The jokers daughter and batmans
son accidentally fall in love with each other and there parents do everything they can to try and stop this from continuing.or perhaps they might use this to there advantage.
Inbetween crime fighting there's life. Life for Batman and Superman even if their villains don't see that. Batman especially has been dealing with more than he can handle and Clark is tired of seeing his friend so stressed out. So Clark suggests a trip to his parent's farm that Bruce reluctantly agrees to. Bruce knows he'll regret it, but goes anyway. For what reason..he doesn't know.
