"Katherin?" Kido knocked again, wondering if she was even awake before he was distracted by a loud noise somewhere else in the building. Did someone just slam a door? Who would do that at this hour? 

He soon received his answer as he was practically tackled to the ground by a familiar short, stressed-out Italian. "Felice! What are you doing?" The smaller boy started to panic as the other one started rolling up the sleeves of his shirt and furiously scanning his arms. "H-hey! Get off!" 

Growling, the slightly larger boy pinned him down and kept checking for any tell-tale pinpricks. He wasn't bleeding anywhere that he could see so far, but could there be anything somewhere besides his arms? Where else did people normally get shots? Did the administration here even only stick to those areas? He [i]really[/i] didn't want to think about that, but the problem was already here... 

"Stop moving! Let me see your shoulders!" He sat on the smaller boy's chest and pushed the sleeves up a bit more, still not seeing any signs of needlework yet.
