Author: kakkoii-me

Disclaimer: I dont own the Harry Potter characters or anything...JK Rowling (a genius!) does

kakkoii-me speaking! I had this idea for a while, and I can I just wanted it to elaborate it! so if you (readers) could so pleasingly review or leave a message, i will forever love you! This story is located during Mauraders Era, focusing on Sirius x OC [with a teensy bit of Remus ^^] and James x Lily...! :))

Catastrophe Number One

"Bloody hell," I growled at the staining magenta blotch on my skin – that one was sure never going to leave. I scrubbed my cheek even harder, the dark magenta tinge slowly starting to spread. As I looked at the mirror, my features turned into a menacing scowl. I just had to go in mum's room… I just had to open that book…

"Cassie dear, say good-bye to your brother!" shouted mum from downstairs. Good ol' mum - always calling me when I in some sort of trouble. My eyes quickly scanned my chaotic bathroom counter. I growled again, unconsciously guilty of not cleaning up my messes more often. But then again, what do you expect out of a mere screwed up teenager.

I bit my lip, holding back a smile as my eyes found exactly what I was looking for. Grabbing the scarf without another thought, tightly securing around my neck and making sure it covered everything up to my nose, I shot downstairs before my mum could once again call out my name.

"CAS- oh dear, always the late one – come along now, and bid your brother good-bye; he can't wait forever," with a cheeky smile, she grabbed my shoulders and led me to the outside of our small two floor home, too busy to pay attention to the oh-so obvious scarf tied around my head. Outside stood my twenty year old brother, who shot me a wicked grin, his eyes crinkling with laughter as I stepped out in the front yard.

William and I are so different that sometimes I wonder how we're even related. Maybe it was the fact that he inherited my mother's beautiful genes, by having dirty blond hair and bright sapphire eyes that always seem to hold that extra little smile. Or maybe it was his tall and lean, yet muscular body that was constantly shown off during Quidditch practice, which was regularly ogled by most of Hogwarts' girls with a pair of binoculars. Or maybe it was his true genuine personality that swooned and swayed everyone (professors included) - I really did not know. All I knew was:

He's too perfect.

I remember my first day at Hogwarts – 'Oh, you must be William's little sister! Mellinger correct? My, you're brother – he was something! Top of my class I must say!' That was how all my classes went. Yet, the worse was Potions with Professor Slughorn. Quite clearly, I remember his face lighting up with joy and happiness when he read off my name during my first class of Potions during roll call; he talked proudly on how William was always ahead of class, and how he was meant for a great and jolly good future. But by the end of my first class, I could see just how much of a disappointment I was to him compared to my goody-goody gumdrop of a brother (not to mention all the following incidents happen in that class. I mean what's the difference between stirring clockwise and counter-clockwise? Either way, you're still stirring a bloody soup!)

"Hitching yourself into trouble already Cassie?" he grinned, showing off his pearly whites. I grumbled something under my breath, before crossing my arms, and looked away. Despicable – how dare he leave with such a smiling face!

William sighed, this time the happiness in his eyes gone, and took off the scarf, slowly unrolling it, before pulling out his wand and pointing it to the multiple spots of bright magenta that covered my face. Mumbling a few words under his breath, I started to feel a sort of warm breeze on my cheeks and knew instantly that the embarrassing splotches were gone. I felt my stomach churn in guilt, and I looked down, my hair covering my eyes. I watch my ragged white converse (that now had taken a turn for the worse, and looked exceptionally gray) and kicked a pebble. Just don't look up; I told myself, just don't look up.

I heard a sigh, and I felt his warm big hand ruffle up my untidy bronze hair, a tendency my brother had when he got worried.

"Look Cassie, you know how big of an opportunity this is for me. When the Ministry of Magic announced that only a handful of Aurors were to investigate the death of Madame Roseviere and her family in France, it was only shocking when they picked me – one of the new recruits!"

I frowned, my face still hidden behind my hair. Of course they would pick him. Why wouldn't they? Angrily, I kicked a nearby rock quite hard, as it flew through the air a couple meters away.

"Then why," this time I decided to dig a hole in the ground with my shoe. I pity earthworms – how could one live under the ground forever? "Is Emily accompanying you?"

"Is this what this is all about?" William let out a strained chuckled, and continued, "Come on Cassie, don't get your panties tied in a knot! We're engaged, it's only natural she wants to come,"

Engaged. That word scared me. It meant it was the process of being stuck with someone for the rest of your life. I shuddered trying to think of anyone wanting to be engage with me. I shook my head; no one it their right mind would be engaged to me.

"So if I get engaged to you, then can I come?" I looked up, my eyes pleading him not to leave. I mean who else was going to pester and annoy me? He might be the 'over-achiever', the 'perfect' one, but he was still my brother. No matter how much I envy him, how jealous I was of him, its impossible to turn against a sibling, especially one like William. You always end up liking him! This time, my brother flashed me a real smile, and engulfed me in such a big embrace, that I felt like I was going to explode.

"Stop with all the rubbish Cassie; who would want to marry you anyway?" my brother teased. I chuckled at the thought of me getting married. Again, I repeat, it would be an impossible feat. When we broke apart, he put his hand on my shoulders, and said, with a strict yet teasing voice,

"Now, Cassandra Mellinger, I bestow you with pride, to wish you the best of luck on your fifth year at Hogwarts!" I groaned and rolled my eyes. The nutter; always giving me this speech every year before school started. "As ex-team captain of the Gryffindor's (may I say) best Quidditch team, you, little lady better get a bloody spot in this year's team, you got it? And I don't mean by being a bloody replacement!"

Rolling my eyes once again, I broke away from his grasp, waving my hand at him, signaling him to leave. He grinned at me once again, grabbing the suitcases that were at his side before mock-saluting me.

"And don't go breaking too many hearts!" and with that he Apparated away. After hearing the annoying pop noise, I scoffed and ran my fingers through my hair. As if I had a chance with any of the kids at Hogwarts.

"Get in dear, and start packing! You're leaving tomorrow, so be sure you've packed everything!" beckoned my mum from inside the house. I sighed and stretched my back. As I stepped in, I couldn't help but feel slightly bored. Of all my years at Hogwarts, nothing really exciting happened – well at least not to me; so why should I expect anything different this year?

Oh but blimey was I wrong.

kakkoii-me shutting up! this is sort of an introductory chapter ~ the rest of the characters will show up on the next chapter -devilish grin-. Hope you enjoyed the first installmet, and please Review!
