Don’t get me wrong krausfadr, if I had to pick between “Rey Palpatine” and “I killed your parents”, I would still vote for your idea!

Every alternative to Rey Palpatine is going to have issues, and I think it is worth pointing out what the issues might have to be addressed to get it to possibly work. Like, if Kylo is going to admit he killed her parents, you have to decide why he decides to tell her the truth now, how does her knowing the truth benefit him and his goals. Does Kylo admit it with regret? Does he confess once he realizes Palpatine has been manipulating him all along?

I was originally thinking that a vision of the future could be what drives Rey to want to personally kill Palpatine. Maybe Rey and Kylo both have visions that Rey, and the Resistance, are going to fail. She could have a vision that the Emperor will kill Poe and Finn, her new family. The vision could show flashes of the battle, lightning coming from below. We could use the shot of Snap’s X-Wing crashing to show Poe dying in the vision. Then create a shot of Finn on the Star Destroyer as it explodes in mid-air.

Kylo Ren could tell her, “You will fail, Rey. Your friends will all die. We can only defeat him together. Join me.”

This vision would be what makes Rey want to personally kill Palpatine.

EDIT: I know it’s a joke but mad libs is an accurate description of what we’ll be basically doing to Kylo’s dialogue for this movie. 😂
