Will competes in the free-diving championships but afterwards chooses to give up on the sport and shrug off Sophie's influence on his life. Meanwhile, Rikki sees Sophie kissing Zane at the event and breaks off their relationship.

Rikki fears Ryan's explorations on Mako Island will uncover their secrets but Cleo and Bella discount her concern.

Zane resents Will having become part of the team but fails to make the girls doubt his reliability.

Bella suddenly develops a sneezing allergy which triggers her powers. When Zane makes Sophie the head of the café, she looks to use Bella's problem as a way to get her and the band fired.

Rikki is frustrated by the water attacks and goes to Mako Island on a full moon to confront the strange force in the Moon Pool, but Will pursues her while Cleo and Bella are delayed.

Sophie uses Bella's idea for a fundraising concert and presents it as her own to gain publicity for the café, while Cleo is caught in the crossfire with Kim when Samantha moves in.
