Castiel wandered through the streets of die Festung, visible to all and taking in the sights from as human a perspective as he could. Since he'd moved in with Dean he'd decided to try to act more like a resident of the City, instead of teleporting from outlook to outlook like he was used to. Belia and her guards could do nothing to him, really, so what was he worried about?
He noticed a few people walking around with what looked like granola bars. He paused, wondering why he hadn't seen them around before, and quickly located a vendor who was distributing them. With Dean's encouragement he'd been trying more different foods, never taking too much (since he didn't technically need it) but enjoying the experimentation.
Without asking he was handed a bar, and he looked at it. The wrapper promised energy, and that wasn't necessarily a bad thing, was it?
Walking a few steps away to avoid the crowd Castiel opened the bar and tasted the snack. It wasn't bad, and he finished the entire bar quickly, disposing of the wrapper in a nearby trash bin. He made it almost a full ten feet before an odd sensation swept over him.
For a moment he thought it might be the energy the bar promised, but before he could even really debunk that with the argument that as an angel physically he was incapable of being affected by so small an amount... something changed. He barely noticed, and all of a sudden he certainly didn't care.
He looked around, suddenly noticing a group of boys kicking around an old ball in a clearing. He hesitated just a moment, then jogged over, stopping and breathlessly watching them for a moment.
When they noticed him they stopped as well, and one of the older boys (he couldn't be much older than Cas was himself, right?), smirked. "What d'ya want, old man?" he asked. The others laughed. Cas frowned, confused. He wasn't old. Well, ok, maybe he was... but not really. Not just because of his vessel, right?
"Can... can I play?" he asked hesitantly. The initial mocking was hindering his earlier enthusiasm, and he felt nervous. What if they didn't like him? What if they didn't want him to play, thinking he was stupid or incapable or ugly somehow?
"Can you, in all that?" the boy retorted with a laugh, then turned and resumed the game. Cas blinked in confusion at the answer, and his hands went to his chest and he looked down, at the coats, the nice shirt, the tie and the shoes... everything. Why was he wearing so much?
The angel shrugged off his trench coat, then the suit jacket, pulling off his tie and then the white button up and carelessly dumping them on the ground in a pile. Now only dressed in a short sleeved undershirt, his pants, and dress shoes, the angelic youth jogged into the game, soon laughing aloud with the rest as he played keep away with the other boys.
