One night, after a particularly tricky dealing with some demons, the boys don't feel quite right but not bad or ill enough to worry themselves with it. Little did they know everything was about to change…

Sam threw his duffel bag in one of the beds and placed his laptop on the table. He sighed. "Ugh, man! I'm gonna hit the shower."

"Don't use all the hot water!" Dean yelled at his brother before taking the empty bed and turning on the TV.

Sam waved his hand "Yeah, yeah." He closed the door and started undressing. He looked in the mirror; he admitted he didn't look good but it had been tough with these demons so he dismissed it and relaxed under the hot water. After 10 minutes he stepped out drying his hair with a towel.

Outside Dean had turned off the TV as he found nothing interesting on it and he took out his guns and cleaning set entertaining himself with the task at hand

"Hey!" Sam said as he sat next to his brother. "I was thinking... You wanna grab a bite?"

"Yeah, I'm starving. I think I saw a diner down the road." putting his disassembled guns aside Dean stood from his place on the bed. "Finish those while I take a quick shower, will ya Sammy? Then we'll go get some grub." The shorter Winchester said as he walked into the bathroom.

Sam thought about their case meanwhile he disassembled the guns. It had been easy. Just your average demonic possession by lower rank demons. But then again, it hadn't. He had felt like there was something off about the whole thing but he hadn't mentioned it to Dean. Maybe he was just being paranoid. His stomach made a grumbling sound that pulled him out of his thoughts. "C'mon Dean! You're taking forever!"

"Compared to you princess of flawless hair?" Dean commented sarcastically walking into the room. "'M ready let's go."

Sam smiled. "Shut up." They drove around until they parked in front of the diner. Once inside they sat down and Sam tapped his fingers until a waitress greeted them. "Hi guys! My name's Sally and I'll be your waitress! What can I get you?"

"Steak, a big one medium rare." The answer rolled out from Dean's mouth almost instantly, he barely spared a glance at the enthusiastic girl who looked a bit disappointed.

"Same for me" Sam said just as quickly.

"So... It'll be two big steaks medium rare?"

Sam nodded.

"Right away." Sally said smiling.

"Since when does Buggs Bunny eats meat?" Dean looked at his brother quizzically.

Sam was gazing out the window. He turned to look at his brother. "What? I don't know... I just got a craving that's all." He cleared his throat.

Dean hummed distractedly. "It's just odd seeing you eating man food." They didn't have to wait long until their steaks arrived, a juicy rib eye was placed before each Winchester and they stared with hunger at them before setting themselves up to devouring their scarcely cooked meal.

"Odd's an understatement." thought Sam as he ate. When they were finished, the waitress returned.

"Wow, you guys were really hungry" she said. Sam smiled awkwardly.

"It was a really long day" He thought about ordering another one to go but thought better about it and didn't say anything. "You ready to go?"

"Nope. Say sweetheart, Sally right?" The girl nodded. "Any chance Sally, that you've got pie for dessert?" Dean asked half flirting with the waitress. Sam rolled his eyes at his brother's attempt to pick up the waitress.

"Sure! We've got apple pie, lemon pie, strudel, chocolate mousse with a ball of vanilla ice cream, cheesecake, strawberries with cream. Chocolate, vanilla and strawberry milkshakes..."

All of this dessert talking was making Sam dizzy. He cut her off right there. "Apple pie will be just fine, thanks."

She wrote it in his little notebook "Absolutely! You want to accompany it with something? Coffee, milk, tea?" Sam ordered coffee just to stop her from babbling all the different existing types of teas in America.

"Ok Samantha, what's got your panties on a twist?" Sam was distressed about something and he was not being subtle about it, Dean noticed. "Your sudden meat craving made you ill?"

"No, shut up!" Sam said defensively. "I just... I wanna go back to the motel, that's all."

When the waitress brought their things, Sam took a sip of his coffee. "Might as well give it a shot" "Hey Dean, have you noticed anything unusual since we came back?"

"Weird, huh?" Dean thought of it for a second, he actually had being feeling odd, kind of uncomfortable with his own skin but finding no reason for it he dismissed it. "Nope I don't think so. You getting the flu or something?" Sam waited nervously for Dean's answer.

