A/N: And I'm back!
I am, as some of you might know a big Overwatch (lore) fan, and, as fewer might know, a fan of the Webcomic SubZero (READ IT, I BEG YOU), both of which include characters with special bond with dragons. And ninjas.
Anyways, what I'm trying to say is: I let myself be inspired a little by both for some of the dragon stuff here.
Notes: I also apologize for any past, present, or future OOCness.
Also, this one definitely goes more in the crack/humour direction.
Disclaimer: I do not own.

Katara officially hated going home alone. Usually, when she went shopping, one of the others would go with her, to help her carry, but somehow, everybody had been busy, or in Sokka and Zuko's case, injured (the shit they managed to pull when sparring was unbelievable). She had been ambushed by her unknown captor, who snatched her from behind when she'd been on her way from the market to Zuko's beach house earlier that day, before knocking her out. She just had woken up here, in a dark and gloomy cave, with her hands tied behind her back by her wrists and her feet by her ankles. She tried to push herself upwards, but was hindered by her restricted arm movement. Trying to get more comfortable by flopping over was apparently, her only option.

Suddenly, she heard an almost guttural roar from the direction of the cave entrance, then - people shrieking in pain, a sizzling sound. Little rocks clattering across the stone floors and breaking off walls. Something very, very big pushing it's way through a very narrow hallway (or something like that), all the time sounding closer and closer by the second.
Had her situation been half as bleak - in the no way out of both captivity and boredom-way; and Katara half as "done with that shit(TM)" as she was, she would have maybe been scared of whatever was making it's way towards her. Instead, she just boredly flopped around so she was facing the entrance and put on her best "Whatever" face, just in time for- a dragon. A big, scaly, red dragon with a comet-shaped scar over its (his) eye.
Could it be...?

"Zuko? Is that you?" she asked the beast, quietly, almost timidly. The dragon blinked its big amber eyes at her very slowly and very sarcastically - she hadn't even known it was possible to blink sarcastically - as if to say "Yes, dumbass, now don't stare and move."
Katara sighed.

"I guess so, then. Could you maybe help me out here, though?"

She leant back on her elbows and wriggled her legs around. The dragon - Zuko - shrank together. Literally. It grew smaller and smaller, becoming more and more human as it did. In the end, Zuko was standing in front of her, in all his human glory - including his slight limp from his first injury, and a deep gash across his chest - with his swords pointed towards the ceiling.
Before she could even blink, the ex-prince had uncut all of her bonds.
Rubbing her wrists, she thanked him. With a hug. He almost fell into her when she wrapped her arms around him. Still, he replied, "Don't mention it."

Katara did not like that one bit. Even less when he released her and started making his way out of the cave.

"Listen here, Zuko," she told him as they crept through passages and crevices, caves small and large, "don't say 'Don't mention it' right after almost toppling over. You clearly exerted yourself to save me. And I am very thankful for that, but I would be even more thankful if you just relaxed a little. Let's just sit down here, and give you a chance to sleep. You can tell me why you randomly became a dragon."

He turned and looked at her. She stared back, putting all her determination into her gaze.
He sighed and plopped down onto the ground, barely even wincing as he landed wrongly on his injured leg.

"Fine."

She sat down by his side, and smiled at him.

"Good."
