'Gotham' Star Confirms Harley Quinn in Season 3 Finale

It seems Gotham is about to get a spoonful of puddin’. The actor behind young Bruce Wayne, David Mazouz, has confirmed that Harley Quinn, Gotham’s Clown Princess of Crime and fan-favorite accomplice to the Joker, will make her debut in the show’s upcoming Season 3 finale.

In an interview with Movie Pilot, Mazouz said that his young Bruce Wayne will endure “something major” in the very last moments of Season 3, which airs its finale on Monday, June 5, on Fox. Mazouz isn’t clued in to what’s going to go down in Season 4 yet — he says he hasn’t received scripts or spoken to the writers — but he says he sees it going “somewhere I’ve wanted to see it going for a very long time.”

He then added, “Bruce is going to be very busy taking on this new role that he assumes at the end of Season 3 and I think it’ll be really cool.”

Mazouz wouldn’t confirm if Jerome, who fans are, like, 98.7 percent sure is, in fact, the Joker, will come back. But, when it comes to Harley Quinn, Mazouz put it plainly: “She’s going to be in the finale. Stay tuned.” Well then!

Since the show’s second season, fans have theorized that the now-evil Barbara Kean (Erin Richards) will become Harley Quinn, despite the fact she’s not a criminal psychologist named Harleen Quinzel. She’s also a few years older than Joker/Jerome, whereas in other media like comics and movies (e.g. Suicide Squad), Harley Quinn is much younger. But Fox’s Gotham — a non-canonical prequel series to the Batman mythos — has been liberal with the established mythology.

Gotham airs its Season 3 finale on June 5, on Fox, at 8 p.m. Eastern.
