Disclaimer: not mine, blah blah blah... ok, Cat is...but none of the known characters from Arrow or Teen wolf belong to me.

AN: here's my new xover story... enjoy... let me know what you think, ie, do i continue?

if you have any questions about Arrow, just ask... but below is a little rundown thus far.

The series follows Oliver Queen, billionaire playboy of Starling City, who spends five years stranded on an island following a shipwreck that claims the life of everyone else on board, including his father, Robert Queen. Upon his return to Starling City, he is reunited with his mother, Moira, her new husband, Walter Steele, the then-current CEO of Queen Consolidated; and his younger sister, Thea. His best friend, Tommy Merlyn, the son of billionaire Malcolm Merlyn, and ex-girlfriend Laurel Lance, also greets him. The first season focuses on Oliver reconnecting with people upon his return, and spending his nights hunting down the wealthy responsible for "failing the city" as a hooded vigilante who is not afraid to kill his targets. He becomes at odds with a secret organization that plans to destroy the Glades, a section of the city that has become overridden with crime. John Diggle, who acts as Oliver's bodyguard in front of the public, and Felicity Smoak, an IT specialist who works at Queen Consolidated, assist Oliver in his crusade. The first season also features flashbacks to Oliver's time on the island, and how it changed him; this continues in the second season.

In season two, Oliver is driven to stop crime without killing criminals, motivated by the death of his friend Tommy. Tommy died when the Glades were destroyed by an earthquake machine made by Queen Consolidated. Moira was in on this with Malcolm Merlyn and when she came forward and confessed what happened, they tried to stop it but Malcolm made sure the earthquake at the Glades happened.

Now, let's see what happens when Cat arrives….

... ... ...

Cat closed the computer with a frown before turning towards the bathroom. She had arrived the night before in Starling City and her first order of business was to stop at the nearest shopping outlet before getting a motel room, paid in cash of course. She had to meet Felicity at Queen Consolidated the next morning and until then, she had to make herself look very un-Cat like. That part had already begun when she stopped by a hair dressers and had her blonde locks chopped off. She had a pixie style hair cut and had gone to buy some box dye right after. Her hair was now a dark ruby red and when she looked in the mirror, she no longer recognized herself. After she had bought some clothes befitting of an office environment and now she picked through those, trying to decide what to wear for her first meeting. Finally deciding on some clothes, she changed and began doing her makeup, trying to make her appear a little older. She was almost 18 but Felicity had lied and said she was older in order to get her the job. Not many people wanted to hire a high school junior, even if they were a computer genius.

When she was done, she packed up her meager belongings and went out to her SUV, contemplating yet again on whether to trade it in or not. She didn't want to be traced but at the same time, that SUV had been tailored to fit her needs with its many secret compartments to hold weapons. What was the point of getting a new car and fixing it to suit her needs when she was unsure if she would even be alive in a month to use it?

Cat reached under the seat, feeling for the gun she kept hidden there, this one contained one bullet chock full of wolfsbane and she would use it on herself once she figured out what it was that Felicity needed help with. As long as she could stay sane for that amount of time.

She just couldn't believe what her life had come to. Just a few short days ago, she had been the most powerful Seer to come along in ages. But in trying to take out the most recent enemy, she had been bitten by an Alpha werewolf. If she was any normal person, that would've meant she would either survive and become a werewolf or reject the bite and die but because she was a Seer, her options were limited to insanity or killing herself. Seers were not meant to become werewolves. The only known instance of this happening had made the Seer go off the deep end and savagely kill many packs and villages before an alpha pack of werewolves had taker her out. And from the sounds of it, she was nowhere near as powerful as Cat was, meaning, it would be next to impossible to stop her.

Her friends didn't want to hear it though. They were determined to save her at all costs, promising to find a way, even after she begged them to kill her. Scott McCall had refused. He had been the one to bite her, totally by accident of course, when the Nogitsune, the evil fox spirit, had pulled her in the way before Scott could bite him. Cat had maneuvered them so this Nogitsune also was bitten, therefore killing him but the damage to Cat had already been done. She had even gone so far to try and off herself but Stiles, sweet, wonderful, amazing Stiles had stopped her. She wouldn't let anyone kill him when he had been possessed and he refused to let anyone, herself included, kill her. He promised they would find a way. But Cat only saw this ending one way so she had distracted him with a kiss before knocking him out and taking off. He could hate her all he wanted but she would rather he hated her then for him to end up dead because of her.

