EASTENDERS has been rocked by a shock death as a major secret has been revealed in today’s episode.

Viewers watching today saw the aftermath of the dramatic car crash after Teddy Mitchell and Zack Hudson drove into a lake.

The shock events came after Zack tried to save his biological son Barney from his murderer mother Nicola Mitchell and his gangster family.

Teddy discovered the truth and took over his son’s Harry’s plan to get rid of Zack.

However they were followed by Billy, Honey, Nigel and Harry who watched the car sink into the lake.

And when Teddy emerged they simply accepted that Zack was dead, barely giving him a second’s thought.

Returning to the Square, they told Phil what had happened and with Sharon away, he went to break the news to Vicki who was being supported by Linda Carter.

And it’s safe to say Vicki didn’t take it well.

Storming around to the Mitchells, Vicki began hammering on the door as Barney asked what was happening.

But despite Nicola telling the family to ignore the screaming and banging at their front door – Vicki got in.

“You evil witch!” screamed Vicki after kicking her way through the door, followed by Linda and Phil.

Turning to Barney, Vicki told him: “Your mum, she has been lying to you. Teddy ain’t your dad – Zack is.

“And they have all just had him killed.”

But is Zack really dead?
