While the girls are under the spell of the moon, the girls blow him out of the moon pool cave through the crater and the next day they find him horrified in the jungle of Mako, not knowing about their upgraded powers. Rikki finds out about this when she creates lightning to dry clothes and sets it on fire. Cleo accidentally blows a strong wind towards her sister when Cleo's sister annoys Cleo. Emma accidentally freezes the whole kitchen when her brother leaves the freezer door open and she tries to freeze it. The girls lose their controll over their powers.

At Mako at the moon pool, they meet. Zane promises to Rikki that he can handle her secret and restores his relationship with her.
Lewis contacts Max Hamilton, an old friend of Louise who did do research to Mako as well when Louise was a mermaid. At first Max tries to avoid Lewis. However Lewis convinces Max to give him the research Max did on Mako. Lewis only has to take Max to Mako. After some doubts, Lewis agrees. However, at arrival on Mako, Max rushes to the land entrance of the moon pool and enters the cave. There he meets Cleo in human form. He splashes her wet, finding out about her secret. Max says he had to know for sure and appologizes to Cleo and comforts her not to be scared. He then tells his story to Cleo and Lewis and gives his research to Lewis.
However Charlotte finds out about this research when she sees a picture of her grandmother in Cleo's bedroom. She takes te research to Max and forces him to talk. He will not talk to her, untill she tells him that Gracie was her grandmother. Charlotte also finds some drawings of Mako which are a map towards the land entrance of the moon pool. Charlotte decides to check out and finds the moon pool. She also finds out about Cleo, Emma and Rikki being mermaids. After being scared away by the mermaids, Charlotte returns to the moon pool, waiting for something. As she decides to leave because it's late, the moon pool starts bubbling and Charlotte jumps in and becomes a mermaid.
Cleo finds out about Charlotte when she comes across Charlotte during a swim. Lewis already has told Rikki and Emma when Cleo wants to tell what she saw. Charlotte already showed her tail to Lewis earlier that day. The girls try to help Charlotte find her power. She has some difficulties with it but eventually finds her first power, the same one as Cleo. Eventually at a volleyball competition, Charlotte gets wet and discovers that she can use heat to dry herself, the same one as Rikki's power. After the volleyball competition the girls go to the café and Rikki asks to Charlotte how she dried off so quickly. Charlotte shows her heating power, and as well admits that she has Emma's power too and shows this to the girls. The girls are shocked.
Throughout season 2, Charlotte keeps training her powers and eventually decides that she's the strongest mermaid and doesn't need help from Emma, Rikki and Cleo. Charlotte also believes that her powers are what's rightfully hers, because her grandmother was a mermaid.
Charlotte eventually becomes an enemy of Rikki, Emma and Cleo. She taunts Cleo which leads to a fight between the two. Charlotte wins, humiliates Cleo and steals Cleo's necklass. Charlotte believes that because it was her grandmothers necklass, it doesn't belong to Cleo but to Charlotte. Charlotte lies to Lewis that Cleo kindly gave her necklass to Charlotte. When Cleo sees this, she gets very sad and runs away. Charlotte also stole Lewis's phone so he can't hear any incoming calls from Cleo. Cleo tries to call Lewis and speaks in his voicemail. She then runs away. Cleo's father finds out about that Cleo's missing and calls Rikki and Emma for help. They contact Lewis to tell him what is going on with Cleo. Lewis also finds out that Charlotte stole his phone. He hears the voicemail that Cleo spoke in and is so worried that he breaks up with Charlotte, as well because she stole his phone. Lewis asks Max where Cleo could be. He gives a possible location, a shark breeding ground around Mako. Lewis gets some ace from Max to lure away any sharks in the area where he's going. At arrival, Lewis dumps the ace and dives into the water to find Cleo. He sees her as she's afraid of all the sharks in the area. He gains enough trust from Cleo and rescues her. At the beach of Mako, Lewis restores his relationship with Cleo and brings her back to home, where her father was almost about to call the police for giving more details about Cleo, such as pictures. Everyone is very happy to see her. However Charlotte is furious and swears war on Cleo and her friends. Charlotte also at some point uses her powers on the girls because she's angry, lifting them up in the air and letting them fall onto the ground, leaving the girls with bruises.
The next moon is a dangerous one. Louise visits the girls and Lewis to warn the girls and Lewis. The upcoming full moon is so strong according to Louise that it can actually take away a mermaid her powers forever. So the girls are warned to stay away from Mako during that full moon. The girls also warn Charlotte. But she doesn't care about the warnings. Charlotte even uses the power of this moon. She gets affected by the moon during this dangerous moon and turns everything upside down in Emma's house. Lewis is able to send her towards Mako. Cleo decides to go to Mako as well. However Charlotte has planned this. She holds Cleo captive into the moon pool by aiming her powers at Cleo. However Lewis distracts Charlotte and she loses sight of Cleo. A fog appears and Rikki, Emma and Cleo appear in human form as they step out of the fog. A fight starts. Charlotte creates a three-headed serpent, with which she threatens the girls. As the moon makes the pool bubbling, Charlotte chooses Cleo to jump into the water at first ti lose her powers. However, the girls are not planning to jump into the moon pool, and they decide to use their powers in the way they did before when they lost controll. It now is mermaid power vs mermaid power, and Charlotte loses. The girls lift up Charlotte in the air and dump her into the moon pool as it is bubbling, making her lose her powers forever.
The next day she appologises to Lewis and the girls and realizes that these powers were never ever meant for her to have. She promises to keep the secret and she's never ever heard from again.
