Chapter One

Hey, guys! Thanks for checking out my story. You probably already know that I do not own TVD (shocker, I know). This story is based on season three of the vampire diaries, but I have put my own spin on it. This chapter is based off of TVD episode Dangerous Liaisons. I hope you like it and feel free to favorite and follow my story and comment on it to tell me what you think. :)

I received an invitation to the Mikaelson ball that the original vampires were hosting, but it wasn't because I was a Gilbert or Elena's little sister. Sure, I was related to the doppelganger but that had nothing to do with it.

I had one of the last white oak stakes hidden carefully under my maroon colored dress. Esther Mikaelson wanted me to use it to kill her son, Klaus after she links him and his siblings together with a potion.

I knew why she wanted her children dead, but I was a little confused about why she would want me to do it. I was your average teenage girl, human, and weak compared to the original vampires.

Which was why my palms started to sweat as I entered the large Mikaelson mansion. It was very nice and modern; a lot of work had been put into the architecture and design. After all, Niklaus had to make it a home fit for an original and his hybrids. I tried to think about this and not the fact that there was a white oak stake poking into my backside but otherwise out of sight.

If Niklaus found out about this, I was one dead teenage girl. Esther reassured me that Niklaus would not hurt me, and I believed her because after all, if Klaus caught me, he would find out about his mother's plan and kill both her and I.

No, Esther would make sure that we would both end up okay. In exchange if everything went successfully and the originals were dead by tonight, then Esther would bring back Jeremy, Elena, and I's parents. Also, Elena's blood would no long be used to sire any more hybrids, and we could start to live a normal life again.

"Mary, are you alright?" Caroline Forbes asked me. She was standing behind me wearing a beautiful blue dress and jewelry that the hybrid had given her. Everybody knew that Klaus had a thing for the blond vamp.

I frowned. If my plan was successful, then Caroline would die tonight since every vampire was linked to one of the originals. I didn't want Caroline to die; when she used to hang out with Elena when we were younger, she didn't treat me like a little kid even though I was younger than them. Unlike the others, she didn't shoo me away. She used to braid my hair and ask me about any cute boys I liked and how I was doing in school.

But if I had to choose between her and the greater good...

"I'm fine," I lied as I straightened out the front of my long dress.

Two guys from inside wearing formal suits held open the doors for us as they ushered us inside. Already, there were people gathered around in the large room that had been cleared out for guests.

I could see people making polite conversation as they drank expensive champagne. There was music playing in the background, but nobody was really dancing to it yet. It sounded like some kind of classical music from another century.

"Wow," Caroline and I said at the same time as we took in the large area, high ceilings, and grand wooden staircase. My house was nice since my dad was a doctor before he died, but it was nothing like this. The Mikaelsons had a lot of money.

I could see Damon and Stefan hanging out with Sheriff Forbes and Carol Lockwood and some of the others. The Salvatores didn't know it yet, but Elena would be coming to this event against their wishes. Even though I didn't like the sound of it, Esther needed the doppelganger's blood to link the originals.

As Caroline and I continued making our way inside of the room, a man looked around the room until his eyes landed on me. Something in his eyes softened as he made his way towards me. I was taken away both by his handsome looks and odd behavior. He was tall and on the leaner side with mischievous brown eyes that pinned me to the spot and messy light brown hair that I couldn't help but imagine running my hands through.

I usually didn't find strangers that attractive.

"Hello, love," he said now standing right in front of me. Something in his eyes twinkled as he sized me up, seeming to like what he saw. I wasn't Elena Gilbert who could make two guys love her all at once, but I wasn't ugly.

"I don't believe I've seen you before," he said smiling. "I'm Kol Mikaelson."

He gently grabbed my hand and kissed it lightly, making me feel sparks. My heart pounded hard in my chest as I comprehended his words. He was one of the original vampires that I would be trying to kill tonight.

I opened my mouth, knowing that I should say something right now if only to relieve the awkward tension but nothing came out. My mouth stayed open as my mind went blank. What if he found out about the white oak stake under my dress?

Kol chuckled, looking amused. "You don't have to worry, love, I don't bite," he promised.

"You say that now, but I've heard differently," I finally managed to say. I figured that if I made talked to him nicely, he would go away. Why was he talking to me in the first place?

Kol laughed, loudly, disrupting others around us in the process. "For a moment there, I thought that you were speechless in my presence," he joked.

"I was not," I defended myself even though deep down, I knew that he was right.

"I hope it wasn't because you are afraid of me." Kol frowned. I didn't have time to wonder why he seemed upset at me fearing him. I must be reading him the wrong way. He probably takes pleasure in me being scared. I've heard rumors about him being just as evil and violent as his brother, Klaus.

