The DC Comics crime series Gotham is set to return to Fox later this month, and ahead of its spring premiere the cast and producers headed to WonderCon this weekend to promote the series chronicling the young James Gordon and even younger Bruce Wayne in their journeys toward becoming Gotham City’s protectors.

Actors David Mazouz (Bruce Wayne), Camren Bicondova (Selina Kyle), Cory Michael Smith (Edward Nygma), Erin Richards (Barbara Kean), Jessica Lucas (Tabitha Galavan), and Drew Powell (Butch Gilzean) were joined by executive producer Danny Cannon for their spotlight panel, in which they showed a new trailer as well as the first five minutes of the upcoming episode, “How The Riddler Got His Name.”

The series took a hiatus after a huge confrontation between Robin Lord Taylor’s Oswald Cobblepot and Nygma, who came up on top and is poised to make a huge impact on Gotham City as the series approaches its season finale. While speaking about other villains that could debut on screen, alongside the recently announced casting of Alexander Siding as Ra’s Al Ghul, Cannon revealed anyone who is set to appear in a DC Film is off limits.

UP NEXT: Gotham Casts Game of Thrones Alum Alexander Siddig as Ra's al Ghul “If they’re not making a movie about them right then, we’re good,” Cannon said. “But they are making movies.”

Smith spoke about Nygma’s journey toward becoming the Riddler, revealing that they’re going to shy away from the look Jim Carrey employed in Batman Forever. “He’s got some nice threads…I’m not going to be in a onesie, but yeah—theres a costume,” Smith said. “The great difficulty here is that Edward, his opportunity to be a good person and live a normal life is passed,” Smith added, “He knows that his destiny is to wreak havoc. Now is the time.”

Nygma’s own arc will mimic that of Mazouz’s Bruce Wayne, who will be faced with his own trials in the end of the season. “Bruce will go through a major transformation in these last eight episodes of the season, and it will result in him making a decision that he’s been searching for, for a very long time,” Mazouz said. “It will be the most important decision of his life. He is going to live out the reason he was created, and it will have very bad consequences for Bruce—catastrophic consequences. I don’t want to give away too much, but it’s not going to be pretty.” The panel then turned toward Bicondova’s portrayal of Selina Kyle, hinting that she may join up with Barbara and Tabitha in the future.

“I always love that concept of a female-only gang, Cannon said. “I think that’s something we’re really going to explore.” To wrap things up, the panel discussed the presence of the Court of Owls, who have a long history and strong influence in Gotham City. “We’re heading towards, is there somebody else behind the Court of Owls?” Cannon asked rhetorically. “We’re still unraveling what the city of Gotham is, how the city was created, who’s in charge. Things will get a lot worse before they can get better in the city of Gotham.” Gotham returns to FOX Monday, April 24 at 8 p.m. for the final eight episodes of the third season. No official season four pick-up has been announced yet for the series.
