Coronation Street airs panic for Fiz Brown and Tyrone Dobbs next week, as they are targeted.
They fear a character has returned and is taking revenge, after Fiz dumped her partner Phill Whittaker on their wedding day earlier this year.
Things ended badly for the couple when he learned she had ditched him for her cheating ex Tyrone, but he soon left and agreed to annul their marriage.
