Dean's nature of being a total fuckboy had it's consequences every now and then, and one of those consequences was you. Not that he didn't love you or anything, he did, he just kinda didn't know what to do when he caught wind of the fact that he had a 16 year old child.

There was a miniature Dean walking the Earth somewhere, and he needed to meet them.

He and Sam ended up taking you in after some complicated stuff with your mom, and Sam was your designated babysitter after Dean caught you blackout-drunk sleeping on the library floor.

Dean was out running some errands that he said would probably take a day and a half, so that left you and Sam in the bunker. Normally you stayed locked in your room or literally hiding in a corner of the library somewhere, and Sam did give you your space. Though, he did check in every now and then to make sure you were alive and well and not drunk.

He knew you liked reading, so he'd bought a bunch of classics and found you in your corner, where he set them down and sat across from you, a few feet away.

"Got you these, uh." Sam looked around for a second, a little awkward as to what to say. "Do you want a pillow or something? I don't think it's good for your back to sit like that."
