Becky Swain’s web of lies and manipulation is about to unravel in the most terrifying way as her final move sends shockwaves through Weatherfield. The truth about Costello’s assault becomes the first thread to pull loose. After the corrupt officer is found brutally beaten, Kit Green begins piecing together clues—clues that all lead back to Becky. He shares his suspicions with Carla, who is drowning her heartbreak in alcohol after splitting with Lisa. Kit’s instincts sharpen when he discovers that Costello and his wife quietly purchased a home in Coniston—through a shell company created exactly one week after Becky “died.” The timing is too perfect to ignore.

Meanwhile, Becky intensifies her psychological grip on Lisa. Just before Christmas, Lisa receives a message from Carla asking to be removed from their mortgage. Hours later, Carla posts a picture of herself sipping cocktails abroad. What Lisa doesn’t know is that Carla never reached her destination. Hurt but determined to hide it, Lisa forces a smile as Becky steps into the emotional void. Becky massages her shoulders, whispers that Carla has moved on, and insists nothing stands between them reclaiming the life they once had. She even kisses Lisa’s neck in a calculated move to pull her closer.

But Becky’s plan fails spectacularly. Lisa’s heart still belongs to Carla. She texts the absent factory boss, telling her she loves her and would do anything to make things right. Becky sees the message—and realizes her control is slipping.

Then Christmas Day brings chilling news.

Roy tells Lisa he tried contacting Carla in Lanzarote, only to discover she never checked into the hotel. At first, Lisa assumes it’s a misunderstanding, but by New Year’s Eve, Carla is still missing. Her silence becomes impossible to ignore. Sarah grows alarmed when Carla stops replying to work emails—something Carla would never do. She alerts Kit, who immediately reopens the mystery surrounding Costello’s attack.

Kit learns the injured officer muttered three bizarre words to paramedics—nonsense at first glance, until Kit realizes they correspond to a precise map reference. But when he follows it to an isolated flat, the place is empty. No Carla. No answers.

Kit’s next stop is Costello himself. Again, he gets nothing useful.

What Kit doesn’t know is that Carla had been there. And that Costello isn’t talking because Becky is hiding in his bathroom, listening. When Kit leaves, she comes out and thanks the wounded officer for protecting her secret.

Back home, Becky grows impatient. Lisa refuses to leave for Spain until she speaks to Carla face to face. Becky knows that if Carla returns—if her voice, her truth, her presence is restored—everything Becky has engineered will collapse.

So Becky decides to end the uncertainty herself.

Frustration turns to fury. Fury turns to calculation. And calculation turns into a final, catastrophic decision.

Becky takes drastic action to “clear” Carla from Lisa’s path once and for all—an action that spirals into horrifying consequences. Lives are suddenly at risk, and the truth about Carla’s disappearance is about to explode in a way no one in Weatherfield is prepared for.

Becky’s final move is here. And it is deadly.
