5) She Is Obi-Wan’s Granddaughter
Then again, there is another character at one with the Force that Rey could be related to. He might not be around anymore, but some have theorized that Rey is actually the grandchild of Obi-Wan Kenobi. After all, he had to do something in all those years he was on Tatooine.
Just like there are parallels between Rey and Luke/Han, there are characteristics that she shares with Kenobi – chiefly, they are both loners who lived on a desert planet. This theory does have an extra obstacle in that you would have to account for the never-before-seen other Kenobi who would be Rey’s parent but, don’t worry, they’ve got this covered, too.
As Benicio Del Toro has been confirmed for Episode VIII in an unclassified role, it could be that he is playing Obi-Wan Jr. (or whatever his name is), Rey’s dad.
Of course, the largest chunk of evidence for this theory is how Rey hears Obi-Wan’s voice when she touches Luke’s lightsaber (in an easily-missed cameo from Ewan McGregor). A lightsaber which, by the way, was also in Kenobi’s hands for two decades, which would explain Rey’s affinity to it. That said, she also hears Yoda’s voice when she touches the saber…
So, Rey is the love child of Obi-Wan and Yoda – a new theory is born!
