We don't own anything Harry Potter; it's all J.K. Rowling's.

READ & REVIEW:) This is our first story, let us know what you think!

It was a sunny day in mid-July. The beautiful 16-year-old Aurora Diamond sat on the lawn behind her home, playing with a lock of her long, golden brown hair, while staring intently at the handsome James Potter.

"Come on, Rora. She's just as nasty to you as she is to the rest of us, why do you always defend her? This could be our one chance to annihilate Slytherin and get her back on our side. I thought that was what you wanted..." James pleaded, gazing into her ocean blue eyes.

Aurora sighed and looked at the hair between her fingers. "Fine, James, if you really think this will work... I trust you."

James' face lit up like an exciteable little puppy, causing Aurora's heart to flutter. "Ok, so this is the plan: Tonight, we're going to have a party, I've already invited the guys-"

"Where is this party going to be?" Aurora interrupted.

"At casa de Diamond, of course." Aurora just rolled her eyes as James continued with the plan. "So, the guys are all going to come over and you know Ariel will be furious to see that many Gryffindors in your house."

"Wait, where are you going with this? Are we just going to piss her off? Because you know how she gets when she's angry."

"Relax, Aurora, I've got it all under control. We'll tell her she can invite her friends, too-"

Aurora interrupted again. "Do you really think that's a good idea? My parents will kill us if the house blows up while they're away!"

"Do you really think I'd let that happen?" James asked innocently and continued before Aurora could respond, "When everyone gets here-"

"Wait, who's everyone?"

"Oh, the usual suspects: Sirius, Remus, Peter..." James paused, took a deep breath, then finished, "and Lily."

Aurora raised her eyebrows. "Lily? Are you serious?!"

"Rora, I'm hurt! Even you, girl I've known since birth, can't tell Sirius and I apart?!" James said in an attempt to lighten the mood.

Aurora rolled her eyes. "James, don't change the subject. You know Evans and I don't get along."

"I just thought you two would be able to set aside your differences for Gryffindor. This is Slytherin we're talking about."

"I know what's at stake," Aurora said exasperated, "but it's going to take all of my concentration to convince Ariel we're not up to something. I don't need Evans around distracting me.

"Well, well, well. Aren't you two just precious," called Ariel's taunting voice.

"Precious?!" Aurora laughed nervously. "We're just two friends talking, what's so precious about that?"

"Ok, Peaches... What new scheme are you trying to pull my sister into this time, Potter?"

"Scheme?! Ariel, I'm hurt. Here I am having an innocent conversation with Rora and you come interupt and accuse me of scheming?!"

Ariel rolled her amethyst eyes. "You haven't had an innocent conversation in your entire life, James Potter."

"I have too!"

"Please! You've been getting my sister into trouble since we could walk."

"If you're referring to the incident with the cat, technically it wasn't my fault. I just wanted to see how old Henry would like a shower, you know just a little spritz. He really was a dirty old cat. She," he said pointing at Aurora who looked affronted, "is the one who dumped him in the bath. I had nothing to do with that!"

"Oh, yeah, because saying, 'Dunk him, Rora, dunk the dirty bastard!' had absolutely no effect." Aurora muttered sarcastically.

"Thank you, I'm glad you see it my way!" James said, smiling confidently, folding his arms across his chest.

"You're impossible Potter," sighed Ariel, shaking her head.

"Impossible?! I thought I was impossible," pouted Sirius, as he slipped his arm around Ariel's shoulders. "Impossibly good-looking!"

"No Black, you're delusional," Ariel scoffed gracefully removing his arm from around her shoulders. "What are you even doing here?"

"I'm here to see you, babe," cooed Sirius. Ariel raised an eyebrow, but before she could protest he added, "Say what you like, gorgeous, you'll give in to my charms eventually."

"While you're off in your dream world, can one of you explain to me why this idiot is taking up my valuable time?"

"I'm here for the party, dollface!"

Aurora and James exchanged nervous glances. "She wasn't supposed to find out like this, this won't end well," Aurora whispered to James, climbing to her feet.

"What party?" Asked Ariel angrily, looking at James pointedly. "Just an innocent conversation was it, Potter?" Her voice rising dangerously.

Before James could reply, Aurora, sensing trouble, leaped up. "Well... We were thinking about having a party tonight..." She began, but faltered under her sister's furious stare. "No?... Ok."

Ariel rolled her eyes as she watched Aurora walk back to the boys, before turning to walk away herself.

"Guys, this isn't going to work," Aurora sighed, "she's not going for it."

"You're her twin," James exclaimed, "convince her!"

"Yeah, because this party is happening, so you can either help us or hinder us," added Sirius defiantly.

"Please, Rora, for me?" James pleaded, yet again giving her the look she could not resist.

Aurora sighed, giving in. "Fine... Ariel wait!" She called as she ran toward her sister. Ariel stopped in her tracks and turned to look at Aurora.

"No, I'm not going to have my house overrun by Gryffindors."

"If you would've let me finish, you would know that I was going to say you could invite your little Slytherin buddies, too."

"Please! Those idiots have obviously been rubbing off on you! Getting Gryffindors and Slytherins together under one roof? Do you realize how stupid that would be? Mom and Dad will flip if we get this house blown up! Besides, I don't want to subjugate my friends to a house full of Gryffindors – to Narcissa maybe..." Ariel paused as though contemplating the idea. "No, even I'm not that heartless."

"But – wait a second, what's your sudden issue with Narcissa?"

"I just don't like the way she looks at Lucius."

"What?! Why do you care how she looks at Lucius?! You aren't dating him, are you?"

"No, just innocent flirting."

"Whatever. My friends are coming. So you can either suffer alone or with your friends. We can stay in separate parts of the house and never see each other. Now, if you will excuse me, I have a party to plan. Come on boys." Aurora spun on her heel and stalked off toward the house leaving Ariel gaping in disbelief behind her.
