So here is where things gets interesting, hope you guys enjoy it!

Zuko: So I'm guessing I'll be facing challenges?

Yep, read and find out!

...

Darkness. Darkness surrounded him his whole life but now it's different. As Zuko open his eyes all he could see was black. Every time he tries to move his body aches in pain. He see's flashes of faces; all too blurry to make out. The room was always spinning around and out of his control, like his ship during rough seas.
But from the darkness he sees a light; not bright but just enough to see. He forces his legs to move forward and it obeys. As he slowly makes his way to the light his surroundings become clearer; just when he reaches the lights he notices that he's in a steel corridor, taking one last look around he notices that he's still wearing his black clothes and that something about this place strikes up his memories. Looking back toward the light he enters.

...

"How is he doing Kai?" asked Jee.
Kai finish wiping off the sweat on Zuko's forehead before turning around, "Not too good. His fever is escalating."

Jee sat next to Zuko's unconscious body, "Hang in there kid."

...

Zuko eye's adjusted to the light, but that's not the only sense that was adjusting. As his vision became clearer so did his other senses. The sound of waves hitting the metal of the ship and the smell of salt filled the air. Zuko looked around and it suddenly occurs to him where he is.

"I'm on my ship?" he said out loud.

"Of course you are," an unknown voice shouted. Zuko turned around as his eyes widen at the sight before him. Before him stands himself, dressed in his red fire nation armor, bald with his ponytail, and that scar staring right at him. Zuko stood there not knowing what to do.

"Look like you've seen a ghost," his old self said prideful like.

"This isn't happening," Zuko said.

"Oh but it is," said the younger Zuko getting into a fighting stance.

"I don't have time for this," said Zuko.

The younger Zuko smiled, "We've got all the time in the world."

With that he send a giant fire ball right at Zuko.

...

"Jee get in here!" shouted Kai.

"What is it?" Jee shouted as he ran in.

"Look at the flames."

As Jee looks around all the candles are flickering on and off, swaying from side to side, rising and falling with each breath.

"What's going on in his mind?" Jee said.

..

Zuko was able to dodge every single blast that came his way.

'Was I really this predictable?' he thought to himself. He could tell his younger self was starting to get weary. Just then his younger self produced two fire daggers.

"Well haven't seen those in a while."

"Shut up!" yelled his younger self. He came at Zuko with all the fury that he had left but each strike Zuko was able to dodge each one. With each strike Zuko was waiting for the right moment to strike. When he notice his younger self stepped too far to his left, he made his move. He ducked under his opponent's dagger and using his leg kicks a fire arc toward his younger self legs causing him to trip. Zuko stood above his younger self; with the look of anger written all over his young face.

"How?" his younger self asked bitterly. Zuko smiles, "You forgot your basics."

He outstretch his hand toward his younger self offering him some help. His younger self stared at the hand, he slowly reaches out for it, but just as he was about to make contact he slapped the hand away from him. Then he kicked Zuko a few feet away from him. Using his fire creates a fire cyclone; Zuko shields his eyes, ready for the attack; but it never came. When the flame disperse his younger self was gone. Zuko stared at the scorched marks left where his younger self was standing.

"Was I always this arrogant?" he said to himself. He notice that the ship was coming to a slow, he made his way to the bow of the ship to see the outlines of the shore. Noticing the distance closing in; he made his way below deck waiting for them to land. As he felt the ship come to a full stop he waited, waited, and waited. It felt like hours until the ramp finally dropped revealing the sun light and the bare land before him. He made his way out of his ship, when he reached the end of the beach he looks back upon his ship to see the ramp retracted and the ship beginning to go back into the sea. Just as he was about to turn he hears the screeching of metal coming from his ship. He turns back to see his ship slowly sink back to the water grave from wince it came. As tears slowly filled his eyes he turned back and began to walk.
Toward the unknown.

...

Zuko: Okay now that's creepy.

And it's about to get even creeper, so, hope you guys enjoyed it!
