Hi everyone! Thank you so much for checking out my story! This is a pretty heavy Vampire Diaries crossover, mostly through flashbacks. This story starts in season two of Teen Wolf and I have already written through that whole season, it's just a matter of editing. I highly suggest watching The Vampire Diaries, as there are two whole chapters dedicated to that, as well as numerous flashbacks. My character Annabelle is also a singer, so there are a lot of song lyrics mostly from Billie Eilish in here. If you have any questions, please review! Thanks!

DISCLAIMER: I do not own any content from Vampire Diaries or Teen Wolf. I also do not own any lyrics used from any artists in this fan fiction. Enjoy!

CHAPTER 1

Annabelle walked slowly up the steps to her new school, sighing heavily and thinking of her friends back in Mystic Falls. She hoped that Caroline was doing okay as a vampire, that Katherine had left town and everyone was safe. Things had been left in a bad place but Annabelle had no choice but to leave when her brother got a new job in Beacon Hills. She paused when her phone buzzed and glanced down to see a text from Bonnie.

Don't worry about us, have a good first day. Love you!

Annabelle smiled at her words and sent a quick text back. As she was typing, two boys passed by her and Annabelle couldn't help but listen in.

"She ate the liver?"

"I didn't say she ate it, I said it was missing. And if she did, so what? It's the most nutritious part of the body," the boy said with frustration in his voice.

Annabelle frowned and followed the two boys into the school.

"I never ate anyone's liver," the other boys said. He had the voice of a typical nice guy and a mop of brown hair.

"Oh right, because when it comes to werewolves you're a real model of self-control," the guy said with a roll of his eyes. Annabelle froze and digested what she just heard.

Great, out of the frying pan and into the fire, she thought. She looked at the two boys again and saw that they had stopped too, but were still talking. She cleared her throat and glanced at the lockers around her, quickly finding hers. It happened to be right next to them and they glanced at her as she came up.

"Sorry, my locker is right here," she said while pointing.

"Oh no worries. Are you new here?" the boy with the kind eyes said while looking at her carefully. Annabelle just nodded carefully before pulling open her locker and throwing some books and her lunch in.

"I'm Scott, this is Stiles," he said while gesturing to the boy with the buzzcut.

"Annabelle, nice to meet you," she said with a friendly smile.

The two boys walked off after that and Annabelle turned back to her locker, not noticing when Stiles looked back at her.

First class of the day was history and Annabelle was bored out of her mind in the back row since she had already learned the material. She started writing lyrics but quickly stopped and just stared as she spun her pen on her desk. After a quick glance around, she lifted her hand and watched as her pen continued to spin on it's own and smiled. She sure did love magic. She continued to watch as the teacher blathered on, not even noticing as Stiles turned around to ask if she caught what the last slide was. He stopped short and watched as the pen spun on it's own, looking up at the girl in confusion. Her green eyes were staring absentmindedly at the pen, loose brown curls golden in the sun filtering through the windows. For a moment Stiles was distracted by how beautiful she was before looking back down at her pen again. Suddenly her green eyes locked with his brown ones in alarm and she slammed her hand down, effectively stopping the spinning. Everyone turned to look at them and Annabelle cleared her throat awkwardly as Stiles turned back around, opening her notebook and pretending to take notes. When the bell rang for next period, she was the first one out the door.

Before last period, Annabelle walked quickly to an empty classroom and pulled her phone out, dialling the familiar number quickly.

"What?" an annoyed voice on the other line said.

"Chill, I just have a quick question Damon," Annabelle said with an equally annoyed voice.

"Well my patience is thin, so let's hurry it along".

For a split second, Annabelle wondered what she ever saw in the cranky vampire.

"What do you know about werewolves?" Annabelle said, looking around to make sure the boys in question weren't around.

"Funny you should mention that, we have a bit of a wolf problem right now," Damon said.

"What? Why, what's going on?" Annabelle said worriedly.

"The Lockwoods are a family of werewolves. The Mayor's brother Mason just showed up and is causing problems. What's wrong with you?"

"I heard two boys at my school talking about it. How do you spot one?" Annabelle said quickly.

"Easy, get them angry. They'll have enhanced strength and a short temper. Would you listen if I told you to be careful?" Damon said.

"Not even if you cared. Thanks," Annabelle said before hanging up. She left the room quickly and turned into chemistry, taking a seat in the back row again. She was thrown back into a memory from about a month ago rather abruptly.

