DS Lisa Swain has been juggling her romance with Carla Connor in Coronation Street and the pain of losing her wife Becky. But now her work life is about to cause even more trouble. Now that DI Costello’s behaviour is raising eyebrows, viewers sense Lisa is heading straight into a storm.

Lisa’s Past Won’t Let Her Go

Lisa first arrived on the cobbles in 2021 when she led the investigation into the brutal attack on Nina Lucas and Seb Franklin. That case ended in tragedy with Seb’s death. At the time, Lisa only appeared now and then. Since then, viewers have also followed her romance with Carla Connor. The couple, now nicknamed “Swarla,” finally gave in to their feelings at the end of last year. They’ve had ups and downs but remain popular with fans.

Behind her love life, Lisa has faced struggles of her own. Viewers know she still wrestles with the death of her wife Becky, who died in the line of duty. What troubles Lisa most is that Becky was under investigation for corruption before her death, and she fears she never got the full truth. Lisa’s boss, DI Costello, ordered her to attend therapy sessions but determined to find answers, Lisa snooped through Costello’s emails. She was stunned to find that Kit Green had requested access to Becky’s file.

Coronation Street: Costello Acts Strange

Lisa confronted Kit in the Rovers about why he wanted Becky’s file. She soon realised his digging was not just about Becky but about Costello too. Around the same time, Costello warned Lisa to keep things professional, making her even more suspicious. Then Lisa noticed Kit had written down Costello’s name and a phone number after a call in their shared office.

Things escalated when Costello pulled Kit into the station. He placed him on desk duty after a clash with Underworld client Eli. Kit was told to say it was because of his injuries, but Lisa didn’t believe it. Kit stuck to his story at first, even when Lisa offered to help if Costello was causing him problems. But later, he admitted he also suspected Costello. Fans now think Lisa and Kit could team up to expose Costello as a corrupt officer. They also believe this could clear Becky’s name once and for all.

But many think it could lead to a big promotion for Lisa. One fan claimed that if Costello turns out to be bent, Lisa will be DI by the end of the year. Another said they were manifesting “DI Lisa Connor-Swain” every day. Others predicted Lisa and Kit would rise together, with her as DI and him as DS. Whatever happens next, viewers are sure Lisa Swain’s life on Coronation Street is about to change forever. Stay tuned to Soap Opera Daily for the latest Coronation Street spoilers and news.
