S1·E19 The Agony and the Ecstasy

Just as Mannion and his ex-wife, Sherry, are making plans to get back together, their son, Jack Jr., arrives for a visit. He brings his new girlfriend with him and they announce they're taking a year off college to travel through Europe. The problems grow bigger when Jack Jr. is confronted by his dad for using ecstasy and is later arrested at a rave party for possession and traffic. Meanwhile, a kidnapped woman calls from a car's trunk begging for help before she is killed; Nick has to face neighborhood problems at his new house and Parras is confronted and suspended by her superiors after her gun is stolen by a man she picked up at a bar and used to kill a man.
