If we take your two guesses we can splice together the title of the next fic in Brothers Unexpected! A Place for Oz (which happens to be Dean’s pocket more often than not XD), continues on the adventure for the smolest kiddo with his irascible giant and his even-more irascible father!
Suddenly all of Oscar's questions for Dean were far from his mind. The current situation held his focus.
He was in a car.
All his life, creeping through the dark vents and spaces between motel room walls, Oscar had never imagined what it'd be like. He could actually feel the motion, faint vibrations as the car hurtled along far faster than he could fathom. Even the turns didn't slow down enough for him to keep up. The sounds and the feelings rattled his miniscule body and Oscar was stuck between fascinated and scared.
He kept a corner of his cloth pinched in his fingers, rubbing the worn threads with a thumb. Oscar was very good at staying hidden, and if Dean didn't know he was there, he might not even notice the tiny weight in his pocket. No one looking at the teen would see more than a fold in the fabric. Oscar took a slow breath in, and then let it all out in a huff. He was safe, and he just needed to remind his nerves of the fact.
After some time curled up in his blanket with little change from the outside of the pocket, he shifted at last. Curiosity crept in and nagged at him. This was the first time he'd really left home, and he was missing it. That thought enabled him to let go of his blanket and push it to the corner of the pocket while he grasped at the flannel weave instead.
(tagging @kajensen07 and @torchmlp since I had to screenshot the guesses instead of answer directly to keep them together)
