You were at Penguin’s party that he was throwing for his nephew’s bar mitzvah and you noticed Harley had shown for the first time since she broke things off with the Joker and she looked different. You decided to call Joker. He was about to shoot someone but stopped once he saw you calling. He rolled his eyes and picked up. Joker: knock knock, who’s there? It’s me Joker. he says in an uninterested and dry tone of voice.