Cat had contemplated killing herself the moment she left him, except the dreams she had been having for a while kept plaguing her and she realized she had to go help her old friend Felicity like she had promised in her dreams. For reasons unknown to her yet, Felicity had been begging for help and Cat knew she had until the next full moon to find out before she really lost it, she just hoped it was enough time to help.

Checking the time, Cat realized it was probably time to head to Queen Consolidated to meet Oliver Queen and to finally see Felicity face to face. She had met the older woman online years ago and Felicity had taken her under her wing so to speak and taught her everything she knew about hacking. Cat had since surpassed that but had been out of touch with Felicity since the shooting at her school that had activated her powers and brought her to Beacon Hills. She didn't know Oliver Queen, hadn't even heard of him until she looked Felicity up but it didn't take her long to learn about him. Wealthy playboy who was on a boating trip, the boat had capsized and everyone believed there to be no survivors, that was until Oliver Queen was discovered on an uninhabited island five years later. He had returned home and began learning the family business, until his mother admitted to conspiracy and caused a huge earthquake in the bad part of town. Moira Queen had had just been acquitted, where the prosecution was seeking the death penalty and Cat could only imagine what kind of effect this was having on her children. Perhaps they needed her help and that's why she was there. Unfortunately, it wasn't like she could use her psychic powers and find out, ever since the bite, Cat's powers had been…well basically nonexistent.

When she arrived, she spoke to security who gave her a badge and directed her to the proper floor. When she arrived on said floor, the elevator opened to show Felicity standing there a big grin on her face, which faltered when she took in the girl in front of her.

"Lina?" the Blonde warily asked, not quite recognizing the girl in front of her. She hadn't seen a recent picture and all she remembered was a young looking girl with mousy brown hair, eyes huge behind the glasses she had worn in the photo, her clothes were definitely the style of someone who really didn't quite care. Now, her hair was very short and dark ruby red, gone were her glasses, her eyes still big though and the color of a tropical sea. She was still as petite as she had appeared to be in pictures but possessed the confidence of someone a foot taller, her head held high, grace in every step as she walked towards her.

"City." Cat grinned, using her old nickname. When they had first met, neither girl had called each other by their full names, opting to use the endings as nicknames. In fact, Cat was positive that Felicity didn't even know anyone called her Cat.

"You're so grown up now." Felicity cried, "Can I hug you?"

"Of course." Cat replied, stepping forward and throwing her arms around the much taller girl.

"Oliver can't wait to meet you." Felicity said after they had broken apart.

"Do I look okay?"

The blonde looked her over before nodding in approval. Cat was wearing a black pencil skirt with a fitted blazer over an emerald green top. The front part of her hair was pushed back with a headband, leaving her face open, her eyes sparkling under the light purple makeup she was wearing on her eyelids. On her feet was a pair of high black stiletto's that must've given her an extra 4 inches but still she appeared tiny and Felicity felt like a giant next to her.

"You look great." Felicity assured her, leading the way down the hall to the main office. "Oliver is really awesome to work for."

"I bet if you're on a first name basis." Cat replied with a smirk as they walked into the office.

The big leather chair at the desk spun around and a man who looked to be in his mid-twenties stood up, a big welcome smile on his face as he walked towards them. Cat's breath caught in her throat. She had seen him in pictures when she was doing research but that still didn't get her ready for seeing him in the flesh and she had to fight to not let a blush creep onto her face. Stiles, she would think of Stiles.

"You must be the one Felicity spoke about." He said, holding out a hand.

"Yes, I'm Lina Calhoun." She softly replied, reaching out to hesitantly take his hand. She steeled herself for any visions she might get off of him but when they touched, nothing appeared. And she forced herself to not let out a frustrated sigh. She knew there was something crazy when she wished she would get some random vision.

"Calhoun?" Felicity asked with a frown.

Cat nodded. "It was my mothers name. I legally changed it after my dad abandoned me and I became emancipated."

Oliver's eyes shot up. "Emancipated? Your dad abandoned you?"

She couldn't stop the laughter from escaping. "Yeah, after he tried to kill me and all but that's a fun story for another time."

Oliver and Felicity exchanged a quick look.

"Don't worry, I'm as sane as anyone else. I've been looking after myself for a long time." Cat told them, silently adding that she didn't know how much longer she would be sane for.

