Sherlock I completely agree with your assessment in regards to the logic behind it all, but specifically more about the transfer crap for me. Fortunately, I think … it isn’t explained in the movie about “Strike me down with hate and that allows me to transfer” as that is explained outside of the movie (Please correct me if I am wrong). By the movie’s logic, Palpy can transfer … mostly by being struck down by someone (though he somehow transfer from DSII … just don’t think too hard on it.)

Please remind me, but the whole exegol scene with Rey there doesn’t have Palp mention/explaining/talking about the transfer to Rey? If it isn’t mentioned at all at that point, then for Rey’s knowledge and understanding, Palp is saying “You strike me down by this ritual, then you get to have the throne … AKA you kill the boss you take over …” and not “You strike me down by this ritual, I/we/sith will utterly possess you and you get the throne as MeWeSith Lady” then Rey would have a reason to do it … since “I would be the boss, I can call off the destroyers.” That would make sense for her to decide/reason on why to do it, and we the audience are like “oh no, it’s a trap!”

But yeah, regardless, the whole Sith Transfer thing is still goofy but as long as it never touches on the idea of “strike with hatred allows the transfer” in this movie and she doesn’t know it, then it’s at least tolerable. Since Rey is CLEARLY not doing it out of hate at all and why would she do it if she loses herself and palpy takes over?

Keep it somewhat simple.
