Eight strangers in the mountains, tonnes of alcohol, and cameras all around, nothing could possibly go wrong. But in the sixth episode of “Married at First Sight,” things did go very wrong. The show’s remaining couples, Bella and Michael, Nicole and Keller, Mark and Monica, plus the ill-fated Jess and Dave, all came together for a dinner party in the Blue Mountains on Wednesday's episode.

At first things appeared to be very cordial, but then Bella, who was all over her partner Michael, started questioning everyone on whether or not they had been having sex, to which everyone declined an answer. “It’s such a normal thing. I can talk about this with my girlfriends all the time,” she said. “Would you not talk about this with your friends?”

To this Monica replied, “Yes, I’d talk about it to my friends,” implying Bella wasn’t her friend yet. Keller told Bella that she was really open about her relationships and that she couldn’t think that it’s normal to tell everyone about her or anyone’s sexual life. He also admitted that he does have a big mouth, and appreciated the fact that Nicole pulled him into line, just as she did when he ended up slut-shaming Bella.

Bella had just started sharing a story saying, “I’ve been in a lot of relationships where...” To this, Keller angrily retorted, “I bet you have!” while pointing a finger at her. “After sleeping with a guy after one day, I bet you have been in a lot of relationships!”

To this, Nicole exclaimed, “Why would you say that?” and walked off. The others were obviously in a state of shock, especially Bella and Michael. Things got very serious at that point of time.

Bella's husband, Michael, then started taking digs at Keller and his tattoos, telling him that the tattoos on his knuckles surely show how he is self-made, in a sarcastic tone. In response, Keller appeared to have belittled Michael's profession, saying he wouldn't take advice from a fashion designer.

On social media, however, commenters have criticised Bella for her choice of conversation topic. Some viewers thought Keller's reaction was only expected.

"Married at First Sight Australia" airs Mondays to Wednesdays at 8:30 p.m. on Nine.
