July 14th excerpt:

“Riiiight,” Walt said slowly, pulling away from Dean’s neck once they were clear. “I… don’t think I’ll ever get used to this.”

“The crazy’s only just begun,” Dean muttered under his breath, and received an instant jab in the neck from Sam for his troubles.

When a witch made him small as a figurine
Now he’s stuck in the dark, a world unseen
(He’s gotta be a smol, ‘cause he’s Jacob Andris)

It’s a lot of hard work, but you can’t just quit
He and Sam livin’ large in spite of it
Since that great big flash when everything just changed
and their molecules got all rearranged

Is that what you were going for, anon? XD

July 13th excerpt:

Lunch took half an hour, and Dean spent most of that time patiently scanning the world outside the Impala. He couldn’t stomach the thought of food, so he fiddled with the paper bag the sandwich had come from, hoping maybe Sam would think he’d eaten a second sandwich. Maybe he’d been too distracted to listen to Dean order, or–

“Really?”

Dean lost all hope of sliding this one past Sam when he heard the disapproving tone in the soft voice down on the seat. He turned his eyes down to where Sam was standing with his arms crossed, right next to the parted foil wrapper of the sandwich. Clearly, he knew Dean had never ordered more food. Not that Dean had held out much hope of slipping it by Sam. He never could.

With a wan smile, Dean gave it his best shot. “I just figured you might want seconds,” he said in a half-hearted protest, waving the food off.

If you mean teddy sized to some humans (like a foot tall or thereabouts), for both Bobby Loran and Chase Lisong, I think the first reaction would be something like “What the fuck, dude.”

Chase would tease, but he’d be more likely to notice that Jacob is freaked out and try to also focus on getting him back to normal. Y’know, still messing with him here and there but also recognizing that it’s kinda scary.

Bobby would probably tease him a lot more. Pushing the little guy around in his fascination over the change. None of them are really used to Jacob not being the biggest and strongest of the group. Bobby might get a little carried away, but Chase would step in to tell him off before long.

If you mean extra smol Jacob (teddy sized to little guys like Sam), Jacob would have to really hope no one’s first reaction is to grab. It’s way too easy to accidentally hurt him at that size.
