Time to put a smile on your face, Gotham fans.

Gotham has already debuted a number of the most famous members of Batman’s rogues gallery, from the Penguin to Scarecrow. The villain who can make the Caped Crusader break his one rule, however, has remained elusive, teased by producers in interviews or hinted at by quick easter eggs in the show.

But now, it looks like the Joker is already set to make his debut on the series, if the promo for next week’s episode is any indication.

A preview for next week’s episode, “The Blind Fortune Teller,” promises that the next villain to invade Bruce Wayne’s home is “no joke.” If that tagline wasn’t quite obvious enough, the promo then cuts to a character, Jerome, laughing in true Mark Hamill style.

Cameron Monaghan, Ian on Showtime’s Shameless, portrays Jerome, a character about whom little else is known other than his creepy stare and maniacal cackle. That certainly fits the Joker’s history, as the character’s origins in the comic book have never concretely been outlined—and even when details are revealed about him, their veracity is always up for debate.

Whether Jerome is the actual Joker or yet another twist on the character’s origins, viewers can find out when “The Blind Fortune Teller” debuts on Feb. 16.
