3559 - It's official we're seeing John Fox in the TV show in season 4. ITS A JOKE! But it would be cool for Jonh Fox aka the flash of the future to appear on the show. But the thing with his timeline it's based on Wally West and the shown is mainly around Barry Allen. So it isn't likely Yet. #furture
