Liam skillfully plays an acoustic guitar during The Jockey's talent night in episode 12. By then, he seems to have eventually warmed to Libby after she promised him that she would never leave no matter how much Frank might put her off. In various episodes, Liam is seen to adopt Debbie's mannerisms and views in respect of his feelings about religion, figures of authority and the ways in which his family cope with one another. Debbie was Liam's main care-giver and role model since Fiona's departure from Chatsworth in series 2, being the main nurturing influence in his life from the ages of four to ten. Debbie and Liam had such a strong bond with each other, that she would frequently use his help in various activities. It was to Liam whom she addressed the letter to when she was assigned to Afghanistan.
