Reply and tell me what you think is going to happen. This is NOT the end.

This chapter may be slightly graphic for very young users, i myself don't find a problem but you may

Okay, I made some of the things in this chapter invalid, it's only so it can fit into the plot, i'll start explaining exactly what.

1) Hedgehog's backs. I'm making it so there are two shells that protect the spine, hedgehogs do not really have this, and i'm putting it in because they would need it to be able to Spin-Dash and break through metal.

2) Cerebrospinal fluid, it is indeed a real fluid, however, it is one of the most quarintened systems inside the body. You are born with it, and there is no exit point in which the fluid is flushed out. It is a continues cycle and will always have the exact same amount.

On with the story!


Helen looked around all confused on the bed in the tiny medical bay Tails had. Shadow was talking about something in a low muffled voice, as was Tails, Helen couldn't say what they were talking about. She also couldn't see through the tinted glass.

She sighed and leaned back, looking at the cracks in the ceiling for entertainment.

Shadow stood on the other side, talking lowly to a pondering Tails.

"A buildup of fluid? Are you sure?"

"I'm not, that's why I'm talking to you. I want a full scan of her; make sure it actually is fluid, or a blood clot, something besides bone." Shadow muttered back, getting a shocked look from Tails.

"N-not to be mean or anything Shadow, but w-why do you care?"

Shadow looked through the one-way glass, Helen was completely board, you could tell by the look on her face.

"I owe her; I wasn't the 'best' Chao." Shadow muttered, more ashamed than embarrassed.

"It's okay, I'm sure she forgives you." Tails offered, walking out with a tiny scanning device, it was a miny X-ray machine, a lot better than the large clunky things used in hospital.

"Hey Helen!" Tails piped up, walking through a door, at once Helen's face brightened up and she waved.

"Hi Tails! Do you have any idea why I'm here?" Helen asked, genially confused, Tails looked at Shadow who shook his head.

"Sorry, but I'm not allowed to say, can you roll over please?" Tails asked, big blue eyes sparkling. Helen nodded and sent a suspicious look at Shadow who returned with a Sable-I'm-innocent! Face.

Slight beeping as Tails moved it down Helens back, with a slight nod to Shadow, he pointed to a spot a little bit further down than half, that was where the buildup was.

"Okay, thanks Helen! Do you want anything? A drink? I have a TV you could watch." Tails offered, a few minutes later, Cream was sent up, braiding flowers with a very happy Helen.

Tails and Shadow walked into the room, Tails nodded to Shadow.

"You're right about the fluid pocket, but why do you want to know where it is?" Tails innocently asked, tilting his head. Shadow closed his eyes but opened them quickly, very slowly walking to the glass.

"I am the Ultimate Life Form, immortal in all ways, impervious to all diseases and almost invincible." Shadow noted, Tails nodded to this, not completely sure where this was going.

"I was made to help Maria; she had NIDs, a syndrome that had very weak white blood cells." Shadow winced all through this; Tails bit his lip, not wanting to dwell further into the topic.

"I have blood with invincible white blood cells, when connected in the heart, the cells would multiply and the disease would be destroyed." Tails' eyes lit up with excitement with this discovery.

"But with that, it would cause her to age slower because of the limit they had." Tails' ears dropped, no,
Shadow couldn't help mankind that way.

"So where does Helen come into this?" Tails asked, looking out at the laughing Helen, she gently set a crown on Creams head and laughed as she got one in return.

"Helen's condition is biased on a disease, not an accident. The disease it not natural, therefore my own immune system would fight it." Shadow stated, Tails spun suddenly, eyes wide and tails trembling.

"You aren't going to turn her immortal!" He shouted out loudly, and suddenly. Shadow's eyes held another glint, a satisfied glint.

"Cerebrospinal fluid is wasted quickly; it seeps into the brain then moves out of the sinuses. Within two days it would be out, and the damage would be fixed. It wouldn't make her be immortal." Shadow corrected. Tails sighed in relief, and then suddenly they lit up in horror.

