Batman: The Telltale Series: Joker Speculation

In episode four: Guardian of Gotham, Joker says to Bruce, "There's something darker in you...I know who you really are." Using these quotes, I think it is very likely Joker is indicating that he knows that Bruce Wayne is none other than Batman. We could see this pay off in perhaps a season two, which I will be speculating the possibility of in a later post today.
