This Star Wars Theory Breaks Down Why Obi-Wan Kenobi May Be Rey's Grandfather

In episodes three and four, the films end with dramatic lightsaber duels between Obi-Wan and Anakin Skywalker (and eventually, Darth Vader). If Rey is definitely a Skywalker, the epic duel she has with Kylo Ren at the conclusion of episode seven would be crazy enough (since that would mean they're cousins or siblings). If we retrospectively discover she's a Kenobi, however, their duel would hold more significance given the two are basically reviving the battle their grandfathers once fought.
