I don’t know if this has already been said, but I would be upset if Luke Skywalker turned out to be Kylo Ren. That would ruin his whole arc in the OT.
That magazine article from months ago, it was either Empire or EW or Vanity Fair, had photos of Adam Driver as Kylo Ren without the mask on.
Are we sure about that? How about Kylo Ren being the son of Luke Skywalker?
