[REVAMPED]A second chance at life but with what consequences?

It's been a few months since that day, Sirius has realized that his mind from his 36 year old body migrated into his 16 year old body. He has no idea why or how this has happened but all he knows is that it's a second chance. but the issue is that he was placed right after he did the "prank" on Snape, and because of this there's really no one to talk to without them thinking he's bonkers. Remus is just avoiding him and seemingly just hating on him, James is standing by Remus's feelings and is completely shutting out Sirius and Peter is just staying out of it. So Sirius has been spending more time at the library, pondering and researching.

He was researching migrating and how this happened but also pondering: How do i get into my friends good graces? what about my parents? do i still run away or should i stay home this time and see if i can use their influence to change things? can i save my brother?

"SIRIUS!" A harsh yell snapped him out of his trance, which earned said person a harsh shush and glare from Madam Pince. Sirius looked at where the call came from, Marlene and Regulus,both looking a slight degree of concern. Marlene went up to him and crouched down next to him, and all Sirius could do was stare. He never realized how much he missed her. They were never really close but they had always found comfort in each other.

Sirius seemed to just be drinking in her appearance, the way her blonde hair completely shaped her face, her green eyes always looking briefly looked like the actual sea when the light hits it. In Sirius´s time he has never met someone who looked like her. the only person who could come close was the odd Ravenclaw girl, Luna Lovegood, and even then there was a very stark contrast.

Sirius eyes wandered behind her, Regulus stood there. Regulus looked as define as always but there´s something there Sirius never noticed, or rather never bothered to notice when he was mentally 16. He looked..... more tired and maybe even a bit more wary. He had blacker hair than Sirius (Sirius has a more browner hair color) but they both shared the same bluish-gray eyes that always looked so tired, but Regulus's his just looked done, not tired just done with everything. Something depressing to see on a 14 year old.

"What's up?" Sirius asked, trying to see if he could still talk as his 16 year old self but even he could tell that his voice, even if it sounded like his 16 year old self, sounded heavier, more aged, more tired. Marlene just looked at him as if searching, She looked back at Regulus as if asking for something. This somewhat shocked Sirius, In the past they were always at odds, never happy with each other the few times they spoke. In all fairness, Marlene was sometimes like that to him too, he was always cocky and she didn't like that but during 4th year they got closer.

"Sirius, get up." Regulus demanded, 16 year old Sirius would have fought about it, yelling and not wanting to go, but this was different. Sirius got up, looking at his brother with a longing as if he might disappear if he doesn't follow what he said. "We're taking you to the Great hall. You need to eat and get out of this...... funk? you're in." Regulus finished and motioned for Marlene to do something.

That was when Sirius felt himself being lifted up into the air and the next thing he knew they were flying him through the hallways. "why are you two doing this?" was all he asked though from past experiences he knew the answer for Marlene but for Regulus... he never really cared to know why he did what he did, even though he did love him. "Because we care for you! and you hiding out in the library and wherever else you go isn't good for you" Marlene chirped

At the dinner table, it was so weird. the Slytherins didn't like the idea of having two Gryffindors at their table and the Gryffindors aren't happy two of theirs are at they slytherin table but no one wanted to say anything to Regulus or start anything to Sirius because recently both brothers have been snapping at everyone for no reason, for Regulus that's normal but for Sirius it isn't and Sirius snapping at you is way scarier than Regulus. The Ravenclaws and Hufflepuffs are just staying out of the tensions. The Gryffindors are staring daggers at the Slytherins and the Slytherins are staring daggers at Sirius and Marlene.

the teachers also sensed the tension but dinner continued as normal.

Sirius ate as much as he could but he recently he didnt have much of an appetite, he looked over at the Gryffindors, he saw the marauders staring at him, he waved slightly but they just turned away. 'Great it's the fact that i have to re-re-become friends again that's urking me right now' As dinner continued suddenly an owl swooped in and dropped something right infront of Sirius causing everyone to stare, the time for letters was over and usually owls wouldn't be let back in or out until the next day

Sirius opened the letter, with everyone staring at him

"Dear Sirius Black, you might be wondering what the bloody hell is going on, well you see i didn't like the way you were going in life nor your timeline and i decided i'll send you back a couple years, fix your relationships and don't fuck up or else your precious little godson might not be there when you get back
~By your one and only H. G.~"

Once he finished reading, the letter burned. Sirius was in a state of shock, completely out of it. The hell did it mean? What did it want him to do? Mcgonagall was standing behind him "Well what did it say? Must've been important if it turned you as pale as a ghost!" Sirius looked at her and as soon as he opened his mouth he doubled over and threw up and passed out causing chaos within the whole dining hall. Students swarmed the Slytherin table trying to see the Infamous Sirius Black at his worst, Teachers tried to push students back. Regulus and Marlene were Carrying Sirius out of the dining hall while the Marauders were completely confused as to what was going on.
