Coronation Street is pushing its crime storylines into darker and sharper territory, and DI Costello now stands at the centre. For months viewers believed he was a steady hand in Weatherfield’s chaotic police force. Then the truth surfaced. His corruption runs deeper than anyone expected. Actor Daon Broni now hints that Costello’s downfall is approaching fast.

DI Costello’s Perfect Image Crumbles

Costello first appeared as a calm and controlled leader who worked closely with DS Lisa Swain to bring down Joel Deering and to seek justice in Mason Radcliffe’s murder case. He was strict, patient, and determined. He looked like the officer everyone could rely on.

The illusion shattered when Becky Swain returned from the dead. Costello had announced her death after she was struck by a getaway car. Yet the real story exposed him. Becky had been undercover. Things went wrong. Costello helped her vanish to escape the criminals she had crossed. His actions now appear far from heroic. They show a man who bends rules for personal gain, then lies to cover his tracks.

Becky’s Return Pushes Tension To A Breaking Point

Becky’s arrival shook the entire police team. It also sent Costello spiralling. He wanted her out of Weatherfield and back to Spain at any cost. His desperation escalated last week when he admitted to having Tia Wardley killed. He used that confession as a warning to Becky, telling her he would do the same to her if she did not leave the country.

The revelation has sparked a dangerous standoff between them. Each encounter feels like a quiet battle where every sentence holds a threat.

Daon Broni Teases Darker Days And A Reckoning Ahead

Speaking about the twist, Daon Broni said he was stunned when he learned where Costello’s character was heading. He believed the detective would remain strict but fair. Instead, the writers veered him into morally complex territory to keep viewers guessing.

The actor says the audience has reacted with a mix of shock and excitement. Many thought Costello was one of the few trustworthy officers left. Now they see him as a man hiding layers of manipulation and fear.

Broni confirms that more details about Tia Wardley’s death will surface soon. He also hints that viewers may learn whether Costello’s threats are real or strategic. He says Costello’s limits will be tested and his choices will soon reveal how far he is willing to go.

Kit Green Gets Pulled Into The Power Struggle

Costello tried to silence Kit by giving him a promotion. The offer came with quiet conditions that demanded loyalty. Kit took the role, but both men know it is a complicated bargain.

Broni believes Kit sits dangerously between two forces. He wants to impress Costello, yet his bond with Lisa makes him doubt every step. The actor suggests Kit may side with Lisa. The tension between them feels like a sibling rivalry mixed with professional distrust.

On Set, The Actors Play A Strategic Game

Broni praises Vicky Myers, Jacob Roberts, and Amy Cudden for pushing him creatively. He compares his scenes with Amy, who plays Becky, to a game of chess. Every look and every line is loaded. The scenes with Vicky and Jacob add a different energy, showing how shifting alliances can change the tone of the entire storyline.

Costello’s Future Looks Dark

The actor confirms that things will get darker before they get better. He says Costello has behaved badly and deserves consequences. He hints that viewers may see those consequences in the coming episodes.

As for Lisa and Carla Connor’s wedding, he believes Costello has ruined any chance of an invitation. Becky remains deeply connected to their lives. Lisa appears done with Costello’s lies, and Broni admits that those bridges may be burned beyond repair.
