Prompt 16 - Weapon
@wolfstarmicrofic May 16, word count 473
“Your wand is a useful tool,” their Defence Against the Dark Arts professor droned on. “But it can also be a deadly weapon, so it must be used wisely. Remember that,” he added, eyeing a certain group of four sitting at the back of the class.
“What on earth can he be insinuating?” Sirius said in mock outrage.
“You know, I do believe he thinks we can’t be trusted with our own wands,” James replied.
“Abundantly rude, I say!”
“Quite.”
And then they proceeded to cast low-level hexes at each other.
They continued, unnoticed by the professor, getting more daring by the minute until one of Sirius’s spells went awry and hit Remus in the hand.
Huge pus-filled boils erupted across his hand. He ground his teeth to keep from crying out in pain.
“Oh, shit, Remus, I’m so sorry,” Sirius gasped, putting his wand away and trying to help. The only thing he managed to do was pop one of the boils. Pus leaked from Remus’s hand and blobbed onto the table. Remus glared at it and, while the professor was still distracted by his lesson, he slipped his wand into his uninjured hand and hissed under his breath. “Waddiwasi.”
The glob of stinking pus on the table shot into the air and straight up Sirius’s left nostril.
“UGH!!!” He retched, trying to blow the foul stuff from his nose.
“Is there a problem, Mr Black?” The professor asked sternly.
“N-no, Professor,” Sirius gagged.
“Then sit back down.”
Sirius dropped into his seat and, in between bouts of retching, transfigured his ink pot into a pot of pepper, upturned it into his nose and began to sniffle.
“AH—AH—AHCHOOOOOOO!!!” He finally sneezed, spraying the back of Snape's head with a mixture of snot and pus. “Oh, sorry, Snivellus,” he sniffed before sneezing again. Snape sat ram-rod straight as the pus and snot dripped off his hair and onto the floor, his jaw clenched tight, but he didn’t turn around.
Sirius sneezed for the rest of the class. He got so bad that James had to cast a muffling charm around them. Class ended, and Sirius all but ran from the room, Severus Snape charging after him.
“You can’t hide from me, Black. I can hear you sneezing!”
“You going to the hospital wing?” James asked, pointing at Remus’s throbbing hand.
“Nah,” he said, shaking his head. “Bit of Murtlap essence, and it’ll be good as new.”
“Can’t say the same for Sirius,” Peter said, pointing at the blur running past them, sneezing repeatedly.
“How the fuck do you get out of here?!” He wailed as Snape continued to chase him.
“Might learn a lesson?” Remus scoffed.
“I doubt it,” Peter snorted, and the three of them burst into laughter, hurrying towards Gryffindor Tower in case Snape turned his ire on them.
