Mana: So sorry that I haven't updated, I've been busy with my Fictionpress account!

Sophie: And that's more important than us, why?

Ron: I feel so wanted...

Hermione: (sighs) Oh Ronald...

Harry: Mana doesn't own me, my friends or my sister!

Mana: Now here's this chapter!

"There, look."

"Where?"

"Next to the tall kid with the red hair."

"Wearing the glasses?"

"The girl with the auburn hair?"

"Did you see their faces?"

"Did you see their scar?"

Whispers followed Harry and Sophie from the moment they left their dormitories the next day. People lining up outside classrooms stood on tiptoe to get a look at them, or doubled back to pass them in the corridors again, staring.

The twins wished they wouldn't, because Harry was trying to concentrate on finding his way to classes, while Sophie was trying to read and walk at the same time, and it wasn't the easiest thing to do when people were in front of you all the time.

There were a hundred and forty-two staircases at Hogwarts: wide, sweeping ones; narrow, rickety ones; some that led somewhere different on a Friday; some with a vanishing step halfway up that you had to remember to jump. Then there were doors that wouldn't open unless you asked politely, or tickled them in exactly the right place, and doors that weren't really doors at all, but solid walls just pretending. It was also very hard to remember where anything was, because it all seemed to move around a lot.

The people in the portraits kept going to visit each other, and Harry was sure the coats of armour could walk.

The ghosts didn't help, either. It was always a nasty shock when one of them glided suddenly through a door you were trying to open. Nearly Headless Nick was always happy to point new Gryffindors in the right direction, but Peeves the Poltergeist was worth two locked doors and a trick staircase if you met him when you were late for class. He would drop wastepaper baskets on your head, pull rugs from under your feet, pelt you with bits of chalk, or sneak up behind you, invisible, grab your nose, and screech, "GOT YOUR CONK!"

Even worse than Peeves, if that was possible, was the caretaker, Argus Filch. Harry and Ron managed to get on the wrong side of him on their very first morning. Filch found them trying to force their way through a door that unluckily turned out to be the entrance to the out-of-bounds corridor on the third floor.

He wouldn't believe they were lost, was sure they were trying to break into it on purpose, and was threatening to lock them in the dungeons when they were rescued by Professor Quirrell, who was passing. Sophie was with Hermione, so she didn't know until Harry told her, to which she and Hermione smirked.

Filch owned a cat called Mrs. Norris, a scrawny, dust-coloured creature with bulging, lamp like eyes just like Filch's. She patrolled the corridors alone. Break a rule in front of her, put just one toe out of line, and she'd whisk off for Filch, who'd appear, wheezing, two seconds later.

Filch knew the secret passageways of the school better than anyone (except perhaps the Weasley twins) and could pop up as suddenly as any of the ghosts. The students all hated him, and it was the dearest ambition of many to give Mrs. Norris a good kick.

And then, once you had managed to find them, there were the classes themselves. There was a lot more to magic, as the twins quickly found out, than waving your wand and saying a few funny words.

They had to study the night skies through their telescopes every Wednesday at midnight and learn the names of different stars and the movements of the planets.

Three times a week they went out to the greenhouses behind the castle to study Herbology, with a dumpy little witch called Professor Sprout, where they learned how to take care of all the strange plants and fungi, and found out what they were used for.

Easily the most boring class was History of Magic, which was the only one taught by a ghost. Professor Binns had been very old indeed when he had fallen asleep in front of the staff room fire and got up next morning to teach, leaving his body behind him. Binns droned on and on while they scribbled down names and dates, and got Emetic the Evil and Uric the Oddball mixed up.

Professor Flitwick, the Charms teacher, was a tiny little wizard who had to stand on a pile of books to see over his desk. At the start of their first class he took the roll call, and when he reached Harry's name he gave an excited squeak and toppled out of sight. When he got to Sophie's, he fainted.

Professor McGonagall was again different. Harry had been quite right to think she wasn't a teacher to cross, while Sophie smirked at him. Strict and clever, she gave them a talking-to the moment they sat down in her first class.

"Transfiguration is some of the most complex and dangerous magic you will learn at Hogwarts," she said. "Anyone messing around in my class will leave and not come back. You have been warned."

Then she changed her desk into a pig and back again. They were all very impressed and couldn't wait to get started, but soon realized they weren't going to be changing the furniture into animals for a long time.

