I was going to just post a teaser, but I've already got half the prologue done so I figured why not just start at the beginning? Please let me know what you think! I'm still in the rough draft stages of this, and I'm not sure if/when I'll finish it without motivation.

I never intended to write this fic, but I just couldn't resist. I'm fully writing my own vampire lore for this (because I've never seen Vampire Diaries, only read fics lol)

I do not own Teen Wolf, or any of the other characters in this story. I only own/created Nat, her characteristics, and anything that happens directly because of her.

Nat hated this part - the initial intrusion.

It was a calculated practice by now, but this was by far her most ambitious attempt yet.

She had began to feel tired recently, tired of the constant running. Surely she could settle down for a while, and this time would be different. The magically infested town of Beacon Hills seemed like the perfect fit for a long stay. Her kind was known to be solitary creatures - at least when it came to other mythical beasts - so she should be relatively safe from detection here.

A quiet life, where she could spend a the better part of the next six or so years...

If she was lucky, and extraordinarily careful.

The first step was easy: Locate the ideal host. A de-facto leader of the social arena she was entering would be perfect to reaffirm her claim to humanity if anyone became skeptical (they always did eventually, it was inevitable). If she planned to stay for a few years, it was essential to have someone who could keep any speculation at bay by attesting to seeing her grow up. Choosing the person with the best social standing was the best option, because people rarely wanted to question them anyway.

It only took her one afternoon of discrete spying from her 'borrowed' vehicle, to pin point the perfect candidate. This auburn haired teenager walked with her head held high, catching the gaze of almost every person in the area. She was flanked on either side by clearly replaceable girls - it was almost cliche how closely she resembled a typical Queen Bee. Nat was too far away to get a clear taste of her scent, but judging by the way she groped that muscular jock, this girl was no innocent.

It was almost too easy to follow the Queen Bee home. Nat made the excuse of needing to use their phone, because her own had died, and the father was all too eager for the unknown young lady to come inside. Once there, she found her target and from that point forward she was Natalie McCarthy - the childhood best friend who this Lydia Martin had been keeping in touch online for over a decade. Then, with a lingering glance and few choice words, Lydia's parents opened their home to the orphan girl they loved like a second daughter. Their families had met on holidays, and the two girls instantly connected, but Natalie's had just passed in a tragic fire so she had no documentation. When they heard the news of their passing, the Martin's had insisted she come and live with them because they knew she had no other living relatives in America.

They helped her to arrange all the paperwork the next day, and after convincing the woman behind the counter of a few things as well, Natalie McCarthy officially existed.

It was almost too easy.

The new girl was beautiful, stunning, perfect.

Rumor had it, she was Lydia's best friend who's parents had passed away in a tragic fire - kind of like the Hales a few years ago. Rather than letting her enter the foster system the Martin's had opened their home to her.

It was kind of weird that he had never heard Lydia talk about her before, but Stiles decided not to dwell on it. It's not like he knew every single detail about Lydia's life.

Well... Not anymore.

This new girl, Natalie McCarthy, had immediately captured all of his attention from the moment he first laid eyes on her. As she walked through the halls beside Lydia Martin, he felt his heart stop.

She was smiling softly as Lydia Martin pointed out all the different people, entirely skimming over Stiles and Scott - which was fair enough because Stiles had skipped over her too. But... Natalie McCarthy... she didn't skip over them. She looked him directly in the eyes, behind her thin silver glasses, and gave him a warm smile that made his heart to front flips towards her. Stiles actually had to grab a hold of the table so he didn't do something stupid like immediately run up and introduce himself.

He had enough wits about him to notice he wasn't the only one reacting in such a way, although most of their peers weren't quite as composed as he was. A small crowd had began to form around the pair.

He was by no means the only person she had smiled at, but it didn't matter. Stiles had just seen the girl he was going to marry one day, and he tells his best friend as much.

Scott said he had a better chance continuing to pine over Lydia Martin.

But what did Scott know? Stiles couldn't go back to pining after his childhood crush - not anymore. No. Seeing Natalie McCarthy smile had changed him irrevocably.

His crush on Lydia Martin was completely overshadowed by this gorgeous girl; who smiled at everyone and rarely ever left her best friend's side.

He did his best to capture her attention, like she had his. Any attempts of starting conversations when they even remotely crossed paths in the hall fell flat, because Lydia Martin managed to expertly steer her away every time. To make matters worse, she never really seemed to sit in the cafeteria for lunch - having apparently gotten special permission to use the art room - so there went the possibility of chatting to her in the lunch line.

Then he found the perfect opportunity to get to know her.

No one had sat next to her in Chemistry.

It seemed like this unspoken rule - that no one was worthy to be beside her.

Maybe it was because there were so many people who wanted to be there, so they were too busy squabbling over who should have it, which left the seat was just wide open.

