A/N Hi guys! This is Casper! I'm graduating in May as an engineer and my semester is exceptionally easy! So I have a lot of time and plan on trying to finish some of the stories I started and stopped while busy in the past few years! If this story gets noticed and people want me to finish it then I will move it to the top of my list!

Disclaimer: I do not, sadly, own any part of the Harry Potter universe! Katherine and Isabelle are all mine but sadly that's it!

Edit: I put up these stories just to see if people were interested! Now that at least a few are I'm fixing the format of them! When I wrote them they weren't designed to go online! Thanks to all who read these before I fixed them!

I looked out the window at the lush rolling hills of, were we in Scotland yet? Shrugging I decided that it didn't matter. Wherever it was, it was pretty. I looked across the otherwise empty compartment at my twin sister Isabelle. Come on Kat, you've been putting off this conversation for the last hour. Gather some courage and say something.

"Hey Izzy?" I said my voice cracking a bit. She glanced up from the Transfiguration book that she had been reading since we left Platform 9 3/4. "Yeah? What's up?"

"Well. It's just. No matter what, we'll still be us right. You promise you won't hate me?"

She looked slightly surprised at my uncharacteristic hesitancy. "Kat, why would I ever hate you? You're my other half. We're Kat and Izzy. You're the yin to my yang.." She trailed off then as if realizing the underlying cause of my fear. "Houses."

"Houses." I confirmed.

Her face softened a little at my confirmation, "Kat. We haven't even been sorted yet. You don't know for sure what's going to happen."

"I know you better than anyone. I know when you're lying." I responded with my usual snarkiness. "Me and you have a lot in common except for one major thing. You are nicer to people that you don't know. I'm not. That quality is going to keep us apart."

"You're not mean!" Izzy replied adamantly.

I just looked at her. Waning slightly under my nice try look she amended her statement.

"Well, not to me."

Chuckling slightly I responded "Well I like you."

She shook her head at me disapprovingly, but the effect was negated by the slight smile on her face. Just as she opened her mouth to say something else the door slammed open.

"Oi Fred, in here." A tall red headed boy called out into the corridor as he stepped into the compartment. He turned around and seemed surprised to see Izzy in the compartment. "Oh bollocks, there seems to be someone in here Fred."

I was surprised when an identical red head walked into the compartment "Good job you idiot, we were looking for an empty compartment." His eyes opened dramatically when he spotted me "Oh Georgie boy. Am I seeing double!?" The red head apparently named George turned around and clasped his hands to his chest and cried out "Oh no. Devils spawn. Please don't hurt us."

Izzy opened her mouth to say something when we heard a shout from down the corridor, "I'm going to kill those twins. That's the last straw!"
I looked at the two boys in our compartment and saw them about to panic. I was enjoying watching them flounder but of course Izzy decided to say something.
"So I'm assuming they're after you?" The boys just nodded and bent their heads together obviously trying to come up with a solution to their problem. I saw Izzy look at me as if saying 'Come on. Figure something out.'

I glared at her in response, but after a moment stood up and addressed the twins while gesturing towards the corner closest to the door on the side opposite the side the door opens on.
"Sit in that corner and don't speak, I'll handle this."
They opened their mouth as if to object but Izzy interrupted them.
"I'd just do as she says. If she has an idea, it'll work."

They look conflicted but then apparently decided that they didn't have a better plan. I stood near the door and took off the jumper I was wearing. As the door to my compartment started to open I slammed my hand on the door
"Excuse me! What do you think you're doing? I'm changing in here!"
The boys on the other side of the compartment turned bright red.
"Why are you changing already. We're still about 4 hours out?"
At this point my mind raced for a suitable lie, coming up with one, I let my voice quiver "Wait, you mean we're not almost there?! But, these two boys stopped by the compartment and told my sister and I that we should get changed now."
The boys lit up at my response "were they skinny red heads?" they asked excitedly.
I nodded and replied "Yes, then they went that way." Pointing down the direction opposite where the boys in front of me had gone. At this point I let my lower lip start to shake as if I was about to cry and shakily said "Why would they lie to us?"
Thinking that they were about to have a crying 11 year old on their hands, they quickly turned and ran down the direction I pointed. Closing the door with a smirk I tugged my jumper back on and turned back to my sister and remarked
"Too easy. They could've at least made it interesting." I sat back down and looked at the twins before saying "You're welcome by the way."

They were staring at me with their mouths wide open before they addressed Izzy
"Is she always like that?"
With a laugh Izzy replied "Oh yes, she was always able talk her way out of trouble."
I quickly interrupted "Oh please, don't act all innocent. You were the one getting us into trouble. I just don't fancy being grounded to our rooms; or worse, classes with Madame Pinchfort. Etiquette lessons were the worst." I finished with a shudder. Our argument drew to a close when the two boys stood up and proclaimed
"Well, we like you guys. Twins, always a plus, troublemakers, an absolute necessity, and the ability to get yourself out of sticky situations, a happy surprise." Confused Iz responded
"A necessity for what?"
"Us being friends of course!" One of the boys responded before introducing themselves "I'm Fred Weasley and this is my brother George."
Iz stood up to shake their hands "A pleasure, I'm Isabelle Herondale and this is my sister Katherine." I nodded in response before chiming in "But we mostly go by Izzy and Kat."

We spent the rest of the train ride with the Weasley twins. We learned that they were in Gryffindor, at least she'll have good people with her, loved causing trouble, and loved Quidditch, I mean what's not to love? I was surprised how fast the time went by, we were the middle of an intense exploding snap tournament when a prefect came by and told us we were almost there. We said goodbye to the twins and just as we changed into our robes, we pulled into the train station. We got off the train and saw a very large man walking towards us calling out for all the first years. We were directed to get into a boat and I found myself in a boat with Iz and another set of Indian looking twins. At least we won't be the only ones this year. I went to say as much to Izzy but found myself speechless when we passed around a corner and saw Hogwarts for the first time. What mother and father said didn't do it justice.