I scanned the room to see where some of the others were.

Caroline had found Klaus, and they were dancing together. Even though I had not met any of the originals before, I knew that he was Klaus because his mother had showed me a picture of him so that I would know who to kill. He had curly dirty blond hair and stunning blue green eyes that held a strong intensity behind them, indicating that he was strong and had seen a lot during his time on Earth.

He looked just as handsome in a black and white suit as his brother did, and he seemed to be in a deep conversation with Caroline as he spun her around. I averted my gaze before he noticed me.

My hands shook a little, but it was only natural to be nervous in situation like this.

"Who were you looking at?" Kol asked me.

"Nobody," I shrugged my shoulders.

He looked at me for a moment as if he didn't believe me but otherwise let it go.

For the first time, Stefan and Damon noticed me with Kol. They were like two overprotective brothers. They both loved my sister which was why they felt like they needed to watch out for me.

They started to storm over to Kol and I before they were interrupted by the front doors opening and Elena making her grand entrance. She wore a beautiful, black gown and her hair was twisted elegantly to one side.

They both stopped moving when they saw her. It was clear that Elena took their breath away. But I couldn't help noticing Stefan's slight disapproval and Damon's anger. They both didn't want her coming here since they deemed it unsafe.

" I'm sorry, but we have been dancing this whole time, and I have yet to learn your name," Kol said, drawing my attention back to him.

"Mary Gilbert," I said, watching his face carefully. What would he think about me being related to Elena?

Kol laughed loudly. "Of course you are related to the doppelganger," he said, shaking his head.

Before I could ask him what he meant by that, a loud voice interrupted our chatter.

"If everybody could gather around please," a male voice said from the staircase.

Kol sighed. "That's my cue to leave, love, but I'll be back soon."

Then he disappeared. I turned around following his movements. He made his way over to where a girl with blond hair, Klaus, and two other unfamiliar men stood on the grand staircase. If I had to guess, I was starring at the original siblings, Klaus, Kol, Finn, Rebekah, and Elijah. I knew which one was Kol, the original hybrid, and Rebekah, but I couldn't tell whether or not the vampire who was starting to make a toast was Elijah or Finn.

"Welcome, thank you for joining us," the one with trustworthy brown eyes and a friendly smile said. "You know whenever my mother brings our family together like this, its tradition for us to commence the evening with a dance. Tonight's pick is a centuries old waltz, so if all of you could please find yourself a partner and join us in the ballroom."

By now, Esther had already made her way to her children's side. Her hair was a few shades darker than her daughter's, but lighter than Klaus' and it was styled perfectly. She was wearing an elegant black dress and heels. The original witch gave Elena a long look. It was sad how she was conspiring behind her kid's back to have them all killed, but I would do anything to have my parents back in my life again and alive. Ever since they died, our family had been broken, and I didn't see that changing anytime soon unless I did something about it.

I followed the crowd into the ballroom. Music started to play and everybody began to dance. Before Kol could make his way over to me again, Stefan found me.

"May I have this dance?" he asked.

I nodded and we began to sway back and forth. It was kind of weird dancing with my sister's sort of kind of boyfriend. He hadn't been the same since he left with Klaus and turned off his humanity switch. I wondered if he would ever be the same chivalrous gentlemen again. I hoped so; there weren't a lot of noble men like Stefan Salvatore out there.

"I thought that I should steal this dance with you before you have to suffer through another one with an original," Stefan explained.

"That was very kind of you," I replied.

Stefan's neutral expression didn't change. He wanted everybody to believe that he didn't care even though it was very obvious that he did.

"You know, you shouldn't beat yourself up over what you did," I said, referring to the fact that he murdered lots of innocent people because of Klaus and his compulsion. "You did it to save your brother."

In return for Stefan's loyalty, Klaus had given his blood to Damon to cure his werewolf bite. Talk about sacrificing for the people that you love. Stefan and I weren't that different.

If I didn't know any better, Stefan was fighting back tears.

Before he could say anything, the particular dance that we were doing required us to switch partners. Stefan now danced with Elena and me with Matt Donovan who had been Rebekah's date. He was nice enough, but we didn't have a lot to say to each other.

"May I step in?" the same man who had made the toast earlier on the staircase interrupted Matt and I as Elena made her way outside to talk to Stefan. She probably needed his help to convince Damon to let her speak to Esther.

"Uh, sure," Matt said slowly before walking away to find somebody else to hang out with.

