Mannequin

He could sense me somehow.  How?  It had been reckless of me to assume that he used sight to get by, especially when he didn’t have eyeholes in his mask.  The fact that he hadn’t noticed I was faking meant he wasn’t relying on sight, or his sight was limited enough that he couldn’t make out the lack of blood through the cloud of bugs around us.  If he wasn’t hearing my breathing, I doubted he had super hearing either.

Did he use radar, like Cricket?  It would be my first assumption, except my bugs hadn’t heard anything of the sort.

Could that be a clue as to how he sensed the world around him?  Heat?  Or was it something completely different?  Radiation?  Radio waves?  Electromagnetics?
