This week's new arrivals - engineering graduate Jack and promotions girl Della - are immediately impressed by the Tiger camp. But Soodi's decision to move to Tiger Island has upset Hermione and Hollie, who worry that she'll try to control the group.
On Shark Island, tempers flare when Dan isn't happy with how the weekly rations are dished out and Xanthi voices his opinion about the fire, and the arguments continue when Jack and Della arrive. Jack and Della think the 'line of truth' game, which asks the camp to say what they really think of each other, can help, but it pushes the tribe further apart. The Sharks make a desperate attempt to impress Della and Jack with a 'shake it like a Shark' dancing competition.
