When asked who was most likely to take on Foreman Dan out of all the Blockheads Sonny's name was mentioned the most.

"I've taken Foreman Dan on a couple of times," Sonny grinned.

As for who wins those on-site battles? Sonny said "you never win" while wife Alicia crowned Foreman Dan.

As well as a few site clashes there have been plenty of secrets so far on The Block and there is one couple everyone agrees is the best at keeping them up their sleeves.

Who did the cast think were the best secret keepers? One couple was a clear winner: Emma and Ben.

Considering they not only kept their wine cellar idea a secret until the Domain Open House and Buyers Jury challenge but also successfully hid Emma's pregnancy until weeks into production, that seems fair!
