One thing kind of stuck out to me in a recent rewatch of Rise of Skywalker. Palpatine is blowing all kinds of smoke up Kylo Ren's ass to kill Rey, when it's all a ruse to lure Rey to Exogol so Palpatine can chide Rey until she gives in and kills him. All well and good. EXCEPT. Why doesn't Palpatine just let Kylo Ren kill him when he's LITERALLY SAYING THAT'S WHAT HE'S GOING TO DO AT THE BEGINNING OF THE MOVIE? You could argue that Palps wanted to inhabit his granddaughter. Palps could also do the same thing after inhabiting Kylo Ren (a descendant of the Skywalker line). So, if the whole piss Rey off thing doesn't pan out, Palpatine still has a younger body of the Skywalker lineage to inhabit.
