When teenager Andy Kralic is found dead on the subway tracks, officers initially assume that he was murdered before surveillance videos show that Kralic walked in front of the tracks himself. Barrow is put in a hard place by Dr. Gordon Stiles, from the coroner's office, who is looking to do an inquest into recent deaths and wants answers about Kralic's suicide. Pogue and Oosterhuis question Andy's friends, Patrick Lee and Linda Ferrero, about Andy's life and school and learn that he had recently gotten in trouble at school for an article the three of them had never intended to put in the paper. Castillo, Pogue and Oosterhuis all disagree on Andy's death, with Castillo convinced someone else is to blame, Oosterhuis convinced that something drove him to it, and Pogue convinced that sometimes there is no reason.
