DISCLAIMER: I do not own any of the characters mentioned in this story, apart from the character of Megan. However, the plot line is mine

Elena stood in complete shock. Her soft brown eyes were staring at Klaus and Megan. Her whole body froze and tensed. It couldn't be.

Slowly coming back to reality, Elena began to frown. She compared the two faces; the same piercing blue eyes, the same strong nose, the same fair skin.

"Hello brother" Elena knew she had heard the same British accent somewhere before.

"I thought you died Megan. I thought the wolves had finally finished you off"

"So did I" Megan was smirking now, staring at her brother with a look of complete hatred. "I mean, you did leave me there, didn't you? Your own little sister?"

"I think we both know it wasn't like that Megan. It was either you, or all of us. I chose to save the entire family."

"Oh, how noble. Tell me Niklaus, where's mother these days? Or Finn? What about Mikael? Even your darling Rebekah has abandoned you for a human boy?"

Klaus growled, his growing rage causing his entire body to shake. Elena cautiously took a step forward, placing a hand on Klaus' shoulder to calm him down.

"Klaus, don't listen to her. Yes, you've done some bad things in the past, but your actions now can change that. She only wants a reaction out of you. Don't give her what she wants."

Megan snorted, and turned to face Elena.

"Ha. The ever-faithful Elena Gilbert. Don't think I haven't been watching you too. I was curious as to what everyone's obsession with you was. I mean, look at you, you're not exactly anything special."

Suddenly, a wave of feelings came over Elena. Ignoring her previous words with Klaus, Elena stepped forward and raised her hand. With all of her might, she slapped Megan across the face, but only managed to cause her to smirk even more.

"Be careful who you make an enemy out of Elena. You may think you've experienced terrible things in the past, but that is nothing compared to what could happen to you." Megan's eyes narrowed, and Elena gasped as she saw her eyes darken. Suddenly, Elena shrieked, and fell to the floor. Pain spread through her body, causing her to writhe on the floor. Once again, Megan smirked, and with a flash of golden blonde hair, she had disappeared.

Elena sat on the floor, catching her breath, until a familiar pair of strong arms wrapped around her. She breathed in his scent, feeling instantly relaxed.

"What the hell is going on here?" Damon said, his accusing eyes staring at Klaus.

An hour later, Damon, Klaus, Caroline and Elena were sat in front of the fire at the boarding house. Damon was pouring out yet another glass of Bourbon, and he was watching Elena warily, in the fear that she might break down. After Klaus had finished explaining the events of that morning, there was a moment of silence throughout the room.

"So, what your telling me is, that you have another sister?" Damon said finally, hesitantly taking his eyes off Elena to question Klaus.

"Unfortunately yes. But we thought she had died. She was turned by our mother, and she decided to go into town one night. What she didn't realise was that it was a full moon, and almost every villager was transforming into a werewolf. That night, she stumbled home, covered in sweat. She had been bitten by a werewolf. We all sat by her bedside until she had gone. There was only one way of saving her, but we were already defending the house from the werewolves, so we had to let her die. She was much younger than the rest of us, only 14, so she wasn't as strong. She didn't survive the night." Klaus looked down, an obvious feeling of regret washing over him.

"How is she back here now?"

"We thought it was impossible, but there is only one explanation for her return. My mother wasn't faithful, as you could tell from my birth. She became pregnant yet again, and once more the child did not belong to Mikael. Megan's father was another witch, however he was one of the strongest at this time. With both a mother and father having powers, we were always protective of her, knowing that if she had the gene then she would be extremely powerful. But, as she grew up, there was no sign of any power. Still, we all became attached to her, and we all loved her dearly. Her death was a shock to us, and we all regretted it instantly."

"So, your mother still wanted to protect her when you originally found out about the werewolves?" Elena asked shyly.

"Yes. With no sign of any powers, mother decided to turn her at the same time she turned the rest of us. But, she was much younger, so she was the weakest sibling. There is only one way that Megan could have returned, and as impossible as it may seem, it is the only explanation. Her powers must have finally turned on."
Elena sat there in shock, realising what Klaus was suggestion.

"Wait, that means…"

"Yes. My sister is a Vampire-Witch hybrid. And a powerful one."

Chapter 2 finally arrived! And another shocking one at that! I apologise for any mistakes, this is my first fanfiction, so I'm not quite used to it yet. And comments and reviews would be much appreciated!

Just to let you guys know, the next few chapters may take a little while to put up. I'm currently in the middle of my exams, so I need to concentrate on them more. But in a couple of weeks I will start to add to my storyline more regularly!
