Coronation Street fans are certain DS Lisa Swain is hiding something major.

Coronation Street’s DS Lisa Swain, played by Vicky Myers, is suspected by fans to be hiding a significant secret unrelated to Joel Deering.

The character, who first appeared on the soap in 2021, has been involved in numerous major storylines, most recently the case of missing Lauren Bolton (Cait Fitton).

Viewers will remember that the troubled young girl disappeared earlier this year, only to reappear on the cobbles in July. It was then disclosed that Joel Deering (Calum Lill), known for grooming and abusing young women including Lauren, was responsible for her disappearance.

Joel found himself being blackmailed by Lisa Swain’s mischievous daughter Betsy (Sydney Martin) after she caught him attempting to intoxicate her friend. He eventually threatened Betsy, leading her to reveal the truth to her mother.

Since then, Joel’s ‘true’ nature and crimes have been exposed, with Lisa, Lauren, and Joel’s ex-fiancee Dee-Dee (Channique Sterling-Brown) resolved to bring him to justice.

However, the soap took a dark and suspicious turn this week. At the beginning of the episode, Dee-Dee received a mysterious voice message from Joel, suggesting he was contemplating suicide, reports the Liverpool Echo.

The police were able to locate Joel’s last known whereabouts and discovered a suicide note and his deserted car. Lisa later informed Dee-Dee that it was likely Joel had taken his own life.

Throughout the episode, viewers were left puzzled by Lisa Swain’s peculiar behaviour.

Carla Connor (played by Alison King) expressed concern for Lisa, who was seen grimacing in pain and feeling nauseous outside the cafe.

While some fans speculate that she may have killed Joel, others believe they’ve figured out the real issue. They took to social media to share their theories, suggesting that Lisa’s daughter Betsy might have assaulted her due to their strained relationship.

One viewer on X speculated: “I’m wondering if Betsy has hit Swain – maybe,” Another added: “There is definitely something up with DS swain after tonight’s #Corrie, who thinks it’s Betsy who is taking her anger out on her.”

A third fan theorised: “So I’m going with Swain has had an altercation with Betsy. Maybe the anniversary of Becky’s death is coming up and instead of Lisa listening to Betsy she is distracted by her work phone. Betsy snatches it and throws it, then pushes Lisa who falls and hurts herself.”

Another viewer shared their thoughts, writing: “I don’t think Swain would kill Joel. I am going down a different path and sayin Betsy as hurt her.”

A fifth suggested: “Is Betsy hurting Swain? Can’t believe she has anything to do with Joel’s disappearance.”
