In the winter months, Sam will stick a lot closer to Dean than normal. His jacket’s very thin compared to anything Dean owns, so it doesn’t keep him warm. Not to mention, being so small, he doesn’t hold much body heat. So it’s a lot of time spent in the chest pocket. The side pockets don’t do any good keeping him warm unless Dean has his hands in them, and then it can be claustrophobic because Dean takes up all the room.

This doesn’t stop Sam from having fun in the snow. He always wanted to build his own snowman. He just has to watch out if he throws any snowballs at Dean. Dean might throw his own back. (And then have to dig Sam out from under all the snow)

Plus, sledding is awesome when you’re four inches tall. A pile of snow half Dean’s size makes a huge hill, and if he can convince Dean to help, he doesn’t have to trudge all the way back up.

In the AU where Dean saves him, terrifying. He woke up with no idea that anything had changed. The only redeeming factor was he was alone with Dean at first. It was for the best. Having John or even Bobby around would be too much for him to take. It could never be enough time to adjust, but at least Dean gave him time to take it all in before anyone started to question him.

In the actual Brothers Apart, very confusing. He woke up with Walt and Mallory watching over him, so concerned for this small boy they rescued. It wasn’t until he tried to run away from them and find his way back to his family that he discovered that they were telling him the truth. Walt had to haul him out of a motel room with a sleeping family in it, saving Sam’s ass. After that, there was no denying what had happened.

It really depends where they are. At Bobby’s, they’ll explore together. Sam even tried to venture into the wall a time or two on his own, though Dean hated having him out of sight. In a motel, they might go out for the day. Sam stays out of sight in Dean’s pocket when they’re in stores, and Dean stays away from other kids. Dean never leaves Sam alone in the motel. Even as a kid, he’s terrified that something would happen to Sam on his own.

I’m doing good, but I’m worried about Dean. He’s taking this case pretty hard, especially the fact that I’m the only one that can take Ilyana on. I know he just wants to protect me, but he needs to realize that sometimes I don’t need protecting. I need my big brother’s support.

I don’t want to do this alone.

Oh, Dean knows the first thing that’ll happen is Walt will lecture them until their ears fall off. Another part that would hold Dean back is Sean is very nervous and shy around him. A big human lecturing the teeny kid might make him scared, and that’s the last thing that Dean would ever want to do. Plus, Dean’s become good at not moving at night out of habit for when Sam’s hanging out in a pocket, so they weren’t in any danger.

John got the hell out of there. He didn’t actually know that Sam was cursed and with them until probably about a half hour into the drive. He thought that the witch had taken his youngest and was gunning for his eldest. His first thought was getting Dean the hell out of that motel and out of her reach.

Dean managed to pull himself together enough to reveal what he had cupped between his hands. Poor Sam was downsized to two and a half inches. They ended up on the side of the road when John was too shocked to keep driving.

With Sam unconscious and no way for them to wake him, they drove to Bobby’s. Dean refused to leave Sam’s side. While John and Bobby were desperately searching for a cure or a curse reversal, he was there with his brother in his hands, watching over him.

When Sam woke up a week later, he and Dean were in their own room at Bobby’s, but his bed was now too big. So Dean kept him on his chest to sleep, where he could make sure Sam was safe the entire time.

Poor Sam. He’ll have to find a way to let Dean know it’s him. Maybe he can get some of his pencil lead out of the desk and scratch out a message for Dean. It won’t be easy, but mice are crafty little guys. Sam can manage it. Dean will never let him live it down, that’s for sure. And for the next few days he’s got a mouse in his pocket, keeping Sammy safe.

Dean groaned as he read over the text. “This is boring,” he grumbled. “We should sneak out and get ice cream.”

Sam scoffed, taking a few steps on Dean’s back. He’d started out perched on Dean’s head so he could read over the assignment, but Dean spent so much of his time grumbling over the work, he was still on the same page five minutes after Sam had finished.

After being this size for a few weeks, he was beginning to find it far more intriguing than frightening. So long as their dad wasn’t yelling at them, of course. Even now, he could feel the muscles shift under his feet as Dean finally went to turn the page. He was massively outsized, but perfectly safe where he was.

“Y’know that I can’t give you all the answers,” Sam pointed out, walking back up to a shoulder so he could peer off. “You need to do some of it for yourself.”

No one had spotted Sam yet, not even during a test. He was small enough to use the folds in the shirt to hide in, and his voice was soft enough that the other students couldn’t hear him. Dean’s grades had taken an upswing, even with the course material a few years ahead of where Sam was. It was a welcome challenge that he could use to keep his mind off things.

Dean reached the end of the reading and grabbed a notebook. “Whatever. But you’re still helping me with the homework, pint-size. Can’t have you slacking off either.”

Sam hid a smirk as he swung his legs off the edge of the shoulder, letting them dangle before he dropped down to the soft mattress below. He landed in a pile, bouncing slightly before he caught his balance. From this angle, he was completely bathed in shadow from above, Dean’s shoulders blocking the light.

Making his way over to the book, he glanced up at Dean. “Do you at least have something my size to write with?”

Dean looked like a deer in headlights when he was put on the spot. He glanced between Sam, who stood all of two and a half inches tall, and the pencil in his hand, which was easily five inches, if not longer.

“Uhh…” Dean trailed off.

Sam rolled his eyes. “Looks like you’ll still be doing the work,” he jabbed.
