Coronation Street's Natalie Gumede has revealed her abusive character Kirsty Soames will stop at nothing to ensure Tyrone Dobbs can't live a happy life without her.
Kirsty and Tyrone's wedding is set to end in tears when the former policewoman is injured in a dramatic fall.
Despite months of abuse at the hands of former policewoman Kirsty, mechanic Tyrone (played by Alan Halsall) is planning to marry her so he can gain custody of their baby daughter Ruby.
But the night before the big day, controlling Kirsty discovers her fiance has been having an affair with his friend and confidante Fiz Stape (Jennie McAlpine).
Gumede said: "I think something's died inside for Kirsty. Tyrone was the love of her life and I think that's the one piece of happiness she thought she had. And just when she thought everything was going to go right, it all goes wrong and her world's fallen apart.
"She's so in love with Tyrone and she hates him for what he's done, so if she can't have him, nobody can.
"She's not willing to just walk away and let him be happy. No way!"
She added: "I don't think there are any limits as to how far Kirsty will go.
"I don't think it's as calculated as planning ahead, but she's an intelligent girl and she knows how to manipulate.
"But I think there's still a pang of guilt there. She still loves him and she still wants to be with him."
Viewers of the ITV1 soap are left wondering whether the furious bride will go through with the wedding as she walks down the aisle in a striking purple gown, with Fiz looking on.
Corrie bosses have remained tight-lipped about whether the nuptials go ahead, but a spokesman said: "What happens next will have viewers open-mouthed in shock."
New pictures also reveal that Kirsty will fall down the stairs after a blazing row later that night.
The ex-cop confronts Tyrone about the day's events and his relationship with Fiz, and after reaching out to hit him, falls down the stairs.
She is then set to use her injuries to falsely claim Tyrone - who got close to Fiz after she learned of his ill-treatment - has been abusing her, leaving him facing a court case.
McAlpine revealed that as the rest of the street side with Kirsty, Fiz - who previously went to jail for her late husband John Stape's crimes - becomes the villain.
She said: "Fiz and Tyrone both become the villains. But I'm the scarlet woman. They think it's a terrible thing that Fiz has done to break this young family up and she should have kept well away from Tyrone.
"So Fiz is fighting a losing battle, standing up for Tyrone on the street, because she's saying Kirsty is the violent one and no one believes her."
Halsall revealed: "Tyrone's like Weatherfield's doormat, and everyone walks over him. Because that's the kind of guy he is, he wears his heart on his sleeve, he'll do anything for you.
"He's had such a bad childhood that he just wants to get away from that. He wants the stability of a family life and he'd do anything for that. And so he finds himself in these situations.
"I just don't think he sees himself ever being happy. It's actually quite sad.
"But who knows, maybe he will be happy with Fiz in the end."
Coronation Street has been praised by domestic abuse charities for tackling the sensitive storyline. Halsall's performance has been recognised with a nomination for best serial drama performance at next week's National Television Awards, while Gumede is nominated for best newcomer.
The action-packed episodes to be screened on ITV on Monday January 21 at 7.30pm and 8.30pm are full of unexpected twists and turns - and even after Tyrone and Kirsty return from the church the drama continues with tragic consequences.
