And it would seem Mel and Layton may have been correct, as photos taken during the filming of the experiment seemingly prove Bronte and Harrison didn't have as genuine a connection as they have repeatedly claimed to have.
During Monday's episode of the show, Bronte and Harrison were seen starting the new week by giggling together on the sofa whilst reading about the “partner swap” task.
Yet, in reality, that scene was filmed after they'd spent another whole day apart.
Prior to pretending to smile while shooting the scenes, Bronte looked strained whilst out on a solo shopping trip across Sydney and Harrison had spent the day walking the city alone.
An insider tells Yahoo Lifestyle: "None of the cast ever thought Bronte and Harrison's relationship was legit, no matter what they would say on camera.
"They barely spent any time together off-camera and were like entirely different people once the producers said 'action'."
Harrison on his edit: 'I'm worse'
During an appearance on The Kyle & Jackie O Show on Tuesday morning, Harrison hit out at the MAFS editors after Jackie 'O' Henderson said: "Talk me through the edits of things, because watching it, you do look like you have a gaslighting problem and it does look like you deflect a lot."
"That's the oldest trick in the book, the gaslighting trick – all you have to do to make a gaslighter is edit out my arguments," he said. "If [Kyle] and I have a conversation, and I edit out all your good points and I just talk over you, you look like the gaslighter, that's the oldest trick in the book!"
"So you're saying that you are nothing like what they're making you out to be?" Jackie questioned.
"No, no, I'm worse," Harrison responded. "No, I think there's some truth in the edit, I don't want to talk about the edit too much, because I'm really struggling with watching it because I know what happened and then watching it on screen I'm like, this is not - it's so choppy."
When asked by the hosts if the editors are changing the narrative of the show, Harrison told them he believes "they're cutting the show to fit a storyline, to the point where some scenes don't even make sense".
When asked if he and Bronte ever decided to make a pact to stay on the show despite not having feelings for each other, Harrison said: "Nah, she tried at the honeymoon, she pulled me aside and said, 'Oh look, you know, we could just get through this,' and I was like, 'Bronte, that's not what I'm here for.' And then she gave me an example of Brent and Tamara from another season... they hated each other and they wrote stay every week, that was the fakest relationship ever, and she goes: 'We could just do that,' and I'm like, 'That's not what I'm here for.'"
When Kyle Sandilands asked him to clarify why he was on the show, Harrison added: "Bronte or whatever, I was there for a relationship."
The radio hosts also asked him what he's learned from watching the show, with the reality star saying he has learned that he doesn't listen to anyone else in an argument and only tries to poke holes in what they're saying, also adding: "I've learned how to gaslight better!"
Harrison also shed light on why he ended things with Bronte over text before the pair both chose to stay another week, with the reality star saying he wasn't getting the answers he needed from Bronte about their future, adding he was "falling" for her.
He also shared that it wasn't him that 'ended' the relationship, it was Bronte who said she wanted to go to Perth, and his text message simply 'confirmed' the split.
Kyle jumped in to ask if Harrison and Bronte are going to stay together, with the MAFS star saying: "Bronte and I are sorting things out," with the radio host asking if they were sleeping with each other, to which Harrison confirmed they are having "pretty great sex".
However, Jackie then caught him saying he "did" like Bronte, hinting the pair don't make it past the end of the show.
