'You have a twin?' Stiles gaped. 'I'm sorry. That came out wrong. You have a twin!'

'Scott, how could you not tell me this? You don't keep stuff like this from your best friend!'

'Or your pack.' Lydia butted in.

'Scott.' Stiles snapped his fingers in front of his face. Scott's eyes were trained on me. I smirked as I walked up to them.

'In his defence, he didn't know I existed.' I smirked.

'Who the hell are you?' Malia growled.

'Put away the claws kitty.' I rolled my eyes. They all exchanged a confused look, trying to figure out if there was some hidden meaning to that phrase and I actually knew something.

It was fun to watch them second guess themselves.

'Why are you here? And what do you want?' Lydia asked.

'And how do we know you're not just a cheap liar?' Stiles asked.

'You don't.' I shrugged. 'But I'm not here for you guys. Well in a way I guess I am. I need your help.'

'Why would we help you?' Scott asked.

'Because if you don't, a lot of people are gonna get hurt.' I replied.

'What? What do you mean by that?' Stiles frowned.

'Would you look at the time!' I exclaimed. 'I have to get to class.'

'But the bell hasn't even rung yet.' Malia said. As if on cue, the bell rang. I smirked and walked away.

'It has now.' I called over my shoulder.

The rest of school was ultimately boring. I knew when Scott briefed Mason and Liam. I caught them trying to get a good look at me. I waved and smiled at them. Rookies.

I was dreading going... to the McCall house. I honestly didn't want to do the whole family reunion thing. No matter how it goes, I know I'm still gonna hate it. Especially if they do the whole emotional I-missed-seeing-my-daughter/sister-grow-up thing. I just might puke if they do that.

I took the long way and drove to the house as slowly as possible. I'm pretty sure I would've gotten there faster if I walked. McCall Senior said he'd get Melissa and Scott home so he could break the news to them. You know, ease them into it. But I beat him to Scott.

I sighed deeply when I finally pulled up at the house. I hopped out of my car and walked up to the door. I winced. From the screaming match going on in there, the whole easing-them-into-it thing didn't seem to be working too well for Mr McCall.

'How do I know these DNA test results aren't fake? And how did you even get my DNA sample?' A woman, Melissa I'm guessing, yelled.

'I would never lie about something this serious. And I lived here when I was in town the last time. Getting my hands on your hair brush wasn't that hard.' Mr McCall replied.

'Why didn't you tell me as soon as you found out!' Melissa screamed. I think she threw her shoe at him.

'She was in a coma! What were you gonna do for her while she was in a coma? Besides, I wasn't sure. It's just recently I had the DNA test done.' He replied.

'You weren't sure?' She asked incredulously. 'What do you mean you weren't sure! You knew the exact moment you saw her. She looks exactly like my grandmother!'

I think she threw something at him again because I heard glass shatter. Probably a vase. The poor guy is dying out there. Is it unfeeling of me to find this a little funny? The big bad FBI brought to his knees by enraged ex-wife. This is comedy gold people.

'You were always a douche. But now you're a...' I snickered at that one.

'She's here.' Scott announced. 'I think she has been for a while now.'

Damn him and his wolf hearing. My stomach was suddenly full of butterflies. I didn't really let myself think about this before because I didn't want to build up hopes just to have them crushed. This kind of life... with family and friends... and people who care about you must be nice and I may wish for it sometimes when I'm indulging in a self pity party but I know it's not for me. Some people are just not made for it. Anyone who cares about me is putting themselves in real danger and I'm not going to let anyone do that for me.

I have to go in there and make them hate me. I'm only here because I couldn't talk my way out of it. I can't get distracted or sentimental or attached. I have to do this. For them.

I steeled myself, took a deep breath and walked in.

'Hello.'
Melissa took one look at me before bursting into tears. Mr McCall tensed. Scott was leaning against the wall, regarding me with watchful eyes.

'My baby.' Melissa rushed forward and wrapped her arms around me. I stiffened. My eyes widened.

'Melissa, maybe you should give her some space.' Mr McCall suggested. She pulled back and cupped my face, staring into my eyes before she stepped back. I frowned.

