Andy visits the home of a teenager, Matt, who accused Leonard Patz of sexually assaulting him. Andy attempts to question Matt but the visit turns confrontational and Matt's defensive behaviour leads Andy to believe he's hiding something. Later, Andy follows Patz to his apartment and takes note of his address. At home, Andy is pleased to find Sarah visiting Jacob; later that night, Jacob tells him that Sarah believes Derek killed Ben and that the police conducted a second interview with Derek. Privately, Jacob creates a secret Instagram account despite his parents' rules banning him from social media. Meanwhile, Laurie is becoming increasingly unstable, spying on her former coworkers and lying to Andy about having dinner with a friend when she actually ate alone at a diner. At the diner, she is approached by a friendly woman whom she confides in; when the woman reveals herself to be a freelance writer working on a story for The Boston Globe's Sunday Magazine, Laurie leaves in a panic without insisting her comments were given off the record and does not tell Andy about the incident. Dr. Vogel conducts multiple tests to determine any psychopathic tendencies in Jacob and takes a DNA sample from Andy. Dr. Vogel reveals that they also need a DNA sample from Andy's father, but that he will only provide a sample if Andy obtains it himself. Andy, despite his anger and fear of his father, agrees.
