A/N: First, thank you soo much for the reviews, they were amazing. Second, last chapter was a bit rushed, and for that I'm really sorry, won't happen anymore, I promise. Third, the second chapter will explain (almost) everything about Harry coming to the past to teach his parents and the Marauders. Anywauy, I give you:

Chapter 2: Their Future, My Past

Harry Potter walked calmly through the Castle he still called home. Well, it was actually his first home. He never liked the Dursleys, with their shouting, beating and the chores. He didn't really mind the cooking and working on the garden, he never did, but scrubbing the floor and the walls until it was spotless white was just pointless. At least to him. His Aunt didn't think that way, but he didn't care anymore. He was nineteen, he had graduated out of Hogwarts one year late, only being finally free of classes since the end of term in the same year and now he would return to this Halls as a Professor. Or at least that's what he expected. However, things were never what he expected. He just didn't count this meeting as something that could turn into something unexpected. He simply didn't know how wrong he was.

Professor McGonagall had sent Harry a letter a few days earlier asking him to meet her in her office. As Headmistress, she had inherited Dumbledore's office. Surprisingly to everyone, except maybe Harry, Snape hadn't changed a single thing on it, so the first thing she had made was collect all the stuff Dumbledore had on his office and guard it in a small box with an engorgement and a concealing charm placed upon it. Harry suspected it was the former Headmaster's idea, since McGonagall had proclamed, quite loudly, actually, that she couldn't work with all that stuff making noises and puffing smoke in irregular intervals. Harry was almost certain the portrait of the Headmaster was supressing his laughter when it occured.

To clarify things, when this argument between the Headmistress and Dumbledore, he was discussion his return to school after his year hunting Horcruxes with Ron and Hermione and the infamous Battle of Hogwarts, The Final Battle or any of the other names people were calling it. He wanted to get his NEWTs, Hermione also. Ron just tagged along, like he always did. Almost every person who knew he was going back to Hogwarts thought it was to complete the Auror Training honestly, like all the Trainees. Only three peoples, excluding him, knew the real reason why he did that. These people were Ron Weasley and Hermione Granger, or should he say Weasley (they had married in the end of the year) and Ginny Weasley, Ron's sister.

You see, the reason he wanted to come back to Hogwarts was to have something like a normal school year. Well, as normal as you could get being The Boy-Who-Lived-Again-And-Defeat-Voldemort-The-Worst-Dark-Lord-Of-The-Century. He snorted. He was just somebody who had a prophecy and the destiny of the world thrust upon his shoulders because of a prophecy made before his birth by the Divination Professor, who only made two real prophecies in her short life. Harry felt his rage coming back at full force. He took a deep breath, it wouldn't be nice to blow Hogwarts on the 1st Spetember. Trelawney was dead. Because she made a prophecy. Lord Voldemort himself killed her in the Final Battle, just while he was watching Snape's memories, minutes before he went down and Voldemort 'killed' him. Actually, Voldemort killed himself, though he'd never knew about it.

But back to the matter at hand, the letter Headmistress McGonagall sent him was simple. It asked him to meet her on the 1st September on the Headmaster's office, a little before the Welcoming Feast's start. She didn't say anything, just an enigmatic P.S. that seemed strongly like something Dumbledore would write. Harry just shrugged and waited, anxiously, for the day to come. He couldn't sleep the night before, and when he did, it was restless. He woke up with dawn, as he was acostumed since his fifth year, when he started training on his own, and went for a run. He then did his workouts and practised duel a little with Ginny. Ginny was his partner when came to training, but she started one year later because of her age. He was living in his ancestral home, Potter Manor, with Giny, Ron and Hermione, since the Final Battle. The Weasleys dind't want to stay at the Burrow, because it was really crowded, and Hermione didn't have anywhere to go before she got her parents from Australia, so they all agreed to live with him. He was relieved, he would be very lonely in the Manor without his friends, not counting the constant vistis Mrs. Weasley or other Weasley would pay tem everyday. Not that he minded, added him.

