Zuko, Iroh, and I are walking towards the Royal Palace.

"Many times I imagined myself here, at the threshold of the place. But I always thought I would be here as a conquer. Instead, we are the Earth King's personal guests, here to serve him tea. Destiny is a funny thing." Iroh said

"It sure is, Uncle." Zuko said

Before we walked into the room that we were supposed to meet the King in I grabbed Zuko's hand, and pulled him back to me.

"After this, we need to talk." I said

"About what?" Zuko asked

"Now's not the time." I said

"Okay." Zuko said

Zuko kissed my forehead.

"Let's go in." Zuko said

"Okay." I said

Zuko and I headed into the room. Iroh pours some tea into a cup.

"What's taking so long?" Zuko asked

"Maybe the Earth King overslept." Iroh said

I see Dai Li agents enter the room and circle us.

"Something is wrong. The air is hotter." I said in a whisper

"I agree. Something's not right." Zuko said

Azula walks past the Dai Li agents and comes to stand in front of us.

"It's tea time." Azula said

Zuko quickly stands up.

"Azula!" Zuko said

"Have you met the Dai Li? They're earthbenders, but they have a killer instinct that's so firebender. I just love it." Azula said

Iroh picks up his cup of tea, and I crate a distraction for the Dai Li agents. But had yet to put it in action.

"Did I ever tell you how I got the nickname 'the Dragon of the West'?" Iroh asked

"I'm not interested in a lengthy anecdote, Uncle." Azula said

"It's more of a demonstration, really." Iroh said

Iroh begins drinking his tea. Zuko looks over at him and smiles before behind him. Iroh begins breathing fire. The fire blast makes a hole in the wall, I release my distortion which freezes them to the wall. Zuko, Iroh, and escape from the room. We turn around the corner. Iroh generates lighting and destroys the wall in front before jumping down into a bush below. Zuko doesn't jump which causes me to run into his back.

"What are you doing Zuko? Jump!" I said

"Come on! You'll be fine!" Iroh said

"No! I'm tired of running! It's time I faced Azula!" Zuko said

"Zuko. No." I said

"Yes, Kida. She tried to Iroh, and almost killed you." Zuko said

He kissed my forehead, and pushed me out the window. I land in the bush next to Iroh. Zuko looked down at us then turned and head back down the corridor. Iroh grabs my arm and pulls me behind him as we run from the palace.

"Iroh where are we going?" I asked

"To your siblings." Iroh said

It doesn't take us that long to find where they were staying seeing, as there was only one house with a missing sidewall. We also saw a Dai Li agent outside their house so, I quickly used my ice to restrain him. We walk up to the door, Iroh is about to knock when we hear someone talking on the inside.

"There's no one else here." Toph said

"Katara is in trouble. I knew it." Aang said

"Oh, no." Sokka said

"Wait! Someone's at the door." Toph said

Iroh knocks on the door.

"Actually, we know who it is. It's an old friend of ours." Toph said

I hear someone walk up to the door, and open it. I see Aang, Sokka, and Toph.

"Glad to see you're both okay." Toph said

Sokka runs out of the house, and wraps me in his arms.

"Kida. I'm glad to see that you are okay. We didn't know if you were alive or not." Sokka said

"I'm fine, Sokka." I said

Sokka let go, and Iroh and I exchanged looks.

"I…we need your help." Iroh said

Aang and Sook move into fighting stance once they see him. Toph calmly smiles and waves at him.

"You guys know each other?" Aang asked

"I met him in the wood once and knocked him down. Then he gave me and Kida some tea and some very good advice." Toph said

"May I come in?" Iroh asked

Toph nods and Iroh and I walk inside.

"Princess Azula is here in Ba Sing Se." I said

"She must have Katara." Aang said

"She has captured my nephew as well." Iroh said

"The we'll work together to fight Azula, and save Katara and Zuko." Aang said

Sokka walks over to Aang, and points at him.

"Whoa there ! You lost me at 'Zuko'." Sokka said

"I know how you must feel about my nephew." Iroh said

He walks up to Sokka and puts his hand on Sokka's shoulder.