After taking a lot of complicated notes, they were each given a match and started trying to turn it into a needle. By the end of the lesson, only Hermione and Sophie had made any difference to their matches; Professor McGonagall showed the class how they had gone all silver and pointy and gave the girls a rare smile.

The class everyone had really been looking forward to was Defence Against the Dark Arts, but Quirrell's lessons turned out to be a bit of a joke. His classroom smelled strongly of garlic, which everyone said was to ward off a vampire he'd met in Romania and was afraid would be coming back to get him one of these days. His turban, he told them, had been given to him by an African prince as a thank-you for getting rid of a troublesome zombie, but they weren't sure they believed this story. For one thing, when Seamus Finnigan asked eagerly to hear how Quirrell had fought off the zombie, Quirrell went pink and started talking about the weather; for another, they had noticed that a funny smell hung around the turban, and the Weasley twins insisted that it was stuffed full of garlic as well, so that Quirrell was protected wherever he went.

Harry and Sophie were very relieved to find out that they weren't miles behind everyone else. Lots of people had come from Muggle families and, like them, hadn't had any idea that they were witches and wizards. There was so much to learn that even people like Ron didn't have much of a head start.

Friday was an important day for Harry and Ron. They finally managed to find their way down to the Great Hall for breakfast without getting lost once. Sophie grinned and patted them on the back, mockingly congratulating them.

"What have we got today?" Harry asked as he poured sugar on his porridge.

"Double Potions with the Slytherins," said Sophie at once.

"Snape's Head of Slytherin House. They say he always favours them — we'll be able to see if it's true," Ron added.

"Wish McGonagall favoured us," said Harry.

Professor McGonagall was head of Gryffindor House, but it hadn't stopped her from giving them a huge pile of homework the day before, which Sophie had already finished with Hermione..

Just then, the mail arrived. Harry and Sophie had gotten used to this by now, but it had given them a bit of a shock on the first morning, when about a hundred owls had suddenly streamed into the Great Hall during breakfast, circling the tables until they saw their owners, and dropping letters and packages onto their laps.

Hedwig hadn't brought Harry anything so far. She sometimes flew in to nibble his ear and have a bit of toast before going off to sleep in the Owlery with the other school owls or going to the Gryffindor girl's dormitory to play with Charm.

This morning, however, she fluttered down between the marmalade and the sugar bowl and dropped a note onto Harry's plate.

Harry tore it open at once. It said, in a very untidy scrawl:

Dear Harry,

I know you get Friday afternoons off, so would you like to come and have a cup of tea with me around three with your sister?

I want to hear all about your first week. Send us an answer back with Hedwig.

Hagrid

Harry borrowed Ron's quill, scribbled Yes, please, see you lateron the back of the note, and sent Hedwig off again.

It was lucky that Harry had tea with Hagrid to look forward to, because the Potions lesson turned out to be the worst thing that had happened to him so far. The opposite had happened with Sophie.

At the start-of-term banquet, Harry had gotten the idea that Professor Snape disliked him. By the end of the first Potions lesson, he knew he'd been wrong. Snape didn't dislike Harry — he hatedhim. What he couldn't understand, however, was why Snape seemed to like Sophie so much. His sister was stumped too. Why would one of her favourite teachers be so horrible to her brother?

Potions lessons took place down in one of the dungeons. It was colder here than up in the main castle, and would have been quite creepy enough without the pickled animals floating in glass jars all around the walls.

Snape, like Flitwick, started the class by taking the roll call, and like Flitwick, he paused at Harry's name.

"Ah, Yes," he said softly, "Harry Potter. Our new—celebrity."

Draco Malfoy and his friends Crabbe and Goyle sniggered behind their hands. Snape finished calling the names and looked up at the class. His eyes were black like Hagrid's, but they had none of Hagrid's warmth. They were cold and empty and made you think of dark tunnels.

He paused at Sophie's name and looked at her. Again, Sophie caught a flash of recognition in his eyes but this time she saw pain as well.

"You are here to learn the subtle science and exact art of potion making," he began. He spoke in barely more than a whisper, but they caught every word — like Professor McGonagall, Snape had the gift of keeping a class silent without effort.

"As there is little foolish wand-waving here, many of you will hardly believe this is magic. I don't expect you will really understand the beauty of the softly simmering cauldron with its shimmering fumes, the delicate power of liquids that creep through human veins, bewitching the mind, ensnaring the senses… I can teach you how to bottle fame, brew glory, even stopper death—if you aren't as big a bunch of dunderheads as I usually have to teach."

