The 14-year-old schoolgirl, played by Brooke Vincent, starts attending a Bible study group and soon ends up with two new men in her life – boyfriend Ben, 16, and God.
Sophie even takes a vow of chastity, according to reports in The Sun.
Parents Kevin and Sally Webster, played by Michael Le Vell and Sally Whittaker, are shocked by Rosie’s turn to religion in the ITV1 soap – but they are relieved that she’s not out chasing men like 18-year-old Rosie (Helen Flanagan).
Sally apparently tells Sophie: “I don’t know where you get that leaning from. I was boy-mad at your age and you don’t get it from Rosie – she’d sooner give up breathing than boys.”
