Sorry my Yullen fans ^^; I didn't mean to neglect you, but don't worry, I'm working on other Yullen stories, I have not forgotten you ^^

The Japanese paced irritably around the lab floor, his teeth gritting in frustration while his partner remained calm and collected, his eye focused on the object in his microscope, his hand playing with the focus of the instrument.

"You know Yuu," Lavi started, "if you're this bored, you can go do something."

"I can't," the Japanese sneered, "the order hasn't given me a new mission and won't for a while thanks to you!"

"No Yuu~" the redhead whined looking up from his microscope, "don't blame me~"

"I can and will blame you for this," Kanda hissed, "it's your own damn fault you got captured!"

"But it's not my fault that you got assigned to me," Lavi retorted smartly, his friend growling at the comment, cobalt eyes narrowing. "In any event," the other pressed, "I'll have something more for you to do in a day or two Assistant number 1; these results are inconclusive at best."

The redhead proved his earned nickname as the rabbit as he ducked expertly from his friend's blade, the metal slicing through the air where he stood, barely missing the young man by a fraction.

"Geez Yuu! Watch out for the equipment will ya? It's expensive!"

"Do not!" the other seethed, his dark aura pulsing around him, "CALL ME BY THAT NAME! And I especially hate being called your goddamned ASSISTANT!"

The one eyed rabbit swallowed his fear and he nodded, his singular eyes staring at Kanda while he tried not to shake under his friend's anger.

"Now," Kanda sighed, sheathing his katana, "just what makes your results so inconclusive."

"W-Well," Lavi stammered slightly, standing up and dusting off his lab coat, "y-you see, there are a few… anomalies."

"He's a vampire," the Japanese snapped, "everything about him is an anomaly!"

"True," the redhead agreed, "but he's special even among them!"

"How so?"

The black lab manual was flipped open, his fingers flowing down the page as he looked for the passages.

"Well, for starters, his blood cells are weird. While his blood is red, under an extraordinarily high magnification on the electron microscope, there looks like there's some sort of virus affixed to it, but I have never seen it and nor do I know what it is."

"A virus on vampire blood? That's new."

"That's the other thing," Lavi explained, "his blood isn't vampire, it's human."

"How can it be human?" Kanda whispered, his eyes wide and his brows furrowed in curiosity, "we've seen him, he's a vampire."

"I think it's the parasite," the redhead confessed, "from our limited knowledge, it is basically understood and accepted that a vampire's saliva contain a virus that, when injected into the victim, the virus, like all viruses, enter the cell and adjusts the DNA, making the human a vampire."

"I know that much," the Japanese snapped, "but what are you getting at?"

"Well, if it's a virus, there's a very likely chance that he was born with it and, as he matures, it becomes active over the years, acting like the original virus but to a greater extent. It's entirely possible that this one just replaces the DNA entirely with something else, its own."

"But… how is that-"

"It could be like the Herpes' virus," Lavi explained, "in that scenario, it undergoes Lambda replication, which is just a fancy term for saying that the virus just replaces a segment of DNA in the host and then just sits and waits patiently for the right time, dividing with the cell until a high stress scenario. It's possible that somewhere along his family's line, they got themselves infected but never showed signs as they weren't right, their genetic code perhaps didn't follow the right pattern or something along those lines until he came along, poor thing."

"So… are you suggesting that this is completely random?" Kanda asked, his arms crossed over his chest as he stared at the one-eyed rabbit.

"Given the combinations needed for this perfect storm, I'd say so yeah."

"Does that mean that we're-"

"Oh no," Lavi assured, "unless you've been drinking his blood or sucking him off-"

"LIKE HELL!"

"Then you're fine," the redhead simpered, "from my understanding, it looks to be transmitted through bodily fluid contact, not airborne."

"That's… good, I guess."

"But that also means everyone he's bitten is now infected," Lavi murmured, a somber look on his face, "and there's no telling how many that could be."

"So he's ensured his survival," Kanda muttered, "smart bastard."

"Yes he is," the green eye looked from page to page of his notebook, "but that just proves how strong Allen is."

"What do you-"

"I mean that his blood isn't an addiction like I originally thought," Lavi explained, "but… more like the viruses way of forcing him to do something and if Allen's fighting it, then I give him congratulations."

"How-"

"It's sort of like… being stuck at sea for a really really long time," the redhead went on, "and all you can eat is fish. After a period of time, you begin to crave not the actual flesh itself, but things like the eyes and intestines. After a while, your body wants more than just protein so, to get the necessary nutrients that it craves, it makes the fishes eye taste good to you and the meat bad."

