The Doppelgänger's Sister

Part 1

Caroline sometimes wished that she was an only child. She sometimes really hated to be even related to her twin. She was sure sometimes that she was adopted, because she was so different from her sister. But what she really hated? To be the doppelgänger's sister.

Her parents sat her down when she and her sister were children and told her, not her sister but her, about people who would be after Elena. Their parents, Grayson and Miranda Gilbert told her a story about a vampire called Katherine Pierce and showed her a picture about her.

Katherine looked just like her sister but she just had clothes from different era. They told her that it was her job to keep Elena safe so she did her best to just do that. But sometimes it was really difficult, especially when she wasn't allowed to tell her about anything really unless one of the originals showed up.

"No," she told her twin.

"No? What do you mean no?" Elena yelled at her.

"I mean no," she told her simply.

"You're not the boss of me!"

"Baby sister," she liked to call Elena that mostly because it annoyed her.

"Don't call me that! I'm only few minutes younger than you!" It was almost always the same thing.

"You're not going," she announced to her sister.

"Like I said; you're not the boss of me!"

"Our parents..."she started to tell her sister once again.

"Yada, yada. I know, I know," she said, cutting me off.

"It's your job to keep your sister safe. Blaa blaa," Elena said, trying to imitate their late father. Their parents and little brother, Jeremy died in a car accident before the Salvatores moved into Mystic Falls. Caroline knew that they were vampires after Damon Salvatore tried to compel her (but luckily for her, she was wearing vervain) and she was trying to forbid her sister from dating Stefan Salvatore. She liked Stefan, but she was afraid of other vampires showing up. In the end she gave up, she just knew her sister would do whatever she wanted to.

"We're leaving," she declared to Elena after she was saved from a vampire called Rose. She really hated to put her life in hold again for Elena but she had to. Elena was only thing she had left really.

"What? Why?" Elena wondered aloud. She had no idea what was happening as Caroline started packing her stuff.

"We have to go. NOW, Elena!" She yelled.

"What's happening?"

"You said Elijah showed up and Damon staked him?" she asked her sister.

"Yes," Elena confirmed.

"Well... he's not dead...," she informed her twin, "... and if Elijah is here, Klaus will be too soon enough."

"Who the hell is Klaus?"

"Elijah's brother and they are after you, my darling twin."

"But why? Because I'm the doppelgänger?"

"Exactly," she said and started to tell the story her parents once told her. She finally told her sister the reason her job was to keep Elena safe. She told her about the originals and about the moon and the sun curse. More importantly she told her sister that she was only alive to keep Elena safe.

"What do you mean you're only alive to keep me safe?! That's insane!" Elena yelled at her.

"It means that mother wasn't capable to have children so our parents went to see a witch."

"And?" Elena asked.

"And the witch made it possible to her have a child but the witch also warned her."

"About what?"

"That she would have two beautiful daughters but... she had to make sure that the older daughter would do everything she could to keep the younger one, the doppelgänger safe."

"Why?"

"So you wouldn't die when Klaus found you. So he couldn't complete the sacrifice. So he couldn't become the hybrid."

"But we can't run away, Caroline," Elena told her, confirming her fear that they weren't going anywhere. She thought about kidnapping her twin but she knew that she wouldn't get far before the Salvatore brothers found them, or even worse, the Mikaelsons.

"So you're the other Gilbert," she heard a voice saying.

"Who the hell are you?"

"You don't recognize me in this body?" The English guy asked her as he looked at his own body and she realized that the guy in front of her was the famous Klaus Mikaelson. I mean how many people you know that can jump from a body to body? It wasn't hard to guess.

"Klaus stay away from my sister, " she hissed and he smirked at her.

"What do you want?" she hissed at him and crossed her hands.

"I just wanted to make sure that neither you nor your gang was going to do anything stupid."

"And hypothetically if one of us had?" she asked him before smiling sweetly at him.

"You better not. You haven't, have you?" he asked her before coming closer to her angrily.

"Of course not! " If you don't count Damon feeding her, his blood.

"Good," he said before taking a hold of her neck, "I wouldn't want to break your beautiful neck, Caroline."

"How do you now my name?" she wondered aloud before she left, smiling at her without answering her question.

That was the first time I really met Klaus Mikaelson if you didn't count those time he was in Alaric's body and I didn't. But she really didn't have time to worry about him. She really had to get home and try to keep him from sacrificing her sister.

She should've known better than think that she could keep her sister safe. What could one human, one witch and two vampires do against an original? Besides she should have known that in the end Elijah Mikaelson couldn't kill his brother. No matter how many promises he made, they were still a family.

Everyone knew how much Elena didn't want to be a vampire so Caroline made Bonnie do a spell so she woke up as a vampire, not Elena. So when Elena woke up after the sacrifice she was still human but Caroline was not.

Caroline was actually happier this way because she didn't really feel like she had any other purpose as a human than keep Elena safe and this way Elena would be. Caroline liked the feeling of been strong and ageless.

It was Caroline's turn to get a life without worrying about the originals killing her sister. If only she knew that it wasn't over and it definitely wouldn't be the last time she would be seeing Klaus Mikaelson or his family.

N/A: First I thought about making a drabble about Caroline being the doppelgänger but somehow it turned into this :O
Anyways thoughts about this one? Is it worth of turning into a drabble series?
