The head tilt wasn't too reassuring. Sam couldn't tell if the little chipmunk was tilting it's head because it was curious about his sudden presence or if it was, in fact, Dean responding to the words that had come out of his mouth. To the chipmunk's credit, however, it didn't up and run away at the sight of him walking into the bedroom, which was something that Sam was pretty sure any normal, tiny creature would have done. Squirrels and mice and things like that - they didn't exactly stick around when a human came as close as Sam was to the chipmunk now. They usually scurried off out of fear or dislike or something. Still, when Sam lowered himself to the ground, he couldn't help but frown at the sight of the chipmunk flattening himself against the floor. Whoa, was he scared? Brows knitting together uncertainly, Sam considered getting back up again so that he could clear some space between them for Dean's sake. Yet, when Dean clambered forward and began climbing up his leg, Sam went still. Okay. So this was either Dean or the bravest chipmunk in the world.
"So..." Sam looked down at him awkwardly, then shook his head uncertainly. "Uh, you're okay, right? I mean, all right, you're a chipmunk, which isn't okay at all, but..." Sam groaned. He wasn't being very helpful. "Can you nod? Shake your head? We gotta figure out some way to get this communication thing across, man." Man. Not exactly the right word to be using right now, was it? Releasing a heavy breath, Sam rubbed at the space between his eyes with his palm in frustration. "Look, I know this is bad, but I'm gonna fix it, okay? I'm gonna...I'll figure it out. I'll get Ruby and Hermione and some of the other witches here to find a way to reverse whatever happened to you." Sam looked down, eyes raking over the sight of the tiny animal that was perched on his knee. There was no way in hell that Dean was okay. He had to be terrified. Being turned into a chipmunk out of the blue, not being able to accomplish so much as opening a door on his own - it had to feel pretty damned hopeless on Dean's part. As if he needed another thing to feel hopeless about.
"You said you were hungry, right?" Sam reached into his jacket and pulled out a bag of peanuts. It was far from the most ideal food on Dean's menu, Sam was sure, but it was gonna have to make do for now. Sam didn't know what he could and couldn't feed a chipmunk yet. He'd have to do research later to make sure that Dean maintained a healthy diet while he was stuck like this - which Sam knew probably wouldn't be all too pleasing for Dean, but it was for his own good, so he'd have to deal with it - but until then, Dean was gonna have to make do with the peanuts. Sam tore the bag open and scooped up a few with a large hand. "Try these," Sam insisted, offering the peanuts to his chipmunk shaped brother. Again, Sam made a point to move carefully. He wasn't sure why Dean had seemed scared of him before, but Sam really didn't want to see him all frantic like that around him again. Chipmunk or not, the last thing in the world that Sam ever wanted was to be viewed as something terrifying by the one person in the world who's opinion mattered to him most. Dean probably wasn't behaving that way on purpose, but still. Sam didn't like it.
