Season 4
With the Court of Owls decimated, the aftermath of the Tetch virus crippling the city, and every (surviving) villain in Gotham's underworld jockeying for power, Jim Gordon and the GCPD have their hands full. What threat does Ra's al Ghul pose, and will Penguin regain his title as the King of Gotham? What new villains are in store for season four, and what does Bruce Wayne's season finale reveal mean for Gotham City — and his ultimate destiny?
