Coronation Street fans are buzzing with theories after a new September trailer showed Lisa Swain appearing horrified and emotional. The preview hints at danger for her daughter Betsy, a possible engagement to Carla Connor, and her meeting with the mysterious Tia Wardley, but it's Lisa's reaction that has viewers speculating wildly.
In the clip, Lisa is seen gasping and dropping a glass of red wine, leaving fans to wonder what has left her so stunned. Many believe the twist could be linked to her late wife Becky Swain, with some suggesting Becky might actually be alive. One fan commented: "Face of a wife to whom has just found out her dead wife is alive."
Other theories include a connection to DI Costello, who some viewers suspect is corrupt, or a DNA twist involving Betsy. Another fan speculated: "I’m thinking either Tia spills the tea on Costello, or Tia is Becky’s daughter from a secret affair." The possibility of a car accident involving Betsy has also been raised.
Despite the speculation, fans will have to wait to see the truth unfold. Coronation Street airs Mondays, Wednesdays and Fridays at 8pm on ITV1 and ITVX.
