Authors Note: The majority of the changes that I made to this chapter involved keeping the changes I've made to previous chapters consistant, expanding on the skeleton the original chapter gave me, reigning in the unlimited and correcting myself. If you were with me watching as I go through this, it wouldn't be a pretty sight lol. As with previous chapters there were some places where I wondered what the heck my younger self was thinking- like the part where Lizzie seemed to know all about James Potter yet had only been there less then a day and had never met him. and Oh God, the retaliation prank and 'telepathic' moment. It was very inconsistent, and a pain to rework into something that was in any way... plausible. Let alone not cringe worthy. Worst thing is I know that going forward I'm going to have to rework more of this same issue- that and Lizzie getting too... friendly with people too soon I took out entire parts and added new text to fix it to be honest, and it's going to happen again. Pray for my soul Loves. I am still having fun.

To Those Who Flame as an Anon: This story will not be perfect- I have accepted this and so should you. I am working with an original that I did as a child, and I don't want to just scrap it and be done with it. To be honest, in order to stamp out the mary sue properties completely I would almost have to kill the original story line and just start something new. I've labeled it AU, I've put warnings galore up, and I talk about the changes that I'm making to the original as I rework it in my A.N.s. There are clear warnings everywhere you look that this isn't going to be a pretty polished, store ready book- so don't expect everything to line up with what you expect from your interpretations of the characters.

If you're going to degrade me for the sake of feeling superior... your review will be deleted. I don't do this for anything more then my pleasure. I take no commission ect, I make no profit other then seeing others enjoy what my mind comes up with. Every moment I give to writing I am taking from other things in life. I don't need to waste that time reading things that do more hurt then point out anything helpful that could be changed to make the story better.

Thank you for your time Silver AKA Toxic

A.U.: Lily is in Slytherin in this story and Lizzie may not act like you may think a female Harry would/should.

Now Onto the Story

Lizzie got up early the next morning, eager to see if her grandparents had responded to her letter yet. While she was preparing for the day, she got one of the expansion charmed bags out of it's compartment before putting all the text books and supplies that she would need for the day in it. She then added a couple extra books that she knew she wouldn't need for the classes that she had but wanted to have on hand for if she got bored and wanted to read something. The teen had no idea how hard the classes in this era would be, so it was possible that she would be ahead of her peers after all. That or behind, but she had to admit if that was the case then she wouldn't be sleeping much. There was no way that the teen wanted to be last in her class- even if Professor Snape wasn't here to see her grade she still intended on making his prediction come true. Lizzie would have it as a point of pride to hold onto, if nothing else.

When she was finished adding anything that she could think of, she had to admit that really glad that the bag also had a weightless charm built into it. If she had tried packing all of this in a bag without one, then there was no way in hell that she would be able to carry it. She got out her clothing for the day next before heading to the bathroom and getting ready for the day. It was only when she was heading out of the room that she remembered she would need a time-turner for her classes. Sighing, and wondering why she hadn't thought of it sooner, the teen went to the compartment of her trunk that had them. Looking at the pair that she had to choose from, Lizzie chose the one with the most features.

It never hurt to be prepared for any situation, and while she doubted that she would need to bring any one with her the resizing charm on the chain could prove useful if for nothing else then preventing a bigger problem. She had enough of random time travel after all. The teen carefully put it around her neck, before hiding the hourglass in between her breast. Lily stirred across the room up soon after Lizzie had finished, so she paused and waited for her to get ready. She didn't need to be this early- but she was eager to be down there in case any mail came early.

"Good Morning Lizzie, I hope that you slept well." The red head greeted before grabbing her own clothes and going into the bathroom to get ready. When she got out she started trying to stuff her own bag with all their text books. And it was clear pretty quickly that her attempt to fit everything just wouldn't work. Lizzie was chuckling quietly, remembering her own thoughts just a few moments ago as she got into her own trunk and dug around for an extra bag that was like hers. The time displaced teen grinned triumphantly before turning around.

