Robby and Mat aren’t the only ones on The Block who have been staying mum this year.

In a major plot twist for the show, Emma is 12 weeks pregnant with a baby boy. The couple found out she was expecting on the very same day that Scotty Cam rang them to say they had finally made the cut for The Block.

“It was a bit wild. But I said to Ben: ‘We are doing it and we will just take it as it comes!’ and we have been for the past six weeks,” she explained of diving into the unyielding chaos of The Block while pregnant with her first child.

Ben and Emma are emotional after sharing the news that they are expecting a baby boy.

Making matters potentially even more stressful for the couple is the fact their son is due in auction week.

An elated Scotty and Shelley Craft were eager to share the happy news with the rest of the teams on their site visits.

Upon arriving at Alicia and Sonny’s place, Shelley teased of The Block baby announcement: “What is the best piece of news that someone on The Block could announce?”

“That they haven’t copied someone else’s ideas,” Alicia said, clearly still stewing on the whole steam room fiasco.

Although the couple were momentarily distracted by the thought of a pitter patter of little work boots on site, they quickly launched back into detailing their displeasure.

Scotty was only too happy to stoke the fire of their fury, asking: “I still don’t know why they are going to give you the caravan if they’ve done nothing wrong?”

Just moments before the host had reacted with shock when Han and Can told him they had planned to hand the caravan over to Sonny and Alicia should they win.

“I would rethink about giving away the caravan,” Scotty said, reminding them it was worth $260,000.

Han and Can are upset to be accused of copying by Sonny and Alicia.

An obstinate Can argued: “You can’t put a price on integrity.”

“I’m turned off the whole challenge. We are there to create a cool bath house room. The fact that it’s been tainted with questioning our integrity is disgusting.”

When explaining their side of the story to Scott and Shelley, Can this time pointed the finger of blame at the site chippy. The pair claimed they had never set out to copy Alicia and Sonny’s work.

Instead, they argued their carpenter had steered them into following the lead of Sonny and Alicia, without making it clear how much work had gone on behind the scenes to get approvals for the design.

The fallout from the copycat spa room was being felt all over The Block, with most of the other teams empathising with Sonny and Alicia and casting doubts on Han and Can’s version of events.

“I understand why she’s upset. This isn’t just a challenge. It’s $260,000,” Britt reasoned.

The incident also made Alicia and Sonny decide to take a more selfish approach to their build.

And so, when their tilers the Cursio brothers sought permission to install a rock feature wall at the day spa for Britt and Taz, Sonny and Alicia told them it was no go.

“They won $120,000 worth of kitchen stuff. We don’t have anything … We need an X factor,” Sonny explained of punishing Britt and Taz for Can and Han’s mistake.

Alicia added: “It’s nothing personal with Britt and Taz but in light of what has happened with the girls, we need to rein it in now.”

Before coming on to The Block, the couple had been doing it tough financially and emotionally.

Pressure to provide for his family coupled with having to chase people to pay their plumbing bills, had left Sonny strained.

His tearful story put the couple’s eagerness to cement a win on The Block in a new light.

An emotional Sonny reveals the pressure he feels to provide for his family in the face of customers not paying their bills.

“It would be nice to relieve Sonny of some of that pressure,” Alicia said through tears.

It also explained why the couple were so upset to discover Han and Can had flagrantly copied their plans for the Hepburn Day Spa challenge.

“It’s the same as, I found out about House 5’s plans this week but I don’t go and dig up my backyard to put in a wine cellar,” Sonny reasoned.

In addition to facing the wrath of Sonny and Alicia and the fifth degree from Scott and Shelley, Han and Can have other problems on their hands. Or should that be, at their feet?

When Foreman Dan stopped by for an informal chat about how they were going, asking lots of questions about their herringbone floors, it was clear he was about to point out a major flaw with their floor.

Having finally sorted out their bumpy concrete slab, the time-consuming business of laying the floorboards was well and truly underway at long last.

Unfortunately, nobody had thought to check which direction the patterns should run to transition seamlessly into the adjoining rooms.

The result was bedroom floorboards which pointed one way, and living areas which did the reverse.

Dan notices that Han and Can’s floorboards are going to face different directions throughout the house.

“Building 101, once you do the floorboards one way in one room, the whole house has got to go that way,” Dan chided. “I am so confused. They are supposed to be project managing this. These are the things you’ve got to look out for. It’s a huge mistake.”

Can had a foolproof way to fix the stuff up: closing the bedroom doors and praying the judges wouldn’t see it.

“You won’t even notice it. There’s that many big rugs as well,” she continued as she literally swept another problem under the carpet.

The girls were more optimistic about their decision to delete one of the loungeroom windows to replace it with a wine fridge.

A sensible plan when you consider that after drinking enough plonk, nobody is ever eager to face the daylight.

Speaking of wine, now that Robby and Mat’s secret cellar is somewhat out in the open, everybody is looking for their own game changing plans for their houses.

Can tells Dan her strategy for dealing with the floor mismatch will be to shut the doors on the offending rooms.

Mostly because Dan kept wandering from house to house telling people that they also needed a secret weapon for auction day or Robby and Mat would have it in the (underground goon) bag.

Scratching for ideas, expectant dad Ben had the novel idea of building a slide that extended from the rumpus room into the pool.

“Hear me out. It could be a good selling feature. If you had kids, it would keep them entertained for hours,” he argued.

Once Dan and Emma stopped laughing and realised, he was serious, the befuddled foreman admitted Ben’s plan had caught him off guard.

“I don’t think we have ever had a plan like it on The Block,” he offered diplomatically. “That’s a first and a weapon. I like it.”
