A few years later, Peggy finds herself reacquainted with Archie after getting to know his two daughters Ronnie (Samantha Womack) and Roxy (Rita Simons) respectively. She forms a relationship with him and the pair get engaged, although Archie quickly begins to subtly controlling Peggy. They nonetheless get married, but it ends a few hours later when it is publicly transpires that Archie lied to Ronnie about her infant daughter's death. Peggy has Archie evicted from The Queen Vic and attempts to have Phil kill him in revenge, but she is left furious when Phil lets doesn't go through with it in the end. Peggy files for divorce and Archie plots revenge on the entire Mitchell family. When Peggy loses the bail surety she has paid on behalf of her daughter Sam (who breaks the conditions of her bail following coercion from Archie), the Mitchells are forced to use The Queen Vic to gain a collateral loan from Phil's sworn arch-rival and estranged stepson Ian Beale (Adam Woodyatt). Thereafter Archie uses Janine to blackmail Ian into selling him the loan, and when the Mitchells are unable to meet the loan repayment, Archie evicts them and assumes ownership of the pub. However, Archie is murdered on Christmas Day 2009 by an unknown assailant (see Who Killed Archie?). Peggy grieves for Archie, but she and various other members of her family become suspects for his murder. Following a police enquiry, local residents Bradley Branning (Charlie Clements) is posthumously found guilty of the murder, though unbeknown to everyone, the actual murderer is Bradley's wife Stacey Branning (Lacey Turner) after Archie raped her months ago. In his will, Archie leaves The Queen Vic to Roxy, who reinstates Peggy.