"Yeah, maybe that's all it is. Now that you mention it, my throat feels a little itchy." But that wasn't it. It wasn't at all. "Well at least he doesn't suspect of the demon blood." He didn't say anything after that and finished his coffee wishing Dean would hurry up so they didn't have to stay in the diner any longer.

They didn't speak further, Dean left the money for their food on the table and walked out of the diner, Sam hot on his hills. Dean drove Baby back to the motel not commenting on Sam's obvious nervousness. "Home sweet home."

"Yay." Sam said softly, opening the door and entering hurriedly. He locked himself on the bathroom and gripped the sink, hyperventilating. "Okay Sam, calm down. Calm the fuck down, okay? Breath, breath... In and out, in and out." Sam's breathing slowed down. "That's it. Good job." He looked at the mirror but what he saw wasn't him or at least, couldn't be. "Hello there, little monster. Aww you don't look so well, do you?' It said. 'Ahhh but nothing a little demon blood can't fix." The creature took a knife and cut his wrist. Black blood started pouring from the wound and the thing drew his arm closer, offering the substance. Sam looked back at the door.

"B-But Dean..." The creature scoffed, "Dean? What does he know? He's been back 3 months and he suspects nothing! That idiot doesn't have a clue. Don't worry... He'll never know. Come on, just a little. You want it! You /need/ it! You're not strong enough and you know it!" Sam looked away.

"Shut up" he said quietly. "Shut up?" The creature laughed. "Shut up?! You can't shut me down Sam. It doesn't matter how much you try. I am you!"

"No, you're not! I'll never be like you!" Sam screamed. "I'm not a monster" he said more softly.

"HA! Even you don't believe that! You've known it all your life! You're a freak! You can't fight it, so you might as well accept it." Sam fell to the floor and started shivering.

"Please, stop it. I-I'll do it" he stammered. "J-Just stop it." He took out the little silver bottle and drank as the thing watched from the mirror with a wicked smile on his face.

"That's it, buddy. All the way down." He encouraged. Sam whimpered but kept drinking.

As soon as he finished, he felt a pounding on his head, like a million war drums were inside his head. He closed his eyes and felt for the light switch until he found it and turned the lights off. He slowly opened his eyes and looked at the mirror again. The creature was gone and he looked awful. He wiped the tears from his eyes and brushed his teeth as many times as it took to wash the blood off. After making sure he looked 'normal' again he unlocked the door and walked to his bed without looking at Dean.

"I'm gonna hit the sack" he said as he tried to steady his voice.

"You sure you're ok?" Sam only nodded turning around facing away from him. Dean sighed.

"Ok." He turned off the light deciding he needed to rest as well. As soon as he closed his eyes the nightmares started.

"Hello Dean, how did you like my little illusion?" Alastair grinned wickedly at the human strapped once again to its rack. "You believed it didn't you? That you are upstairs, that Sam's alive? You hunting together again? My most ingenious plan I must say." The demon rose his eyebrows mockingly.

"No! That's a lie! You promised me! You swore that if I took your razor, you'd never torture me again!" The demon just laughed.

"Dean you've never heard? Demons lie. Castiel is an illusion, and you think Lilith would have left Sam alive? You are a pathetic little boy trying to be a man trying to save everyone. You never got out! You never will!"

"NOOOOOO!" Dean woke up screaming, he was covered in sweat. The clock marked 3:45 he listened for Sam's breathing to make sure he didn't wake him, and thank Chuck he didn't. Dean laid back on his bed waiting for the breaking dawn.

It had been a dreamless night. Sam felt jumpy after all the blood he had drunk last night but tried his best to hide it. He still felt a little pounding on his head but it wasn't as bad as it had been last night. He scratched his head and felt two bumps.

"Hmm... What the hell?" He must have hit his head yesterday with the sink or something. He didn't remember. When he turned around he found Dean was already up. "Since when do you get up so early?" He yawned.

"Couldn't sleep." the response was dry and emotionless, the lack of sleep present in his voice. "Being doing some research, I think I've got us a case in Washington, six drained bodies all with strange bites, local PD says that it was wolves." Sam was only half listening.

"Huh? Oh yeah, yeah" he stretched. "I'll grab my stuff and think I'll be ready in what half an hour?" His stomach growled. There was that meat craving again.

