Dean recalled: “As we began filming I knew I was about to say my infamous line. I walked to my spot, I turned and just thought, ‘Wow, I really am here. My dream has come true.’

“I then turned to Ramsay and bluntly uttered the line: ‘ Your father was a **** and that’s why you killed him.’”

Dean auditioned for series six in June 2015. He said: “I prayed for it. When I heard I got the part my knees buckled. It was a life- changing moment. My dream had come true. I had to keep it secret for months. I can’t even tell my mother if I am going to be in more episodes. My agent says Smalljon is ‘an impactful role’ and that’s all I can tell you.”

He said: “Dad would say: ‘ When are you going to get a proper job?’ I’d always reply,
