The Joker and Harley Quinn go hand in hand, so when Gotham gave Jeremiah Valeska his full Joker story arc, fans were prepared to see some kind of tease that a Harley Quinn type of character was on the way.

Wishes came true when Jeremiah's right-hand-lady Ecco showed up in last week's episode, donning a full clown suit and mask, looking a lot like Harley Quinn. The connection between the characters was taken even further at the end of the episode when Ecco was killing Wayne Industries security guards alongside Jeremiah, wearing a Harley-esque skirt and diamond pattern.

Gotham did a lot to tease Harley Quinn last week, but that doesn't mean she will be a focal point in the story moving forward. In fact, according to star Cameron Monaghan, Ecco won't play much of a role at all in the final two episodes of Season 4.

"For the finale, there's less of a focus on that because we want to make it more specific to the relationship between Jeremiah and Bruce," Monaghan told ComicBook.com in an exclusive interview. "That becomes the primary focus. I think that, fingers crossed, if there's a season 5, that could be something we could explore then, but because there are a lot of moving parts coming together to make the final two episodes. I think that the writers didn't intend for her to come into play. It was really one of those things where there was moving focus and they couldn't. It was a conversation I had and mentioned to them, but I think that ultimately they just didn't want the core story that they were trying to tell be diluted for these last couple episodes. That's something that would work better with a bit more room to play next year."

There is certainly a lot of potential for Ecco to grow into an important character on Gotham, but it sounds like that is all dependent on the show getting renewed for a fifth season. As of now, FOX hasn't yet announced its decision regarding Gotham's future, but its likely the network will reveal the Batman prequel's fate at next week's Upfronts presentation.