Then he had a simple, light breakfast which Ginny cooked, since it was her time. When he finished, Ron and Hermione were just finishing their workout. They chatted for a while, but Harry soon got up and got dressed so he could meet with McGonagall. Then, he apparated to Hogsmead and started walking to Hogwarts, his mind somewhere else, while his feet led the way automatically. He had made this pat so many times he didn't even had to think about it, not once.

He suddenly stopped. Someone was following him. He whirled around, his wand aready on his rigtht hand, while his left was outstreched so he could fire spells with the wand and without. He was quite proficient with wandless magic, as was Ginny. That was the reason their training was different from Ron's and Hermione's, since they couldn't do it at all. He then heard a barking sound and relaxed.

"Hey Padfoot!" he said brightly "You can come out you oversized puppy!" Just then, a small black dog, also known as a Grim, appeared from the shadowns on Harry's left and bounced on Harry, who fell to the floor, laughing, while the dog likced his face. "Ew! Stop it, it's gross!"

He forcefully removed the dog from his belly and throwed it lightly to the floor, where he imediately turned into a man.

"You know, Shadow, you seemed like a five year old there, asking me to stop." He said, his eyes twinkling with mirth and mischief. Shadow was Harry's nicknames, since he could blend into the shadows easily.

"That was the purpose, my dear Godfather," Hary's emerald eyes were twinkling more than his Godfather's. Said Godfather stuck his tongue at him just like a spoilt five year old.

"Spoilsport," he mumbled. Harry grinned.

"So, Padfoot, care to accompany me to the Headmistress' office? She sent me a rather criptic letter and I wanna know what the fuss' all 'bout."

"Sure, cub. Take the lead." And so they went, chatting animately, a complete contrast to the silence Harry did when thinking, sice his own footsteps didn't even making a single noise. Years of practise, he'd always say. Soon enough, they were in front of the gargoyle that led to the office. Harry grew nervous, all of a sudden. "Here's where I leave you, cub. Good chat." He winked and went away. Harry had the sensation he knew what was going to happen. Almost regrtting it, he said the password to the gargoyle.

"Hogwarts United." Then he climbed the stairs and knocked on the door. Something that would change his life, forever, thoguh he dind't knew it, yet.

Hogwarts, 1st Spetember 1977, Welcoming Feast

Harry Potter, or Harry Porter for the time being, almost fell on his face when dropping in front of the Great Hall. His trunk fell with a soft thud behind him. He took the year-turner that was hanging loosely on his neck, transfigured it into a Muggle man necklace and oppened a button of his white polo shirt. He looked at his robes. They were wrinkled from the travel. He sighed and unwrinkled them. He passed a hand on his messy jet black hair, messing more with it, then spiked it. It didn't appear so messy spiked, and it didn't cover his eyes, so he preferred it that way. He pulled a cloak and pulled the hood so it was covering his face. He heard Dumbledore saying:

"Now, I've got one more thing to tell you before we …" he took a deep breath and oppened the door, slighty stronger then necessary and stayed in the shadows until they were all in position. He smirked and walked to the Great Hall. The Hall, as one, stopped breathing. Then he remembered that with the cloak, he appeared to be a Dementor. They were all waiting for the effect to happen, but when it didn't, they all breathed once again. It reminded Harry of his last duel with Voldemort, while they were mocking each other. He felt guilt. Those people were dead because of him. He quickly pushed his somber mood away, returning to face the Headmaster that was coming in his direction. He leaned on the wall.

"Well, what a reception..." he started, teasingly. He made sure to seem comfortable, even with all their wands pointed at him. "I was expecting something more joyous, or at least some sign of relief, I mean, this type of receptions are to Moldyshorts and his minions." He sighed qhen no one moved, except the Headmaster, who was now staring intently at him. He felt the brush of Legilimency. He casually blockd the Headmaster, it wasn't time for it, not yet. " But that's not the case." He shifted. "So, anybody's gonna ask me who I am?"

