after finding her fiancée in a very compromising situation with her estranged wife Becky. Becky has been a sticking point in Swarla’s relationship ever since she came back from the dead, but in next week’s scenes, Carla decides enough is enough.

The drama plays out as Lisa stands Carla up – then Carla finds her at home with Becky…

“Lisa is supposed to be meeting Carla for a romantic lunch date, but she never shows up,” our Corrie source explains. “When gutted Carla gets home, she finds freshly-showered Becky descending the stairs wearing nothing but Lisa’s bath robe!

“It certainly looks damning, and Carla’s heartbroken at the idea that Lisa could’ve cheated – it’s enough for her to end their relationship for good.”

Little does Carla know, this is the just latest of meddling Becky’s attempts to come between her and Lisa. Earlier, when Becky gets wind of her wife’s lunch plans with Carla, she gets drunk in the street, forcing the detective to take tipsy Becky back to No.6…

“Hammered Becky starts lamenting to Lisa about everything she’s lost,” our spy continues. “Lisa innocently shoves her ex in the shower to sober her up, which Carla misinterprets.

“Through her kind-hearted attempt to help scheming Becky, Lisa has lost the love of her life.”

It’s not the only mischief that Becky gets up to next week, either. When she receives an ominous funeral wreath that reads “Rest in Peace – Again!”, she becomes certain that Costello is behind it.

Snapping a secret picture of some teenage girls at the Precinct, she forwards it to Costello – and he is horrified to see his daughter in the image.

“Becky has made it very clear to Costello that if he gets in the way of her plans, she’ll target his daughter,” our insider reminds us. “They have tense words on the phone, but neither of them is aware that Kit is listening in to the call. Whatever he hears, it makes him seriously suspicious…”

When Costello fails to show up for work the following day, Kit’s detective instincts are piqued – and it’s not long before he discovers that Costello has been attacked.

Sharing his suspicions with Lisa, he suggests that Becky could be responsible – but is she really capable of such a violent act?

With Carla calling time on her relationship, is this really the end of her and Lisa? And, with Carla out of the picture, what lengths will dangerous Becky go to in order to win Lisa’s affections?
