decades until they rot away and become only a shadow of their former selves? Who knows?? Who cares???
I know it’s still messy, and perhaps I just got used to it, but well, it’s a movie about space samurai wizards, so I think as far as this edit can go, Palpatine’s returnal it’s enough for me, more would break the fun, it doesn’t answer clearly but it doesn’t leave us in the dark like the theatrical cut (thanks Poppa)
