A/N: New story I've been thinking about for a while and I couldn't resist! One reason I started this story is because Regulus is my most favorite Slytherin apart from Draco. Another reason is because I never really thought of Regulus as the really evil type, and I really wanted to change that. One more reason is because I couldn't get the name 'Hayden Smith' out of my mind. Believe it or not, the whole story just came from thinking of that name.

So I really hate to keep writing a Disclaimer for every single bloody chapter, so this is the Disclaimer for the whole story:

Disclaimer: If my initials were J.K.R, they would stand for Jackass, Klutzy and Ridiculous.

The Sirius Side of Regulus

Chapter 1: Annoying Siblings and Relatives

Hayden Smith was a cheery eleven-year-old currently looking for an empty compartment on the Hogwarts express. She had just received the letter three weeks ago, and her parents were more than happy to let her attend. She had straight dark-brown hair with blue highlights (spell practicing mishap. Won't come off), bright blue eyes and full lips with a pointy jaw. Anybody who saw her would know that she would grow up to be a beautiful girl.

She couldn't find any empty compartment, but spotted one with only one boy at the end of the train. He had black hair that was a tad bit shaggy and gray eyes. He was already in his school robes and was resting his chin on his palm, staring out of the window blankly.

"Hello," said Hayden timidly. "Can I sit here? Everywhere else is full."

The boy smiled slightly and nodded. "Sure."

She went in and closed the door behind her. They sat like that for a few minutes.

"I'm Hayden Smith," she said. "I'm a first year."

"Muggle-born?" he guessed.

She nodded. He sighed.

"What's wrong?" she said concernedly.

"My family...we're sort of against mud- muggle-borns," he told her. "It's...a pure-blood thing."

She frowned, not liking the sound of that.

"Why?" she asked. "From what I've read, every family must have had muggle blood one time or the other. Besides, my aunt's a witch, so I'm no stranger to prejudices."

The boy continued to stare at her. She got up.

"Well if I make you uncomfortable I can leave," she said haughtily.

"No!" he exclaimed. "No, it's okay. I do want some company, since my pathetic excuse of a brother won't be with me." He said that last part bitterly.

"Why not?"

"Because I, unlike him, wish to uphold the family name," he informed her. "My brother was the only one ever sorted into Gryffindor in my family, which is practically considered betrayal." he frowned. "But his way of thinking about the world is much better than my mothers."

"Such like?"

"Well, he isn't prejudice, unlike the rest of our family. He's actually hanging out with a blood traitor and-"

"Why are you using the term 'blood traitor' around me?"

There was an awkward silence.

"Right," Regulus said hastily. "Sorry about that. It's just that I'm so used to using the terms at home that-"

"That's no excuse," Hayden scolded him. Merlin, she had a bit of a temper. "The next thing you know you'll be calling me mudblood."

He looked at her, startled. "How do you know that term?"

"In case you didn't hear me just now, my aunt's a witch," she told him, arms folded across her chest.

"Sorry." he took a deep breath. "Look, I'm hoping that we could just be...friends."

He held out a hand for her to shake. She looked at it suspiciously for a while before taking it.

"So what house are you hoping to be sorted into?" he asked her.

She thought about it for a moment. "Gryffindor, but I suppose Ravenclaw wouldn't be too bad. There's no way I'm going into Slytherin, seeing my blood status and all, but I assume you want to end up there?"

He nodded. "I want to make my mother proud."

"And avoid the stream of Howlers that you would get if sorted into any other house?"

He looked at her wearily. "Do you always talk this much."

"I am known for my charm, yes," she joked, and the mood lighten. "But honestly, do you really want to go there?"

He thought for a moment. "I don't know," he said finally. "I mean, it's important to uphold the family name, but the way Sirius talks about his house, sounds much nicer than what I've heard about Slytherin. And I'm not really prejudice, it's just the way I was brought up."

"Saying your brother's name reminds me, you haven't told me about your name yet," she said.

"I'm Regulus Black," he said, slightly taken back by the look on her face. "What?"

"Y-you're a Black?" she spluttered. "My aunt says that the Blacks bring the wizarding world a bad name."

