If you watched the season two finale of "Gotham" when it aired back in May, you might have heard a familiar laugh during a scene when Indian Hill's patients escaped into the night. If you thought that laugh sounded a lot like Jerome's, the proto-possible-young-Joker introduced early in season two, then you thought right. Executive producer Ken Woodruff confirmed to TV Guide that the laugh was indeed Jerome's (Cameron Monaghan).

"[The laugh] was really to keep [the Joker] alive, to keep Jerome and that threat of the Joker alive. We wanted to make sure fans don't feel that we're completely done with [the mythology of the Joker] because we are 100 percent, absolutely not," said Woodruff. "[But,] it's not going to be something we delve into right way at the top of the season."

While Jerome won't be in "Gotham" at the top of season three, Woodruff promises that the show will explore more of the Joker mythology in "the mid to second half of" the upcoming season. "['Gotham' is going] to delve back into the mythology of the Joker, and characters that may or may not be the Joker -- but more likely characters that are an amalgamation of what we'll come to know as the Joker," said Woodruff. "We are definitely going to hit it."

"Gotham" returns to Fox for its third season on September 19.