'I'm sorry.' She said to me. Damn it! The sharp words on the tip of my tongue melted away. She looked like a three-year old whose lollipop was just stolen. I can't kick her when she's already down.

When did I develop a heart? Ugh.

'Melissa,' Mr McCall started.

She glared at him. 'Shut up. Just shut up and get out of my house!'

'I know you really don't want to see me right now but you can't just kick me out. I'm her father.' He said.

'Actually,' I interjected. I can kick him down. 'You're not my father. You're just a sperm donor.'

He glanced at Scott who was grinning, then at me. 'You two really are twins.'

I frowned and shot Scott a questioning look.

'I said that to him too once before.'

'Oh. Well I'm pretty sure you didn't say this.' I said. 'And no offense to you Melissa but you're not my mother either. I've never had one and I probably never will. You know nothing about me and I know nothing about you. Any of you! Sure you carried me in your stomach for nine months but for all I know I could have been born in a lab. The only thing I have in common with any of you in this room is DNA. So kindly save the family drama and don't pretend like you know me or you get me because you don't and you never will. And I will be going back to my old life as soon as possible.'

Too harsh? Maybe but that's the point.

'You really want to go back into the system?' Mr McCall raised an eyebrow. Melissa is right. He really is a douche.

'It's been more family to me than you have ever been or ever will be.' I replied.

I turned to Scott. 'My room please?'

'Upstairs last door on the left.' I nodded. I'll get my bags from the car later. Preferably when they are all gone.

I sat down on my bed and listened as Mr McCall explained my experiences in my previous foster homes to them. All the massacres, abuse and so called "animal attacks". The official reports were pretty bad but in the end, it didn't even come close to the real thing.

I got tired of listening so I curled on my side and plugged in my earpiece.

I stayed up in my room till dinner. Melissa eventually had to leave for work. She's a nurse at Beacon Memorial. I think that's the name of the hospital. With the amount of dead bodies that have been there, it definitely should be.

***

'Stiles!' Scott yelled exasperated. His pack came over a little after Melissa left and he briefed them about me. They still haven't left. I can hear them downstairs. God, I hate being the topic of discussion. It's so annoying.

I wasn't planning on going downstairs. At all. Or even so much as stepping out of my room. Until my stomach started rumbling nonstop. I had to order pizza. I've learned to eat whenever I can because in my life, a next meal is never certain.

The doorbell rang. Well that's my cue.

'What's for dinner?' I asked as I trudged downstairs. They were all gaping at me.

'Spaghetti.' Scott replied when he finally got himself together.
Good thing I already ordered pizza.

'Close your mouth Stiles. Or you'll catch a fly.' I rolled my eyes and pulled the door opened.

'Is that her? She's hot.' I heard Liam whisper followed by a smack sound. Hayden probably slapped his head.

'Here's your pizza. That'll be $12.45.' The cute delivery guy said. Yummy. The pizza. Not the idiot. I am starving.

'Thanks. You're a lifesaver.' I pecked his cheek and handed him the money. He blushed furiously. I rolled my eyes. Teenage boys and their pheromones.

'Well, bye.' I slammed the door in his face. Teenage girls and our mood swings. I love us.

I set the pizza down on the centre table. I grabbed a slice and brought it to my lips. I could feel their eyes following my every action. I sighed and set it down.

I glanced at them. 'What?' I snapped.

Scott, Stiles, Liam, Mason and Hayden had the decency to pretend they weren't staring. Lydia brushed off some invisible dirt from her nail while Malia just kept on staring at me. It's understandable that her manners are a little rusty. I mean she did spend half her life as a wild animal. Literally.

I raised an eyebrow. 'Never seen a girl eat pizza before?'

'Well I'm leaving. Don't call me unless you have something real.' Lydia huffed. She picked up her bag and dragged Malia with her to the door.

'Hayden, I promised your sister I'd drive you home. We all have school tomorrow. Go to bed and stop stressing yourself over something that may be nothing.' Lydia said.

'Bye.' Hayden kissed Liam goodnight.
Young love. So... disturbing.

Eventually they all left. Only Stiles stayed. Apparently he doesn't trust me. What does he think I'm going to do? Murder the family in the middle of the night? Talk about paranoia.

