Speaking at a press event for the soap's festive episodes, Wadey also teased storylines for 2026, including the arrival of Ancona as newcomer Bea.
Wadey commented: "You may have seen we've just announced Ronni Ancona joining the show, which I am very, very excited about. I'm a huge fan of her work, and she brings such a unique tone to it."
He continued: "I was really interested in this having a story that has a bit more of tragedy comedy coming through it. It's a story in which she's an old school friend of Linda's, and she's called Bea.
"The character, Bea, arrives, and her memory of Linda is very different to Linda's memory of Linda."
However, it's not just Linda for whom Bea is set to create stories, as she drags Billy (Perry Fenwick) and Honey Mitchell (Emma Barton) into her chaos.

Wadey added: "And Bea is the sort of character who might attach herself to people. So she kind of comes in and gets to reacquaint herself with Linda, but it's also going to be a big story for some other characters. Billy and Honey are going to be big in the new year and will be involved in that story as well.
"So it's a story which, as a team, every time we watch it and read it, we love it, we laugh, and we cry, and it's really, really fun."
