CHAPTER 2: HOGWARTS' EXPRESS.

September comes and it was time to go back to Hogwarts for my six year. The platform 9 ¾ was quite full; there was some auror there to keep an eye on things. I climb on the train with my trunk to find my friend and a compartment where I could stay. I made some friend over the year at Hogwarts, I tend to keep to myself but there actually some people I like quite much. I think the one I like the most are the Weasley twins and their friend Lee Jordan. I love pranks, and those prankster got a really good imagination they made some amazing things. And more importantly they are not bullies, I hate bullies. I got along with the girls and boys of my year in my house but I don't really have close ties with any of them.

So I was looking for the twins when I passed a compartment. Potter and his friends were in there with another person. An adult, who was sleeping, well pretending sleeping, there was no way he could sleep with that much noise around. Paying no more attention to them I went to find the twins.

The journey to Hogwarts was uneventful until a little after six when the train started to slow down. We weren't in Hogsmade yet, it wasn't normal, the train shouldn't stop right now. My guts were telling me to be on guard, there was something dark outside the train and the temperature around was starting to drop dramatically. The twins and Lee were white as sheet, and I was feeling cold uncomfortable, and unhappy, very unhappy…

Looks like dementors have chosen to pay a little visit of the train. That wasn't good, those things weren't supposed to be in contact with students they were dangerous and they couldn't make a difference between a child and Black. I couldn't let those things wandering around.

I opened the door of our compartment, students were looking in the corridor, the doors of the train were open and the dementors started to climb. That wasn't good. It was time to get control of the situation.

I cast rapidly a sonorous, I couldn't let students approach those things:

Everyone go back to your compartment, and close the door, stay in! Those are dementors of Azkaban! Everyone go back! NOW!

Fucking hell! Fudge was a fucking idiot, dementors on a train full of children, what would it be the next time.

The guardian of Azkaban were starting their search and were slowly making their way down the corridor, I counted twenty of them. That's quite a lot of dementors. I let them looking in the compartment I couldn't stop them doing their job but I was taking a close eye on them there was no way I would let them in.

They didn't take long on the fifth compartment one of them started to enter; well to bad for him I wasn't going to let him. I started to concentrate, putting my occlumency wall at their strongest, looking for a happy memory; I let it go through me casting the patronus charm:

Expecto patronum!

My wolf guardian flew out of my wand at full force, charging the dementors. But he wasn't alone, another patronus was coming from the other side of the wagon, some sort of big dog, a big bad one, that was a powerful patronus for sure, as powerful as mine and that was something. I started to make my way in the direction were it came from. I watch the silver form with some chock. It was a grim.

Well that was unexpected…that was the first time I heard about a wizard or witch with a grim as a patronus. It was kind of hilarious to have the representation of death as a guardian. The man I have seen earlier in Potter's compartment started coming toward me. His eyes were on my own patronus. He was staring at it the same way I was staring at his own patronus.

Well it's quite true that a wolf as a patronus is extremely unusual, the silver wolf is the guardian of my family. I think this is where my patronus come from.

The man was staring at me with disbelief in his eyes.

His eyes.

I couldn't look away. He has beautiful amber eyes, and there was something in his eyes that make me feel… I don't know… it was strange. He got those kinds of eyes that tell you they have seen too much things, they looked old and tired, but there was something else there. There was still some life and hope in it. The man looked dead tired; his closes looked old and worn. He wasn't really in a good condition. And yet he had cast a powerful patronus. It took a lot from a wizard to cast a corporal patronus.

We were standing there, looking at each other, taking in our mutual appearance. There was some raw power radiating from him, he was one of those person who has an aura of some sort. His was powerful, but there was calmness and a kindness in it that was impossible to miss. He still had his wand at the ready, staring at me.

There was more to this man than the eyes let on.

Well; I started; it seems there's no more dementors here Mr.?

The man seems to regain his composure when I started to talk.

Lupin, Remus Lupin, I am the new professor for DADA.

Oh.

And you are?

Oh sorry, Ana Parker, professor.

It's rather unusual for a student to cast a patronus charm, it's quite an amazing piece of magic you just did.

Thank you professor.

Well, I am going to have a talk with the conductor, could you find the prefect and tell them to check on the students?

Yes sir I'll do it.

Fine. Oh and here some chocolate if someone need it.

Thanks professor.

I watch as he left me in the corridor. He didn't seem like a man you wanted to piss off, there was something dangerous about him.

Remus Lupin. One more mystery to solve, my hit list was growing.

REMUS POV

I was tired. Dead tired.

