That night, Sina gave birth to two little girls, twins, Sina was tired from giving birth and eventually fell asleep. Chief Tui, Sina's husband, chief of Motunui, came in the house and went to see her two daughters. But as soon as he looked at his other daughter, he panicked.
She is half human, and half...fish. His mother is the one who helped Sina gave birth and she is shocked as well. But that didn't stop her from loving these treasures. After all, she loves the water and all the creatures in it. But Tui thinks differently. He remembers that day that his best friend died.
And with that, he asks his mother, Tala, to take care of the other one and that nobody should ever know that she is alive. Tala wants to disagree, but she thinks of what they might do to her grandchild. So she simply nods and holds the little one.
He looks at the normal baby girl and smiles, "I'll call you, Moana." The baby girl laughed at him and this made him tear up with joy. He then looks at the other one that her mother carries and smiles, "and she shall be called Alania."
The baby girl looks at him and smiled. He didn't noticed that his wife is crying with joy and asks to held the both of them in her arms. Tala and Tui gave them to her and she hugged the both of them.
Alania sleeps peacefully while Moana looks at her sister and giggles. Tui and Sina smiled, but suddenly disappears, for they can rarely see their little Alania. And they've also decided for the best, to not tell Moana about her twin sister.
"That's right dear, now, swim along. I won't be long, Alania," said Tala. Alania swims happily near the shores of the island. She goes around to find new shells to gather. Tala goes off to tell some stories to the other children, including Moana.
Both Moana and Alania looked exactly alike, except, Alania has more lighter complexion than Moana. Tala always told tales about the great Maui, demigod of the wind and sea. Who stole the heart of Ta Fiti and disappeared. Everyone fears of going through the ocean, exploring beyond the lagoon. Everyone, but Moana.
She's more interested to the life out in the waters and wants to know more from her grandma. Tui heard the children cry and came in to check on them. When he said that there's no such thing as monsters, he accidentally hit the rope and the pictures of monsters unrolled. The children cried more and rambled. Moana got out of the rampage and giggled.
Then, she heard something from outside the hut. With her curiosity, she goes outside and sees the view of the lagoon. She happily goes near without her father noticing. But Tala knew exactly where she went. She kept an eye on Moana.
While Alania searches for more shells, she sees another girl by the shore, she hid her body in the waters and watches as the girl goes near the waters. A shell floated to the girl and she was almost going to grab it until she saw a little turtle behind the leaves. It can't walk right to the lagoon without the crows picking on him.
So she did the right thing to help the baby turtle to the lagoon. It swam and went to its mother. But it sees it's friend and swims to her. Alania slightly hugged her friend. The turtle always had trouble going out the waters, sometimes Tala helps it. It swam to its mother and Alania turned back to look at the girl.
The water separated and showed her more shells, which turns out, Alania's collection of shells. The water played with her and Alania just stared. Then, something floated up to her. A green glowing stone, but it's only a half. Alania now wants to get a closer look, she swam to where the water separated, and the girl saw her. Their hands almost touched when a man came looking for her.
The water carried Moana back and it pulled Alania to where Tala is.
