BRENNAN: To "whom". BOOTH: Because this boy is missing. BRENNAN: Which suggests he was sexually assaulted. BOOTH: And the day that Charlie disappeared - all three boys went to the park? Even from each other. BOOTH: That must've been before you and Charlie went to the park. [On the screen, we see Charlie walk over to a person, who's obscured by a banner.] MARGARET: No. BOOTH: I had to arrest her. They're treated like garbage. [On the Angelator, a pair of legs appears on top of Charlie's horizontal form, and the bones of both people are shown through their bodies.] BRENNAN: Charlie was small and weak. [Brennan pauses for a moment.]

Summary: Brennan, working hard on her latest novel, is enlisted by Booth to help locate and identify the remains of Charlie, a 6-year-old who went missing from a local park. Brennan determines that Charlie was sexually assaulted before he was murdered, which leads Booth to conclude they're on the hunt for a serial pedophile. When the prime suspect is eliminated, Booth and Brennan pay a heartbreaking visit to Charlie's mother, Margaret, to inform her that Charlie's killer is still on the loose. Suspicion creates uncertainty - among even the people closest to Charlie - and Brennan and Booth must investigate all leads, no matter whom the information points to.
