A relieved Tiffiny welcomed back Michelle, while Lydia reunited with Lisa and the others members of Shannan’s Secret Training Squad. The Bunker was finally revealed to the contestants, who saw their former teammates return on the monitors. In the Weigh-In Room, Hayley explained that over the course of the week there would be five Weigh-In passes up for grabs. Those still in the game, meanwhile, would have Immunity. The past contestants weighed in, with Selena dropping the bombshell that she didn’t want to fight for her place in the game. Both sets of contestants trained their hearts out, before being led into the Contest arena for Shannan’s squad to fight for two Weigh-In passes. For the first round, the contenders had to hold a 1.2kg weight in front of them, without lowering or bending their arms, changing their grip or breaking the tape. Lydia, Bek, Lisa and Simon made it through to the second round on the spin bikes, with Simon and Lisa taking first and second and the passes.
