Here are some tidbits from the interwebs:
Plagueis is said to be able to manipulate medichlorians to create life... Anakin was conceived immaculately by the medichlorians. So what is deal with Rey?
It should be noted that Kylo is not Ben’s given name, it is most likely a combination of his family names sKYwalker and soLO.
Finn refers to Kylo Ren as “Ren” and not Kylo which seems to suggest he could be the only remaining member of the group.
according to Palpatine, “Darth Plagueis was a dark lord of the Sith, so powerful and so wise. He could influence the midichlorians to create life. He had such a knowledge of the Dark Side, he could even keep the ones he cared about from dying.” While Plagueis had the ability to cheat death, Palpatine claimed to have killed Plagueis in his sleep
And we also know that Anakin Skywalker’s lightsaber called to her. Maz even makes a point of saying that the lightsaber belonged to Luke Skywalker and his father Anakin Skywalker before him, “and now it’s calling for you.” So that must mean she’s a Skywalker, right?
Is Rey a Kenobi?
There is one more possibility: She could be Obi-wan Kenobi’s granddaughter. I had heard early on that the change from Michael Arndt’s script to the one J.J. Abrams was working on with Lawrence Kasdan was that it changed the story from being just about the Skywalkers to being a story about the Kenobis vs. the Skywalkers. Again, that was just a rumor and a lot of what we heard early on was wrong or evolved into something else. But it is possible.
Consider this: Obi-Wan Kenobi was in possession of that lightsaber for three decades, while Luke Skywalker had it only for a year or so. The lightsaber calling to her might have nothing to do with Luke and Anakin Skywalker. Also, while Rey is having her vision
we hear Obi-wan Kenobi say “Rey, you’ve taken your first steps.” Of course, Yoda is also heard during this sequence, but of course he is one of the highest Jedi masters of all time. So the question is, if Rey is a Skywalker — why did Rey hear Obi-Wan in her vision and not Anakin Skywalker?
Later in the conversation Boyega mentioned he loved the fan theory that Finn is Mace Windu’s grandson and enthused about an encounter he had with
Samuel L. Jackson at a party. Going by race alone, Finn could possibly be a descendant of Mace Windu or Lando Calrissian. But do we really need to make this universe any smaller than it already is? I would rather see Finn try to explore his past and find a new story with new characters and not make this galaxy any smaller and too connected by fate.
