Next week’s Weatherfield is set to explode as the mystery surrounding Becky Swain is finally revealed – and the twist is so big it’s sending both Carla Connor and Lisa Swain into turmoil.

After months of being missing and presumed dead, Becky suddenly returns with a dirty face and a cold gaze.

From a “victim”, Becky is now suspected to be at the center of a series of dark events, and what shocks fans the most: she seems to have had a hand in the mysterious death involving DI Costello.

Spoilers reveal that Becky tried to kill Costello in the hospital – where he was on the brink of death.

She used a junk SIM card, a burner phone and hired a mysterious henchman to buy high-dose anesthetic equipment. Everything was quiet, until Becky stood in front of Costello’s hospital bed, her hand shaking as she held the syringe, intending to extinguish any chance of him waking up. But just as the needle was about to be inserted, Lisa appeared, standing dumbfounded at the scene. Carla’s eyes, after knowing the story, were enough for Becky to understand that her “poor victim” cover had been officially torn apart.

What made the incident even more horrifying: why did Becky want Costello dead? Many fans speculated that Costello was holding data, case diaries or DNA related to a dark network. And Becky was just a pawn being manipulated. But if Becky was the real culprit, Costello was just the first victim in a series of crazy revenge. Weatherfield had never been so close to darkness as it was now.

The drama climaxed when Carla – Lisa – Becky faced each other. Becky slept in Lisa’s bathrobe, wandering around the house as if she were the owner. Carla watched as her soul was turned upside down: the man she loved and trusted was hiding someone with a bloody past. Carla’s blunt words tore apart the peace that had existed: Becky had to leave the house immediately.

With no support left, Becky left in the night, carrying with her a dull look and a deep hatred. And from that moment on, no one could be sure if Becky would stop. Would Costello wake up and tell the whole truth? Or would he die in silence, taking a series of secrets with him?

The killer has been revealed – or are we just seeing the tip of the iceberg?
