Chapter 1 – Slytherin's sudden change in attitude

--

The wind blew furiously, causing the dead leaves to scatter along its path as the sky above turned cloudy. The road outside King Cross Station was busy as usual. It was packed with adult muggles on their way to work in cars and buses in the early hours of the weekday morning. As always, the main road was full of different vehicles caught in a traffic jam with some that had probably broken down and impatient muggles arguing with each other for blocking the way. No one paid attention to an oddly dressed woman as she crossed the main road, passing several cars along the way towards King Cross Station. She was merely one of the crowd and but this was no ordinary muggle. Charlotte Marvolo Riddle -the granddaughter of Lord Voldemort smiled to herself as she stepped into the station. No one knew the Dark Lord had a granddaughter –no muggle knew about her existence.

For the past sixteen years of solitary existence, Charlotte had been keeping very much to herself as she studied curses, hexes and charms and at times, Voldemort would teach her what he knew about them if he had time for her. Charlotte was the offspring of a pureblood wizard and a Muggleborn, just like her grandfather who was also a Halfblood. Her father, Thomas Marvolo Riddle was Voldemort's only son and a Death Eater and as for her mother, she was a muggle who abandoned her after she found out who Charlotte was. Her parents died when she was two years old and she had been raised in a orphanage till when she turned ten that she discovered she was a witch. Knowing that Wizards and Witches around the world had feared to mention her grandfather's name for years, Charlotte had secretly changed her surname to 'Malfoy' whenever she needed to introduce herself. It was difficult trying to hide her true identity for more than sixteen years. Only one person knew her true name …. her one and only best friend, Genevieve Wenda Lachlan, a seventh year Slytherin like her except that she's a Pureblood.

Genevieve and Charlotte had grown up together and they always had good fun with their wands, picking up younger muggles by their ankles, suspending them in midair and throwing them about thirty feet into the distance. They would hide in the shadows waiting for unsuspecting victims, transforming and giving themselves the head of a zombie and showing their mutated faces to any muggle who happened to pass their hiding place. Those they preyed upon would be frightened out of their wits, running off and screaming at the top of their voices about monsters. Some had been targeted again and again until they fainted from fright. Whenever that happened, Genevieve and Charlotte had to make a run from the Ministry of Magic, hoping they wouldn't be caught and they had been lucky so far.

Charlotte stood at a distance, watching in amusement at those muggle arguments. She had a youthful, pure and beautiful oval shaped face, dark brown over-the-shoulder length straight hair with light brown highlights, pale skin, five loop earrings on each ear and deep set piercing eyes behind frameless spectacles. But there was a strange thing about her eyes. Her pupils were blood red with a cold and creepy hunger in them. Charlotte looked odd with a pair of faded jeans that had seen better days, a black tie hung loosely around her neck, a white formal blouse with the sleeves rolled up above her elbows, a pair of black ankle length converse shoes with black and white laces which were worn loosely and she had used black eye liner that gave her a punk rock look. She appeared to be no older than seventeen and besides; she was kind of cool actually. She had her mother's looks but with eyes like her grandfather, Lord Voldemort. Charlotte had seen enough of those arguing muggles. From somewhere a clock struck ten and she turned on her heels and went into the station, pushing her trunk on a trolley ahead of her.

Stupid muggles... they're always so particular about little things like these –when will they ever learn?

Many muggles passed her without so much as a glance; it was as if she was invisible. No one even noticed that she was not one of them as Charlotte pushed her way through towards platforms Nine and Ten. She knocked into a ten year old muggle boy but did not apologize as he burst into tears when she threw him a dark look which frightened him. She turned away, muttering about silly idiots as she approached platforms Nine and Ten and looked up at the huge clock above her.

"Twenty minutes to eleven..." Charlotte murmured to herself before a smile lit up her face. "Hey Gene'!"

"Hey Charlotte" Genevieve smiled back, pushing her own trolley and trunk as she walked towards her best friend. "How's your summer?"

Charlotte merely shrugged. "I've learnt more new hexes than last summer and even got some of them on myself. Grand dad wasn't too pleased though cos' I nearly bled to death. What about you?"

"Oh, the usual. Always boring - what sort of hexes were they? Surely, you're not in your right mind to be so pleased about nearly getting yourself killed – not when your grandfather loves you so. How's the Dark Lord doing?" Genevieve grinned.

