Kat returns to Walford in September 2010, fleeing from a man she and Alfie conned for money. Alfie arrives but Kat is displeased to see him. She reveals to her family that while Alfie was serving time in prison, she had an affair with another man, who proves to be Alfie's cousin Michael Moon (Steve John Shepherd) and is now pregnant with Michael's child. In an attempt to prove himself responsible, Alfie leases The Queen Victoria public house. He struggles to raise the rent, and enters into a partnership with Michael, unaware that Michael is the father of Kat's baby. After an argument with Alfie, Kat agrees to move to Spain with Michael, but ultimately changes her mind and reconciles with her husband.
