Coronation Street is set to introduce a new character in the Abi Webster and Stefan Brent storyline.

The ITV soap recently aired shock scenes as Jack was arrested after confessing to DS Swain that he was

behind the accidental fire that damaged Stefan’s office.

After being taken into custody, Jack insisted to Swain that he never meant to start the blaze, though there wasn’t much hope for the teenager as the DS confirmed she planned to formally charge him.

While Adam Barlow tried to help Jack, the solicitor later admitted to Kevin that there wasn’t much hope for him, suggesting Jack plead guilty to a lesser charge and avoid a trial. He also suggested Jack could be looking at time in a youth offenders’ facility.

In new scenes set to air next week, Jack prepares for his day in court. Following the plea hearing, Jack and Kevin talk, though Abi spots Stefan clash with a woman called Coral in the corridor.

Abi is later approached at the garage by Coral, who reveals she is Stefan’s wife and Corey’s mother. How will Abi take this?

Later, as they prepare for Jack’s sentencing, Abi pulls him and Kevin in for a hug – but what will be the consequences?

In other Coronation Street news, a recent trailer for September’s episodes has teased evil Joel Deering’s downfall, with Dee-Dee and Swain coming together to take him down.

Swain declares that they will “do whatever it takes” to get him, with Dee-Dee suggesting it could be “the beginning of the end for Joel Deering”.