Dumbledore cleared his throat. Harry wasn't intimidated. He'd won a duel against the old |Headmaster more times than he lost. But it could be because he was older. He pushed this thought to the back of his mind. It wasn't time to guess if he could beat the 20-years-younger Headmaster, was it? "Who are you?" Asked the old man. He just smirked. He thanked the Gods he'd pulled the hood on before entering the Hall. And he just loved to tease the Headmaster. "I, Albus Dumbledore, Headmaster of Hogwarts School of Witchcraft and Wizardry demand you to tell me who you are." He said, now oredering him. He leaned off the wall and sighed, again. he seemed to be doing that really often, he thought, amused.

"Don't need to be so harsh on me, Professor. I'll tell you who I am. I'm Harry, Harry Porter." He said, faking being hurt by the old man's world. He was enjoying himself.

"What are you doing here?" He was back to his kind, caring, old Headmaster façade.

"I was hoping you've already figured out, but well..." He mumbled, then pulled his hood off. There was a sharp intake of breath, which made him fight a smirk. He had hoped this kind of reaction from the students, that's why the cloak. But he'd already had his fun, so he turned to the Headmaster and said, in a business-like tone. "I'm here for the Defense Against the Dark Arts teacher position."

"But you're too young!" shouted one Ravenclaws. He smirked, finally! The Ravenclaws were the ones always wanting to study, to be the best ones in class and everything.

"Wanna duel to see if I'm capable?" He asked. He was itching for a duel, though he'd already duelled more than two straight hours with Ginny. "By the way, I'm nineteen."

"Mr. Porter, if you are so eager to duel someone, maybe you could try it with Professor Flitwick, what do you think?"Asked the Headmaster. The old coot, always trying to resolve everything without violence! He was quietly seething. It was one of the things in Dumbledore that irritated him like hell. While the students stood there, gob smacked, he piced his wand and turned to the diminutive Professor. This is going to be fun. He nodded. Dumbledore conjured a stage and put a barrier so the students couldn't be hit by stray spells. When everything was ready, both wizards quickly went in position. Harry with his hand loosely on his side, feet spread shoulder-wide and left hand ready for wandless magic.

"With or without swords, Mr. Porter?"

"With." was his only response. He quietly summoned Grffindor's sword from his trunk, carefully tranfiguring it so Dumbledore wouldn't recgnise, while Flitwick sported a goblin-made word. He looked at it, was beautiful, but his word was his. Just his. Only Ginny could wield it, nobody else could. The sword didn't let them. They bowed and the duel was on. Harry didn't even try to tire himself, just reflected everything the Professor send to his opponent, eventually launching a curse or jinx of his own, nothing serious. After three minutes of this, he was bored. He quickly took the offensive and two minutes later he had his sword on the Professor's neck, his wand pointing to the small wizard's heart. The Professor's hand was on the floor. After the shock passed, the whole Hall clapped and he was almost deaf when it ended, but content, he'd earned even the Slytherins' respect and that was a something to be reckoned, he clearly knew it. The Hall was quieting.

"Indeed." Said Dumbledore, effectively silencing the Hall. "It seems, at least to me, that we have a temporary Defense Against the Dark Arts teacher, meet temporary professor Harry Porter." Harry bowed to the room, glad to find he at least had the temporary position. Everybody started clapping and cheering, again. Merlin, this kids surely have lungs, thought Harry, amused. Dumbledore, knowing they would spend some time cheering, quickly put the Hall back to its normal way. When everybody was seated once again, He stood up, back in his Headmaster position. "Well, this was exciting. Now, I'm sure everybody here is hungry..."

"Bloody right you are!" Shouted the younger Sirius Balck. Harry fought back a laugh. He was so much like Ron, even more at seventeen. Lily smacked him in a Hermione-like way. he was finding increasingly hard to not laugh. It was just, amusing, even more so when Lily said "Sirius, language!"

Seeing that almost everyone was laughing, Harry gave up and laughed so ahrd tears of mirth were threatening to spill. He was sure that if he wasn't sitting, he'd be in the floor, laughing. When everybody was paying atention again, Dumbledore continued. "So, as Mr Black so avidly pointed out, everybody should be starving, so … Tuck in!" And the Feast started. By the end of it, Harry thought he'd be deaf for the rest of his life.

