In 2004, Kate makes friends with Little Mo Mitchell (Kacey Ainsworth) after being the first person to learn that she had been raped by a man frequenting The Queen Vic: Graham Foster (Alex McSweeney). Kate urges Mo to tell her what has happened but does not react well as it sparks childhood memories of when her mother was raped. Kate takes Mo to the police to report the crime and supports her until Mo leaves Walford. Mo returns for the trial with her baby son, Freddie. Graham's mother approaches Mo and meets her grandson, before commenting about another grandchild she will not be allowed to see. Kate reports this to the prosecution's legal team, and so Graham is convicted of rape.