I picked up the pizza only to discover that I'd lost my appetite. That night, I cried myself to sleep. I guess hearing Mr McCall recount all my past experiences hit me harder than I thought. I couldn't stop remembering every death. Everyone that got hurt because of me.

***

Whatever was going happen, was going to happen tonight because it's a full moon. I had the when, I just had to figure out the where. It was proving a lot harder than I thought. It's going be somewhere with lots of people. I just have to find out what big event is happening tonight.

So I figured I'd do what most girls do when we need to find out something. Flirtatiously ask a hormones riddled guy. Though I kept the flirtation to a minimum. The guy wasn't exactly encouraging.

'What's your name?' I tried to smile. Keyword being "tried".

'Jared.' He mumbled. He Iooked a little green. Just my luck.

He should just give me the information I need so I can get out of here. If this kid wants to puke, fine, but he better not do it on my new peach coloured pumps.

'So what's going on tonight?' I smiled. It's probably a bad strategy to ask a kid who looks like the school's outcast but what can a girl do? It's the best I've got. Especially since I don't want to ask Scott personally. That's going to raise suspicions, he'll want to find out what's going on and I want to keep him out of this mess.

'Wh-wh-what?' He stuttered. God, give me patience.

'Is there's anything important happening tonight that a lot of people are going to go to?' I asked slowly.

'Well there's the lacrosse game.'

'Lacrosse game? What the hell is lacrosse?' I frowned. He turned greener.

'You know what? Forget it. I'll find out on my own. You look like you could use a bucket.' I backed away.

Three.

Two.

One.

Vomit.

I wrinkled my nose and walked away. At least I saved my pumps even though I can't unsee that.

'Hi. You must be...' I said to the random person passing by me.

'Sydney.' She replied. 'You're the new girl.'

I need your help and that's the only reason I'm going to let you get away with that.

I pasted my nicest smile on.
'Sydney. Yeah. I'm Casey. You're in some of my classes.'
I have never seen you before.

'Yes.' She smiled. 'We have History together.'
Well, good or else that wouldn't have gone well.

'I heard there's a lacrosse game tonight.' I said.

'Yes. Almost everyone attends the games. Scott McCall is captain of the lacrosse team.' She replied eagerly.

Oh Scotty boy.
Now I just have to figure out what the hell lacrosse is.

I decided to ask Sydney rather than go through the boring process of looking it up.

'Tell me a little about the game.' I said.

'Well it's a pretty violent game.'

'Violent?' I echoed.

'Yeah. Really violent actually. Not like boxing violent but still violent.'

'Of course it's violent.' I muttered under my breath.
Why couldn't they play something like tennis or croquet. Something that's not violent and doesn't involve personal contact.

'But in the end its kind of like soccer. Or hockey. There's a ball and a net and lacrosse sticks.' Sydney added.
Of course there are sticks. What else would they whack themselves with?

My mind was already working double time, trying to process the new information.
So they may show sometime during or after the game. So now I have the where. I just need the who.

I already started walking away when it crossed my mind, 'Who are they playing?'

'Uh... some prep school. I think. I don't really remember. But they're not from around here. The school is an out of town school but they set it up. Apparently they really wanted to play Beacon Hills.'

'Oh.'

'No, wait. I remember now. Sorry. They are a private team. Their coach set it up. Which is weird because our team is inconsistent. Sometimes they are good and sometimes they suck. So why would a private team want to play them?'

'Crap.' I muttered under my breath. And there goes my who.

I marched off in search of Scott. There's no keeping them out of it now. I can't protect them while they are on the pitch. Or field... I really need to look up this lacrosse thing.

I wasn't able to meet up with Scott till a few hours after school. I had detention. Apparently I shouldn't threaten people who stare at me creepily. Especially not when they are teachers.

When I eventually caught up with Scott, he was with Stiles and Liam on the lacrosse field. I've done my homework. It's field not pitch.

'Scott, you have to get this game cancelled. I don't care what you do, you have to.' I said. Stiles and Liam frowned. I ignored them both.

'Is that how they say hey where you're from? Hey back.' Stiles said.

