She returned four years later in series twelve for the wedding of Charlie Fairhead and Barbara Wilder, along with Megan Roach and Martin Ashford. She confided in Charlie that her marriage to Andrew was crumbling. However when she returned in season 14, she had an affair with Max although she and Andrew were still together and remained together until his death at the end of Series 15, which was a hard time for her. She found out that her husband was returning to work at her work place and they didn't get on very well which resulted in another unexpected pregnancy, which Andrew didn't take kindly to and at 5 months she suffered a miscarriage scare which made Andrew realise that he did want the baby. They made up but he was murdered soon after. She later became engaged to security guard and con artist Ryan who disappeared with her life savings. He returned, reimbursed the money in full, declared his love for Duffy and the two disappeared to forge a new life in New Zealand.
