While the housemates were confined to the bedroom, Josie and Govan began teasing John James about having bad breath and smelly feet. John James told them to stop it as he had a headache, but after the joking continued the playful insults turned sour.
As the two, who have flirted since they entered the house, continued to trade insults, Josie repeatedly said: "Is it nominations tomorrow?" John James then snapped, saying that the way she was going she wouldn't have to wait long to be out. He added: "I've already told you, you don't have to worry about that. I'll be coming out to see you."
Josie continued by making fun of John James's hair, to which he replied: "At the end of the day, I can cut my hair - but you can't do anything about that face."
When the garden was opened, John James turned to Josie and said: "That was your warning." Josie replied: "It's okay, John, because unlike Rachael I won't beg for your friendship, I'll just cut you out of my life." The 24-year-old Australian then said: "If you want to go hard, I'll go hard."
The smokers questioned Josie over the exchange while at the carousel, which she initially brushed off. In the house, John James told the other housemates that he had laid in to her because he had an headache and she "kept going" at him. He said that it was too much, and that Sunshine has started to insult him as well.
As Josie returned to the house, she told John James: "You can dish it out, but you can't take it." He replied: "When have I ever dished it out to you?" When John James pushed the Diary Room button, she then said: "Off to have a moan about me in the Diary Room, are you?"
Nathan joked that John James was "having a go at another one of my women", and Josie agreed, but said that he can't go around intimidating people. She said: "It was Rachael's turn, now it's my turn. He's off in to the Diary Room to have a little bitch. He's a little bit of a drama queen, is our John."
She then added: "I've always stuck up for John. But I've just seen his true colours now. I think he knows that he picked on the wrong person now."
