near a small , cabin-like janitor room , there were cameras were different than the ones you saw at schools and hospitals and much more akin to the ones youd see in secret spy movies : that model was activated by heat , so i could use my skill to pass through unnoticed if i used that area , which would help in case i needed an alibi in the future for i could just say i was still at school while some sort of disaster happened , that is , if i failed .
