Version 4
3yo Sam

"What the..." Dean said in surprise as a bright white light appeared in the bunker.

A familiar-looking small boy with light brown hair that is curled towards the end appeared in their midst.

"Huh?" He uttered in confusion at the sudden and instant change in environment. Then, his eyes focus on the two other beings in the room while they stare back. His heartbeat picks up after the shock wore off and he began to register the strange surrounding that he just fell into, and the two humongous strangers in front of him.

"Hey.. it's ok, we're not bad guys..." Dean tried to reassure as he recognises the fear forming in his eyes, while slowly getting up from his seat.

However, before he could speak another word, the boy turned towards the opening that leads to the back of the bunker and bolted.

"No, no, no, wait!" Dean exclaimed as both he and Sam run after the run-away.

"... Dean!.. Daad! Deean!..." They can hear him screaming in a frantic, high-pitched voice, along with the pitter-patter of his tiny feet scurrying along the bunker's corridors.

"... Deean!.. Where are you?!" He yelled with tears in his voice.

"Dude, I'm right here," Dean muttered to themselves before signalling for Sam to go the other way to intercept young Sam.

Seconds later, Sam is trapped at a corner by the two adults, his eyes wide with fear, and they're rapidly accumulating tears.

"Hey, hey, it's ok... It's Sam, right? Sam Winchester?" Dean said to the child, whose fearful expression changes slightly to surprise. He paused for a moment before nodding quietly to confirm Dean's claim.

"Right... yea, you see, er, your dad, John, he left you with us.. cause he got some work to do," Dean bends down to his height, "He says he'll come and get you when he's done so, you can relax, alright? We're not bad guys.. we're friends of your dad," Dean quickly made up something to calm the frightened kid, speaking in a deliberate, slow manner so that he can understand.

Sam listened carefully as Dean spoke and a little dent appeared between his brows. He doesn't remember dad leaving him with these two strangers... In fact, he distinctly remembered being in a motel apartment with his brother while his father left for work.

"... Where's Dean?" He asked in a small voice.

"Dean? Er..." Dean rolls his eyes to the side as he thinks of a follow-up story.

"My big brother," Sam informed him, misinterpreting his pause.

"Yea... yea I know," Dean said airily.

"He's with your dad. He needed him to help out with something," Sam spoke up and Sam turns his attention to the taller man. The dents between his eyes deepened.

"... I was just with Dean. Dad said we can't leave the room," Sam said in confusion.

"You were sleeping like a baby when your dad handed you over. You must have been dreaming," Dean told him.

Sam still looks a little muddled but he has calmed down much and those tears managed to stay put in his hazel doe eyes.

"Hey, Sammy? Let's go back to the library, alright? Are you hungry? The... Jim," Dean nodded at Sam, "can make us some peanut butter and banana sandwich, how 'bout that? Your dad said you like that stuff," he added to prove to him again that they knew of his father.

Sam thought about it for a second and then nodded in agreement.

"Great! Come on, let's go," Dean straightened up and held out his hand towards him. The little one took a few steps forward but shifts his hand to his back.

"Ok... this way," Dean let his hand falls and guides Sam towards the library with the kid trailing along 2 steps behind. Meanwhile, Sam heads to the kitchen to make sandwiches for himself.

"Where's Dean?" Sam asked again as Dean helps him to a chair.

"We told you, he's helping out your dad," Dean said patiently.

"Help how?" He asked in detail.

"I dunno... run some errands probably," Dean answered vaguely and grab a chair next to Sam.

"I can go with Dean. I can help too," Sam chirped.

"Yea.. no.. Uh, Dean can do it himself," he explained.

"Hey, what's up?" He went on to ask when Sammy's face fell into a sad frown.

"... Does Dean not want to bring me along?" He asked with a sad little pout.

"What?... No! Why would you think that?" Dean said in exasperation.

Sam casts his gaze down as he plays with his fingers.

"... I ate all the Lucky Charms.. Dean hasn't had any," he admitted guiltily.

"Ah..." Dean said. The reason is more minute than he has expected.

"Hey, don't worry, he's not mad at you for er, eating all the Lucky Charms," Dean reassured him.

"Really?" Sam peers up at him hopefully with his wide, innocent eyes.

