While there are dozens of new questions posed about our beloved galaxy in The Force Awakens, the "white whale" is who is Rey's family? If you're reading this, you've probably already seen the movie, so I won't make a case for why this is so important -- just that we all know how key parentage is to the whole saga. It's the theme of lineage and the passage of the godly force that elevates this series to modern mythology...
I left the theater after my first (and even second) viewing entirely convinced that Rey is Luke Skywalker's daughter. Duh. All signs point to this (the inheritance of the lightsaber, Maz Kanata's cryptic insights, the final scene with Luke, etc). After all, the whole story is about the sins and redemptions of the Skywalker family, right?
"This is not the plot twist you're looking for."
Not so fast. After days of marinating, I'm convinced: that was all misdirection -- too narratively easy for what should be the biggest reveal in this new trilogy. In the following post, I'll make a reasoned case that Rey is in fact Obi Wan Kenobi's granddaughter -- both because of clues planted in The Force Awakens and especially because it would bring the nine episode series to a much more satisfying emotional conclusion; lending more poignance to the earlier films, including the maligned Prequels.
First, the clues:
The accent
The only two "good guys" in the entire series who have British accents are Obi Wan and Rey (if you exclude C3PO). This likely isn't an accident since other British actors (i.e. John Boyega, Liam Neeson) perform with American accents.
The Jedi mind trick scene
The scene in which Rey persuades her Stormtrooper (007) captor to open her cell door and drop his weapon strongly echoes Obi Wan's successful uses of the Jedi mind trick in both the OT and Prequels -- one of his signature abilities. This is not the plot twist you're looking for.
Poking around Starkiller Base
The scenes of Rey scaling the walls and tip-toeing around the First Order's Starkiller HQ echo Obi Wan in A New Hope sneaking around the Death Star and disabling the tractor beam. A superficial homage to Episode IV or a breadcrumb leading to answers about the Third Trilogy's protagonist?
"Ben Solo"
The only reference to Obi Wan in The Force Awakens comes with the reveal of Kylo Ren's real name: Ben. That climactic moment serves to highlight two key things: 1) a reminder of the overall importance of "Old Ben" Kenobi to the broader Star Wars story, and 2) the notable absence of any references to Obi Wan up until that moment -- the only major A New Hope character not to get a prior visual cameo or major plot point (so we think). This omission looks like a filmmaker's "sleight-of-hand," guiding us away from a reveal about Obi Wan later in the new trilogy.
But the clues continue to pile up, addressedhere.
Similar costumes between Rey and Obi Wan (in the Prequels).
Both Ewan McGregor's and Alec Guinness's voices appear in the key basement lightsaber flashback scene at Maz's.
And, lastly, JJ Abrams has suggested that Rey's loneliness is a key to her origin, likely a referencing Obi Wan's status as a lonely hermit between Episodes 3 and 4. Unless Rey is Yoda's granddaughter but probably not.
Sure, these are all basic clues that could easily be discounted, but there's ample fodder with which to rack your brain...
"How satisfying would that be to learn that the nine episode arc is really, underneath it all, about the Kenobi family and not the Skywalkers?"
The deeper strain of this "Rey Kenobi theory," however, is rooted in the concept that Star Wars has always had a certain narrative symmetry: good versus evil, light versus dark, small versus big, faith versus technology. Characters even refer to bringing "balance to the force." These patterns abound in the Star Wars universe, appearing again and again in both minor and major ways. Many have even been critical of how closely The Force Awakens mirrors earlier narrative patterns and beats. That criticism is fair, but it's being used for intentional effect to both guide and misguide and play with our assumptions and expectations.
With that said, here are the juicier reasons why Rey being Obi Wan's granddaughter would ring true and be so satisfying to the completion of the story:
