AN- Sorry it took me so much time to update, I was busy with school and had no inspiration for a long time (math is like a dementor- it sucks all life out of you>>my invention!)
Anyway, reviews would be very much appreciated as always :)

Desclaimer: Yes, I do own Harry Potter, Ron ,Hermione and most important- Snape. I let Rowling use my story because I didn't wanna get rich.
Note- The author is a chronic liar.

On with the story!

Chapter Four: Invisible

For the first time in a long while, Harry woke up from a peaceful, dreamless sleep. Though it was still early in the morning, he was eager to start the new term. Looking at Ron, who was still asleep, Harry got up and went towards the window. The grounds were shining in the sun, though the Forbidden Forest looked as dark as always. Harry kept looking outside, enjoying his first morning at Hogwarts.

'What are you doing up there so early?' said a sleepy voice behind him. It was Ron, sitting on his bed, stretching.

'Nothing, just looking outside,' Harry replied and paused for a second, thinking. 'I missed Quidditch, you know, can't wait for the tryouts,' he added.

'Yeah,' said Ron, 'I wonder who will replace Fred and George now that they're out of school.'

'Ginny said she was going to try, remember?' asked Harry.

'Oh yeah,' replied Ron, 'I suppose she's OK, isn't she?' he asked.

'I think she's good. Could be a great beater,' Harry answered.

Hermione was already sitting in the Gryffindor table when they arrived at the Great Hall for breakfast. A group of forth year Ravenclaws passed by, whispering and pointing at them. Harry, who got used to this kind of behaviour around him, barely paid them any attention and sat next to Hermione, who was handing them the new time table.

'What took you two so long? Especially you, Ron. You were supposed to be here earlier to help me hand out the time table! You're lucky I asked Professor McGonagall for two more copies,' she said in one long breath.

Ron was looking at Hermione, surprised that she managed to say so much in such a little time, then looked at his time table with his eyes wide open. Harry, on the other hand, was already busy with his breakfast.

'Lucky?' exclaimed Ron, grabbing a piece of toast in his hand, 'Did you take a look at this? We have double Potions, double Transfiguration, History of Magic and it's all today!' he paused for a moment, glancing at the time table again.

'Double Potions? Now? Oh great…' Harry said with a sigh, drinking the rest of the pumpkin juice which was left in his glass.

'The rest of the week doesn't look promising either,' said Ron, 'At least we have double Defence Against the Dark Arts tomorrow,' he added.

'That's something to look forward to, isn't it?' said Hermione thoughtfully. She was eager to find out what they would study this year.

'You're right, Lupin has the most interesting lessons,' Harry said, glancing at his watch. 'We better go to the dungeons now, we got only ten minutes left,' he added.

As the three of them got to the dungeons, they saw Ann standing there, her bright green eyes fixed upon the door, as if she couldn't wait for the lesson to begin. Harry, Ron and Hermione found it strange since not a single Gryffindor liked Potions.

Harry decided it would only be polite to start a conversation after their meeting on the train rather than ignore her.

'Hi Ann,' he said.

She obviously didn't notice their presence before (being used to people's ignorance) and turned around with a little jump.

'Oh, it's just you,' she said, 'I'm sorry, I thought you were someone else. I was just-'

'Well, well, look who we got here' came a cold voice behind Hermione.

Malfoy was standing there, along with Crabb and Goyle at each side, standing like bodyguards.

'What do you want?' said Ron with raising anger.

'I will tell you since you asked me so nicely,' he answered, fleshing a vicious smile, 'I was thinking of starting a Potter fan club, since so many people seem to have an odd…' he paused for a moment, trying to find the right word, 'Interest in you, Potter. People like the stupid Creevys, that fat Longbottom and…who are you?' he said, looking at Ann.

'Leave her out of this, Malfoy,' said Harry. Malfoy looked back to check if anyone (and especially Snape) was coming, only to see Pansy Parkinson going in their direction, a group of Slytherin girls behind her.

'Is that your new girlfriend, Potter?' he said aloud, so everyone could hear it.

Pansy came closer to take a better look at Ann, then (addressing Harry) said, 'I see your taste hasn't changed much, though it did get better since that Weasley.'

'Yeah,' agreed Malfoy, 'Anything is better than a poor Weasley,' he added, and the group of Slytherins laughed.

If it wasn't for Harry and Hermione who were holding him, Ron, whose face was red with anger, would've probably redesigned Malfoy's face.

'You don't want to do that. What if Snape sees you?' said Hermione.

'What's the matter Potter?' asked Malfoy, 'Loss for words? Or you just don't know how to stand up for your poor friend because I simply said the truth?' he added, trying to provoke him.

