Summary: Follows 4x01, and is AU from there on. Once Katherine became a vampire, it was up to Elena to carry on the doppelganger bloodline. Now that she is a vampire without carrying on the bloodline, Klaus is worried about his dwindling supply of doppelganger blood to make his hybrids. He was worried that it would be the end of the line for his hybrids. That is, until he gets wind of a woman who has a blood relation to Isobel, which means that she could possibly be the one to either give birth to the next doppelganger, or to give birth to the child that will carry on the Petrova line. He sets out to keep her under his wing and to keep her away from the Salvatores and Elena, though he didn't expect a friendly relationship with his brother to grow into something more.

Warning: This story will grow to be a little on the dark side, though there will be no rape, but some situations could be almost as dark.

Pairings: Stelena, mentions of Delena, a few other canon characters, and Elijah/OC.

Bloodline

Prologue

Kelsey paced the small room of the home that has recently become her prison. Hand pressed against her mouth, her feet moved slowly across the hardwood floor as she circled the small space in the living room. She knew Klaus had said, over and over again, that she was very important. When she asked why, he would give her some vague answer that brought up more questions than it did answer them.

But, now, it was all laid out on the table and Kelsey knew that she had put herself in a dangerous situation. There was choices to be made, and at the age of twenty-two, she wasn't ready to take on such a task. Knowing that Klaus would be tormenting her family line until he got the next key to carrying on his hybrids.

Kelsey was worried about a number of things, one of them being her sworn oath to never have children. A few others being about what would happen to her if she wasn't able to conceive, and if she even was the one to carry on the doppelganger line.

There was also the Elijah question the forefront of her mind.

She let out a shaky sigh, pressing the heels of her hands against her eyes as she felt her heart beating wildly. She cursed herself about not running when given the chance, to have gotten out of there before things even began to get ugly.

The door to the room was opened, Kelsey removing her hands from her face to see the intruder. Her heart fell when she saw the last person she wanted to see standing there. Klaus walked over to her, taking a seat on one of the lush chairs.

The luxury that, at one point, drew Kelsey into staying under Klaus' eye now felt like a lie. Everything that he had told her and the promises and trips that he allowed her to go on now felt like lies. Elijah's friendship was originally set up by Klaus, and even that felt like a lie now, too.

"So, love," Klaus said, Kelsey not sensing any sort of endearment in the way he said 'love', "I think I have given you plenty of time to think about your situation, so I hope you are ready with an answer for me."

"You can't force me to bare a child just so you can keep on creating your hybrids," Kelsey said, her voice panicked and shaky, "I'm not ready to take care of a child-"

"You don't need to worry about that," Klaus said, "I have people ready to raise that child for you. All you have to do is give me a child. Then, you can just live the rest of your life the way you wish to."

"This is sick," Kelsey said, "my answer is no, I would rather be dead before bring a child into this world with the sole purpose of serving you."

"I hope you realize the danger you are putting upon all the people you love," Klaus stated, his friendly tone completely gone, "I get what I want, sweetheart. I kill every person you care about, your parents, siblings, friends. I'll even start with my dear brother."

Kelsey stopped short, swallowing thickly. She exhaled, wanting to completely shout no in his face, but she knew that once he even got close to the people she cared about, she would cave and say yes.

"So, have you changed your mind?" Klaus asked, "this is fair warning, if you deny my request again I will start on my promise."

"I have a few questions..." Kelsey said, "I am supposed to just get pregnant and carry around this child of a complete stanger's? I-I don't do that, I can't just have sex or become impregnated with a child that has no father."

Klaus seemed to think about this, then a small smile cross his face, "what if it wasn't a stranger?"

"What do you mean?" Kelsey asked, "you're not suggesting that...you would-"

"Don't be ridiculous," Klaus said, "I'm not that out of options. What I am saying is that I have witches, and they can do some pretty amazing things."

Things started to kick in her mind, Kelsey shaking her head, "that's impossible."

"I can pull strings," Klaus said, "I can make it happen. So, what will it be?"

Kelsey looked down, not wanting to even look at him again. There was so much at stake if she refused, and yet so much more if she agreed. With a small sigh, she looked up at Klaus.

"Yes," she said, "yes, fine, I will."

Klaus smirked, patting her shoulder, "everything will be fine, all you have to do is carry this child to term and give birth. Nothing will happen to your loved ones."

"I understand," Kelsey stated sharply, moving away from his touch. Klaus only nodded, turning and walking out of the room. Kelsey walked into the small dining room, sitting down in a chair and folded her arms against the table top, resting her head on them.

She realized then, that her choices were not really her own. In the end, she bended to Klaus' will.

Her free will, then too, became a lie.
