Laura just stared at the Professor, if anything happened here, he did know that she would run up-to him and cling to him for dear life right, if someone had died in this room, she would refuse to come back into this room until she had spoken to the Ghost-busters to make sure that the ghost was really nice and friendly, she didn't mind having Peeves around and the house-ghost but if she saw anyone else she would freak out.

Laura decided it was time to use the spell, " Spiritum Revelio!" Laura did the ward movement and closed her eyes, she was a bit frightened was it safe or not, she slowly opened her eyes and smiled, it was safe, that was good, she didn't want to see anyone who was dead staring at her.