Given the chance, Malfoy would've continued with his insults, but he simply fell silent when a shadow came upon Harry, Ron and Hermione.

'Any problems, Mr. Malfoy?' said a voice behind the trio.

They turned around and saw Snape looming over them, his black eyes fixed upon Harry in a threatening manner.

'No sir, Potter and his friends were just on their way in,' he replied and then turned to look at Harry, 'Weren't you, Potter?' he said.

'All of you go inside, now. That also includes you, Mr. Malfoy,' said Snape. He waited until they were inside the classroom, closed the door behind him and stood in front of the class.

Ann was the first to come in- she went silently, almost unnoticed and sat at the back of the class, hidden in the shadows. Second to come were Harry, Ron and Hermione, who found themselves a seat in the middle of the class. Malfoy was the last to come inside- he took a seat next to Pansy, who came in earlier along with Crabb, Goyle and the group of Slytherin girls.

At that moment, Snape began what the students called "the beginning of the year speech". They were silent, as they didn't want to get a detention on their first day.

'As you are no doubt well aware, this is a most important year at Hogwarts, a year which will begin to determine your future careers,' he paused and smirked at Malfoy. 'I cannot underline strongly enough the importance of the study of Potions now. Some of you,' he paused again and looked at Harry, 'Are here due to what I believe to be an unfortunate mistake, but let me assure you, this mistake will soon be corrected. This class contains the best. Anyone who is found incapable of brewing a simple potion or following the plainest instructions (he was now looking at Ron) will have to find themselves another N.E.W.T class. I will most certainly not be tolerating neither indolence nor stupidity.'

As he spoke, Ann was listening attentively. For some reason, she admired her professor. Whether it was his choice of words or his attitude, she did not know. But something about him made him interesting to her, and over the past five years she has been trying to solve the mystery that was Snape.

Obviously, she did not think he was a great person. Some things about him annoyed her, things like insulting Harry for example. Somehow, she always got angered whenever he did it, although when she thought about it, she didn't have a reason to.

Once again the usual routine of Potions class and in fact, of every lesson started. Snape had magically written the instructions for their first potion this year using his wand, and began walking through the rows, throwing sarcastic remarks and criticising Gryffindor students. When he got to see Ann's potion, he did what he always did- pass by silently, then go back to his desk on the front and write down notes about each student. Ann always hoped he would say something, since her potions were only second to Hermione's, if not equally good. She had her loneliness to thank to for that, since the lack of a real social life had cleared off most of her schedule, leaving her with plenty of time to study. That's why she was good at Potions- she wasn't a natural as Snape was, but she guessed she was good enough to be in his N.E.W.T class if she got an Outstanding in her O.W.L exam.

As the end of the lesson drew near, Ann looked around her to see how the rest of the class did. The blinding potion she brewed which was supposed to be dark purple, was blue in some cauldrons, and taking a quick glance at Ron's she noticed it was completely black. By the look on his face she could see he felt completely helpless and she wished she could help him.

Meanwhile, Snape finished writing his notes.

'Come here with a sample of the potion unless you would like to get your first zero. However, I have the feeling that some of you will get a zero anyway,' he said maliciously, looking in Harry and Ron's direction.

Ann was the first to come with her sample. She placed it on his desk, hoping that maybe this time he would say something, but he didn't even look at her. Only when she realised she was just standing there doing nothing, she went back to her seat, packed her things and headed outside the dungeons.

Harry, in the meantime, was watching her while bringing his own sample along with Ron. The colour of it was a little lighter than it should've been, but at least it was purple.

'Ron, don't you find her a bit odd?' he asked his friend, thinking he would understand who he was talking about.

'Who's odd?' replied Ron, a confused look on his face.

'Ann. She looks a bit familiar, don't you think?' asked Harry while packing his things.

'Oh yeah, Ann…She does look a bit familiar. I wonder why she's alone all the time, she seems like a nice person to me,' said Ron.

'She's nice,' agreed Harry, 'I really can't think of a reason why she doesn't hang around with anyone,' he added.

'I don't think it's our business. Who knows, maybe there's something we wouldn't want to find out…' replied Ron, 'Anyway, I think we better go now if we don't want to be late for Transfiguration,' he added and the two of them headed towards the door, where Hermione was waiting for them.

Harry's first week at Hogwarts as a sixth year student was more or less the same- classes, homework and weird encounters with Ann in between. He couldn't help but wonder why she always spoke so little and tried to avoid everyone, for he was very curious about her. One of the main reasons was that she reminded him of someone, like he had seen her before, only in an old picture. Of course, he knew this wasn't possible. No one could've taken an old picture of someone his age.

Harry decided to let it go, having a strange feeling that eventually- sooner or later, he would find out who she really is.
