The first challenge - dropping water bombs onto a target from a paraglider, doesn't go well as only Alaina gets a hit. Bob, who was betting on the success, does better. Alaina, Bob & Ann-Maree have to take pictures to represent different letters of the alphabet (e.g. B=bridge, a Y shaped track in the road). The letters spell out BETRAY but Crystal-Rose and Marc, who have to guess what it is, don't get it right. The three others also have to tell what Crystal and Marc have painted on a sports oval. While Ann-Maree thinks it is a platypus, Alaina convinces her and Bob it is a mole and they lose money. It was, in fact, a platypus. As the contestants voice their suspicions, they fill out the questionnaire. Both Alaina and Marc are certain it is Crystal-Rose and Bob agrees with them but also thinks Alaina is a good suspect. Ann-Maree suspects Bob (whom Marc has ruled out) and Crystal is torn between Alaina and Marc although she suspects Marc more.
