Mimi is presented as a character who behaves in ways which are polar opposites. For example, she has no qualms about selling drugs to children and behaving in a violent manner. However, she also has strong maternal instincts and shows compassion for others. For example, when Chesney Karib (Qasim Akhtar) reacts badly after consuming drugs, she and Paddy care for Chesney by feeding him and ensuring that he sobers up safely. Later, when Yvonne Karib (Kelli Hollis) accuses Mimi of being an intolerant racist, Mimi retorts by describing the racism that Paddy faced when he arrived in England from Ireland. Yvonne and Mimi realize that they share love for their own children and would do anything to ensure their happiness. Also, Mimi is someone upon whom Libby Croker (Pauline McLynn) can depend when she seeks advice or assistance.
