You're a woman with a 5-year-old son, living in Gotham City. You were Joker's wife until you ran away because you were pregnant and he was a psychopath who didn't care about you or the baby. Only thing he cared about was killing Batman. One day, you come home from work and saw him snuggling your sleeping son. He had a terrifying smile on his face as he was staring at you. You screamed "n-no..." but Joker grabbed you by the neck and slammed you on the couch. He whispered in your ear "I miss you so much, my love."
