Peter (played by Chris Gascoyne) and Toyah (Georgia Taylor) have been conducting a secret relationship for months now.
The need for secrecy was vital as Peter previously had a tumultuous marriage with Toyah's sister Leanne (Jane Danson), while Toyah was herself married.
Despite the fact that Toyah has since ended her marriage, the couple decided to keep their romance a secret for fear of upsetting a heavily pregnant Leanne.
However, in scenes set to air on February 1, their clandestine relationship will face a new challenge as Peter finds out Toyah had been undergoing IVF treatment with her husband.
