Having killed Cathy and passed it off as suicide Sam discovers the truth about his father and, on Christmas Day, confronts Jenny, storming out after refusing to accept her reasons for lying. He joins Chrissy, who has just witnessed her grandmother Margaret abuse her dead mother's name, and they escape to the seaside, where Sam gives her a crucifix stolen from Cathy. Jenny eventually gives in to Sam's demands to see his father, Peter, in prison. Peter appears to be contrite and charming but Jenny fears for her and Sam's future if he is released and she is right to be wary as they plot together out of her earshot.
