Another thing I noticed: Kylo says “we’ll kill him and take the throne” to Rey (hangar), but doesn’t he already know, in this version, that killing him means spirit transfer?
Maybe that’s why he needs Rey’s help to kill him, rather than killing Palpy by himself immediately in the opening? Like, together, they’ll be able to prevent the spirit transfer? I think that actually makes more sense than the theatrical “I’ll leave Palpatine alive for no reason whatsoever.” I think it’ll be fine as is.
