As far as crazy villains go, Barbara Kean (Erin Richards) and Tabitha Galavan (Jessica Lucas) of “Gotham” really take the cake. The two are already wild and wicked on their own, but together, they form quite a formidable duo.

For the next few episodes of “Gotham” Season 3, Babs and Tabs, as they are known, will have a meatier storyline. Ed Nygma (Cory Michael Smith) is out for revenge since he believes Butch Gilzean (Drew Powell) was responsible for Isabella’s death (when in truth, his boss Penguin has his hands all over it).

Tabitha’s kidnapping was featured in the new Grindhouse trailer for “The Sirens.” In it, Nygma threatens to chop off Tabitha’s hands while Barbara wreaks havoc looking for her. But will she save Tabitha on time?

The next episode is titled “Mad City: Time Bomb.” The synopsis, which was shared by Comic Book, reads: “On the eve of their rehearsal dinner, a threat to Mario (guest star James Carpinello) and Lee (Morena Baccarin) is exposed, and Falcone (guest star John Doman) looks to Jim for help. Meanwhile, Nygma seeks revenge and Bruce learns more about The Court of Owls.”

Meanwhile, Ben McKenzie, the actor who plays Jim Gordon, was earlier asked if his character could still repair his relationship with Barbara. After all, the two shared a loving relationship at one point in their lives and were even set to get married.

But McKenzie told Blastr that it’s no longer possible. “I don’t think the relationship can be healed; I do think there’s a chance of personal redemption for all of these characters no matter how villainous they become,” he said.

But what McKenzie loves about the show is that there’s always a way for audiences to empathize with the villains. “I think we really play with the thin line between heroes and villainy on a show like this. Were it not for Oswald (Robin Lord Taylor) being beaten down by Fish Mooney (Jada Pinkett Smith) all the time, maybe he wouldn’t have become the cold-blooded killer he became,” he said.
