And here is where the creeper comes in!

Zuko:... I don't like this.

...

Jee stood there looking at Zuko's still body. The flames surrounding him started to calm down, moving with each breath he takes. Jee just stands by the widow, feeling helpless not being able to do anything about what is happening to the young man.

"Wonder what he's thinking now?"

...

Zuko walked for what felt like hours; deeper into the unknown wasteland. Walking at a slow pace he look up to see the sky, he also notice that the sun didn't move at all since he left the ship. Zuko was starting to feel the effects of his last fight starting to kick in as he kept walking. Every muscle in his body was crying in pain, he wanted nothing more than to lay down and fall asleep; but a voice in the back of his head tells him.

"Get out of there."

He tried to comply with the voice but the darkness is slowly closing in on him. Just as he was about to give in, he notice what looked like a village in the horizon.

"Thank Agni," he said to himself as he picked up his speed toward the village. Upon entering he notice the state that the village was in, most of the building were burned, also upon the wreckage was bodies that were burned beyond recognition. The smell of burning flesh still linger in the air. A smell all too familiar with Zuko. His eyes widened when he came to what would have been the town's center when he sees the remains of the watch tower.

"I'm in the village," he said to himself. As he went over to the remains of the tower he couldn't help but feel sick about the way the village was attacked and how he couldn't do anything about it. He turned around and started to head for Kai's home. When he got there, there was no one in sight. With disappointment written all over his face he headed back for the town center. As he reached the center he began to make his way out of town when it hit him. He looked all around and all the buildings were fixed, even the burnt bodies were gone. His eyes couldn't believe it.

"Okay this is starting to get weird," he told himself. Just then a chill ran up his spine.

'Not again,' he thought to himself as he turned around to face the newly constructed watchtower and upon the watchtower he looked up and saw in horror.
He saw lone figure on the roof of the watch tower; with the sun at his back causing him to look like a silhouette against the bright sun. He looked at the figure with his arms crossed and saw through the brightness his demonic mask. His eyes widen at the sight of the grinning blue mask.

"You!" Zuko shouted at the Blue Spirit. The Spirit nodded and jumped down from the watchtower, rolling when he hit the ground and close the space between them, standing a good ten feet from each other.

"I don't have time for this," Zuko said. He brought up his fist to blast him but nothing happened. He punched his hand out again but nothing happen.

"You got to be kidding me." The Spirit drew his swords and got into a stance. Zuko stood there, "Wish I had my swords," he thought to himself. He then felt something being fasten to his back. When he turned his head over he saw the hilts of his swords.

"Well that was convenient," he said as he drew his swords.
They both stood there, with their swords drawn ready for the other to make the first move. Zuko decided he's waited long enough; he closed the distance and slashed his swords to both sides. The Spirit used his swords to block. The sound of metal on metal echoed for miles.

...

"Jee! It's happening again!" yelled the cook. Jee ran in to see the fire dancing wild across the room as before. Jee went to Zuko side again, "Agni, what the hell is going on in there?"

...

No matter what Zuko did the Spirit seem to keep up with him on par. Every slash he made his counterpart was able to block it with ease and vice versa. Many times when they were fighting Zuko tried to use his fire to get an edge on his opponent but each attempt failed, giving his counterpart and opening each time but Zuko quickly blocked each move. Zuko then brought his left blade and sliced across his opponent's right arm causing him to drop his sword. The Spirit took a step back switching his left sword to his right hand as he used his now free left one to grab the wound upon his right arm. Then the Spirit tore off the fabric surrounding his wound, revealing his bare flesh. Zuko saw scars running all along the arm.

"What the hell?" he thought to himself. The Spirit picked up the fallen sword and resumed his stance.

"Okay new plan," he thought to himself. So he tried a new strategy, he swung both his swords at the same time with more force than were necessary. When their blades collided Zuko pushed them all to the side, when they separated Zuko spun around bring up his foot and collided with The Spirits mask. The force was enough to rip the mask from his face and landed a few feet away.Zuko look to The Spirit who had his back turned. As he turned around Zuko's eyes widen at the face beneath the mask. It was his face, yet not his face. His scar was still there, but not only that his entire face was filled with scars.

'And I thought I looked bad after my ship exploded,' he thought to himself.

"What happened to you?" Zuko asked him. His other self-looked right into his eyes before answering.

"Not all scars are seen."

His other self-took his stance, ready for another attack. Zuko complied with his wishes. And once more they were at it again, steel on steel. But this time was different. Zuko couldn't stop looking at all the scars he had across his face. But after a few moments Zuko decided that this was enough. With what strength he had left he knocked his other self's blades from his hands and knocked him on the ground.
Zuko stood above him with his swords crossed around his other self's throat.

"Yield," he said to his fallen self. His fallen self-nodded, Zuko seethed his swords and offer his hand to his fallen self. His other self-took the hand and was helped up.

"Now I'm only going to ask you this one time," he said, "Where the hell am I?" Zuko asked. His other self-shook his head, "That is not my place to tell you."

His other self-looked to his right to find his mask a few feet away, he raised his hand and after a short second the mask flew back to him. After grabbing it midair he tied the mask back on, he turn to face Zuko.

"Follow the light to the door. Once you're through find the master, he'll tell you where to go from there."

Before Zuko could ask his other self-turned into smoke before his eyes and was carried away by the wind. Next thing Zuko knew it was nighttime, it was pitch black. Zuko raised his hand and produce a flame.

"Oh now you work," he said to himself. He then notice that his flame was pointing to the west. He turned to his right and notice it was still pointing the way it was before.

"Well I guess he said follow the light."

So he turned around and started to head in the direction his flame was guiding him to. After a short while he came to the home of Sela and Lee. There he stood before the entrance to the home.

"Well might as well get this over with," he said to himself. He open the door to find a blinding white light illuminating from it. He took a deep breath and he steeped in. To his next challenge.
...

That was some pretty bad scars your present self had, must've been really bad.

Zuko:... So I'm guessing the next chapter I'll be facing my future self?

Wait and see Zuko, wait and see.
