Hannah, a religious woman, was active in the Pentecostal Church but lost all tolerance for her fun-loving husband, Tony Carpenter. After they agreed to divorce, their son, Kelvin, moved to the Square to live with his father in February 1985, while their daughter, Cassie, stayed with her mother. Hannah's first appearance in Walford was in June 1985 and throughout the year she would show up occasionally to converse with Tony about issues concerning their children. Hannah constantly looked down on Tony's lifestyle and career, so their meetings were never pleasant.
When Hannah met the smooth talking corporate lawyer, Neville Agard, she him to move into her house. Eventually, Neville bought the house and they announced their intention to wed. However, when she discovered that Neville had a violent temper and had beaten her daughter with a riding whip, she confronted him and after a row resulted in violence she left him and turned up on Tony's doorstep at number 3 Albert Square in April 1986. Tony was furious and went to confront Neville, returning later covered in blood. Hannah was adamant that she would not return to Neville, so she and Cassie came to live with Tony and they decided to try and give their marriage another go.
Their reconciliation was not a happy one and it wasn't long before Hannah had returned to her nagging ways. She was unhappy to be living in a house that was in the throes of renovation and she constantly harangued Tony to do better and try harder. She also managed to upset her children by trying to put a stop to her son's relationship with Carmel Roberts and forcing Cassie to go to boarding school.
In 1987 Hannah began to become disallusioned with Walford after getting accosted by both Rezaul Gabir and Mehmet Osman. She was also stalked one night by a man known as the Walford attacker, who was guilty of assaulting several female inhabitants of the Square. Hannah was shaken but unharmed. She later relayed to Tony that she feared that Mehmet was the culprit, because he had made a pass at her previously. Tony was furious, and he along with Den Watts and Pete Beale went to track Mehmet down and teach him a lesson. After Hannah discovered that her husband was guilty of attacking Mehmet, she took the moral high-ground and denounced his barbaric actions (Despite previously being happy for Tony to resort to violence against Neville). Hannah then decided that their marriage was over and so she left Walford in February that year to go and live with her sister in another part of London . She was not seen again.