"Yea, of course," Dean confirmed and Sam's expression lightened up a little.

Just then, Sam returns from the kitchen with a plate full of sandwiches.

"Here, eat up," he placed it right in front of Sam, who leans towards it temptingly but seems hesitant to touch.

"Don't worry Sammy, there's no poison in here," Dean joked as he picks up a piece and stuffs it in his mouth. Sam takes one for himself too. He has made enough for all three of them. Finally, Sam followed their example, took a piece of his favourite snack and began nibbling at it.

As Sam eats, the two adults went a bit further away to discuss the situation. They decided on calling Cas for help while doing whatever research they can in the bunker.

"You done eating?" Sam was going to get some drinks from the kitchen when he noticed one last piece of sandwich left on the plate.

Sam nodded at him, and he reaches out to take the plate back to the kitchen. To his surprise, Sam pulls it away from him.

"You still want it?" Sam asked with a quizzical look.

"... It's for Dean," Sam mumbled and a corner of Dean's lips lifted at his words.

"Oh. Er.. there's more at the back, we can make more for him later if he wants any," Sam told him and he nodded and relinquishes the plate to let Sam take it away.

Sam sits in his chair with nothing to do, now that he has finished his snack. He glances around the bunker with interest, especially at the library of books stacked up against the shelves. Then, he noticed Dean looking at him when their eyes accidentally met, and he quickly cast his gaze down.

"Hey, what were you doing before you got here?" Dean asked conversationally.

Sam looks up at him timidly and he opens his mouth, then he stops himself at the last moment, remembering something, and closes it again.

"Yea?" Dean prompted and Sam said while looking down at the table, "I'm not supposed to talk to strangers..."

"Whoa, but, we're not strangers. I'm Rob. And that's Jim, and we know your dad. You don't remember it, but we've met when you were younger.. younger," Dean told him.

"We have?" Sam blinks innocently.

"Yea, I fed you, washed you, played games with you..." Dean went down the list. "Anyway.. So, what were you doing before?" Dean asked.

"I was with Dean. Dad just went out. Dean and I watching TV," Sam said.

"What were you guys watching?" Dean asked.

"Scooby-Doo!" Sam said with some enthusiasm.

"Ooh, I love that show!" Dean enthused back, making Sam smile.

Sam returns to find Dean and young Sam conversing animatedly about their childhood cartoon show.

"... Daphne is my favourite, she's hot.. pretty," Dean said.

"Oh! Dean likes her too!" Sam told him, and Sam lets out a chuckle.

"Your taste in girls hasn't changed much," Sam commented to Dean in a low volume while Dean snorted dismissively.

After that, Dean and Sam continue their research while they play Scooby episodes for Sam on a tablet.

Castiel arrives at the bunker half an hour later.

"Cas, hey, this is -"

"Sam, from 1986," Cas gave an x-ray look at the child, who shrank lower down in his seat. "Hello, young Sam, it's nice to meet you," Cas said, but Sam merely peers up at him shyly with his lips sealed tight.

"Er, yea, he's uh, "Not supposed to talk to strangers"," Dean told Cas and then he turns to Sam. "It's ok, he's with us, you can talk to him." And Sam looks from Dean to Cas.

Cas smiled gently at the kid and offers him his hand. Sam stares down at it for a second, then, he raises his own hand to give it a quick high-five.

"There you go..." Dean said as he carelessly messes up Sam's hair.

Sam, Dean and Cas then discuss what they'll do and then Cas left the bunker with the promise to find Liutprand's counter-spell. The two remaining adults continue with their research while Sam returns his attention to Scooby-Doo.

Two hours or so later, Sam starts to fidget in his seat.

"When is dad comin' fetch me?" He asked and the other two look up from their books.

"Soon. He'll be here soon," Sam told him.

"How soon?" He isn't satisfied with the vague answer.

"Er... 5 hours tops," Dean came up with a random number.

"Ok... Is Dean coming with him?" He asked.

"Probably... Why?" Both Sam and Dean are curious about the reason behind that query.

"He can have the peanut-banana sandwich if he comes," Sam explained and a look of comprehension came over the two. He still feels sorry for the Lucky Charms incidence and wants to share his favourite food with his brother. "Can you tell dad to bring Dean with him?" He requested.

