I solemnly swear that I am up to no good…

"The existence of forgetting has never been proved: We only know that some things don't come to mind when we want them."

It was September 1st and the train station was overflowing with Hogwarts students each running to reach platform 9 and ¾. Amongst these students was a very special boy. A boy who, at just one year old, defeated the most feared and powerful dark lord of all time. A boy who because of this, was famous in the wizarding world. A boy who was famous for something he didn't even remember.

Harry Potter didn't feel particularly special at the moment. He was keeping his head down, pushing his way through the busy crowds. He was thinking of Sirius Black. A mass murderer who had just escaped from Azkaban, and was believed to be coming after him.

It's not that Harry was scared. As far as he was concerned the safest place on earth was where Albus Dumbledore was. No, he wasn't scared, just confused. For some reason unbeknown to him, the name Sirius Black sounded familiar. As if it were a name from an old book, read when he was young. He tried to tell himself that there was no way he could have known Sirius Black and that perhaps the name just sounded familiar on account of having heard it off the television or something. Before he had a chance to ponder it further, he was running through a wall to the platform. Mrs Weasley gave him sandwiches and a hug and reminded him to keep out of trouble. Even though Mrs Weasley wasn't his mother, Harry had always felt that she was the closest he had to one. Harry and his friends Ron and Hermione boarded the train and found a compartment. Little did he know his life was about to change forever.

As they entered the only available compartment, they noticed a shabby looking man sleeping in the corner by the window. Careful not to wake him, Harry went and sat opposite the man and, as Hermione and Ron argued over trivial matters (as they often did,) took his time studying him.

The man had light brown hair which was flecked with grey though he must have only been in his thirties. He had pale skin and laugh lines and Harry couldn't help but feel a strong sense of familiarity with him. He quickly shook off the feeling though and instead told Ron and Hermione about Sirius Black supposedly coming after him.

Hermione then went on to give Harry a lecture on staying out of trouble causing Ron to roll his eyes multiple times and contribute several sarcastic remarks to the conversation. When Hermione had finally finished her rant they all sat quietly for a while. Hermione read her book, Harry sat deep in thought and Ron tapped his foot growing impatient with the long train ride.

"Who do you think he is?" asked Ron, gesturing to the shabby looking man.

"Professor R. J. Lupin," Hermione stated matter-of-factly.

Lupin, why did that name sound so familiar to Harry? Maybe it was just him. Maybe he was being ridiculous. Maybe he did know this man. No, thought Harry, you can't possibly know him. You have never seen this man before in your life. It's just a coincidence.

"Harry, Harry. Are you alright?" He was drawn out of his musings by his very concerned looking friends.

"What," he asked stupidly.

"You were in your own world for a moment there mate," Ron said.

"Oh, I was just thinking," Harry assured them.

"Is this thing with Sirius Black worrying you, Harry, because it's perfectly alright for you to feel worr-" Hermione began.

"No," Harry interrupted, "I'm not worried. Wherever Dumbledore is is safe enough for me."

They sat in silence for the rest of the train ride, until out of nowhere; the train came to a very sudden halt. They couldn't be there yet. They still had another hour at least until they were due to arrive.

Lupin still hadn't woken when the compartment became deadly cold. Frost began to appear on the window and the four occupants of the compartment breath turned to smoke in the ice cold temperature. Harry suddenly became aware of the fact that he felt very depressed, very sad, but he couldn't for the life of him figure out why.

It was then that a cloaked figure appeared; it reached a grey, ugly hand to the door and pulled it open. It was then that the screaming started. It was then that the world went black.

Harry opened his eyes to see Ron getting ready to slap him. He immediately sat bolt upright, narrowly avoiding a collision with Ron's head. He looked behind his two friends to see an extremely concerned Professor Lupin staring back at him. As soon as he met the deep brown eyes of his new teacher, Harry was overwhelmed with a very vivid flashback.

Flashback:

"James," called a flustered looking Lily, emerging from the kitchen. She paused just long enough to smile warmly at her one year old son before shouting back up the stairs again. "Are you ready yet? Remus will be here any minute and I would like to spend our anniversary doing something a little different than waiting for you to stop playing with your hair!"

Harry laughed at his mother's ranting before giving a small yawn. Lily smiled at Harry, not believing that she had brought such a beautiful baby boy into the world.

"Coming Lils," James called back down. "Keep your wig on!"

Lily Scowled. James's comment brought more than a small laugh from Harry however, who rolled onto his back and laughed uncontrollably. Just then there was a knock at the door before his mother came back into the room and kissed her son goodbye. His father did the same.

"Now Harry, be good for Moony, mummy and daddy will be back later. Love you," James said before leaving with Lily.

Harry shifted his eyes to Moony. Green eyes met brown.

End of flashback.

Moony. He was looking at Moony. Harry felt as though he might faint again. He stared into Professor Lupin's eyes, trying to decide if he had perhaps imagined it. Perhaps that creature, whatever it was, caused powerful hallucinations.

He didn't look away from those eyes though and Professor Lupin didn't look away either. Ron and Hermione were looking between the two with confused expressions. Noticing this Harry looked away but looked up again at the sound of a cracking noise

Professor Lupin broke up chocolate and gave Harry, Ron and Hermione a piece. They all sat and ate in silence before curiosity got the better of Hermione. "Sir, what exactly was that?"

"It was a dementor, one of the guards of Azkaban. The driver said that they were searching the train for Sirius Black when I asked." He replied, not taking his eyes off Harry. "Though I can't imagine why. I mean, I think someone would have noticed if Sirius Black was sitting next to them on the train."

They sat together for the remainder of the train ride. During that time, Ron told Professor Lupin that the defence against the dark arts post was jinxed, earning a rather hard smack round the head with a book from Hermione, Professor Lupin told Hermione what they would be learning in his classes this year when she asked and Harry kept his head down, occasionally sneaking glances at Lupin. Harry felt as if Lupin's eyes had burned a hole through his head by the time they arrived at Hogwarts. Harry, Ron and Hermione made their way to the great hall for the feast. And so the year begun.
