We just saw confirmation of the rumor that Harley Quinn will be in the two-hour season 3 finale of Gotham next week, and now a featurette reveals another villain we’ll see before season 4. Bruce will finally meet Ra’s Al Ghul, played by Alexander Siddig from Game Of Thrones.
Bruce Wayne actor David Mazouz recently said “Something major happens in the very last scene of Season 3 for Bruce.” He also referred to a “new role that he assumes” at the end of the episode. Ra’s Al Ghul may well be influencing that decision, based on how Alexander Siddig described his approach to playing Al Ghul: “I want him to be mysterious. I want him to be ambiguous. I want him to be incredibly cruel at times and then kind and paternal at other times. […] I can get Bruce to cross a line that he should never cross.”
Fox also released a clip from and synopsis for the season finale:
With the deadly virus spreading throughout the city, the search for the antidote continues, as Fish Mooney (guest star Jada Pinkett Smith), The Riddler and Penguin reveal plans of their own. Bruce meets Ra’s Al Ghul (guest star Alexander Siddig) and completes his last task in order to fulfill his destiny, but realizes he can’t let go of his past. Meanwhile, Gordon tries to win back Lee, and past alliances within Gotham City are broken, while new alliances are formed in the all-new, special two-hour “Heroes Rise: Destiny Calling / Heroes Rise: Heavydirtysoul” season finale episode of GOTHAM airing Monday, June 5 (8:00-10:00 PM ET/PT) on FOX.
