Fan Casting Paul Valeska in Batman: Deathtrap

While reading about Harley Quinn's recent escape from Arkham Asylum, he catches the name ''Jerome Valeska'' in the papers, and we see a flashback to Bruce's school years only a few months before his parents were murdered. He and Jerome were in the same class together, and the two had taken their fathers with them to meet their teacher at the time, Mr. McGinnis. He thought very highly of both children, and always greeted Bruce with a warm welcome decades later, not knowing who Bruce transformed into after the deaths of his parents.