"But believe me when I tell you that there is good inside him." Iroh said

" 'Good inside him' isn't enough! Why don't you come back when it's outside of him too, okay?" Sokka asked

"Sokka, Zuko has saved my life more than once. It's time we repay the favor." I said

"Kida's right. Plus Katara's in trouble. All of Ba Sing Se is in trouble. Working together is out best chance." Aang said

Sokka nods his head in understanding. Iroh moves back to the door.

"Kida and I found someone outside while we were walking up. He might be able to help us." Iroh said

We all walk outside. Sokka, and Aang look shocked. Toph puts her hand up for a high five which I give her.

"Gosh I missed your bending." Toph said

Iroh walks over and takes the gag from his mouth. As soon as the gag is from his mouth he starts talking.

"Azula and Long Feng are plotting a coup! They're going to overthrow the Earth King!" the agent said

"My sister! Where are they keeping Katara…and Zuko?" Sokka asked

"In the Crystal catacombs of Old Ba Sing Se, deep beneath the palace." the agent said

I walk behind the agent and knock him out, then let the ice melt away. The others looked at me.

"Well come on lets go." I said

We quickly head to just outside the palace walls. Toph feels along the ground looks for the Crystal Catacombs.

"Well, what'd you know? There is an ancient city down there. But it's deep." Toph said

Toph makes a tunnel though the ground, beginning to lead to the catacombs. Sokka is thinking up a plan.

"We should split up. Aang, you go with Iroh to look Katara and the angry jerk, no offense." Sokka said

"None taken." Iroh said

"And I'll go with Toph to warn the Earth King of Azula's coup." Sokka said

"Nope, I'm going to go with Aang and Iroh." I said

Sokka went to protest.

"Nope, if they face Azula then they will need my help." I said

Sokka still tried to protest.

"It's not up for discussion." I said

"Fine. But you better come back." Sokka said

"I will." I said

Iroh, Aang, and I walk into the tunnel and down into the Catacombs. Iroh is bending fire for light, and Aang is bending the tunnel deeper towards the catacombs.

"So, Toph thinks you give pretty good advice, and great tea!" Aang said

"If there is anything Iroh loves its making and talking about tea, and giving advice." I said

"The key to both is proper aging. What's on your mind?" Iroh asked

Aang earthbends again before replying.

"Well, I met with this guru who was supposed to help me master the Avatar State and control this great power, but to do it, I had to let go of someone I love. And I just couldn't." Aang said

Aang stops walking making Iroh and I stop.

"Perfection and power are overrated. I think you were very wise to choose happiness and love." Iroh said

"What happen if we can't save anyone and beat Azula? Without the Avatar State, what if I'm not powerful enough?" Aang asked

"I don't know the answer. Sometimes, life is like this dark tunnel. You can't always see the light at the end of the tunnel, but if you just keep moving…" Iroh said

Aang earthbends the rocks away one last time. Iroh's fire blows out. We all smile a little.

"…you will come to a better place." Iroh said

We now are in the Catacombs.

Zuko's Pov:

I'm looking away from Katara.

"I'm sorry I yelled at you before." Katara said

"It doesn't matter." I said

"It's just that for so long now, whenever I would imagine the face of the enemy, it was your face." Katara said

"My face? I see." I said

"No, no, that's-that's not what I mean." Katara said

"It's okay. I used to think this scare marked me. The mark of the banished prince, cursed to chase the Avatar forever. But lately, thanks to your sister I've realized I'm free to determine my own destiny, even if I'll never be free of my mark." I said

"You care about her don't you?" Katara asked

"Yes." I said

"Maybe you could be free of it." Katara said

"What?" I asked

"I have healing abilities." Katara said

"It's a scar, it can't be healed." I said

Katara holds up a white and blue vial.

"This is water from the Spirit Oasis at the North Pole. It has special properties, so I've been saving it for something important. I don't know if it would work, but…" Katara said

Katara puts one hand on my scar, only to be interrupted by Iroh, Ang, and Kida.

On looker's Pov:

"Aang." Katara said

"Kida, and Uncle." Zuko said

Aang and Kida looked surprised at how close Katara and Zuko were standing. But Katara ran up and pulled Aang into a hug. Kida walks over to Zuko, and smack him on the back of the head.

