EastEnders has revealed Bianca Jackson’s new scheme amid her suspicions about Reiss Colwell.

In today’s episode, Bianca made a dramatic return to Walford, as she marched into The Vic demanding answers from Reiss.

Her sister Sonia is currently in prison for Debbie’s murder, but it was in fact Reiss who killed his wife back in July.

Her depression diagnosis, which was revealed shortly before her exit in June, will also be revisited as Kat will urge to her to see the GP about her erratic behaviour.

In scenes that will air next week, Bianca continues to play Reiss and makes a fake gesture towards him before Sonia’s plea hearing.

She spots Reiss with a mysterious letter and becomes more determined to free her sister. But Kat tries to deter her, and she eventually agrees to back away.

Though it isn’t long before Bianca gets curious and she gets her hands on the letter when Reiss isn’t looking – and is shocked by what she reads.

At that moment, Debbie’s parents arrive at the house with a solicitor, to read the contents of Debbie’s will. While Reiss asks Bianca to leave, she naturally listens in, and Debbie’s requests raise her suspicions further.

Determined to get the truth once again, she meets up with Brenda and Hugh in the café to speak to them about Reiss and Debbie’s marriage.

She also wants to tell Kat about her suspicions, but Kat instead tries to persuade her to book a GP appointment.

Devising a new scheme, Bianca takes Freddie’s microphone that he uses for birdwatching and hides it in No.25 so she can record a confession from Reiss.

She then begins to get Reiss drunk as she tries to get him to confess. Bianca’s plan is a success as Reiss starts to open up, but the pair are interrupted by Freddie. Has Bianca been caught?

Later in the week, Freddie and Bianca meet in the café, and he tries to talk to her about her health, but she dismisses his concerns. Will she get the help she needs?
