The cast and crew of “Gotham” assembled for a panel at WonderCon and with just four episodes left in their first season, they offered some teases for the upcoming second season which will air this fall.

Producer John Stephens revealed two potential storylines for the second would including the “emergence of character billionaire Bruce Wayne” as well as an exploration of the character “Jerome,” who was previously teased as a potential candidate for becoming The Joker. In addition, Stephens revealed that two more villains will appear in season two – Clayface and The Mad Hatter.

Variety‘s Laura Prudom was also on hand at the panel and reported they mentioned that the previously-teased Victor Fries, AKA Mr. Freeze, would appear in season two and that they’ve “come close” to doing the fan-favorite Court of Owls but “haven’t yet committed.”

“Gotham” is an origin story of the great DC Comics super villains and vigilantes, revealing an entirely new chapter that has never been told. From executive producer/writer Bruno Heller (“The Mentalist,” “Rome”), “Gotham” follows one cop’s rise through a dangerously corrupt city teetering on the edge of evil and chronicles the birth of one of the most popular super heroes of our time. The series stars Ben McKenzie, Donal Logue, Jada Pinkett Smith, Sean Pertwee, Robin Lord Taylor, Erin Richards, David Mazouz, Camren Bicondova, Zabryna Guevara, Cory Michael Smith, Victoria Cartagena, Andrew Stewart Jones, and John Doman.