"Lily, You're not going to get all of that into your bag without it tearing apart." she said "Here is a bag. It's weightless, and has a pretty heavy duty expansion charm on it. It also has a pocket that supplies about 50 feet parchment before the charm needs to be renewed, one that keeps your ink topped up for a week before it needs refreshed and one that keeps your quills sharp for as week at a time as well. My bag has many of those features as well." Lily looked at the bag impressed by the features that Lizzie had listed, before grabbing it. She easily got all her books in it, and a couple more that she added when it was clear that her 'sister' wasn't kidding. She had never heard of something like this before, and wondered if the other girl had gotten them custom made. They must have cost a pretty Galleon though.

"This is amazing Lizzie. Where did you get them?" she asked, when her interest couldn't be contained. The hat had considered her for Ravenclaw as well, but she had been determined to join Severus. And Severus had been sure that he was going to Slytherin because that was where his mother had been. It had been easier then Lily had thought it would be to get into the house that she wanted to- because while the hat made it's suggestions it also listened to what the person it was sorting wanted. If the desired house matched a quality of the student, then there was a good chance the hat would agree to the request. Of course Lily had no idea if this was general knowledge among Purebloods, so she had kept that discovery to herself. She didn't need to add know it all to her muggleborn stigma after all.

Lizzie blushed a little at the question, because she had no good answer for it. The Weasley twins had developed those bags for Potter in order to help him get away from the Dursley's if he ever had the need to. They would make it so he wouldn't have to risk using his wand and getting in trouble again for under age magic. Those two had stayed Potter's friend even when Ron and Hermione had started drifting away from him. But Lizzie couldn't just tell that to Lily, so she compromised- blending fiction with a modified truth to fit her needs. The Frostpine family was well off, they could have possibly commissioned a private company to build a proto type line of book bags for their daughter. and since it was a commissioned prototype it wouldn't be available to the public without permission. She smiled to herself, mentally giving herself a pat of the back as she decided on what she would say.

"They are prototypes that haven't been offered to the general public since they were a custom request, but don't worry the work perfectly- I didn't get them until they had been put through testing to make sure they wouldn't malfunction and explode. I don't think they will be on sale for other's to by for a long time yet though." Lizzie replied simply. "Now I want to get to breakfast soon. I kind of forgot to actually eat dinner last night, plus mum and dad could have written back. I'm a bit nervous to see if I'm going to get grounded for my behavior or not." She added after her stomach gave a growl. Lily laughed at her admission before nodding. It only took a few minutes to make sure that they had everything that they would need before they left for the great hall. The new bags hanging over their shoulders while the girls themselves were chuckling silently all the way as they talked and got to know each other. On the way to the great hall their conversation turned to boys naturally. Lizzie smiled slyly at her 'twin' sister- she didn't know where Lily stood in relation to James Potter at this point in time and this was a great chance to find out.

"So, Lily We've talked about a few things, but not about boys yet. Who do you think is cute in the school?" She asked knowing that she was being blunt and was obviously fishing for some information. Since this wasn't something that Lizzie did often, she hoped that she wasn't coming on to strong. She didn't exactly know how girls went around talking about this kind of stuff after all. Lily blushed at the question- looking at a suite of armor that they were passing, before glancing at Lizzie.

"Umm, that is kind of personal. And very embarrassing considering my answer. You'll meet him soon enough though I suppose, and he may be an arrogant toe rag, but he does seem to be developing some redeeming qualities. I can only hope that you don't end up judging me when he ends up doing something foolish." she murmured quietly, knowing that most Slytherins would not like her choice in crushes. But her sister had been here less then a full day, she hadn't had the chance to form the opinions that the other had so she would be safe to talk to about this. At least the safest of all the Slytherin girls that she could choose to confide in. Lizzie stopped walking and smiled softly at Lily trying to encourage her to talk.

"What makes you think I would judge you? The only person I have any connection to here is you. I'm only asking because I want to know you better, we have so much to catch up on after all." she asked kind of intrigued by the other girl's reluctance to answer her question. Other then getting to know her new sister she was trying to get a feel for any crushes- and she had to admit that she wanted the boy her sister was hesitant to name to be was James Potter her future mother was so infatuated with, and not Severus Snape considering her own thoughts on the other teen/future professor. She might not be supposed to know him here, but she now knew that she had had feelings for him. The hat and his teasing had helped her puzzle that out yesterday. As Potter Lizzie hadn't admitted that there were any feelings beyond friendship, but looking back she now understood why Potter had allowed himself to open up. She smiled to herself mentally, it was really getting annoying thinking of herself in both male and female tenses, well that and confusing. She returned her attention to her 'sister' who was now blushing.

