This is my first attempt at a SLASH fiction so please be kind while reviewing. I know the first few chapters wont seem like much slash but I'm hoping that the longer I work on this the better I'll be at it. By the way the first few chapters are mainly going to be centered about Greg, I'll try to get deeper inside Nick's head in later chapters. I hope you enjoy this story because I am having a blast writing it.

Greg Sanders walked out of the bar him and his friends/co-workers were at celebrating closing a case that involved the murder of five-year-old Miranda Wellington. Greg was the one who discovered the evidence that put Janet Wellington (her mother) and her boyfriend Ralph Warren in prison. The damning piece of evidence was a strand of hair encrusted into the fatal wound that was caused by her mother smashing the back of her skull in with a baseball bat.

Everyone had been extremely disturbed over this case. This was not the first case that involved the murder of a child but the reason this had struck such a hard core was because her mother's boyfriend had raped the child before she was killed. Nick had been extremely affected by the case because when he was younger his babysitter had raped him. Grissom had repeatedly asked if he should take him off the case but Nick kept telling him that he was fine and that he could handle it. But tonight they had found out otherwise when Nick had had one too many drinks. He admitted to having broken down in the locker room soon after discovering that the child had been raped and continued to break down with each passing day the murderers and rapist were at large.

Greg was too intoxicated to be driving so after his fifth or six drink he called it a night and said goodnight to everyone. His plan was to hail a taxi but luck was not on his side because no taxies appeared to be heading his way so after waiting for 30 minutes he decided to walk home.

The rain hammered down onto the cars, pavement and of course Greg himself. He trudged along in his soaking clothes, shivering, most likely going to catch phenomena, if he had to be sick he hoped for the first option. As he was passing an alley he was yanked inside and slammed up against a brick wall that scraped at his exposed back. A knife was whipped out by the man restraining him and pressed the blade up against his jugular. Greg couldn't help but feel regret that if he were to die he would never be able to tell Nick how he really felt about him. "Don't worry Greg, we're not going to kill you" said the man. Surprisingly it wasn't the fact that the man holding the knife knew his name what scared him was that he had said there were more guys hiding in the darkness.

"What do you want?" he asked the man with a slight tremor in his voice "we just want you to join our 'club'" a man stepped out from the shadows wearing a completely black outfit cradling a smooth metal case. The man stopped next to the man restraining Greg and unlatched the case to reveal a syringe filled to the brim with a blue fluid. Greg's eyes widened in fright and he began to struggle. "The more you struggle the more painful my grip will become" the man's grip increased and Greg cried out. The shot was taken out of the case and glistened in the gleam from the street lamp "ready to become a member?" Greg could only stare on in horror as the needle came towards his neck and flinched when the needle punctured his skin.

The fluid entered his bloodstream and almost immediately his body began to violently shake, he continued to be restrained until his body stopped shaking and his chin slumped down to his chest. The man with the case checked his pulse and was pleased when he found one, he nodded to the man beside him and Greg's body was carried over to a black van and placed inside the van; once the two men were inside the van the vehicle took off into the night.

Many hours later Greg woke up in his apartment on his bed with an aching hangover. Greg slowly sat up on the bed and carefully planted his feet on the floor, wanting to be careful not to topple over with the way the room was spinning.

He stumbled into his bathroom over to the toilet where he made it just in time to throw up the contents of his stomach. When he was done throwing up he rested his head against the cool tile floor and prayed to the gods above that his murderous headache would go away. Not liking the sick taste in his mouth he slowly got up from the floor and dragged his body over to the sink to wash his mouth out. He cupped his hands under the flow of cold water and sipped the water into his mouth and washed his mouth out.

After his mouth felt relatively clean he looked up at himself in the mirror and was stunned when he saw a few specks of dry blood on his shirt collar. He craned his neck and saw the cause of the blood, a small hole in his neck, most likely from a shot of some kind. Upon realization the memories of last night came back.

Him coming across the alley, being pulled into the alley, knife being held against his throat, two guys that knew who he was and wanted him to join some 'club' of theirs and finally the injection of the shot.

