Coronation Street spoilers follow from Friday's episode (November 29), which is available to watch now on streaming service ITVX but hasn't yet aired on ITV1.
Coronation Street's Tracy McDonald has inspired a major revenge plan by giving Leanne Battersby some unexpected advice.
The unlikely allies were drawn together in Friday's episode after Leanne discovered the truth about her sister Toyah and ex-partner Nick's secret relationship.
Toyah and Nick were already caught out once earlier this year after betraying Leanne with a brief affair.
Since then, Nick has split from Leanne but has chosen to keep her in the dark about his decision to keep pursuing a potential future with Toyah.

In Friday's episode, the truth dawned on Leanne as she finally spotted the clues that Nick and Toyah were hiding something from her.
The final straw came when she investigated the mysterious Tenerife holiday that Nick had recently booked. She found out that he'd chosen a romantic couple's suite to enjoy alongside Toyah.
Probing further, Leanne also secretly watched the secret lovers from afar as they met up for a rendezvous at the Chariot Square Hotel.
Leanne held back from confronting the pair but later broke down in front of Tracy, telling her everything.

Tracy encouraged Leanne to return to her roots rather than being walked all over, telling her: "For good or bad, you are a Battersby. And if you want my advice, you better start acting like one."
Leanne ultimately decided to play the long game, telling Nick that she needed his support following the sad death of her father Les and the stress of preparing for Rowan Cunliffe's trial.
As Leanne asked to move back into the flat, Nick felt highly awkward over the situation but reluctantly agreed.
Leanne then checked back in with Tracy, who was baffled to see her moving back in with Nick. She asked Tracy to stay out of it, confirming that she fully intends to get her revenge in good time.

She warned: "Let me tell you something – I'm nobody's fool. Nobody's."
Coronation Street's new producer Kate Brooks recently announced that Leanne's revenge will be one of the stories taking centre stage at Christmas this year.
Speaking at a Corrie press event, Brooks told Digital Spy and other media: "I remember really vividly the Battersby sisters coming onto the street in peak Spice Girls era. They barrelled onto the street, little Sporty Spice and Scary Spice.
"Just tapping into how they were as Battersbys was really important, and that all comes to the forefront on Christmas Day and it doesn't end well for anyone.
"They do spend Christmas together, so at least they're together! Just don't ever spend Christmas Day with your ex and your sister!"
Coronation Street airs on Mondays, Wednesdays and Fridays at 8pm on ITV1 and streams on ITVX.