"I have no idea what they were. I was cleaning out the attic during summer when I saw this really old book – I supposed it's one of Salazar Slytherin's books on old hexes that only a few knew about. Granddad's building up his power as usual. Anyway, let's get a move on or those stupid newbies will take up all the good seats on the Hogwarts Express." Charlotte chuckled as she pushed her trolley towards the wall between Platforms Nine and Ten. "Ready?"

Genevieve gave the thumbs up as she giggled. "Ready when you are and do show me that book later. Let's get in together on the count of three – three!"

Charlotte had to ensure that her black Norwegian Forest cat was safely on top of her trunk. It was none other than Nagini, Voldemort's loyal snake in true form but which had been transfigured into a cat and adopted by her. Genevieve smiled broadly, her eyes deep in concentration and with a great push on their trolleys, both girls broke into a run and picking up speed before disappearing through the wall between the platforms.

--

Sounds of student chattering, cats of different breeds mewing, rats squeaking at each other, owls hooting their greetings and toads of all sizes croaking loudly created quite a din. Genevieve and Charlotte emerged out of the walls and stood facing the scarlet steam engine train. It was as magnificent as ever letting out puffs of smoke from its engines as the two girls began pushing their way through a crowd of students and their parents. Charlotte's trolley suddenly got entangled with one that belonged to another student and she roughly tried to jerk it free. Genevieve on the other hand had to rub her knee where someone's trolley had painfully knocked into her. Nagini, its fur standing on end, hissed at the students surrounding them as Charlotte swore angrily at a boy who blocked her way.

"Shove off, kid!" she hissed, glaring at the boy who seemed the same year as her, with freckles on his face, flaming red hair and large feet. He was standing among a group of boys, a girl and 2 adults which she guessed to be his family. One of the boys stood out from the group with his messy jet black hair, green eyes and a lightning bolt shaped scar across his forehead and Charlotte knew instantly who he was as she narrowed her eyes for a minute before pulling Genviene away.

"What's up with her?" The boy she had glared at earlier looked at her with raised brows and gasped when he caught sight of her eyes. They looked oddly familiar to him but she had already turned away. "Bloody hell! Harry, don't tell me that she's …"

The boy he was talking to was none other than Harry Potter, The-Boy-Who-Lived. He merely stared at his best friend, Ronald Weasley. "Her eyes looked exactly like... Voldemort's?"

They were now staring transfixed at the girls' backs before they got swallowed up by the crowd. Charlotte released her grip on Genevieve once they were out of earshot. "Know who that brat is, Gene'?"

Genevieve nodded mutely as she gazed up at Charlotte. "Yeah but who cares about Potter anyway? No point in distracting ourselves with thoughts of him at Hogwarts."

"Yeah... I guess you can say that for now –Impedimenta" Charlotte agreed, pointing her wand at a first year student and watching him being knocked backwards off his feet.

"Nice one, Charlotte."

"Thanks, Gene'. Now, let's get a move on to one of the cabins before the best seats are all taken. Come on, Nagini." Charlotte slipped her wand back into her jeans pocket before the sound of the whistle was heard blasting from the train, signaling the start of the journey. "Let's go."

Both girls ran towards the train, pushing their trolleys through the area that was now crowded with parents waving goodbye to their children. They stopped abruptly and whisked their trunks in with a bit of help from their wands before flinging themselves in through the cabin door. Nagini shot in after them and rubbed its neck against Charlotte's leg, purring. The train began to move and they were off, out of the station and moving in the direction of Hogwarts.

--

"Want to sit at the last cabin this time?" Genevieve asked, pulling her trunk behind her as Charlotte struggled with hers.

"Yeah... I... suppose... so..." Charlotte panted.

Both of them pulled their trunks along the passageways, past many cabins and had almost reached the last one when the door to one of the cabins slid open. Out appeared two students, Hermione Granger with her profusion of brown wavy hair and Ronald Weasley, the freckled faced boy whom Charlotte and Genevieve had met earlier. They stared at each other in silence.

"Are you 2 going to move or do we have to blast you out of the way?" Charlotte taunted coldly, narrowing her eyes as she folded her arms.

"Not unless you want to wreck the train before reaching Hogwarts and get detention?" said Hermione coolly, pointing to her Prefect badge.

"Ickie prefect, aren't you?" Genevieve sniggered mischievously as she locked eyes with her.

