On Tuesday night's explosive episode, Carly's actual partner Justin Fischer admitted that his wife preferred quirky Troy.
In an even more bizarre twist, Justin claimed he was more attracted to Troy's wife Ashley.
It's then that he asks Troy if he'd consider 'trading' wives, with an excited Dean Wells proclaiming: 'Wife swap 'em.'
Thus, the next 'wife-swap' scandal would hit our screens.
But, the whole scene has finally given us some answers into why Troy and Carly were spotted making-out in a park, when they were supposed to be married to Ashley and Justin.
At tonight's dinner party, the discussions of 'wife-swapping' that occurred at the 'boy's night' is believed to spark the romance between the unlikely pair.
While we are still unsure if the pair's love story will play out on screen or off, at least we know how it all began.
This season of Married At First Sight has seen several couples attempt to swap partners - including Carly and Troy, Dean and Davina, and Ryan and Ashley, just to name the ones we're aware of.
