My first Supernatural fic that I've published. I finally finished all episodes, so I'm writing a story. This is just a little try-out story for me, nothing special. Not unless you readers make it special, that is.

Sam sat at the bar of the roadhouse while Dean and Ellen spoke about what to do. While Sam wanted to join in and help, Dean said no. After a minute of puppy dog eyes, Dean reluctantly gave him some notes about what was going on to occupy him.

Sam knew everything that was happening already, but Dean watched the wheels turn in Sam's head as he tried to put it together. He began to suck his thumb absentmindedly, though Dean decided at this moment not to say anything about it. Sam had always been a big thumb sucker when he was a kid, and didn't even quit until he was nine. Sam also kicked his legs lightly, not being able to reach the floor.

"So you say this demon turned Sam into a toddler?" Ellen asked, a bit confused on the situation.

"Not a toddler, a four–year old." Sam interrupted with a pout. Sam didn't become any less aggravated when Dean ran a hand through those curly brown locks.

"Well, how did this even happen?" Ellen asked when she began to get Sam something to drink. The now boy didn't even say anything, Dean guessed it was Mother's intuition.

She finished making a chocolate milk in a child's cup she happened to have laying around from when Jo was younger. Unfortunately for Sam, this meant that it was pink and girly. Though, since it was Ellen, he didn't complain too much.

"We think that when Sam and I got separated during the hunt that maybe this thing did this to him." Dean explained.

"But you said that he woke up like this." Ellen interjected.

"Maybe it had some sort of time for it to activate or something," Dean suggested.

"Like medicine." Sam commented.

"Exactly."

"Did you call Bobby?" Ellen asked.

"First thing I did when I saw that Sam was..well... Sammy," Dean responded. "But I wasn't sure if I should or not, and you're on the way to Bobby's, so I just went to whoever was closest, you. Sam was still asleep, so I didn't even know if he retained his memory. I was freaking out." Dean admitted.

It was rare for Dean to ever admit any feelings and emotions he had. So, of course, everyone that knew him knew that if he admitted to freaking out about something, he wasn't playing, and he was really freaking out.

"I want to be big again." Sam spoke up after drinking most of the chocolate milk from the pink sippy cup.

"We're working on it, Sam." Dean answered.

"Well, I know my way around hunting, but I don't know if I'm the person to help you. I'll do as much as I can, but I think you should go to Bobby." Ellen said.

"Yeah, that's what we'll have to do. I need some of the books he has. Come on, Sammy, let's go." Dean said. Sam immediately nodded, swinging his legs over and plopping off the bar stool because of his height difference.

While Dean inwardly laughed that his little brother was shorter than him again, all he wanted was his Sam back.

Dean walked out of the roadhouse, Sam following after him in a slight run. Dean opened the drivers door and slipped in while Sam managed to open the passenger door and climbed into the passenger seat. He would have buckled his seat belt, but there weren't any seat belts in the Impala after Sam turned eight.

"Back seat, Blues Clues." Dean said as he pointed a thumb to the back.

"Dean!" Sam whined, though didn't notice it.

"I could always ask Ellen if she still has a car seat from Jo. It'll probably be pink, Samantha." Dean smirked. Sam pouted, getting out of the seat and moving to the back seat. When he was settled, Dean began to drive.

About half an hour on the road, Sam began to squirm in the back seat. Dean noticed from the rear view mirror.

"You alright, Sammy?" Dean asked shortly after noticing. He thought maybe the kid was getting restless and wanted to stretch his legs.

"I gotta go." Sam said, his face distorted in pain.

"Go?" Dean asked.

"Go." Sam emphasized. Dean noticed that Sam was clutching himself in between his legs and trying not to whine.

"Go! Alright, I'll stop somewhere." Dean said. He groaned when he saw the nearest place that they could stop at was a McDonalds. Poor Sam would probably wet himself before he could get to the bathroom. If they didn't stop, though, Sam would do the same in the car. Looking for another place, Dean came up empty handed.

He reluctantly stopped at the restaurant, knowing he would probably wet himself in there, he decided to try and get Sam to the bathroom and hope the adult side of his baby brother would keep him from having a panic attack from the clown decorated fast food joint.

"Let's get you out of here." Dean said, getting out of the car and helping his uncomfortable brother out. Sam groaned as Dean lead him to the inside of the restaurant that happened to be decorated with everything clowns. Dean's luck was short, though, since someone in a Ronald McDonald outfit happened to be parading inside the fast food place and handing out balloon animals.

Sam unfortunately noticed the man and froze up. Dean picked him up, holding him at harms length to get the kid to the bathroom. Sam did make it inside the bathroom, though the adult side of his brain was outweighed by the physical child control. The poor kid could only hold himself in desperate need as he urinated through the small jeans that had been purchased hastily for him. Dean was unprepared for what he saw.

