They won the wallpapering challenge and the $3,000 that went with it, but on one condition the money had to come from another couple, or couples', budgets.
Katrina knew it wouldn't be easy: "It's hard, I know. Still, at the end of the day, we really need that $3,000."
Each couple had compelling reasons why they could not afford to lose $3000.
Polly: "If the girls take three thousand off us that's game over. We can't do a house on fifty dollars."
Josh was ready for a fight: "If they take three grand off us then we'll go after them."
While everybody awaited the girls' decision site foreman Keith was concerned that Josh had allowed the accumulation of rubbish at the front of his property to get out of hand: "If this was a union job I'd be calling for tools-down. It's just not on."
Josh saw the error of his ways and cleaned house.
He also had bigger fish to fry with the body-corporate meeting looming and the girls' decision pending.
Katrina and Amie agonised over how they'd extract their prize money: "They're going to hate us."
They decided to take the money based on winnings and that meant $2,000 from Josh and Jenna and $1,000 from Rod and Tania.
Polly breathed a sigh of relief: "We could have been packing our bags. I feel like a huge weight has been lifted from my shoulders."
Rod understood and didn't feel it was too much of a hit. Tania wasn't quite so forgiving: "I think if anyone should be annoyed it's us. We've worked just as hard for our money and we haven't won nearly as much."
But the biggest anger came, not surprisingly, from Jenna: "I think they resent us, plain and simple. We've won the most prize money so they see us as the biggest threat. I'm also frustrated by Polly's massive sob-story. They don't have any money because they blew it. That's not our fault. I think the sisters should have taken a thousand from each of us. I'm not going to forget this."
Will the sisters' decision cause enough bad blood to rock The Block?
