MAFS UK first look sees honesty box make an explosive return

Married at First Sight's troublemaking honesty box is set to return in Tuesday's episode.

In a first look clip of the episode, the couples all get together to reflect on the experiment so far. Following Monday night's expert sessions, some of the couples were on track for growing closer but that seems to melt away in the teaser.

Polly kicks off the teaser looking confrontational, then says: "If they do come in together then I'll f***** call it out later" seemingly talking about Charlie and Eve. The couple were working through rough patches in tonight's episode but look cosied up in the first look.

Polly then pulls Charlie for a chat and accuses her of bullying. Charlie is then seen sobbing, saying "I don't want to do this anymore"

Fans have taken to Twitter to slam the 31-year-old fitness coach, Eve, accusing her of not treating Charlie well. One user penned: "Eve is the literal definition of emotionally unavailable."

Another reacted to the clip of Polly confronting Charlie, saying "How is Charlie getting blamed for this and not Eve?". While it's unclear why Polly would call out Charlie, we'll have to tune in to find out.

The first honesty box of the series unveiled with a question read out by Caspar Todd, asking: "What is the biggest obstacle in the way of our happiness?" To which Emma Barnes replies "Definitely sex."

Caspar came under fire from fans after he admitted that he didn't find Emma attractive and on Monday's episode expert, Mel confronted Caspar about his comments. Caspar responded by stating that his comments were the truth and he "didn't want to lie."

His response was not well-received by viewers who urged on Twitter that the couple should 'end the marriage' over Caspar's 'rude' comments.

The teaser ends with an explosive back and forth between Polly and Adam. She is emotional and tells the camera: "I just want him to be honest" and Adam shares his own frustration, saying: "If Polly continues to talk to me like a child then this marriage isn't going to work."

Married At First Sight UK airs Monday to Thursday at 9pm on E4.
