Controversy
Contestants Dean Wells and Davina Rankin were involved in a cheating scandal that blindsided their respective partners, Tracey Jewel and Ryan Gallagher. Dean and Davina had planned to write "leave" at the commitment ceremony, but instead Dean chose to stay with Tracey and deny any wrongdoing when Davina called out his lies over their affair. Dean further infuriated fans when during a "boy's night" he led a conversation on wife swapping and asked the other grooms if any of their wives' mothers were attractive.