Annabelle leaned against the wall of the Lockwood mansion and watched disinterestedly as people danced to classical music and made small talk. These events always bored her, but she had to make an appearance if she wanted any hope of winning the Miss Mystic pageant next week.

"There she is, how's my favorite witch?" Damon said while throwing a sarcastic smile at the brown-haired girl. She didn't spare him a glance as she took a sip of her spiked coke.

"You only like me when you need something. What is it?"

He glanced down at her, noting her tight black dress and high heels, the way her loose curls tumbled down her shoulders to the middle of her back and hummed in appreciation.

"Nothing related to your witch expertise at the moment," he said while looking back out at the room. Annabelle glanced at him in wary surprise, raising an eyebrow suspiciously.

"I need a distraction, dance with me?" he said while holding out a hand. Annabelle thought about saying no, but then she looked at his face. His handsome blue eyes were soft which was a rare occurrence, especially when they were pointed at her. She took his hand and he spun her onto the dancefloor, grabbing at her waist and holding her close. Sure they had jokingly flirted in the past, but Annabelle knew that he was in love with Elena. Still it felt good to have his attention on her and she would be lying to herself if she said she wasn't interested.

"Do you mind if I sit here?"

A voice disrupted the hazy memory and Annabelle looked up to find a tall boy with blue eyes looking at her expectantly.

"Not at all, please," Annabelle said while gesturing to the seat at her table. Just as he was sitting, the two boys from this morning walked in.

Scott and Stiles, Annabelle reminded herself.

"Is this yours?" the boy next to her asked. He was holding out her worn lyric journal.

"Yes sorry," Annabelle said while taking it quickly. Her hand brushed his and she sucked in a breath as an image flitted across her mind. It was the boy next to her, but with glowing yellow eyes.

Werewolf.

He looked at her questioningly and she gave a hesitant smile as she held out her hand.

"I'm Annabelle by the way," she said while he took her hand in his. That same feeling overtook her and she was sure after that.

"Isaac," he said with a handsome smile.

They both turned to the front after that and paid attention to class. Annabelle caught Stiles looking at her on more than one occasion, noticing how fidgety the boy was. There was a pop quiz announced and Annabelle was glad that she had already taken this class in Mystic Falls.

She was just answering the 3rd question when there was a commotion up front.

"This is a pop quiz Mr. Stilinski. If I hear your voice again, I may be tempted to give you detention for the rest of the year."

Annabelle snorted at this but didn't look up from her quiz.

"Can you do that?" she heard Stiles say.

"There it is again. Your voice, triggering the only impulse I've ever had to strike a student. Repeatedly and violently. I'll see you at three for detention."

Annabelle raised her eyebrows at that, surprised a teacher was allowed to get away with speaking to a student like that. Still, she kept her head down and the rest of classes finished without any unforeseen events.

Finally home, Annabelle glanced at the note left on the fridge by her brother.

Gone for the week, dinner's in the fridge.

She pulled it off and tossed the note in the trash with a sigh. With James' new job an hour away, he had mentioned her being alone a lot during the week.

She lit the fireplace in the living room and sat in front of it to do some homework, making quick work of it. Then she pulled out her laptop and continued working on the song that she had started in Mystic Falls.

I should never think

What's in your heart

What's in our home

So I won't

You'll learn to hate me

But still call me baby

Oh love

So call me by my name

And save your soul

Save your soul

Before your to far gone

Before nothing can be done

Annabelle had written it in response to her time with Damon. While they had never officially put a label on anything, Annabelle was still hurt by the way he had looked at Elena. The song was about a relationship that was toxic and yet no one could walk away. For some reason, that was the case with her. Maybe she deserved that sort of relationship. Annabelle wasn't sure, but she thought about it until she fell asleep that night, hoping she wouldn't make the same mistakes here.

The next day, Annabelle got up early and went to the spare bedroom to train. As she spun and kicked the punching bag in front of her, she was pulled into another memory from Mystic Falls.

"You're small so you need to focus on speed and momentum. You won't get anywhere from trying to punch the hardest or be the strongest. You need to be smarter than your enemy."

Annabelle narrowed her eyes and did the move again, focusing on being faster.

"That's better, now let's spar a bit," Mr. Saltzman said with a sharp nod.

"Thanks Ric", Annabelle said with a grin before dodging a punch and going for his legs with a grunt.

At school Annabelle stood by her locker, watching as the entire student body turned while two girls, one with red hair, one with brown, walked through the front doors. Annabelle heard the whispers but decided to ignore them, feeling sorry for the girl they were talking about, her name Lydia Martin.