"I don't know, Most Slytherins would look down on me if they knew who I like because he's a Gryffindor. Though they normally look down on me because of who raised me, so there isn't much of a change there" She said with no little amount of exasperation, "But I think I can trust you, I don't know why after all I have only known you less than a day. But I feel completely at ease with you. The boy that I think is cute is none other than the supposed bane of my existence, James Fleamont Potter. It's a recent change, most of the time he's a pain in the arse so sometimes I wonder what I'm thinking even considering him in that way." She added looking away as she spoke. Lizzie hummed, she knew that she couldn't act like she knew him, but she could give her sister some encouragement.

"Potter is a pureblood name, one that may grant him a pass for his House even. I know that the Black family has had females marry into the Potter one and they are primarily Slytherin sorted. Once your heritage is known, the other Slytherin's may not be as opposed to your crush as you think. Though I am sure that you will find yourself approached by many people too. The Frostpine family doesn't marry our cousins, and we haven't intermingled with every family in England. We're essentially fresh pureblood to strengthen their lines. Watch how the males treat me if you want proof. So why is Potter an arrogant toe rag most of the time?" She replied, before probing a bit more- if she let Lily tell her about Potter then she could use this talk as a reason why she knew things.

Lily let a relived sigh out at the easy acceptance and the explanation that he sister had given her, Lizzie didn't think less of her, while she knew intellectually that the other girl had no reason to make judgments like the rest of the school, she was just plain terrified of saying or doing the wrong thing and losing the sister she had gained the night before. The teen was desperate for everything that she had been told to be true- for her to have a sister that could share the magical world with her- one that actually liked her. Petunia had been growing colder and meaner as the years passed and it hurt. Lily had looked up to her older sister right up until the letter came and the blonde had thrown her away for a talent that she was born with. She had lost that hero because of Magic, but magic may have given her another.

"Potter is an arrogant toe rag because of how he acts. Don't get me wrong- he can be funny, some of his jokes that he plays with his friends aren't bad. But he also has a nasty habit of targeting certain people. Like Severus. I got into Slytherin because I met Sev before I got my letter. He explained the wizarding world to me, told me why things happened when I got emotional and he became like a brother to me. He was so convinced that he was going to be in Slytherin, and afraid about what that would have meant for our friendship. I didn't understand why he was so sure that being in different houses would eventually ruin our friendship, but once I got here I understood. And even though Slytherin has been nothing but thinly hid prejudice about my blood I will never regret making the choice to request a place there." She explained softly.

Lizzie stared at her sister for a moment, before a bright smile broke out on her face. Apparently Potter wasn't the only on in the family to get out of a house by asking to be put in another. And Potter had shared that talent with his mother and had never known it, it was a priceless piece of information to the teen because everyone always spoke James Potter. Lily Evans had remained a mystery to her child. The conversation died down after that as the girls started walking again. Lizzie hadn't been there long enough to decide who was cute or not, so there was nothing to share there. As they reached the Great Hall Lily made a gesture towards the Gryffindor table and the group of boys that were huddled together and sneaking glances toward the girls' house table. Something was up.

"We really should be careful this morning. Those boys look like they are up to something. I love a good prank or two, but I think I'd rather avoid being hit by one on my first day here." Lizzie warned with a barely there hum. Lily narrowed her eyes at the four boys before nodding as they made their way to sit down. After they had settled Lizzie looked over the mentioned group and winked just to mess with them, though she didn't think any of the ones who had been looking over had caught it. "If this is good, I might not mind helping them with a prank every now and then." She whispered to her sister after the boys looked away form the table. Lily snickered, before greeting Severus with a hello as he sat close to them.

"I wouldn't eat anything until after the others do and we see what they have done." Lily advised her friend before nodding her head towards the Marauders. "Lizzie and I saw the Marauders acting suspiciously, so we think they may be up to something." She added as explaination. Lizzie grinned in approval, knowing that the warning would be better received coming from someone that the future potions master knew. At this point in time all Lizzie was in Severus Snape's mind was the new girl who had stood up for Lily. And may be psychotic if her attack on Narcissa was anything to go by. The time displaced teen resisted the urge to laugh at that though as a noise of agreement brought her back to the here and now.

