While helping a girl named Bonnie (Baillie Millar) with some algae, Josh decides to play a joke on her by pushing her into the water. Unfortunately, she gets stung by a jellyfish, and Josh gets Ryan and Eli to help her. Eli overhears Josh ask Ryan about using the antidote and later questions Saksia about it. Having overheard Ryan say that they left it in the cart, Eli tricks Natasha into bringing the cart (which had been abandoned a short distance from the camp) back to camp. While Eli, Natasha, Lily, and Ryan head out to find the cart, Josh and Em unsuccessfully try to cheer up Bonnie. When Ryan and Eli find the cart, Ryan tells Eli that the antidote is gone, but he has actually just hidden it. Eli, Saksia and Bonnie then pretend that Bonnie has gone into shock and cure her with an antidote of their own. Ryan falls for the act and believes they no longer need the antidote. With Ryan's guard down, Eli steals the antidote.
