Lisa Gormley revealed that her character wants to make a new start with Liam (Axle Whitehead), after it was made common knowledge that Heath (Dan Ewing) is fathering her unborn child.
She told TV Week: "It's got to a point where she has no more cards to play and she needs to prove to Liam that she definitely wants to be with him.
"She does that by taking up an idea he's suggested before, 'Let's just go!'"
However, the actress declared that younger sister April (Rhiannon Fish), ex-lover Heath and Irene (Lynne McGranger) are all opposed to the move.
"April is devastated because Bianca is thinking of going without reconciling with her - literally running away," Gormley said.
"Irene is always forthcoming with the words of wisdom, and she doesn't agree. She thinks they should stay and face their problems.
"[Heath is] pulling out every stop he possibly can to prove to Bianca that he does want to be a part of the child's life. He's not giving up - he's trying to prove to her that he's more supportive than Liam will ever be. He also wants them to be a family."
Bianca has been having a full-blown affair with the River Boy, and the baby news has caused uproar between Liam and Heath.
