Lol, I’ve thought about that a lot Burbin!
I find the idea of the Sith consciousness really interesting. The implication is that “Palpatine” as we know him is really one of dozens of Sith identities that exist in him, starting with Darth Bane. It is really weird to introduce it, though, when they’re trying to emphasize the power of the Palpatine bloodline. The “All the Sith” thing really deemphasizes the importance of Sheev Palpatine, the man. So why is Rey being Palpatine’s granddaughter that big of a deal? It would almost be better to cut all of that out, and imply it really is just Palpatine, and he somehow found a way to really cheat death. You can’t really change the fact they just call him Palpatine the whole movie.
