EastEnders' Bianca Butcher is to have an "explosive showdown" with two-timing love rat Connor Stanley.
The feisty redhead - played by Patsy Palmer - will be furious when she discovers her mother Carol (Lindsey Coulson) has been having a saucy affair with bad boy Connor (Arinze Kene), who is supposed to be dating troubled teenager Whitney Dean (Shona McGarty).
An insider revealed: "When all of the lies are revealed, it's going to be very hard for both Whitney and Bianca to handle. It really is the ultimate betrayal by Carol and Connor.
"It's going to be an explosive showdown. Carol has betrayed her entire family, and Bianca will find her actions unforgivable. This could ruin their relationship beyond repair - especially given what happens to Bianca next."
However, Bianca's famously fiery personality reaches boiling point when she attacks cheating Connor and leaves him unconscious.
While the rest of the family hope they can conceal her actions, furious Connor isn't prepared to let her get away with the attack and reveals all to the police, who immediately arrest the young mum.
The source assed to Inside Soap magazine: "Bianca blames him for all her family's problems. She can't contain her fury, and just wants to punish Connor. But it's a decision she'll live to regret.
"Carol reckons she can take the rap, but when Connor comes round, he tells the cops that Bianca attacked him. Prison will be hard on Bianca but when she returns home she'll have scores to settle - especially with her mother."