"Wait, how are we going to get this out of you?"

Shadow's grim smile was his reply.

"AHH! SONIC!" Tails screamed, running for his life and flying out of reach of Shadow. At once, Amy, Sonic, Ella, and Chris appeared, slightly surprised by Shadow's presence.

"Tails!" He shouted, quickly spin-dashing Shadow away from his brother. Shadow skidded across the floor, looking up with a strange look in his eye.

"He's work." He stated, causing Tails' eyes to widen.

"What? No! He'll kill you by accident!" Tails shouted in fear, Sonic looked on in confusion.

"Wait, what is going on?" Sonic asked, holding up his arms.

"He wants me to split him open!" Tails cried out in fear, hiding behind his older brother.

"Correction: your strength is not great enough to 'split me open'. Rouge would be my first choice with her lasers-"

"Lasers!" Tails cried out, shaking now.

"-But she doesn't know the bone work of a hedgehog. The Guardian could work, but he would cause long lasting damage-"

"And Sonic won't!" Tails cried out, once again interrupting Shadow who growled in anger.

"He's crazy Sonic! Help!" Tails cried, pulling Sonic with him as they backed away slowly.

"Whoa Shads, have you gone all Emo on us." Sonic blinked, raising his hands in a sign of truce. Shadow smirked.

"Actually, it's a little medical experiment for the greater good. If you want to help, sure, if not I always could get Rose…" Shadow trailed off, Sonic winced, but took a few steps forward.

"Sure, what do I need to do?" He blinked at a sad Tails.

"I'll get the scalpel." He sighed, Sonic twitched.

"Huh!" He demanded, eyes widening at the thought of the surgical knife.

"Stop it! It's not for you!"

"Should have told me Sunshine!" Sonic taunted like he did as Swift, he then turned and dashed out of the room after Tails. Shadow shook his head and followed.

Helen passed Shadow on the way up, in her wheelchair and looking completely confused. Cream was pushing her, and apparently, this was going to happen. Tails held open the door, apparently Helen was just inside the observation room, the main room was behind a cleverly hidden door.

"Oh man….I'm starting to regret coming here." Sonic muttered, looking at the sharp objects lying around, mostly a tray of needles and a bunch of vials.

"Then I shall grab the guardian." Shadow noted, Sonic spun only to see the flash of Chaos Control fade. Tails looked around a tray.

"Where did Shadow go?"

"He went to get Knux incase I had any second dou-"

Another flash and Knuckles hit the floor, thoroughly dazed. Shadow stood up, not an emotion on his face.

"Wha? What was that for Shad-"

"You are needed." Was Shadow's blunt reply before moving to the corner and closing his eyes. Knuckles looked around confused to Sonic who shrugged, than to Tails who refused to meet their eye.

"Okay, Sonic, I'm going to need you to-"Tails winced for a slight bit, Shadow smirked slightly.

"To what?" Sonic asked, confused, as was Knuckles.

"-to break through the bone blade, and Knuckles, you will need to break the bone covering." Shadow finished, causing both to pale.

"Wait, whose bone's are we breaking-"Knuckles started, causing Sonic to shiver.

"And what for?" Knuckles crossed his arms and Shadow sighed, looking down and frowning.

"What for? Medical purposes, and for whose bones? Mine, you'll be breaking my back."

The two jumped away, eyes wide, filled with shock.

"What? No! As much as I've wanted to punch you before, I'm not going to break you!" Knuckles protested, Sonic exhaled shakily, as was Tails.

"Shadow, you know that this is going to hurt, right?" Sonic noted, Shadow nodded slightly.

"You'll have to work fast, I heal quickly." Shadow noted, grabbing something next to Tails and inhaling quickly. Tails spun around, barley grabbing Shadow and holding him up.

"Argh! Help me guys!" He barked out, Knuckles raced forward and grabbed Shadow, propping him upright even though he wasn't moving.

"What was that?" Sonic yelped, not even wanting to touch the nasty smelling cloth Shadow inhaled.