"So, Harry, what is your experience as a teacher?" asked Minerva McGonagall when the dessert had just appeared.

"Well, I taught a DADA group when I was in my fifth year because that year's teacher was really incapable. It was like I was born to be a teacher. Then, in my sixth year, I taught a close group of friends some Auror kind of training, something I was doing since my fifth year. When I graduated, I was planning to be a Professor, but where I studied, VMA, was without any empty positions, so I followed the Auror carreer, though I'd start my training this year. But then I heard that Hogwarts was in need of a DADA teacher, so here I am." He said, passionately. Minerva could see this young man, though young, could be a very good teacher.

"I see," she answered. Dumbledore stood up. "Well, good luck with the teaching, specially the Slytherins." Harry just nodded, focused on DUmbledore.

"I think that everyone is satisfied and rather tired. At least I am." Harry chuckled silently. It was so like Dumbledore. He'd missed that on the only Welcome Feast he'd had where McGonagall, or Minerva, was the Headmistress. "So, I will not hold you back anymore. Prefects, lead the first years to the Common Room. Head Boy and Girl, please stay behind for a bit. Everyone else, dismissed." Evevrybody got up and went to their towers qith the Prefects showing the first years the easiest way to rememeber. When Harry was going through the doors, Albus stopped him.

"Mr. Porter, I'd really like to talk to you about your qualifications. Could you please answer some questions?" Asked Dumbledore, clearly wanting to finish this earlier. Harry pretended to think for a while.

"Sure, Sir. You can start asking your questions." Harry noticed James and Lily there and hastily added. "I'll be brief, and then later we can meet and I can show you my CV." Albus nodded

"What are your parent's names?" Harry almost flinched.

"Anthony Porter and Carla Swan. Though my foster ones are Katherine Rodriguez and Leo Rosriguez." (A/N: sorry for that, but I'm definitely not the most creative person in the world) He replied, offering his parent's made-up names. "I'm muggleborn. My dad worked in the Microsoft company and my mum was a sort of researcher, but she'd worked as a doctor for most of her life. I lived here in England until I moved to Canada when I received the VMA letter, thoguh I continued visiting England every summer until my sixth-year, when my parents were killed by Death Eaters."

"After I finished my sixth-year and became of age, me and two other friends who had their families murdered by Death Eaters decided to miss the school year and capture those who killed our families. One year later, we were finisehd, so we returned to the school, that's why I graduated one year late. I was top of my class in Defense, second in Charms, Transifguration and Potions. Got an O in those four, E in Herbology and Care of Magical Creatures and an A in Astronomy." Dumbledore nodded.

"Okay, just one more request, please show me your left forearm." Harry complied. He heard Lily suck in a breath and knew she'd seen the scar that Wormtail's knife had left after the graveyard. Harry used to joke with it saying it was his Mark in some sort of creepy way. He then remembered he couldn't exactly tell him how he had received this scar. His brain worked furiously, searching for an answer whilst Dumbledore searched for any kind of glamour. "Mr. Porter, may I ask how did you get this scar?" Asked Dumbledore when e as finished. Harry nodded.

"Well Sir, when I was fourteen, me and my parents moved from one neighborhood to another. One day, I decided to explore. I was lost when I found a graveyard and it already was twilight and the sky was darkening fast, really fast. I started to run, trying to get out of it before it was too dark to see. I tripped in a root and hit my forearm in a sharp rock. It was like thata that the man who took care of the graveyard found me, twenty minutes after I fell. Since my parents were both Muggles, i went to a Muggle hospital and they put twenty stitches and it healed, but it left a scar and even the school nurse in the VMA couldn't make it disappear, so it's 'till now." He explained. Lily looked like she would cry. Dumbledore seemed to catch on it too.

"Thank you for the explanation Mr. Porter. Could you please leave you Curriculum in my desk on my office. It's on the sixth floor and the password is Ice Mice." Harry nodded. "Thank you."

Harry walked out of the Great Hall and to the Headmaster's, Headmaster not Headmistress, office automaticaly, in the same fashion as he had done in the same day before he 'd received the news.

