When Das returns, Daz invites him and his friend Debbie Dingle (Charley Webb) to move in – needing the rent money. Debbie is attracted to Andy and loses her virginity to him. They start dating secretly, but then her family learn about this and Andy is confronted by Debbie's father Cain (Jeff Hordley) about the revelation. He later ends the relationship with Debbie after Cain threatens to lead Daz into criminal activities unless Andy leaves Debbie alone. Andy briefly dates Libby Charles (Ty Glaser) afterwards, but then discovers that Debbie has given birth to his baby – Sarah. He and Debbie soon break up, agreeing to keep in contact, but Debbie's decision to give Sarah to Emily Kirk (Kate McGregor) upsets Andy. Things get worse when Katie discover that Andy is Sarah's father. When she is involved in a car accident, Andy breaks up with Debbie to get back with her. They soon resume their relationship, annoying the Sugdens, but Andy later has an affair with Kate's new friend Jo Stiles (Roxanne Pallett). When he realises that he is using Jo to get revenge for Katie and Robert's affair, she manipulates him into continuing the affair. Emily returns Sarah to Andy; when Debbie finds out, she gives Andy custody.
