I read a theory on tumblr that apple-eating Doctor is a ganger doctor. They mentioned that he also solves a rubik's cube in The God Complex, something he had unable to do in an earlier episode. They also pointed out that the "You've redecorated! I don't like it!" bit in Closing Time is a call back to the Second Doctor, and that they've previously shown Ganger doctor quoting Old Who, so it could be a hint.
But yeah, I"m basically awaiting Saturday, ready to be moffucked.
