Gotham producer John Stephens recently took part in an interview with TV Guide, where he gave a very straightforward response when pressed for information on when fans can expect the fan favourite character Harley Quinn to appear on the show.
“We might see [her] in Episode 22″, said Stephens, who then went on to elaborate that her appearance in the show would not be a cameo, and would rather be a “launching point” for the season four narrative.
A possible Harley Quinn appearance was first teased back in August, when Stephens said: “We’ll be seeing a character, perhaps not this season, but in times to come, who can be a forerunner for Harley Quinn, which I think will be really exciting as well.”
Gotham airs on Monday nights on Fox.