In history Annabelle pulled out her notebook, doodling more lyrics while listening to another lecture. She met deep brown eyes yet again as Stiles looked back at her for the fourth time in 20 minutes.

"Can I help you?" Annabelle whispered at him with irritation.

"Nope, no sorry," he said loudly before turning back around. The history teacher gave us a warning look before turning to write on the board again. Annabelle thought for a moment, weighing her options before sucking in a breath.

"So is that girl who went streaking through the woods really a werewolf?" Annabelle whispered quietly.

Stiles turned around so fast that Annabelle thought he would get whiplash and she raised her eyebrows and smiled with amusement. He glanced at her dumbfounded for a moment.

"How do you know about that?"

"Well you aren't exactly quiet when you talk in the hallways. You really should be more careful," Annabelle said, smiling still.

He opened and closed his mouth a few times, trying to find the right words to say. It didn't help that Stiles kept getting distracted by the spark in her green eyes when she looked at him.

"Well you should be more careful with your little party trick," he said while glancing pointedly at her pen where it sat on her desk. She smiled at him amusedly before sitting back in her seat.

"I suppose that's true," she said calmly. Stiles stared at her for a moment longer with narrow eyes and she stared back.

"What are you?" he said loudly. The history teacher cleared his throat loudly and all eyes were on them.

Annabelle watched as Stiles and Scott walked into chemistry, Stiles watching her suspiciously. She just sat back in her chair and smiled back, waggling her fingers at him in greeting.

"What did you do to him?" Isaac asked with amusement. Annabelle looked at him and her heart stuttered at the smile he gave her.

"Nothing yet, that's why he's on edge," she said with a shrug while getting her notes out for class.

"Oh?" he said with a suggestive raise of his eyebrows and a mischievous smirk on his face.

"Not like that," Annabelle said, shoving him in the arm playfully. She didn't know why she felt so comfortable around Isaac so quickly. Perhaps it was the fact that she knew his secret, or maybe it was the playful glint in his eyes. Either way, she found herself liking him.

"Well good," he said while smiling up at the front. Annabelle looked at him questioningly, but he just kept looking at the board. She smiled while looking at the front as well, writing the topics for today in her notebook.

The bell rang and Annabelle quickly got up from her seat and texted her brother to check in. She remembered hearing something about lacrosse practice and knew that Isaac was on the team so she headed to the field to check out how lacrosse even works. She walked up to the bleachers, slipping past Stiles and Scott unnoticed as they sat on the seats by the field getting ready.

"...It's kind of like a scent, but I couldn't tell who." Scott said.

"What if you could get him one-on-one," Stiles countered.

Scott nodded and Stiles promptly rushed over to another boy and started talking to him. A couple minutes later, he came back with a bunch of goalie pads in his arms.

"I told coach you're switching with Danny," Stiles said slightly out of breath.

"But I hate playing goal," Scott said.

"Remember the part where I said I had a plan? This is the plan," Stiles said while gesturing to the pads.

"Oh...what's the plan?" Scott said, his face twisted with confusion. Annabelle laughed at this and sat back in the stands, watching this disaster pan out.

"I seriously don't know how you survive without me," Stiles said while looking around for the source of the laughter. He locked eyes with Annabelle and turned back to Scott before freezing and looking back over at Annabelle after comprehending who it was.

"How are you always around?" he shouted to her. She just shrugged and looked at the other players on the field. Annabelle spotted Isaac and he waved at her with a smirk. She waved back and then they were off to practice.

Annabelle watched as Scott left the goal and raced up to the first player and slammed into him, giving a great sniff to try and figure out if that was the other wolf. Annabelle watched in amusement as he repeated this several times, getting weird looks and jabs from the coach.

Stiles went and grabbed some water from the bench they were at and Annabelle got up and sat next to him. He was watching Scott so closely that he didn't even notice her until she cleared her throat loudly. He jumped and glared at her before settling down.

"What do you want?" he said rudely. Annabelle ignored this and watched him carefully.

"You know if you want to know who the other werewolf is, all you have to do is ask."

He turned and looked at her with amazement.

"You know who it is? How?"

"Not important. I figured it out yesterday," Annabelle said while looking at her heeled boots smugly. Stiles was silent for a moment before gesturing for her to continue, but she stayed silent.

"Well? Who is it?"

"What will you do when you find out?"

"Why do you care?"

"Why wouldn't I care?"

He was quiet again after their banter, sighing in frustration. She watched him get up and start to head back onto the field.

"Hey!" Annabelle shouted at him.

He turned around and walked a few steps toward her.

