Kate soon establishes a business partnership with Den's wife Chrissie (Tracy-Ann Oberman), as she turns out to be a professional hairdresser as well. Kate and Den begin an affair, and when Chrissie finds out, she ransacks the salon and smashes the mirrors. Chrissie offers to cut Kate's hair, and Kate agrees despite earlier insisting that she is too busy. With the reason that the mirrors are smashed explained, Chrissie asks awkward questions about Kate's 'mystery man' with Kate unaware that Chrissie knows about her and Den. Chrissie questions Kate about her lover and cuts her long hair off, leaving most of it short at the nape of her neck. Chrissie attacks Kate and smashes a window before telling Kate's family about the affair and leaving Walford for a few months. Kate has her hair restyled and continues to work at the salon. Chrissie returns and also continues to work there until her investment can be paid back. Eventually, Kate and Chrissie become friends again. Later on, Kate is offered her job in the police back; she takes it and closes the salon before leaving Walford to start anew in Brighton.
