Pretending to be interested in safe-guarding the trident from Zac, Cam offers to help Nixie move it to a secure location.

Zac has a nightmare involving the trident and the Moon Pool. Cam apologizes to him and expresses his disappointment in Zac's locking it back up. Zac almost tells Evie his secret. Cam approaches Nixie with a bogus story and a plan for the two of them to "put the trident out of Zac's reach." Evie tags along with Cam to Mako Island. Nixie, displeased by Evie's being there, opens the cave with a stolen Moon Ring so Cam and Evie may go in. The two enter the water chamber and Cam takes a hold of the trident. With the Moon Ring losing its power, Cam makes it out, leaving Evie trapped inside and losing air. Carly informs Zac, Lyla, and Sirena that she saw Cam and Evie headed for Mako. Will they make it in time to save Evie and what will become of the trident, now in Cam's hands? Will Evie become a mermaid or will Cam become one?—grrlpunk

Pretending to be interested in safe-guarding the trident from Zac, Cam offers to help Nixie move it to a secure location. Cam borrows diving gear from Evie but, intent on discovering the cause of Zac's strange behaviour, she insists on going to Mako Island with him. On Mako, Nixie refuses to work with Evie but relents and opens the cave in front of her using one of Rita's Moon Rings. Inside the cave, Cam opens the portal and he and Evie enter the water chamber. Cam retrieves the trident but with Nixie's ring losing power, she cannot hold the doorway open and Evie does not make it out in time. With Evie's air running out, Nixie rushes off to get another ring only to encounter Zac, Lyla and Sirena who have arrived on Mako Island after discovering what Cam and Nixie are up. Sirena is able to use her Moon Ring to reopen the portal allowing Zac to rescue Evie. As Zac and the girls are confessing everything to Evie, Cam speeds away from Mako Island with the trident.
