The sun had finally set. The moon had finally taken up its spot in the dark sky. The brisk breeze chilled Ty Lee as she tip-toed beside her partner through the trees. The Avatar led the way to the secret building holding captive of the harmful fluids. Neither of the agents made a sound. They were both cloaked in a black uniform, tailored to their specific tastes.

"We're getting closer," Aang's voice was barely audible.

He pushed past a branch and a bush and revealed a large clearing in the middle of the forest. A two story building stood in the center. It was surrounded by fences and a guard posted every few feet. Candles hooked onto the walls lit up the area, giving it an eerie and forbidden aura.

"What's the plan?" Ty Lee questioned in a hushed whisper.

"Take out the guards, sneak inside the building, grab the vile, get out without getting caught?" he suggested almost jokingly.

"Simple and sweet. Me likies," she replied, grinning. "No wonder you're so good at coming out alive! There isn't an fussy details in your plans!"

"That's how I roll," Aang replied, laughter clearly bubbling in his voice. "Let's go!" The airbender opened his glider and flew into the sky, disappearing in just seconds. The acrobat cart wheeled her way to the fence.

She suspected the fence was charged with electric attacks of some kind. Time to get my flirt on. She straightend out her matching skirt and shirt, exposing her curvy body.

"Hey! You there!" a voice called. A man stalked out the shadows. "Stay where you are."

"I'm not going anywhere," Ty Lee replied, batting her eye lashes seductively.

The man stood right in front of her on the opposite side of the fence. He wore a grimace on his square face. "What are you doing here?"

"What am I doing here?" she laughed. "The question is, what are you still doing behind this fence?"

The man was unfazed and gave the girl a blank stare.

Time to change my approach. "Okay, okay. I see you're a smart guy--a strong smart guy. So let's cut to the chase," Ty Lee started. "I was just minding my own business on my expensive yacht, and this freak tsunami hit it! It was terrible! I was caught in the wind and I ended up here! When I woke up, I was bonked on the head with a coconut and all I remember was this story! Can you please direct me to the nearest comfortable bed?"

Again, the man shot her a blank stare. She hoped he would buy her fake story. After a while, his expression softened.

"Well, why din't you say somethin'?" he said. "We gots the comfiest beds 'round. Hey, guys, open the gates! We got a li'l lady in need of good night's rest."

Almost immediately, the fence opened up and Ty Lee walked in. The man directed her down a path, where a group of men stood. It looked like the every guard on duty was waiting for her. The whole lot of them drooled all over her--who couldn't?

"Sorry, boys," she greeted them foxily. "I'm taken." Her arms and legs whipped out lightning fast, hitting one man's pressure points after another. Her fists were a blur in the night has each man fell to the floor with a light thump. She stood triumphantly, her hands on her hips, smirking.

"You're doing a fine job! Keep up the good work!" Ty Lee waltzed into the entry of the building and held the door open for her partner, who had just landed.

"Wow, you're better than I thought you'd be!" Aang congratulated.

"Thanks!"

"Let's get back to business," the Avatar said. "Divide and conquer." He pointed down one corridor, and he headed down another.

Katara and The Duke maneuvered their way through the thick forest. The waterbender took up the front as the young boy took up the rear. He turned around every few seconds, as if to make sure no one was following them. Katara had brought her water skin that hung across her back and The Duke had a bag of oddly shaped objects and a club of some sort.

At last they came to the back of the building. Katara expected nothing less than an electrical fence—of course, she was prepare.

"Where are all the humungous guard people?" The Duke questioned, tailing behind the older girl.

Katara scanned the building, finding that the guards were huddled around the main entrance, leaving the back open. Fools.

She instructed her partner to stand close to the fence, while she positioned herself a ways back, popping open the water skin. She sprinted closer and closer, pulling out a blob of water. It stretched into a long stream, slipping under The Duke, and taking him over the building's defensives. He tumbled across the grounds gracefully. Then picked himself up, grinning.

"Great job!" Katara gave him a thumbs up. "Now, open the fence."

It took only a moment for the boy to find the switch that would open up the gate. He pushed it and the gate swung open, creaking only in the slightest. Katara hurried inside and signaled for The Duke to close the entrance.

The back door was easy to pick open. The Duke swiped out a needle from his bag and wiggled it into the lock. In seconds, they were inside, clicking the door shut.

