The promotional footage shows 27-year-old Jessika in an explosive showdown with 43-year-old Mike Gunner, who tells her exactly what he thinks of her betrayal of her TV husband Mick Gould.
The Queensland electrician tells the blonde bombshell he wanted to "see if you were adult enough to accept responsibility for your actions", to which Jess hit back: "Do you not think I've faced the music enough?"
The tension between the pair was clear, but it's not the first time Jessika and Mike have exchanged heated words.
During last week's dinner party, Mike confronted the office administrator over a claim she made about Mark betraying his wife Ning by staying in the experiment for "the wrong reasons".
"To me, it seems like you can create drama out of fresh air," Mike told Jess.
"Words are powerful darling and I don't think you realise that. It's not about Instagram and selfies and trout pout."
