By Thursday it was romped that the woman was in fact Faith (played by Sally Dexter), the care for of Cain (Jeff Hordley) and Chas (Lucy Pargeter).
Viewers choose remember that Zak (Steve Halliwell) had an affair with Faith, his fellow-clansman Shadrach’s wife, over 40 years ago, which resulted in the ancestry of Cain.
With Zak’s history of cheating, Lisa (Jane Cox) begins to anxiety next week that her ex-husband will stray again.
Her reveres are realised when Faith begins flirting with Zak in front of her.
Wracked with regret over Joanie’s death, Zak has been acting oddly and snapping at Lisa.
Later on, a troubled Lisa admits to her daughter, Belle (Eden Taylor-Draper) that she believes Zak is having an affair.
In scenes set to air on Thursday, the drama comes to a head at Lisa’s birthday band in The Woolpack.
Thinking she has heard Faith make a play for Zak, Lisa bombards over and an almighty row erupts.
Has Lisa got it all wrong? Or has Zak been unfaithful yet again?
