AN; Hi,
This is my first Vampire Diaries/Originals fanfic, so bare with me here.
I am sorry if things don't really go along with the timeline of the series but it's been a while since I've seen this particular season. It should be right, though.
For the readers of my FSOG fanfic, yes I did upload this... No, doesn't mean that I will update regularly. I still am being 'punished' by my parents. For those who don't get it, read the author's note on the bottom.
English isn' my first language, so there will be typos and mistakes in this fic.

Let's start. Enjoy the first chapter.

Chapter ONE

Adelaide walked in the Mystic Falls Grill after being away to 'study'.

She had not really gone to study, but she did study. She took care of an older woman called Adeline who meant a great deal to her. Adeline was also the woman that 'forced' her to study, so she took advantage of the Internet and took online courses.

Now, after almost three months, she came back.

The first people to catch her eye, in the Grill, were the Salvatore brothers. She had often helped them with her witch powers.

Of course they didn't know she was a Vampire as well as a Witch. If they did, her secret wouldn't be a secret anymore. And it needs to stay a secret at all costs.

There are tales of her, or really the creature she was, hybrid; half Vampire, half Witch. How she was the most powerful and dangerous creature in this world. She would mean the end of every Supernatural being existing. She would mean the end of the world as we know it... Yada, yada, yada.

Because of all those tales, she was in danger. She couldn't trust any vampire or witch, because they would kill her.

She had never had such a thought in her mind. She would never want death upon any human or creature. She has never killed anyone, which is quite impressive for a 1000 year old vampire.

After the brothers, it was Elena along with Caroline and Bonnie that caught her eye. They looked good, including Bonnie. Bonnie was a Witch whom she helped with her power after her grams died. She needed it, the distraction and the need to control her power. If it wasn't for Adelaide, it wouldn't be Bonnie controlling her powers but the other way around. Adelaide can still remember the Emily-incident.

But what caught Adelaide of guard was the person they were conversing with. A person she hadn't seen in almost a hundred years. She had always been two steps ahead of him and his family. They couldn't know that she was alive.

All those years ago, Adelaide had compelled them to forget about her, she had lived in their village when she turned and she had helped their mother and father when they turned themselves. After they had turned, she had compelled to forget her and live on. She had given them instructions for the life ahead of them and left.

She would never forget them. They had always played together and messed around.

Of course he would be here now, the Original Hybrid. Little do they know they are not actually the oldest Vampires alive, but she let them think that.

She took a deep breath, hoping that her compulsion held stance and went over to the group.

It was Bonnie who first saw her and greeted her with a warm smile. "Adelaide." She exclaimed before getting up and running towards the young woman.

Adelaide caught her in her arms and breathed in her scent. She had always smelled good to her, always. She had never felt the urge to kill her, though. No, it was just that Bonnie's scent reminded Adelaide of her childhood.

Elena and Caroline got up after that and greeted her. Damon after that but Stefan didn't come. She could see Matt working and when she waved at him, he came over and gave her a hug, lifting her off the ground before he returned to his work.

She looked at Stefan and saw that his humanity switch was off. She decided to ask later and just go for the easy thing.

"What were you talking about?" Adelaide asked.

They wanted to answer but the Originals looked at her, not knowing if they could answer her as they didn't know if she was Supernatural or not.

It was only Niklaus, though. She wondered where the others were. Did he dagger them again?

"We were talking about ways for me to kill them." He said, gesturing at the Original with a nod of his head. He was probably refering to his family.

Adelaide shrugged. "Well, that's easy. The white oak stake."

Niklaus turned at her and cocked eyebrow. "And exactly how do you know that, love?"

"I'm a witch, how could I not?" She asked him.

"I didn't know, neither did they." Damon said, gesturing to Bonnie, Caroline and Stefan.

She rolled my eyes. "You two just don't care enough about it, Bonnie and Caroline are new to Supernatural stuff, so there's your answer. I actually take my time to study stuff. Plus, Adeline made me study it in case."

Caroline's expression grew soft at the mention of Adeline. "Adeline. How is she?"

Adelaide knew for a fact that Caroline had stopped by a few times during the summer to check up on Adeline. Caroline had always loved the old woman, there just was something about her that made you want to like her.

Adelaide smiled reassuringly at Caroline. "She's doing better. She has told me you came by a few times, I want to thank you for that. You know how much she means to me."

Caroline just smiled at Adelaide and shrugged. Elena was the one that spoke up. "Why? What was going on with Adeline?"

It was not only Caroline's heart that Adeline had captured but also Elena's, Bonnie's and even Damon's.

"She had a stroke." Caroline answered. "She was in the hospital for a little while before she returned home. That was almost two weeks ago now. Have you been back that long?"

Adelaide nodded. "Yes, I was too afraid to leave her side, scared something might happen to her if I did, I didn't think to call anyone, I'm sorry if you are upset with me."

Bonnie smiled and shook her head, but yet again someone else spoke. It was Niklaus. "Look, I hope your grandmother is better as well, but I want to know if we have a deal?"

From what Adelaide could remember, Elijah had always been the sensible and honorable of them. It was Niklaus who was more forward and Rebekah that had an attitude. Finn had always been a bit closed, Adelaide guessed it was because he lost his sister, and Kol had always been outgoing and following Niklaus from time to time. It were the three siblings in front of Adelaide that had sticked together even back in the day when they were all human.