Yeah, when they were kids, they had to stop a lot for Sam to use the bathroom, and there were some occasional accidents. But Dean was out of practice, and mentally that was adult Sam. Mentally Sam was twenty–two–years old. He couldn't handle this.

"It's alright, Sammy," Dean comforted awkwardly. It was the only way he knew how. "I gotta see if you have more clothes out of the car, but I can't leave you here alone." Dean said. Sam only stood silently, still grabbing himself as if he were still trying to keep from wetting himself. "Do you still have to go?" Dean asked.

Sam shook his head quickly. Dean was at least grateful for that.

"Can you stay by yourself for a few minutes so I can get some clothes out of the Impala?" there was a nod. "Okay, stay." Dean said gently. He reluctantly left Sam and returned to the Impala. He went through the duffle bag of clothes that he always carried. There was a T – shirt that was long enough to cover everything Sam had, and he could pick up more clothes later.

Dean quickly collected the shirt and returned to the bathroom. Sam was exactly in the same spot as before. His eyes seemed a little red and puffy, though that was the only difference. Dean wouldn't have been surprised if Sam had been crying. It seemed like the childish side of his state would grab a hold when Sam wasn't paying attention. Sammy started crying, and Sam had to stop it. Dean knelt, helping his baby brother out of the clothes and began to help him with the T – shirt.

"Stop, Dean, I can do this by myself." Sam said. Dean stopped, not wanting to know what would happen if he upset a twenty–two–year old stuck in a four–year old body.

"Ready to go?" Dean asked once Sam was dressed. The younger nodded, so Dean took the wet clothing and walked hand in hand with Sam back to the Impala. Sam didn't even fuss about having to ride in the back this time.

Dean decided not to bring up the accident again and eventually Sam fell asleep. When Dean stopped for gas, he decided to try calling Bobby again. Usually you couldn't miss him since he was always manning the phones, and this had Dean a bit worried. Until Bobby answered, anyway.

"Hello?" came the old voice that Dean was waiting to hear.

"Bobby, it's me. I need some help." Dean said, trying to quicken the phone call before Sam would wake. Last thing he needed was for Bobby to overhear Sam. Luckily he was still asleep. Sammy had taken hold and was sucking his thumb.

"What do you need help with?" Bobby asked as if this happened all the time. Well, it did happen all the time. Dean and Sam always went to Bobby for help on a case.

"It's complicated. Sam and I are on our way to your place. Are you there?" Dean asked.

"'Course I am, you idjit. Be here in an hour, I'll make some grub." Bobby said.

"Sure thing, Bobby." Dean ended the conversation and the two hung up. Just as Dean did so, Sam began to wake up.

"Dean?" the small voice of Sam came from the car. Dean quickly fixed everything with the gas and returned to his baby brother.

"I'm here, Sammy." Dean said as he slipped back in the driver seat.

"Why are we stopped?" he asked.

"Gas," Dean answered simply. "Gotta go to the bathroom?" while Dean didn't want to remind Sam of the accident, he didn't want any repeats either. Sam shook his head and returned to his own thoughts. Dean briefly thought of playing some music, but figured Sam would probably want some quiet time for now.

The rest of the ride was silent except for the small bits of time Sammy would suck his thumb. Then there had been moments of suckling sounds before Sam realized what he was doing and quickly stopped.

The Impala pulled up into the Singer Auto Salvage yard, and the Winchester brothers immediately noticed Bobby on the porch waiting for them. Dean moved to get Sam out of the back seat when he noticed that the kid made no move on his own, seeming like he wanted the ground to swallow him.

"Come on, Sammy," Dean encouraged as he tugged lightly on Sam's bare feet. "If you don't get out on your own, you're only gonna make yourself look bad." Dean commented., and Sam did notice how Bobby was walking toward the Impala.

"Where's he hurt?" Bobby asked, walking over to help the assumed as injured child out. Whenever one of the brothers needed a place to recuperate after a sever enough injury, they went to Bobby's, who could tell who was hurt badly enough to need a place to crash by whoever was in the back seat.

"He's fine," Dean commented. He held a hand out to Sam who continued to be stubborn. "Fine, have it your way." Dean settled, lifting Sam out of the seat and holding him close to his chest. He was surprised when Sam pressed his face into his chest, though it was obviously from the kid not wanting to be seen.

"Is that Sam?" Bobby asked, instantly recognizing the curly brown hair and puppy dog eyes that no one could forget.

"Told you I needed help." was Dean's only reply. Sam continued to stay silent as Bobby lead them to the house. Once inside, Dean put Sam on the sofa. The kid gazed down at his small bare feet, obviously upset that Bobby knew about this. He reacted the same when Ellen found out, though warmed up to her rather quickly – probably because of some odd motherly force.

"What in the hell did you boys do?" Bobby asked urgently.

"We were hunting some kind of demon, we think it was something called an alp, but we don't have any information on it. Ever heard of it?" Dean asked.

"I have, they're rare, but they're out there. You went up against a monster without even having information on it?!" Bobby raised his voice. Both of the men heard a whimper and their gazes turned to Sam.

