Letitia Dean says Kathy Beale could be the one to make her alter-ego Sharon Beale "crack".
It was recently revealed that Sharon was behind her husband Ian Beale's (Adam Woodyatt) attack in the Queen Vic, which she orchestrated as revenge for the boat crash, and after Sharon tried to poison Ian with Christmas pudding, Letitia admitted Ian's mother Kathy could uncover the truth.
She told Digital Spy: "She's been battling with Kathy anyway and this accelerates things for her – she's breaking Ian down, ostracising him from his family – although some could say he did most of that himself – and driving a wedge between him and his mum. She's become very good at playing the doting wife!
"Kathy could be the one to make Sharon crack, I think. Sharon knows that Kathy realises something is not right but The Vic will freeze over before she admits defeat! She's determined to carry on with her plan and she needs to be very close to Ian in order to do so."
Sharon lies and tells Ian she is falling in love with him, which Dean believes is a way to further alienate him from his mother.
She explained: "I think Sharon realises that if she doesn't do something pretty drastic all her malicious hard work will be ruined. Ian's shown Sharon how he feels and she hasn't really manipulated him emotionally throughout their marriage as they both entered it aware of the others feelings – or non-existent feelings in Sharon's case.
"She's not pleased about doing it but she knows that telling Ian she's falling for him will absolutely have the desired effect – he won't listen to his mum or anyone else and his world will revolve around Sharon. Perfect!"