"I had noticed their looks as well and would have to agree Lily. They are going to cause a scene today, and I would rather not be part of it if I could help it." The male teen agreed, with a soft smile to his friend. Lizzie was struck by that smile- she didn't know if she had ever seen his future self make that expression and mean it. It made him look more attractive to the teen though. Severus nodded in Lizzie's direction after a moment "We haven't been introduced yet, but I am Severus Snape. I consider Lily one of my dearest friends so I must thank you for standing up for her last night. You have made Lucius start to reconsider his stance on her, and his own betrothal in one night. His wife to be is the unfortunate chit that got a taste of your casting skills." He introduced himself, and having the other teen's attention focused on her was not helping the niggling crush that was loose in her chest at all. She pushed back the feelings that he was invoking and gave a small laugh instead- focusing on his words.

"I think you will find that I have reasons for not tolerating that kind of behavior towards Lily Severus." She replied, keeping her voice from rising in pitch or making any embarrassing and unwanted squeaks. Was this normal for girls with a crush? Once again the teen cursed life as Potter. Because for some crazy reason she didn't really have much to compare to. As Potter she had one or two attractions, but the one with Cho had crashed and burned pretty quickly, and Potter had never squeaked around Cedric. Ginny... the youngest Weasley had acted oddly around Potter. So maybe that was her confirmation. Of course thinking of Ginny turned Lizzie's stomach a bit because that pairing would have never happened when Potter was in his right mind. One Black eyebrow raised at her statement.

"Indeed. I will look forward to finding out what that reason is. I have a feeling that it will cause as much commotion as you did last night." He murmured, loading his plate with food as to not draw attention to the fact that they were not eating yet. Both girls followed suite and then the wait to see what would happen was on. Lily nudged her sister's leg during the wait and when she had the girls attention she gave her a secretive look before raising an eyebrow at the boy next to them. Lizzie flushed, not believing that she had made any sort of visible reactions that her sister could have picked up on. She must have, because a sly grin passed over the other Slytherin's face.

"I saw that." She whispered playfully, leaning against the blushing girl's shoulder. "And I don't think it wasn't just on one side either. He doesn't normally talk like that to people." She added as they watched the group of boys closely. The four still sneaking looks over to the table every so often- waiting for their pranks to take hold. They were being painfully obvious about it- or they were in Lizzie's point of view. Lizzie grinned as she though that, wondering what was going to happen.

Suddenly a seventh year took a bite out of her food and her hair promptly turned red and gold. Unfortunately the change wasn't noticed quickly enough and soon the majority of the table had undergone some sort of change. Severus, Lily and Lizzie were one of the 'lucky' ones who hadn't taken a bite of the food. But all around them Slytherins now had Golden and Red hair, and the changes didn't stop there. Each person effected also now had golden and crimson robes that either said 'I love Professor McGonagall' or 'I love Professor Dumbledore' depending on the gender of the student afflicted. It had been a prank that was more then slightly mean towards it's intended targets, Lizzie noted to herself. The Slytherin house was no friend of either teacher, and partially because of their own actions and behavior towards the snakes of Hogwarts. To have to wear their colors, and have that written on their person would be an ultimate embarrassment.

The unaffected Slytherins watched their housemates in a mixture of sick amusement and horror, while thanking merlin that they hadn't taken a bite of food yet. As a whole the house's had disappeared in fact Even the trio that had abstained from eating because they had a hint that something was going to happen. No one wanted to be one of the people who were now walking Gryffindor mascots. The once affected soon discovered that they would have to deal with their new looks for the rest of the day-maybe even longer since the boys hadn't bother on brewing any counter potions to their prank. There would be more then a couple unhappy student today- some of them may even try to skip class to avoid being seen but the four teens didn't seem to realize that quite yet.

The Frostpine sisters looked over to the Gryffindor table once more and saw the Marauders were enjoying the reactions to their prank. The boys were almost rolling on the ground while laughing, or rather James Potter and Sirius Black were. Peter Pettigrew and Remus Lupin were watching the reactions closely. Lizzie's eyes narrowed on one in particular. Peter looked afraid of the reactions that he was seeing- and he had a sort of nervous energy about him that didn't fit with just being scared about retaliation. That made her frown as her mind started to race a little. Was Wormtail already a traitor? Did he already have allegiance to the man who would kill his friend and Lizzie's new sister? Could she keep her mouth shut and stay her hand when it came to the bastard when she knew that she could save her parents with a simple Killing Curse?

