Professor Sprout was missing.
She did not show up in Herbology.
"Where could she be?" said Harry.
"She must be eating," said Dean.
Suddenly, there was a flash.
People looked around.
Then they saw it.
Ron had a scar on his forehead.
It was shaped like a man's face.
The scar laughed at them.
Ron screamed.
"I will be your substitute teacher today" said the scar.
The class stared at Ron's forehead.
Then they learned about bubotubers.
