Uma pov

It was just a few months after the birth of uma and Harry's daughter aria and they decided to go sail out to the open ocean to celebrate and so uma's father, king  triton could see his granddaughter for the first time

Uma was currently in Aria's nursery on the boat humming a melody while aria looked up at her  and reached out to uma while laying in her crib

"You are my world, my darling
What a wonderful world I see
You are the song I'm singing
You're my beautiful Aria" I sang as uma picked her up and spun her around and held her close as uma looked out at the ocean

Darling, we better be going Harry sang as he came into the room

Look at her, isn't she glowing? Uma sang holding aria

She looks divine! And you look exquisite! But look at the time! Harry sang

Couldn't be, is it? Uma sang

The crew is awaiting your orders!
We're sailing away from the borders! Andrew sang

Steady, boy, steady!
Ahoy there, they're coming! The guards sang

Trumpeters ready! Drummers start drumming! Andrew sang

Down to the sea we go
Down to a world I know
There's never been, not ever before
A child born of sea and shore

Down to the sea we go
Down to the world below
A journey to bless, a princess to be
Under the sun, and under the sea! The people on the boat sang

Uma is coming, Uma is coming!
Uma is coming, Uma is coming!
Uma is coming, Uma is coming!
Uma is coming, Uma is coming! A fish sang alerting the sea Kingdom of Uma's arrival

"What's all the big commotion
That's spreading through the ocean From sea to shining sea?
There is no hesitating Today we're celebrating Uma's aria!" Sebastian sang "Today when Triton's daughter Comes back here to the water We're gonna have a spree! The boat is nearer now I think I hear her now
Uma's Aria!"

Up from the sea we rise
Up to the world of skies
There's never been, not ever before A child born of sea and shore Up from the sea we rise
Up to the world of skies
Forever to be, together as one
Under the sea and under the sun the merfolk sang

This is your world, my darling
One world, the land and sea
My hope for you, for always
Is that your heart will be part of me uma sang as King Triton rises from the sea and meets his granddaughter

My precious aria...I'm giving you this locket so that you will never forget that part of your heart.. will always belong to the sea. Triton said holding a locket that her Aria's named engraved on it and that projected the Kingdom of Atlantica when you opened it

Suddenly a tentacle came and scratched Aria out of Uma's arms

"Aria!" Uma shouted

A party! The woman said

Ursula's crazy sister! Sebastian said

I didn't miss the cake and ice cream, did I? The woman asked

"Morgana!" Triton said "Surrender the baby, or I'll..."

Ursula would have simply loved to have come...but something came up. Now-Now, what was it?
Oh, yes. You all shish-kebabbed her! One minute you're on top, the next you're sushi. Now, is that fair, gramps? The woman, Morgana said holding aria in her tentacles "But then, whoever said we had to play fair?
Oh, Undertow!"

Make way mershrimp! I'm coming though! Undertow Morgana's shark minion said as he swam through the crowd to the ship where Morgana had aria over the water

Now hand over the trident, or your precious granddaughter... will be shark chow! Morgana said holding aria over undertow's opened mouth

You can have anything you want.
Just don't harm little aria. Triton said willing to handle over her trident for the life of granddaughter

Well, well. I get the trident...avenge poor, unfortunate Ursula...and gain all the powers of the ocean! And it's not even 10 Not a bad morning. Morgana said

Hit the deck! Harry yelled as he cut a rope that caused the main sail to hit Morgana knocking her off the boat but also caused her to let go of aria

Aria! Uma yelled seeing her daughter fall in to the direction of undertow's opened mouth

But aria never came thanks to Triton striking undertow making him small and Harry swinging on the rope catching aria who was giggling and smiling not understanding the danger she was previously in

What have you done to me?
Look at me! I'm an anchovy! Undertow shouted outraged

This isn't the end, Triton!
It's just the beginning! Morgana said 

After her! Triton shouted

You'll never find me, but I'll find you...and your precious granddaughter! Morgana said as she and undertow disappeared in black smoke

We shall not rest until that mad woman is vanquished. Find her!! Find her!! Triton 
said as Lightning is strucked in the sky as an order

Weeks had passed  and Morgana was nowhere to be found. Flounder and Sebastian were with Triton at Harry's and uma's to talk about Morgana's disappearance

I'm sorry. There is no sign of her, she's vanished. We'll keep trying, we'll... Triton said as uma looked worried and aria crawled to the sea babbling

"Sweetie no." Uma said as she picked up aria "Oh, we've got to keep Melody away from her. Until Morgana is found, Melody can't go into the sea.....And neither will I."

But uma... flounder said

"I'm sorry, Flounder. But if Morgana is anything like Ursula, she'll never give up. This is the only way." Uma said painfully  as she takes the locket that Triton had given aria and handed it to her father "aria can't know about Merpeople or Atlantica, or even you, Daddy."

Triton had looked at uma with sadness and defeat as he nodded slowly understanding why she was doing this even if it pained him so

Very well, uma, you're right. Triton said as he watched uma walk back to the castle holding Aria close knowing this was probably the last time he would ever see his daughter or granddaughter again

Sebastian, you will watch over her. Triton said as Sebastian looked at him shocked

Me!?! Sebastian said as he fainted at the thought of having to deal with a mini version of uma
