He sat that night in his small room reading packets of paper by candlelight he wished came from a wand.
"It's Your Chance to Do Magic, Too!" screamed one title. "You Don't Have to be A Squib!" another packet proclaimed. Beneath the big, flashy titles were lists of herbs to eat and wand movements to practice, besides advice on how to procure the wands and other magic supplies illegally.
And to the light of the candle he that he wished was light from a wand he practiced.
"...10 minutes after eating the tzrat you should begin to feel light. When you start feeling this try the swish and flick movement. Remember-start with a light object and only when you master that move on to a heavier object!"
All Filch felt was itchy and when he looked he4 had white spots covering his underarms. He snuck into the Hospital Wing, Mrs. Norris at his heels and looked through the healing books, trying to find a cure, but Madam Pomfrey came out before he could read through a full page.
"Just seeing if there's anything wrong, Madam. Thought I heard a noise," he muttered and tried to slink away.
Madam Pomfrey glared at him and then caught sight of the white spots which had by now crept down to his hands. As she rubbed gritty-feeling lotion on the spots she muttered to herself about liabilities.
Soon Filch was creeping back to his room, holding a candle he wished was a wand.