He smiled darkly. "We were told that once or twice. Tell me, what's your aunt's name?"

"Aunt Jessica, mother to James-"

"Potter!" a screech came from the doorway. The two exchanged puzzled looks before opening the door and checking out what was going on. They spotted a red haired girl covered in green goo, green eyes narrowing at a certain laughing boy with messy black hair and hazel eyes, his cronies laughing along with him.

"Oh Evans," the boy said, eyes gleaming maliciously. "You should have seen the look on your face-"

"Get over your big head already!" she shrieked at him before stomping back into her compartment and slamming the door.

"My my, she seems to have a bit of a temper," said Regulus into Hayden's ear.

"Tell me about it," she muttered back. "That's the James Potter I was telling you about." She pointed at the boy with the messy hair.

Then another boy about his height with shaggy black hair and gray eyes came and grinned at him. "You got her good, James. I never thought that green would look so good on her."

Regulus growled at the sight of the new boy. "That's Sirius," he told Hayden in a not-so-friendly tone.

Her eyes widened. "The bad brother? Why is he hanging out with James?"

"I don't know, nor care," he said shortly. "Come on, let's go before-"

"Hello, Hayden!" James came towards the duo. He nodded curtly towards Regulus. "Black."

"Jamiekins, watch who your calling here!" Sirius scolded him. Hayden cracked a smile.

Another boy, with sandy hair and more scars on his arms than Hayden ever thought possible, rolled his eyes. He went over to Hayden. "I'm Remus Lupin, nice to finally meet you, Hayden. James has been bragging about you for weeks."

"Yeah, you never told me your muggle-born cousin was this hot," joked Sirius. "Even for an eleven year-old."

"Now now Sirius, don't get any ideas," said James, joining the joke as Hayden turned pink. Regulus's eyes flashed menacingly. He'd appreciate if his brother would just leave him and his new friend alone.

But of course not, because, as Sirius put it, it's an older brother's job to torment the younger sibling.

"So why were you talking to Reg?" asked Sirius. Ah, and here the teasing starts.

Her eyes narrowed dangerously. "None of your business."

"Watch it, Siri. Hin here has a bit of a temper," James told her. Hayden scowled at the sound of her old nickname.

"Wow, I'm so scared," said Sirius in mock terror. "James, help me!" He went and hid behind James, who rolled his eyes.

"Honestly James," hissed Hayden, putting as much venom into her voice as she could. "if you have nothing to say, I'd appreciate if you would leave us alone."

And with that, she slammed the door in front of them, leaving them dumbstruck outside. Hayden could hear Remus saying, "Told you not to pick on first years, Sirius..."

As they heard the voices of the annoying trio trail off, Regulus breathed a sigh of relief. "Thanks. I don't really enjoy being in the company of my deluded brother."

"No problem. I don't really like being with my prat of a cousin, either." She sat back down. "Although he doesn't usually act this way. Just when he's in front of a crowd, or something. I'm usually the main victim."

"I know what you mean," said Regulus darkly. "You should see the way my brother argues with my parents at home. It's torture."

Hayden stared interestingly at Regulus. She never would've thought to find a Black like this. The way her aunt described the Blacks, she thought that they were evil, that they were the bad guys in a fantasy movie, but the witch in Rapunzel. She never thought about the...feelings one could have, the upbringings at home, the influencing family members. But from what she could see from Regulus, they weren't half bad.

Then again, if Blacks like Sirius were hanging around with prats like James...

She put a hand on his. "I'm sorry for whatever that goes on at home. I hope that we could be friends."

He smiled hesitantly and nodded. He was thankful for this new friend of his, even if she was a friend of Potter. He really wanted for her to be in Slytherin, and hoped that the Sorting Hat would make an exception, but the chances were...

"Less than zero," said Regulus flatly when Hayden asked him what were the chances of her getting into Slytherin. "Why would you want to go there, though? I thought you wanted to be a Gryffindor?"

She smiled faintly. "Yes, but I don't want to start school without my new friend, even though James would kill me. I would say it's worth it, seeing as I'm very shy."

