Harley Quinn is getting back in the saddle for Season 2 of her DC Universe animated show, and this time she has an itch for her best friend, Poison Ivy.

The first season of the R-rated Harley Quinn saw the title character, voiced by Big Bang Theory's Kaley Cuoco, extracting herself from a shitty relationship with the Joker (Alan Tudyk) and climbing the ranks of Gotham City's criminal underbelly. The creative team behind the show wanted to make sure she was a sister doing it for herself right out the gate.

"What would that say about the character if the first story that we tell is about her being in a relationship with somebody else?" showrunner Patrick Schumacker told Metro UK.

According to Schumacker and fellow showrunner Justin Halpern, Season 1 was always meant to be about Harley's self-care, with intentions to flesh out her relationship with Ivy (Lake Bell) later on in the series.

"We had written all 26 episodes already. We were removed from that glass house, I guess, with people looking at us as we’re doing it," Schumacker told Entertainment Weekly. "Just like we wanted to start with Harley as a criminal and then maybe over a long period of time start exploring some of the antihero stuff that’s in the comics now, we wanted to really slow-drip the evolution of Harley’s relationship with Ivy."

"Breakups come in stages," Halpern added. "We had the luxury of being able to explore what a bad breakup looks like. In Season 2 we were really able to explore, What is it like when you realize you have feelings for your best friend?"

Harley and Ivy being more than just friends has been canon since Harley was introduced in the seminal Batman: The Animated Series in 1992. All the Harley/Poison Ivy (and occasionally Catwoman) episodes were always the most fun and, not coincidentally, the queerest.

Their relationship developed over time in the comics, and they went from being partners in crime to partners in life in 2015, when writers of the Harley Quinn series confirmed that Harley and Ivy were "girlfriends without the jealousy of monogamy."

As recently as 2016, the diabolical duo had pumped the breaks on their romance. But for those hankering for some Poison Quinn action, Harley Quinn Season 2 is ready to deliver.

"At one point in the comics it was very clear and now we’re not so sure, but we’re very sure in the show," Schumacker says. "You’ll see."
