Coronation Street fans 'rumble Costello's link to Becky's death' after clue

There seemed to be massive hints during Wednesday's Coronation Street about what DI Costello was hiding, and whether it was linked to late police officer Becky Swain. Lisa Swain's late wife died years earlier, before she was on the show.

Recently there's been a few questions raised about Becky, and whether she was a corrupt officer. Not only that, but Lisa feared something was going on that may have led to her death, with Becky hit by a car driven by the Radcliffe brothers.

As will as hints from Logan Radcliffe about Becky and what went on, including a mystery person called Tia Wardley being mentioned which led to Logan seemingly being attacked and silenced, we've seen DI Costello acting strangely over some police files. Both Lisa and colleague Kit Green have separately tried to access files linked to a case Becky was working on before her death.

Costello has been keen to stop them both snooping, even putting Kit on desk duty while claiming it's down to a complaint made against him. Kit appeared to see right through him though, before making it abundantly clear he may have something on him.

Costello made it seem as though he was doing Kit a favour, telling him: "Trust me, it's what is best for us. Stick to the story and we will get through this." When Lisa quizzed Kit about the move, confused given it was blamed on Kit's injuries, she didn't get any answers. Instead she got attitude, but later on Kit made his thoughts clear.

He told Lisa that Costello was up to something and couldn't be trusted. Kit couldn't make sense of Costello covering for him, and his claims about why he'd put him on desk duty, while Lisa commented that it could have been worse for him given what he'd been accused of.

Conversation then turned back to Becky's files, as Lisa asked him why he was wanting to read them. He refused to tell her before accusing her of being obsessed with the files.

Further into the episode, Costello asked to speak to Kit who claimed he was "spooked" after he looked into him. Costello told him he didn't want him to lose his way in the force, saying he was a "good cop" and that he punished him this way "for him".

As Kit asked why he didn't just get rid of him, Costello warned that if he carried on the way he was then he'd be out. But it was then very clear that Kit knew something about Costello, as he made light of the situation.

Costello snapped, telling him to remember who he was talking to and saying: "I'm a man of integrity. I have nothing to hide." But Kit, smirking, simply replied: "That's not strictly true that, is it?"

As he got up to leave Costello sternly warned him: "Tread carefully DC Green." So it's clear Kit has something on him, but what is it and what is Costello hiding? Fans think the constant references to Becky and those files will mean Costello knows what she was looking into and perhaps is linked to her death, maybe even orchestrating it.

Taking to social media, one fan said: "The closer we get to the park scene, the more convinced I am that it’s the fallout from discovering Costello’s hand in Becky’s death." Another fan asked: "Why do I think that Kit gonna find out a lot more about Costello and Becky???"

A third fan posted: "I think Corrie will go the route of Costello being involved in Becky’s death and Kit won’t let it go. He’ll uncover something and tell Lisa which will lead to the park stuff and it’ll all unravel. Becky’s name will be cleared and Lisa will be able to move forward." Another fan said: "New theory is that Costello is the bent one, Becky was on to him so he got her investigated for corruption and got her killed."
