Caleb

Caleb is in a mental facility because he is a psychopath. He has a history of being violent with everyone he encounters. He has a cold demeanor, that added onto his violent tendencies, scares the staff working at the facility. You work at the facility as whatever you want, it is your first day and you were checking on how things worked, getting used to the layout, etc. when you pass his room to see him restrained on all four of his limbs.