"Sorry.." Sam said quietly. He could barely control the little body and it was frustrating for him. Especially when he interrupted something his adult brain really wanted to hear with something his child body wanted to do.

"We didn't have any information on it, really. Just Dad's journal, and all it said was that there was a monster in the world called an alp. It didn't seem like he got too much info on it." Dean admitted.

"Well, according to the lore, an alp usually attacks females and drinks the blood of it's victims from their nipples," Bobby explained.

"That sounds naughty." Dean joked.

"Hush up, boy," Bobby said. "It's sort of like a sub vampire. They choose women or children, but prefer women because they like the taste of breast milk."

"So why am I little?" Sam piped up.

"Well, lore has been wrong before," Dean suggested. "Even though we're pretty sure Sam's a girl anyway." he joked.

"Shut up." Sam retorted.

"Well, maybe women or children weren't available, so it did the next best thing and used a charm or spell to turn you into a child," Bobby suggested. "My question is how you two got away from the thing. Once you get attacked by an alp, it's nearly impossible to get away. The victims lose all movement and can't move themselves until it's too late."

"Dean did it." Sam stated simply. No one would have expected any different from the older brother.

"So how do we get him back to normal?" Dean brought up. "'Cause I'm okay with him staying small and continuing to get me chicks," Dean joked. No one found it funny. "Yeah, yeah, let's go digging in some books and find out how to make you a sasquatch again." Dena became serious when Sam gave off his usual bitchface–except mini version–and Bobby looked at him with the look he always gave before he called someone an idjit.

"What am I supposed to do?" Sam asked when he wasn't given anything for research while Dean was thrown a book by Bobby.

"You can't just sit still and keep yourself occupied?" Dean asked. He had expected Sam to just be quiet anyway, since mentally he was twenty–two–years old.

"I want to help," Sam said with a pout that Dean had seen a million times from their childhood. "I can't just sit here with nothing to do." he added.

"I'll look for something to cure him. You two go eat, grub's on the table." Bobby said as he removed the book from Dean's grasp.

"Thanks, Bobby," Dean thanked, walking to the kitchen with the expectation that Sam would be following him. Well, Sam did follow him, right on his tail. "Look at this, Sammy, we've got stew." Dean said. He got himself and Sam bowls, and they sat together to eat.

Sam ate quietly, and while he found a little trouble with it, Dean didn't help him. The kid was already embarrassed enough. Dean wouldn't further that for him. Sam took longer to eat than Dean did, but Dean continued to sit with his little brother.

By the time Sam finished his eyes were drooping, Dean remembered how tired Sam would always get tired just after eating. Dean didn't say anything, instead just put the dishes in the sink and began to wash them.

He heard the cute yawn from Sam, though ignored it. When Dean finished, he walked to Sam, lifting him.

"Put me down," he whined slightly, though was ignored. "Dean." another whine erupted from him. He was pressed to Dean's chest while the older sat on the couch, reading through one of the ancient thick books that Bobby had.

Dean kept his little brother close, and eventually the protest stopped, and the sound of soft breathing filled the room. Soon sound of him sucking on his thumb followed the other noise.

"Bobby, can you watch him for a second?" Dean asked. "I need to get his old clothes out of the Impala before it starts smelling."

"Sure." Bobby said, not bothering to ask. He wasn't sure he even wanted to know.

As Dean grabbed the clothing out of the Impala, he suddenly heard a shrill childish scream. Dean recognized it as Sammy, he immediately ran back into the house to find out what could have possibly caused Sam to scream so loud he could have heard outside.

Dean found Bobby attempting to soothe the brunette. Dean took his now mini brother from the elder, holding him close.

"Sam, you need to wake up," Dean said as gently as he could with his amount of panic. "Sammy!" he resorted to shouting. The boy still would not awake. He began to shake the curly haired boy that now had tears running down his cheeks.

"He's having a night terror." Bobby informed.

"What the hell is a night terror?" Dean asked immediately. "Isn't that the same thing as a nightmare?"

"Not really," Bobby said, taking Sam from Dean so the older brother wouldn't shake him. "A night terror is something he can't wake up from. Basically we'll have to comfort him the best we can until it's over with." he explained further.

"I don't understand, why is he having a damn night terror?" Dean began to panic once more.

"It's the alp. Originally it was the explanation for night terrors, which has been used as a sign that it's coming for it's victim." Bobby said.

"Give him here, I can comfort him." Dean said. Bobby handed back the four – year old body to his brother. Sam cried and wiggled in Dean's grasp for a while–nearly two hours. Eventually when Dean began to whistle an old tune their Father would whistle, Sam began to calm.

His breaths evened out quickly and Dean made sure that he did not stop whistling that tune. When Bobby caught wind of why Sam had calmed, he brought Dean a glass of water so that he could keep whistling. The last thing they wanted was for Sam to start wailing again.
