The Detectives bring him in; afraid he'll hurt his 5-year-old sister. JJ seems to be disturbed, mutilating the genital area of his sister's dolls and having behavioral issues at school. He was in a fight and screamed rape, so they believe he's been sexually abused. JJ confesses he was abused in the Treasury Room by his dad's old boss, Billy Tysen (Will Keenan), a toy mogul. The Detectives investigate Tysen and find out he lives in a Sutton Place mansion, which is more along the lines of a kid's paradise. Tysen claims he loves children and would never do a thing to hurt them.