The full moon was just the night before; the transformation had been one of the more painful I had over the years since this night in 1981. I was slightly limping, it seems Moony had decided to pass his frustration on my left leg last night, it wasn't too bad, it was just one more thing to add to the growing list of my injuries.

I was on the platform 9 ¾ parents were saying their good bye to their children and you could heard some owls hooted indignantly here and there. I always loved the rush before the start of the train; and the agitation there always seems to be on the platform, it remains me of older day when the world was still simple and didn't go farther than adolescent's problems.

I was going to make my journey on the Hogwarts Express to add to the security of the train. I was going to teach DADA at Hogwarts for the next year at the personal request of the headmaster. He didn't put it like that but I was pretty sure that he wanted to keep an eye on me because of the evasion on my former friend, Sirius Black, like I was going to help him. For all I know the next time I was going to see him he wouldn't remain in the world of the living for long. That traitor.

If it wasn't for Sirius Black, James and Lily would still be alive. Harry would have had his real parents.

To sum it up, the full moon was just over and I was to be on a train full of hormonal adolescent for seven or eight hours. I think Dumbledore could have find someone better for the job, the students didn't even know me.

Well it's Dumbledore I wasn't going to push him and I didn't really protest either. In fact I was just a bit excited at the prospect of the journey. Fine. A lot excited.

I was impatient to see Harry.

Eleven years since I last see him, all those years I tried to see him I couldn't; Albus wouldn't let me. I had send owl with gift but I had the impression that Harry never received it, I wasn't even sure that he knew who I was. I was a bit bitter on the subject. At the death of Lily and James, I tried to take custody of my pup, but when you are a lycanthrope in the Wizarding world you don't have a lot of rights. It seems that changing in to a best one night in a month makes you a permanent monster the rest of the time.

Finally after eleven years I was going to see Harry, James and Lily's son. How I have missed the little boy.

I was impatient to hold my cub, the last of my pack, I needed him, missed him more than anything.

I climbed on the train to find an empty compartment; somehow I doubted that Sirius Black would be hiding on the Hogwarts Express. I wanted to take a nap before patrolling the wagon and meeting the prefects. I found a place to stay and put my luggage up, and installed myself comfortably near the window for a so deserved nap.

As I drifted off to sleep a few minute after we left the station, I heard the door opening. I stayed still; hopping the sight of an adult sleeping there would discourage the children. It didn't work.

"Who d'you reckon he is?" A male voice hissed as they sat down and slid the door shut.

Bad luck it seems he wouldn't be able to take a peaceful nap. I heard the kids siting down but remain quiet. There seems to be three persons, with some pets. I could smell a cat, I could smell a cat anywhere, an owl by the sound, and something that sting quite much, I didn't know what but I didn't like the smell.

"Professor R. J. Lupin," whispered a girl voice.

"How d'you know that?" ask the first one.

"It's on his case" she replied

That one seemed to be a clever one, the third person had yet to talk, maybe I was going to "wake up" to take a little look.

"Wonder what he teaches?" said the boy.

"That's obvious, whispered the girl. There's only one vacancy, isn't there? Defense Against the Dark Arts."

"Well, I hope he's up to it, said the boy doubtfully. He looks like one good hex would finish him off, doesn't he? Anyway . . . What were you going to tell us?"

Very flattering boy, I'd like to see you try, taking on a werewolf, that would be amusing. Even after the full moon I had a strength a wizard couldn't rival. I remembered a time in my sixth year when James had piss me off just after the full moon; Moony didn't appreciate some comment he made and was very susceptible that day. He never crosses me again after a full moon.

Then the third person began to answer. I quickly realize who it was. It was Harry. My little cub was in the compartment with me! I could feel Moony awake under the surface, he was struggling, he wanted to see his pack brother, and he wanted to feel him.

"Cub! My cub!"

I was surprised, I hadn't heard Moony in years, he was always there in the back of my mind but it had been long since I heard him, like he didn't want to talk anymore.

"Moony?"

"My cub, Moony want to see, Moony want pack!"

"Wait a little Moony, patience, we're going to be pack again I promise!"

"NO! No waiting! Pack now! Before old man comes back!"

"Old man?"

"…"

"Moony?"

I couldn't feel him close anymore, like he was sleeping. But I was stunned, after all this time Moony was willing to talk again. Moony was withdrawn after our pack disappeared; he didn't or couldn't talk anymore. Maybe with Harry here he would talk again. But what did he means by old man? I didn't understand and Moony usually couldn't talk clearly. He was kind of a kid, a pup who didn't grow up with time.