"A deal about what?" Adelaide asked.

"Stefan there," Niklaus said, nodding his head to Stefan. "took something that is mine. I want it back."

"What did he take?" She inquired.

"Coffins. Give them back, or someone here will be the one to pay, got me?"

Stefan grinned darkly. He really wasn't what Adelaide remembered anymore. "Of course." Stefan said. "But you're not getting your family back."

"You daggered your whole family?" Adelaide asked. She was inwardly groaning.

"Well, it was not me who daggered Rebekah in the first place, so no. Not my whole family."

Adelaide rolled her eyes. "Of course not. Okay guys, I'll leave you to it, I have to get going."

Everyone nodded and Adelaide left.

It was days after her encounter when Adelaide was walking out of the Hospital after Adeline ended up in the hospital again. Walking outside of the hospital, she saw Elena getting pushed against the car by Rebekah.

"Hey!" Adelaide yelled, rushing to Elena.

"I suggest you get away, love." Rebekah said, looking at her but not letting Elena go.

"Yeah, and I suggest you let her go."

Rebekah let Elena go and looked at her. "You have no idea who I am, do you?"

"Rebekah Mikealson, Original Vampire and by the looks of it, bully and bitch. Did I get it correct?" Adelaide asked.

"You foolish little girl!" Rebekah spat, before pushing her against the car.

Adelaide didn't really feel anything, but she did act to keep up pretences in front of them.

Before she could cast a spell, Elijah had already knocked her off of Adelaide.

"Leave." Elijah ordered, letting go off her. She stood straight and gave him a daring look. "Are you challenging me?"

"You're pathetic." She turns to Elena and Adelaide and glares at them. "All of you." And she left.

Elijah turned and looked at us. His gaze lingered on Adelaide, and she caught it, but she didn't look away. She wasn't afraid of him, only of him remembering her.

"Well, I believe we have some catching up to do." He said, directed at Elena.

Adelaide entered the grill and saw two familiar faces at a table. She walked closer to Caroline and Elena and was listening in on their conversation.

"Why? Because you and Damon made out?" Elena looked at Caroline, wondering how she knew. "Bonnie spilled the beans."

Adelaide walked closer. "You and Damon Salvatore kissed?"

Elena looked up at the woman in front of the two.

"Yes, she did!" Caroline said, before turning to her friend. "Look, Elena, I'm just saying that when Matt kissed you freshman year, you called me the second it happened and now, I have to find out later, from somebody else?"

Adelaide listened to Elena when she told Caroline that she didn't know how she felt about it herself, when Rebekah came.

"Carefull Caroline, it's all good until she stabs you in the back." Rebekah said.

Adelaide groaned internally, before speaking up. "Hey, guys. I'd love to chat more but I have to go."

She went to the bar to pick up her order and went back out the grill. She moved to her car with the blonde original's brother on her mind. Seeing Rebekah again brought back memories of the male original of the night before. How gentil he had been, and concerned. He had felt the pull she felt as well. It had to be.

Elijah Mikealson had just told Elena Gilbert to leave, but not Adelaide. No, Adelaide still stood there. She was looking at the Original vampire in front of her. If she wasn't wrong, and they Vampires hadn't changed too much, Elena was lucky it was Elijah and not Kol or Klaus, though Adelaide was sure that Elena was aware of the horror that was Klaus.

"Are you okay, miss?" Elijah asked, worry was in his voice.

Adelaide nodded, thankful for his question. "Yes, I am quite alright."

"Are you sure?" Elijah asked. "You seem quite shaken up."

Adelaide laughed humorlessly. "That has nothing to do with your sister, trust me."

"If I may, what does is it have to do with?" Elijah inquired, being worried about the beautiful young lady in front of him.

She wasn't sure why, but she answered him... truthfully. "I... uhm... Adeline, she is in the hospital. She had another stroke, it is her second and I am worried it won't be her last."

"You're worrying you're going to lose her, aren't you?" Elijah asked the troubled woman in front of him.

She nodded. "I have had her around me for so long. She is like me own grandmother."

"Like your own, but not really? ... I am sorry, it was none of my bussines." Elijah apologized.

Always the gentleman, Adelaide thought.

She smiled reassuringely at him. "No worries, it's okay. I have no family, Adeline took me under her wing as if I was the granddaughter she never had. I'll always be grateful to her."

Elijah smiled at her before frowning. "Not to intrude or anything but, were you going home? Alone?" When Adelaide nodded, Elijah's frown deepend. "You couldn't possibly, it is dangerous out there at this time. Definitely for a beautiful young woman as yourself."

Adelaide smiled slightly at the hidden compliment. "Thank you, but I'll be fine. I don't live so far from here, so I'll be fine walking there."

"Walking?" Elijah sputtered. "Walking? No, miss, I couldn't possibly let you! I'll give you a lift."

"Adeline told me not to go anywhere with strangers." Adelaide teased.

Elijah held out his hand. "Elijah, Elijah Mikealson. Pleasure."

Adelaide took his hand, and he brought hers to his lips. "Adelaide," she answered, "Adelaide Ackleson. Pleasure is all mine."

Elijah chuckled slightly. "I'd disagree. Milady?" He aksed, offering his arm.

And that was how the two actually met.

Ever since the night before, she couldn't get him off her mind. The invitation the his ball with the personal note on the back, didn't help at all.

Dance with me tonight?
