EastEnders spoilers follow.
EastEnders' Zack Hudson will suffer a brutal attack next week, days after issuing Nicola Mitchell with an ultimatum.
Recently, Zack discovered that he is Barney's biological father, from a secret affair he had with Nicola 16 years ago. Zack asked Nicola to tell Barney the truth, but Nicola was desperate to keep it from her son and ex-partner Teddy - going so far as to blackmail Sharon over her night with Grant to keep her from spilling the beans.
Sharon told Zack about Nicola's ploy, who later sought out Nicola and told her she should tell Barney he's his dad or Zack will.
Next week, a stressed Nicola goes to extreme lengths to prevent the truth from coming out, with Zack set to be attacked in the process.