"How old are you?" Oliver hesitantly asked. "I know Felicity said you weren't too far removed from high school but you look like- well like you just started high school."

Cat shrugged. "I get that a lot. But I'm 22." She easily lied. "You'll be needing this anyways for paperwork, so here you go." She pulled out her new, realistic fake ID and handed it off to him, seeing him look over it before handing it to Felicity.

"So is Lina short for anything?"

"Yeah, but I only go by Lina. Is this part of the interview?" She asked.

He grinned, already taking a liking to her. "No, there is no interview. You already have the job. Felicity will give you a rundown of everything she used to do, I'm sure." He looked behind her and Cat turned around to see a tall dark skinned man standing there. Him and Oliver exchanged a look before Oliver spoke again. "I have to attend court. Felicity, I'll call you when you're done.

He left with the other man and Cat turned to look at the other woman. "He seems… cute."

"He really is." His assistant replied, looking after him. She shook her head, turning to the newest employee. "I'll show you everything I used to do. We set up a temporary desk near me just until your caught up to speed and then you'll be moving to the IT department."

Cat nodded as she looked around, stepping up to the window to look outside. She looked over the city, her eyes stopping on one particular spot. "Is that where the earthquake happened?"

Felicity stepped up beside her with a small frown on her face. "Yeah, it is. It looks a lot better than it used to, which is kind of sad."

"Did you lose anybody in it?"

"People I knew, yeah. No one I was close to. Oliver lost his best friend in it, whose dad was the one who-"

"Malcolm Merlyn." Cat finished, noticing the appreciative look Felicity shot her. "What? I know how to do research too."

"Of course, I taught you after all. Come on, let's finish getting you set up."

… … …

Cat stood in the middle of her new bedroom, looking around to make sure all the weapons she hid were still well hidden. When she was convinced they were, she opened the door to the spare room and stuck her head out, listening for any sounds of Felicity. The older woman had dropped her off here, given her a quick tour and told her to make herself at home before taking off again, saying she had a work emergency. Deciding that she was very much alone and Felicity was still gone, she went back into her room, slipped on a pair of black yoga pants along with a black hoodie before grabbing a beanie and tucking her red hair up into it so she would be less noticeable. She strapped on various weapons, deciding to leave her guns behind and taking her bow instead. She planned to stick to the shadows and some of the rooftops just so she could check out town, see if she could learn anything more, perhaps see if she could see what went down after dark. Maybe even find the local pack, if there was one. That way, she would know who to positively, absolutely, stay away from. While the alpha pack had disbanded and had no intention of killing her, she didn't know if word got around to packs around the world that she was now safe and she liked her head attached to her body thank you very much.

Then again, was there really anything for the local pack to kill her over? She didn't know what she was anymore. She once had the ability to see dead people, to read others thoughts, to learn something about someone just by a touch but had yet to do that since she had been bitten. At the same time, she didn't feel like she would be growing claws and wanting to tear people apart with her teeth.

When she was done, she poked her head out of the room again and still not hearing anything, closed and locked her door, making her way to the window and out to the fire escape. She had always wanted to use one of these and now, living with Felicity, she would get the chance to whenever she wanted to sneak out. She didn't want her mentor to start questioning her extra curricular activities, at least not until she knew more about what brought her here. Maybe Felicity did know more about her life in Beacon Hills then she let on but Cat wasn't about to share just yet. It was only her first day and with no powers telling her what to do, she was in this blind.

Her phone began buzzing in her pocket just as she reached the roof and she pulled it out, cursing herself for forgetting to get a new one. Until she did that, she needed to leave it on for Felicity. As far as she knew though, she was okay from her friends trying to track her down through her phone. She was the computer wiz and was the one to usually do anything like this for them. Allison could, but Allison was... gone. Not recognizing the number, she hit the answer button and put it to her ear.

"Hello?"

"Where are you?"

Cat sighed and shook her head, unable to believe she had fallen for this. "Where are you calling from?"

"It doesn't matter." Stiles replied. "Where are you? I'm coming to see you."

"Stiles, you can't." She quietly told him.

"Cat." He begged her. "I want to be there for you. Please, just let me be there for you. I'll come there, I won't tell anyone, I swear."

Cat closed her eyes, fighting back the tears struggling to break through. "I can't. I'm helping Felicity."

