"I tell you this because I’m enhancing security measures around the castle, and the Halloween ball will no doubt be affected. I have decided it is in the best interest of the students to limit the ball to sixth, seventh, and eighth year students only. Before you protest, know that this decision was made because I believe you all to be old enough, and well-equipped, to handle any commotion at the Ball that the younger students might not be ready for. Additionally, Ms. Weasley, I would like for you to brief your Prefects. Do not share specifics, but do ask them to listen and be vigilant for any piece of information that sounds off- anything that might be concerning. Have them report it to any of the three of us immediately." Ginny merely nodded in reply, lost in thought.