"Oh god" he breathed, terrified that he had no clue as to what had been injected into him and even more freaked out because he had apparently been brought back to his own apartment meaning they knew where he lived. His heart rate accelerated and he felt as if his throat was closing up on him. He gripped the edges of the sink and struggled to take in deep breaths. "Come on Greg calm down, you can't help yourself by having a panic attack" he scolded himself. His breathing and heart rate eventually evened out and his mind was clear of enough panic he finally noticed the bloody bandaging around his right arm. "What the hell?" he straightened himself out and gently started pulling the bandage off, whatever had happened to his arm had to have been pretty bad because a huge oval of dried blood was on the bandage.

The bandage was finally off after a few moments of having to get enough courage to actually find out what had happened to his arm. He prayed it wasn't another injection. Just as he was about to look down at his arm his phone went off. Saved by the ring! He went as fast as he could out of the bathroom and over to his ringing phone. He picked up the phone and as he was about to say hello his still aching head punished him for moving too fast and he had to take a moment to soften the pounding in his head.

"Greg?" said a voice on the phone. Greg brought the phone up to his ear and responded "hey Grissom" Greg said, all ready knowing who the caller was by the time on the clock that said he was pretty much an hour late for work. "Why aren't you at Work, are you sick?" asked Grissom although he had a feeling that the sickness was a hangover. Greg looked down at his arm and was shocked into silence. On his arm was a small array of digital looking cubes and circles that on closer inspection were tattooed onto his arm. "Greg? You still there?" Grissom asked concerned "yeah, yeah I'm still here. Listen um, I'm not feeling too well so I think I'm going to stay home today" his eyes were still trained on his arm in shock "okay Greg I'll see you tomorrow then" Grissom hung up and Greg slowly placed the phone down.

He was suddenly overcome with a pain that started from his head that spread throughout his entire body. When he took a step forward he lost his balance and stumbled until he crashed against the wall. His entire body felt like it was being torn apart from the inside out and all he wanted to do was lay down on the floor and die just to get away from it all. He suddenly found that his body was starting to tip backwards but that was impossible because he was standing up against the wall and he also noticed that the temperature in the room was colder on one side then the other. This was when he noticed that his legs were laying in his living room and his upper body was in old Miss Jenkins kitchen who was staring at him in shock.

"Sorry Miss Jenkins" Greg quickly sat himself up and was once again completely in his living room. "What the hell is happening to me?" he said aloud. As he sat on the floor he realized that he didn't tell Grissom about what had happened to him last night. Why didn't I tell him? He thought to himself as he walked back to his bathroom. Along the way he shrugged out of his shirt and carelessly dropped it onto the floor.

Once he was in the bathroom, like a mindless drone, he peeled the rest of his clothes off his body and turned the shower on. His mind must have been going on autopilot because before he knew it he was stepping into a hot running shower. He picked up a bar of soap and a washcloth and started scrubbing away the disgusting reminders of last night. As he scrubbed more flashes of last night came of him being helpless as he was pulled into the alley, the shot entering his bloodstream and the pain he felt from whatever had been injected into him. The more frightening the images, the harder he scrubbed which caused his skin to turn a bright pink almost red color. He didn't even notice the scolding temperature of the water or the tenderness of his skin as he continued to do more damage then good. Blood that had been crusted around his neck and hair pooled down his body and down the sink. Fresh blood also traveled down his body from his skin that he was scrubbing raw. He didn't even feel the stinging sensation on his skin. It was when the cloth slipped from his hand that he saw the blood. Greg completely forgot about the rag and watched, transfixed, as blood streamed down his arms and down the drain, mixing in with the water giving the allusion that there was more blood then there really was. He slid down the tiled wall behind him and curled in on himself, in the fetal position, and felt the water spray down into his eyes blurring his vision. But he didn't care.

