Coronation Street’s Carla Connor has suffered a low blow after she tried to expose Becky Swain’s plan to win back her partner Lisa. After faking her death, Becky recently returned to the cobbles, sneaking her way back into her wife Lisa and daughter Betsy’s lives. Carla, Lisa’s partner, has had to put up with Becky’s presence for Betsy’s sake, but started suspecting the ex-cop may be up to something.

In tonight’s episode, Becky was discussing Christmas plans with Lisa, Betsy and Carla, saying she’d postponed her return to Spain. Betsy was elated to have her two mums with her for Christmas.

“And you, obviously, too, Carla,” she added hurriedly.

A pensive Carla then said she’d be spending Christmas with Roy anyway. “You three knock yourself out though, eh? Enjoy it,” she told them before leaving.

Later on, Kit Green called at Lisa’s to inform her that their boss Costello was planning on retiring to the Lakes in September.

“Doesn’t make sense,” Kit said as Lisa seemed equally puzzled.

When Becky asked Kit was he’d do about it, he replied defiantly: “My plan is to keep digging.”

At Underworld, Kit caught up with Carla to tell Costello had planned to retire before he changed his mind.

“Well, he changed his plans about the same time Becky rocked up,” he said. “That’s a bit of a coincidence, don’t you think?”

Carla reflected on the possibility of Costello and Becky being in it together, but said they couldn’t proved it. Kit suspected Becky may be behind the attack that landed Costello in hospital and was determined to let her know he was onto her.

“Just been to see Carla. She’s necking scotch like a bottle of water,” Kit told Becky after bumping into her. “She’s saying she really wants to see Lisa,” he added, as Becky said she’d tell her but headed to Underworld herself instead.

In her office, Carla continued drinking as Becky warned her to stay away from Lisa while she was in that state.

Carla revealed she’d booked a two-week trip to the Canary Islands for her and Lisa. “Got no use for it now, have I?” Carla said, insisting she wanted to see Lisa “to tell her I’m giving up”.

“You’ve won, Becky,” Carla said. “Well played. You got what you wanted,” she insisted as she attempted to get something incriminating out of Becky.

Becky agreed that she and Lisa “[were] meant to be together” and that Carla never had a real chance. “And I think it’s probably best if you stay away from Number 6 now,” Becky said.

“But that’s my house,” Carla protested, but Becky insisted Lisa needed a clean break to move on. Becky left, advising Carla to go to the Canaries to get over the breakup.
