For @dakt37 who wanted a fic about deaged! sam and Jack. Not sure if the ending makes sense, so please tell me if it does
Jack looked down at the little boy who a few hours ago was the tall towering Sam that he knew, now he was 4-years-old and barely reached up to his knee. He could hardly believe that a boy still small would grow up to be the giant known as Sam Winchester.
“Hey, Sam” he said quietly, the same way Sam had spoken when they first met
“where’s D’n?” Sam whispered, not moving from where he was hiding behind a banister in the library
“he’s not here at the moment, but he’ll be back soon. He left me in charge” Jack responded patiently. Dean and Cas were currently out hunting the witch who had done this to Sam, but before he left Dean had made it clear that this version of Sam didn’t know about the hunting world yet, so Jack had to be careful with what he said
Sam peeked out his little head a little more and Jack had to bite down his tongue to stop himself from squealing. Dean wasn’t kidding, Sam was one heck of a cute kid. “who ‘r you?”
“my name’s Jack, and I’m a friend of your brother” Sam peeked out a little more before stepping out from behind the banister
“when D’n back?” it took a while for Jack to decipher the 4-year-old’s words, ‘it’s funny’ he thought, how much Sam had changed since he was four, but then he figured everyone was like this.
“he’ll be back soon, he told me to keep an eye on you”
“k. I’m hungree Jac’” Sam said and lifted his arms in the air,
“what would you like to eat?”
“Lucky Charms!” Sam declared happily and Jack froze,
“what was that?”he asked, barely able to believe what he just heard
“lucky charms!...plueeze?” Sam added, remembering his manners
“sure! To the kitchen!” Jack said and led the way with Sam following him like a lost puppy, Jack smiled as he thought about older Sam and what he would think about having unhealthy cereal for dinner. He laughed about the differences between his Sam and little Sam.
“you ok, mister?” Sam asked from where he was trying to keep up with Jack’s long strides, another thing he had to get used to. Usually it was the other way around.
“I’m fine Sam” Jack replied, giving him a warm smile which he returned, Jack was glad to know that at least one trait about the Sam he knew was still there. His big heart.
A few hours later, both Dean and Cas returned to the bunker to find Sam sleeping against Jack by the table with empty bowls of Lucky Charms and Crunch Cookie Crunch in front of them.
“hey!” Jack whispered, being careful not to wake Sam up “did you kill the witch?”
“yeah we did, but it’ll still be a while before Sam will be back to normal” Cas replied as he took the empty cereal bowls to the sink to wash
“so, you kids have fun?” Dean asked and took a seat across from Jack, who nodded happily
“yeah! We decided to mix our cereals together, and then we both got a sugar rush. Well, Sam did. Not so much me. Anyways, we ran around the bunker before coming back here where he collapsed. How come you never told me your brother was this much fun?”
“yeah, Sam outgrew this phase a long time ago. He decided to eat more healthy when he was 10, major killblow, but hey. What can you do about it?” Dean replied as he got a beer and handed one to Cas who had just joined them
“also, you weren’t kidding about his puppy eye look. He is very cute” Jack said slowly and Dean’s grin grew
“I told you. Yeah, Sam was a pretty cute kid.”
“speaking of which, I think we should get him to his bed” Cas said as Sam shifted against Jack slightly, Dean nodded and gently picked his brother up before leaving the kitchen
“you did a very good job Jack” Cas said once dean had left
“thanks, I now know what it’s like to care for someone. Why Dean tries so hard to protect his brother. I’ve only looked after Sam for a few hours, but I already feel more protective of him. Is that normal?”
“nah, that’s just what I call the Sam effect” Dean said as he re-entered the room and took a sip of his beer
“the Sam effect?”
“yeah, its like Sam has this thing that makes everyone he meets want to protect him. I saw a few cold-hearted hunters warm up slightly whenever Sam was present.”
“and you believe it?” Cas sounded sceptical
“well it worked on Bobby” Dean said and Cas nodded, Jack who made met the Bobby from the alternate universe understood. Bobby had a tough exterior around him that made him seem cold-hearted, but Jack could bet that within 5 minutes of meeting little Sam, that heart had warmed up.
“anyways” Dean said as he finished his beer “we should head to bed” he stood up and walked out of the room with Jack and Cas following.
The next morning, Sam woke up with memory of yesterday, except he had a craving for Lucky Charms.