Then I was dancing with another original vampire who I had yet to get to know.

"I don't believe that we have formally met before," he said with a charismatic smile on his face. Like Kol, he had some sort of similar European accent. "I'm Elijah."

"Mary," I introduced myself. "I'm Elena's younger sister."

"That would explain the resemblance," Elijah commented. "I hope that you have been enjoying the party so far," he added.

"Its been very nice," I answered.

"If there's anything that you need, please let me know," he said as everybody around us switched partners again.

"I do hope to see you around again sometime soon, Mary," Elijah said before walking away.

Honestly, I couldn't understand the original brothers interest in me. First, Kol had approached me and then Elijah. Did they mingle with all of their guests or did they somehow figure out their mother's plan and were now toying with me?

Once everybody was invited back into the main room and Esther had handed out the champagne spiked with her concoction that would bind the original vampires together, I knew that it was soon time for me to kill Klaus Mikaelson.

I was supposed to sneak up behind him and literally stab him in the back before he caught my scent. That meant that I would have to be quick, and I couldn't miss his heart. Esther would temporarily immobilize him with a spell while I did this, but somehow that didn't help me feel any less nervous.

I waited until Klaus left the room and headed down a long hallway before I shared a look with Esther. She nodded; she would be right behind me as soon as she could. I began to trail behind Klaus, making sure that nobody could see what I was doing. If anybody asked, I would say that I was looking for the bathroom.

I followed Klaus into what appeared to be a kitchen. My adrenaline was pumping by now as he opened up the fridge and dug around until he found a blood bag. "If it weren't for mother, I would be sinking my teeth into somebody's jugular by now," Klaus said. "I can hear your heartbeat you know."

I had already pulled the white oak stake out from under my dress and had it pointed at him.

Before I could process his words, he was growling viciously and zoomed over to where I was standing and slammed me against a bare wall. "What were you planning to do with that white oak stake?" he said, eyeing it in my hand.

I knew that I would be dead if it weren't for what happened next. Maybe Esther was banking on what would happen next, nobody will ever know, but it didn't turn out the way that she wanted. All I know was that for once in my life, I had been saved by a miracle.

Klaus squeezed my hand tightly until I dropped the stake and it hit the floor. I didn't realize until he met my eyes that I had been crying, how pathetic. Why did Esther think that this would work again?

He blinked as he looked into my grey eyes. His angry expression softened into one of regret until he was muttering something that I couldn't hear under his breath as he took a step away from me then stopped moving. While he was doing this, he looked at me in awe like I was his sole reason for existence. It was similar to the way Kol and Elijah had been looking at me, but I had only now realized it.

"After all these years..." Klaus slowly said. "Its you...you are actually real...my mate..."

He was in a state of disbelief.

"What are you talking about?" I asked, confused. What was a mate, and what did it have to do with this situation?

He took a step towards me and I shrieked as I shrank again the wall, thinking that he was going to try to hurt me after what I tried to do. "Please, don't hurt me!" I yelled as loud as I could, my voice sounding hoarse because of my tears.

A look of pain crossed Klaus' face as he sank onto his knees in front of me.

"I'm so sorry," he apologized. "I didn't mean to scare you. I would never hurt you."

I could tell by the genuine look on his face that he meant it. But why? Only minutes ago, I tried to kill him and his family before he attempted to stop me. What changed?

Before I could say anything else, Esther raced into the room. Klaus stood up onto his feet as his mother approached. She looked like she was in a hurry because she only had a few minutes to do this before her children grew suspicious.

"Do it now, Mary!" Esther exclaimed before chanting something under her breath. Klaus sank to his knees in pain as he clutched his head tightly. I took a step towards him before I hesitated. I didn't like seeing him in pain.

"Mary, hurry," Esther urged me as she clenched her jaw. "I can't keep him down for that much longer."

Klaus looked at me as I picked up the white oak stake off the floor and weighed it in my hands. He was still cowering in pain but something in his face changed. He gazed at me in a state of utter disbelief and betrayal.

I started to make my way towards him again with the stake as I pictured my mom and dad's faces. My dad's family were hunters. He would understand why I had to do this, and we could all be a family once more.

Before I could go through with the plan, Klaus stood up, straightening up his torso as he continued to shake a little but otherwise fight off the pain. He ran at vampire speed towards his mother and snapped her neck in a lightening fast motion.

Uh oh.

He took a few deep breaths before turning around to face me which gave me more time to process a couple of things. One, Esther Mikaelson was dead again, and two, I would be next.

"What should I do with you?"

What do you think is going to happen next? Did you like it? Why or why not? Until next time...
