"You're not even my real mum, so leave me alone and let me be sad about my own dad," Vinny growled, as a tearful Lisa insisted that she just wants what's best for him.
Later, Vinny appeared to double down on his denial too, lashing out at Liv when she popped in to check on him after Lisa begged her to.
"Oh, this is where you're hiding? I'm so sorry about your dad," she began, before he snapped back: "Why are you you lying to everyone? Slagging him off to mum... what's that all about?"
"He beat you up," she said. "He admitted it to me. Look at my face... He hit me and he kicked me because I stood up to him. He was a bully and a abuser, and he beat you again and again. Look what happened on the stag night, and on the day he was supposed to be getting married. You could've died."
