Summary: What if James had a twin sister?  But what if he was a little less than proud and eager to claim her?  Well, this is her story...

Background:  This is James and Jayna's seventh year at Hogwarts.  The story starts out on the first day of school on the Hogwarts Express

Warning:  This has nothing to do with my story, Her Other Life.  This chapter does contain one swear word.  It's the "d" word, so if you're offended, sorry!  I myself don't like to swear, but it's in my character's personality so I decided to put it in there.  That will most likely be the only swear word used in this story, so please don't let that stop you from reading this!!  Enjoy!!

Everything Changes

Chapter One:  Meet Jayna

Jayna giggled.  "Oh, Ryan!" she squealed while poking Ryan in his side.  Andrew, getting jealous of all the attention Ryan was getting, decided to "steal" a kiss from Jayna.  However, you can't steal a kiss from the willing.  And Jayna was definitely more than willing. 

 "Hey, anybody seen James Potter?" Sirius Black asked, while poking his head through the doorway into a compartment on the Hogwarts Express.  "Oh," he said, disappointed in what (or who) he saw in the compartment.  "Never mind." 

"Do you mind, Sirius?" Jayna asked snottily.  "I am not my brother's keeper, nor do I care where he is, who he's with, or what he's doing!  So why don't you do us all a favor and leave before we make you!"  Jayna spat out with disgust.  Her companions, Ryan, Andrew, Jonathan, and Alex all brought their wands out of hiding and fingered them while glaring at Sirius. 

"What?  You don't want to make this into an orgy with five different guys, Jayna?" Sirius asked her sarcastically.  "Is that how you plan to get on with your life after this year?  When you get out into the real world?  You're just going to sleep your way to the top?  Well, I guess that does fit your personality just perfectly, Jayna.  But when I become Minister of Magic, there's no way I'd even let you clean in the Portkey division!" Sirius told her and slammed the door. 

As he stalked down the hall, Sirius wondered how Jayna had changed so much from her first year to her seventh and final year at Hogwarts.  He silently marveled at how different Jayna and James were despite the fact they were twins.  He snorted and finally found his friends:  Lily Evans, Remus Lupin, Peter Pettigrew, and of course, James Potter.  "Hey guys, guess who's still the Hogwarts Hoe?"

"How dare he!" Jayna fumed loudly to her boys.  "I cannot believe his nerve!!  Like I would ever sleep with him or any of those Marooders!" 

"Um, Jayna," Andrew said nervously, "I think they call themselves the 'Marauders.'" 

Jayna exploded.  "I don't give a damn what they call themselves!!"  Jayna paused and thought to herself.  Hmmm.  What does he really hate?  Jayna struck inspiration.  I know exactly what I'm gonna do, she thought and laughed. 

After the Sorting and the feast, everyone went to their towers and after a while of talking about summer holidays they went to bed.  Jayna laid silently in her bed listening to her roommates', Victoria (Vicky) Hosbrock and Lily, breathing become even.  When she was finally convinced they were asleep, Jayna quietly got up, plucked something from her trunk, and left her room.  She padded softly down the hall to go into another room.  When she found the person she was looking for, snoring quietly, she grinned a nasty grin to herself.  After Jayna had completed her "mission," she left just as silently as she had entered and went back to her room to go to sleep. 

In the morning, Jayna was awakened by an angry yell quickly followed by gasps and laughter. 

To be continued...

What happened?  What did Jayna do and whom did she do it to?  Find out in the next chapter and guess what you think happened in your review!  (Hint hint!)  Also coming in later chapters:  why Jayna is the way she is.  But tell me what you think might have happened in the past six years at Hogwarts to make Jayna change so much, according to Sirius.  If you have any questions, please ask!  I know this is kind of confusing, but bear with me!  It will make more sense in coming chapters!!  Thanks for taking your time to keep reading this and please remember to review!!
