Coronation Street Fans Predict DI Costello’s Shocking Downfall After Hidden Clue Emerges
A Major Twist Leaves Weatherfield Reeling
Coronation Street viewers are convinced they’ve spotted proof that DI Costello’s downfall is near, following a subtle but telling twist that aired this week. The ITV soap’s mysterious head of CID, played by Daon Broni, has been at the heart of Lisa Swain’s emotional storyline — but fans now believe his calm façade is cracking.
Lisa Swain’s Past Comes Back to Haunt Her
Lisa, who recently found happiness with Carla Connor, was left shattered when her supposedly deceased wife, Becky Swain, returned to Weatherfield — very much alive. Her reappearance exposed years of secrets, including time spent in Spain under a new identity after a failed undercover mission.
Costello’s involvement raised eyebrows when he confirmed Becky’s story, hinting at deep ties to her past. His quiet manipulation and watchful demeanor have left fans questioning his motives, especially after he was seen observing Kit’s conversation with Carla before unexpectedly offering Kit a promotion.
The Clue That Started the Theories
During a recent episode, sharp-eyed fans noticed a newspaper pinned behind Costello’s desk with the headline: “Police Arrest Gang Members…” — a detail many see as a hidden nod to the ongoing Emmerdale County Lines storyline.
Theories exploded on social media. “This was no coincidence,” one fan declared. Another wrote, “These two [Celia and Costello] could definitely be mother and son. Becky’s debts might not have been personal — maybe they were gang-related.”
A Crossover That Could Change Everything
Speculation is now swirling that the Coronation Street and Emmerdale crossover — already confirmed for January — will expose Costello as a corrupt officer, linking Weatherfield’s criminal underbelly to the County Lines operation in Emmerdale.
As one fan summarized on X (formerly Twitter): “I really believe the Corriedale crossover is gonna link the Becky/Costello/Swain storyline in Coronation Street to the drug gang in Emmerdale.”
If true, DI Costello’s secrets could unravel both soaps in a dramatic shared climax — and fans can’t wait to see him fall.
