PLEASE READ THE AUTHOR'S NOTE BEFORE READING THIS FIC

AN: This was inspired by my other Trigun fic, The Pawn.

I wrote this based heavily upon the manga universe. If you know anything about the manga, you know that the characters and events in the manga are significantly different than that of the anime. Do yourself a favor and don't read this fic with your "anime-glasses" on.

That said, if I had to pin a time frame on this baby, I'd probably say that this fic is set to occur somewhere around volume 5 and 6 of the Japanese release of Trigun Maximum. This fic is also an AU of sorts in that I launch into my own universe with the events leading up to volume 5 having already occurred.

Aside from the Trigun/Trigun Maximum mangas, this fic was also inspired by Rosemary's Baby. If you hated the way that movie ended, you'll probably dislike the way this fic ends. Get the hint? Not everything in life has the cliché "and they lived happily ever after" ending. I have other fics with that type of ending, so if you're looking for that, you might want to reconsider reading something else.

Consider yourself warned.

Double Helix

prologue
a beginning is a very delicate thing

Knives pressed his lips together grimly as he stared into the plant core, a flash of sorrow and rage reflecting in his eyes, "I know."

Legato paused for a moment, sensing his master's anger and frustration beginning to mount. This was very delicate ground to be treading upon and it must be navigated carefully. The last thing Legato wanted was to upset Knives, his only desire was to do as He willed.

"Conrad is above," the cripple said. "He wishes to speak with you."

Legato felt a tide of frustration and rage roll in as the last of his master's patience was steadily ebbing away. Not wishing to further evoke Knives' frustration and ire, the blue-haired servant continued, "Master, it will please you to know that he thinks he may have found a solution..."

The free-born plant paused, his eyebrow raising curiously. A sigh of relief almost escaped Legato's lips when he felt the tide of anger begin to recede ever so slightly.

"A solution?" Knives asked. The question hung in the air, demanding no reply. "Let's hear what the maggot has to say then."

Turning on his heel, Knives left the room with the pallbearer quietly pushing Legato behind him.

As they made their way through the maze of corridors and stairways, Legato let his mind churn over the possible reasons why his master had been so particularly agitated as of late. The free-born plant had been seething since he first learned of the hair-darkening effect. Impatiently seething.

Now it seemed that the seedling was dying. Knives' greatest desire was slowly fading away. It wouldn't be long before there was nothing left to hope for, only revenge.

Shifting his weight from one foot to the other, Dr. Conrad exhaled impatiently. The arthritis in his left knee was screaming at him to sit, but the doctor knew better than to let his guard down in such a place. Leaning his back against the wall did little to alleviate the soreness in his joints.

Legato was making him wait on purpose. It was his petty way of reminding Conrad of his position in the food chain.

Dipping his chin to his chest and closing his eyes, Conrad finally heard the welcoming sounds of footsteps approaching. He immediately straightened himself, smoothing out the wrinkles in his shirt when Knives made his appearance.

Conrad offered a nod of acknowledgement as he greeted the plant, "Hello, Knives."

Silence answered him as Legato and his pallbearer paused behind their master. Disgust crept into Conrad's belly at the sight of the cripple, but he kept his face as stoic as possible.

An ice-blue smirk caught the doctors attention, trapping him within Knives' steady gaze. Silence tended to unnerve humans and the free-born plant was more than happy to use the vacuum of noise to his advantage. The sarcastic twist of Knives' lips only grew more satisfied as he watched tiny beads of sweat glisten on the doctor's brow.

The plant relished in the discomfort Conrad felt. It was the very least the old bastard deserved. Conrad had been pleased when he saw Knives' hair begin to darken and did little to hide the emotion from Knives' probing mind.

It was enraging, but Knives suspected there was far more that the doctor knew about Plant biology than he professed and that made him an important part of the equation. He would simply have to wait. The time would come when Conrad would no longer be needed and Knives looked forward to the feel of dismembering him.

"You have news for me?" Knives asked sardonically, his clear voice cutting the silence to shreds.

"Ah, yes," Conrad squared his shoulders. "I do."

Knives moved to stand closer to the doctor, all the while probing his mind searching for deceit and finding only disgust and annoyance directed towards his maimed servant. The free-born plant almost laughed aloud and the absurdity of it but decided to humor the old man instead.

"Legato. Leave us."

The servant nodded in reply. Without a sound, the living corpse and his pallbearer retreated from the room. Once the two were alone, Knives offered the doctor a sarcastic smile. "He makes you nervous and I do not?"

