Coronation Street star Claire Sweeney has said that her character Cassie is still harbouring a lot of resentment towards her mother Evelyn (Maureen Lipman).
Earlier this week Cassie returned to the street, having been whisked away by Evelyn in order to get her sober from drugs, and she wasted no time in tracking down Tyrone (Alan Halsall) to reveal that she is his biological mother.
When Tyrone met Evelyn for the first time several years ago, she lied and told him that his mum was dead, while simultaneously keeping her new-found relationship with Tyrone a secret from Cassie.
"There's a lot of anger there. And it's not just about Tyrone, it goes back to childhood," explained Sweeney.
"There is a scene coming up where she talks to Tyrone about why she is the way she is and about her childhood and about her relationship with her mum, who was very cold, never hugged her, never told her she loved her. It was quite a cold relationship really, she even kicked her out when she was a teenager. And so there's a lot of resentment.
"You know, fundamentally she does love Evelyn - she's her mum after all - but she finds it hard to forgive the things she's done to her as a teenager growing up then ultimately even as an adult. She's continued to lie about her and she abandoned Cassie's baby on the steps of a police station.
"Cassie believes they could have worked something out to keep Tyrone in the family. And then Evelyn has gone back and reaped all the benefits of being a grandma without Cassie [knowing]."
She continued: "She's just never had that loving environment or the family. She's had bad men, she had a mum who didn't want to know.
"All she wants is to be loved and be part of a family. That's evident in scenes, simple things just like sitting having a cup of tea and watching the kids get ready and stuff. You know, she's never had any of that. But she wants part of it. And the fact that Evelyn has had that and kept it from her and then told him she was dead is a lot for her to deal with."
Coronation Street continues Mondays, Wednesdays and Fridays at 8pm on ITV1 and ITVX.