"Not ickie enough from what I see." Charlotte chuckled. "Gene, I guessed it's a bad choice to choose this cabin, especially if it's filled with ickie kids."

Ron stared at Charlotte, unable to take his eyes off her as he bit his lower lip. He expected her to turn into Voldemort at any moment and it made him shiver slightly. With colour draining from his face, he seemed as pale as a corpse. Both Genevieve and Charlotte noticed his parlor and sniggered as Hermione rolled her eyes and shook him by his shoulders roughly.

"Honestly, Ronald! Get a grip on yourself!"

Charlotte managed to stop herself from laughing out loud as she asked Hermoine while grinning mischievously. "Is he always like this?"

Hermione, who seemed to have forgotten the two girl's rudeness, was feeling worried about Ron as he looked as if he was about to faint. "No, he's usually not like this and I don't have the faintest idea what's wrong with him right now."

"Perhaps he saw someone's undies?" Genevieve joked, giggling behind her hands as Charlotte chuckled. Hermione just furrowed her brow.

"No, of course not. He's been fine this morning till..."

"- at the railway station? Yes, he looks like he had seen something that might attack him. Like me for instance." Charlotte gloated and added quickly. "I noticed him staring at me ever since he first saw me at the station, as though I would start cursing his butt off the moment I see him."

"And did you?" Hermione looked at Charlotte; her hands still on Ron's shoulder as though afraid he might collapse the moment she let go of him.

Genevieve gave a laugh. "Charlotte cursing him off? Why bother wasting our hexes when we could use them for better things?"

"No, and Gene's right. Why would I want to do that?"

"No idea..." began Hermione when Ron cut in suddenly as though he had just got his voice back.

"-you're You-Know-Who, aren't you?"

Charlotte raised a brow and retorted "Voldemort? How can he, a man who's in hiding, disguise himself as a seventeen year old girl and talking to you both without killing anyone at all?"

Hermione and Ron gasped when Charlotte mentioned Voldemort's name. No one else would dare to mention his name aloud other than Harry, Lupin, Sirius, Dumbledore and some members of the Order of the Phoenix. Genevieve only smirked as she looked at Charlotte, nodding in agreement. Hermione mulled over her words before she looked back at the two Slytherin girls.

"Maybe you're right... I suppose Ron's thinking too much..."

Ron was taken aback by her answer and his jaw dropped in disbelief. Genevieve smiled contemptuously as Charlotte began searching through her jeans pockets before taking something out and handing it to him. Ron almost wanted to scream but stopped himself just in time when he noticed what it was …. a Chocolate Frog.

"You thought I was going to kill you again? Hah, as if! Anyway, take this as it will help to make you feel better."

Ron stared at the frog but did not take it. His jaw tightened as he stared at her. He felt as if he could see his reflection in those red blood eyes of hers and they had a look of hunger in them. Ron gulped uneasily as Hermione quickly took the frog, thanked her and flashed her eyes at him while shaking her head. As Charlotte and Genevieve laughed, Hermione suddenly remembered they were supposed to go to the front of the train for the prefect briefing and shrieked in alarm.

"Oh no! We've been here too long and have forgotten the time! We're supposed to be up at the front of the train for the Prefect briefing! We would've left earlier if it hadn't been for you, Ronald!"

Without another word, Hermione pulled Ron with her, past Charlotte and Genevieve and hurried down the passageways. The two looked at each other, chuckling slightly before taking the last cabin which was in front of them. As Charlotte slid open the door, they found themselves face to face with someone they knew only too well. It was Harry Potter and he was alone. They hesitated slightly before stepping in, pulling their trunks behind them. Nagini hissed, locking its eyes on Harry as it recognized him. Genevieve picked Nagini up in her arms and scratched the back of its ears. Charlotte looked away, her hatred swelling up in her chest as Harry looked in astonishment at them.

"Mind if we take this cabin, Potter?" Genevieve asked quietly, not looking at him either when Charlotte didn't say anything.

"Er …." Harry began as he looked at Charlotte and then at Genevieve before he continued "sure".