More silence followed this little speech. Harry and Ron exchanged looks with raised eyebrows. Hermione was on the edge of her seat and looked desperate to start proving that she wasn't a dunderhead, while Sophie had crossed her arms angrily.

"Potter!" said Snape suddenly. "What would I get if I added powdered root of asphodel to an infusion of wormwood?"

Powdered root of what to an infusion of what? Harry glanced at Ron, who looked as stumped as he was; Hermione and Sophie's hands had shot into the air.

"I don't know, sir," said Harry.

Snape's lips curled into a sneer.

"Tut, tut — fame clearly isn't everything."

He ignored Hermione's hand and turned to Sophie.

"Do you know. Miss Potter?"

"The Draught of Living Death," Sophie answered confidently, having picked up some extra books and come across the recipe.

"One point to Gryffindor." Sophie raised an eyebrow, while the Slytherins opened their mouths in surprise. "Let's try again. Potter, where would you look if I told you to find me a bezoar?"

Hermione stretched her hand as high into the air as it would go without her leaving her seat and Sophie raised her hand again, but Harry didn't have the faintest idea what a bezoar was. He tried not to look at Malfoy, Crabbe, and Goyle, who were shaking with laughter.

"I don't know, sir."

"Thought you wouldn't open a book before coming, eh, Potter?"

Harry forced himself to keep looking straight into those cold eyes. He had looked through his books at the Dursleys', but did Snape expect him to remember everything in One Thousand Magical Herbs and Fungi?

Snape was still ignoring Hermione's quivering hand and looked at Harry's sister again.

"The stomach of a goat, sir," Sophie said.

"What is the difference, Potter, between monkshood and wolfsbane?"

At this, Hermione stood up, her hand stretching toward the dungeon ceiling. Sophie pulled her down into her seat.

"I don't know," Harry said. "But my sister does, why don't you ask her again?"

People laughed and Snape said "If your sister can answer me correctly, I don't see why you can't. Miss Potter?" He turned to Sophie.

"They're the same plant, which go by the name of aconite," Sophie said and Snape looked impressed.

"Five points to Gryffindor," Snape said. "Why aren't you all copying that down?"

There was a sudden rummaging for quills and parchment. Over the noise, Snape said, "And a point will be taken from Gryffindor House for your cheek, Potter."

Things didn't improve for the Gryffindors as the Potions lesson continued. Snape put them all into pairs and set them to mixing up a simple potion to cure boils. He swept around in his long black cloak, watching them weigh dried nettles and crush snake fangs, criticizing almost everyone except Malfoy and Sophie, who he seemed to like.

He was just telling everyone to look at the perfect way Malfoy had stewed his horned slugs and the flawless light green of Sophie's potion when clouds of acid green smoke and a loud hissing filled the dungeon. Neville had somehow managed to melt Seamus's cauldron into a twisted blob, and their potion was seeping across the stone floor, burning holes in people's shoes. Within seconds, the whole class was standing on their stools while Neville, who had been drenched in the potion when the cauldron collapsed, moaned in pain as angry red boils sprang up all over his arms and legs.

"Idiot boy!" snarled Snape, clearing the spilled potion away with one wave of his wand. "I suppose you added the porcupine quills before taking the cauldron off the fire?"

Neville whimpered as boils started to pop up all over his nose.

"Take him up to the hospital wing," Snape spat at Seamus. Then he rounded on Harry and Ron, who had been working next to Neville.

"You — Potter — why didn't you tell him not to add the quills?

Thought he'd make you look good if he got it wrong, did you? That's another point you've lost for Gryffindor."

This was so unfair that Harry opened his mouth to argue, but Ron kicked him behind their cauldron.

"Don't push it," he muttered, "I've heard Snape can turn very nasty."

"But Professor, Harry was concentrating on his own potion!" Sophie said to Snape, who looked at her. For a moment, Harry was afraid that Sophie would be given detention but Snape simply said "Very well, I'll let it slide this time." Sophie looked at Harry with relief, while Ron's mouth was open.

As they climbed the steps out of the dungeon an hour later, Harry's mind was racing and his spirits were low. He'd lost a point for Gryffindor in his very first week—whydid Snape hate him so much?

"Cheer up," said Ron, "Snape's always taking points off Fred and George. Although I don't know how you did that with him, Sophie. He must really like you. Can I come and meet Hagrid with you two?"

