Coronation Street fans think they have rumbled Lisa Swain’s ‘plan’ for Becky as they said she is ‘no fool’.

The detective sergeant has been worrying some viewers of the ITV soap as her usual policing suspicions have seemingly disappeared when it comes to her former partner.

Those who follow the long-running show know that the Becky made a shock arrival on the cobbles last month, revealing herself as Lisa’s late wife who has been very much alive and well for all this time.

Lisa was led to believe that Becky had died in the line of duty and she and her daughter, Betsy, were left to grieve for four years until her sudden arrival on Betsy’s 18th birthday.

Lisa’s jaw dropped when she found Becky standing in front of her in the living room of her new home, No. 6 Coronation Street, before Carla arrived home to the emotional scene.

As an emotional Lisa was unable to figure out if what was happening was real, Becky explained that she had been in Spain under another name, having been put into witness protection, following an undercover operation gone wrong.

Betsy also soon discovered the truth about her other mum’s surprise return from the dead, and has since, understandably, wanted to make up for lost time.

But Becky’s company has been proving uncomfortable for Carla, who was recently seen expressing her concerns about leaving Lisa alone with her recently-returned wife as she headed to Ireland for a family funeral.

And it was made to appear that Carla was right to be worried during Friday’s (October 17) visit to Weatherfield as Becky was seen making herself at home at No.6.

During the episode, Corrie fans discovered that Betsy had been arrested and spent the night in a cell, having left home upset after mistakingly leaking her mum’s identity on social media.

Lisa and Becky were stunned, meanwhile, an officer interviewed Betsy and told her that according to DI Costello, she damaged a police car, resisted arrest and then tried to attack him. But Betsy refused to comment.

Later, Costello met up with Becky and spelt out that she needs to disappear back to Spain again or it will be worse for Betsy. Revealing his plan, the detective told Becky: “You need to disappear again, soon. If not DS Swain will have a lot more to worry about than her daughter sitting in a cell for a couple of hours.”

When she refused, Becky told Costello that if he doesn’t assist in her plan, she will report him, telling him he must help her with persuading Lisa and Betsy to go to Spain with her, with it clear she has no regards for Carla.

Later, Lisa was seen filling Carla in on what was happening and when the Underworld factory boss insisted she come home as she shouldn’t be on her own, Lisa said she’d be fine, with Carla unaware that Becky was staying with her.

While some Corrie fans are confused as to why Lisa is being persuaded by Becky, others think it’s all part of her plan and thought they’d spotted a telling moment between her and her colleague, DC Kit Green.

Alongside a clip of the pair at the station, @Fake_TV_Chef said: “This scene (if you can call it that) was so random. Oh, they’re working on something. #Swarla #Corrie.” @EmmaHorsfa28434 replied: “I still standing by I think Lisa is playing Becky let see.”

@JuneGhafur shared: “He’s going to help lisa to bring them down I hope.” @swoosh286 commented: “Spot on! Lisa’s letting Kit do the digging on Costello while she works on Becky. The mug of tea was simply an analogy – him passing her little bits of (comforting) information and saying we’ve got this, sit tight! #swarla.”

@SarahWa58757614 responded: “Absolutely there’s no way lisa isnt a mug shes onto something it’s just a matter of time now Lisa is digging.” @KeeleyTown52229 added: “I honestly believe Lisa smells a massive rat when it comes to Becky & she needs her close to get to the truth. She’s allowing her to do this stuff to nail her. She loves Carla & would only do it for the greater good, she is not a liar or a cheat. Swainy is no fool. #swarla.”
