Rey is Obi-Wan’s Granddaughter
Rey’s origin is subject to countless Internet theories. She’s Darth Vader reincarnated, she was the result of a virgin birth just like Anakin, she hatched from an egg (more on that later). It seems highly unlikely that the new “Star Wars” flicks would retread the much maligned immaculate conception plot from the prequels, but the theory that Rey is a Kenobi… that’s not that crazy.
The main argument for this theory is that the episodic “Star Wars” tales have always revolved around one theme: family. And more specifically, it has (for better or worse) always centered around the Skywalker and Kenobi dynamic. Obi-Wan raises Anakin, trains Anakin, is betrayed by Anakin and ultimately is killed by Anakin all while becoming a sort of father figure to Luke. That theme would be easy to continue if Rey and Kylo Ren continue to clash, as Kenobis and Skywalkers seem destined to do.
And yes, we are implying that Old Ben took up with a lover in the sand dunes of Tatooine, Jedi code or not he’s only human.
