The Joker kicks Harley Quinn out, declaring that his life will be better off without her. And thanks to the Riddler, Joker gets to see if that's true. This story is a belated birthday gift to my #1 fan, blackcat9517, whose support and suggestions have been invaluable :-) Thanks also to TeamRocketRose-Rachel, Starscream's Biglover, AllxThatxRemains, and Unsound Escape for the ideas!
