While viewers are still debating who the real villain is between Becky and Costello, Coronation Street delivers another twist: Kit Green unexpectedly pieces together a crucial clue, escalating the Costello-Becky-Swain affair to a completely different level of tension.

Kit initially appeared in Weatherfield as a young, vulnerable but fairly upright police officer.

Since being drawn into the Costello attack, he’s been subjected to numerous ambiguous statements, cautionary tales, and orders to “don’t ask any more questions” from his superiors.

Each time he tried to dig deeper, Kit was pushed in a different direction, making him increasingly suspicious.

The situation only truly escalates when Becky Swain – the presumed deceased wife of DS Lisa Swain – returns to the old town, unleashing a never-before-told storm of secrets. Coronation Street Wiki

Becky, a former colleague of DI Costello, was reported dead in an accident while on duty. Now, her sudden reappearance at the very moment Costello is attacked leads Kit to begin piecing together the story: could all these years have been a fabricated narrative for the police officers? The interrogations, the files, Costello’s requests to “close it all”… everything suddenly looks very different when juxtaposed with the image of Becky secretly monitoring Lisa and Betsy’s daughter during their time away.

The crucial clue Kit discovers directly relates to Costello’s phone and movement records before his attack. These aren’t just random call logs; they piece together to show Costello interacting with people he previously denied, appearing in places he claimed he “never went.” He begins to realize: Costello isn’t just a victim in this story; he might be the one playing a double game for years, especially in concealing the truth about Becky.
