Why do you guys keep missing the point, regarding Palpatine’s plans in the film?
He wanted Rey to kill him at first, but her parents hid her away and now he doesn’t know where she is, so he decides to groom the descendant of the Skywalkers instead; he decides to have Kylo Ren kill Rey, believing she is no longer of any use to him. When Kylo Ren fails to kill Rey and turns to the light, Palpatine changes his mind and falls back to his original plan to have Rey kill him.
Regarding the dyad, there’s one idea I had to help remove it to preserve Snoke bridging Rey and Kylo’s minds, trim Palpatine’s line to just “The life force of your bond… restores the one true Emperor.”
