The man's fingers flew gracefully over the keyboard of his laptop, his prized possession. He tapped each key quickly before moving into the next, each motion fluid as they had been repeated many times. He spent his very small amount of free time surfing the web for 'cases' as he and his brother called them.

The cheap hotel room door opened with a loud creak, informing the man of a new presence. "Find anything Sammy?" The new voice called.

"Dean, I've been searching for hours. I can't find anything on this Hailey Williams woman. I'm beginning to think the guy at the library was lying to us." Sam muttered, rubbing his eyes with his hands. Dean walked in and placed the bag of food he had been carrying on the table before peering over his brother's shoulder at the screen.

"It's alright, we'll keep looking. Don't stress, it's almost Halloween!" Dean cheered, walking away as he sent his brother his famous Dean Winchester smile. Sam sighed, slamming his laptop shut in exhaustion.

"That's my point, Dean. This is the perfect time for these monsters to come out of the woodwork without being noticed, but there's nothing out there! We should be dealing with some really crazy crap right now, but all we have is a vengeful spirit case!" He yelled, standing up. He towered above his older brother just as he towered above most other people at his great height of 6'4". Dean rolled his eyes as he crashed onto the couch, bacon cheeseburger in one hand and a bag of Halloween candy in another.

"I don't see the problem with it. It's quiet, that's good." The eldest Winchester shrugged, dropping a chocolate into his mouth. Sam sighed and ran a hand through his shoulder length brown hair, pacing the dusty floors.

"You don't understand. This isn't right. I just..." Sam trailed off and looked at his brother, who slowed his chewing to stare back.

"You just what, Sammy?"

"I don't think this is a vengeful spirit. Yeah it seems like it, ectoplasm at every scene, the whole deal, but something is off. I'll be back." He walked to the door, slipping his arms into his coat and snatching the car keys off of the table. Dean shot up from the couch, racing to his brother side and stealing the keys from Sam's hands.

"Whoa whoa whoa! First of all, where are you going? Second of all, you're not driving Baby!" He argued, referring to the 1967 Chevrolet Impala parked neatly outside the door in a parking space.

"I'm just going back to take another look at the victims. I've got this... Weird feeling. I'll be back, and yes I am taking the Impala. You can come with me if you want, but there is something wrong here. That purse you said was always in the room of the murders?" Sam held his EMF scanner over the supposedly haunted purse, and nothing happened. The lights stayed off, the device stayed silent. "Nothing. Now come with me or stay here, I don't care. If you come with me though, you can drive!" He bribed with a grin. Dean shoved him out the door before following with a low grumble, grabbing the large bag of Halloween candy on his way out.

"Whatever let's just go and get back, it's the day before Halloween and I want to celebrate." Sam gave his brother a strange look before responding.

"Celebrate as in eat candy until you either puke or pass out?" Dean smirked as he climbed into the driver's seat of his beloved car.

"Don't forget drinking!"

"How could I forget..." Sam scoffed sarcastically and hopped into the passenger's seat. The drive to the hospital was short, and filled with the sounds of AC/DC blasting through the speakers.

"YOU SHOOK ME ALL NIGHT LONG!" Dean sang along as they pulled up to the hospital. Sam rolled his eyes jokingly, opening the door and stepping out of the car. He made it to the door in a few strides, Dean following suit. He reached his hand out, yanking the hospital's glass door open and stepping inside. The harsh disinfectant smell reached their noses, Dean crinkling his in disgust. No matter how many hospitals they visit, he never gets used to the smell of chemicals, and his eyes still watered and stung.

"Agent Tyler, this is my partner Agent Perry. We were here earlier for the recent murders." Sam informed the receptionist. The brothers pulled out their fake IDs and she nodded lazily. They walked back to the morgue and found no one inside, luckily. The two let themselves in and Dean pulled out the container marked with the name of the latest victim. The sight was surprising, even to him.

"Sam... Maybe you were right..." He whispered in shock. There was now a large hole in the man's chest, and an empty space where his heart once was. Sam whistled in surprise.

"Werewolf?"

"This is one smart mutt though. Waits until after the autopsy to collect its prize." The eldest Winchester commented, sliding the box back into the wall. "I'm sad to say you're right Sammy. Only issue is, we have no leads."