"Yeah I'll go grab breakfast and make a short trip to the drug store I've got a nasty headache and we're out of aspirins, anything you'd like?" Dean answered standing to get dressed.

"Uh, yeah, thanks. Can you get me a salad please and some aspirin would be nice too." He stood up and went to the bathroom. "See you in a bit."

Dean took the keys from the nightstand and went out to get a cup of black coffee, their food and the much needed pain relieving drug.

Inside the bathroom, Sam picked up a towel and covered the mirror with it. He showered as fast as possible, not wanting to spend another minute in that bathroom. He stepped out and dried his hair only to find that it got stuck on his head.

"What the hell?" He went inside again and to his dismay took the towel off of the mirror. Sam gasped and almost tripped with the damp floor. He looked horrified at himself as he touched with trembling fingers the horns that were sticking out of his head.

"No, no, no, no! What is this?!" They weren't very big yet but they were definitely obvious and they twisted backwards in a macabre way. He ran quickly to his bag, he had nothing to cover himself with. He never packed any hats. "Shit, shit, shit" He found an old bandana and tied it around his head.

"This'll have to do. I don't even want to think what Dean will do when he sees this." He sat down in the corner of the room and waited for Dean.

Still parking in front of the pharmacy, Dean downed two aspirins with a sip of cheap whiskey. He passed a hand through his hair in an ineffective attempt to lighten the pain cursing through his head.

"What…?!" He was taken aback when he sensed something hard between his dirty blond sticky-upy hair, moving the hair out of the way he found a golden horn on the right side of his head inspecting it on the mirror it was small and tender to the touch. Searching the other side of his head he found a twin horn symmetrically opposite. "...the Hell?"

"Exactly Dean, the Hell I told you I'd never let you go." Dean heard Alastair's haunting voice.

"No! No! NO! I don't believe you!" The last sentence was but a whisper. Dean turned away from the mirror and drove as fast as he could to the motel. Getting out of the car with the things he had bought, he ruffled his hair to hide his new additions from his brother, once he was satisfied he opened the door of their room at the 'Pink Flamingos' motel.

Sam heard the door open but didn't move. Until he heard Dean's shuffling steps, he took a deep breath and got to his feet. He approached the plastic bag and took out his salad.

"Thanks." he whispered, not meeting Dean's gaze. He moved to his bed and started packing his clothes and his laptop. "I'm ready, you want me to wait in the car?"

"Ok..." Sam probably didn't hear him as he bolted out of the room. Dean shrugged and picked up his stuff throwing everything into his duffel bag. He went to the restroom and staring at the mirror he made sure once again that the horns were not visible through his messy hair. "I hope they don't grow any longer, Sam would be disgusted with me if he found out, and this time he'll leave me for sure." Dean found his brother sitting on the car as he walked out, he threw his bag in the trunk preparing mentally for a long drive.

"What up with the head band?" Dean finally asked turning down the music to make sure Sam heard him.

"What? This?" Sam pointed to the red bandana. "You don't like it? It's my new look" He tried to joke but tension was palpable in the car and Sam had to resist every urge not to jump from it. Anyways, it didn't work. It just earned him an awkward silence and a weird look from Dean. So he opened his salad and started eating. God! How did he managed to survive this long with only salads? He wished he had a steak right now or demon blood- No, wait. What?! Look what it did to you! You're turning into a demon! Sam thought.

"But you like the way it makes you feel don't you?" A little voice in his head said. "You need it. You can escape it!"

"Wow, if you're my conscience you are doing a hell of job!" Sam sighed. This wasn't going anywhere.

"So... About this case you mentioned earlier... The bodies were drained? But no organs missing? Could be werewolf?"

"Maybe." Dean shook his head at his brother's antics. "But it could also be a rugaru or a wendigo gone nuts." The conversation flowed casually. "Act normal, if you act ok he won't notice you're not." He encouraged himself.

