Star Wars: The Last Jedi - 8 Crazy Fan Theories You Need To See
3. Rey Was Cloned From Luke's Hand
Remember when Vader chopped off Luke's hand during their duel on Bespin? Well, apparently, that one single act created a ripple effect that will culminate in a major reveal this coming December.
Because, as YouTuber Mike Zeroh (along with a friend of his) speculated in a recent video, that hand was used by Emperor Palpatine to create a clone of Luke Skywalker - a clone that will turn out to be Rey.
That's all the insight he offers on the subject and he provides no supporting evidence, but the theory is based around the fact that (from what little we know of it) Luke's relationship with Rey will be very complex.
It sounds silly and it's almost certainly false (can you imagine Palpatine moping around Cloud City, looking for the severed hand? Somebody please turn that concept into a comedy short), but if it does turn out to be true, at least we'd all be completely taken by surprise.
