Well, they’d be trapped in that motel. Saved by Walt and Mallory, stuck waiting in a motel with their lives going nowhere unless…

Oh, wait. This is one of those times when I get an idea for an entire crossover AU.

How about we call it Brothers Lost?

He was supposed to be out there. Saving people. Hunting things.

He wasn’t supposed to be the victim. Trapped by a witch and a curse that tore his entire world away. Everything gone but Sam himself.

Send in any prompts you think of for this idea and read the little drabble I came up with below! 

I’m thinking if it gets written in its entirety, it’ll be added into the supply of AU ideas that have been written out and I’ll poll for which of these stories people want posted once A Lich of Sense is finished! (Some AU’s contain spoilers for that story)

Other AU’s created for this so far include Brothers Together and the ‘verse where a kid finds Sam before Dean. And one that no one has guessed so far. And now Brothers Lost.

“You know, you’ve done a lot of stupid things before, but this has to take the cake!”

Dean rolled his eyes and didn’t break stride. Sam had to walk faster to catch up, grumbling about his older brother’s stubborn behavior.

“Dammit, Dean. We can’t go into that room. We have no idea when that kid’s coming back. Hell, for all we know he just stepped outside to take a smoke!”

Sam finally got a hand on Dean’s shoulder, and tried to whirl him around. Dean caught his arm and used his momentum against him, sending him flying into the ground with a practiced motion. He grinned down at the frazzled Sam he was holding down. “You’re getting soft there, kiddo.”

Sam made a face and kicked up with a leg. He managed to catch Dean’s side, flipping him onto the ground in seconds. “You were saying, jackass?”

“Get off me.”

Sam helped Dean to his feet. “C’mon, let’s just head back, wait until it’s night. We can hit the room then. Walt never has to know we were here.”

Dean threw him a look. “All you do is argue with Walt! I can’t believe what I’m hearing!”

“Sure, I argue with him, but this? And for what – a slice of pie?”

Dean held out his arms. “How often do we see a slice of pie left out in a room? Hell, how often do we see it just vanish into the fridge whether they remember it or not? Sam, I’ve got to try. We might not get this chance again!”

It hurt for him to admit that, but it was sadly true for them both. Thirteen years ago, they’d gone to a motel with their dad. He was on a hunt, searching for missing children in the area.

He’d left them alone in the room.

Dean wasn’t completely sure what had happened that night. He could remember a woman, standing inside the door. The door itself bolted shut. Himself, slammed against the wall.

A flash of white hitting Sam.

Before Dean could react past the shock that covered his face, the same flash had slammed into him.

Then he was falling.

The next thing he could remember was waking up, his entire world changed. It was dark. Closed off. Two people were in the room watching over them. A woman, her blonde hair and blue eyes gentle as she helped Dean off of the stacked up fabric. She was tiny, even next to himself as a kid. In fact, Sam wasn’t far off of her height back then. He’d outgrown her in only a few years.

Mallory and Walt had tried to convince him, but he didn’t want to see the truth. He didn’t want to hear that he’d been cursed and stood under four inches tall.

He’d found Sam. They’d tried to run off into dark corridors, following dusty paths. Walt had found them in time to get them to safety. In his urgency, Dean had burst into an occupied motel room.

Occupied by giants.

Over the years they’d both come to terms with their new lives. Walt and Mallory had helped them adjust to the way things were. Finding supplies, knowing where and when to find food. All the lessons that they both needed to know to survive.

These days, Dean lived on his own. He’d found a place to make his own and had spent his time adjusting it to be livable just like Walt and Mallory had done with their own. Mallory helped him with fabrics, making up wall hangings to drape on the walls and covers for his own nest of blankets. Sam had a bed of his own back with Walt and Mallory. Dean had insisted that his younger brother use it back when they’d discovered it in abandoned motel room.

Sam came to stay with him more often than not. It didn’t feel right to be too far apart after everything they’d survived together. Dean knew that it was assumed that Sam would eventually court Krissy, but Sam was uncomfortable with the idea. There were no girls in the area that were Dean’s age, so he was left on his own.

To brood, mostly.

Which was why Sam had a habit of showing up at the worst times, trying to keep his big brother’s mind off of their situation.

Like right now, when he was trying to sneak into a room where the guest had left out a slice of pie.

I mean, who can turn down a slice of pie?

Lucky for Dean, he’s quite a bit older for Sam. He’d been living on his own for a few years when Sam caught him, and wouldn’t see Walt or Mallory right after his capture. They’d find out when he wanted to approach them with it… which with Dean, could be at any time. He’d wait long enough to be sure Sam wasn’t a threat to anyone, then go talk to them.

Sam and Walt tend to explode at each other, Dean and Walt have a mutual respect for each other. So the dynamics of the family is a lot different in either universe

Walt and Mallory Watch

Walt and Mallory are the two people that saved Sam from the witch when he was ten years old. No one knows what his fate would have been if they hadn’t been in the room during the attack.

They lost their daughter, Briella Watch, a year previous to Sam’s rescue, and in many ways her loss was what prompted his rescue. Neither of them would stand to see any more children suffer, so when Walt happened upon the witch talking in a scrying pool and getting instructions to take both brothers, they took it upon themselves to find the boys and warn them. This warning came to late to save Sam from his curse.

Years later, when Dean discovers Sam hiding in his motel room and only standing four inches tall, their home is attacked. Mallory was killed off by the demon that took away Sam and Dean’s mother Mary. Walt was lucky enough to get knocked out of the danger zone, coming to in Krissy’s home days later to discover his wife was dead and his son had abandoned him.

After a hard year, Walt’s loss is offset by the return of his daughter, Bree. Sam and Dean saved her from her captors and brought her back home. For the first time in his life, he’s discovering that humans might not all be as terrible as he thought.


  • With Walt standing at a height of 3.8 inches, this would make him Dean’s equal in height at 6′1 if they were to stand at the same height.
  • Mallory, on the other hand, is incredibly petite. At only 3 inches tall, she would come out to 4′10. She always used to say she likes her boys tall!
  • Walt is a tanner and Mallory is an expert seamstress. These skills are incredibly useful when nothing is catered to your size.
  • Before Sam and his knife, Walt would face off against rats in the motel with nothing more than his old razor. Dean would be impressed with his stubborn determination.
  • All of Sam’s clothes were fashioned by his parents, and his boots were handcrafted by Walt. They might look a little rough around the edges compared to Dean’s but they work just as well.