"So, you're saying that the virus makes him want blood so that it can pass along its genetic code?"

"That's one possibility," Lavi agreed, "but another could be that the virus needs blood, though why I can't seem to figure it all out."

"And what did you need me to get?"

"For starters, more blood," the other mumbled, holding up the empty tubes, "but for another, we'd need a family history, what sort of diseases they had, what they died from, oh, and I'd like to ask a few more questions, more so about his habits and what he feels than anything else."

"And just how do you propose we do that? He won't talk to us without cursing at us or trying to bite us and he won't eat a damn thing!?"

Lavi sighed but he knew Kanda was right. Over the past two weeks he'd been in captivity, Allen had snuffed and scoffed at anything the two of them tried to force feed him, his lips shut when the spoon came close to his mouth, snarling and growling at the two of them, his silver eyes blazing, his brain trying to find new ways to trick them into giving them their blood.

"I might have a way," Kanda told his partner, his lips curling into Devil's horns, his cobalt eyes mischievous as he looked over at Lavi's curious face, "get your clipboard."

"Good morning, moyashi."

Silver eyes turned weakly to the advancing figure, his nostrils flaring as he could practically see every vein, artery and capillary running through the man's body, his blood lust having grown exponentially since his first capture.

"What do you want," he snarled at the samurai, his eyes narrowing as he looked at the smirk the other affixed onto his face.

"We just want to talk is all," Kanda told him, the bunny following behind him just as confused as Allen was.

"Yuu, wh-what are you gonna-"

"Getting your answers," the Japanese explained, his sword drawn from its sheath, the metal glinting steely in minimal light.

"What, you're gonna beat it out of me," the vampire snorted, "don't you know you can catch more flies with hone than with vinegar?"

"Yes I do," the hunter agreed, surprising everyone when he suddenly straddled the slim hips, "but in your case, I can catch more flies with blood."

Silver eyes went wide as the blade was raised to the man's palm, the wrist flicking it over the flesh, the red mark left it it's wake filling quickly with blood, the scent driving Allen mad with hunger, his mouth practically salivating at the Japanese brought his bleeding hand towards him, the younger stilling on the bed as the blood was brought to hover above him. Without warning, his body lunged for it, his mouth open as he internally cursed Kanda for his reflexes, his hand brought sharply upwards, dangling just out of his reach, even when he extended his pink tongue towards it, saliva unconsciously slipping down his chin.

"My my, aren't you hungry," Kanda teased, his lips curling into a wider smirk as the creature tried desperately to taste him, his small tongue flicking out for him, Kanda deciding to offer him a singular drop on the vampire's tongue, his hand tilting to allow the blood to run down his long finger until the red dot hit the slender muscle.

Allen let a sigh slip as he swallowed the minimal blood, his eyes rolling back in bliss as he finally attained his long awaited prize, his silver irises opening at look at the man on top of him

"Yuu!" Lavi screeched, "what the hell! We can't give him any blood remember? We need-"

"-answers too," Kanda finished, his cobalt eyes looking down at the other in interest, "and this is the best way to do it, we'll have to taint the samples then, sorry about that."

"Wh-Wh-"

"If you want more of this," the Japanese told him, the blood pooling in his hand shaken above the vampire, "you'll answer the questions, truthfully I might add. You lie, and I take away your meal."

The slim figure swallowed, his eyes darting from the hand to Kanda, his mind raging as he battled with his pride and his desire, his chest heaving as he bit his lower lip.

"What do you want to know?"

Kanda's smirk turned to Lavi, the other shrugging his shoulders before he picked up his clipboard.

"Full name?"

"Allen Walker," the vampire responded quickly, his eyes glue to Kanda who begrudgingly gave his a drop off his index finger, the younger swallowing it with the same swiftness of the first.

"Age?"

"Eighteen."

"First time you felt the blood lust?"

"I guess I was sixteen," the creature admitted, "don't really know, I've always had pale skin," his mouth releasing a sigh as Kanda slipped a few more drops into his mouth, his tongue running over his coral pink lips.

"Okay… have you ever changed, other than from human to vampire?"

Silver eyes darted around his body betraying him as the scent of Kanda's blood overwhelmed him, the actual taste unlike anything he'd ever had, neither sickly sweet nor bitter, a full-bodied flavor that he doubted he'd get bored of.

"Once or twice," he told them lowly, "I'm not entirely sure, I don't remember it, I get black outs."

Lavi scribbled his answer down while Kanda rewarded him, the redhead adjusting his steel clipboard, "alright then, what about family history."