"Really? You had no problem asking me for a spot in this compartment just now."

"That was different. You don't expect me to keep lugging my trunk around the train, do you?"

The duo chuckled. They started talking about random stuff. Regulus was telling her about his family's recent trip to France, and showed her a few pictures from his trunk.

"You mean the pictures actually move in the wizarding world?" said Hayden, eyes widening at the picture. She saw a middle-aged man with his wife, staring coldly at the camera while Regulus and Sirius hovered behind them. "This is so cool."

Regulus chuckled. "If you think this is cool, wait until you see Hogwarts. I hear from my brother that they hire a troupe of dancing skeletons to dance at every Halloween feast."

"Skeletons?" she gasped. "And I thought that the goblins at Gringotts were shocking enough!"

He chuckled again. "From what I hear from my family, there's going to be a lot more than that."

Their conversation moved on from the Black's trip to France to the special things in Hogwarts to Quidditch. Regulus was having a little trouble describing the rules to Hayden.

"But how are you suppose to hold a ball or a bat on a broom in mid-air?"

"It's alright. You won't fall off if you keep a steady grip and lots of training. I want to try out for my house team as soon as possible."

"Why not you just try out this year?"

"First years aren't allowed to play. They think that it's too dangerous."

"Oh come on. From the looks of you, you're definitely someone they'll want on their team."

Regulus's cheeks turned pink. "You haven't even seen me play."

"I don't have to to tell you that you're awesome."

His cheeks turned even redder. "Thanks."

"Anything from the trolley, dears?" a middle-aged woman said from outside their compartment.

Regulus and Hayden went out to take a look at the sweets. Hayden's eyes lit up like she'd just scored a dozen free ice-cream coupons.

"Whoa! These sweets look so different! Irregular! Wicked!" she laughed in delight and bought a bit of each. Then, they went back into their compartment and started swapping sweets: a sugar quill for a liquorice wand (A/N: is that how you spell it?) and other stuff. Suddenly, the compartment door opened again, only this time to find a woman with blonde hair and a sullen face,staring moodily at Regulus, not even acknowledging that Hayden was in the room.

"There you are," she said in a falsely-sweet voice that didn't touch her eyes. "I've been looking all over for you. Cousin Bella is looking for you."

Regulus sighed. "I'll be there in a moment."

After the door closed, he gave her an apologetic smile. "That was my cousin, Narcissa Black. She's a fifth year Slytherin. Bellatrix is the same age, only thing is that she's more fierce and insane."

"Insane?" Hayden raised an eyebrow.

"Yea, you wouldn't believe how she acts at home." He started to get up. "Anyway, I'll see you in a bit." and left the compartment.

Hayden stared after him. Then, as if her body was acting at its own accord, she followed him.

Regulus went into the second compartment from theirs. Hayden leaned against the wall, trying to hear what they were saying. She was curious to hear what the Black family usually talked about.

"...hanging out with a Mudblood. Regulus, have you no shame?"

She froze. That was the voice of the blonde hair girl, Narcissa Black.

There was an audible sigh. "Cissy, can we get to school before judging muggle-borns?"

"Muggle-Borns!" There was a high cackling laugh that Hayden assumed was Bellatrix. "Look, Cissy! Our Regulus has gone all soft on them!"

"I have not!" said Regulus indignantly. "This one is just...different. Besides, what do muggle-borns have against us, anyway?"

There was a loud SMACK. Hayden winced as she imagined Bellatrix's hand strike across Regulus's cheek.

"You shall not speak to me like that!" she shrieked. "Your mother told me to protect you while you're here! That you don't take the same path as your pathetic excuse of a brother!"

"There's nothing wrong with Sirius!" yelled Regulus, and Hayden was glad that he was fighting back. "And there's nothing wrong with Hayden, either!"

"Regulus, she is a Mudblood. She's related to a family of blood-traitors. There is no higher shame to the wizarding world then what she is now! Don't forget, when the Dark Lord gains power, they will slowly be slaughtered one by one!"

