Harry's POV
Time kept flying by, as it usually does whenever you have fan, and even with all the experiments Harry did, he had fun alright.
And now even the end of the year exams have ended, and with tonight being a full moon, he knew it's the night when the Marauder's confrontation, and he wanted a front sit.
The one problem he had is that Lupin didn't have the map, nor was he willing to give something that can be used against him to anyone, which was why, after conversing with the twins and getting their notes in the map he created his own, before burning the map, leaving only the Whomping Willow and the Shrieking Shack.
The map in fact isn't that hard to create, but understanding of its reason of operation is a harder thing to do.
Based on his understanding it works on the basis of energy radiation, like most energies, magical leaves traces, and magical people leave traces that are specific to them, and by connecting a specific name to a radiation you can follow them, it was what the ministry of magic does, but they connect the trace to a wand, and the wand to a person, which is why you can do wandless magic without getting caught during the summer.
The reason the map can trace people around even without the wands and show the names of the people is because of the Hogwarts' magical quill.
The quill, which can detect every magical child's birth in Britain and know their names and location, and while he has no idea how it works, by using a simple spell, it is possible to use its detection ability to create the map.
The only reason no one has created a map for all around Britain is because the quill can't show as much precision on the country's scale, sure it can only show where people spend most of their time and do magic, not where they are currently, but for the castle? No problem.
It took him two days of going around the castle at night invisible, taking photos anywhere, with the exception of the professors and headmaster's offices, before giving them to Gai for it to create the Marauder's Map 2.0 on it, digitized, then it took another night to get to the quill and use a combination of the Protean charm and the point me charm between the map and the quill and use on the map the Homenum Revelio charm in runes to make the map to show the people.
Harry could have made the map just like the original one, only with better map, yet, he decided to take it a step farther, by keeping the map inside Gai, and making an earring connected to Gai by another Protean charm, he created an alarm system in Hogwarts to which he is connected without the need to look, and as the connection is going both ways he can not only ask Gai to search for specific person, but as long as he has an idea for Gai to do, he can say it immediately, not to mention that as the charm has no distance problems, as long as you feed it enough magic, it meant he has Gai with him anywhere he want.
Of course when he explain the twins why he has an earring they wanted one each so they all can talk during the summer vacation, and then Luna wanted one also, which was why Harry now had two earrings, and why the twins were terrified to go home, as they remembered about their mother.
Anyway, it took him a week of preparation to be ready for this, and now he goes to face the one he avoided the entire year- Remus Lupin.
Remus' POV
Remus had a pretty good year.
He had his two friends and their son near him all the time, he managed to keep the job for the entire year without anyone realizing he's a werewolf, and even had wolfsbane delivered to him.
The only thing he didn't manage to get a chance to do is have a meaningful conversation with the one person he wanted the most- Harry.
Harry was such a unique boy, he was quite in class, never raising his hand to answer the questions asked, yet answers correctly whenever called upon, he has no friends in school except for one a year below him, and while he seems to be the number one in the theoretical part of every class, his classmates doesn't seem to really notice him.
He hoped Harry would want extra lessons, as his practicals left much to be desired, yet the boy didn't, he waited for him do something he could give him detention for, yet with the exception of one event at Christmas, as far as Remus can tell at least, the boy was like the perfect student.
In the end, Remus gave up and waited for the boy to approach him, and it seems the wait was finally over, even if he is a bit sad it took till the end of the year.
"Hello mr Peverel, what can I do for you?" He wanted to call him Harry, yet he knew from Christmas he can't force this.
"Hey Professor Lupin, can I ask you a question?"
"If it's about your grade than..."
"Not at all, it's about something else." Harry interrupted him
"Sure, but only if I can ask you one myself." It was his opening with Harry and he won't lose it
"Very well, I found a few weeks ago a piece of what seemed to be a magical map belonging to one wormtail, after asking professor Snape about it he said it was a nickname your friend had, who is he? I want to return it to him."
Remus felt shock, the map he and James were searching for the entire year as a way to catch Black was found by Harry?
"Can I see it? If I'm not mistaken it is one I did with my three friends."
The boy looked conflicted before taking a piece of paper out of his pants, making Remus heart sink.
The piece, small enough to show only the grounds or the last floor of the castle, won't be nearly enough of help catching Black.
Yet, with nostalgia, Remus took his wand out, put it on the paper, and said the words "I solemnly swear I'm up to no good." If it was the full map you would have been able to see the names of the four friends on it, yet this piece only showed Wormtail, and even the W was chipped.
Seeing the name disappear and the map activates, Remus took one look to understand which place was seen, the place he used to spend every month in as a werewolf - the Shrieking Shack, yet what terrified him was finding out that three people were inside, Sirius Black, Ron Weasley and Peter Pettigrew.
All thoughts left his mind.
He no longer thought of Harry, and what question to ask him.
No longer thought about what job should he search for next year.
He ever forgot about this being a full moon.
Only one thing was on his mind- Sirius, Peter.
The names were swirling in side his mine as he knew there must be an explanation for why Peter is still alive, and if he is, why did Sirius went to jail for?
Saying a quick goodbye, Remus ran as fast as he could out side, hoping he would get an answer before something irreversible would happen, barley remembering to cast patronus with a massage for James, it is time for a Marauder reunion.
Harry's POV
Watching Lupin running for the Shrieking Shack, Harry almost felt guilty as he casted a confudus charm on the man as he ran together with him, only with a notice me not charm casted on him.
"You found the map, no one gave it to you, nor did anyone met you at your office.
Yes, he almost felt guilty.
