On Monday night, Gina, Dexter, Wolfy and Dan were put up for eviction after the housemates nominated live and face to face.
But Wednesday night saw a Big Brother 2013 secret revealed, in the form of the safe house.
Rather than leaving the show tonight, two housemates will actually face a 'fake eviction'.
In reality, the chosen two will be living a life of luxury in the safe house, which is situated off the garden of the main house. They'll be able to watch and listen in on what their fellow housemates say and do, as well as being immune from next week's latest nominations.
Either Gina and Dexter or Dan and Wolfy will enter the safe house o this evening, and plotting pair Gina and Dexter and running away with the lead in our poll.
As it stands, close to 80% of the votes are for the pair to enter ahead of Wolfy and Dan, but while they miss out, they should count themselves lucky.
The twist has saved Wolfy from an almost certain eviction, with the fisherwoman having originally been widely tipped to leave before the safe house was revealed.
