Libby is devastated to learn that a body discovered buried in the Square is that of her father. After speaking to Liz, Libby disowns her as she called the police to say she thought Denise was capableof murdering Owen, and she was taken away for questioning. When Adam brings Libby flowers and says Owen must have been murdered for a reason, Libby shouts at him for patronizing her. Chelsea tells Libby that Lucas found Trina's bracelet in Denise's bag after she died, leading them to believe that Denise may have killed both Trina and Owen. They see Denise driving away from the Square alone, and receive a text message from her saying "I'm sorry". In reality, Lucas had killed Owen and confessed to Denise, taken her to a canal and strangled her, sending the text message before throwing the phone in the canal. Libby is the only person who believes that there is no way Denise could have done this and says that "sorry" could mean anything. However, the police tell the family that Denise's car has been found by the canal, before a body is pulled from the water. Libby vows to carry on as normal, but says that this is not like Denise. The police arrive and say they have found a body in the canal along with Denise's mobile. Libby and Patrick comfort each other while Lucas and Chelsea go to the mortuary, where Lucas identifies the body as Denise.