"What were you thinking? She could have killed you." Kida said

"I was tired of running from her." Zuko said

"That is not the point." Kida said

"Aang, I knew you would come." Katara said

"Uncle, I don't understand. What are you doing with the Avatar?" Zuko asked

"Saving you, that's what." Aang said

Zuko takes a step in Aang's direction, but Iroh and Kida both stop him.

"Zuko, it's time we talked. (to Aang and Katara) Go help your other friends. We'll catch up with you." Iroh said

Katara and both look at me.

"We'll find you." Kida said

"If you don't we'll find you." Aang said

Katara and Aang walk away.

"Why, Uncle and Kida?" Zuko asked

"You're not the man you sued to be, Zuko. You are stronger and wiser and freer than you have ever been. And now you have come to the crossroads of your destiny. It's time for you to choose. It's time for you to choose good." Iroh said

Zuko and Kida both scream as crystals grow to encase Iroh. Zuko and Kida both assume fighting position to prepare for the intruders. Azula walks towards us with two Dai Li agents sliding down from the sides of the chamber.

"I expected this kind of treachery from Uncle. But Zuko, Prince Zuko, you're a lot of things, bit you're not a traitor, are you? And Zuko's little friend who sees to be un-killable." Azula said

Zuko steps so he is a little in front of Kida but not enough for Azula take notice.

"Release him immediately." Zuko said

"It's not too late for you, Zuko or your little friend. You can still redeem yourself Zuko." Azula said

"The kind of redemption she offers is not for you." Iroh said

"Why don't you let him decide, Uncle? I need you, Zuko. I've plotted every move of this day, this glorious day in Fire Nation history, and the only way we win this is together. At the end of this day, you will have your honor back. You will have Father's love. You will have everything you want." Azula said

"Zuko, I am begging you. Look into your heart and see what it is that you truly want." Iroh said

"You are free to choose." Azula said

Azula gestures at the two Dai Li agents to leave, who earthbend themselves out. Iroh and Kida look at each other than at Zuko.

"What are you going to do?" Kida asked

"I don't know." Zuko said

"Pick the right choice, pick good." Iroh said

Zuko looked down. Kida knew then what side he picked.

"You promised." Kida said

"Kida I'm…" Zuko started

"Go." Kida said

Zuko just turned and left the chamber. Kida heard Iroh talking but stopped listening.

Where Aang, and Katara are…

A bolt of blue lighting attacks them from behind. Aang stops it using earthbending. They turn around to see Azula, the source of the lighting. Katara uses waterbending to stop another lighting attack. The mist from the vaporized water allows Azula to jumps on to a crystal and firebend two blast of blue fire. Together, Aang and Katara use waterbending to stop the blasts. Azula finishes her jump by landing on a rock pillar. Aang uses earthbending on the pillar, and Azula gasps once she notices the pillar crumbling. She jumps off and lands between Katara and Aang. She points at both of them, preparing to attack.

A fire blast stops her from attacking, and they look to see the source of the fire blast to be Zuko. Zuko looks from Azula to Katara and Aang, choosing who to attack. Aang gasps once he realizes Zuko will attack him and Aang uses airbending to jump away from the blast. Azula starts dueling with Katara, and Zuko throws multiple fire blasts at Aang.

Aang airbends the air currents around him to make a human-shaped gust of air at Zuko, knocking him down. Aang attacks Zuko with more airbending, but Zuko maneuvers around the attacks and gets back up on his feet. He fires more blasts at Aang who is clinging on to a rock pillar. Aang jumps onto a clump of crystals to protect him, but the crystals shatter, sending Aang flying to another clump of crystals. Zuko fires whips to attack Aang once again, but Aang jumps to another patch of crystals and Zuko keeps attacking.

Azula runs away from Katara, who sends a wave of water that cuts her hair. Zuko who is still using his fire whips to attack Aang, who is now jumping along the cave's ceiling. Aang kicks down a stalactite and follows it, using earthbending to increase its impact and sending Zuko flying.

