EastEnders star Laurie Brett has been speaking about the soap's upcoming plotline that will see Lucy Beale (Hetti Bywater) killed off.
"All I can say is that there are some really brilliant scripts, and Adam Woodyatt's [Ian] performance is outstanding," said the actress. "I think the nation should prepare themselves for total devastation. There are scenes being filmed that, if they don't make you cry, you must have a heart of stone. People need to order Kleenex in bulk."
Plans to have Lucy be at the centre of a new whodunnit plot were revealed back in February as show bosses announced that, in the wake of her death, Ian will begin to question just how well he knew his daughter.
Speaking to this week's Inside Soap, Brett admitted that Jane's own grief will also be an important part of the storyline: "Don't forget, Jane brought up Lucy as her own daughter. I think she will be there for Ian, but I'm not sure how much room Jane will have to be that rock. She's going to be grieving as well."
However, the actress also confirmed that Jane wouldn't now be a permanent fixture in Albert Square: "Jane can't stay too long because I have to go back to Waterloo Road!"
During its 29-year history, EastEnders has included a number of high-profile whodunnit mysteries, among the most memorable being the murder of Archie Mitchell in 2009 and the shooting of Phil Mitchell in 2001. Of the demise of Lucy, a show statement teased recently:
"No-one knows exactly what happened to Lucy on the night she died, except very few people - even the person responsible for her death."
