EastEnders' actor Eliot Carrington actually found out his alter ego Bobby Beale murdered Lucy Beale on Monday, February 16.
Unveiled as the killer in a special flashback episode, Jake Wood who stars as Max Branning in the BBC One soap has revealed Eliot wasn't told the news until earlier this week.
Speaking about the scene where Bobby's heard telling Jane what he had done, Jake said to Scott Mills on BBC Radio 1: "He was incredible wasn't he, Eliot.
"He was amazing, he was like Damien out of 'The Omen'. I was scared, I was scared for myself. It was amazing, he's only known since Monday, I think [that's when] they told Eliot.
"He's tiny, I'm not sure exactly how old he is. What pressure for him but he pulled it off massively. He was great. I think he hadn't had much rehearsal because he found out on Monday and I think he'd rehearsed that once or twice."
The actor also went on to reveal that Jo Joyner who plays Tanya Cross was "very upset" about fluffing her line on Wednesday night's episode, calling Ian Beale by his real name, Adam.
"She, bless her, was very upset obviously. She's a real pro and takes her work very proudly but she did incredibly well she had about three or four scenes after that and we had some scenes together so we just have to draw a line under it and move on. She still now has no idea where it came from or how it happened."
