((This will also be a story about their children))

The Joker and Harley Quinn were sitting in their nightclub where other people were drinking, filtering, dancing and talking

((Jack and Lucy were their children The Joker and Harley Quinn but Harley and Joker didn't remember them, Jack was 18 and Lucy was only 5))

Jack was in the same nightclub as their parents with his friends and Lucy was with him because he was afraid to leave her alone at home