"Umm... Yeah..." It was getting hard to think. Sam felt lightheaded. He shook his head and then leaned it against the seat, closing his eyes. "What's happening to me?" He thought with panic. "You are going to have to tell Dean, sometime. You owe him at least, that." Sam thought about his father. What would he say if he could see him? Nothing, maybe. He would probably shoot him on the spot. "No, that would be too easy." He would probably torture him. Make him suffer? "That's what I would do." Sam spared Dean a quick glance. Dean would resist the temptation of the demon blood with no second thought. He was a lot stronger than Sam. God, Dean! Did he think Sam was a monster? He had convinced himself that his brother was still human. But now? "Now you've done it, Winchester. Congratulations." His father's voice quickly found its way to his thoughts. "You're not a Winchester. You're not my son. You're not even human." Sam turned his body to face the car's door and closed his eyes.

Dean drove while humming with the music, but even when he looked calm and collected his thoughts were chaos. "Cas was supposed to save me, to cure me! And now I'm becoming a fucking demon…again!" Dean was furious at the angel and scared of what Sam would do if after all he did become one of the monsters they hated the most and hunted eagerly.

Sam slept all the way. Everything was easier when he was unconscious. He woke up with Dean shaking him slightly. He opened his eyes slowly. The sun was setting on the horizon. "We're there?"

"Not yet, still a few miles to go. But I'm starving and I bet you could do with something to eat." Dean explained pulling over in front of a small restaurant.

"Oh" Sam rubbed his eyes. "Yeah, I'm up, I'm up." He stretched as much as he could inside the car. Just as he stepped off, did he realize the excruciating pain on his back. Sam bit back a whimper and groaned instead, rolling his eyes. *What now?* Nevertheless, he followed Dean to the restaurant.

Dean asked for a double cheese burger meat half rare and a beer. Never looking at the waitress, instead trying to figure if Sam was all right by staring at him.

Sam ordered a salad again, completely ignoring what his stomach truly wanted. As the pain of his back intensified, he ran out, leaving a totally suspicious Dean, more suspicious than ever. He ran into the woods behind the restaurant until he couldn't run anymore. He fell to his knees. His back felt like it was on fire. He couldn't see but he felt like his very bones were trying to rip through his flesh. He couldn't handle another second until he literally clawed at his back with nails that had grown two inches long. He suddenly froze when he saw that two black bat-like wings had sprouted out of his back. They were covered in slime and goo from liquids Sam didn't dare think of. He curled up into a ball and started shivering. "No, no, no, no..."

Dean ran after his brother. "SAM!" The forest and he was dark. "SAMMY!" Pain assaulted him suddenly running from the bottom of his spine to base of the neck extending over his shoulder blades. It became a dull throbbing as he put it aside and kept running in the direction he last saw his brother disappear. "SAMMY! Answer me dammit!" In his distress Dean never noticed how his nails became claws or how his teeth became sharper, his canines becoming more like fangs, he felt his shirt getting damp but he didn't feel the spikes coming out of his backbones one per vertebrae all curved downwards. "SAM!" He tried to listen harder for any signal that could lead him to his baby brother.

He heard Dean's shouts for him from afar. Terrified, Sam crawled to the nearest bundle of trees and hid, his wings dragging limply behind him. He sat leaning against a tree trunk and maneuvered his wings to make a cocoon around his body. He hugged his legs and leaned his head on his knees. "Please don't find me. Not like this."

Dean heard a rustle of leaves and turned to walk that way. "Sam?" He saw something move in the darkness, it was big and unlike anything he'd ever seen huge bat like wings held tightly covering the form beneath. "Sammy?" Wings shuffled again trying to fade into the shadows, any doubt he had of 'it' being his brother disappeared that second. "Hey Sam, buddy, 's okay man." Dean moved closer, Sam was shivering, the eldest hunter stretched out to touch one of the strong wings, they were covered in blood and some kind of slime.

Sam jumped when he felt Dean touch one of his wings. He tried to run away but in his hurry, he got tangled with his wings and fell. He tried to crawl away. *Pathetic*

At last when he saw there was no escape, he turned, but didn't look at Dean. He opened his mouth to say something, anything, but no words came out.

"Sam, calm down! It's okay, it's just me." Hands up showing he meant no harm Dean tried to approach his brother again. He was close to Sam when he fell to his knees his hands flew to his head holding the base of his horns, he let out a pained scream as he felt how the additions grew thicker and longer.

At last, Sam looked at Dean. "Dean!"

Any and all coments are apreciated by me and my co-writer sorry for the mistakes it's late :$