"It's Isaac Lahey, number 14." Annabelle said quietly.

Stiles' eyes widened before he turned and watched as Isaac took a step up towards the goal. The two wolves ran at each other and Annabelle watched in fascination as they slammed into each other, spinning in the air and landing in defensive crouches. Stiles' jaw dropped open and he turned back to Annabelle. She just raised her eyebrows at him and got up to stand next to him and watch.

Suddenly everyone's attention turned to the edge of the field and Ananbelle watched as a sheriff and two deputies walked up to coach.

"What's going on?" Annabelle asked Stiles.

Scott ran over to them and shot Annabelle a look.

"She's fine, what happened?" Stiles said.

Scott shot her another look but trusted Stiles and told them both what happened on the field.

"Can you hear them?" Stiles asked.

"His father's dead," Scott said.

"Are you kidding?" Stiles responded and Annabelle watched Isaac's reaction closely.

"They think he was murdered," Scott said as Isaac was ushered off of the field.

"Did they say he's a suspect?" Annabelle asked quickly. She ignored the look Stiles shot her.

"I don't think so, why?"

"Because they can lock him in a holding cell for 24 hours," Stiles explained.

"You mean like overnight?" Scott asked.

"During the full moon," Stiles finished. Annabelle sucked in a deep breath and watched Isaac with concern. She hadn't known him very long, but he didn't look like the sort of kid who would murder his own father.

"How good are the holding cells at holding people?" Scott asked.

"People? Good. Werewolves? Probably not so good," Stiles explained.

"Stiles, remember how I said I don't have the urge to maim and kill?"

"Yeah."

"He does," Scott finished, and they looked at each other in concern.

Annabelle caught Stiles heading to his blue jeep before the end of the day and stepped in front of him.

"I want in," she said firmly.

"In on what?" he asked as he tried to walk around her. Annabelle just stepped in front of him again, this time placing a hand in front of his chest, pushing it slightly. Stiles' heart sped up at the sight of her, hand held out in defense, brown curls bouncing around her as she stopped him again.

"Whatever the plan is to help Isaac," Annabelle said with determination.

"Look there is no plan, and you wouldn't be much help anyways," he said before successfully passing her and opening his car door to toss his backpack in.

"That little 'party trick' you saw the other day? I can do more than just that," Annabelle said before grabbing his car door before he could slam it shut in her face. Stiles looked back at that and saw the steely look in her deep green eyes.

"What do you mean?" he asked.

Annabelle held eye contact with him while focusing on the sky. As they watched each other, the wind began to pick up and the sky darkened. There was a deep rumble of thunder from a distance and leaves swirled around them. Just as soon as it had started, the wind calmed and Annabelle watched him closely.

"Did you do that?" he asked bewildered.

"I can help you if you'll let me," Annabelle said with conviction. Stiles stared at her in fascination before finally sighing and throwing his hands up in the air.

"Get in then," he said quickly and Annabelle smiled.

Annabelle held on to the edge of her seat in fear as Stiles drove at an insane speed while on the phone.

"Harris literally just let me out of detention. Literally. And he had my phone the whole time." he said in frustration.

"Well we need to do something right now. They were asking me all these questions about Lydia and how she was bitten by Peter. And then they sent this guy out-" Annabelle heard just barely from Stiles' phone.

"What guy?" Stiles interrupted with.

"He was dressed as a sheriff's deputy."

"They must be sending him to the station for Isaac," Annabelle said quietly and Stiles reiterated that to Allison.

"He was also carrying this box and there was something on it. Like a carving," Allison explained.

"What was it?" Stiles asked.

"Hold on, it's in one of the books. I'm taking a picture," she said while shuffling around.

"Wolfsbane," Stiles confirms after looking at the picture briefly.

"What does it mean?" Allison asked. Annabelle rolled her eyes at the stupid question.

"It means she's going to kill Isaac, genius," Annabelle yelled at the phone. Stiles sent an amused but annoyed glance at her.

"Who's that?" Allison responded with.

"It's Annabelle, she's in our chemistry class" Stile responded shortly.

"Whatever, I can slow him down if you can get to the sheriff's station on time," Allison said quickly.

"Got it," Stiles said before hanging up and pushing down even more on the accelerator. There was silence in the jeep for a bit before Annabelle's curiosity got the better of her.

"So who's Peter?"

Staples looked at her but didn't say anything. Annabelle rolled her eyes and sat back in the chair.

"I'm here to help Stiles, but I need all of the details."

Stiles ignored the way his heart stuttered when she said his name.

