Episode 5

Beth confronts Mark and then Becca about their adultery. At Karen's suggestion, Olly writes a national news article about Jack's past. Mark confirms the cell phone is Danny's, but Ellie says Danny also owned a smartphone—which is still missing. Lucy Stevens, Ellie's sister, asks for money in return for information about Danny's murder, but Ellie refuses to give it to her. Olly and Karen have sex. Jack is harassed after his criminal record hits the newspapers, but his hatred of police leads him to decline to help Hardy and Ellie clear his name. Dean tells Chloe how Jack hugged and touched him and other boys in the Sea Brigade, and the Echo prints the allegations. The harassment against Jack worsens. Susan makes contact with Ellie's son, Tom, and Mark becomes aware of Chloe's relationship with Dean and confronts her about it. Nigel attempts to bribe Susan to leave town, but she declines the money. A mob attacks Jack at the Sea Brigade hall. Mark stops them and confronts Jack, who reveals he had an affair with a 15-year-old girl, for which he was imprisoned. They married when he was released from jail, and had a son. The son died at the age of six in an automobile accident caused by Jack's wife, and the couple divorced. Mark advises Jack to leave Broadchurch for his own protection. Olly reports that his family's boat is missing, and Beth and Mark begin to reconcile. Jack's car is vandalised, and news of his past makes the national papers. Jack commits suicide by jumping off the same cliff where Danny's body was found.
