Two innocent spouses are manipulated and betrayed by their partners who finally act on their affair at a gut-wrenching, booze-soaked dinner party on Married At First Sight.
"They're cheating now," the stunned experts inform us on Wednesday night as Dean savages the nape of Davina's neck with the same bestial urgency he eats this cake with.
In the Uber on her way to the dinner party, Ashley makes an accurate prediction which provides the perfect segue to the explosive evening.
Given she plans on having an affair with someone else's husband, Davina decides to quietly enter tonight's dinner and not draw attention to herself.
As Ryan tells the boys how he plans on being with his wife Davina forever, she informs the gals she has different plans for her marriage.
"There's nothing there," she admits as she takes a seat on the lounge next to Dean's wife Tracey. It's a bold move — one motivated by selfish destruction. But Davina has a plan: befriend, manipulate and betray Tracey.
Tracey brags how Dean's a perfect husband to her.
As they move into the dining room, Davina insists on sitting across from Tracey and Dean.
"Trace, do you want some water," she asks while holding up a glass pitcher, hoping the offer of hydration will make up for the fact she's stealing her husband.
Davina then starts complimenting Tracey like a drunk mean girl.
"I genuinely enjoy talking to you — probably out of everyone. I feel like you and I are very similar," she says.
Tracey returns the favour by saying she loves Davina's Instagram and Davina is elated to finally have her hard work recognised.
While all this is going on, the usually-cheery Jo looms in the background. She's devastated about her crappy, non-existent relationship to Sean.
And all the other couples across the table rub her face in it by smothering each other in affection. Jo goes to a real dark place.
Meanwhile, Nasser has pulled up a seat next to Tracey to tell her she's a fool for believing Dean's in love with her and she almost spits out her hummus.
Davina hears this conversation and runs around to pull up a seat. Tracey's in a weak moment and Davina knows it. And she's going to take full advantage of it.
"I'm going to give you a word of advice — one woman to another woman — just look after you," Davina — who's only looking after herself — tells Tracey. "I'm saying this 'cause I love and respect you." Davina's just really thoughtful like that.
"I feel like you're a pretty switched-on girl," Davina adds.
Tracey's a desperate lady in a land of uncertainty. Like a kangaroo who's just been hit on the highway by a Toyota Camry, she laps up any sympathy and attention that comes her way.
"I am! Of course!" she says, still unaware she's being manipulated.
Davina continues doling out sage pieces of wisdom that will work in her favour.
"I feel like Dean may not be your perfect person. Whatever he's doing right now, he's thinking about himself," she advises. "It would make you look worse if he dragged this on for three weeks. You need to stop."
Down the other end of the table, Ashley continues to replicate every relationship I've had with past boyfriends.
Through Ashley's screams, Blair persists in revealing her gross sexual desires. "Take me! Ravage me! Smack my butt!" is the phrase we hear and if someone ever told me to "ravage them" during sex, I think I'd laugh at them.
I immediately excuse myself to go find the secret cheaters because, at this moment, they're less offensive than Blair being ravaged.
Secluded at the end of the table, Davina and Dean hatch a plan to eventually leave their partners for each other.
"These guys are cheating now," expert John Aiken informs us as he and the other experts watch CCTV footage from the underground garage.
As Dean and Davina try organise a time to meet again, they get busted. Tracey comes and takes a seat next to Dean — aka, her husband. But that doesn't deter Davina from pursuing the affair.
"I really wanna kiss you right now," she whispers to Dean before they walk out of the dining room together and run off to a hidden courtyard.
They're breathless. Someone could walk in and find them at any moment. If their partners walk in, it could be catastrophic. But they don't care. They've been waiting all night for this moment.
"We're such bad people," Dean says as he runs his hand up Davina's thigh and ravages her neck, as Blair may say.
As they continue to nuzzle each other, we're shown sharp cutaways of Tracey in a nearby room bragging about how secure she feels in her marriage.
"I feel respected," she says.
But back in the hidden courtyard, as Dean gropes Davina, he says something about his wife that is the final kick to the boob.
"No offence to Tracey, but her looks are not her best quality," he grunts.
Suddenly, Jo eating alone in a restaurant on Valentine's Day looking at all the other couples suddenly seems enviable.