Well, not for long.

The teacher was entering the classroom, in just a few moments the seating plan and chemistry partners would be set by default.

Stiles doesn't think about what he's doing - he just acts.

Gathering all his things into a messy grip and fumbling with his bag, he catapults himself beside her and slams his work down. Breathing heavy, he tries to look totally casual as the teacher turns around to begin the lesson.

Natalie McCarthy gives him a peculiar look out of the corner of her eye, thoughtful and calculating. It's a look he hasn't seen from her before, and excitement sparks in him to already be discovering more about her.

He honestly doesn't have the courage to say anything, far too nervous; he just smiles awkwardly.

And something incredible happens.

She smiles back.

Natalie McCarthy looks to him with clear shock on her beautiful face for just a moment, her mouth forming into a perfectly adorable 'o' shape, before she smiles. He almost melts in his seat, a hot blush on his face. She was so beautiful.

But, determined not to be a terrible desk mate, he does his best to pay attention. He take notes, stays quiet, and tries not tap too obnoxiously with his pen, as his nerves slowly eat away inside of him.

It takes him weeks to actually work up the courage to talk to her in class, and when he does it's some horribly basic question that he kicks himself for even asking. Yet - the unbelievable thing was - she actually explains it to him! She doesn't patronise him at all, and perfectly brakes down the answer as though he isn't an idiot!

She didn't just brush him aside - it was unbelievable.

Life was good.

He, Stiles, was actually on good terms with the hottest chick at their school. He couldn't believe it, he was flying high.

But, perhaps, he flew too close to the sun.

Because just when life was getting great, unbelievably great, he saw her - the real Natalie McCarthy.

She had been mildly intrigued by him from the start.

As Lydia showed her around the school and pointed out all the students she needed to know, Nat paid close attention to the ones she left out.

Those would be her most viable option for a fresh supply.

There was something about that one boy, who looked stunned to see her, that sparked recognition deep inside of her... at first she thought he could be one of her kind, but no - his cheeks were flushed with a slight blush as he gawked at her... So, she easily dismissed the feeling. In a life as long as hers, it was inevitable to see some vaguely familiar faces.

In all honesty, it wasn't until he sat next to her in class that she really took note of him again.

She was surprised that anyone would have the courage to take that seat, let alone someone of his social standing. Nat had convinced all the corrupted (which covered essentially all the popular kids) to leave the seats beside her vacant, excluding Lydia of course. She had naively assumed that because of this, the rest of the students would follow suit.

Yet, this tantalising, innocent boy had surprised her. He had thrown himself into the open seat with reckless abandon, then had tried to tried so casual about it all despite the pounding of his heart.

It was almost endearing.

She quickly and subtly inspected him under her critical gaze, wondering exactly how much of a threat this human could be. If he got too close, he may feel the distinctly different nature of her skin - he may realise that she is not quite like the rest of them.

And then something peculiar happened - he smiled at her.

But, it wasn't just any smile. She was far too used to the fake smiles these humans gave to made each other more likeable. No, this was an awkward smile, a pleased smile, a hopeful smile...

It was a nice smile.

And she felt something shift inside of her, like a memory trying to break free - or perhaps it was just an urging to actually respond because she had been staring at him for far too long.

So Nat gave him one of her best, practiced, smiles in response - and he was the one left staring. His jaw went slack, and his whiskey eyes were wide with surprise for a few moments. Then, he shook himself out of it and diligently paid attention to the teacher's lecture.

From then on they were lab partners.

And the idea of finding someone to use as a fresh supply was, strangely, forgotten. She was too intrigued by this strange boy to bother with any of the other students.

His quirky way of being amused her. He was clearly trying so hard not to disturb her; it was almost enough to make her feel something. And so clumsy, that boy could trip over thin air - she saw every stumble he made, every pen he dropped, every page he accidentally ripped from erasing an imperfect chart too hard. As time wore on, his small huffs and eye rolls at their teacher evolved into mumbled sarcastic remarks under his breath; it was clearly an unconscious habit as he had yet to actually introduce himself.

She could have easily uncovered the boys full name - their teacher had already referred to him as 'Stilinski' - but she wanted him to initiate a proper introduction between them. It was pure luck that Lydia was not in that class with them, otherwise she would have no doubt spoiled the surprise.

Almost at the end of her perfectly composed patience, he finally initiates a conversation by asking her a basic question their teacher had literally just explained moments ago. She notices the way he freezes and winces, clenching his fist as if preemptively expecting her to dismiss his intelligence; and him by proxy.

Once again, this strange boy stirs something inside of her, something she had not felt for far too long. She finds herself gently breaking down the question in the most thorough way she could to ensure he understood every aspect, to reassure him that she was happy to support him with the coursework.