Both of them took the opposite seat furthest from him as they placed their trunk up onto the luggage rack above them. As Harry wondered why they were avoiding his gaze, his stomach gave a funny jolt when he noticed the cat in Genevieve's arms staring at him intensely. Somehow, its eyes reminded him of those which belonged to Voldemort's snake Nagini. How could it possibly be the same as a cat and isn't it supposed to be with Voldemort now? Harry's mind was busy with these thoughts as the two girls sat down beside each other, still not looking at him. Charlotte slipped out her wand and an old tattered yellowish book from her trunk as Genevieve asked while rubbing her hands.

"Is this the book you've mentioned?"

Charlotte nodded and handed it to her. "Yeah"

"What does it do, Charlotte?" Genevieve looked interested as she took it from her and glanced through the pages briefly.

Harry sat up and looked at the book in interest. Perhaps it's a book full of an even much more advance Defence Against the Dark Arts? Charlotte merely ignored Harry as she continued to look at Genevieve. "Well, lots. Why don't you try them out yourself? I can help you if it gets out of hand."

"Hmmm... it looks complicated to me..."

"Go on, try one." Charlotte urged, indicating silently to Genevieve to use it on Harry.

Genevieve chanted, suddenly pointing at Harry "Pullus!"

Harry realized too late that the spell was aimed at him and couldn't dodge in time as he dropped off his seat, his eyes tightly closed. Charlotte chuckled and so did Genevieve as she went over towards him. Harry felt odd as he half opened his eyes. Everything around him had suddenly grown so big. As Harry tried to push himself up, he looked down and was horrified to discover that his hands had turned into a pair of wings with white feathers instead. He had become a rooster! Harry was stunned, his eyes widened in disbelief as he looked up at the two girls. Charlotte bent towards him and picked him up. Genevieve looked as though she was ready to use another hex on him as Nagini licked its lips. Harry felt outraged; clucking madly as he struggled to free himself but Charlotte was far too strong for him in his present form.

"Let's see what the great Harry Potter can do now that he's a Rooster. Perhaps Nagini would like a bite of him?" Charlotte laughed as she turned him upside down above the cat and shook him violently by his legs.

Feathers were falling off him as she shook him and he was getting dizzier by the minute. As he hung upside down, he caught a glimpse of the name on the trunk above them … Charlotte M. R.

And the name of her cat …. she had called it Nagini….

Nagini? Wasn't that the name of Voldemort's snake? Don't tell me that it's been transfigured into a cat and had become her pet? Who is she? Charlotte M. R.? M.R.? Bloody hell! M.R. as in, Marvolo Riddle? She's related to Voldemort? Tom Riddle? But how? That doesn't make any sense at all! Wasn't he supposed to be in hiding?

"Now, I'm sure Potter here needs to fatten up first before Nagini can enjoy its feast." Genevieve sniggered, pointing her wand at him again. Nagini mewed, its bloodshot eyes fixed on Harry's rooster form.

"Perhaps you're right. He seems too skinny but still, we need him to be alive as my granddad wants him, Gene'. I guess we'll just leave him as he is till I feel like undoing the transfiguration." Charlotte sniggered, squeezing Harry's thin legs so tightly that they were beginning to feel numb. Suddenly, there was a soft hiss which sounded to Harry like Parseltongue, and it was coming from Charlotte "Later, Nagini."

"Good idea, Charlotte."

Don't tell me that I'm going to be fed to it? This is so weird... definitely weird... At first it was Draco Malfoy who stunned me and hid me under my father's invisibility cloak, and now I'm a rooster. Blimey! She can speak Parseltongue! That means, she's related to Salazar Slytherin too! I wished Hermione and Ron would hurry up and find me...

Just then, the door of their cabin slid open and Ron and Hermione came in with some of the younger students and some from year six. Charlotte grinned mischievously when she saw Hermione and Ron while Genevieve smirked at the rest. Harry flapped furiously; his feathers were now littering the floor as he tried to get their attention. One of the youngest from the group, who looked no older than fifteen, faced Charlotte coldly. She reminded her of Ron as she too had flaming red hair and a freckled face.

"Aren't you a Slytherin? Shouldn't you be with that ferret Malfoy's group?" She asked, narrowing her gaze at Charlotte.

"Yeah, so? And what's with that attitude of yours?'' Charlotte challenged.

"Have you come to place a hex on us for taking this cabin?" Genevieve asked coolly.

Hermione butted in. "Ginny, they're alright and no, they aren't –they're not what you think they are as they aren't like Malfoy and the rest of the Slytherins."

