passage: List of Coronation Street characters (2000)
Charlie arrives in Weatherfield with her husband Matt in November 2000, having bought Natalie Barnes' (Denise Welch) house. She is first seen breaking up a fight between Sarah-Louise Platt (Tina O'Brien) and David Platt (Jack P. Shepherd), and Sarah recognises her as her English teacher at school. Charlie does not properly settle in Weatherfield due to her snobbish attitude and also due to the fact that most of the teenage residents were her students. She makes friends with Emma Watts (Angela Lonsdale), but takes an instant dislike to Maxine Peacock (Tracy Shaw). It soon becomes apparent that Charlie is an alcoholic, due in part to the fact that she had been given up for adoption as a child. Charlie tracked down her birth mother and was horrified to discover a student of hers, Luke Ashton, was her half-brother.
