Christine Hargreaves was the daughter of Pam Hargreaves, and sister of Charlie Johnson and Luke Ashton.
Raised by her mother, alongside Luke, Christine was blissfully unaware about the existence of her half-sister Charlie - who had been given up for adoption at birth. Charlie worked as a teacher at Weatherfield Comprehensive, the same school that Luke attended. Upon discovering that she was related to Luke, Charlie tracked Pam down but she rejected her. Later, Luke began causing trouble for Charlie at the school and Pam told her to resign from her job and to never contact the family again.
