EastEnders showdown - Sharon and Kathy come to blows on the Square
EastEnders will feature a good old-fashioned hair-pulling scrap between Kathy Beale and Sharon Mitchell as Kathy makes her return to the Square.
Sharon (Letitia Dean), who has been suspicious of hubby Phil's behaviour recently after she found messages from a mysterious 'K' on his phone, is shocked when she spots his ex-wife Kathy (Gillian Taylforth) in The Arches.
Kathy had been presumed dead for a decade following her car crash in South Africa, but she made a brief reappearance in February this year for EastEnders' 30th anniversary.
"The reaction we're holding off is the reaction from Ian and Ben. They're the two most exciting people," said executive producer Dominic Treadwell-Collins.
"It's big, heavy, heavy stuff. And then throwing into the mix Jane as well, because we always said, Ian's married a woman like his mum, and, oh, how would Jane and Kathy get on?
"And Jane and Kathy aren't going to get on... and it's all quite sparky."
Sharon and Kathy almost met in an episode last month as they both arrived at Kings Cross station at the same time.
Kathy's husband Gavin Sullivan (Paul Nicholas) is a nasty piece of work and looks set to be one of the most memorable villains the soap has ever seen.
"He makes Archie Mitchell look like a Care Bear," said Treadwell Collins.
Kathy will face off with Sharon on September 14.
