EastEnders top spoilers sees Sharon Watts' secret exposed and Zack Hudson's teenage son revealed

EastEnders is set for a huge week of secrets and revelations as new storylines kick off across Albert Square.

The week kicks off with an air of mystery surrounding Sharon Watts (Letitia Dean) as her secret is revealed to Bianca Jackson (Patsy Palmer). This encourages Sharon to come clean and be honest with those affected, but circumstances hinder her from telling the truth, but what is she hiding?

Following her failed attempt to come clean, Sharon talks to her brother Zack Hudson (James Farrar) about her secret but they are not alone as someone has overheard their private conversation. It soon transpires that Barney Mitchell (Lewis Bridgeman) is the mystery eavesdropper.

Trying to protect his sister, Zack promises Sharon he’ll find a way to stop Barney exposing her, but a second revelation is soon unveiled.

At Harry’s Barn, Zack confronts Barney, but their conversation takes a turn when Barney starts bleeding from the wound that he sustained during the explosion at The Queen Vic.

Zack joins his former flame Nicola Mitchell (Laura Doddington) and Teddy (Roland Manookian) at the hospital, where the doctors are attending Barney.

But confusion soon surfaces as conversation about blood groups sparks his suspicions about Barney's paternity. Wasting no time in wanting the truth, Zack confronts Nicola who admits he’s Barney’s biological father.

Reeling, Zack heads back to Walford to drown his sorrows. His day goes from bad to worse after a phone call from ex-fiancée Whitney Dean (Shona McGarty).

Will Sharon and Nicola's secrets be exposed to the rest of the Mitchell clan?

Elsewhere, struggling Bianca cannot face being out on the Square and continues to feel like a prisoner. She's reassured by George Knight (Colin Salmon) that she is not responsible for what happened at The Queen Vic.

Kat Slater (Jessie Wallace) offers her support and Bianca begins to open up about her trauma. As the week goes on The Knights try to support Bianca as she tries to face her fears.

Kojo Asare (Dayo Koleosho) gets her some food at Beales Eels, only for a group to kick off at him. Bianca must face her fears to be there for Kojo, but will she make any progress?

Elsewhere, Tommy Moon (Sonny Kendall) returns home and he wastes no time with impressing his parents Kat and Alfie Moon (Shane Richie) after his sweet gesture to a friend in need.

But when Tommy keeps asking to speak to his friend online, Kat risks a row when she's forced to admit she got rid of his computer console. Later in the week Tommy loses his cool but will he lash out again?

Elsewhere, Harvey Monroe (Ross Boatman) feels pushed out by the Slaters as they grieve for Martin (James Bye), leading to him confiding in Kathy Beale (Gillian Taylforth).

EastEnders airs Monday - Thursday at 7:30am on BBC One and iPlayer
