To answer somebody's question: Aang and Toph are 14, Katara is 16, and Sokka & Zuko are both 17. Everyone else will be as old as they are in the show.

Aang suddenly stopped walking.

"What's that?" he asked me, pointing at a large building. I froze.

"That is a Firewares factory," I explained. "No one's been in there since my Gran-Gran was a little girl. It does nothing but serve as a horrible memory of how my family's business went crashing down."

"Maybe we should go in there…" Aang suggested, as he took a step closer.

"No. It could be dangerous."

"It's okay. Just be brave, Katara, nothing will go wrong."

Reluctantly, I walked into the old factory with Aang. The walls were dusty and moldy, and there were cracks on the ceiling.

"Aang, I think we should get—"

Suddenly, there was a loud CLANG sound, and I realized the factory doors had been sealed shut.

There was no way out.

Sokka's PoV

I heard Katara say that she would be going outside with Aang to show him around, I still didn't trust the guy but I trusted Katara and I knew she could use her better judgement.

It was dinnertime. They went out at like 4 and they're still not back. I wonder what's taking so long?

My thoughts were interrupted by the ring of the doorbell.

I got up from the couch, and opened up the door. I saw someone that I didn't want to see.

"Zuko? What are you doing here?"

"I know he's here? Where is the Avatar?"

"Avatar Inc.'s been dead for years, Zuko! I don't know what you're talking about!"

"You know, that new kid!"

Aang! I thought to myself. I knew he was fishy!

"He's not here, leave us alone."

"Don't you dare lie to me," Zuko growled. Then he grabbed me and threw me across the room.

What's taking Katara so long?

Katara's PoV

"Ugh!"

"Don't worry, Katara, I'll figure something out." Aang pondered for a moment. Then he jumped up. "I got it!"

Aang took a bar of metal lying on the ground and shattered a window. Then he picked up one of the shards and carefully cut the door open.

"Quick, let's go!" he grabbed my arm then dragged me out.

When we got back to my apartment Sokka and Gran-Gran were both standing at the door looking at me with disappointment in their eyes.

"Katara," Gran-Gran sighed. "You've put us all into danger with this boy here. I'm afraid he can no longer live with us."

"But Gran-Gran, he—"

"No!" Sokka yelled. "He's officially not welcome."

I snapped. "Then I'm not welcome either! Come on Aang, let's go."

"Katara! Would you really choose this boy over your own family?"

I was about to leave but then what he said hit me like a ton of bricks. I liked Aang, but I loved my family. They would always be number one.

"I…I guess not. I'm sorry Aang…" a tear rolled down my cheek.

"It's ok, Katara. I'll find my path. See you at school tomorrow…"

Then he walked out.
