After David brought up the ex-mole's previous claim that he was visited by aliens, the friends waited until they were in private to comment upon their fellow finalist.
"I don't think he believes he's been abducted by aliens at all, he just said that to try and get in here," Josie argued.
"You can't trust the mole 'til you get out of here," JJ agreed, prompting Josie to chip in: "I don’t trust him at all now."
The 25-year-old sales rep then accused Mario of nominating tactically over the course of the series, as JJ pointed out that it appeared Mario had only gunged himself and David in the 'Nasty Nominations' to ensure that they had the numbers to face the public vote.
"If he's been voting for me every week, why didn’t he put one over my head?" Josie asked. "I wish I put one over his head now.
"I do think he's got a few hidden secrets, a few dark hidden secrets. I see him weighing up how to answer his questions sometimes."
She continued: "He's got quite a dark way of thinking as well I've noticed. He said normally when you have happiness it's at somebody else's expense... I thought, 'You dark, twisted individual'."
Later in the afternoon, following a heated discussion about Mario's nomination choices, Josie again made suggestions about his perceived gameplaying.
"When I first met the mole in lockdown he said, ‘I'd do anything, anything to get in Big Brother’," she revealed. "Fair play to him, he’s here."