The way he looked at her, like he cannot believe she is real, would have made her blush... if she was physically able.

Stiles, he said his name was, Stiles Stilinski.

How fitting - a strange name for a strange boy.

After staying too late at Scott's and needing his dad to come collect him (he could not wait to get his own car next year), Stiles caught sight of something in the woods.

Something that would change his life forever - again.

He knew what he saw, no matter what anyone tried to convince him.

Stiles had seen Natalie McCarthy.

Blood was smeared across her face and dripping down her jogging clothes, like someone had seriously messed up a wet shirt contest. At first he was worried she was injured, but then he noticed the older woman slumped at her feet, covered in more blood and looking far worse of than Natalie McCarthy. It was like a scene from a horror movie. Then, an absolutely and completely crazy thought ran through his head.

Vampire.

As if she had heard him say it - although he was pretty sure the word had not passed his lips, because his dad was still driving the cruiser as though everything was perfectly fine (which it was not, this was most certainly not fine) - her head snapped up and they made direct eye contact. He sucked in a breath and reeled back in shock as he met her narrow gaze of pure freaking black!

The patrol car whizzed past at that moment, and he turned in his seat to look back at her but she, and the body, had both vanished.

Any doubt he had in his insane theory was immediately erased.

Any trust he had in his sanity was gone too, because there was not a doubt in his mind. This new girl - the crazy hot, easily amused and sugary sweet Natalie McCarthy... was definitely, definitely a vampire.

After that the intimate dreams he had about her are replaced with intense blood pumping nightmares where he had to fight for his life... mostly.

Honestly, he preferred the nightmares.

At least those made sense.

Blood bags could only satiate her for so long.

Nat assumed it was comparable to living off of smoothies without solid food; eventually one began to just crave the feeling of that solid heart beat. And Lydia's... situation this week was not helping.

She had always planned on finding someone easy to convince, and keep them as a walking supply of sustenance. But then she had met her lab partner and... well, it had just slipped her mind... somehow...

So, she compromised. She went into the woods in search of a poor creature who could satisfy her craving; a nice big deer would be ideal.

It was just unfortunate that a poor woman happened to stumble into where Nat had been hunting - literally. She had scraped her knee when she fell down, and the smell was vivid, overriding everything around the.

Nat had been in so deep in stalking for prey that the scent of fresh blood had her leaping before she could even grasp the situation.

When she finally came to her senses the poor woman was dead and they were both covered in blood.

She was ashamed and horrified. Another innocent life taken to quench her never ending thirst, something she had promised herself would never happen again.

Just what would this slip up cost?

Perhaps it would be better if she just ended it now. Truthfully, she didn't quite know how to, but she had a fairly good theory on a method to incapacitate herself for the foreseeable future - which was the best she could help for.

Lydia might miss her at first, but it wouldn't hit her the same way emotionally. They were still essentially strangers after all.

And Stiles... well, he didn't truly know her. Perhaps that was for the best. She should remove herself from the equation before she did something that ruined his life forever.

The idea seemed more alluring, as she stared down at the corpse of the poor woman. Just moments ago she had her whole life ahead of her. Nat was so wracked with guilt, so absorbed in her fantasy of removing herself from this nightmarish consciousness, that she was entirely unaware of her surroundings.

She didn't notice the car approach, until the sound of a familiar whisper broke her from her trance.

"Vampire."

She looked up just in time to lock eyes with the shocked face of the worst possible person to see her like this.

Stiles Stilinski.

And, just to make matters worse (because clearly life hated her), he was in the front seat of a patrol car. His father's, if her brief glimpse of him was anything to go by - and it was, her vision was flawless.

Funny, he never mentioned his dad was the town sheriff.

Her survival instinct kicked in automatically. Grabbing the corpse she flashed away in an instant.

A woman matching the description he relayed to his dad was filed as missing the next day, but he still refused to believe Stiles' story.

Hell, he could barely believe his story!

But, when he sees... her... at school on that next Monday he knows it was real.

There's a look in her eye, not too dissimilar to the one she had the first time he sat next to her in Chemistry. She smiles the same way - actually the exact same way, like she had rehearsed it - but her eyes are not friendly. They remain cold and calculating.

He wonders if they had ever actually been friendly; was he so distracted by her beauty that he hadn't really seen? Had he just not notice how lifeless she was before?

Well, there's a lot of things he's noticing now, like how she never seems to get hit by anything. She manoeuvres gracefully between the students in the crowded halls without so much as a shoulder bump. It doesn't even seem entirely intentional, she's not paying them any real mind.

He decides to put his most recent revelation to the test, and what better time than lacrosse practice?

She had come with Lydia Martin, but clearly was uninterested in watching the game. Instead, she had her head in a book and appeared intensely focused on it.

Perfect.