"I can help too."

"No. I'm helping her because I promised but then- but then-" She faltered unsure of how to finish her thought.

"You plan on killing yourself." He stated, his tone flat.

"Before the next full moon. I'm not- I'm not me anymore Stiles. I don't have- I can't see- I'm just not me and I don't know what I am, I just know I have to be put down before it's too late."

"You're wrong and I'm going to keep looking until we figure out how to fix this."

A tear trickled down her cheek. "Stop trying to save me, Stiles."

"No." He cried. "You wouldn't stop trying to save me and I'm not going to give up on you. You say you're there to help your friend right? Because you promised her in a dream, a dream she's probably not even aware of. What about the promise you made to me?"

"What promise?"

"That you'll come back here after you were done there."

"That was before." She argued. "Stiles, you know I can't keep that anymore."

She heard him sigh. "That's bullshit, Cat."

"Stiles, if I see you again, I don't think I could through with it and I have to. I could never forgive myself, crazy or not if I hurt you or anyone."

"Fine, then promise me this, before you do anything completely stupid because you think you have no choice, give me a chance to find a way to save you."

She grew silent, contemplating what he said.

"Please." He whispered. "Just please give me the chance."

She couldn't do it, she couldn't tell him no again. "Fine, you have until the full moon."

He breathed a sigh of relief. "That's all I need, trust me."

"You can't tell anyone where I am."

"Cat, I don't know where you are. You have to keep your phone on though, no disappearing."

"Fine." She grudgingly replied. "You can't tell anyone we've spoken. Not yet, I don't want them to come looking for me."

"You don't have to do this alone."

"Yeah, I do." She whispered, just as a distant scream reached her ear. "I need to go. I'll talk to you later."

She took off running before she had even hung up the phone, leaping for the next rooftop. Okay, so she didn't exactly have her Seer like powers anymore but all the physical aspects were still there, maybe even slightly improved if she would look further into it, which she wouldn't, she wanted to put off the whole werewolf transformation as long as possible, if she could.

She continued running, jumping over several rooftops before she heard the screaming again, this time just below her. She looked over the side to see a woman screaming as a group of men pushed her around. Cat pulled her hood up as she jumped over the edge, grabbing the fire escape with one hand as it took her to the ground. With the other hand, she pulled off her bow and the moment she touched the ground, she turned, shooting an arrow and hitting one of the guys in the shoulder.

The first guy groaned in pain, yelling that the hood was there and causing the others to turn to her. One of the guys grabbed the woman, pulling her closer and Cat stepped towards him, punching him hard so he loosened his grip. She told the other woman to run and she complied, leaving Cat alone with the rest of the men. She turned with her bow, grabbing an arrow and notching it as she stared at them, challenging them with her eyes. One guy moved towards her and she waited until he was close enough, striking out with her elbow and catching him in the side of the head. At once, the other guys came at her and she began fighting with all her might. Sure, she was stronger than most but she still didn't have the hang of all she could do now and with five guys, they soon got the upper hand, one grabbing her around the throat, slamming her against the wall and promising to make her pay. She was about to head butt him when an arrow that wasn't hers, embedded itself in the guy's arm. He dropped her with a cry of pain just as a man with a hood covering his face arrived on the scene, punching and kicking the guys, taking them out one by one. Cat watched with an appreciative gaze as he turned towards her.

"I won't allow copy cats in my city." He told her in a deep voice and Cat tried to get a closer look at him but to no avail. That wasn't his real voice, he did something to make it lower if that's how he wanted to play, fine, she could play that game too.

"I copy no one." She replied, lowering her own voice.

"You have a hood and a bow and arrow and you're trying to tell me you're not copying?"

"What are you, three?" Cat couldn't help but ask.

"Who are you?" the hooded guy asked.

"I'll show you mine if you show me yours." She taunted.

"Both of you, drops your weapons and put your hands in the air." A voice from the entrance of the alley yelled at them.

Cat glanced over to see a police officer with his gun raised at them.

"Next time?" She asked, not giving the other guy a chance to answer as she notched another arrow, aiming for the officer.

"No." the hooded guy yelled as she let the arrow go, knocking the gun out of the officers hand before she turned and ran for the fire escape. She glanced back to see him pick up her arrow before she pulled herself up onto the rooftop and took off.

She wasn't about to reveal who she was just yet, not until she knew more.
