The detectives question Knopf, who admits to having a gun at his parents' house. However, Holder gets so rude with the mother that she threatens to file a report. Linden asks Holder if he is abusing drugs. At the academy, Kyle must bear a form of initiation from Knopf and his superior, AJ Fielding. At home, Linden finds that her social worker and mother figure, Regi Darnell, has cooked dinner, although Linden planned to cook for her son, Jack. Feeling out of control, Linden argues with Regi. Holder later apologizes to Linden. They question Kyle about an injury his mother once received. He replies he broke her wrist when she wanted to become sexual with him. Rayne breaks up the questioning, and the detectives spot a car matching one that had frequented the Stansbury home and was up the road from it on the night of the murders; the car belongs to Rayne. Kyle keeps finding a map of his home with Xs drawn on it and gun. A note is attached, telling him to "Finish what [he] started." Reddick gathers all the clues that lead him to the lake. Holder calls Linden to also get her there. Red bags containing bodies, and Skinner's car, are being pulled from the lake.
