Phil decides to sell The Queen Vic, as revenge for Alfie's treatment of Roxy, and Kat and Alfie move back in with Mo. Kat then reveals that she is pregnant by Alfie, and discovers that she is having twins. Having spotted her cousin Stacey Branning (Lacey Turner) from the top deck of a bus, Kat decides to track her down. She visits Janine in prison, and agrees to provide a false witness statement for Michael's murder, in return for Janine dropping false charges against Stacey, so that she can return to Walford. At her trial, Janine confesses to her crimes, and Kat is charged with perjury. She is devastated when Stacey hands herself over to the police for Archie Mitchell's (Larry Lamb) murder (see Who Killed Archie?), five years previously. Kat attends a hearing, and is given a suspended sentence. After the market is merged with Spring Lane, Kat immediately clashes with her new rival, Donna Yates (Lisa Hammond) and is later surprised when Alfie reveals he has bought a pitch on the market. Kat gives birth to Bert and Ernie Moon. Stacey is released after she appeals her sentence and comes to live with Alfie and Kat. The financial situation becomes worse for the Moons when Alfie reveals they are to be evicted as they have not been paying their bills.
