After a deeply divisive week away, the couples come back together for another dinner party. Emotions are extremely raw, and pretty much every individual in the experiment has an axe to grind.

The Couples' Retreat continues amid a sour atmosphere, with Bec's comments from the first night fuelling a venomous divide in the group. And with allegations of betrayal and interference, the trip culminates in a very shocking decision.

It's time for the Couples' Retreat, and there's a mood of celebration as the newly-weds celebrate their progress. Well, until Bec makes a joke about another couple's intimacy milestone, which sparks a heated clash that divides the group further.

The fourth Commitment Ceremony has arrived, and the couples must face their toughest relationship challenges yet. But could it be the end of the road for yet another marriage when the ceremony descends into chaos?

It's the sixth dinner party, and it turns out textgate still has plenty of legs - and venom - left in it yet. Bec has a foolproof plan to defuse the tension: an apology. But apparently that involves shifting the blame onto someone else.

The drama keeps on coming as the couples enter Feedback Week. The bad blood over Bec's leaked texts is still bubbling, and more confrontation is in store when the Partner Swap leaves relationships and loyalties hanging by a thread.