"No, that's not it," Conrad said carefully. "He's just... very unnatural. I can't explain it."

The smirk quickly developed into a laugh of genuine amusement at the doctor's ironic admission. It was true, Legato was indeed an unnatural being, yet a useful one. All of the humans Knives surrounded himself with were somewhat unnatural. A few of them were not human at all. That was the very reason Knives chose to surround himself with them. All the better that some of them were considered to be ‘disturbing.'

As the amusement drained away, Knives locked eyes with the aging doctor and made his simple demand. "Tell me."

The doctor took a deep breath and began. His voice shook with nervousness at the beginning, but as he told Knives what he had discovered he became increasingly bold in his statements. Knives only occasionally interrupted him to ask questions or to clarify a finding, but not once did he lose his temper or threaten to lash out against the doctor for what he was suggesting. Conrad was quite surprised at the calmness of Knives' reaction, realizing all at once how desperate the free-born plant was to set his plans into motion. When it was all finally said and the details thoroughly explained, Knives only stood there in front of the old human, his mind working over the nuances of what he had just been told.

"I don't like it," the free-born plant said finally.

"I didn't think you would, but I thought the information could be useful."

Knives only nodded as he clenched his fists at his sides, clearly aggravated. The more he thought about it, the more his anger mounted. This was not the solution that Knives had hoped for. It was preposterous. Surely, the old man thought of something better than to use one of them.

"That is your suggestion then?" Knives glared at the doctor, "Your only suggestion?"

Conrad bit back a grimace at the tone of malice in Knives' words, "It is the only one that I think has a real chance for success." He paused as he watched the plant grow increasingly tense. "I will need some biological samples from the Red Dune Laboratories first just to verify that my initial hypothesis regarding the Ryoushi bloodline. Then I will need current biological samples for further verification. If I am correct, then I think we should try for immediate implantation."

"How can you be so certain your hypothesis is correct?" Knives asked, not bothering to hide the doubt in his voice.

"I- well, I can't." Conrad admitted, "However, the circumstantial evidence indicates that significant chromosomal mutation must have occurred. It's certainly worth investigating. I think in this case, we should assume that some level of mutation has occurred. If that's the case, then we may be able to use that to our advantage."

"My advantage, or yours?"

A slight smile tugged at the doctor's lips and he shrugged his shoulders. "Both. Yours more so than mine, of course."

"Of course." Knives sneered, turning his back on the doctor. The temptation to kill him was far too great if he looked at the human. Turning away from him was all Knives could do to keep from skewering the old man.

The blood lust had peaked as the free-born plant listened to Conrad's monstrous suggestion and now that urge was a tangible ache. Certainly, the old man realized that what he was proposing was not only morally degrading, but also abhorrently slanderous. Did he honestly believe that any of them would relish the idea of entrusting their survival to the flawed biology of a Homo sapien?

Yet, the old man was perfectly serious and had sound reason to back up his preposterous theory. Knives couldn't argue with the human's logic and that, in and of itself, was infuriating.

"Your proposition is disgusting," Knives said finally as he opened his mind to his family. When the cacophony of voices became too much he silenced them in both thought and whisper, "This seems to be the only option available to us now."

The doctor remained silent as he waited for Knives to arrive at a decision. Seconds flowed into minutes as the room became thick with anticipation. Feeling ensnared by the tension, the doctor found himself suddenly speaking when he knew he should not.

"If I'm right, then her direct descendents are not completely human anymore, so..."

Knives turned his head and glared at him sharply, causing the doctor to trail off into silence.

"Not completely human?! You think that makes a difference to me? This is an abomination!" Knives yelled just before turning his back to the doctor again. Willing himself to keep his rage in check, the free-born plant began to tremble, the flesh on his hands and arms throbbing painfully. His fists continued to clench and unclench beside him anxiously; small dagger-like knives began to bud along his arms.

This was not what he had planned; yet, at every attempt to set his plan into motion he had failed. Failure was not acceptable and the alternative just suggested to him made his blood boil. There really was no other choice. If he did not do as the doctor suggested the seedling would most definitely die before it had a chance to live.

It had to live. It had to. It was the future.

If this was the only viable option to ensure the survival of the seedling, then Knives had no choice.

The doctor saw the tension drain out of Knives' back and the small buds shrink back into his flesh and knew that he would soon know what Knives' desire was. His breath caught in his throat as he waited.

Knives slowly turned around and faced the doctor fully, his eyes glowing dangerously in the darkness of the room. "Be ready. We're going to do as you suggest."
