Arrival
Kat Moon in 2000 hasn't she Changed.

My Daughter
When Kat’s ‘sister‘, Zoe, planned to leave London to work with their uncle, Harry Slater, in Spain, she shouted down Kat’s objections with ‘You can’t tell me what to do, you ain’t my mother.’, to which Kat replied ‘Yes, I am.‘ The story was revealed that Harry had sexually abused her, getting her pregnant at the age of thirteen. Her father Charlie Slater, Harry’s brother, was unaware of this, assuming that the father was a boy with whom Kat attended school. He and his late wife Viv raised Zoe as their daughter.

The woman Zoe had called her mother was really her grandmother, her ‘dad’ was really her uncle and her grandfather; her 'grandmother' was really her great-grandmother; her ‘sister’ was really her mother, her three other 'sisters' were really her aunts and her cousins, and her ‘uncle’ was really her great-uncle and her father! Zoe fled Albert Square, and Kat slashed her wrists in despair. Charlie attacked and disowned Harry, and ordered him to leave Albert Square and never return.

One of Kat’s boyfriends was Dr. Anthony Trueman. He was mesmerised by her, and they had a lot of fun, but Kat ditched him when he told her he was falling in love with her. Her daughter, Zoe, later became engaged to Anthony, much to the disapproval of Kat and the rest of the Slater family. Zoe cut all ties with Kat over this. As the wedding approached, Zoe disappeared saying, when she reappeare



d, that she had needed to get away and think about the serious step she was about to take. She was devastated to find Anthony and Kat were back together, this time in a more serious relationship. Kat realised Anthony’s doctor and ‘posh’ friends looked down on her, and that she and Anthony would never fit together, and they broke up. Kat later discovered she was pregnant with Anthony’s baby. She thought about having an abortion but decided to keep the baby. Unfortunately, she had a miscarriage and was comforted by Alfie Moon.It was very sad for her!