"Okay, follow right behind me," Katara ordered. "Divided we fall."

The scurried down the hall, bonking out each and every security guard they ran into before he could call out for reinforcements. They were dragged into a janitor's closet and duo moved onward.

"Where exactly are we going?" The Duke inquired. They had been running around the building for at least a half hour, and hadn't even glanced at the secret bottle of fluids.

"To the center of the building, underground," Katara explained, back to the wall, sliding ever so quietly. "A deadly vile of this destruction would be kept where no one can get it…" She stopped when she heard a small sound coming from behind them. She turned her head, and heard the sound again.

"I think there's someone following us," she whispered. "Go check it out."

He obeyed, crouching like a tiger-bear. He rounded the corner, and disappeared from her sight. Katara advanced further up the hallway, thinking her partner would catch up unarmed.

She was so focus on being quiet she didn't hear take note of other suspicious sounds. Katara turned a corner, bumping into someone. Reacting on instinct, she whipped out a blade of ice.

Before her stood a boy about her age, dressed head to toe in a black outfit she had only seen in scrolls. He stood tall and confident, he didn't even blink. The tattoo imprinted on his body explained why.

"Who are you?" Katara questioned, even though she already knew the answer. She readied herself for whatever outcome was prepared for her.

"Who are you?" he shot back. A ball of fire bounced to life in his palm. Even though Aang knew exactly who she was, he still asked. He had heard about her. She was enrolled at his rival secret agency. They never met before, but he knew she could kick butt like no other.

Just after a minute surpassed, Katara made the first move. She swung about the ice blade that had morphed into a water whip. It lashed out at Aang in flurry of splashes. He attacked with his ball of fire turning into balls of fire. They launched out into the water, steam rising in the hall. She brought out two ropes of water, wrapping them around her opponent giving him no time to think. She was about to leave a scar on his body, when the handcuffs backfired onto her. They curled around her frame in a tight embrace.

Katara struggled to break free of her prison. She cut the whip many time, but it was tied and it didn't look like it was going to be undone any time soon. She shot her best glare at him, while he smirked, as if he already won.

Out of nowhere, a pine cone flew through the air, knocking the Avatar to the floor and releasing Katara. The attacks of nature items continued to bombard the enemy. She whipped her head around to find The Duke pulling out bombs from his pouch like there was no tomorrow. She smiled gratefully. She was bending a long river of water in Aang's direction, but a shout stopped her.

"Katara, watch out!" her partner warned. "Don't let her touch you!"

A girl dressed the same as the Avatar popped in front of her, smiling. Her arms poked out like thorns. She was aiming for Katara's legs and shoulders. The river of water streamed into the new opponent, sending her to the wall. She was drenched. The waterbender grinned, looking back at The Duke, who was having a little trouble of his own.

"Get away, arrow man!" the small boy yelled. "Or feel the wrath of my sand!"

Aang couldn't help but laugh. This little guy was interesting, not to mention hilarious. He kept shooting rocks at him as he stepped out of the way easily avoiding the attack.

"Oh, you asked for it!" The Duke, latched his bag onto his belt, and snatched his club from his back. He leaped onto the wall, and pushed his feet off for speed. He swiped the weapon in the air, flipping in the process, almost conking the Avatar out. Aang ducked down just in time, but was surprised by buckets of water being poured on top of him, and then freezing him in to the ground.

The young buy and waterbender stood side be side, the smaller one leaning on the taller. They made a perfect team. Aang couldn't help but wonder if he were her partner… His thoughts strayed to her lush chocolate brown hair, her beautiful smile, her mesmerizing eyes… Whoa, when did this happen? He shook his head as if to remove his previous train of thought.

Out of the corner of his eye, he saw Ty Lee flipped into a fighting stance. Their enemies shot her an are-you-kidding-me kind of look. Aang had to admit, these guys were good.

"Did y'all hear all them noises? I think it's comin' from over 'ere," a voice said from round the corner.

Katara and The Duke were already out of sight as Aang was just unfreezing himself. He peaked one last look at her and forced his mind to focus on the task at hand. He gave Ty Lee a nod. A group of men entered the corridor, shock and panic painted across their faces. They all pulled out a sword, hands shaking.

The duo was out of the building, one bouncing through the tree, the other's befuddled mind racing.
