1. She sounds like a Kenobi, accent-wise.
Rey and Obi-Wan are the only main characters (besides C-3PO) who have, to our Earth ears, English accents. None of the Skywalkers have that accent — so whoever raised Rey must have had an accent that sounds a lot like Obi-Wan’s.
2. Her Force vision upon touching the Skywalker lightsaber features both young and old Obi-Wan, which took more effort than you think.
A producer for The Force Awakens went back into old files to find a clip of Alec Guinness, the original Obi-Wan, saying the word “afraid” so they could cut the word to say “Rey.” Ewan McGregor came back to voice a single line: “These are your first steps.”
Why would they bring back both Kenobis (one from beyond the grave) to speak in the vision if they had nothing to do with the new trilogy?
3. Rey’s time on Jakku can just as easily mirror Kenobi’s exile as Luke’s.
Some say that Rey’s abandonment on a desert planet like Tatooine echoes Luke Skywalker’s beginnings, but Ben Kenobi lived on that same planet with him for the same amount of time.
4. Rey demonstrates an innate ability for Jedi mind control, which was one of Obi-Wan’s specialties.
Within hours of discovering her Force sensitivity, she mind-controls a Stormtrooper (hilariously played by Daniel Craig) to let her go and drop his weapons.
Many Force users are skilled at mind control, but it is a hallmark of Obi-Wan’s powers specifically, considering that his most iconic line from the original trilogy is the classic “These aren’t the droids you’re looking for.”
5. Rey was able to Force-grab the lightsaber over Kylo Ren, potentially because the lightsaber had switched loyalties.
The lightsaber Rey finds and Force-wrests from the snowbank is Luke Skywalker’s lightsaber, which he inherited from his father, Anakin. HOWEVER, the lightsaber in question is the second lightsaber owner by Anakin Skywalker — his first was destroyed in battle.
Anakin had his second lightsaber for approximately three years, then lost it in battle to Obi-Wan, who held on to it for 19 years before giving it to Luke, who had it for another another three years before losing it in Cloud City. So that’s six years of Skywalkers carrying the lightsaber and NINETEEN YEARS of Obi-Wan carrying it.
Maybe the lightsaber become a Kenobi artifact after so many years with the Force-sensitive Obi-Wan, and that’s why it went to Rey instead of Kylo.
6. It’s unlikely that Luke would break his Jedi vows and father a child after seeing what happened to his father, but Obi-Wan had 19 years of non-Jedi life to get busy.
Luke finding out that Darth Vader is his father and presumably learning the story of how breaking his Jedi vows opened Anakin up to the dark side would HOPEFULLY have had a sobering effect on Luke’s desire to procreate. Since we know he did become a Jedi master, it would make him a hypocrite to do so with a child of his own.
When we meet Obi-Wan, he is an old man living alone in the desert and is extremely secretive about his Jedi past. After Anakin destroyed the Jedi Order, Obi-Wan had no vows to break and could have procreated morally during the 19 years between the prequels and the original trilogy. While this child cannot be Rey because she’s too young, it’s entirely possible that Obi-Wan’s child is one of Rey’s parents.
7. It makes thematic sense for Rey to be a Kenobi, as Star Wars is about bringing true balance to the Force.
Obi-Wan Kenobi raised the fatherless Anakin as his Padawan, and ultimately failed to keep him on the light side. All of Anakin’s failings can be attributed to Obi-Wan’s inability to keep the young Jedi on the right path, meaning many of Darth Vader’s atrocities fall squarely under Obi-Wan’s responsibility.
Anakin went on to father Luke and Leia. Luke abided by the light side as a Jedi under Obi-Wan and Yoda’s tutelage, but Leia’s son Ben Solo was seduced by the dark side like Anakin. We now have two young Jedi: one of Anakin’s blood who is dark, and the mysterious but insofar light-oriented Rey.
If the new trilogy is truly the story of how balance in the Force is finally achieved, it makes sense that this balance must come back by righting the wrongs that led to the overpowering darkness present in the galaxy. The initial wrong, the first domino that fell to create the current imbalance, can be traced directly to Obi-Wan Kenobi. It should fall to a Kenobi to correct it.
8. Maz Kanata heavily implies that Rey’s family is gone and a non-relative will be important in her future.
“Your family is not coming back, but there is one who still could” insinuates that Rey’s family is never coming back, to Jakku or otherwise, but the “one who still could” is very likely Luke, who she meets at the end of the movie.
Luke is the son of a man who was trained by Obi-Wan. He is spiritually Obi-Wan’s grandson. That makes Luke the closest thing Rey has to family if she is Obi-Wan’s granddaughter, but crucially he is NOT related to her.
9. Kylo Ren’s real name alludes to the fact that Star Wars has always been about Jedi fighting their fathers.
The prequel trilogy ended with a massive fight between Anakin Skywalker and Obi-Wan, who functioned as his father figure.
The original trilogy ended with a battle between Luke Skywalker and his father, Anakin, under the Sith name Darth Vader.
Kylo Ren’s real name is Ben Solo, almost surely after Ben Kenobi — which was Obi-Wan’s name while he lived on Tatooine.
Wouldn’t it be poetic if this trilogy ended with Rey fighting against “Ben,” a man who bears her forbear’s name?