"Peter was the alpha before Derek, who turned Isaac. He was crazy and a murderer. He also turned Scott." Stiles explained.

"And I'm assuming this Derek guy killed Peter to become alpha?" Annabelle asked.

"Yeah, how much do you know anyways?" Stiles asked, glancing at her suspiciously.

"Not a lot. I came from a town called Mystic Falls, we have a lot of supernatural creatures there too, though not a lot of werewolves."

"You mean there's other stuff out there besides werewolves?" Stiles asked with a panicked expression. Before Annabelle could respond, Stiles' phone rang and he picked it up. Scott explained the plan and Stiles seemed reluctant but agreed. Then he called and checked in with Allison before pulling up to the deputy station.

Suddenly the door to the passenger side opened and Annabelle jumped in surprise. A man with blue eyes and a dark beard looked up at her in annoyance, then looked at Stiles.

"Who the hell is this?" he said rudely.

Annabelle scoffed at that and opened her mouth to respond, but Stiles beat her to it.

"Annabelle, she's here to help. Get in Derek," he said shortly. Derek climbed into the backseat of the jeep and they brainstormed ideas quickly.

"The keys to every cell are in a password protected lockbox in my father's office," Stiles explained.

"Your father's the sheriff?" Annabelle interrupted.

"How are you getting in the lockbox?" Derek said while ignoring her. Annabelle narrowed her eyes in annoyance and Stiles shot her an apologetic look.

"My father's got two passwords, my birthday and my mother's birthday. The problem is getting past the front desk," he said quickly.

"I'll distract her," Derek countered.

"Woah woah, you? You can't go in there!" Stiles responded.

"I was exonerated," Derek said matter-of-factly. Annabelle raised her eyebrows at this.

"You're still a person of interest."

"An innocent person."

"You? Yeah right."

"You're not getting in there without me."

"Okay, what's your plan?"

"To distract her."

"How, by punching her in the face?"

"By talking to her."

It was like watching a tennis match and Annabelle was getting whiplash going back and forth between the two of them.

"Oh obviously. Because when I think of diverting conversation or stimulating banter, I think of Derek Hale," Stiles said sarcastically and Annabelle smiled at him as Derek glared.

"At least give me a sample. What are you going to open with?"

Derek continued to glare at him and I giggled.

"Dead silence. That should work beautifully, don't you think Annabelle?" Stiles asked, turning to her.

"Oh absolutely Stiles, 100%," Annabelle said with a smirk.

"Any other ideas?" Stiles asked.

"I'm thinking about punching you in the face," Derek said shortly. Annabelle and Stiles simultaneously rolled their eyes at that before they all got out of the car and headed towards the front door.

Annabelle watched as Derek charmed the lady at the front desk and her and Stiles slipped past unnoticed. He heads to the lockbox in the sheriff's office and types in the code, giving a satisfied smile when it pops open. That smile quickly drops when they notice that it's empty and they both turn for the hallway.

"Go check on Derek," Stiles ordered and Annabelle didn't argue as she turned towards the front. Noticing that he was still chatting up the lady at the front desk, Annabelle gave a satisfied nod and turned back to look for Stiles. She paused when she noticed drops of blood on the floor and switched to a run as she went in the direction that she assumed the holding cells were. Just as she reaches the door, Isaac jumps onto the hunter dressed as the sheriff's deputy and slams him into the wall. Annabelle's eyes widen, but she quickly turns to find Stiles on the floor and runs to him.

"Are you okay?" she asks quietly and he nods as he watches Isaac incapacitate the man. He slowly turns and his glowing yellow eyes show no recognition of the two of them as he takes a step towards them.

Annabelle stands at her full height and glares at the wolf, though this doesn't look very impressive since Isaac is over 6 feet tall and Annabelle is barely over 5 foot. He starts to run at her and she lifts her chin as he stops dead in his tracks and collapses, grabbing his head and crying out in pain.

"What are you doing?" Stiles shouts.

"Giving him an aneurysm. Don't worry, he heals," she said shortly before stopping. Isaac breathes heavily before looking up at her, his eyes back to normal.

"Annabelle?" he asks quietly. Derek takes this time to run in and notices Isaac on the floor with Annabelle in front of him. He looks at her inquisitively before reaching for Isaac and pulling him out the door.

Annabelle turned to Stiles and offered him a hand up, which he took gratefully.

"How are you able to do that?" he asked in awe.

"Simple, I'm a witch," Annabelle said with a smirk before following Derek and Isaac out the door, leaving Stiles there to gape at her.