'Cute.' I glared at him.

'Why do you want to get the game cancelled?' Scott asked.

'Plenty reasons. None of which I'm going to disclose.' I replied.

'I can't help you.' He said simply. Stiles grinned smugly.

'Look, this is serious okay? If this game holds, people are going to get hurt. A lot of people.' I said. My tone conveyed the urgency.

'I don't know if you've noticed but this is lacrosse. It's a pretty violent game. Hurting people is the third most important goal of the game.' Stiles said. It was hard to tell whether he was smirking or grinning. But with a name like Stilinski, I guess it is to be expected. Scott and Liam frowned.

'Third?' Scott asked with a confused expression that girls probably thought was adorable. It irked me.

'Yes.' Stiles replied.

'Why third?' Liam asked. I guess he could pass for cute.

'Well scoring comes first. Preventing the other team from scoring comes second. And then hurting people, third.' He counted it off on his fingers. I rolled my eyes to heaven and back.

Did he escape from a mental institution?

'Focus!' I snapped. 'This is serious. Doesn't it seem strange that a private team is coming to play you guys? A private team! You guys aren't exactly the best team in the league.'

'Actually that is strange.' Scott frowned.

'Of course it is.' I refrained from adding the "duh" but it was loudly implied.

'Look those people. The other team. They are not normal. They are stronger..., faster than any normal...'

'We can handle it.' Liam grinned. My irritation level spiralled.

'No! You can't! You're not listening to me. These people, they will crush you. You don't stand a chance against them.' I scowled.

'I think we'll do just fine.' Stiles replied, patting Scott's chest. Slapping it actually. I gritted my teeth, trying to control my frustration.

'There are a lot of things out there that are scarier than a True Alpha and his dysfunctional pack. You should consider that before you put your pack in danger.' I said darkly. Their mouths were hanging open in shock.

'You may stand a chance against them but don't think the rest of your pack will. So when they kill these two doofuses over here and the glitter triplets, just remember, I warned you.' I said to Scott.

The first one to find his voice was Stiles. 'Glitter triplets?'

They followed my gaze to where Lydia, Malia and Hayden were sitting on the bleachers in matching sparkly shirts even though they all wore it differently. I don't know if it was a stupid plan or just an unfortunate coincidence. Though if I had to pick one, Lydia wore it better.

They were staring down at us with worried expressions. Well, looks like Malia and Hayden were listening in. And from the looks of it, they've already filled Lydia in.

I smirked and waved at the girls.

'Oh, glitter triplets.' Stiles echoed. I rolled my eyes and shouldered past him. I walked onto the field.
If I can't stop the game, then I'm playing in it. I could feel their eyes on me. I don't think they've gotten over the shock just yet.

'Coach!' I yelled.

'What is she doing?' I heard Stiles say behind me.

'Coach, I wanna play lacrosse.' I stated. Coach Finstock glanced at me before bursting into laughter.

'And I want to be relaxing in a five star resort not coaching a bunch of lazy idiots! Why don't you go try out for cheerleading.' He suggested.
I picked up a lacrosse stick and the ball. I grinned before I sent it hurling into the goal despite the two goalkeepers there. Coach slowly put down his clipboard.

'Let me rephrase that, I'm gonna play lacrosse.'

'Anybody see that! That is how you play lacrosse! That is how it is done! And that is our new lacrosse player! Come here, kid. What's your name?' He yelled.

'Casey.' I grinned. I looked over my shoulder to see Stiles with his mouth hanging open. He sure seems to do that a lot. I wonder how many flies he catches a year. Malia on the other hand, looked annoyed.

'I want you on my team. First line. Come on let's see how you do as the goalie.' Coach grinned. 'Somebody get this girl some gear! Not you Greenburg! Sit down.'

I caught every single ball much to Scott, Liam and Stiles' annoyance. Apparently Liam and Scott used to be the best players on the team. Did I mention that Stiles sucks at this? He has to be one of the worst players on the team. Seriously.

After coach made me play every position in the game, he finally called off practice. He told us to grab something to eat and freshen up for the game.

I wasn't exactly surprised when Scott and the whole gang showed up in the girls locker room looking for me.

