Cassandra's eyes widened. The Headmistress? She's at the door? Her mind was racing now. This meant that she really was locked in the classroom, this wasn't a test afterall. Cassandra began to breathe faster and faster, panicking silently. Her face was flushing and it was getting harder to breathe. She sat perfectly still, looking at her professor who was still at the door, hoping he would unlock the door soon.
