Coronation Street star Daon Broni has exclusively spoken to Inside Soap about DI Costello’s manipulative handling of Lisa Swain amid Becky’s refusal to leave Weatherfield. Viewers will remember that Costello helped Becky pull off her fake death by identifying the body of Tia Wardley, a homeless woman that he had killed, as Becky.
The dodgy cop also aided Becky’s escape to Spain while keeping up the pretence to Lisa that her wife had tragically passed away.
Since Becky’s shock return, Costello has shown his determination to send his former colleague back to Alicante, even going as far to issue a threat on her life if she doesn’t skip town soon.
But for actor Daon, who plays Costello, it’s not exactly clear cut whether his character would act on his cold words.

“It sounds like, ‘That’s what Costello is going to do, and he’s fully capable of that,” he explained. “And a part of me think that he is capable of doing it, because he’s got a lot riding on this. But I’m going to leave people to decide who the real threat is between Becky and Costello…”
Thus far, Lisa is none the wiser about Costello’s tense dealings with Becky, which is exactly how she and Costello want things to remain. In fact, Costello has gone to extreme lengths to hide his secrets from Lisa, given that the pair are constantly in each other’s orbit at Weatherfield Police Station.

“It’s very much a managing of the situation,” Daon explained. “Me and Vicky [Myers, who plays Lisa] spoke about that, in the way the relationship develops, it’s almost like a coercive control relationship, because Costello is managing Lisa and the information that she receives, and managing what she perceives the situation to be. It’s a really enigmatic relationship between the two.
“There’s an element of massive manipulation,” he added. “Costello is probably a narcissist. He’s very much aware of his position in the community, and how to maintain that aura of respectability…”