Sam shook his head. "Maybe we do."

The two approached the house of Henry Johnson, the local librarian. Each had a gun loaded with silver bullets in the back of their pants, and a silver knife freshly sharpened.

"The night before Halloween and we're hunting real monsters." Dean muttered, carefully picking the lock on the front door. It unlocked with a click, and he opened the door. The house was pitch black, the air heavy with stressful silence. "Let's just gank this puppy and go home."

"When you say it like that, it sounds kinda demonic." Sam pointed out.

"Why yes it does, especially when I am in no way a puppy." A deep voice sounded from next to them. The brothers snapped their heads to the side, eyes wide. A dark chuckle emitted from the darkness which slowly changed into a low growl. The Winchesters took a step back as two glowing yellow eyes peered at them, the only thing visible in the darkness. The werewolf howled tauntingly before rushing at them.

Dean attempted to fire at it, but he missed every shot. The shorter brother tried to step backwards, but he was quickly tripped by an electrical cord which caused him to fall onto his back. His life flashed before his eyes as he saw the yellow eyes growing nearer each second. He rolled out of the way of the immediate danger, hearing the wolf-man creature fall to the ground with a thump and a snarl. Dean stood up quickly, reaching his hand out and walking until he grabbed his brother's arm. He didn't want to lose him, it was his responsibility to look after him. Dean would rather die than let Sam be hurt.

Sam came to a sudden realization as he stared into the fierce yellow eyes of their attacker. He had seen eyes like these. They obviously weren't the same eyes, but they made him furious nonetheless. Those eyes filled his nightmares, taunted him since he was only six months old. He felt his breathing become ragged with rage, and the grip on his knife tightened.

"HOW DARE YOU!" He bellowed, rushing forward. He felt Dean grab onto his jacket and quickly maneuvered out of his brother's grip. The werewolf stood, ready to attack. Sure he was faster and sure he was smarter, but that doesn't trump a man taking revenge for his dead mother. Sam knew this wasn't the same creature, it wasn't even the same species. The yellow eyed demon that had killed his mother in front of him had been dead for years now, but that didn't matter. He still managed to plunge the knife straight into the creature's heart, backing away as it slumped to the ground, taking it's final breaths before laying still.

Sam took a moment to catch up on his breathing, evening it out. Dean finally felt around the walls, flipping the lights on and staring at Sam and the wolf in shock. "Holy crap dude..." He whispered. "What was all that about?"

Sam simply shook his head. "Nothing. Nothing at all." Dean wasn't convinced in the least, but he didn't question his brother. At least, not right now.

Three hours later and they were finally driving home. It was two AM, and they were both ready to get some rest before looking for another case the next day. The Impala pulled up to the motel and Dean parked it before turning it off and getting out of the car. The brothers went from being on the verge of sleep to fully alert and guns drawn in a few seconds as they noticed the light in their room was on.

"I turned it off when we left..." Sam muttered, slowly approaching and unlocking the door. Dean threw the door open, pointing his gun in front of him.

"Cas?" He called to the trench-coated fallen angel on the couch. Castiel groaned, clutching his aching stomach. Around him lay about 150 empty candy wrappers.

"Did you eat all of these?!" Sam asked, raising his voice in surprise as he gestured to the wrappers. Cas only looked up with a pain filled expression and nodded.

"Yes... And now I- I have this strange feeling in my stomach... It is not pleasant... Am I dying?" His face turned panicked and his breathing came in quicker, shorter breaths. Dean sighed and sat next to him, placing a hand on his back comfortingly. Sam chuckled, beginning to clean up after the 'baby in a trench coat'.

"Cas, you're not dying. You're fine. It's just that you're human now, you can't eat this much. You've got a stomach ache now. You'll be alright, what does your stomach feel like?" Dean informed softly.

"It feels as if the food is forcing it's way back up and out of my stomach..." Only now did Dean notice the green tint to his best friend's face, and he quickly rushed him to the bathroom, letting him vomit into the toilet.

Sam finished cleaning, trying to block out the disgusting noises of Castiel puking as he lay down on his bed. He put his arms behind his head and closed his eyes.

"Happy Halloween everybody..."