Charlotte smirked even more. "Absolutely right! Now Gene', let's introduce ourselves to these ickie kids."

"Yup, the younger the kids, the cuter they get!" Genevieve chuckled. "I'm Genevieve Wenda Lachlan, Slytherin Seventh Year and this is Charlotte Malfoy, also a Seventh Year Slytherin."

Everyone grew quiet at this introduction but Charlotte and Genevieve merely sniggered as the group gaped at them. Harry was still trying to figure out how to get away but Nagini was keeping a close watch on him. He suddenly had an idea and pecked sharply at Charlotte's hand. It worked as she yelled in surprise and let go of him. Harry flapped off towards the door of the cabin and disappeared through the passageways.

"A rooster?" one of them exclaimed.

"Where did that come from?" asked another.

Charlotte ran after him angrily. "Stupid git! Urgh! I'll kill him!"

Once Charlotte had disappeared from view, Nagini scampered after her. Everyone had stepped out into the passageway and was wordlessly staring after them when Genevieve broke the silence. "Would anyone like a cup of tea?"

"Aren't you going to help her?" The girl with freckles like Ron spoke.

Genevieve shook her head, taking out chipped tea cups, a large tea pot and some tea bags from her trunk. "He knows his only hope lies with Charlotte so it's no use running away from her."

"Er, right..." Hermione broke in, not knowing what Genevieve meant by that as the latter began making tea for everyone. This particular scene reminded everyone of one of the Professors.

Everyone was silent as Genevieve tapped her wand on the tea pot. Suddenly, a stream of tea poured itself from the spout into the tea cups. She passed each of them a cup before she spoke. "Mind introducing yourselves?"

Everyone accepted the offer as Genevieve sat back down into her seat and noticed Charlotte's old tattered yellowish book lying opened on the seat. She quickly snapped it shut and put it away, before turning round to face the group. Hermione took a sip of her tea and smiled "I'm Hermione Granger, Gryffindor Seventh year and a Prefect but you would already know that."

"I'm Ronald Weasley, Gryffindor Seventh Year and a Prefect just like Hermione here. I'm also a Keeper in the Gryffindor Quidditch Team." Ron joined in as he blew his tea slightly before taking a sip too.

One of the boys, whom Genevieve hadn't seen before looked very nervous as though he was afraid of something but tried not to show it. "I'm N-Neville Longbottom, G-G-Gryffindor Seventh Year too"

"I'm Ginny Weasley, Ron's younger sister, Sixth year Gryffindor and I'm a chaser and sometimes a seeker in the Gryffndor Quidditch Team."

"The name's Luna Lovegood. I'm Ginny's classmate and same year as her but I'm in Ravenclaw."

Genevieve grinned mischievously as she sipped her tea. "Now we're all done with the introductions, thank you very much. So far I haven't seen any Hufflepuffs around."

Suddenly they all heard sounds of gagging and choking and everyone spun around to see where they were coming from. Hermione and Ron were hiccupping continuously when they suddenly began to vomit. Suddenly both of them appeared to be choking and gasping for air which caused Ginny and Neville to step back in shock. Genevieve chuckled as she popped a small red pill into their mouths. Hermione and Ron magically seemed to recover as both of them held onto the wall of the cabin. Ginny glared at Genevieve, waiting for a good explanation as Neville tried his best to help the two to a seat.

"Sorry about that - my mistake, an unintentional mistake. I must've used those tea bags with the Weasleys' Wizard Wheezes. Gred and Forge must've slipped those in again without Malfoy and me noticing."

Ginny looked astonished. "Fred and George? You mean my elder brothers? You know them?"

Genevieve simply nodded. "Of course I know them. We were good friends during our time at Hogwarts. They're always troublemakers just like us. Charlotte and I first met them on the first day of our first year. We were always giving them ideas for their own joke shop."

"Both of you were troublemakers just like them too?" Ron asked hoarsely after he had finally got his breath back.

Genevieve nodded again. "Yeah but sadly they left last year just when they were in their sixth years and Charlotte and I were left without them"

Hermione felt sorry for her as she suddenly thought about Harry. She quickly looked at them. "Hey guys, has anyone seen Harry at all? He was here when Ron and I left for the Prefect briefing."

Everyone shook their heads. Only Genevieve knew where he was and what he had become as she suddenly looked towards the door. "Ah! Charlotte's back!"
