Her surprise re-appearance comes as she battles to save Sonia Jackson from being jailed for the murder of Reiss’ wife, Debbie Colwell.

viewers know that Reiss killed his own wife after being left in crippling debt.

Comatose Debbie required round the clock care and it had started to become a costly habit for Reiss.

Amid his new engagement and baby on the way with Sonia, Reiss decided that the best way to regain some control over his finances was to stop paying for Debbie’s care and as such was forced to murder her.

However, in a cruel twist, Sonia was jailed for the crime after being the last recorded visitor of Debbie.

Convinced something is amiss, Bianca has become hellbent on proving that Reiss has had some part to play in Debbie’s death.

She has been seeking revenge in order to expose his true colours and has now come up with a cunning plan in order to get the truth once and for all.

Speaking to Kat in The Queen Vic, she at first appeared to insinuate that she had forgiven Reiss as she planned to move-in with him.

Bianca said: “Guess what, I’m moving back into Sonia’s.

“I’m going to be there 24/7, working on the campaign [to free Sonia] with Reiss.”

Kat replied: “He’ll love that!”

Bianca then continued: “Best thing that could happen for Sonia.

“Him and me living together, working together.

“Then, when that slimy little toad slips up, I’ll be there to catch him.”

Kat responded in shock at what Bianca was planning amid her belief that Reiss is innocent.

Bianca insisted: “He’s hiding something Kat. I know he is.

“So, I’m going to move in there and I’m going to be his best mate and then I’m going to watch him crack.