"It's a tranquilizer, but I didn't think that we would be doing this now!" Tails yelped, directing Knuckles to set him on a table, Sonic winced at the flopping noise.

"Guess we're too far to quit." Sonic noted, Tails nodded and breathed deeply, snipping out two holes for Shadows back spikes, on a blue surgical cloth now draped over him.

"Knuckles! Get those two wires and clamp them over his right wrist!" Tails shouted, Knuckles did as he was told, and the familiar beeping noise on most doctor soap operas came on, Sonic was faintly amused by this.

"Okay, we need….to get the fur off of the cutting area…" Tails gulped and Sonic snorted, imagining a bald Shadow.

"You know, I've always wondered what his skin color was." Knuckles faintly mused, Sonic nodded with agreement. Tails grabbed the razor and quickly cut off a large area of fur, just at the base of Shadow's back quills.

Sonic peeped over and frowned.

"Aww, its black, I guess the markings are skin deep also." He was slightly saddened to see that it wasn't anything embarrassing.

Yellow soap was cleaned over the area, Tails was quick about it and Knuckles frowned at the soap.

"Hey, isn't that what they use for Cha-"

"No way.' Sonic cut him off, not wanting the creepy smelling goo on him. Knuckles blushed and looked down.

"Okay." Tails sighed shakily taking a step back. He looked at Sonic, who only blinked.

"Huh?"

"Oh yeah, he never said where to aim…" Tails dragged off and walked up to the two pointy back quills.

"Aim at the bottom of the quills, right around…here." He traced an area near the base and Sonic nodded, tensing his legs and jumping.

Knuckles shielding his eyes and flinched when the sickening CRACK of bone snapped, Sonic jumped away, pale and shaking. Knuckles also noted the blood on the top of his quills. Tails stepped forward, tails between his legs, and pulled back at the flesh, clipping it back.

"Eww…" Sonic winced at the black blood and the greenish blue muscles just visible under the bone shell, which gently had its chunks taken out.

"Okay Knuckles, your up." Sonic muttered, pushing his friend forward. Knuckles gulped and Tails traced the area where to punch, on one side vertically on the bone ridge.

CRUNCH! Tails moved in quickly, hoping nothing had pierced the thin membrane of the vertebrae. To his luck, nothing did, and the smallest of small pieces, were already fixing the crumbly edges.

"Thanks-s Knuc-ckles. Can you grab the n-nee-d-"Tails stopped talking as Sonic walked over, giving him the needle.

"Sorry Shadow." Tails apologized in advance, before piercing the thin, egg like casing of the fluid.

At once, the casing healed, trying to force out the needle, but not before Tails got a vial full, plenty enough to help Helen.

"Okay, no we mount the bone back." Tails smiled shakily and grabbed a thin metal ridge, already in the shape of the casing. Bolting it onto the bone there, the other bone was set back into place, as was the outer plated needed to protect with spin dashes.

Tails pulled the skin back, and grabbed a needle, stringing it floppily back together.

"Okay, we're done." Tails smiled and Knuckles bolted for a sink, trying to wash off the black salty smelling blood.

"Get it off, get it off." He whimpered, as did Sonic as he washed it.

Amazing, the sign of mutant alien blood of a friend coating your hands and head was enough to make them drop this low, not to blame them, Tails wanted to throw up.

"The drug should ware off any minute, so if you want, you can wait here, or you can l-"

Knuckles was already gone, jumping out the window, back to Angel Island as he knew where it was….somehow.

"Oh god Tails, why did he want that? IT was horrible." Sonic muttered, finally getting the blood off of his face. Tails smiled, now one with an accomplished look to it, and laughed.

"You'll see in a few days if it worked."

"Yes, it'll be good." The words were slurred and came from a really dopey black hedgehog.

"Shadow! You're awake! But how are you talking after that? Normally it takes hours until one can talk again." Tails frowned, hurrying over to undo the heart rate machine. Shadow laughed tiredly.

