Desperate not to give Pete and Carly the advantage, strategy came into play when the pair were deciding who to award with the win.
“Giving them an extra five points could potentially put them above us, and maybe knock us out... I'm thinking strategically now, not how much I love the rooms,” said Shayn, 33.
While Carly, 31, admitted she was "struggling with trying to figure out who had done those spaces".
However things didn't go according to plan, and after host Johanna Griggs told teams of Shayn and Carly's strategic voting decision, they ended up with egg on their faces...
...as the room they chose was in fact created by Pete and Courtney.
“They're playing a dangerous game,” exclaimed Tim, 32.
“I don't like like this. I don't like this at all,” Mat, 27, added.
Pete, 32, had some final words of warning for Shayn and Carly: “They'll find themselves in the last renovation with no one wanting to support them, give them space, help them out. They'll be very, very alone.”
