Nearly two decades later in October 2018, Kim returned in a week of episodes that saw the character being revealed to be the mastermind behind the events of the show's longest-serving local family, the Dingles, being endangered of losing their home, with her step-grandson Joe (Ned Porteous) carrying out the plot in his bid to exact revenge on his former stepmother Charity Dingle (Emma Atkins) for her mistaken involvement in Chris' death. The week of episodes saw Kim being pushed off a balcony at Home Farm by Charity's ex-fiancé's mother, Faith (Sally Dexter), before being sent back to prison for dangerous driving. After returning to the show on 14 March 2019, Kim became the show's main antagonist once more, and her second stint mostly followed her one-off relationship with Joe's legal guardian Graham Foster (Andrew Scarborough) - who later turned out to be Kim's third husband. This triggered the events of the "Who Killed Graham?" storyline, wherein Kim and her business associate Al Chapman (Michael Wildman) planned to kill Graham after discovering that he had been extracting money from them.
