The Australian earlier confirmed that he would like to apologise to Rachael and Nathan, after he was rude to the Beyoncé look-a-like while her boyfriend Nathan watched from another room.
During a conversation in the garden Corin said that she felt John James's attitude had got worse in recent days. "He went from being angry, to being alright and now he's gone back," she said.
Agreeing, Mario said that he had told John James he felt "polarised" by his angry personality.
"It's not even anger, it's downright rudeness," Corin replied.
Corin said that she got upset when John James began to make fun of her. "I can take the piss out of myself, but don’t blatantly take the piss out of me because I don’t blatantly take the piss out of anyone else," she explained.
Mario told the former sales assistant that they should try to help John James and prove that he was a good person.
"I can't see good in people that put people down and what he said today was disgusting. You wouldn't dream of saying that in a million years would you?" she stated.
Mario said that John James would regret some of the things he has said when he leaves the house. "He won't be proud when he watches it back," he declared.
Mario went on to say that while John James had upset a lot of people in the house he hoped the retired vehicle body builder would learn from it. "I'm hoping that what has happened tonight will make him realise it; shouting your mouth off doesn't make you a big man," he concluded.
