The Force is strong with Rey. We saw that in Star Wars: The Force Awakens. That's why she had to go see Luke Skywalker at the end.
Oops. Hope that was not a spoiler for you... If so, hurry up and catch-up. We have a whole 'nother Star Wars coming in December! Watch the trailer for "The Last Jedi" (the last chapter for the Jedi??)
This teaser has gotta have viewers thinking, "This is gonna be crazy. Good and crazy!" Watch and figure out your own feelings about it though (above).