Hayden shivered. She had heard about this evil mad-man called 'Lord Voldemort' which is slowly rising to power and will rule the wizarding world. She hadn't known that he was going to rid the world of people...people like her.

"I just hope that he will spare her," Regulus said quietly.

Another SMACK went across his face.

"Bella," warned Narcissa.

"Regulus Black," Bellatrix was breathless. "you barely even know this girl. She is the carrier of the filth that runs through her veins. Do you want to be a disgrace like your dear older brother Sirius?"

Feeling like she's heard enough, she stormed back to her compartment, which was now mercifully empty.

She was thankful that Regulus was putting up a fight for her, even though he just met her, but she couldn't believe how brutally his family members treated him. Now she understood why Aunt Jessica had said that the family was pure evil.

Regulus came back in five minutes later, rubbing his right cheek. He smiled weakly when he saw Hayden sitting there, face pale. "You eavesdropped, huh?"

"I'm sorry," she sniffed. "I didn't mean to, but I...I was curious."

"It's alright, everybody does that sometimes," he said soothingly. "It's just...I don't want to be a disgrace, like my brother. I want...I want to uphold the family name."

But then, to Hayden's amazement, he shook his head. "But not like this! Not where everyone has to be prejudice against muggle-borns and blood traitors! Not where I have to call people like you Mudblood." he spat that word out. "You're too nice, Hayden. You don't judge me immediately, like other people do. You didn't even do anything to hurt me. All you are is just-"

"-a Mudblood," she finished for him. He cringed.

"Don't call yourself-"

"-it's alright. I've had too many people call me names that I'm just not bothered anymore." she shrugged. Regulus bowed his head apologetically.

"But what are we going to do when you get sorted into Slytherin, and I get sorted into Gryffindor?" she asked in a barely audible voice.

Regulus sighed. "I don't know."

"You should bloody well know," Hayden snapped. Regulus raised his head in the surprise of her changed tone. "We are not going to let our houses turn prejudice against each other! Agreed?" she stuck out her hand.

Regulus smiled slowly. "Agreed." he took her hand and shook it. "And we say hell to the people who judge against it."

"Exactly," she said.

"SLYTHERIN!" screamed the hat.

Regulus swaggered over to the Slytherin table as the students there cheered, glad that they haven't lost another Black to the likes of Gryffindor.

"Excellent, Regulus," said Lucius Malfoy as Regulus sat beside him. "Excellent."

Regulus smiled weakly, but kept his eyes on Hayden, where she was still waiting nervously for herself to be sorted.

The list went down until Professor McGonagall finally called, "Smith, Hayden!"

Hayden walked slowly to the stool and put on the hat.

Well well, Muggle-born eh? the hat said in her mind.

No, I'm Jewish. Hayden rolled her eyes mentally. Just sort me already.

Well, I must weigh my options, must I not? You would seem like a fine Slytherin, but due to your blood status, you can't.

Oh. Well, I was hoping that I'd be an exception.

And disappoint your cousin? He's watching you, you know.

Hayden glanced at the Gryffindor table and indeed saw James Potter staring at her hopefully.

Fine, she grumbled in her head. next best to Slytherin?

"GRYFFINDOR!" the hat shouted, nearly breaking her eardrums.

Do you really have to be that loud? she thought annoyingly. Nevertheless, she made her way to the Gryffindor table, where the students there were cheering and whooping. She went and sat next to James, who was beaming at her.

"I knew you'd make it," he said in her ear. Sirius, Remus and Peter were also beaming.

She smiled, but it faltered quickly when she turned and saw the crestfallen look on her Slytherin's friend's face.

But don't worry, she told herself. We won't let our houses affect us, and hell to the people who judge against it.

And with that reassuring thought, she started eating with that smile back on her face.

This is set for Regulus's and Hayden's first year, you work out the rest of the ages from there. I'm planning to have one story for one year, like Harry Potter =) And that is SURE to be true, because I have really high hopes for this story.

GUESS WHO WATCHED HARRY POTTER AND THE DEATHLY HALLOWS YESTERDAY? ME ME MEEEEEEEEEEEE~!