"Harry, I know you are wondering why I called you here." Asked Minerva McGonagall. Harry just nodded. "Well, it wasn't exactly me who called you." Harry raised an eyebrow, calmly.

"It was me, my boy." Said Dumbledore's portrait. Harry looked up, startled. "You see, we are in need of a Defense Against the Dark Arts teacher." He raised a hand, stopping Harry. The raven-haired boy was confused. Remus Lupin and Sirius Black were the Defense Against the Dark Arts theachers. He looked up as Dumbledore continued to talk. "I know we do not need a teacher for that position Harry, but you are not going to teach in 1999. No. You are going to teach in 1997."

Harry sucked in a breath. 1997 was his parent's and the Marauders seventh and last year. McGonagall spoke. "I remember the teacher that year. Made quiet an entrance, actually. Duelled poor Filius and won, actually. He was respected by all the students, including the Slytherins, who respected only their Head of House, and sometimes not even he or she. When Dumbledore asked his name, his reply was 'my name's Harry, Harry Porter'. I never forgot it. He was muggleborn, his parents were killed during his sixth year and he skipped his seventh to revenge them. He had a curious lightining shaped scar on his forehead and a scar on hi sleft forearm, like someone cut a big wound with a knife." Harry was schocked, it could only be him, the scars included. "He was a master dueler, as I've said and once I saw him without a shirt. He had another scar, this one in the shape of a locket of some sort in his chest. He tainted Tom like no other, and he didn't even get hit in the two duels he had with him. He was amazing. Many students wanted to be just like him. And he was born a teacher and a leader."

"You see, it is you, as I guess you have already figured out." He looked at something like a time turner who was where Fawkes' perch stood. "If you don't want to alter te future, I suggest you go home and pack everything you will need. You'll stay there for one year. come back in three hours, top." Harry nodded and disaparated in the spot. Minerva looked at Albus, who just shrugged.

Three hours later, Harry was staying in front of the Headmaster's desk once more. Minerva handed him the thing that was so much like a time turner. "This, is a year turner, something me, Albus, Filius ad Severus were working for years. It takes you back years, just like the time turner takes you back hurs. You'll need to turn it back twenty-two times so you'll appear in 1997. If anthing goes wrong, you ask someone the year. You just need to turn back or forth the difference of years. Any questions?"

"And the others? Ginny, 'Mione, Ron, Paddy, Moony, Dora? Won't they be worried?" He asked. Minerva and Albus shared a look.

"You can write a letter for them if you want, but it will have to be short. You can not, and I repeat, can not tell them where you are." Harry nodded, picked some parchment, quill and ink and wrote a short note telling them he was okay, that he wasn't kidnapped by Death Eaters and that he would return in exactly one year. He dried the ink and handed it to Mineerva. "Okay, now turn it twenty-two times and you are off."

Harry did it and he was being pushed and pulled in every direction. Then, he was in Hogwarts again.

"Ice Mice." He told the gargoyle. He looked around the office. It was almost the same, only without Severus' and Albus' portraits and less slver trinkets. He produced his Curriculum apparently out of thin air, put on Albus' desk and got out. it would't do any good relieving memories whilst the old wizard could enter his office any time. He petted Fawkes, who thrilled a joyous note and got back. When he was halfway back to his quarters, he heard someone. He hid in the shadows and heard them. Probably under the invisibility cloak, he mused. He hid in the shadows and watched.

"Shh, Padfoot, we're almost there!" Said James

"Why? There's no one here!" Replied Sirius

"You'd never know, Padfoot. Remember that the Map's with Filch. We're never certain there's nobody in here." Said Remus. "Now, transform into Paddy and follow us."

Sirus did what he was told. Harry, using the shadows, followed them. They were going to the Kitchens. An evil smirk appeared in his face and a twinkle appeared in his eyes. He would prank the pranksters. They stopped at the portrait of the fruits. A hand appeared and tickled the pear. It giggled softly and they entered. Harry waoted until he was sure they were all too engrossed in talking so they wouldn't hear him entering. He got out of the shadows and tickled the pear. It giggled again and he entered quietly. It was times like this he thanked Dumbledore for his training, though he still didn't like the meddling old coot. He walked to the table where the Marauders were and said, in his best Flich-like voice.

