Overview: Martin spends his day on edge, concerned that Sonia knows the truth. He desperately tries to work out where his wife is but when Sonia returns home, she's perturbed as to why Martin feels the need to check up on her. She informs a relieved Martin that Sarah has decided to leave, her affair with a married man apparently over. However, just when Martin begins to relax, events take another turn for the worse. Sharon uses Vicki's absence as a tool to make digs at Dennis, telling him he has driven her away. Dennis knows that there is more to her ill-feeling and throws himself into his relationship with Zoë. He's on the verge of reciprocating Zoë's strong feelings for him when something stops him literally in his tracks. Alfie decides that he knows just what will repair his relationship with his wife and Andy informs Paul that he owes him a favour.