The two of them exchange a look before Sam pulls out his phone.

"Yea... sure, you can uh, leave him a message..." Sam said as he goes into the recorder app and held it towards Sam. "You can say what you want to da.. your dad into this and he'll listen to it when he's free," Sam elaborated when little Sam just stares at the machine blankly.

Sammy raises both hands tentatively to pull the phone closer to his face.

"Dad?..." He said into the phone, looking up at Sam with uncertainty while Sam nodded at him encouragingly.

"Dad, it's Sammy..." Sam began. Dean smirk at the older Sam and the latter rolled his eyes at him.

"... When are you coming? .. I ate peanut-banana sandwich and watched Scooby-Doo! .. Bring Dean here when you come fetch me, ok? There's some more yummy sandwich! Ok, dad?" He paused afterwards and Sam retrieved the phone to play back the recorder for him to hear.

"He'll call back when he gets the message," Sam told him and then keeps the phone back inside his pocket.

Sam went back to watching the screen while the other two continue with research. He spoke out once or twice, checking if dad called, and of course, he didn't.

More time passes and Sam begins to doze off in his seat.

"Come on, let's get you to bed," Dean walks over and picks him up before he falls off his chair.

"Hmm..." Sam tightened his arms around Dean's neck as he lays his head on his shoulder, eyes never opening once throughout.

"Dad..?" He called out in a mumbled voice.

"Shh… You'll see him soon," Dean murmured back as a promise. The two adults bring the child into Sam's room and Dean carefully lets him down on the bed while Sam covers him with his blanket.

"Mn… Dean..?" He called out next as he rolls over in bed and Dean gave a start before leaning over and placing a palm on his chest.

"I'm right here," he whispered into his ear reassuringly, patting him softly as he coaches him to sleep. Sam looks at Dean with widened eyes and raised eyebrows, not expecting him to reveal his identity. Luckily, Sammy doesn't seem to notice as he is already too far gone in his sleep.

Despite so, somehow, young Sam does seem more relax after that and quickly settles into a deeper slumber without another word. Dean slowly gets up from the bedside and gestures for Sam to follow him out of the room.

"What?" Sam exclaimed when he noticed Dean staring at him in a way.

"Dude, just what did we feed you that turned you from that - to this?" He jabs his thumb at the recently shut door and then waves his hand up and down at the large man in front of him.

"Shut up," Sam snorted with a smile.

They then return to the library and their research materials, with Castiel showing up a couple hours later, having gotten the counter-spell.

"Sammy… Sammy… Hey, buddy, wake up, you can go back now," Dean lightly shakes the sleeping child.

"Hmm?..." Sam raises a fist to rub at his drowsy eyes.

"Here… I got you…" Dean easily lifted him off the bed and carried him over to the library.

Sam recited the counter-spell and a bright portal appears in the middle of the room.

"You'll return to your space-time once you step inside the portal," Cas told young Sam, who is squinting at the dazzling portal with some apprehension. Dean lets him down on his feet.

"Go on," he prompted, giving him a little push on the back. Sam stumbles forward, and then stands still on the spot.

"You have to walk through it, kid," Dean told him. Sam turns his head to look pleadingly at the three adults, with fear in his eyes.

"You'll see your dad and your brother once you go to the other side," Sam encouraged.

"Dad and Dean are inside?" He repeated. "Daad~? Deean~?" He yelled at the portal, making the rest of them smile.

"They can't hear you, you have to go in," Sam said.

Sammy nodded and walks towards Dean, reaching for his hand.

"No.. Sorry, Sammy, you have to go on your own," Dean pushed his hands down gently.

"You're not coming?" Sam asked with a pout. Dean gets down on one knee to meet him at eye level.

"… I'll see you on the other side," or, at least, one version of him will so he isn't exactly lying, "Go," he spun him around to face the light.

Sam walks tentatively towards it till he's just a step away. He tilts his head back to look at the three, who smiled and nodded encouragingly at him. One last step, and he is completely engulfed by the light, which then disappeared in a heartbeat, together with Sam.

~ The End ~

I considered only writing the version where both young Sam and Dean appears tgt cause that's the most interesting version in my head~ But in the end, I still decided to have the versions where they appear individually too, like what I've originally planned~
