Coronation Street’s Nick slept with fiancee Leanne’s sister recently – but viewers are certain she knows everything and has something dramatic planned

Coronation Street fans reckon Leanne Battersby has ‘figured out’ fiancé Nick Tilsley and sister Toyah Habeeb’s affair – and they need to watch out.

Earlier this year, Nick (Ben Price) and Toyah (Georgia Taylor) ended up sleeping together, as a result of Leanne (Jane Danson) prioritising The Institute over her family and loved ones.

As fans will recall, Leanne has been lured into the mysterious cult by mentor Rowan Cunliffe (Emrhys Cooper) – with Nick and Toyah sharing their concerns over Leanne especially Toyah who was recently diagnosed with germ-cell ovarian cancer.

With no one else to confide in, Nick and Toyah started to grow incredibly close – but it didn’t take long for one thing to lead to another. Following a shock kiss, the pair ended up sleeping together.

Unfortunately, the pair were caught out by Rowan – who snapped a photo of them during a passionate moment.

Showing his true colours, Rowan has since been blackmailing Nick into investing in The Institute’s new resource centre. If he refused, he would tell Leanne about his affair.

And this week, Nick decided to be honest with everyone, and while at the hospital visiting Toyah, he confessed that he was in love with her and wanted to be with her.

However, Toyah suggested they ignore their feelings to save Leanne from The Institute. In a twist, Nick later received a voice message from Rowan demanding a £20k investment by midnight, or he would tell Leanne about his affair with Toyah.

Rowan’s plan failed though when Nick warned him that he would report him to the police for extortion. However, in what would be a huge twist, fans reckon Leanne could actually already know about the affair and is planning her revenge.

On a Corrie Facebook fan page, one person said: “I have a feeling Leanne has known about Nick’s affair for months. What is she up to?”

Someone else added: “Leanne will get revenge by mortgaging the restaurant to pay the institute’s new centre.” A third wrote: “She’s done fraud before so it’s possible.”

Another chimed in: “Sounds like something Leanne would do! I can’t imagine she already knows about Nick and Toyah, but anything can happen.”

Coronation Street airs Monday, Wednesday and Friday at 8pm on ITV1 and ITVX
