I own the story, the characters belong to J.K
Eleven years old Sirius stood in front of the three sixteen years old guys with a scowl, he was about to go to the train and now he was... Confused, the one with glasses called someone but none of the other two answered, they were looking at him, as if they were expecting him to react, but the black haired just frowned even more.
-Pads? Are you okay?
-Prongs, it's obvious he's not okay, he's a child!- The pale one shrieked, Sirius, started to panic, and did the only thing he knew, he acted like Mother and Father had taught him, like a Black.
-Who are you?- the voice of the kid was cold, showing no emotions at all, the marauders looked at him in surprise.
-Stop playing- the "Prongs" boy complained, the other two were, well, just wordless, the little boy stood there with a superiority pose showing that he wasn't joking.
-I'm Remus- the eleven years old boy did not show any kind of recognition.
-Peter- the fat one spoke for the first time.
-James, Sirius are you kidding? We've been your best mates since we were children, we are the marauders, how is it possible you don't recognize us?-
-James- the boy remarked the name with sarcasm- I don't have any idea of who are you or your friends, how you know my name or why I'm not in the train already, but when Mother finds out, you three will be in trouble.
Yes, Sirius Orion Black was a child again with no memories of his entire life after the train of Hogwarts and all thanks to a joke to Snivellus that had gone wrong, very wrong, maybe it wasn't the best idea of all to prepare a potion without all the ingredients or mixing another random stuff in it, such as chelidonium minuscula, befuddlement draught, confusing concoction, erumpent potion and forgetfulness potion, but it was the first prank of the year, it had to be perfect, all was settled even before they stepped in the train, of course, they didn't counted that Bellatrix Black would known of the fact that Sirius just ran out of his home and that she would like a little revenge in the name of all the Blacks that Sirius had disappointed, so when the time came, she and her friends disarmed the marauders and instead of being Severus the one drinking the potion, Sirius ended, well, like a child, no one knew that fact, other than the three, because his cousin did not stay for that long, but now, they were, well, in trouble, and a big one.
-Oh for Merlin's sake- James complained.
-What are we going to do?- Peter said in desperation.
-We are so dead- Remus was about to cry when the little Sirius talked to get the attention of the three that were now panicking.
-Do you want to be helpful? I want my stuff, tell me were it is, and maybe we could all forget about it- the three nodded in resignation not knowing what else to do, because in any time, after all, the train would go.
When the four were in the train another problem appeared, the robes of Sirius were big, enormous for a little child like his own eleven version of him, so after a discussion were the kid exasperated took his things and left, they felt, bad, his best friend was probably having the worst day of his life and they all were behaving like complete idiots. Another doubt stood with them in the moment they realized that the robes had no gryffindor sign, yeah, the day was going perfect, perfectly wrong.
While the marauders were fighting about who would get the new size of his robes, Sirius became exasperated, this guys didn't know to do anything? He took his things and left, he started to walk in the train looking for some prefect that could resize his stuff when this blond guy collided with him, they both ended in the floor and with venom the blond said.
-Look where you walk.
-Me? You should be the one looking for glasses blondie.
-Don't you know who I am?
-I should ask you the same question.
-You insolent, I'm Malfoy, Lucius Malfoy- A superiority look appeared in his face and the black haired laughed.
-I'm Black, Sirius Black- And with that said the other boy started to laugh as well, because they were pure bloods and then they didn't have a real reason to fight, just like that.
-So, what are you doing? You don't have a compartment already?
-No, but I actually was looking for a prefect because the size of my robes are wrong -Eleven years old Lucius seemed to understand and nodded.
-One is looking for quality and people just don't do their jobs good enough. You can borrow one of mine while you find a prefect- Sirius accepted- And if you are looking for a compartment, me and my friends are over there- the blond noted one in the end of the train- I think your cousin Narcissa is there too, we'll be expecting you- And with a smirk, the blond started to walk again, Sirius went to change his clothes for the robe of Lucius, he felt more comfortable with something in his size and walked searching for a prefect, but then again, the James boy appeared, Sirius frowned.