At five to three they left the castle (Sophie asking Hermione to organise her notes for her) and made their way across the grounds. Hagrid lived in a small wooden house on the edge of the forbidden forest. A crossbow and a pair of galoshes were outside the front door.

When Harry knocked they heard a frantic scrabbling from inside and several booming barks. Then Hagrid's voice rang out, saying, "Back, Fang —back."

Hagrid's big, hairy face appeared in the crack as he pulled the door open.

"Hang on," he said. "Back, Fang."

He let them in, struggling to keep a hold on the collar of an enormous black boarhound.

There was only one room inside. Hams and pheasants were hanging from the ceiling, a copper kettle was boiling on the open fire, and in the corner stood a massive bed with a patchwork quilt over it.

"Make yerselves at home," said Hagrid, letting go of Fang, who bounded straight at Ron and started licking his ears. Like Hagrid, Fang was clearly not as fierce as he looked.

"This is Ron," Harry told Hagrid, who was pouring boiling water into a large teapot and putting rock cakes onto a plate.

"Another Weasley, eh?" said Hagrid, glancing at Ron's freckles.

Way to make him feel betterSophie thought. He doesn't want to be compared to his siblings; he wants to be his own person!

"I spent half me life chasin' yer twin brothers away from the forest."

The rock cakes were shapeless lumps with raisins that almost broke their teeth, but Harry, Sophie and Ron pretended to be enjoying them as they told Hagrid all about their first lessons.

Fang rested his head on Harry's knee and drooled all over his robes, while Sophie took a real liking to him and patted him. Charm meowed cautiously from within her robes and Fang looked at them, interested.

They were delighted to hear Hagrid call Filch "that old git."

"An' as fer that cat, Mrs. Norris, I'd like ter introduce her to Fang sometime. D'yeh know, every time I go up ter the school, she follows me everywhere? Can't get rid of her — Filch puts her up to it."

Harry told Hagrid about Snape's lesson. Hagrid, like Ron, told Harry not to worry about it, that Snape liked hardly any of the students.

"But he seemed to really hateme. And he liked my sister enough to not take a point off! How does that work?"

"Rubbish!" said Hagrid. "Why should he hate yeh?"

Yet Harry couldn't help thinking that Hagrid didn't quite meet his eyes when he said that.

"How's yer brother Charlie?" Hagrid asked Ron. "I liked him a lot — great with animals."

Harry wondered if Hagrid had changed the subject on purpose, while Sophie knew that he had. While Ron told Hagrid all about Charlie's work with dragons, Harry picked up a piece of paper that was lying on the table under the tea cozy. It was a cutting from the Daily Prophet:

GRINGOTTS BREAK-IN LATEST

Investigations continue into the break-in at Gringotts on 31 July, widely believed to be the work of Dark wizards or witches unknown. Gringotts goblins today insisted that nothing had been taken. The vault that was searched had in fact been emptied the same day.

"But we're not telling you what was in there, so keep your noses out if you know what's good for you," said a Gringotts spokesgoblin this afternoon.

Harry remembered Ron telling him on the train that someone had tried to rob Gringotts, but Ron hadn't mentioned the date.

"Hagrid!" said Harry, "that Gringotts break in happened on our birthday! It might've been happening while we were there!"

"What?" Sophie hissed, looking at the paper.

There was no doubt about it; Hagrid definitely didn't meet Harry's eyes this time. He grunted and offered him another rock cake. Sophie read the story for herself. The vault that was searched had in fact been emptied earlier that same day.Hagrid had emptied vault seven hundred and thirteen, if you could call it emptying, taking out that grubby little package. Had that been what the thieves were looking for? Sophie was starting to piece things together...

As Harry, Sophie and Ron walked back to the castle for dinner, their pockets weighed down with rock cakes they'd been too polite to refuse, Harry thought that none of the lessons he'd had so far had given him as much to think about as tea with Hagrid. Had Hagrid collected that package just in time? Where was it now? And did Hagrid know something about Snape that he didn't want to tell Harry?

YepSophie said in his mind and he grunted.

"Sophie, stop it!" he said and she grinned cheekily.

"What is she doing?" Ron asked, puzzled.

"Oh, we have a telepathic connection," Sophie explained.

"Which she uses to annoy me!" Harry said, pointing to his sister. Ron stared at the both of them.

"Bloody hell," he finally said.
