Twin of Peril

"Damn it!" Zeero cursed as she was slammed onto her back. Luckily, there was a mat on the ground, though it was really too thin to really help keep from hurting overly much. She was wearing a black karate outfit, tied with an equally black belt. Her feet were bare, but her right hand was wrapped in a black wrap to protect her wrist from breaking should she hit her teacher a bit too hard, though he usually tried to make sure she didn't hit him at all.

"You need to concentrate," Wu Fei told her flatly as he waited for her to get back up. "Clear your mind of those useless emotions." Though he seemed to handle her attempts at fighting him with little trouble, she was quite happy to take note of the light beads of sweat across his brow.

"Sorry," she said, though her tone could easily inform anyone that she was not apologetic in the least. She rolled her shoulders before moving into a fighting stance. She knew she wasn't as graceful a fighter as her sweet sister, but she could handle her own. Besides, street fighting rarely left room for grace. Hard skill, strength and intelligence were what kept her alive on her night time trips no one knew about, especially not Wu Fei.

Wu Fei gave her a polite bow, and she followed suit, never once taking her eyes off her teacher. She almost felt like a different person as she pushed her childish antics aside and prepared to take things seriously. The previous match had been a warm up, but this time she was willing to give it her all. She narrowed her deep blue eyes and her lips tightened into a thin line. She had once heard Quatra tell Trowa that her glare had reminded him of her father, but she had told herself she didn't care. It was her glare and it seemed to shake the clam of anyone she fought. She only prayed the effect was no different for Wu Fei.

Zeero quickly leapt toward her teacher, but instead of punching him, she ducked under his blocking arm and kicked his back with a round house kick. Wu Fei stumbled forward but easily turned to catch the fist that was headed toward his stomach. Zeero smiled wickedly as she brought her knee up to connect with his crotch. Unfortunately, he didn't see too phased by her attack. What? Wasn't he human?

"You don't fight with honor," Wu Fei reprimanded as he twisted her wrist, forcing into a side flip. Zeero made sure her glare hardened so he knew how little she cared. As soon as she hit the ground, she twisted back around to hit him with her opposite hand, her fist connecting with his jaw just as his fist plunged into her stomach. Both fighters stumbled back, but Zeero smiled through her pain. She knew what Wu Fei would call the fight.

"You've done well," the adult admitted as he rubbed his jaw. If she had hit him much harder, she may have broken his jaw. The little girl was getting good.

Zeero beamed with pride as she skipped from the room. She may not have won, but a draw was just as good for her. None of the other students who practiced under Wu Fei could match him. Well, no one other than Harmony, but few knew the two twins trained together when Zeero could convince her pacifistic sister there was no harm in a friendly spar.

Speaking of which, Zeero wondered where her sister had gone. Wu Fei still wanted to teach Harmony a few things that day, and Zeero knew without being told she was supposed to find her. She figured it was an easy enough mission to accept. Harmony only hid so many places when they were at the safe house.

Zeero strolled down a hallway and paused in front of what seemed to be a plain wall. A mischievous smile spread across her face, replacing the stern look that had been there moments before. She had seen her sister sneak through that wall many times before, and knew what lay behind it, an abnormally large hanger that could have housed something as big as a gundam... or five. Zeero wasn't nearly as good at hacking as her sister, but she was good at breaking and entering without getting caught.

"Hi, Zeero!" a sweet and happy voice called as the sound of rapid foot falls approached Zeero. A bouncy young girl around Zeero's age nearly knocked the young twin over when she plowed into in a hug. "Daddy mentioned you were here but this place is so big it's hard to find you sometimes."

"Hi, Layla," Zeero laughed as she hugged the blonde girl right back.Layla was a young war-orphan Quatra had adopted along with Trowa back when Zeero was barely old enough to speak. "I can't hang out. I've got a mission, but I'll talk to you tonight." Zeero didn't bother to explain in further detail and Jenna didn't expect her to.