-Sirius!
-What do you want from me? Look, I don't have idea of who are you, but my friends are waiting for me, so anything that you want we can solve it in the castle. Good morning sir- And with that Sirius stormed away from a very hurt and sad James.
-How did it go? -Asked Remus, James just denied and the three of them sat quietly thinking about their best friend.
-Bloody train, bloody prefects, bloody James, bloody marauders...
-Black!- Sirius turned to see Lucius standing in the compartment that he was looking for but totally got lost, the blond smirked when the annoyed boy asked.
-Having fun Malfoy?
-Lots, come with us.
-Haven't found any prefect yet.
-We have some slytherins of fifth grade, maybe they can do something to your robes- Sirius nodded and walked inside the compartment while Lucius patted his back.
-Guys, this is Sirius Black, here is your cousin Cissy, Crabbe, Goyle, Greengrass, Avery, Carrow, Rosier, Parkinson, and Snape over there- the dark haired boy looked at young Sirius with surprise, what were the marauders planning now? To infiltrate a member in their lines? That was low, he exchanged a look with Carrow, both of them really confused with this- And he has a little problem with his robes, they are, big, so any of you can change them to his size?- Carrow nodded in confusion and changed the size expecting the prank to fall in and... Nothing, Sirius just smirked and sat with Lucius, Avery and Rosier, talking about quidditch, Narcissa looked at Sirius and when her cousin just stared back, she asked worried.
-Are you feeling okay?
-Yeah, I'm good Cissy, thanks.
And that was it, they went to the boats, for the first time Sirius wasn't with the marauders and the worst haven't come.
James, Remus and Peter stood worried about Sirius, he could get lost, he could fall to the lake, he could not get out of the train, a lot of things crossed their minds but when the black haired appeared with Malfoy, Avery, and Rosier laughing and joking the four of them like best friends, oh, how it hurt. So when Snape came with a really confused look in the eye he just won a "Get lost Snivellus" from Remus and Peter but James, he screamed, like a mad man, because this prank was terrible, awful, he didn't like it at all.
-THAT WAS SUPPOSED TO BE YOU, YOU GIT, THAT WAS MY FRIEND, YOU TOOK HIM FROM ME, YOU'LL PAY SNAPE, THIS WON'T STAY LIKE THIS, I WANT PADFOOT BACK- Remus and Peter did pull him back because he was causing a scene and they needed to talk to Dumbledore to know how to get their friend back.
All the students entered to the castle and the new years were called to be sorted, Minerva Mcgonagall started to say the names while the marauders were really nervous.
-What if he is not sorted in gryffindor? How will we talk to him then?
-James, you are been melodramatic, yes, we saw Pads with Malfoy but his a gryffindor in his heart.
James nodded but when he saw Carrow in the slytherin table, the smirk when he saw Sirius and how Sirius smirked back, he wasn't that sure.
-Black, Narcissa- the blond girl sat and in a second the hat was screaming "Slytherin", the slytherin table was celebrating big the new part of the slytherin family. She sat and smiled at his cousin while Sirius was being named.
-Black, Sirius- all the people was in complete silence when the boy sat, mostly because the face of Mcgonagall when she saw that was no joke, she looked at Potter but the teen was concentrated in the hat that was about to say the house of his best mate. When she put the hat in Sirius head, the only thing that the kid had listen was this.
-I already said what house you belong, of course, in that time I think I was between two houses, I also remembered that you begged to put you were the Potter guy was, do you think this time I can do my job correctly? And choose the other one?
-If by correctly you mean slytherin I'm okay with it, and if not I think you should think it twice.
-Fine, fine boy, after all, that was the other choice. SLYTHERIN!
The hat was pulled off, and the house clapped,some of the students were celebrating like if it was a big deal, screaming things to the gryffindor table, he saw with pride how the house was welcoming him. For a minute he could saw the entire gryffindor house in silence.
And then, started the chaos
