The question on Leia would be, why would her children be living like they supposedly are if she's part of the government? If we assume that Ray is a Solo/Skywalker/Organa, why is she a junk dealer? That reasoning is probably why the rumor mill is proposing that Leia is dead by the "present" and died not long after Return of the Jedi. That might also account for Luke going into isolation and Han being someplace else. Though we are presented with very little in terms of the older heroes at this point. Are Han and Chewie just coming back to the Falcon for the first time in years? Why? If Ray is his and Leia's daughter, why is she out here dealing in junk? Why is Luke seemingly not doing what Yoda requested on his deathbed...pass on what he had learned?
It has been 30 years since Endor. What is going on? Well the new story materals will start to come out around September and go into December when the film comes out.