Stiles lines up the shot perfectly... then 'accidentally' pegs it directly at the unsuspecting girl.

He's relegated to the bench for the rest of the season, potentially for the rest of his life, but it's worth it.

Because while the coach was screaming at him, Stiles was still watching her. He never took his eyes off her, and he had seen - or rather not seen - the movement. It's like the ball just passed right through her. He could have sworn he saw her whole body flicker, like a patchy old film reel.

Then she looked around with confusion before noticing him, and sending a deadly glare that makes him swallow nervously.

She knew what he had done.

And he knew that she knew that he now knew what she was.

Which was definitely horrifying.

...but, also kind of... exhilarating?

In, like, a really weird and confusing way.

Stupid, stupid, stupid!

If she had been paying any attention this wouldn't have happened! She should have seen it coming and managed to avoid the situation entirely.

But she, well, she had been distracted.

He had been muttering something under his breath, too low for her to quite understand. The trade up of perfect vision was a lackluster hearing ability. So she was attempting to listen inconspicuously while pretending to read.

Out of habit alone, she had already moved out of the way of the projectile and back before fully realising what was happening. When all the pieces clicked together it was too late, she had revealed herself.

It was the final nail in her coffin.

Now he knew for certain, because no human could have dodged like she just had.

She saw it in his eyes.

Why couldn't he have just left her alone?

The smartest decision for her would be to leave and not look back. But, she had established herself here so well. It was the perfect place to hide, because it was the least expected.

It was just her luck that now, after all these months, someone had found her out. And not just anyone! The only living family member of the town's elected sheriff.

Yes, she had looked into him - 'Stiles'.

Making him forget was impossible - she wouldn't convince an innocent. He had probably already told his father anyway, and that friend of his too. Perhaps she could just kill them all? Ah yes, that would be the perfect way to assuage her growing guilt!

No, that was not an option she could never entertain.

Besides, she couldn't kill them without drawing attention - she would need to immediately leave town and never return.

Maybe that was for the best, that she leave town and never look back. Make up a reason about a long lost relative who had filed for custody.

But then he would win and she would loose - and she couldn't allow that.

So what if he had uncovered her secret? No one would ever believe his story. Humans had long since stopped believing on her kind, anyone he confided in would tell him that he had been seeing things - no one would believe one silly teenager.

After that it's like a fog has lifted and it's all so obvious he wonders how the hell no one else has connected the dots.

There is something seriously wrong with Natalie McCarthy.

He just had to prove it.

"Firstly: She never seems to eat.
She spends lunch period in the art room, almost every. Single. Day. The few times Lydia manages to drag her out she just pushes the food around on her plate without actually having any.

"Secondly: Everyone loves her. Students, teachers, parents - Even Mister Harris!
Mandatory activities just aren't madatory for her. They say it's because she already did it at her previous school, but come on! That excuse has never worked for anyone in the past!

"Thirdly: She's super smart.
Like, she might be smarter than Lydia Martin. Have you noticed how she always ranks just below her, it's uncanny. It's like she's trying to fly under the radar. Sure, she might just say she doesn't want to outshine her best friend, but there is definitely more to the story there!

"And finally: Most damming of all, she never gets hit by anything.
Have you ever seen her get an injury? Have you ever seen her even brush shoulders with one one in the hall? And let's not forget the way she dodged that lacrosse ball - no human could move that fast!

"Try to tell me I'm wrong here," Stiles finishes his lecture, panting with exhilaration. He had done it, all the facts were laid out and Scott could not deny the simple truth that he was slowly warming him up to.

Sure his evidence was not air tight, but there were too many things lining up for this to all be a coincidence.

His best friend however, does not seem to be in agreement, "You're wrong here."

"Wha- how?!" He demands.

Slowly, Scott refutes, "Okay.. so firstly? you've heard the rumors dude - you know she has an eating disorder right? And, um, she's nice and she's mourning so, like, why wouldn't people be nice to her"

"What about the other stuff?"

"Dude, you're looking to much into this."

"But-"

"What do you think she's a vampire or something?" His friend laughs.

Stiles looks to the ground, not knowing what to say.

Scotts' not laughing anymore. "Dude."

"It's a possibility!"

"No, it's not! Are you forgetting that vampires aren't even real?"

"But, maybe that's just what they want you to think!"

"You cannot be serious."

"Scott, You can't tell me you're not suspicious at all. Just think about all the weird things I told you about!"

"She's a girl, man. Girls are weird."

No matter what Scott said, Stiles knew that Natalie McCarthy was more than just weird.

Regardless of her intention here - he starts carrying around a stake and a cross, just to be safe.

What do you think? This is only part one of the prologue, as I'm still deciding on a few things (like should she use Isaac as a walking blood bag? lol) so I'm leaving it here for now. And potentially forever.
