Yosuke yelped, and immediately felt bad about it. Trust him to get so wrapped up in getting the hell out of the way that he couldn't notice when he wasn't. Maybe part of him hadn't woken up yet. "S-Sorry," he mumbled, the apology spilling out on reflex before he even glances round. "It's just, if they're all busy renovating in there, I figured it's best not to get under their feet..."

When he did look towards the stranger's voice, he immediately felt less bad. That... wasn't a costume, was it? Or else it had to be the most convincing one he'd ever stumbled across. Once he'd stared for a fraction of a second too long to remain polite, he could see the vertebrae. Along with a lot more than he cared for. And if it was one thing to watch a skeleton burst into existence from a safe distance away knowing that his best friend had the reins (handlebars? ... shoulders?), it was another to encounter one all but privately snickering at him while he was stranded on his own.

If he was here, said best friend would probably take this in stride, too. With that in mind, Yosuke made a valiant effort. He sagged, still propped up against the wall, but stopped short of screaming and running away. "I... guess I'm still a little on edge," he said, helplessly.
