He hires Delores Filmore Louise Stebbins, also known as Mortis: Goddess of the Forgotten Dead, a woman with mysterious powers that allow her to seemingly show anyone she touches their deepest regrets and shame. Her touch has been shown to be so powerful that they cause the person to commit suicide rather then face their inner self. Calculator asks her to demonstrate her gift so she takes the hand of Calculator's associate and all of a sudden, the man breaks into tears as well as a cold sweat and then he charges out of a glass window thus falling to his death.
