Nixie is convinced that she and the girls will never be able to return to the pod again and goes off alone to clear her mind. While walking on the pier, she meets a young boy who refuses to go sailing to the South Pacific with his parents. Nixie inadvertently causes the boy to run away after giving the boy advice to "look after yourself". Feeling guilty, she looks for the boy herself and gets him to believe in magic to want to explore the world, also asking him to throw Sirena's carved shell into the South Pacific in hopes it will get to Sirena's sister, Aquata. Meanwhile, after finding a trident through Mako's land entrance, Zac does some research on the trident and ocean mythology and is determined to one day get it himself, unbeknownst to him that the trident's history involves much "horrendous and destructive" power through mermen. Zac is even more drawn to the trident.
