How did Rey put the Skywalker lightsaber together? wasn't it lost in ESB? How did they find it? I hate that questions like that aren't even answered.
-Palpatine is back but not how you'd expect. A copy of his consciousness is held within an item (the MacGuffin). He possessed a body and ruled as Snoke. When Snoke was cut in half, his consciousness returned to the MacGuffin.
THE FINAL FIGHT
- Kylo and Rey team up to destroy Palpatine once and for all. (Old 4chan leak, unconfirmed but likely).
Rumor: Matt Smith isn’t Palpatine reborn or rejuvenated but a dark side acolyte, he is willfully possessed by the spirit of Emperor Palpatine. (MSW article)
- Matt Smith’s character (a Knight of Ren) is already possessed when they return to Kylo and eventually turns on him. (Old 4chan leak).
- Rumor: Eventually Kylo Ren kills Palpatine’s host body, then Palpatine’s spirit then jumps into Kylo Ren’s body. Kylo Ren is strong enough to not lose total control of his mental faculties. He struggles to take control of his body but subdues himself and his weapon while beckoning Rey to kill him. Kylo does the right thing and becomes Ben Solo again as he sacrifices himself to kill Palpatine. (MSW article)
-Kylo Ren/Ben Solo is injured at the end of the movie (lots of red makeup used, as well as fake blood). (Source)
-According to Jason Ward, Kylo “kind of dies”, but not permanently, apparently. (MSW podcast)
-The movie supposedly ends on Tatooine (Personal speculation: Probably at the Lars homestead with a Binary Sunset shot). (MSW podcast)