Maybe I could try to talk with the kid, see if Harry recognized me.

But the conversation the kids were having was leading to some personal matter and something was telling me they wouldn't want an adult to hear. I could hear Harry explaining about Sirius Black; it seems Mr. Weasley had warned him, it was a good idea. The first boy seems to be his son, but I didn't know who the girl was.

But Harry visibly didn't know why the guy was after him, in fact he didn't react to my name, it seems that he wasn't aware of who Sirius and I were. It was disturbing. It seems the kid didn't know the whole story. It saddened me that my cub didn't even hear of me until now.

"Sirius Black escaped to come after you? Oh, Harry . . . you'll have to be really, really careful. Don't go looking for trouble, Harry —" said the girl.

"I don't go looking for trouble," said Harry. "Trouble usually finds me."

How often did James use that line? Why didn't it surprise me? With a father like James it was bound to happen that the marauder's gene was transmitted to his son.

"How thick would Harry have to be, to go looking for a nutter who wants to kill him?" said the Weasley boy.

Yeah, a nutter, Sirius was probably insane now after eleven years in contact with dementors, somehow I doubted there was any sanity left in the man.

"No one knows how he got out of Azkaban," he said uncomfortably. "No one's ever done it before. And he was a top-security prisoner too."

Yeah, no one knows young man, and I keep wondering myself. I keep wondering…

I never told anyone that James, Peter and Sirius were illegal animagus, it was a marauder's secret and at the time Balck went in Azakaban it wasn't much of an importance, but now that he was free, my conscience was telling me that maybe I should tell Dumbledore. But it made me feel uncomfortable to tell him that after all those years. I didn't want him to be disappointed in me after all he did for me.

"But they'll catch him, won't they?" said the girl earnestly. "I mean, they've got all the Muggles looking out for him too. . . ."

"What's that noise?" said Weasley suddenly.

A faint, tinny sort of whistle was coming from somewhere. Ah, it seems someone got a Sneakoscope, but it usually didn't react to werewolf presence unless they were threat to someone and I was pretty sure I wasn't a threat so why?

"It's coming from your trunk, Harry," said Weasley, standing up and reaching into the luggage rack.

Is that a Sneakoscope?" ask the girl.

"Yeah . . . mind you, it's a very cheap one," Weasley said. "It went haywire just as I was tying it to Errol's leg to send it to Harry."

Well if it was a cheap one, no need to worry about it… I start to drift off listening lightly to the conversation, the girl seems to have love for books and the Weasley boy remained me of Peter with the way he was talking about sweet. I was starting to wander through my memory of my own journey on the Hogwarts express with my friend when I heard Harry say something that picks my attention.

"I can't go. The Dursleys didn't sign my permission form, and Fudge wouldn't either."

Dursleys; where did I hear this dreadful name? And why wouldn't they sign his permission to go to Hogsmeade? And Fudge what in merlin's name the ministry of magic has to do with all of it?

"You're not allowed to come? But — no way — McGonagall or someone will give you permission —

Harry gave a hollow laugh.

"— or we can ask Fred and George, they know every secret passage out of the castle —"

Secret passage; seems I'll have to keep an eye on Harry if he was anything like his father.

I let the tiredness overtake me and I drifted off again. I should have check the wagons but I couldn't bring myself to care, Moony was still close to the surface, and he and I didn't want to leave Harry. We couldn't after eleven years we just found him. It was already hard enough to have him so close and know he didn't know about me. Or us.

I wake up later in the evening when the light of the train went out after it stopped in the middle of nowhere. I could feel the temperature dropping fast and when I opened my eyes I could see some dark silhouette climbing on the train. There was some shuffling in the wagon as students came in and out of the different cabins. I was immediately alert. Something was wrong. That kind of coldness wasn't natural. It could only be one thing…

I heard a voice in the corridor, someone, a girl by the voice, had cast a sonorous and ordered the students to go back to their compartments.

Dementors were on the train. I could feel Moony rising in me, he could feel something dark coming and he wanted to protect Harry and the children, I could feel him alert and ready to strike.

I quickly stand up when the door open, there was no way I was letting those things near children. I could see Harry in the corner of my eyes; he was starting to react quite badly to the presence of the guardian of Azkaban. I concentrate hard on my feeling of the day, the joy to find my cub again and quietly I cast my patronus charm. The grim came out of my wand. He charged the dementors away. I send him in the corridor and quickly go to check on Harry. He had fainted. I take a quick look at the kid, they were relatively ok, but I had to drive the menace out of the train before I could take care of him properly.

