In episode 16 of House Rules Shayn and Andy decide to go head to head with Lisa and Andy but things don't bode well when the couple endure a health crisis!
"This is one of the hardest renovations," reveals Shayne as he reveals he's injured his back the day before.
Struggling to stand, Carly asks him if he should sit for a while.
"No I can't do that," laments Shayn.
"Your health is important to us. I can't have you broken," says Carly as they discuss his health condition on site.
Later they chat to the cameras. "It's impacted me hugely to be honest," reveals Shayne.
"I'm running at about 20-30 per cent capacity a day," he adds.
"I got your back," comforts Carly.
"That's good as mine is f-ed!" laughs Shayne.
