Morganna: not along now my dear we just have to wait for them to reach the ocean…an area far off land where they will be vulnerable…and far enough from your grand father so that my plan will work.
a few hours later morganna and melody headed out into the ocean
meanwhile ariel, eric and cerina were searching for melody and morganna upon the ocean when all of a sudden the sky turned a sickly dark green colour and tides of the ocean became more rougher
when all of a sudden morganna appeared out of the water above a raging whirlpool
and in the sky above green lightening began to strike
ariel: morganna what do you want...and where is my daughter
cerina: and my sister
morganna: shes right here
said morganna as melody leaped out of the water and landed on the ship
her pure black hair covered her face and as she rose from her knees and whipped her hair out of her face she walked up to her new sister and stared at her in the eyes
cerina instantly saw how darkness and evil was in melodys soul but then she saw something else a spark of good and cunningness
melody: so i now have a sister do i huh a 12 year old sister so 2 years with me gone and you replaced me even though you knew i was still alive you...replaced...me...then again wour not to blame you couldn't help it, it was destiny
when melody said this everyone was confused except for her and morganna
morganna: no...don't melody you can't tell them about the prophecy
melody: no morganna i can and will...it is said that when the first siren returns that a sibling will be bourn and as time goes on they will rival each others power and when the final battle arives their will be only 3 possible out comes 1 good wins and the darkness of the siren is destroyed forever 2 darkness wins good is distroyed/joins the darkness and all mermaids from then on will be bourn as sirens or as some call them merdemons and the 3rd is that the truth is revealed and the sibling will join forces to destroy the true enemy.
ariel: melody...this is silly now come home with us
on hearing this melodys anger rose and stamped her foot on the ship and all of a sudden ice with a hint of a sickly green colour rose up and punctured the ship, throwing everyone into shock as water slowly infected the ship causing it to slowly sink
eric: how is this possible are daughter turned to evil...and even more powerful than morganna...how is this all possible
melody: the siren...you are witnessing a mere fraction of it's true power
after saying this melody shot out a net of ice at cerina who cringed as it wrapped it self around her arm and as soon as it did melody dove into the sea taking her sister with her and as soon as melody dived off the edge of the boat her two legs came together to form a red tail, then melody used her power to give her sister a blue tail as she enterd the water.
as soon as they were in the water they headed for the whirlpool of ink along with morganna and her minions and vanished without a trace.
meanwhile ariel and eric were getting dangouresly close to the water when ariel began to glow and her tail returned and as the light hit eric the same thing happened to him, ariel new instantly what was happening she had been exposed to so much magic, from the triton, to ursula, to morganna, to melody that she could now turn from human to mermaid then back again so they both dived into the water and headed to atlantica to warn king triton of what they had learned.
