Definitely AU from the others—by the by, Albus is in Slytherin for this chapter! That'll help explain a bit later on.
Prompt: "Hazard"
No one was ever sure who gave James, Albus, and Fred the idea for "the Greatest Prank EVER", (Lily would guess Roxanne), but suffice to say, no one else saw it coming. Certainly the teachers didn't, because if they had, they would have never let the three boys flood every classroom in the entire school with unmelting snow. At least Professor Flitwick was impressed by the charms they used—that didn't stop them from being forced to shovel out the snow, the muggle way even, for punishment though.
But many of the students didn't mind at all—with all the class rooms blocked, (and many a teacher's class notes lost within), there was little the teachers could do, but declare a snow day. In the middle of a rather hot week in April.
Lily didn't mind, neither did Hugo, who sportingly joined Rose and their brothers and/or cousins as they worked to shovel the snow out the windows.
"You know, I'd like to know how long this took you guys to cook up," Lily mused, transfiguring a soggy notebook into a bowl to scope out some of the snow with. "Is this edible by the way?"
"Sure," James answered before dumping a large shovelful out the window. "S'nothing wrong with it. I'm not sure if it'd digest well though, not melting and all."
Lily considered it for a minute then chucked the snow out the window too. Why risk the chance?
"You know," Albus grumbled. "You could do something useful."
Hugo grinned, hopping up on a desk that Rose had finished drying the snow off of. "Like how?"
"Grab a bloody shovel, what do you think?" Albus huffed.
"I believe the saying goes 'you did the crime, now do the time'?" Rose smirked, leaning up next to her brother as Lily joined them.
"Where did you hear that?" James asked curiously (he and Fred were in much better moods then Albus).
"A book," Rose answered unsurprisingly.
"Well, I say a little shovelling is worth it. Did you see the look on Professor Patil's face when that avalanche fell out of her room onto her?" Fred snickered.
"You're lucky she didn't get hurt," Rose quipped.
"A little snow never hurt anyone," Albus insisted.
"How do you guys plan to dig out all the rooms anyway?" Lily asked, grabbing some more snow with her bowl to dump.
"It'll melt at midnight," Albus explained. "I tried to tell Professor Sprout that, but she said a little good old fashioned shovelling wouldn't kill us."
Lily couldn't help but to agree with the headmistress—it might be the only thing that would teach them a lesson.
"I," Fred announced, setting his shovel aside for a moment, "am famished."
"When is that little menace of a friend of yours coming, Al?" James asked, also pausing. "You said he'd have lunch brought up to us in a bit."
"You guys aren't making him carry a bunch of food up to you by himself, are you?" Lily scowled.
"Roxy and Louis are helping him," Rose told her calmly, then frowned. "Or, at least they were supposed to." The others paused uneasily at the severe look on her face—for Roxanne and Louis's sakes, they had better be helping.
Turns out they didn't have to wait long before Scorpius, (and Roxanne and Louis), brought them some food, nicked from the kitchens. James and Scorpius had their customary stand-off moment before Lily pointedly interrupted them by coughing. Still glaring at her eldest brother, Scorpius joined her at her side before helping hand out the food.
"We tried to get as much as we could," Louis remarked, quite cheerful for his bit of mischief making.
"And we tried for a good variety," Roxanne added, handing out a thermos of warm soup.
After a brief lunch—they couldn't dally long since Professor Longbottom and Hagrid repeatedly checked in on them to make sure they were still working. They managed to clear out two and a half class rooms before their professors finally took pity on them, and called it time served. James, Albus, and Fred complained all the way to the Hospital Wing about the throbbing sores and welts they now had on their hands.
"I don't suppose that's really going to stop them though," Lily mused to Scorpius as they walked down to the where the Slytherin dungeon and Hufflepuff cellar were, leaving Rose to go to the Ravenclaw tower, and Hugo and Roxanne to the Gryffindor tower.
"Detention's never stopped them before," Scorpius agreed. "Although, I must admit, I did like a day off."
"You know," Lily began, stopping in the middle of a hallway, "there's just one thing that bothers me about this."
Scorpius paused, looking back to his girlfriend. "And what's that?"
Lily frowned. "What's going to happen to the snow when it all melts?"
"…it'll probably just vanish." He grinned at her. "I mean, at least I hope Albus at least is smart enough to realize that all the water would just end up with us in the dungeons."
Lily giggled. "It would serve him right, if all his stuff got soaked."
They two shared a chuckle as they headed for the staircase leading downwards. As they went, they both paused.
"Do you hear that?" Scorpius asked, frowning as they looked around.
"It sounds…like a roar," Lily commented as she tried to pinpoint the noise.
"Or maybe even…" Scorpius went pale as they looked down the hall. "Rushing water."
Every classroom's door in the hall they were in began to bulge outward then explode, releasing waves of water out at them. They both screamed and ran as the water rushed towards them. Soon, water from the upper floors joined the rush, and they were engulfed.
Lily grabbed a hold of Scorpius's hand as they were pulled along. Thankfully, the water spread out as the corridor opened into the stair, and slowed enough for them to grab onto the banister. Both of them spluttered as the water rushed past them. As they clung to the banister, both watch with wide eyes as Peeves, riding a desk like an impromptu surf board, went down the cascades of water, cackling madly. Far below them, they heard shrieks rising up undoubtedly from the Slytherin and Hufflepuff common rooms.
"I," Scorpius coughed as the water slowed. "Am going to kill your brother!"
"Fine! I'll just kill the other one myself," Lily seethed.
