Kol made sure that he stayed fully alert and aware as the three of them continued to drink from the doppelganger, paying full attention to the slowing of her heartbeat before pulling himself away from Elena and pulled Rebekah off her and easing Bonnie off her neck.

"That's enough, love," he whispered to her as he held her slightly struggling form. She wanted more blood; the thought alone caused Kol to smile lovingly at the former witch. She'd make a wonderful vampire, he thought to himself.

"What are you doing, Kol?" Rebekah asked him, a little pissed from being interrupted. She was so looking forward to finally killing the doppelganger.

Kol turned to his sister, sending her his most lethal smirk. "Oh dear sister, it is not ending here. Not even close," he replied before tearing into his own wrist, bringing it to the unconscious girl's mouth.

It took a few moments for Bonnie to regain her focus and to realise what she had done and when she did, she let out a strangled cry when she saw Elena lying there. Bonnie started to cry hysterically and repeating over and over again that she just killed her best friend all the while using the sleeve of her shirt she roughly whipped all the blood from around her mouth.

"Why did you do this to me?" Bonnie demanded of Kol. "How could you do this to me?"

Kol had tried to calm her down and she responded by pushing him away from her with such force that he fell of the bed, something she'd never been able to do before without the aid of magic.

Rebekah probably would have laughed at that if not for the seriousness of the situation. Figuring that Kol would rather be alone with Bonnie right now, the female Original picked up the unconscious doppelganger and made to leave the room and nearly being stopped by Bonnie but Kol had grabbed the young Bennett around the waist before she could make a move.

"What are you doing with her?" Bonnie yelled after Rebekah, trying to free herself from Kol's grasp to try and help her friend. "Bring her back!"

Kol had a tight grip around Bonnie's waist as she continued to struggle and scream after Rebekah and Elena.

"Calm down, calm down," he kept repeating to her in a soothing voice. "Everything is okay. Elena is okay. She'll be fine."

After his words, Bonnie's struggling calmed down and she was still in the Original's arms. The only sound was her heavy breathing and occasional sniffle from the tears she been crying.

"She's okay?" Bonnie asked him in a small voice and she turned around to face him.

"Of course."

Elena would be okay eventually but she would never be fine. Elena Gilbert was the price that the Salvatore's had to pay for doing this to Bonnie.

For doing this to him.

You never messed with an Original and got away with it.

Bonnie Bennett had this never ending feeling that something was going to go wrong. Hell, who was she kidding, something was going to go wrong. Something always goes wrong when the plan was concocted by the Salvatore's brothers. The only reason the young witch had agreed to go along with them on their suicide mission was to make sure that they didn't end up dead…permanently, for the sake of her best friend, Elena.

Since leaving Mystic Falls six months ago, Elena had very much so become Katherine.2.0. She had both Salvatore's on either arm, claiming the only reason she hadn't chosen one was because she didn't want to ruin the relationship between the brothers but Bonnie knew better. Elena knew that is she chose one brother, she would lose the other and she didn't want that. She wanted both of them. She wanted to be with one while the other pined after her.

The only difference between Katherine and Elena was that Katherine owned up to what she was doing, she didn't try to act like a saint about it. She knew it; she owned it and she loved it. Obviously none of that made Bonnie like or even respect Katherine, but at least the doppelganger vampire never tried to act all 'holier than thou' about her choices.

Back to the issues at hand, the original plan that she herself came up with was blown to pieces when Elena tried to interfere and ended up blowing the whole thing out of the water and naturally, Bonnie, Stefan and Damon had to run to her aid and straight into the hunters den.

What in the world was Elena thinking when she did this?

It would be a miracle if all four of them made it out alive.

Maybe she should have told Kol what she was doing. But if she had he'd never let her out of his sight ever again. Kol was over-protective of her and he didn't always agree with her choices and decisions but he went along with them to please her, to respect her and that was all she wanted. To be respected.

And not that she wants to brag, but most of the time her plans worked and succeeded.

But this? This was something else entirely. This was something that Kol would not have allowed her to go through with. He would have somehow managed to restrain her with magical-resistant restraints or something and gone on his own. Hell, who was she kidding? He wouldn't have gone at all. He hates the Salvatore's with a burning passion. He would have only gone along to make sure they suffered immense pain and death.

So far, their newest, more dangerous plan had been running somewhat smoothly. They had broken into the hunter's lair and managed to stay out of sight from any possible threats (with thanks to a little spell that she had performed earlier).

"What the hell was Elena thinking coming here?" Bonnie whispered to her two companions. How could Elena even think that coming here was help anything? Hasn't she learnt from past mistakes yet?

