They end up in a physical altercation. Lydia continues to pursue John’s kidnappers. They eventually corner him and the SWAT team kills the suspect when he won't surrender. Lydia's relationship with her former partner, Russell (Tom Everett Scott), grows. Ben's previous girlfriend, the school teacher, continues to bother him; she shows up at Ben's current girlfriend's house that she found by installing a location finder application on his phone. John copes with the aftermath of his kidnapping but doesn't want to admit he's having a difficult time. He's currently on desk duty which he's upset about. It doesn't help him when his ex-wife, who he has been staying with since his kidnapping, tells him she no longer wants to have a child with him. All his stresses come to a head when the neighbors John suspects of growing marijuana call him a pig for turning off their loud generator. John disarms one of the neighbors and uses his gun to beat the other neighbor. The police show up and shoot John twice when he stands up, gun in his hand but at his side. The episode fades out before it is known if John lives or dies.