"Okay,"Layla said happily as she gave Zeero one more hug before dashing back down the hall. Zeero really did like the girl, but missions came before friends.

As Zeero has suspected, Harmony was in her room, but she wasn't alone. She was crying in the arms of a young man with amethysts eyes and dark brown hair.

"Don't cry," Zeero heard him whisper to her sister, his lips brushing against Harmony's ear as he spoke. "It'll be all right. We'll get her back." Zeero almost smiled when she noticed how much he was able to comfort her sister.

The boy, a seventeen year son of Duo named Kyo, had been a crush of Harmony's for years, and Zeero had a high suspicion that he felt the same way. She was glad the two had finally gotten over their shyness and finally done something about their emotions. All good things must come to an end, however.

"Isn't that cute," Zeero teased, bringing the tender moment to an end. She felt a slight flash of guilt, but she did need to send her sister to Wu Fei. All missions must be completed after all. Besides, the annoyed look her sister threw her way made it all worth the trouble.

"What do you want, Zeero?" Harmony demanded, almost spitting Zeero's name like it was a curse. She slid out of her comfortably position and stood to glare at her sister with a look Zeero suspected she usually gave everyone.

"My, my," Zeero said in a lightly teasing voice she only used with her sister. "Did we forget the ass kicking we have to endure everyday?" she asked, referring to their training matches with Wu Fei.

"Ass kick?" Zeero could almost see her sister's mind working in over drive as she struggled to make sense of what she had just said. It didn't take long. "Crap! Wu Fei!"

Zeero watched calmly as her sister darted from the room and rushed toward Wu Fei. Before following like the dutiful twin she was, she paused to glare at Kyo. She like him well enough, but he had to know there would be consequences should he do anything she didn't like. "You hurt her," she said threateningly, "and I'll kill you." She wasn't exaggerating either, and she had a feeling Kyo knew that better than most.

"Be assured," Kyo said softly as she turned to go, "I'd never hurt her intentionally."

"Let's hope so," she said darkly before closing the door behind her. By the time Zeero reached the training hall, she had managed to replace the glare with a sweet smile. She didn't want Harmony to know she had threatened the boy she loved so much.

Harmony was already circling Wu Fei when Zeero finally reached the room. Harmony had such grace it seemed more like she was dancing when she fought. She also had deadly skills that had given Zeero the idea to coin her nickname. Hunter certainly fit the older twin more while she was fighting.

"Are you just going to circle, wolf," Wu Fei taunted as he watched his student. Zeero almost laughed at his foolishness. Harmony didn't fight often, but Zeero could tell she was in this one for the win. Something was bothering her, Zeero realized with a jolt. She was so worried that she almost missed Harmony's attack.

Harmony leapt forward, ready to attack, but Wu Fei easily countered her attempt by sweeping her feet from under her. She didn't stay down long, though. In one fluid roll she returned to her feet and launched back toward her teacher.

To an untrained eye, it would have seemed the two were evenly matched, but Zeero knew both her teacher and her sister all too well. Wu Fei was tired from the fight she had put him through, and Harmony was waiting for an opening. Zeero saw the chance the same time her sister did and nodded with pride when her sister faked a punch. Wu Fei dodged the blow but Harmony had been expecting that. She easily moved with him and kicked him in the face, knocking him backwards with the force of the blow. To finish the fight, Harmony punched Wu Fei across the opposite jaw than Zeero had managed to hit earlier in the day, successfully knocking Wu Fei to the ground. Before the teacher could get back up, she pinned him to the ground and held her hand above his neck, prepared to kill should he argue her victory.

Zeero smirked with pleasure. Her sister may have been a pacifist, but she could kick anyone's ass should the need arise. The look in her sister's eyes quickly took the fire out of Zeero. Harmony was hurting, and not just physically.

Following closely behind her sister as they headed back to their rooms, Zeero scrutinized Harmony's every move. She favored her right, though that didn't surprise her in the least considering how hard she had hit Wu Fei. Zeero even went so far as to follow her sister into the bathroom.

