This is my first fanfic, hope you enjoy!

Chapter 1

Elena walked home shivering, with the breeze whipping her blond hair wildly around her face. It was cold, of course it was cold, it was nighttime. But Elena thought she felt something...something weird about it, almost as if it was not natural. The wind picked up, throwing leaves in her sight, and suddenly she saw a figure in front of her. She looked very familiar, although Elena had never seen her before. Blond hair, blue eyes...

"Oh my gosh,"Elena whispered.

No, it was impossible, it can't be. Elena screamed, just before she was knocked out.

Elena opened her eyes and looked around. What is this place?, she thought, taking in the stone walls of the huge room. She noticed that her head was hurting as though someone had hit her. She was sitting on the ground, with her hands and waist tied to one of the many poles that were used to hold the ceiling up. Her feet were also bound together in front of her.

Wait, Elena remembered, someone had hit her, it was-

"Katherine," Elena said, seeing the pale girl that looked like her.

"Hello Elena," Katherine said. "I knew you'd recognize me. It was Stefan who told you about me, isn't it?"

"You're not dead. You were alive this whole time," Elena said.

Katherine laughed. "Yes. They were stupid to think I actually died. I thought of telling them what really happened the day they thought I burned in the sun, but I have a better idea."

"What's that?" said Elena, fearing for what Katherine had to say next, but curious at the same time.

"To impersonate you, then take my revenge on them," said Katherine.

Elena had never heard a more crazier idea, but she had to admit that it was brilliant. Only, there was one flaw.

"They will know," said Elena. "They'll know there is something wrong. You don't even know how my life is like, and who my friends are, and-"

"Which is why I will read into your mind," said Katherine, showing Elena her fangs. Then Elena felt two stings on her neck, feeling Katherine looking into her.

KPOV (Katherine's Point Of View)

Katherine had made it through school without anyone noticing anything suspicious. At the end of school, she sensed someone reaching out to tap her on the shoulder. Stefan.

Katherine turned, and pretended to look surprised. "Stefan!"

"You look like you're hiding something," said Stefan, glancing at her. When she said nothing, he said, "Joking. Let's go to the boarding house."

Katherine nodded. She had missed Stefan, and his vibrant green eyes that had always brought life into her. She loved him. But that was all before, she reminded herself, I have a mission.

At the boarding house, Katherine sat on the bed and looked around, recognizing the gold coins back from the Italian Renaissance. She also recognized a photo of herself in a blue gown that matched her eyes. She picked it up, and noticed Stefan staring at it too.

Katherine put it down, and searched his face for any signs of pain and misery, but he kept his face composed.

"Do you miss her, Stefan?" Katherine whispered.

At first, he said nothing, then, "You know I only love you, Elena."

Anger started up inside Katherine, hating the girl who shared the same appearance as her.

"But you miss her, right?" said Katherine loudly. "Don't you still love her?"

Suddenly, she felt tears come out of her eyes. Without thinking, she ran out of his room crying, just like how she had when Stefan and Damon had told her that she can't have them both.

"Elena!" Stefan called after her, but she kept on going, hating him as much as she hated Elena.
