Harry stepped up to the well worn wardrobe with a hint of fear already within him. Lupin looked contemplative as if wondering if he should simply close the class for the day, it was getting close to the time for the next period...
Harry nodded towards Lupin who sighed and opened the wardrobe and immediately the boggart escaped and blurred as it sorted through Harry's worst fears before disappearing. Gone.
Remus stared at the spot the boggart used to be before snapping off a bunch of spells and looking around in confusion.
"What did you do to the boggart Harry?" He asked, mystified.
"Nothing, it's taken the form of my worst fear. Non-existence."
