**NOTE**

Tom Riddle was a fifth year Slytherin prefect. He had struggled slightly to make it to such a position of power among the school of Hogwarts.

Because he was a halfblood - which was only discovered recently - he'd been treated terribly by his own House, because they thought he was a muggleborn. And then his ability to speak with snakes came into the light and things changed.

He went to Gringotts and took the Heritage Potion, revealing that he was the last of Slytherin's noble line. And he returned to his fifth year with a significantly better wardrobe and and completely rehauling of himself.

Tom's long, drawn out revenge against the people of his House who did him wrong over the years, began.

They knew it was him.

They knew they were suffering for past actions.

There was nothing they could do, because Slytherins didn't air their grievances with each other to the other Houses.

Tom didn't care what happened, because there was much time to make up for.

He was finally reaching the point in his life where things mattered and affected his future.

This was his O.W.L. year. This was the year he had to get the best marks, in order to get into good N.E.W.T. classes. This year could make or break his future.

His only opposition as far as grading, was a muggleborn by the name of Hermione Granger. She dominated nearly every class there was. All except Defense, which her friend Harry Potter was the top of, beating both Tom and Hermione.

Yes, Potter and Granger were both of a small group of people. All considered outcasts by their own Houses.

Potter was a Gryffindor, but was different. He refused to shun Slytherins and that made him less interesting in the eyes of the lions. The Weasley twins were also Gryffindors, but were disliked for their pranks and frank way of speaking. Granger and Lovegood were Ravenclaws and were bullied for being too smart and too weird, in that order. Longbottom was a Hufflepuff who was too shy to speak to anyone outside his group. His rampant fear of Severus Snape was also what made him a target for bullies.

This group frequently skipped meals, opting to eat in the Kitchens. Tom had found that out earlier on in the year.

There was mo rule against it. Anyone could do it. Most people didn't know where the Kitchens were though, so it didn't matter to them. But Potter was friends with the House Elves of Hogwarts and they aided him in nearly everything.

The pure opportunities that group alone had, were amazing.

The pranksters of the school for defense, the brains of the school for studying, he would swear up and down that Lovegood was a Seer, Longbottom was a budding Herbologist with in depth knowledge of plants, and Potter was the leader than kept them together, whether he noticed it or not.

An odd group, but no less amazing.

Tom had never spoken to any of them though. He'd never felt the need to.

He didn't know much about them, but he knew more than most of the school did.

He was observant after all.

But even with that, Tom wasn't ready for this.

He'd been patrolling, when he noticed Harry Potter slipping into the Room of Requirement. Potter was out after curfew and Tom was curious, so he followed swiftly, slipping into the room before the door closed completely.

A disillusionment charm allowed him to watch safely as Potter stood in a circle and several practice dummies rose from the floor.

Tom was left breathless in the new moment as Potter spun on the spot, casting spells non-verbally.

Tom knew the teen was good at Defense, but these were some advanced Transfiguration spells used on those dummies and he knew - like the rest of the school - that Harry Potter was not good in anything but Defense. So how could he manage such complicated spell-work?

Potter twirled gracefully, a great difference from his awkward walk. He usually looked small and fidgety, but this Potter. This one knew what he was doing and what he was capable of. This one was skill personified. This one reminded Tom of himself. This Harry Potter was one to watch out for.

And he took Tom's breath away.

He didn't look like a ruffian in this moment. He looked like the pureblood raised young man he was supposed to be.

And as soon as it all started, Potter shifted into a perfectly 'at ease' stance. The dummies had been reduced to animals, tables, and all manner of clothing. He was smiling to himself, obviously impressed with his work. His work which had been done in under ten seconds, against over twenty enemies.

Tom couldn't help himself. He had to know. He had to understand, because this Harry Potter went against all preconceived notions of Hogwarts.

He dropped his illusion and spoke.

"Why do you perform so well here, but in class you're mediocre?"

Potter gave a yelp and spun with a speed that Tom hadn't expected, throwing a curse that Tom didn't know, because it too was done non-verbally.

He barely managed to summon his shield in time.

A great amount of power was in that curse, since it was capable of making Tom's shield waiver for a few seconds.

"Riddle?"

Potter sighed and ran a hand through his black, messy locks.

"The bloody hell are you doing here?"

Tom allowed his shield to dissipate and he gave the Gryffindor a look after gesturing to his Prefect badge. "You're out after curfew."

Potter flushed instantly, "Oh."

"Yes, 'oh'," Tom repeated blandly "If you tell me why you deliberately withhold your ability in class, no one will ever know of your transgressions, since I'm certain this is a repetitive process."

Potter sent him a mild glare. "Even if it was, I wouldn't admit to anything."

Tom couldn't help but smirk. A very Slytherin response. How… intriguing.

"Why do you care, Riddle?"

"I'm curious."

Potter huffed and a plush chair appeared. Potter sank into it and sighed.

"Revenge," he answered simply.

Tom sent his desires to the room, delighting in the chair that appeared not too far from Potter's own. Tom made his way over and sat.

"And since when do Gryffindors downplay their power or presence? Especially for revenge?"

Potter shrugged, "I was supposed to be a Slytherin."

