As he talks with Bruce he mentions how he and Harley talking about how Bruce acted at Wayne Tech allowed him to have a conversation with Harley without him getting her to lose interest in it.

Fanon
Jarley is one of the most popular ships in the fandom (and not only in the fandom) and one of the most shipped. People love the dynamic of their relationship, because of it being ambiguous, extensive and interesting. The fact that the two are villains only makes the fandom ship them more. Jarley shippers often get into fights with Harlivy shippers - usually the main thread is Joker being abusive to Harley in most of the universes. Some of the Jarley shippers also base their DC knowledge mainly on movies and Batman TAS and don't know that Harley and Ivy got together in the comics, which often only goads the quarrels. Jarley tends to be more liked in the continuities where Joker and Harley's relationship isn't abusive, such as The Batman (2004) animated series, Batman: The Telltale Series, the Lego DC video games and The Lego Batman Movie.

Despite most of the Jarley and Harlivy shippers, not agreeing with each other, there are also some people who enjoy both pairings or prefer one of these more, yet still respect/like the other one.

The Harley Quinn (2019) cartoon also was one of the causes in some of the Harlivy shippers change in their opinion about Jarley, because of Joker actually wanting to help in Harley and Ivy's relationship in the last episodes of the 2nd season and trying to convince her to fight for Ivy's love.

However, Harlivy is not the only main rival ship to Jarley as lately Joker got a new girlfriend - Punchline - which was warmly received by many DC fans and quite a lot of people like the Joker x Punchline pairing already.
