Anthony and Kat's relationship resumes, but she fails to impress his colleagues and breaks up with him as he is about to propose. Kat discovers she is pregnant by him and decides to have an abortion. Her boss Alfie Moon (Shane Richie) persuades her not to, but she suffers a miscarriage shortly after telling Anthony of the pregnancy. Alfie comforts her and realises that he is in love with her. Kat soon begins a relationship with local crime kingpin Andy Hunter (Michael Higgs), and they end up getting engaged. However, Kat confesses to Alfie's grandmother Nana (Hilda Braid) that she loves Alfie – who upon discovering this intervenes; he stops Kat and Andy's wedding and confesses his love for her. Kat leaves Andy, and she and Alfie marry on Christmas Day. Alfie later borrows money from Andy which he is unable to repay, so Andy threatens to kill him unless Kat has sex with him. A reluctant Kat does so, but unbeknownst to her Andy films the liaison and sends it to Alfie. Alfie becomes cold and distant and Kat resorts to alcoholism. After a one-night stand with a stranger, Roger (Russell Boulter), a disgusted Kat leaves Walford.