Curious silver eyes looked over at him, "why do you want to know that."

"Does it matter," Kanda snapped, "just answer the damn question."

Defiance settled into Allen's features as his head turned back to the Japanese.

"Fine," he murmured lowly, "I don't know."

"Not good enough," the hunter growled, pulling himself off the boy and slowly wiping away his bloodied hand, Allen squirming against the binds.

"It's the truth!" the vampire protested as he tried to lift himself up to look at the other in the eye, "I swear, I never knew my parents, I was abandoned on the streets when I was a baby where my adoptive father picked me up and cared for me until I turned eight. He died when a carriage careened into him and I've been on my own ever since!"

"You're lying-"

"No I'm not!" Allen nearly screamed as he struggled against his shackles, "I swear, I'm not lying to you!"

"You're going this far to convince me," Kanda murmured softly, "you must be desperate for blood."

"I don't know why," the half-ling confessed, "but ever since I turned sixteen I've been hungry for blood, hunting, stalking, taking my prey. I tried, I promise you, I tried to ignore it, lock myself away and never come out again but…"

"But what?"

The creature swallowed, "whenever I didn't feed, I could feel something within me growing stronger as I grew weaker, trying and teasing me that it would take over, laughing at my resistance as I struggled, whispering cruel things to me."

"So you began to drink blood again," Kanda finished as Allen nodded.

"I saw what it did," he murmured hoarsely, "I would have a blackout and wake up, blood stained clothes and a trail of destruction left behind me. If I drank blood, the voice would stop."

"But," Lavi injected, "if you feed, the thing inside you becomes stronger."

"Yeah," Allen laughed pathetically, "irony huh? I feed and it gets stronger, I don't and I get weaker."

"If you expect me to feel pity for you-"

"I'm not," the vampire told him determinedly, "I just don't want him to come back, I hate hearing his voice, hate the thought that he might one day win, hate the thought that… I'll be gone, just like that."

Cobalt eyes looked at him uncaring, his face impassive as he turned to leave up the stairs, the clanking of chains reaching his ears as Allen struggled against them.

"I answered your damn question!" the boy screamed, "you made a promise, honour it!"

The door slammed, stunning the slim boy into silence as he stared up at the stairs, his face falling before he flopped back onto the pillow, his hear cracking as he thought how pathetic he must look, how dejected he seemed, even to himself.

"That's uh… that's it," Lavi's voice cut through his thoughts, his finger fidgeting out of nervousness before he shoved his things into his bag, "I'll come down later for your dinner."

"L-Lavi," the vampire sniffed, tears pricking his eyes as he turned his head to the other, "d-do you think you could give me something, j-just a little taste?"

The redhead swallowed at the sight, Allen looked so pitiful his heart clutched, the young man trying to figure out a way to help him, the knowledge he had already gathered stopping him.

"Sorry Allen," the young man mumbled, his mind winning over his heart, "I can't."

The vampire's face turned from sorrow to anger in a heartbeat, his fangs elongated as he practically growled at the other.

"So he's a liar and you're a coward," the creature seethed, "when that other creature rears his ugly head you'll wish you fed me when you did."

The young man said nothing as he took up the stairs, Allen's eyes glaring at him the entire way, his body practically shaking with anger, his face turned and buried half of it into his pillow as best he could, his body tensing against the shackles as he willed himself not to break, to stay as strong as he was taught. The door opened swiftly and shut just as, his curious silver eyes looking around to match the boots to the footsteps, surprise in him as he saw Kanda descend the stairs, his sleeve rolled up and a small bag in his hands.

"I may be many things," the elder warned as he approached the bed, "but I am not a liar."

The boy looked shocked as the Japanese handed him the pouch, the contents still warm as a corner was ripped off, the opening gently offered to Allen's mouth, the vampire accepting the drawn blood with haste, his eyes rolling back in pleasure as he drank, the flavor running over his mouth and taste buds, small moans unconsciously slipping from his mouth as he took in his fill.

"Didn't know I tasted that good," Kanda murmured as he gently took back the now empty package, silver eyes glaring at him.

"Don't flatter yourself," he snapped, "I was absolutely famished, you could have given me rat's blood and I still would have enjoyed it."

"Che," the elder scoffed, "don't get used to it, this is just me holding up my end of the deal."

The elder turned around and trudged up the steps, the vampire watching him the entire way, the vampire stopping him in his tracks, his voice soft and melodic, kinder than Kanda ever anticipated.

"Thank You, Kanda."

Review please ^^
