Clair discovers a marijuana joint in one of Theo's school books. She and Cliff confront him about it, and accept his explanation—another boy slipped it in. Theo confronts the boy and brings him home to confess in order to remove any uncertainty from his parents about his telling the truth. Theo and the boy actually start to become friends, but Clair starts to think Theo and his friends are part of a drug scheme.
