This is an idea I got from reading a fanfiction where Katara writes in a secret diary. Oh and Zuko still has a ship and Iroh isn't a traitor!
Dear Diary,
Hey! My name's Katara. I bought this diary here at the Northern Water Tribe to sort of tell about what I've done and my life, you know so I can read it to my kids when I'm older or something like that. I'm a waterbender from the Southern Water Tribe. Were about to leave the North Pole and thankfully haven't seen that arrogant firebending Prince Zuko yet. I just hope we leave before he finds us again. You see I'm actually traveling with my brother, Sokka and my best friend Aang, the Avatar. Ever since Aang got out of the iceberg Zuko has been hunting him. We always run in with him and somehow always get away. Also we travel on Aang's giant fluffy flying bison called Appa. And how could I forget about his adorable pet lemur, Momo. Well gotta go! Aang just finished packing up!
Love,
Katara
Dear Diary,
We just landed in a forest and Aang and I are practicing waterbending together in a few minutes. I'm Aang's waterbending master now. It's so cool! I'm a master! I'm a master! Still haven't seen Zuko yet! Yes! Well, when we do see him we'll be ready for him! Boy will he be surprised when he sees both Aang and I are master waterbenders! Really looking forward to kicking his butt, again! Gotta go teach Aang how to master waterbending!
Love,
Katara
Dear Diary,
Today I'm going for a walk. I'm sitting by a beautiful blossom tree right by a stream. Nature is so beautiful. I'm getting a little nervous about Zuko though. It's not that we've ran in with him a lot, it's that we haven't. Where is he? Why haven't we seen him yet? Could we have possibly lost him? Normally we would see Zuko at least twice a week, but we haven't seen him since the attack at the North Pole which was a few weeks ago. It's not that I want to see him; it's just if we see him we can get a sense of where he is and it's not a mystery. Maybe waterbending will calm me down. Now I feel much more relaxed and calm. I could do this all… Wait, I think I hear someone, gonna go see who it is. Bye!
Love,
Katara
Dear Diary,
Well it wasn't Aang or Sokka I heard. It was none other than… Zuko. It sorta went like this:
I put you in my parka and turned around.
I called out "Sokka, Aang is that you?"
He walked through the bushes saying "Hello water peasant." and smirking at it.
"I'm not some helpless little girl Zuko." I said a little angry.
"And I didn't come here to play around." he said assuming a firebending stance I hadn't seen in a while. "Where's the Avatar." he hissed instantly becoming angry.
"I won't tell you." I said. "You know me better than that." I said assuming a waterbending stance.
"I guess I'll have to beat the answers out of you." he said smirking. Then we fought. I shot a water whip at him and while he was a little confused I ran into the stream behind me. I started throwing ice disks at him just like I had with Pakku. I kept dicing them out at him but he broke each one smirking each time. "You'll have to do better than that." he said smirking as me stepped into the stream. I assumed my "octopus" stance and sent a tentacle at his leg. But as it wrapped around his ankle, he spun his leg around and it evaporated. "Still not good enough." he said walking closer to me. I stared in shock which quickly changed to anger. I thrashed out a tentacle at his wrist but he easily beat that too and stepped closer, smirking even more. I then sent many tentacles at him wrapping around his arms, wrists, waist and chest. After I wrapped around his entire upper half I turned the many single tentacles into one huge one wrapped around his arms and chest like a rope. Right as I thought I had won he let out one last burst of anger and fire which not only freed him but sent me flying and I hit my head on a sharp rock. I blacked out and when I woke up I was here on Zuko's ship, in a prison cell. I think someone is coming and by the yelling it's probably Zuko.
Love,
Katara
