The episode concludes with an example episode about the Rosetta Stone, demonstrating how a seemingly dull bureaucratic artifact became key to unlocking Egyptian hieroglyphics.

Summary Preview
This episode examines the history of missing children on milk cartons, beginning with the 1982 disappearance of 12-year-old Iowa paperboy Johnny Gosch. The campaign, which started locally and went national, printed billions of cartons but found only two children alive. The story explores how this campaign shaped American fears around child safety, the racial disparities in which cases received attention, and how stranger danger mythology persists today despite most abuse coming from people children know. Through stories like Bonnie Bullock—who found herself on a milk carton—and modern conspiracies like Pizzagate, the episode reveals how we prefer comforting fantasies about external threats over confronting systemic realities of child abuse.
