First Encounter

Sirius was finally relaxing. He was on the Express on his way to Hogwarts and, contrary to what he had been expecting, he had already made a friend. It had been a bit shaky at first since the Potters were known Light wizards while the Blacks were the exact opposite, but James had just asked him if he was like his mum, Dorea Potter, or all the other Blacks.

Sirius had been quick to assure him that he was nothing like the rest of his family. That he was like Dorea and quite proud of that fact.

After that, James had been quick to accept him, something for which Sirius was grateful. He had feared he would be shunned by everyone but the usual purebloods because of his name. It came as a relief for him to realize that wasn't the case.

A knock on the door brought both boys out of an intense conversation on the merit of dung bombs and both looked up to see a red-headed girl poke her head in and smile at them.

"Hi," she greeted them chirpily. "Can my friend and I sit here?"

"Sure." James smiled. "We have plenty of space."

Sirius just nodded, not really happy to be sharing his first friend, but the girl at least seemed friendly. More importantly, she didn't look like any pureblood his family would associate with, which meant that she probably wouldn't end up in Slytherin.

"Great!" she grinned and yanked the door open, pulling a boy with her into the compartment.

Sirius couldn't help but frown slightly when he saw how shabbily dressed the boy was. Sirius was an Heir to a pureblood family and was used to have the best of everything. His parents would disown him if he walked around in such clothes. He caught James' eye and knew the other first year was thinking the same thing.

"I'm Lily," the red-head introduced herself, looking as if she would vibrate right out of her skin in her excitement. "This is Severus." She pointed at the sullen looking boy who had taken a seat beside Sirius. "We've been friends since forever! He was the one that told me I was a witch."

"How didn't you know you were a witch?" Sirius asked, looking at the girl incredulously.

"She's muggleborn, you goof." James grinned at Sirius.

Sirius eyes widened slightly. A muggleborn? He had never met one. His mother had never allowed him to socialize with anyone aside from certain pureblood families. He took a closer look at the girl, trying to see if there really was a difference between them as his family had told him so many times before.

"Is that a problem?" the boy sitting beside him snarled, and Sirius could see him gripping his wand.

"No, just curious, is all. I never met a muggleborn." Sirius admitted.

"What House do you want to be in?" James asked, and Sirius threw him a grateful smile. He had felt quite uncomfortable with how they were looking at him. He could practically hear what the raven haired first year had been thinking. It was what most people thought about his family. He would never understand how his family could feel so proud to be called pureblood fanatics and Dark Arts experts. How that could be a good thing in their eyes he would never know. Did they enjoy being shunned by the majority of the Wizarding World?

"Severus told me about Slytherin," Lily said, a smile lightening up her features once again.

"You won't want to be a slimy snake," James stated, a frown appearing on his face.

"Which House do you want to get into?" Severus sneered. From what Sirius could see it look as if that was the boy's default expression. How such a cheery girl and sullen boy could be friends was something that astounded him quite a bit. Maybe he had put her under a curse?

"Gryffindor, where dwell the brave at heart!" James grinned. "It's the best House!"

"The best if you value brawn over brains," Severus snipped.

James jumped up from his seat, his wand appearing in his hand.

"Watch what you say, you slimy snake! My family has been in Gryffindor for centuries!"

Sirius stood with James, ready to defend the first person that hadn't cared about his name. His first friend.

"Yeah, Snivellus, watch what you say." Sirius took his wand out as well, only to have Lily jump in between them.

"That was rude!" she snapped a fierce scowl marring her features. "Apologize!" she demanded and both purebloods looked at her incredulously.

"Why should we?" James asked. "He was rude first!"

"You called him names!" she glared at Sirius, making him snort. He had seen far worse glares than that.

"Nothing that he didn't deserve," Sirius replied, a smirk forming on his lips. "Nothing that isn't true either. Just look at him; where did he find those clothes? Did he pick them up from a garbage bin?"

"Come on, Severus." Lily threw them one last glare before turning around and marching out the compartment. Severus sneered at them, two angry red blotches painting his cheeks, and followed after her, slamming the door shut behind him.

"Well, we certainly won't be making friends with them," Sirius remarked falling back on the bench he had been sitting on.

"Who cares?" James waved his hand carelessly. "He's just a slimy snake and she's a goodie two-shoes. Who would want to be friends with them?"

Sirius laughed and nodded. Yes, who cared about those two?
