In 2015, Kat reveals that Zoe has moved to Spain and announces to Mo that she will start saving up to visit Zoe. However, Mo tells Stacey that Zoe does not want to see Kat. Mo attempts to contact Zoe to get her to reconsider, but Kat finds out two days later in a text from Zoe that she cannot see her because of her new job and boyfriend and she feels she needs to move on with her life without Kat. In May 2015, Kat visits the convent where she gave birth to Zoe in 1984 and it is revealed to the viewers that Kat had in fact had twins – meaning Zoe has a twin brother. Kat later moves to Spain and visits Zoe, who rejects her mother, leaving Kat devastated. Kat also reveals that Zoe is now engaged.
