Anyone who's read JL #42 knows that Batman took control of the Mobius chair and learned the truth about the death of his parents and the Joker's real name. But what else does he now know? Does he know that his universe is fiction? That him and his world are just comic books in another dimension? Or that there are different versions of himself and the others out there? And is this something DC should pursue even if they aren't intending to? What will the Mobius chair actually show him and what should it show him?
