July 27th excerpt:

And,” Dean continued, growing prouder, if that was possible. He lifted up his other hand, withdrawing one last item from his other jacket pocket where it had been stashed to avoid getting crumpled up with the rest of the clothing. A tiny suit dangled from his fingertips, complete with a bitty tie in Jacob’s size. Dean brandished it next to Jacob. “You can come with me when I interview people now!”

April 4th excerpt:

The fingers curled up around them as Dean put his entire hand in the pocket this time, knuckles brushing against the fabric bottom. Sam pushed a finger out of his way and Dean stretched them out, making it easy to slip down and drop to the bottom of the dark surroundings.

Once he was down, he stood and offered Jacob a hand getting down. Before Jacob could reach him, the hand started to lift away out of the pocket, Dean assuming that they were both clear of his hand. Sam didn’t need any more proof of the fact that Dean couldn’t feel Jacob on his hand at all, a concerning thought for them all.

“Dean, wait! " Sam shouted. He leapt forward, snagging a fingertip before it could raise up out of his reach.

April 2nd excerpt:

Sam stepped up next to Jacob. “Could you grab me a jacket?” he called up to his older brother. It would just waste time they needed for him to go grab one himself at this point, and he wanted to stick as close to Jacob as he could.

Dean nodded distractedly, already going over in his mind what they’d need. He snagged one of Sam’s tan jackets out of the little cloth bag of belongings, and took a second to dig the tiny, hand crafted knife out of the dirty jacket with careful, adept fingers. He handed both down to Sam while he went to get the rest of his stuff ready.

March 30th excerpt:

Jacob took a few careful steps forward, but he barely made it to Dean’s first knuckle before he stumbled and pitched forward. He tumbled head over heels onto Dean’s hand and a whuff of air rushed out of his lungs. He rolled to a stop on his back, his eyes wide and staring straight up. A few deep breaths restored his bearings, enough to realize he’d fallen right to the base of Dean’s fingers.

“Well that’s one way to do it,” he tried to play it off, but felt his cheeks heating up from the clumsy mishap.

Dean couldn’t hold in a chuckle at the abashed Jacob on his palm. As Sam grabbed his satchel, leaving his dirtied jacket behind, Dean shifted the hand a little so the flesh around Jacob was cupped, keeping him safely away from any edges as long as the fingers remained closed. It was strange to see how some of the wrinkles on his palm loomed over Jacob while he was lying flat on his back. Dean was careful not to pinch any of those tiny limbs as he shifted.

“Maybe you should let Sam give you some pointers,” Dean joked. “I think he’s the leading expert on standing on hands around here. He could even show you a thing or two about climbing.”

December 16th excerpt:

Leaning on the slight incline of John’s fingers, some of which outsized him in length, Dean had never looked smaller and more vulnerable.

This was further accentuated when a longer, paler finger came from behind John to poke at Dean’s shoulder, flipping the tiny person onto his back.

“Stop that!” John hissed, slapping Sherlock’s hand out of the way. The hand supporting Dean wavered ever so slightly, causing his head to loll to the other side.

It would certainly be an option, but I find it more than likely that they just use Dean to improve Sam’s sense of balance. Walking along a finger is like walking along a balance beam, only the skin would shift under his feet, increasing the difficulty and helping him increase his skills. A golf ball might be a bit better than a ping pong ball, since it has more heft to it. A ping pong ball might go flying when he tried to get on.

August 31st excerpt:

“I get scared a lot,” Oscar said, staring at the way his hands couldn’t cover one fingertip, even with his own fingers spread as far as they would go. “A-an’ I never came up on the beds before. I’m not very brave…”