All too soon the boat ride was over and we were directed into the castle and up the stairs where a stern looking woman peered out at us from behind her spectacles.
"In a few moments you will enter this hall and join your classmates. But first you must be sorted into your houses. They are Gryffindor, Hufflepuff, Ravenclaw, and Slytherin."
I noticed her slight distaste as she said Slytherin, that's slightly unprofessional of a Professor. My musings were quickly interrupted by the woman speaking again.
"Your houses will be like your family. Earn achievements and you will earn points. Any rule breaking and you will lose points."
She turned around into the Great Hall and left us outside the large double doors.

As soon as the doors closed behind her I heard a voice call out "So it's true then, Harry Potter has come to Hogwarts."
I looked at my sister, we had heard of the rumors of course but didn't actually think that we'd be in the same year as him. We looked back at the blond boy talking to, who I could only assume was Harry Potter.
"This is Crabbe and Goyle" gesturing behind him "and I'm Malfoy. Draco Malfoy."
Ahh I thought I recognized his hair. I quickly turned when I heard a snicker come from a boy I could only assume was a relative of Fred and George. Malfoy apparently didn't appreciate that as he sneered back "think my names funny do you? Red hair, and a hand me down robe. You must be a Weasley."
Addressing Potter once more Malfoy put out his hand "You'll soon find out that some wizarding families are better than others. I can help you there."
Potter coolly replied "I think I can tell the wrong sort for myself thanks."

"Idiot, I doubt he even realized who he just insulted. Malfoy's going to hate Potter for embarrassing him in front of everybody."
I whispered to my sister. She replied back even quieter since the older lady had just returned
"Maybe but Malfoy was being a git about everything."
We quieted down as we walked into the Great Hall. I was astounded by the ceiling, I knew that it was bewitched to look like the night sky. I had read about it over the summer, but I almost rolled my eyes when I heard a girl proclaim that for all to hear behind me. Way to be a know it all. Although the room was enormous, all too soon we had reached the front where a stool with a tattered hat sitting on top was located. We were called up alphabetically and next thing I knew I heard it, "Isabelle Herondale."

I watched as my sister calmly walked up to the stool and sat down. After about 30 seconds the hat shouted out "GRYFFINDOR." I watched as she smiled my way and walked over to the Gryffindor table. Then came my name "Katherine Herondale."
I walked up to the stool calmly, I couldn't show any weakness, and sat down. The hat had only been on my head a couple of seconds before it shouted out "SLYTHERIN."

There was silence at that, my family isn't like the Malfoys or the Weasleys, but we're known around the pureblood community. Well known enough to know that there hadn't ever been a Slytherin in my family. I glanced over at my sister who looked at me with a smile and the 'well, we all knew this would happen' face. I smirked back and walked over to the table where I sat down next to a blonde first year girl. A few minutes later, food appeared on the table and we all set about getting to know each other. Around me there was Draco Malfoy, Vincent Crabbe, Gregory Goyle, Theodore Nott and Blaise Zabini for the first year guys. For the girls there was Pansy Parkinson, Tracey Davis, Millicent Bullstrode and Daphne Greengrass.

I was trying to figure out who to befriend when Pansy addressed me. "So Herondale, I thought I recognized that name. A bunch of blood traitors is what they are. You even have a sister in Gryffindor. Tell me, what's it like being a disgrace to your pureblood name?"
I looked at her gloating face, which just then, looked a bit pug like. With a nonchalance that I knew would become second nature I replied
"Well I wouldn't know, maybe you'd like to tell me?"
With a confused look on her face she stammered out a "what do you mean?"
With a smirk I replied "Well, purebloods are supposed to be good looking aren't they? I'm afraid they got you all wrong. Are you sure that your parents didn't have a pug instead?"
Pansy's face went bright red at my accusation and I turned away and decided that Daphne, who was unsuccessfully holding back a laugh, should be my friend.
"Hello Daphne right? I'm Katherine, but Kat for short." She smiled back at me, always a good sign.
"Hello! Yes it's Daphne but you can just call me Daph if you'd like." We continued on all throughout the feast. We talked about classes and what we were looking forward to, she was interested in classes which was a definite good sign. Then I mentioned that I love playing Quidditch and she mentioned that she loved Quidditch but was awful at playing. It wasn't until I remarked that Pansy needed to take Etiquette lessons, because how she was eating was downright disturbing, and Daphne replied saying "if my teacher was here, she would've told Pansy 'Well if you can't look or speak like a lady, the least you can do is eat like one. You are not an animal…" at this point I chimed in with the response that I knew by heart "act like it!" She looked at me and we dissolved into giggles.

"No, you had Madame Pinchfort too? I thought that I was the only one stuck with her awfulness."

Happy someone else had shared my pain I responded eagerly "Oh yes, I was either her favorite or her least depending on how many times I managed to insult her while never breaking a rule!"

"Oh I'm sure she loved that."

"I don't think she knew whether to praise or berate me for it! I hated her classes though. So boring. I mean a women is to be seen not heard. Who came up with this rubbish?!"

"Exactly! I mean, I want to learn magic here and be qualified to work if I want to!"

"I'm so glad that someone agrees!"

By this point we had reached the common room, the password was Ambition, and when we walked in I was in awe. The room was beautiful with green and silver accents and black furniture. There was an open window to the lake and a large fireplace warming the room. We all headed straight for our room and when we got there, with just one look, me and Daphne took the beds next to each other by the window in our room. I went straight to sleep, I wanted to be up early to talk to Iz and see how everything went for her. Exhausted I feel into a dreamless sleep.