"Ya' kiddin' me? I'm used ta' this." Shadow groaned, and Sonic couldn't help, he laughed.

"Dude! You sound like your drunk!" He cracked up, causing Tails to laugh to.

"Yeah, D'cter said tha' b'fore." Shadow groaned again, trying to roll over, only to have Tails help him into a sitting position.

"Doctor?" Sonic looked to Tails for an answer, he got a shrug instead.

"Must be when he was created, pretty well done I say." Tails commented. The way the fog in Shadow's eye was clearing, he was coming around.

"Geez, I feel as if I got nailed by a training bot." Shadow moaned, blinking a few times.

"Huh?" Sonic blinked clueless, Shadow sighed, finally seeing who he was looking at.

"Stepped on by Biolizard." He changed, getting a smirk from Sonic in the process.

"So, did you get it?" Shadow asked Tails who grinned, helping the still slightly dozy hedgehog to his feet.

"Yep, do you want to give it right now?" Tails asked, not caring about the oblivious Sonic.

"I'm dozy anyways, might as well. I want to sleep." Shadow grunted, making his way out towards the main room and collapsing on the nearest bed. Sonic blinked and sighed, moving him so he was lying on the bed completely without hurting his back in anyway. That and the fact that the stitching was black, almost impossible to see with his black fur and skin.

"Tails? You wanted to see me?" The door opened and Helen rolled in, moving towards a bed near Shadow and giggling, poking his belly. He mumbled something not recognizable and swatted her hand away.

"Hey Helen, ah I see you found Shadow. He's really out of it, there was something in his back we needed to get out, so try not to touch there." Tails cautioned and Helen nodded, giggling as Shadow groaned and his eyelids fluttered, still staying closed.

"Hey Tails? Is he drugged? I hear drugged people can't lie." Helen offered, Tails smiled slightly and nodded. Helen tilted his head and tried to make his face line up with hers.

"Shadow? Shadow, wake up Shadow." Helen sang in a sing song voice, appropriately making Shadow frown and swat at her.

"Gway!" He groaned, making her giggle again. By now, Tails had come out, and was holding the needle with a tranquilizer and the reversal.

"Come on Shads, wakey wakey, stop sleeping." Helen tisked, almost cracking up at the tiny pout on his face. Tails was grinning and he gently poked Shadows right ear, causing it to flicker.

"Please Shadow? You promised to get up today!" Helen pouted, almost cracking up herself.

"And I promise to go to sleep tomorrow." Shadow wittily replied back, almost as if he had said this many times before. Tails silently slipped from the room.

"Watcha mean?"

Shadow frowned, using his arm to cover his eyes. The door opened and Sonic snuck inside, looking at Shadow with a tilted head, a slight frown.

"That isn't going to keep out the light you know."

"Good 'nuff for me." Shadow groaned, and Sonic jumped, at how alike the two were at the moment.

"Come on Shadow."

"But I'm tired!" Shadow whined, this time, Sonic couldn't hold back a snort. Shadow moved the arm and peeked out with a glazed eye.

"Leave me 'lone Maria." He groaned, before his head fell weakly against the pillow, definitely asleep.

"Well, that was amusing." Tails noted and Helen smiled, giggling slightly.

"Okay, well, here, breathe this a little and lean back okay?" Helen nodded and took the cloth, hesitantly inhaling. At once, her eyes fogged up and she leaned back, sliding into sleep.

"Okay, can you go for a moment Sonic?"

"Sure little buddy, see ya soon." Sonic winked, walking out of the room. The door closed and Tails gently rolled Helen over, proceeding to gently push into Helen's spine until he felt slight resistance. It was then he knew that he was at the area needed.

The fluid drained quickly and Tails retracted the needle, after waiting a few seconds, he injected the antidote to the tranquilizer and waited. Sure enough, a few minutes later, Helen bolted upright, seeming confused.

"Huh? Looking around confused, she shrugged, feeling tired she lay down once again, falling asleep.