She gave herself a mental slap as her thoughts started scattering to the wind with the what ifs that were now very real to her. Now wasn't the time to plan- that could happen later when she had time to isolate herself and plan. The teen refocused her concentration on the group of boys and smirked. While she could let them get away with whatever punishment the teachers had planned, she had a feeling that until they got a taste of their own medicine they would never grow up. And things would be so much simpler without Potter and his friends being jackasses. She waved her wand and cast some charms on their unprotected food that would mimic the results of their prank and then sat back waiting for the fireworks to begin.

Several professors had made their way over to the pranksters by now and the boys were being reprimanded for their actions. Though the punishment probably wouldn't do much to deter them from doing anything else based on the grins the boys were still sharing. Fifty points were taken from their house and they got a month detentions in between the four. It was a slap on the wrist at most, and Lizzie could clearly see the darker side of their fun. In not really punishing the teens for their actions the adults who were in charge of this school were sending every student a message. Those four could do what they wanted, and they would only pay for their actions with a handful of points and some of their free time. The so called fun loving teens were the ones really in charge of this place, and whoever caught their eye was out of luck.

The pranksters were still snickering in amusement, the punishment having not phasing them in the slightest, when they took the first bite of food. The four boy's hair turned silver and green, as did their robes in a smooth transition. Since there were no corresponding teachers that the Gryffindor boys would be offended to declare their love for, the statement they got instead was a love for Slytherin's in general. Though Lizzie had cheated a little when it came to her future father. James robe said 'I love a Slytherin' instead of the blanket 'I Love Slytherins' that the others received. Their look was finished off when they each sprouted scales on their arms and a little on their face, their eyes shifted to a more snake like look and their tongues became forked.

As an afterthought Lizzie decided to send a note to Remus with a quick wave of her wand under the table- if they didn't know why this was happening then they would assume that another group had come to play and this would be little more then the opening move of a prank war. While that was correct in a way, or at least she hoped that she could encourage it to become something along those lines, it wasn't just that. The teen wanted them to learn something from this, and maybe open a way for them to become friendlier since the language of pranks was what they understood best. So in her note, which said 'Compliment of the Raiders, a Tit for Tat production.', she implied that this was payback. Lizzie planned on getting her new sister and maybe even Severus involved in any future pranks, but that would be something that she would have to wait and see on.

As the rest of the Gryffindor's eyed their food warily, wondering if it was as tainted as the Slytherin houses' meal had been, the hall came to a standstill. The time displaced teen felt a moment of guilt for making them feel that way, but she pushed it aside. As Potter she knew how the house could come together when something was happening that they didn't approve of. Lizzie leaned over to her sister and let her know what she had done, in the vaguest terms possible before doing the same with the Slytherin boy next to them. She would explain more later of course, because there was no way to hash this out in the hall after all. If both Lily and Severus wanted to join her in this, then they would also have to plan their next move as well.

Sirius Black was angered by the retaliation at first- you could tell that from the shouts and hisses he was letting fill the Great Hall as the teacher who had previously scolded the group stood looking confused by what had just happened. The universal constant was that the Marauders would pull a prank, get a slap on the wrist and then eventually the cycle would repeat. Seeing them pranked back was alarming because the school couldn't handle two sets of pranksters. Not after what the one set had already conditioned them to. Remus found the letter that had appeared in his pocket after a few moments, as he was patting his pockets and looking for his own wand. He had been going to try a finite, but the parchment shocked him about as much as his current state of dress. He gathered his wits and showed the letter to the other boys a few seconds later. Sirius' expression turned more curious than upset in a matter of seconds.

"Oi! Who are the Raidersssss then? Even though it ssssuuckss that we are the butt of the joke it was a nice prank back. Jamssssiesss sentence is brilliant, consssidering hisss crussssh " He asked in a loud, sweet voice. It had more then a hint of annoyance hidden under the charm, and Lizzie had no doubt that her future godfather would strike back at whoever dared show themselves. He was a Black after all, and while he may be a Gryffindor his family had a well deserved reputation. The teen's letter s's were drawn out due to his forked tongue, making the words with them suspiciously close to Parseltounge to Lizzie's ears. The two girls shared a look that clearly said not to get up with each other. Sirius sighed knowing that the mystery group wouldn't show themselves yet, they were far to smart for that if they had managed to get one up on the Marauders. Just then Hedwig came wit a small bag and letter clutched in her talons. People watched in amazement as the phoenix swooped and landed peacefully in front of a Slytherin, and Lizzie resisted a snicker. Let the idiots chew on the fact that a slimy Slytherin had a phoenix delivering her mail.