'You know, you should have knocked. I could have been naked.' I said when they walked in. My back was to them.

'You can't play in the game.' Scott stated.

'Why not?' I feigned ignorance. 'Fine Rock said I could.' They all stared at me confused, for a second before understanding dawned on Stilinski's features.

'It's Finstock. Coach Finstock.' He corrected.

'Oh. I prefer Fine Rock.' I replied.

'It's Finstock! Fin-stock. With an s and a t.' He replied vehemently.

'Stiles, I truly honestly don't care.'

'Oh. Well.' He ran a hand through his hair and gestured for Scott to take over. Someone else beat Scott to it though.

'Who the hell are you? And why do you know so much about us?' Malia said.

I bite back my grin before I turned to face them. Is it wrong to have a little fun and rile them up? I am going to save their lives after all. The least they can do is entertain me.

'Oh, coyotes. Ever so bold and... arrogant. Mangy animals if you ask me.' I raised an eyebrow. She growled and advanced forward.

Stiles caught her arm. 'Malia, wait. She's trying to get to you. What do you want?'
He directed the last part to me.

Maybe if I rile them up enough they maybe too mad to play in the game.

'So the mental institution escapee who was once possessed is questioning me? How cute.' That's right people. I did my homework and I did it well. And I'm not talking about the lacrosse thing. I didn't waltz into Beacon Hills blind. I did my research before coming here.

'Quite a pack you've got here Scott. Correct me if I'm wrong but you have all tried to kill each other at some point or the other.' I grinned. Scott clenched his fists. 'Tragic.'

'Your beta tried to kill you and steal your power so he could save a girl who was working for a guy who broke you guys up. And your best friend tried to kill you all when he was possessed by an evil spirit. Mason here was a psychotic werewolf who almost tore apart the entire town. And Lydia, the banshee, tried to poison everyone at her birthday party.' I gestured to each of them. Liam growled lowly.

'Wow, you definitely not in the running for pack of the year.' I chuckled. 'But trust me, if there was an award for worst pack on the face of the earth, you guys are definitely it.'
All is fair in fun and entertainment.

'I know what you're trying to do. It's not going to work.' Scott said.

'You sure? Mangy mutt over there looks just about ready to claw my eyes out.' I smirked. I was talking to Liam because I was focusing on those who were playing but Malia thought I was talking to her because I already called coyotes mangy. She bared her teeth. I rolled my eyes.

'Lets get out of here.' Stiles urged them.

'She's trying to get to you guys and whether you admit it or not, she is doing a good job of it. So move it people. Go cool off. She's wants you to be too mad to play.' Stiles said.

To say I was shocked would have been a huge understatement. I guess I underestimated him. Maybe he's not brain dead after all.

***

I figured out the two... mercenaries while the game was still on. I knew they knew that I knew who they were. But it didn't make sense. It was almost like they wanted me to know which was slightly terrifying because it felt like I wasn't seeing the whole board, just what they wanted me to see. It was like everything was going according to plan. Their plan. And that didn't sit well with me.

They didn't attack during the game. It ran smoothly. We won but it was kind of like that's what they wanted. Mild paranoia was really starting to set in. Except nothing happened. After the game, they.... just left. I watched them get on bus.

Even Scott noticed that something was wrong because... nothing went wrong. I couldn't shake the uneasy feeling even as I changed out of my lacrosse gear and by the time I got to the parking lot I knew why.

The two guys were standing in the middle of the lot. Stiles was knocked out on the floor clutching a metal baseball bat. Lydia was also unconscious. Mason was hiding between my car and Stiles' crappy jeep. Is that thing even road worthy?

Malia and Scott were fighting and loosing against the two guys who didn't even look like they were putting their all in it. Adrenaline shot through my system.

I grabbed a lacrosse stick sticking out of a gym bag one the floor. Whoever this belongs to, I hope you're not attached to it because the chances of you being able to use it again are slim to none.

By the time I got to them, Malia was laying unconscious on the floor. Great.

I went after the one standing over Malia's unconscious body while the other one repeatedly hit Scott on the floor. I sighed.
I warned him.

