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.
February 23rd excerpt:
Dean narrowed his eyes, then stalked towards Jacob’s side. “You all owe me some pie after that scare,” he griped as he started to scale up the human, digging his boots into Jacob more forcefully than normal. There was no way he was going to let Sam hang out in a hand all on his own after all that.
Jacob’s eyebrows shot up as he felt the little kicks in his side from Dean’s climb. He didn’t complain, however, letting the small hunter get his point across in his own way. Dean had been in worse moods before, after all. He kept an eye on Dean’s progress, making sure he wouldn’t accidentally knock him off balance and focusing on not twitching each time a tiny boot dug into his side.
( Things are a little slow this week because of work. Brothers Lost is under construction and the contest is in full swing. Feel free to keep sending in asks/prompts (just got an intriguing one earlier today, in fact), and I’ll reply when I can. So far this week I’ve been doing what I always do when overworked, and ordered new commissions. Best way to cheer up, imo. )