"Thanks Girl, Why don't you go rest? I know that you probably had a long night." She said taking the items from her and giving her some bacon in a smooth and practiced motion. She wasn't about to get pecked because she tried that without some sort of offering to the white creature. The time displaced girl gave a look to Lily and saw that the other girl had started a conversation with another Slytherin. A look to Severus showed that he was talking to Lucius as the Hall was calming down. The fact that no one knew anything about this new group and the Phoenix had broken the spell that had fallen with her prank of the boys and life was continuing on. Teachers were trying to reverse the prankster's new outfits and after a couple nibbles of food at various tables and the Slytherin meals being replaced by the house elves people were now eating. The teen smiled to herself and opened the letter eager to see what her grand parents had written.

Dear Elisabeth,

Thank you for writing to us to let us know where and who your mother is, no matter how you got here to do it. You have no idea just what you have done for us child, because we were losing hope that she would ever be found. Our last hold out- that she would be found via an inheritance test after she started school was looking bleak. The odds were not in our favor, and continued to fall each year that she didn't try to find out about her past- but as a muggleborn she would not have thought to do so. If we understand your previous letter then you are our granddaughter. While it is odd to know that we will get to meet you before your time on earth is supposed to begin we welcome you.

We sent your lovely phoenix to Headmaster Dumbledore last night, just as soon as we read your letter in order to set up permission for us to stay up at the school itself for a time. We want to get to know your mother and you, and while school is ongoing this is the only way we can without pulling you both out and disrupting your schooling. It seems that Albus has had quite a hard time finding a Defense Against the Dark Arts teacher- his current one handed in his resignation at dinner last night. Or so he told us as he presented a 'Solution' for our problem.

Because of this your Grandfather and I will be jointly sharing the post for the year, since we have the qualifications to do so. If that wasn't true, we would have found another way- I promise you that. We look forward to teaching you both, as it is an experience that we never hoped to have before. We will already be at the school when you read this, so I daresay that you may even see us soon. Your phoenix will have two shrunken four compartment trunks inside the bag. These trunks contain everything a Frostpine girl would need, or at least your grandmother assures me so. She also says that once we meet officially she will go through the contents with each of you.

We will see you soon- that I promise you.

P.S.- We have decided to reveal Lily's parentage to the school at dinner tonight so we may see how people interact with her without that being known. Officially you are now her twin sister legally- your grandfather, or rather father took care of creating your history while we were working out how to stay in the school. Even if Lily hadn't made the connection of you being her sister last night this would have still been out choice in action with you being the same age as her. We're looking forward to meeting you too.

Love,

Your Father and Mother

Lizzie smiled at the letter and brought the two trunks out before turning to her newly confirmed twin sister. The teen handed the other girl her shrunken trunk, and explained to her what it was and who it was from. Lily stared at it for a moment, seeming to be in shock before a grin spread over her face and she tucked her new treasure into her bag. While she couldn't wait to see what had been sent to her, she knew that she would. There wasn't much time after breakfast, so unless she skipped class to look into it she would have to. But the trunk itself felt like love, and the fact that the people who had been her family before she was stolen and adopted were here- had taken a post to be close- meant everything. They still care for her to drop whatever was going on in their lives and come to get to know her. It was rather awe inspiring to be honest.

Breakfast went by pretty quickly after the pranks and letter, and soon everyone was heading to class. The two sister's stuck together as they left the hall, once again falling into soft talks that were peppered with laughter. Behind them one Severus Snape watched Lizzie with interest flaring in his eyes. She was something new for the teen- within 24 hours she had stood up to Slytherin House and the Marauders. And then there was her sudden closeness to Severus' best friend. He could tell that the dark haired girl meant no harm in her interactions with Lily. If nothing else he knew that this would be an interesting year. Change was in the air.
