Stop trying to confuse us, J.J. Abrams. It is absolutely OBVIOUS that Rey is Ben’s granddaughter*; accent, attitude, we desperately need somebody in the Star Wars universe who ISN’T of the Skywalker family to be Force-aware, and so on. I know that Abrams will readily lie to our faces about details of his movies, but he’s playing a double fake-out, here.
Or I just want Rey to be Ben’s granddaughter.
*And yes, the irony would be rich, and succulent.
