Though I adore all the AUs, I’d be lying if I didn’t say I had a favorite. Brothers Lost is irresistible, from the fact that both brothers are tiny to the way Dean is a tiny rumpled innocent when it comes to drinking! It has new and fresh interactions and a ton of story ideas! Tiny Dean is my personal fave (though I do love tol Dean as well).
I, too, have a favorite, though it’s a very close race. I think Brothers Found just barely wins out against Brothers Adopted for me. I love tiny Jacob, but tol Jacob is how he’s really meant to be. He’s such a gentle giant and he tries so hard to make sure little Sam is at ease around him (as I’m sure you’ll start to see as the chapters unfold in Chasing Family).
