Remus smiled proudly at the boy before turning his attention back to the rest of the
class and instructing them on how to use the particular charm to fight off the creature
inside the wardrobe. When they all seemed to have it down quite well, he brought Neville
to the front of the class and grinned when the boy confessed his deepest fear was Snape.
Remus felt determined to rid the young wizard of his phobia.
"I would like all of you to take a moment now to think of the thing that scares you
most and imagine how you might force it to look comical.. ." He remembered his own
lesson back when Professor Prewett introduced the class to their first boggart, and a part
of him began worrying that this was a very bad idea. Certainly, there would be the typical
fears of spiders, rats, and maybe a goblin or two, but Remus was suddenly worried that
deep down there might be a few students who—like himself, Sirius, Mia, and James—had
darker fears.
Already, he could see Harry looking uneasy, and guilt settled in his stomach like
cement.
A glance to the side showed that Hermione appeared nervous as well. Remus had
never had the chance to see Mia's boggart, but she informed him and Sirius that it was
visions of them telling her that they hated her, something he could not possibly imagine.
Certainly, a young Hermione Granger would not have the same fear.
It was Harry that worried him. When the boy had mentioned someone screaming
when faced with the dementor, Remus had assumed the voice to have been Lily's. That
thought, paired with an approaching boggart, had him terrified that Harry's biggest fear
would be reliving the death of his parents. It was something Remus could not bring himself
to witness. He would certainly have to intervene.
A giant spider, six feet tall and covered in hair, was advancing on Ron, clicking its
pincers menacingly.
"Riddikulus!" Ron bellowed, and the spider's legs vanished; it rolled over and over.
Lavender Brown squealed and ran out of its way, and it came to a halt at Harry's feet. He
raised his wand, ready, but Remus hurried forward, jumping in front of him.
"Here!"
Crack!
The legless spider vanished and in its place, a silvery-white orb hung in the air in
front of Remus. "Riddikulus!"