I broke the lacrosse stick on my knee and threw the sharp end at Scott's attacker. Like I said, the chances of the lacrosse stick surviving is slim to none. It went through him. He hissed in pain and threw a weak Scott aside before slowly pulling the lacrosse stick out of him.

He advanced towards me. I tried fighting both of them off but it was proving hard to do seeing as there was two of them and I only had one short weapon.

Scott's attacker gripped my hands while his friend took a swipe at me with his blade. He winced in pain as the injury that should've been in me appeared on his skin instead.

I used that opportunity to free my hands and steal his blade.

'I'm the Girl with the eyes of Steel. Didn't they warn you?' I smirked, before slashing the other one through the stomach. He fell to his knees and howled in pain just as a tall black figure materialized. All the lights went out.

I gulped and tried to tamp down the huge rush of fear that shot through me. He has never come. He doesn't come. Only in the nightmares. Never in real life. I took an involuntary step backwards as he advanced forward purposefully. The urge to run filled my system but I couldn't leave. I couldn't leave them behind. Not like this. Defeated and defenceless so I stayed rooted to the spot.

I gripped the blade tighter and swung at him when he was within arms length even though I knew it was useless. Darkness grabbed my hand and squeezed hard until the blade fell out. He had no features. No face. Everything was black. And cold.

He grabbed my neck and squeezed, cutting off my air. I gasped and struggled against him till I couldn't anymore. I watched in horror as a single pitch black claw reached out to touch my forehead. The last thing I saw before my world exploded was a black manic smile.

***

'Is she gonna be okay?' Voices floated around me. They sounded far away. My mind felt like it was covered with a large thick blanket.

'She saved all our collective asses.' A somewhat familiar voice said.

'Well I don't know what to diagnose her with. Whatever I give her may have an opposite effect. We don't for a fact that she is like any of you. We can only wait and hope she wakes up. In the mean time, I would perform some minor invasive experiments to confirm or retract Mason's discovery.' A different calmer voice said.

What are they talking about?

'Woah. Woah. Wait! What are doing? You're gonna cut her?'

'No.' The calm voice replied. I heard a sigh of relief followed by, 'Scott is.'

'What? Why me?' The voices were getting closer.

'Why is cutting her up even on the table!' The previous voice yelled. The other voices seemed to ignore this.

'Well if what Mason says is true, you heal fast.' The calm voice replied.

There was a tense silent pause.

'Fine. I'll do it.'
I felt a cool soothing metallic touch on my arm.

'I think you'll need a bigger blade.' A voice piped.

'Ahhh! Ouch.'

'Incredible. It's like she can't be hurt by metal.' The calm voice said. 'Instead the wound somehow manifests itself on the perpetrator.'

'I'm not sure I want to be here. The last time this happened and Stiles said that, we were stung by a psychotic night terror-ed chimera.' A new voice said. It was really close. My mind felt a lot less foggy and clouded.

'Malia has a point.' A different voice said.

I slowly fisted my hand before opening my eyes. There were three men and two girls. Sorry, make that one man and two boys. They all had their backs to me.

I sat up and they all turned. Before either of them react, I grabbed the pale weak looking one with the buzz cut and threw him on floor. I positioned my heels clad feet at his throat.

'Any sudden movements and I will crush his throat.' I threatened.

'Stiles!' The other guy yelled. The others took a step back.

Styles? I'm about to kill a person and he's thinking about fashion? Seriously?

'You have ten seconds to give me a good reason why I shouldn't kill him.' I said calmly but I lowered my heel for good measure.

'Guys, help.' The guy on the floor said. I increased the pressure against his throat.

'Casey!' The other guy said firmly.

'Who the hell is Casey?' I asked.

'Uh oh.' The strawberry blonde shook head.

****

Yay! Memory loss.

Poor Casey. I hope she doesn't kill Stiles! Just in case you don't know yet, this is a Stiles-teen wolf fanfic and it is not going to make sense if you haven't watched the movie to season 5 after they defeated the Beast of Gevaudan. I think it's season 5 but I'm not too sure.

I just realized I didn't put a disclaimer on here.

Disclaimer! I do not own teen wolf! Even though I really wish I did.
