Cute guess! Kinda the opposite of Brothers Asunder, but with a fluttering Bowman. He’s only five in the story, so they’d have their hands full with a wee little sprite that likes to just run off when he gets excited.

This isn’t the AU, but it’s a fun idea to muse on!

This is a cute idea, but it’s more likely to appear as a story within one of the AUs, it won’t be an AU on its own. Can you just see how offended Sam will be if he wakes up in a room full of normal-sized furniture? He’d be yelling at Dean for pranking him in a dollhouse!

This is actually an idea we’ve been kicking around for a future story, but so far we haven’t had any huge strokes of inspiration for it (or any ideas for a name). Sam, the much calmer tol, with tiny zen Jacob and Dean the angriest smol to ever smol. Perhaps one day that will be the one you’re guessing!

(Honestly, these guessing games give us so many new ideas, so keep ‘em coming!)

And I will forever imagine Dean storming the table if Sam manages to catch Jacob… just going in guns blazing (or at least his bitty knife). That’s his adopted little brother. Give back.

Now all I can see is a wee baby Sammy getting cursed to be small! That poor kiddo, not knowing he has a big brother out there and Dean growing up completely on his own. It’s hard enough on Dean to lose Sam when he’s ten, here he’d spend his entire life without him.

Nope, this won’t be the mystery AU, but it’s certainly a sad idea.

Oh, what’s that I hear? A new AU?

Brothers Unexpected? What could this possibly be about?

Why the new AU you ask?

Well… because

We just can’t get enough of this! So, if you’ve got any ideas what this is about, send in an ask and maybe you’ll be the lucky person who gets everyone a sneak peek.