"Well, well, well, we have students out of bed. What do you think, darling?" Their faces were priceless. James and Sirius jumped and spread all thacards around the table and the floor. Remus just turned around, sensing he wasn't Filch and winked. Harry just looked at him, though it was the confirmation he needed, he as pranking the prankster. Peter screamed like a girl and tried to hide under the table. He just burst out laughing, Remus following a few seconds later. The rest looked at them like they were some abomination. Or some kind of God, thought Harry. "Hm, I think I've pranked the pranksters." He commented after regaining his composture. The Marauders just stared at him, shocked.

"What? No, welcome to the group, no, Merlin he's really good? Nothing?" He asked, faking hurt in a way the twins would be proud. "I'm schoked."

"B-bu-but you're a Professor?" Stutered Peter.

"What if? I'm only nineteen, for crying out loud. I'm allowed to have some fun, y'know." He said. "And I think quite a few of those Professors down here were pranksters in their time at Hogwarts. Including Minerva and Dumbledore."

The teens just looked at him, still without the ability of speech. Well, Remus had, but he didn't want to break the 'magic'.

"Well, I'll go now, when you've recovered your ability of speech, come visit me in my office. It is the same as the last teacher's so you won't have a problem finding it. Just please, only during the day, if you have something to say to me at night, I'll visit you." And he disappeared through the portrait, his cloak billowing in a maner Snape would be proud. Remus burst out laughing, again.

When he was sure he couldn't be heard, he burst out laughing, again. It was so much fun, pranking the pranksters. And te Marauders were ten times more fun because they were just hilarious. The twins would recover soon, since they already knew Harry and Ginny were pranksters, but the Marauders... They were another story, and he made a note to try and prank them more.

That day, he was asleep before his head hit the pillow, something that only happened when he participed in a battle. Time travel leaves you exhausted.

Hogwarts, Headmistress' Office, 1st September 1999, After The Welcoming Feast

Ginny Weasley burst into the Headmistress' Office, not even bothering to knock on the door and looked around. he portraits were all up because of her entrance, and the Headmistress wore a Dumbledore-like expression. This infuriated the redhead much more.

"Where is he?" She asked. She knew they knew where he was. She was actually almost certain they were the ones who asked him to disappear.

"Calm down, Ginny." Answered the Professor.

"Calm down? How could I calm down when my best friend, partner and only company just went missing!" He asked, in a calm, deadly voice. Minerva gulped inaudibly.

"Take a seat, and I'll explain it for you." Ginny complied and looked at the witch. "You see, we were in need of a Professor in 1977."

"So you sent him there. Okay. Why?"

"Because there was a Professor that year, named Harry Porter, thoguh his complete name was Harold Anthony Porter that was Harry himself. He trained his parents and the Marauders, except for Pettigrew-" she spat the name "to be the best Aurors since Mad-Eye."

"I knew Harry was good, but never this good. It's not a surprise then that he and I turned the best Aurors since Mad-Eye and the Marauders." she mused "I understand., but can I go there too? I can help train them!" She said in an innocent voice that made Minerva's heart melt.

"Not now, my dear. You'll have to wait until the time is right." Answered Dumbledore's portrait. Ginny almost put the portrait in fire.

"When is the right time?" She asked, impatient.

"You'll receive an owl." He answered. Ginny got upand walked out of the room

"Merlin, Alubs, these kids are quick!" Cried Minerva. Albus just nodded.

A/N: Yes! Chapter two! Sorry about the Ginny part, it's horrible, I know, but I didn't have anything else to put and I wanted a 5k Chapter, so i had to improvise. I hope this one's better, but don't kill me if I have any spelling or grammar errors, I suck at them. I'll try to post next Chapter until next Sunday, but I won't promse anything 'cause I'm gonne travel suring the weekend 'cause I have my cousin's party to go and I have to wear a specific dress and I'll try it. Well, that's it, hope you liked.