"Take care of him! I'll be right back; I have to take care of those things!"

I stand out of the compartment.

I stopped dead in my track, someone else had cast a patronus, there was a silver wolf charging the corridor, the dementors were nowhere to be seen. A silver wolf. Like Moony. Like me. I've never heard of anyone having a wolf as a patronus. Never. I was dumbstruck.

Who had cast it? It was incredibly powerful; I could sense its magic running all the way through the next wagon. My eyes landed on a girl, a young woman. I was staring at her, she was standing here, proud, I could sense the power radiating from her. Our eyes locked. Oh god, these eyes. Silver eyes. She was standing there all powerful, her long curly blond hair cascading at her side, wand in hand ready to strike, god she was beautiful, and Moony was right there with me, I could feel he was as confused as I was, but there was something else about it, some recognition?

Her eyes were still on me, she was evaluating me. I don't know what her conclusion was but I waked up from my trance when she started talking.

Well, it seems there's no more dementors here Mr.?

Lupin, Remus Lupin, I am the new professor for DADA.

Oh.

Her voice. She casted the sonorous, maybe she was a prefect? But she didn't have any badge. And I didn't know a lot of students who were able to cast a patronus charm at this early age.

And you are?

Oh sorry, Ana Parker, professor.

Ana Parker? Never heard that name before maybe she was a muggle-born.

It's rather unusual for a student to cast a patronus charm, it's quite an amazing piece of magic you just did.

Thank you professor.

Well, I am going to have a talk with the conductor, could you find the prefect and tell them to check on the students?

Yes sir I'll do it.

Fine. Oh and here some chocolate if someone need it.

Thanks professor.

It looked like I already have another student to keep an eye on; this girl must be promising and a powerful witch.

I left her there returning to Harry's side quickly. He was starting to return to the world of the living. He was white as a sheet, he was sweating and cold. It wasn't normal that a thirteen years old boy react like that to the presence of a dementor. There was something wrong.

I waited until he opened his eyes. Those green eyes, Lily's eyes, afraid, there was an apparent terror in his eyes that seems to go deep inside of him. It clearly wasn't normal thing to see in a thirteen years old boy's eyes. It was… wrong. The moment of weakness seems to pass, and I could see that Harry was studying me, struggling with something. I couldn't stop staring, he was so much like James, my little cub, his hair, his nose, and Lily's eyes. I have missed those eyes so much.

"Moo-ey?"

I was dumbstruck. Did Harry recognize me? I could sense Moony's agitation, he was happy, I was happy. I could feel my eyes watering. And I offered my first true smile in ten years to Harry.

"Yes Harry. You remember me?" I asked. I had to know.

"I think I do. It's not really clear, but I think I remember you from a long time ago."

"I was one of your parent's friends Harry; I used to baby sit you when you were still a little baby in diapers."

I heard muffled laugh. I grinned mischievously, how embarrassing for harry talking about him in diapers.

I could see harry blushing. But he offered me a beautiful smile anyway. How I missed him.

"Here's some chocolate, eat it, it'll help you feeling better."

"What was that thing?"

"This, Harry, was a dementor, a guardian of the prison of Azkaban."

"Eat. You'll feel better, and this is for all of you." I said giving the rest of my honeydukes chocolate to Harry's friends.

"Thank you…err"

"You can call me Remus when there's no one around Harry, but I will be teaching you in class, so it will be professor Lupin when we are not in private, ok harry?"

"All right. You knew my parents?"

"Yes harry. I will tell you about them later, for now I need to go check on the other students. We will talk later, I promise."

I get up to live, giving a last longing glance to harry, reluctant to live.

ANA:

I was going back to my compartment when I heard the discussion between the new professor and harry, it seems that Lupin knew the Potters and Harry. So he knew Black too. It seems that I had a new track to explore in Sirius Black case.

"Moo-ey?"

Well it was kind of cute, maybe a nickname. I let them to their conversation, it seems Lupin and harry were very emotional, whatever they were talking about.

I pass the rest of the journey thinking. So if Lupin was a friend of the Potters maybe he knew things I didn't. Maybe I should talk to him. But he believed that Black was a murderer it was not going to be easy to approach the topic.

We arrived at Hogwarts without further incident. The feast was quite uneventful, except for the warning Dumbledore had given about the dementors. A little bit too late if you asked me, we should have been warned beforehand. But Wizards were not always logical it seems.

I was going to wait a little and see how Lupin was, what kind of men he was before I talked to him.
