Mr Spiff heard about Zero's special condition from the dean. He could understand why. The kid wasn't particularly strong looking and would probably be the target of bullying. Kids these days weren't the nicest, not that he expected anything less from demons. However, Zero just struck him as the odd one. The compliments he dished out weren't full of sarcasm, malice or ulterior motive. As a mirror demon, Spiff had the ability to look into a person's heart and reflect their true nature back at them. Zero's true nature blinded the professor.
"That was awesome!" Zero's voice could be heard again just as another student finished their round. His excitement was attracting odd attention within the class but Spiff simply couldn't stop him.
