I've had some thoughts recently about the subject of Rey's parentage, and how that plays into the story of TLJ and the broader sequel trilogy.
And it has to do with the rift between Han Solo and Leia. I'm beginning to think that Rey may be the child of either Han OR Leia, but not both. In TFA, we don't really get a sense of how long Han and Leia have been seperated. Is it possible that the cause of that rift may have been some sort of infidelity? And that Rey could be a child born from that infidelity? With the Han Solo movie coming this spring (with Emilia Clarke in the cast), I have to wonder... could Emilia Clarke's character be THE OTHER WOMAN in Han Solo's life? Because there's a little bit of a resemblance between Emilia Clarke and Daisy Ridley to the point that it has me wondering. And having both the Falcon AND Rey stranded on Jakku seem a bit... convenient, along with Han and Chewbacca finding the Falcon in the Jakku system.
I'm also wondering if Han may have at least had *SOME* degree of Force sensitivity. Not to the degree of being able to become a Jedi. But his luck and piloting abilities are far beyond those of most people. And that moment in TFA when he shot that First Order Stormtrooper without looking? Yeah, Han is cool. But the ability to do that seems a bit beyond the ability of normal people.
And on the subject of The Force... I've been struggling with one bit of the timeline in TFA. Specifically with the "awakening" that Snoke references when he speaks with Kylo Ren. Was Rey's escape from Jakku aboard the Falcon really an awakening?
And regarding Han Solo? I've also heard some theorizing about his confrontation with his son. As if Han knew how things were going to play out before he walked out onto that gantry on Starkiller base. Did Han realize that Ben needed to be even more powerful in order to confront Snoke? And did he ignite the lightsaber himself? I suspect that the conflict within Kylo Ren is very real. And that he may need to plunge himself further into the Dark Side in order to truly destroy Snoke.
Of course I could be totally wrong. But these are some theories I've been kicking around.
