Married at First Sight couples show manipulative behaviour and other signs according to body language expert

One body language expert has come forward to share the reasons why he reckons certain Married at First Sight Australia couples show manipulative behaviour.

Scott Taylor, an FBI-trained behaviour expert, who has been closely following the reality TV series, took to TikTok to share with viewers a 10-minute long behaviour summary of Tuesday's episode.

In the lengthy clip, Scott discussed Jack Dunkley's allegedly 'manipulative behaviour'.

The episode in question saw bride, Tori Adams, opening up about her marriage with Jack.

She revealed she couldn't support her hubby after sticking by his side for weeks upon weeks of drama.

Jack has found himself at the heart of a bunch of accusations, including being 'flirty' with Sara Messa.

He was also accused of 'smacking her butt' and kissing her on the cheek.

Talking about the MAFS groom in his TikTok video, Scott explained: "His words just lacked substance and lacked conviction, which is something we've come to expect.

"He went to face and neck touching - he does that for a couple of reasons....the repeat touching is a self pacifying gesture, that's the body saying the brain has got some discomfort."

Scott then claimed he predicted Ben Walters' actions ahead of last week's dinner party antics.

"Called it, I picked it from the start and I've stuck to my opinion of him throughout which has been very very low," the expert went on.

Jack has also recently came under fire over an offensive 'whale' comment he made on Tuesday's episode.

Fellow groom, Timothy Smith, then confronted Jack, saying: "You're a sh*t person.

"When we were at the pool, and you had the audacity to say, 'What, are the whales here today?'" while he, Tristan and Lucinda lounged in the sun.

Jack has since spoken out about the offensive comment and claimed it was

simply 'outrageous banter'.

"I walked into the pool one day, and I think it was Jade and Lauren or Jade and Sara... two very attractive, fit girls that are very happy with their bodies," he said.

"I did a bit of a walk and said, 'the whales are out today'. It was a joke – not a joke I would make to anyone and everyone."

It's clear viewers have been loving the latest season to grace their screens with many rushing to social media to share their praise.

"This is gonna be a great series," penned one X user.

A second quipped: "Buckle up folks, this season looks JUICY!!"

"Why am I already obsessed with the new season…?" asked a final viewer.

Married at First Sight Australia continues tonight at 7:30pm on E4 and streaming on Channel 4.