"You know, Elena. Thinking she can save everyone by sacrificing herself…ends up making things worse," Damon mumbled in response.

"Her heart was in the right place," Stefan replied, defending his girlfriend.

"Well unfortunately for us that won't help keep us alive," Damon responded with sarcasm.

That was when everything went to hell. They were ambushed, but strangely enough not attacked. The vampires that worked for the hunter had grabbed Damon and Stefan but left her.

She had no idea why. Maybe they didn't think of her as a threat? Did they not know she was a witch? Surely the hunter would want her dead just as much as the Salvatore's.

The feeling of dread intensified as she continued to think up reasons to why they didn't grab her.

Should she go after them? Or should she stay where she was? Leave? Try and find Elena? The young witch had no idea what to do.

She cautiously wondered around the dank caves for what seemed like hours before both Salvatore's finally reappeared in front of her, both seemingly unharmed and fully intact.

"What the hell happened to you two?"

"He wanted to talk to us – about Elena," Stefan spoke. His tone made Bonnie's stomach tighten. She knew that tone. It was the same one he used when they turned Abby.

"What about?" she asked, trying to keep her voice calm and strong.

"He'll let her go under one condition," Damon said, his voice matching his brother's.

Bonnie's heart began to pound and she started to take small steps backwards. "What condition?" she asked but already knowing the answer.

Her ears pricked up when she could hear someone calling out her name, Damon and Stefan -obviously hearing it too- tensed up. It was Kol.

Kol's voice was the last thing she heard before Stefan sped forward and snapped her neck.

"What are you doing?" Kol asked her in a gentle tone, breaking her out of her memories.

Bonnie opened her eyes and looked at him, a tiny smile appearing on her face when she saw all the concern on his face. "I'm trying to remember what happened," she answered.

"You shouldn't torture yourself by doing that," he replied and lied down beside her on her freshly clean bed.

"I know that I really shouldn't be surprised by what happened, but I can't help but feel betrayed by what they did," Bonnie revealed as she curled into Kol's side. "They didn't even try to find another solution. They just went straight in for the kill. I guess I thought I meant more to them than I actually did," she mumbled into his chest, refusing to let tears fall.

Bonnie refused to cry because of them. She'd done too much of that in the past.

"They will pay for what they did. That I assure you of," Kol said to her. He'd make sure that the Salvatore's endured the same suffering that he had. The pain of losing the one you hold dear to you.

At first Kol thought he had lost Bonnie for good at that moment, it wasn't until he composed himself that he remembered that he and Bonnie had exchanged blood the previous night. Not all was lost but he was going to make the Salvatore's experience just that.

Kol's brother, Klaus would certainly be furious with his actions tonight but he will get over it. During the course of Kol's and Bonnie's relationship Klaus had visited them a few time while they were in Paris and although he wouldn't admit it, he became fond of the young girl. Klaus was probably just grateful that Kol had someone to keep him out of the hybrids hair with his antics.

"How did you know where I was? I remember you calling for me before I died."

"Matt came to tell me. He told me everything." Kol had a newfound respect for Matt after that.

"I'm sorry for freaking out on you earlier," she said softly.

Kol shook his head. "Don't apologise, I deserved it. I deserved a lot worse. I completely disregarded your decision and took it upon myself to tell you what you wanted," he responded. "I just didn't want to lose you. I couldn't."

"Why Elena? Why would you make me feed from my best friend and nearly kill her?" Bonnie questioned him.

"When I left, it was because I didn't want to watch you die. I initially had no intention of forcing you to become a vampire but I ran into Elena and she had the nerve to speak of you after what had happened. If she were your best friend like you claim to be then why was she not crying about your death? Why did she not mourn you? It infuriated me that she was still alive while you were about to wither away to nothing. I snapped. She was the reason you were put in this situation in the first place and it only seemed fair that she be the fix."

It was rather easy to get a hold of Elena. She hadn't been ingesting vervain so all he had to do was tear her necklace from her.

"No one here will know that you are a vampire. Once you're ready we'll leave back to Paris or wherever you want."

"What about a day walking ring? It's not like I can make myself one anymore," she said the last bit with a bitter undertone.

"You needn't worry about that. Rebekah is taking care of it as we speak. There is a witch that owes her a favour. You should have one by tomorrow evening," he told her.

"How are you feeling?" Kol asked her after a few moments of silence. "Not being a witch?"

"I know this is going to sound weird, but it feels like I'm still a witch. I still feel it all inside me. I thought that after turning I wouldn't feel it, that it would just disappear or something." Bonnie revealed and sat up on her bed, Kol soon following with a confused expression.

