Coronation Street Fans Fear Lisa Swain’s Life Is at Risk After DI Costello Twist
Coronation Street delivered romance and dread in equal measure this week, as DS Lisa Swain finally got her happy ending with Carla Connor — only for fans to be left fearing she won’t live to enjoy it. A mysterious move by DI Costello has sparked a flood of theories online, with viewers convinced Lisa is heading for serious danger.
A Joyous Proposal on the Cobbles
After months of near-misses and failed attempts, Lisa finally proposed to Carla in Wednesday’s (September 3) episode. The moment came after Lisa’s daughter Betsy teased her mum about being “the sharpest detective on the force” yet having no idea what was going on.
Fans were thrilled when Lisa staged her own romantic plan, stepping out of a police car in full uniform to pop the question in front of neighbours on Coronation Street. Carla accepted with tears and cheers from onlookers, and the couple — dubbed “Swarla” by their supporters — exchanged rings as Betsy proudly watched.
The rest of the episode showed the pair celebrating their engagement with friends in the Rovers. For a moment, it felt like happiness was finally in reach.
Work Intrudes on Lisa’s Happiness
But soap joy is never without shadows. Even as she toasted her future with Carla, Lisa’s mind was on her latest case — and her past grief over late wife Becky.
A conversation with DC Kit Green stirred suspicions about Logan Radcliffe, the prisoner who had once given Carla a false lead about a woman called Tia Wardley. Kit revealed Logan was mysteriously moved after a fight following Carla’s visit. The detail made Lisa wonder whether someone higher up, perhaps even DI Costello, was pulling strings to bury the truth.
Lisa confided in Kit, admitting her gut told her there was more to Logan’s tip-off. Her instincts left her fans worried, especially when the episode closed on DI Costello taking a secretive phone call that suggested he was watching both Lisa and Kit very closely.
Is DI Costello a Corrupt Cop?
For weeks, fans have speculated that Costello is bent. Wednesday’s cliffhanger seemed to all but confirm their fears. His cryptic phone call, paired with Lisa’s determination to dig deeper, set alarm bells ringing across social media.
On X, @TheConnorSwains declared: “He’s as bent as a nine bob note! This isn’t about Becky being alive — it’s about him covering up what really happened. I’m betting it ends with an attempt on Lisa’s life.”
Another viewer, @rachbrosnahan, admitted: “Costello saying he’s going to deal with Swain immediately, cut to Lisa saying she and Carla are indestructible… that’s terrifying.”
The timing left many predicting a big downfall arc for Costello, but only after Lisa pays a heavy price.
Fans Fear a Tragic Twist
The episode’s final lines chilled viewers. As Lisa told Carla, “With you by my side, we are indestructible,” many felt the words were a cruel bit of foreshadowing.
@corriecorefour compared the situation to one of Corrie’s most infamous plots: “I can see a Richard Hillman-style moment here — Lisa fighting for her life. That ‘indestructible’ line has doom written all over it.”
Others believe the show could be building to a wedding tragedy. @SwarlaEndgame theorised: “This is going to end with an attempt on Lisa’s life, then a #Swarla wedding. Classic soap setup.”
What’s Next for Swarla?
With Carla and Lisa newly engaged, viewers are desperate for the couple to survive whatever’s coming. But with Costello clearly keeping tabs on Lisa and Kit, and the mystery of Tia Wardley still unresolved, danger is circling close.
@4TheSlowBurn summed it up best: “I’m choosing happiness for today… but Costello is corrupt and the Connor-Swain ladies are in danger.”
Whether Lisa uncovers the truth in time — or whether Costello strikes first — remains to be seen. But one thing is certain: Coronation Street fans are bracing for heartbreak, even as they cheer for Swarla’s love story.
