I don’t really want to change this about the original. My understanding from TROS is that Snoke was a meat puppet, possibly literally housing Palpatine’s spirit before he went into a clone body sometime between TLJ and TROS. One thing about this that gives me pause is that Snoke seemed to recognize that Rey and Ben are linked. But I guess them being a dyad is some weird technicality aside from this.
So… essentially Palpatine is now like Lord Voldemort from Harry Potter, where he transferred his spirit into different bodies to keep himself alive or to perform an action that he could not at the current state?
