Invisible existence-a harry potter fanfic

Chapter 1- I dont like the train

My breathing quickened as I stepped closer and closer to the Hogwarts Express. I wiped my sweaty palms on my jeans as I started to hyperventilate."It's going to be alright' I muttered to my self, just over reacting as usual, Potter. I scowl at myself mentally. "Follow the plan and nothing will go wrong." As I said this out loud I looked down to a large scruffy dog for reassurance. Sirius, sensing my  anxiousness, looked up and forced his head into my hand for me to stroke. We were very early, too early if you ask me, so we went into a deserted waiting room.

Sirius quickly and very swiftly transformed and gave me a hug."You can do this Morgana," he said softly. "Remember what I told you, when your on the train don't go looking for Harry, go into a empty compartment if you can, find Professor Lupin."

"Sirius, it's the 4th year of school for me, everyone will of made friends and I'm the only one whose joining the year late. What if i don't understand the classes? What if they had more practise?" I say with a sigh. I knew this was the bottom of my fears, rejection.

"Morgana Isabel Potter how many lessons have you had preparing this? You are 2 years ahead, you have the same skill as an auror" Sirius whispered in my ear. He was right after all, i was personally trained by Mad Eye Moody and Professor Dumbledore. Of course, since i wasn't in school it was illegal  to use magic outside of a wizarding school but  Dumbledore made a deal with the ministry, very private, only the minister of magic new about me.

I took another big breath and nodded. It was time for me to face my fears. The train was enormous, and the station was filled to the rim with teary parents and excited kids. The noise was overwhelming. Soon I spotted him, crowded with a large family of redheads. Two of the redheads, definitely twins, glance at my direction and caught me staring. simultaneously they both smirk at the same time making me go a light shade of pink.

Before going in, I hugged Sirius goodbye, who had now transformed back into scruffy black dog form. I found out that as entered the carriages, to my delight, it was even more crowded inside. Yay.

I could tell that trying to find professor Lupin in this mosh pit of kids was going to be a pain in the butt and so was trying to get an empty compartment. So i ditched those brilliant ideas and tried to find a compartment  with kids that did not look like they were a) going to bite my head and b) smell.

I pushed and shoved for what seamed an age until I stumbled into a compartment. At that point I couldn't care less who was there so I sat my ass in a seat and that's when I noticed that there were three people blatantly staring at me. 

"Hi.  I guess your sitting with us then. I'm George Weasely. " I look up to see the two red headed identical twins that had caught me staring and a brown haired boy all with bemused smiles on their faces. I took a deep breath looking at the twins, my eyes are definitely not complaining that's for sure, i think to my self.

"Sorry, I hope you don't mind, my name's Morgana. Morgana Hartley. " I lie quickly. "No problem Morgana, I'm Fred Weasley, and this is Lee Jordan." says the other twin.