"Hunter?" Zeero asked gently after her sister's inaudible yelp of pain filled her straining ears. "Are you all right?" She wished her sister would just tell her what was wrong, though she doubted Harmony would confess her true pain.

"Yeah," Harmony said, just as Zeero had expected her to. "'Just hurt my hand," she said casually.

"Let me see," Zeero demanded gently, though she wanted to fuss at her sister's secrecy. Harmony was entitled to her own secrets, Zeero knew she had more than enough of her own, but they had always shared the important things with each other.

"Can I take a bath first?" Harmony asked in a slightly annoyed tone.

"Sure," Zeero sighed softly. She figured she would have to wait until her sister felt she could be trusted. She didn't want to wait, but a good fighter knew that patience had to be used at times. Rushing in would get you killed more often than not, and Zeero didn't want her trust with Harmony to be killed.

When Harmony finally got out of the shower, Zeero lead her over to the bed so she could check her sister's hand. Harmony had a tendency to shrug off wounds, while Zeero was willing to put her own bones back into place. It seemed each twin always made the other take care of her wounds when the need arose.

"Why the anger, Harm?" Zeero asked softly as she wrapped her sister's hand. She refused to look up from her work, focusing on the task rather than how her sister reacted to the question that seemed so simple.

"He pissed me off," Harmony said. After a moment she added, "And I'm stressing about Mom and the Preventers."

Zeero nodded in understanding. She figured as much, but there was always something more with Harmony. She would have to be paitnent. "You really did a number on Wu Fei," she said with a laugh when she finished wrapping Harmony's hand.

"I know," Harmony moaned softly. Pacifism, Zeero though, was an annoyance. "I didn't mean to."

"Are you going to be all right?" Zeero asked gently, refuring to her sister's emotional state more than her emotional one.

"Okay," she said as she gently squeezed her sister's shoulder. "Good night, Harm."

"Night, Zeero."

Zeero hugged her sister but pulled away, a glare born of worry on her face when her sister gasped in pain. Harmony seemed to avoid looking Zeero in the eye and that only clued Zeero in on a problem. "Show me," she ordered gently. Harmony sighed as she lifted her shirt to reveal a large bruise over her ribs.

Anger surged through Zeero. She had watched the fight earlier and knew Wu Fei had never gotten in a hit in Harmony's chest. Even so, Zeero had to be sure. Taking a calming breath before she spoke, Zeero sighed, "Hunter? Wu Fie didn't do this. Did he?"

"No," the older twin admitted softly. "This is old."

"How old?" Zeero demanded in a harsh growl. Someone was going to hurt when she found out who had hurt her sister.

"Let it go, Serenity," Harmony snarled defensively as she pulled her shirt back down and got up to stare out the window. Zeero just glared at her sister's back, giving her sister the time she needed. "I got into a fight," she finally said.

Zeero snorted quietly in disbelief. There was more and her sister's actions spoke a thousand words. "What are you not telling me, Harmony?" Zeero asked sadly as she approached her sister. She wanted to make everything all better, but too many stupid people loved to mess with her sister.

"Just leave it, Zeero," Harmony begged.

"I won't leave it alone!" Zeero swore, desperation edging into her usually calm voice. She wanted her sister to trust her. That was all, but Harmony locked everything up so tightly, she forgot how much she was loved by her twin. "You're my sister… It was a guy, wasn't it?"

Harmony continued to stare out the window, never look at Zeero. Perhaps that was what hurt the most. "Answer me, Harmony!" Zeero begged, using anger to hide her tears.

"Let it go, Serenity," Harmony ordered before running from the room, escaping before Zeero could stop her.

"Damn it!" Zeero growled as she set off after her sister. Somehow, she just knew to go to the garden. Harmony loved it so much. However, Zeero found that Harmony was not alone. Once again, she was with Duo's son. With a sad shake of her head, Zeero snuck away, swearing to get the information she needed from Kyo if she had to torture it out of him.
