Tricks are for kids!

The discovery of the 'Come and Go room' was perhaps larger than the Philosopher's Stone, at least in Harry's opinion. A treasury of lost things from objects belonging in a museum, to a music box a student's dead mother left them.

Harry had only spent a couple hours looking but that alone was enough to determine a few things. First, any currency such as Galleons was taken somewhere else, presumably as a 'donation' to the school.

Any 'cursed' objects were also taken somewhere else, he suspected the House Elves either destroyed them or took them directly to Dumbledore. A shame, but only the most dangerous cursed objects seemed to be removed, as he'd found many prank items that'd been 'Overloaded' for lack of a better word. For instance, a paint bomb that had enough force to blow your hands off.

In the end he'd put Blitzy to work finding his valuables, it should be pretty easy given that not enough time had passed that it'd be buried already. The Imp knew the consequences should his valuables remain missing for an extended period of time.

"Harry?" Hermione started, she and the other members of her house stared at him as he takes a seat beside her, "Is something wrong...?"

"What do you mean?" he casually asks, playing dumb as he looks over the students at the Slytherin table. The incubation period of the worms had come, and he didn't want to be anywhere near those affected once they ingested food...

Malfoy and his company were looking pale and slightly gaunt as if they'd not been eating enough for weeks, or months. The worms had been sucking out the calories and nutrients they needed, steadily growing inside them.

"You've never come to sit with me before... What's changed?" Hermione continues, "A-are they bothering you, the Slytherins?" she asks with a furrowed brow.

"Says something doesn't it? Even the snakes don't like him." Ron snickers nearby, but Harry ignores it and shakes his head at her, "I've just got a feeling something bad's about to happen."

"Something bad?"

Harry leans forward on the table and steeples his fingers, glaring at the Slytherin table. "Something bad."

"Me thinks Harrykins' has got something cooking up, brother of mine." one of the Weasley brothers remarks, sliding into the space next to Harry.

"To think such a distinguished member of society would stoop to something as low as..." the other twin forces himself between Harry and Hermione, the latter reluctantly taking her plate and making room with a huff.

""A prank!"" both exclaim, leaning closer to Harry with expectant expressions.

Harry sighs and dismissively waves his hand at them, causing the one on his right to float up and drop into the other's lap. The duo laughs at this, and Hermione yelps as she suddenly slides closer, stopping inches from Harry on the seat. "I'm not like you, pranksters pull stunts to have fun. There's no fun to be had here." he states, just as a commotion erupts at the Slytherin table.

"Malfoy, what are you doi-" Daphne Greengrass angrily stands but pauses as her target collapses stomach-first onto the table, hacking and gagging. "S-someone get Madam Pomfrey! He's-" she's interrupted once again as Crabbe and Goyle slump over, then Pansy Parkinson, Millicent Bulstrode, and many other Slytherin students.

A chain reaction runs down the table, but only affects certain individuals, most of the unaffected back away, and the rest soon follow once others start spewing their guts.

Snape rushes over with his wand drawn, thinking this to be a curse or poison of some kind, but he too quickly gains distance when the students start vomiting long, writhing white lines, they looked like fleshy, rotten, spaghetti pasta, an inch or two in diameter at the largest, but their length was the most disgusting thing about them.

So long were they that Malfoy couldn't vomit them up in one go, leaving long dangling strands hanging from his throat and mouth. The students couldn't even scream since their throats and mouths were blocked, too busy wrenching and coughing up whatever they could.

"God, what in the bloody hell is that!?"

"I-I've seen this! T-they're worms! Tape worms!" Padma exclaims from the Ravenclaw table, her face pale as she shoves her plate away and throws up, hoping whatever eggs they might have eaten haven't latched.

This, of course, causes everyone else to do the same... Huffle Puff, Ravenclaw, Slytherin, Gryffindor... The only people who weren't trying to vomit up their breakfast were the teachers, some of the older students, and the few people around Harry...

"H-Harry... You're my hero..." one of the Weasley twins heatedly whispers.

"AAAGGHHH!" Malfoy screams as he loses control of his bowels, dropping his pants and spraying a line of shit across the floor, that too riddled with parasites.

"Legendary..." the other twin grins almost manically.

"W-what did you do...?" Hermione sputters is shock and disgust.

"Me? Nothing. They brought that on themselves." he shrugs noncommittally before grabbing some scones and standing, "I think I'm done with breakfast, we've got an hour left til classes start, want to head to the library?"

...

She slowly nods, "I think I'm done too..." she mutters, sliding her plate away and following after him.

Harry throws one last glance over his shoulder at the Slytherins and momentarily locks eyes with Malfoy. He smiles and gives a slight nod before finally leaving.

"Say, Hermione, did you hear anything about those Parseltongue books?"

"Yes..." she quietly answers, still perturbed about what Harry had done. He might have had a reason for it, but using those worms was way too far in her opinion... Shaking her head, she continues. "They're apparently very expensive, only found in Indian auctions and almost all written in Hindi. Sorry if that doesn't help?"

"It's fine... Just another place I need to visit."

"Another? Where else have you been?" she curiously asked.

"The Arctic, North and South America, parts of Europe, Africa. You'd be surprised how easy it is for wizards and witches to travel."

She perks up, "Really?"

He nods, "Maybe in the future I could show you some places, there's a lot to learn out there that the school isn't allowed to teach..."

"Surely there's a reason for that though?"

"Whatever reason they have doesn't exonerate them from concealing and restricting knowledge.
