The 47th episode of "Batman: The Animated Series" showcases 'Harley and Ivy.' The story depicts the first acquaintance of Harley Quinn and Poison Ivy, who work together and commence on a crime spree. The most popular character for being Joker's girlfriend is found to be in a relationship with a woman as well.
Wow, I mean Harley/Ivy is canon. Through a recent tweet made by writers of Harley Quinn series, Jimmy Palmiotti and Amanda Conner, the confirmation came up. Now it would be great to watch over the two of the closest chums in Gotham city.
