Wednesday 15th September 1971
The next morning James and Sirius could barely contain their excitement and hurried their dorm mates down to breakfast before any of the other Gryffindors. They were the first students to reach the great hall, other than a few Ravenclaws bent over their NEWT revision books with huge mugs of black coffee.
"Perfect," Sirius beamed at the empty benches, "Front row seats!"
"Bet no one shows up for hours." Peter groaned, half asleep, propped up on his elbows.
"Oh cheer up," James poured them all large mugs of tea, "Don't want to see the fruits of our labour?"
"Not at six in the morning." Peter replied, slurping his tea. Sirius winced at the sound and pushed a plate towards him,
"Have some toast and stop whinging."
Remus took some toast too and cut it into four pieces. He spread marmalade onto one quarter, jam onto another, butter on the third and lemon curd on the last. He ignored the look of amusement Sirius was giving him. Remus had never had so much choice before, and was determined to make the most of every meal.
Fortunately, they did not have to wait too long before the other students began to trickle in for breakfast. The first Slytherins arrived just as Remus was finishing his toast. Three boys and two girls; third years. They walked over to their table, quite unaware of the four eager Gryffindors watching them intently. For a few moments it was as if nothing was different. Sirius sighed with disappointment. But then. The tallest boy shuffled slightly in his seat, rubbing his arm. Another seemed to be looking for something in his pocket, but from Remus' viewpoint he was clearly scratching his leg furiously. The third kept using his wand to rub behind his ear.
"It worked!" James whispered, breathless with excitement. Even Peter looked cheerful now.
As more and more Slytherins filtered in, their problem became more obvious – and more hilarious. By seven o'clock the Slytherin table was full of squirming, writhing, scratching boys, and horrified looking girls. Amycus Carrow, a burley sixth year, eventually ripped off his robes, his school jumper and even his tie to claw at his chest which Remus could see was already red raw. He almost felt sorry for them.
But then Snape came in. Whether it was karma or sheer luck, Severus seemed to have reacted particularly badly to the rosehip seeds. He walked in with his head bowed, hair falling over his face, but his nose was still visible and clearly bright red.
"Oh Merlin!" Sirius wheezed, laughing so hard he was holding his stomach. "Tell me we got his face!"
"Oi, Snivellus!" James yelled out, suddenly, to get the other boy's attention.
Snape spun around, looking up; his hair parted. The left side of his face was covered in an angry red rash, from his temples all the way down to his neck, disappearing under his uniform. His left eye was red too, the lid swollen and irritated.
"Looking good!" Sirius crowed, and all four boys dissolved into giggles as Snape stormed out of the room.
By the time breakfast was over, the entire castle was buzzing with rumours about what exactly had come over the Slytherin boys. Sirius and James looked as though all of their Christmases had come at once, and even Peter had cheered up remarkably – reminding them all that he had kept lookout, after all, making the entire venture possible.
"It was all Lupin's idea, though," Sirius returned, slapping Remus heartily on the back, "What shall we do to celebrate, eh? Exploding snap? Raid the kitchens?"
Remus shook Sirius off, smiling politely.
"Well, whatever you do, you're doing it without me," he replied, "I've got double detention."
