“A New Tail”
Season 1, Episode 4
February 13, 2015
Erik's curiosity about the girls and Mako Island becomes a problem when he decides to investigate further.
Zac decides he wants to show Evie "the good side" of having a tail. Eventually she agrees to go for a swim with him. Erik's interest in Ondina continues to grow. He delivers a seafood order to Rita's house and uses this opportunity to talk to Ondina. While out for a walk with Erik, Ondina is accidentally sprayed and turns into a mermaid in front of him. Distraught and despondent over having her secret blown, she tearfully admits what had happened to Zac and Evie, who inform the others. Mimmi convinces Ondina to try to tell Erik to keep quiet about what he saw. When she does, he not only promises to keep her secret, but reveals that he is a merman and that his kind live primarily on land and travel frequently to keep their secret. The others are worried given the history of mermaids and merman, but Ondina expresses trust and possible interest in Erik.
