Katara was not shy about her anger at Zuko, even when he was trying to help them and Aang. Even though it was Firelord Ozai and Azula that were there true enemies he always seemed to be the Undesirable Number One in her mind. He tried to give her space, tried apologizing and even going out of his way to make her happy.

She always sat and watched as he and Aang were training. Zuko knew it was because she was concerned for Aang's safety and for that reason he never let it bother him. As time passed and she grew to trust him and even respect him Katara still came to watch them train. After a few days of this Zuko approached her.

"Why do you still watch us? I thought before you just wanted to make sure Aang was safe," Zuko asked her as he pulled on his shirt.

"At first I was only taking care of Aang, now I just like to watch you when you are in your element. I know how hard you work on your bending and it's impressive. It helps to remind me that fire is not the enemy and can be more than just a weapon."

"Oh, cool," Zuko responded. She chuckled and then tried to hide the blush that crossed her cheeks.

"Do you want to spar?" he asked her. She nodded and watched as he pulled his shirt back off and then got into his stance.

He was good, but she was a master. Everything he threw at her she threw back ten times harder. It was chaos and steam, it was a mixing of elements and it was thrilling. Zuko managed to tackle her to the ground, pinning her shoulders with his hands and her legs he covered with his own.

"I think this means I won," he said without getting off of her. She rolled her eyes but didn't attempt to fight back.

"Umm...I thought you guys were sparring?" Sokka said from somewhere behind them.

Zuko jumped off of Karara and then helped her up. They both blushed and began stammering excuses. After a minute Sokka shrugged and walked off.

"I should make dinner," Katara said as she rushed after Sokka.

They sparred again a few days later and this time Katara ending up pinning Zuko to the ground. "I think this means I won."

He raised an eyebrow at her and breathed a small ball of fire, as a demonstration. Katara rolled her eyes but showed no signs of getting up.

"Look, I'm getting really tired of catching you two straddling each other."

"Sokka! We were sparring and I won," Katara said as her and Zuko got up.

"It wasn't over yet," Zuko shot at her.

"What were you going to do? Fry me with your dragon breath?"

"Whatever the outcome was, I've got my eye on you," Sokka said to Zuko.

The next time Sokka caught them in a compromising state they were not sparring. They had started sparring but when Katara ended up on top of him she kissed him. She felt like they had been dancing around this moment all along, so when she saw his eyes dart to her lips she took her opportunity.

One of his hands was in her hair and the other gripped her waist, keeping her body tight against his. He gave a soft moan when their hips came together and Katara was about to suggest they went somewhere private when something heavy crashed behind them.

They both shot up off of the ground and tried to look casual. Sokka was standing a few feet away his mouth gaping and a pile of firewood at his feet.

"That's my sister!" Sokka yelled as he ran after Zuko.

From Toph's point of view the ensuing chase was hilarious. Zuko and Katara did not find it quite as funny.
