Ray is Palpantines granddaughter and Luke refuses to train her because he senses the evil in her. Kyle Ren can't kill his mom, gets pushed out of the dark side, comes back to take on Rey as the last Jedi in the last one.
WRITE IT DOWN
This makes a lot of sense. I don't see them going back to the "kill your parents" well. I don't see KR offing his mom too.
Have you guys heard this theory that Snoke is like a force vampire sucking the life out of Jedi / Sith to get force juice and heal his broken ***(he appears to be healing over time). Makes some sense in the context of how they'll deal with Leia's exit from the series. Also, maybe they figure out Snoke is some sort of darkside / lightside puppeteer cultivating force users that he can then...feed on. So Kylo (Ben) and Rey bury the hatchet errr light sabre to fight Snoke.
What I saw also couched it in terms of setting up the Old Republic series which Disney will cash in on once Stars Wars ends.
As far as fan fic BS goes it seems kind of legit.
