It's only after the possessed professor leaves that Kyden can breathe again. His mental faculties return to him in parts and he clings onto logic even as panic, fear, and anger fester.
Think, think, think. It's all that he can afford.
Just when everything quiets, without even the distant sound of footfalls, Kyden springs into action. He sits up and pulls on his leg. The chain jingles and he tests the length of the chain.
It's not long. He can probably get out of bed and take two or three steps before he's locked in place. But from where?
Kyden leaps out of bed to check it out.
Okay, he thinks, as he inspects the chain further, it's not tied to the bed itself, but rather sinks into a small hole cut beneath the floorboard. He tugs at the chain, but not too roughly in fear of making too much noise. Nothing jostles and whatever it's connected to beneath the floor seems rather sturdy but he keeps it in mind nonetheless.
