Dean actually does pretty good when he first encounters smols, so it would have gone worse than it did, but not as bad as it could. As seen in Walt’s and Jacob’s first encounters with Dean in various AUs, he’s likely to grab, disarm and then trap, likely in a vase (while Jacob would grab a coffee pot), but he’s also very methodical. He won’t hurt Sam purposely, and will keep him trapped while he figures things out. Chances are, the brothers will figure each other out long before Dean calls Bobby up for advice, and if they didn’t, Bobby would scold Dean and tell him to let the little guy go. 

Idjit.

Oh, dear! Poor Dean!

(Sam would never let him hear the end of it if he had to give up his good boots and ended up walking back to the Impala in socks)

Lucky Sam doesn’t sink into the wet cement like Dean does, so he can show Dean which way to go where the cement is hardening more. And keep out from under Dean, in case his older brother stumbles and flails when he’s trying to pull his boots out from the suction of the cement!

All in all, Dean is very lucky Sam can’t carry his cell phone around, because there would be some very compromising pictures of a normally-suave hunter.

December 29th excerpt:

“You’re too short,” Sam grumbled, leaning more of his weight on Dean than he wanted to.

“Not my fault you’re a Sasquatch!” Dean snipped. Compared to everyone else, the Winchesters were the tallest people in the room that weren’t humans, but Sam still managed to tower over him.

Thank you so much!

Dean might try to run off at first, much like Sam, but once he’s over the initial startling first impression of everything around him becoming giant, he will do his best to hide his nerves for Sam’s sake. His little brother will be fret for Dean, considering he was out cold for a week, and now he just tried to run from Sam.

As for how they’d handle it afterwards, Dean is still the older brother, and still in charge of Sam, but Sam’s going to have to learn how to defend them both. Dean will help him learn how to care for his own gun, going so far as to help Sam clean the gun. Sam’s not sure how much Dean helps, since he has to make sure to steer clear of his older brother’s tiny body, but it certainly seems to cheer him up.

Honestly, they’ll bicker just as much since Dean’s a bossy little smol, but Sam will hate if he ever accidentally startles his older brother, or god forbid, scares him.

Sam is a huge fan of chocolate of any kind, including cherry, mint and peanut butter, and Dean will pretty much eat anything candy without complaint, meaning if Sam ever tries to build up himself a stash of candy, he’ll have to defend it from Dean if he ever gets too bored.

Mine.

December 25th excerpt:

The detective groped blindly at a lock of some kind, and he focused on that. It was a combination lock, one he couldn’t simply pick open and would take far too long to figure out the code for.

“Dean,” he rumbled, eyes darting around the room. It was a wide space, nothing jumped out at him in the shapes he could make out, nothing important, anyway. “I need something to break this off.”

Dean scanned the room, all of his focus concentrated on the task. “Okay, there’s a box in the corner. It’s full of old tools, some wrenches, a pretty hefty hammer–” hefty being so big that Sam and Dean together would never budge it, “–and a drill that looks like it hasn’t been used since I lived in America. Turn right, about three steps. Watch out for the table, don’t want to go knocking that copy of Harry Potter onto the floor.”

“You’re improving,” Sherlock commented as he followed Dean’s directions. Whether it was the stress of the situation or the urgency, it certainly seemed like Dean was showing off at this point. Not that Sherlock was complaining.
