As Batman was flying home he saw someone doing cartwheels on the buildings and looked familiar to him so he brought out his binoculars to see. He saw it was Harley Quinn with a bag of stuff so he lands his batplane on a building to confront her.
"Whatcha got there Harley?" Batman asked. "Toys!" Harley said as she unleashed them as bombs and weapons made as toys. Batman then tried to batarang them but only half of them would be destroyed successfully while the others would explode causing both Batman and Harley to fall down the alley.
"Now Batman, are you ready to apologize for killing my father?" Harley asked. "I don't need to apologize for having the man who murdered innocent people dead" Batman answered. Harley then kicks him in the stomach and tries to punch him until Batman catches her fist. He then uses his bat grapple to go up to the building and get back in the batplane to go home. As soon as he makes it to the batplane, Harley attacks him from behind by hitting him in the head.
"Ha ha ha ha ha. Now Batsy…" Harley said until Batman gets up immediately. "No more games Harley. The past is the past and your father is dead. So move on" Batman growled. Harley then punches him in the face and says, "No! I won't give up until you are good and dead! And then the whole world will recognize you as a fatty batty who murders people until they turn into little dimplings!" Harley kicks him in the stomach until she decides to use a slim ball on him. "Oh Batsy, what a little weakling you are" She then uses her knife to stab him in the back and laughs as Batman moans in pain louder. "I know you'll be having a miserable night tonight. See you around" Harley said before she took off. Batman then slowly made his way back to the batplane and went home for the night.
