Episode 4

The Tigers have a mole in their midst, with no one suspecting a thing. Kalia is still feeling unsure about whether Harry's feelings for her are genuine or whether it's all about tactics. The rest of her tribe are starting to get a bit bored of her indecision, but there's no time to brood as they have two new arrivals to impress. And the beach party is full of drama, as after the new arrivals announce their decision, the other islanders are given the chance to swap islands.