Tom's jaw dropped minutely, but it was enough for Potter to see and to smirk.

"Everyone of my friends knows already, so it isn't a big deal. But I couldn't afford to be in Slytherin."

That answer did not please Tom. "I was under the impression that you didn't hate Slytherin."

"I don't!" Potter sneered. "Despite what some people think, Light families aren't as nice as they claim to be. So while there are Dark families like the Lestranges and Blacks who would disown their children for being sorted to anywhere but Slytherin, Light families that disown children for being Slytherin, do exist. My family is one of them."

The revelation made Tom's head spin. The Potter family would actually disown their children for being Slytherin?

His disbelief must have been visible because Potter rose to explain.

"My dad is a big bully. He hates Slytherins. He's the reason Professor Snape is so terrible to Gryffindors. He and my godfather tormented Snape for being a Slytherin. Their pure hatred for anything Slytherin is just… too much. And because my mom's friendship with Snape died, she allows them to speak terribly about Slytherins and pretty much do what they want."

Potter looked down for a second. "You may not know, but I have an older sister in Gryffindor. Her name is Rosalie and she goes by Potter-Black. Since she's referred to as Black by most people, some assumed she's Sirius' daughter and don't know that she and I are related. She's a seventh year."

Tom had heard of her, but he didn't know that she was a Potter. So the teen's words were true so far.

"Rosalie isn't my only sibling. I'm the youngest. Our parents had a son named John. He was ten years older than Rosalie. She barely remembers him and only has one photograph of him. He came to Hogwarts and was sorted into Slytherin."

Potter frowned and looked away.

"I heard from Sirius one night when he was drunk, that John was removed from Hogwarts the next day, stripped of his name and place in the Potter family, his magic was bound permanently, and he was… dumped at some muggle orphanage. The Potter family couldn't afford to have 'evil' taint their line."

Tom was dumbstruck. The Potters. The supposedly best family on the Light side, did that to their son all because he was sorted into Slytherin? Judging by the look on Harry's face, it wasn't a lie.

"I was ten when I learned that from my godfather. I hadn't considered it much until the Hat was on my head and started talking about how I'd do well in Slytherin. I was so scared. I begged that stupid Hat and I demanded that it look at the memory of when I learned about John. The Hat - Tavin, his name is - took pity on me and ranted about my foolish parents for a few moments, before placing me in Gryffindor.

You will never understand the horror. I could have ended up like John."

The teen looked shaken. The memory must have been hard to think of. Tom was still caught up on the fact that the Potters would go so far.

"How is hiding your skill getting revenge though?" Tom asked, finally getting to the matter of the situation.

Harry scoffed, "'Rosalie is good at everything'. At least, my parents are too stupid to see how pathetic she is. She barely gets A's in her classes and it isn't because she tries. Lily wanted a daughter for so long and of course a daughter requires more protection than a son does, so James and Lily pay her more attention. They seem to think she's the messiah reborn."

Tom finally understood. The Potters cherished their daughter and ignored their youngest child.

"And what is your strategy?"

Harry smiled darkly, "The only important grades we receive are O.W.L.s and N.E.W.T.s, so all I have to do is excel in those. James and Lily haven't actually spoken to me in years and don't know anything about how I do in school. It's like I don't exist to them. I plan to join my friends in building a multi-faceted business corporation."

Tom's interest was peaked. "And what is this business of yours going to sell?"

Harry smiled, more happily this time. "I've already begun designing brooms and creating them. I'm also going for Warding and Spell Creation. Hermione will be a Potions Mistress and will be handling the Potioneering section. Neville will be a Herbologist no doubt and will assist Mione in growing and caring for the ingredients. The twins started creating their section many years ago. They'll be the prank section and will outstrip Zonko's easily. Luna is a Seer and will head over all things pertaining to the Sight and Divination.

All of these smaller companies will be a part of one large corporation. With Mione's help, I've been able to make the proper investments with savings given from everyone and in doing so, I have created a separate vault for our plans. The twins will begin their part of the agreement as soon as they graduate.

We're calling it Whatchamacallitz."

Tom's mouth dropped, "Really?"

"Yes."

He couldn't help it. "Really?!"

"It's fun to say!" Harry grinned. "It will be comprised of Weasleys' Wizard Wheezes, Wonderful Wonder World, and Wacky Wizarding Wirbling Wonderments."

Tom simply stared at the Gryffindor. "You're really going to name it… all those names?"

He was nearly blinded by the smile Harry sent his way.

There would be no changing his mind apparently.

"It was a group decision you know."

No need to be so bloody happy about it.

Tom stood and brushed his robes off. "I won't tell anyone about your late night traipsing."

Just as those otherworldly, green eyes widened, he added, "But I would like to join you every other night."

Harry was silent for a moment, before nodding. "Okay. So long as you say nothing, I don't care. I usually come here every night at ten and leave at eleven. Sometimes one of my friends comes with me. I'll let them know."

Tom nodded quietly, before smirking, "Well then, Harry, I look forward to it."

Tom turned and strode from the room. This would be interesting. Very interesting.

A/N: First is done.

How was it? Let me know.
