Luna Lovegood

Res made his way out of the library and saw a cute blonde in the hallway.

She was not in the typical Hogwarts uniform, but due to his position as an Overseer, Res knew she was a student at the school, a Ravenclaw by the name of Luna Lovegood.

He approached her. "Why aren't you in uniform?"

Luna sniffed as she gave him a once-over. "If you must know, all students that are 18 can go to a school dance..."

Res put her into a trance.
