Chapter 1: Back to Hogwarts

Lily Evans raced down the corridors of the Hogwarts Express with an official-looking letter clutched tightly in her hand and a maniacal smile on her face. She pushed her way through huddles of squealing girls reuniting with their friends after a long summer, zoomed around a few first years nervously looking for an empty compartment, and successfully jumped over someone's roaming cat before finally reaching her destination at the very back of the train.

A couple fourth year Slytherin boys snickered as fanned herself and wiped sweat from her forehead, but nothing was going to ruin her day. According to the now-wrinkled letter she was holding, she had been made Head Girl! She had received the letter earlier than day, and although it didn't state who the new Head Boy was, she thought she had a pretty good idea of whom she would be working with all year. After boarding the train- after an uncharacteristically long security checkpoint- and catching up with a few friends in other houses, she quickly learned who her partner would be, and could barely contain her excitement.

"It's absurd to choose a Head Boy and Girl from the same house…" grumbled Donald Macmillian bitterly.

"Yes and I can't believe Dumbledore made a Marauder Head Boy… I know there have been attacks and abductions lately, but this truly is most shocking news I've heard all summer! What is happening to the world?!" shrieked Cassiopeia Swoop, a Hufflepuff who had been a prefect with Lily the year before. Lily learned to appreciate Cas's flair for the dramatic during the time they spent doing rounds together the year before, but after a quiet summer, her shrill voice took a little easing into.

"Oh but no offense Lily!" Cassiopeia quickly recovered. "I know you lot are friends... And really out of the four of them, he isn't so bad. Nothing like that Sirius Black…"

As Cassiopeia and Don began discussing all the trouble Sirius had caused over the past few years, Lily quietly excused herself.

She rushed down the train in order to find the boy she who had she had worked with as a perfect all 6th year, the boy who had become one of her best friends, the smartest and arguably most mature boy in her class, and boy she knew would make an excellent Head Boy- Remus Lupin.

Having finally caught her breath, Lily raised her fist up to the opaque window of compartment's sliding door. Before she could knock though, she heard a loud BANG from inside the compartment that jostled the train car violently.

The small explosion knocked Lily off her feet. She now heard loud arguing, laughing, and yelling from behind the door, followed by what sounded like one person tackling another.

Since second year, the Marauders had been "strongly encouraged" by the conductor to claim the last compartment so as to not "disturb" the other students and teachers.

Rolling her eyes, Lily smoothed her skirt, shook out her hair, and knocked loudly on the sliding door.

The boys suddenly went silent. She heard some worried hushed whispering what sounded something like, "Quick, hide the stuff!" following by some shuffling, before Peter Pettigrew yelled, "Come iiin!" in an overly innocent sing-song voice.

She slid the door open.

"Soooo… word on the street had it that the newly appointed Head Boy of Hogwarts is sitting right in this very compartment," he eyes landing on Lupin.

Remus smiled and looked up from the book he was reading, put he wasn't smiling at Lily. "Come on Prongs, you've been talking about it all day, don't be shy now!

James Potter stood up slowly, a wide grin starting to creep across his face.

"We are going to have so much fun this year, Evans!" looking at her with sickening adoration.

Lily felt the color drain from her face and she stared at the Head Boy pin shining brightly on the front of his robes.

"Well, that was rude," James plopped back down onto the seat next to Peter in a huff. Lily's words still echoed in his ears.

"Dumbledore made you Head Boy?! You weren't even a prefect! Oh Merlin, why is this happening to me?!" she let out before exiting the compartment and slamming the door behind her.

"Prongs mate, can you really blame her?" Remus closed his book and looked at James sympathetically. "You two haven't had the best relationship…"

The door flew open again and Lily rushed back inside, her hand held over her mouth and nose.

"Those pre-pubescent Slytherins set off dung bombs in the hallway! Merlin it smells awful out there! This is why I always sit at the front of the train… Looks like weren't stuck together a little longer." She sat down next to Remus, who finally gave up on his book and put it back in his bag.

Lily looked around the compartment. "Where's Black? Don't you all travel as a pack?"

"What?! No, not a pack! It's not like we're animals or anything! Wow Lily, that's crazy. You're crazy!" Peter blurted out, looking around wildly at James and Remus for support. They ignored him

"Off with some girl," Remus replied, a hint of bitterness in his voice. "Marlene McKinnon, I think."

"Why so upset, Remus?" Lily asked coyly, sure she already knew the answer.

"Because he hasn't seen his friends all summer! You'd think he'd want to spend some time with us."

"I mean, I lived with him this summer Moony. Honestly I'm somewhat sick of the twat," James stated bluntly.

"Yeah and didn't you-"

"ARRGHHH!" Suddenly, the train screeched to halt, sending trucks flying off the shelves.

Sirius Black finally emerged from the compartment whose windows he and Marlene McKinnon had been fogging up for the past hour. He was still buttoning up his shirt when a few of his Quidditch teammates filed down the hallway, all high fiving him as they passed.

"You're the man Black!"

A group of Ravenclaw girls looked on, all whispering. He shot the cutest one a wink, and she immediately dissolved into a giggling mess, despite her friends' disgusted, albeit arguably jealous, glares.

Sirius swept his long dark hair out of his eyes, and straightened his tie. "Can you hand me my shoe?" he gazed back at Marlene, who was still sitting on the compartment bench, covered in a blanket. She had never seen someone get dressed so fast.

Marlene tossed him his shoe. "So, maybe we can try and go to Hogsmeade together sometime this term," she looked up at him hopefully with her big blue eyes.

But Sirius wasn't looking at her anymore, something down the hall had caught his attention.

"Yeah sure, anytime. I'll see you later though…" He hurried down the train, a fire starting behind his dark eyes.

Sirius was sure he had caught sight of his younger brother, Regulus, disappearing into a compartment with Snivellus, Avery, and Mulciber. He took his wand out and muttered a spell to unlock the compartment.

"Oi!"

"What the hell do you think you're doing!"
"You are welcome in here, you filthy blood traitor!"

Sirius ignored the three oldest boys, who were all hastily pulling down the sleeves of their robes and pulling out their wands, and pulled his fourteen-year-old brother out of the compartment by the front of his robes.

"What the bloody hell are you playing at, hanging out with that lot?!" Sirius demanded, shoving Regulus up against the window.

"Get off of me!" The younger Black demanded, struggling against his older brother. "You can't tell me what to do!"

The fight was beginning to draw a crowd, as the noise drew more and more students out into the hallway. The two wrestled on the ground. Even though Regulus was a few years younger, inches shorter, and pounds lighter than Sirius, the two looked so much alike that if it weren't for the glaringly different colors of their school robes, it would have been almost impossible for anyone to tell them apart.

"Like hell I can't!" Sirius finally got Regulus into a chokehold. "You think I'm going to let my brother get mixed up with Death Eaters? What, you think you're hot shit now that you started shaving six months ago? My brother isn't-"

"You're not my brother anymore!" Regulus shouted, cutting him off.

Sirius let go and took a step back, stunned. Regulus stood up hastily, his nose bleeding. He looked at Sirius

"You're not my brother anymore," he repeated, practically spitting out the words. The train car was completely silent and everyone watched on, anxiously awaiting Sirius' next move.

The next thing anyone knew though, they were all thrown to the floor as the train came to a screeching halt.