Katara encases herself in water and uses it to stop Azula's firebending attacks. One water tentacle captures Azula's hand another one captures her foot. Zuko frees his sister using firebending to break the tentacles. Azula looks toward the crater Aang had created with the stalactite. Ang crawls out, exhausted. Azula runs toward Aang, Zuko and Katara are now fighting. Katara still has water whips on her hands and Zuko starts using his fire whips.

"I thought you had changed." Katara said

"I have changed." Zuko said

Katara breaths out and sees her breath. Aang, Zuko, and Azula see their breath as well. The water surrounding Katara freezes. A blast of ice and white fire throws Azula and Zuko back. They look to where the blast came from to see Kida who's eyes have an ice blue glow to them..

"Kida." Zuko, Aang, and Katara said

"Zuko's little friend." Azula said

Kida walks over to the now frozen river and waterfall. In one hand Kida holds small fire figures, and in the other ice figures. She throws them in they become full size.

"Attack." Kida said

And they do. They the element warriors do as told. The ice warriors make quick work of the Dai Li agents that were in the chambers. Aang goes back to fighting against Azula, who is also facing off against one of the fire warriors. Zuko is dealing with one of the fire warriors as well as Katara.

"It's time to end this." Aang said

Aang looks at Zuko, then Kida, and finally to Katara.

"I'm sorry, Katara." Aang said

Aang closes his eyes, he turns away from Azula and Zuko and the elemental warriors. He earthbends a crystal tent. Aang starts meditating. Inside Aang's mind a giant version of himself in the Avatar State, the Avatar Spirit, holds an airbending sphere with a normal-sized version of himself in the Avatar State. Back in the crystal shelter, Aang enters the Avatar State and the crystal shelter starts glowing, alerting those outside. Inside the shelter, Aang opens his glowing eyes and breaks the crystal above him. The camera shows Katara looking up to Aang, now rising in to the air, with hope. But before Aang can let Katara go and control the Avatar State, a bolt of lightning strikes him in the back. Aang gets struck, before it zooms out to show her in a lightning summoning position with her fingers smoking. The Avatar Spirit lets go of Aang and falls out of the plane of existence. As Aang falls down, Katara, tears now falling down her face, creates a wave to catch Aang. The wave knocks down the Dai Li agents. She looks down at Aang and back up with tears in her eyes. Zuko and Azula prepare to attack Aang and Katara, but a blast of fire stops them. The entire crystal cavern suddenly becomes covered in ice freezing Azula and Zuko in place. The ice warriors wrap their arms around the firebenders and incase them in it. Iroh suddenly jumps down from the wall of the cave and shields Aang and Katara from Zuko and Azula.

Kida backs up so she is standing next to Aang and Katara. Zuko looks at her.

"Stay Kida." Zuko said

"No, you broke your promise. You promised, and in my eyes. There is no honor in a man who breaks his promise." Kida said

"You've got to get out of here! I'll hold them off as long as I can." Iroh said

Katara and Kida nod and bend their way out of the catacombs. Once Katara and Kida are out of the catacombs with Aang they quickly find Toph, Sokka, who are with Kuei the Earth King, and Bosco his bear. They all climb onto Appa and fly away from the city. Katara uses the water from the vial to heal the wound on his back. The glowing from the spirit water stops, and Katara starts scrying. Aang's tattoos glow for a second and Aang gasps. Katara looks at Aang, who smiles a little, and she pull shim closer. Kida wraps her arms around her midsection, and she starts to cry, but the ice blue glow has yet to leave her eyes.

Meanwhile in the Throne of Ba Sing Se…

Azula is sitting down in the throne with Zuko to her left.

"We've done it, Zuko. It's taken a hundred years, but the Fire Nation has conquered Ba Sing Se." Azula said

"I betrayed Uncle, and Kida." Zuko said

"No, they betrayed you. Zuko, when you return home, Father will welcome you as a war hero." Azula said

"But I don't have the Avatar. What if Father doesn't restore my honor?" Zuko asked

"He doesn't need to, Zuko. Today, you restored your own honor." Azula said

Zuko turns away, uncertain of himself, and with a feeling that even though he regained his honor he lost his heart.
