Mr Rosaro thought deeply about who he should change into. If the internet was correct then this medallion could change him into another person and then after 12 hours he could change back into himself.
In his car he had some lost property. By the time he had finished cleaning the school the office he had collected an assortment of clothes found around the school. He had taken them home with the intention of dropping them into the office when he returned to the school tomorrow.
In the boys change room in the gym he had found a complete outfit, even underwear and shoes. Some boy must have forgotten to change back into his uniform after gym. Why not? Rosaro went out to the car and collected the complete outfit. He would be a teenage boy again for the night!
Mr Rosaro, grabbed the uniform and took it inside. With the door locked he grabbed the medallion and touched it to the socks.