After a little while of lying curled up on the floor of his shower he pulled himself together and got back to cleaning himself. He reached over and grabbed his AXE shampoo and squeezed a generous amount into the palm of his hand then gingerly started massaging it into his scalp, he moaned in pleasure from the feeling of washing his dirty hair and getting rid of even more of the blood that had crusted up there. He didn't know where all the blood came from because as far as he could tell the only injury he had was on his neck and arm but that didn't account for the rest of the blood he was slowly discovering. What did he go out and murder someone…no! He wasn't going to think like that! He was pretty sure that if he murdered someone he would have at least had a flashback of someone screaming like they do in the movies but he had experienced nothing like that beside his own attack so murder was out of the question. Then what else had happened?

When Greg was finished with his shower he turned the water off, stepped out of the shower and wrapped a towel around his waist. He walked out of the bathroom and into his bathroom to change into some clean clothes.

He changed into his favorite baggy jeans and a slim fitting long-sleeved gray and black shirt. Feeling the need to more thoroughly clean himself up he walked back into his bathroom and brushed his teeth. Just as he was reaching for the mouthwash he heard a knocking on his apartment door. Not really wanting company he decided to pretend that no one was home but then the visitor spoke. "Open up Greg! I'm trying to be civil by letting you inviting me in but I can just as easily let myself in if you do not open this door in the next ten seconds! One…two…three…"Greg recognized the voice from last night and quickly hurried down the hallway and over to the door. "Five…six…seven…"Greg unlocked the door and yanked it open to reveal the man and whom Greg assumed was his companion from last night. "Hello Greg, how are you?" Greg glared at them but wanting his questions answered allowed them to come inside. He closed the door behind them and turned to face them.

"Who are you and what the hell did you do to me?" he demanded. The man who was obviously in charge of the situation walked towards him and Greg found himself pressed up against the door in fear of what the man might do. He winched from the doorknob smashed into his back. "My name is Sean and this is my companion Toby and what you've obviously experienced is called shifting" Sean replied "shifting? I fell through a fucking wall and you acting as if this is the most normal thing in the world!" Greg said outraged "I apologize for my insincerities and for the rude way we treated you last night. I am normally a very likeable person but when our people are involved-" Greg stood up from the door "our people? What do you mean by our people?" Greg had all ready thought this guy was insane but now he had proof "yes, you see Greg in the world there is a small amount of people, around 2% I'd say, that are born with a special gene that lays dormant until activated by a little substance we like to call chemical 2113. Our people are a dying race and if we continue to allow the dormant genes to remain asleep we will slowly but surely die out in a few years time" Sean explained "and how did you know I was one of these special people?" Greg asked, "I mean for all you know that chemical could have just caused me to hallucinate. I-I…" the pain he had experienced before came back and this time he was forced to his knees clutching his head and screamed in anguish. "Toby, the package" Toby took a paper wrapped package out of his coat and handed it to Sean who swiftly ripped the package open and pulled one of the syringes out that was as long as a sharpened down pencil and was filled with a clear fluid.

Sean uncapped the shot and held down Greg's withering form and stabbed the needle into the side of his neck. Greg was in too much pain to even notice that another shot had injected something into him. Sean stood up from the floor and placed the package on Greg's coffee table. "What you are currently experiencing is your shifting gene stabilizing. Your gene is currently unstable and if you do not take these shots every seven hours for the next two weeks you could die and we wouldn't want that" Greg barely managed to make out what was being said to him but he got the gist of it: His gene was unstable and if he didn't take those shots every seven hours he would die. "We'll be in touch Greg oh and don't even think of telling anyone because there could be grave consequences" Sean and Toby walked towards the door. The pain Greg was experiencing was slowly subsiding and he watched as Sean and Toby exited his apartment. It was a few minutes later when the pain was completely gone and he stood up from the floor. On shaky legs he wobbled over, like a toddler learning how to walk, to the package and looked inside to find twelve more finger sized shots. He picked up one of the shots and examined it. 'I could go into the lab and tell Grissom that he suddenly felt better and decided to come into work' he thought as he pocketed three of the shots, grabbed his car keys and ID and left his apartment. The reason he was going into the lab was to analyze the fluid in the shots to see what had been injected into him. He walked around the back of the building and got his car out of the garage.
