Harley Quinn and Poison Ivy (Harley Quinn)
Years of will-they-or-won’t-they paid off in the Season 2 finale of Harley Quinn when Poison Ivy fled her wedding to Kite Man… and kissed Harley, her would-be wedding officiant. The two characters had long been believed to be bisexual, and to have a thing for one another, and the episode confirmed it.