He had met a few witches turned vampires and none of them had their powers. But maybe it was different within the first few hours. Maybe the power leaving her body would be a gradual thing rather than instant.

"Try using your powers. Just throw something across the room."

Bonnie concentrated on a book that was on the dresser and with a quick hand movement the book fell off the dresser and crashed to the floor sending expressions of shock over both their faces.

"I still have my powers," Bonnie whispered with surprise, hand still in the air. Her powers were not as strong as they used to be but they were still there. "How is that even possible? Rebekah said that you could either be one or the other, not both."

Kol, still in shock didn't answer. He couldn't answer. What was he going to say? He had no damn idea how she still had her powers. That was why his mother did not turn in the first place; she didn't want to lose her powers.

"Did you mother still have her powers for a short while after she was turned?" he asked her.

"No, they were gone instantly. She said as soon as she woke she knew she was no longer a witch, said she could feel it."

"What did your mother feed on to complete the transformation?" Kol questioned. He may just have a theory.

"Just a blood bag. Why?" Bonnie answered.

Kol remained silent as he quickly thought over the situation at hand. Could it have something to do with Elena's blood?

"I'll be back in a minute, just need to make a call," Kol told Bonnie before kissing her on the forehead and leaving the bedroom.

The Original pulled out his cell phone and dialled Klaus' number. Maybe he would know something.

"Kol," Klaus greeted. "How is Paris with Bonnie and dear sister?"

"We're in Mystic Falls right now and we have a massive problem. Either you come here or we'll come to you."

Around a month ago Klaus decided to leave Mystic Falls for a while with his favourite hybrid Tyler, who was one of Bonnie's childhood friends.

"What is going on, Kol?" Klaus asked.

"The Salvatore's killed Bonnie but she had my blood in her system. She has completed the transition but she still has her powers," he answered with vague details.

"How is that even possible?" Klaus questioned, a little taken back. A witch retaining her powers after turning into a vampire was unheard of.

"I have a theory…I fed her the blood of the Doppelganger, Elena." Kol revealed and braced himself for the verbal beat down that he was about to receive from his brother and was surprised when that never came.

"How cold of you, Kol," Klaus answered and by the tone of his voice Kol could tell he was smiling.

"You're not pissed?"

"I've got plenty of hybrids as well as Tyler. I've no use for the doppelganger anymore." Klaus confessed.

After Klaus left, he found that he had no need for Elena's blood. He had all the hybrids he needed and he had found the companionship with Tyler that he once had with Stefan Salvatore. Only more improved.

"Well go on, what's your theory?" Klaus pushed, curious of what his brother had come up with.

"You needed the blood of the doppelganger to create your hybrids, so maybe her blood has some kind of mystical quality that allows two supernatural sides to coincide in one body. Not just for werewolves and vampires but for all kinds."

"That is a possibility," Klaus answered after thinking Kol's theory over for a moment. "I'd have to ask around with some people I know to see for sure then I'll get back to you on it."

"Next thing I want to talk to you about is in fact Elena. I'm turning her. I'm draining her of her blood to give to you in case you want more hybrids but after that I'm turning her then dumping her on the Salvatore's doorstep," he told his plan to Klaus as he walked down to the basement of the mansion where a very weak Elena was currently tied to a chair with needles sticking out her, sucking up all her blood into the bags attached.

Her head weakly lolled to look at him when he walked in the room.

It wouldn't be long now, Salvatore's. Kol thought to himself as the compelled nurse continued to work on the girl.

I have decided to continue this thanks to all your lovely feedback.

There will be quite a few flashbacks, including how Bonnie and Kol met and how they fell in love along with why the hunter wanted Bonnie dead and who and what he is.

I hope the whole Doppelganger blood explanation wasn't too far-fetched and congrats to Tauvian for guessing that!

I may not like Elena very much but I feel bad for doing this to her lol. But the Salvatore's have to pay for what they did and unfortunately for Elena, she is the way to get to them.

As you know this is an AU story and here are the changes so far:

They have graduated from school. Bonnie is 18 and was a few months off turning 19. The house they are in is the Mikaelson mansion, Bonnie moved out of home once her father moved away.

Tyler did break his sire bond to Klaus but they ended up reconnecting.

Caroline and Matt are together.

You will learn more as the story progresses.

Next chapter will have some Bonnie angst about her being a vampire.

Please review!

Sorry for any mistakes…and for the overuse of the word 'doppelganger'. I laughed when I read through it and noticed how many times I used it…Believe it or not but I deleted a few of them lol =D
