Klaus's Pov

Elena returned Rebekah back to him as a part of the deal, where he won't harm anyone she loved. He wanted his sister back, so he agreed. But the doppelgänger told him, that she was the one who stabbed Rebekah and as far as he knew his sister, the first thing she would do after waking up, would be ripping her throat out. He needed the blood-bag alive for his hybrids after all and daggered Rebekah again.

Later, when he called Stefan after finding the coffins missing, Stefan told him that now that he was free, he would take his revenge and he would never see his siblings again.

He got the location where Stefan had hidden the coffins with the help of the witches and got them back, after he threatened the elder Salvatore and the witches as well.

Now, he just had to wait. Once he was done building their house, it would finally be the time to bring his family together.

Stefan's Pov

He didn't sleep the whole night he was at Athena's house. The only thing in his mind was revenge. Now that he was 'free' he wanted nothing more than to hurt Klaus and the only way to do that was to take his family away from him. So, he stole the coffins that contained Klaus' siblings and called Bonnie to hide them in the abandoned house. Klaus called him later to threaten him, but he knew that Klaus's family was his only weakness. So, he told Klaus that if he kills everyone he loves, he will never see his siblings again.

.

When he reached the abandoned house the next day, Bonnie was already talking to Elena about the coffins. He didn't want her involved, things would become even more complicated with her here and he was not was not in his right frame of mind right now. Bonnie told them, that she needed to find her mom to open the fourth coffin. He was at Elena's house, when he called to ask her if they found Abby, but she lied to him. The information about the witch was lying on the table, so he decided to go there himself.

Elena was already outside when he reached Abby's house. They had a fight, which resulted in Jamie shooting him with the wooden bullets and tying up Elena. Meanwhile, Abby drugged Bonnie and took her somewhere. Later that night, Jamie told them that he was compelled. Elena managed to untie herself, knocked Jamie down and helped him in removing the wooden pieces from his chest.

She had just removed the last bullet, when he looked at her properly after a long time and noticed, that there was something different about her which he hadn't seen before.

He was still lying on the ground, but couldn't stop himself from saying it out-loud, "You've changed."

"I kissed Damon." She whispered while looking down.

His brows furrowed in confusion. "I know. I was there when you kissed him, Elena." He said. What had he missed?

She was still looking down when she said, "No. I…" she took a deep breath and looked him in the eyes. "We made-out after Mikael was killed."

He didn't say anything. What could he say? He didn't tell her in that moment, that he loved her. For him, it had never been Katherine, she was the first and only person he fell in love with, unlike Damon. He wasn't sure if his brother really was in love with her or it was because Damon had wanted revenge from him or was the love Damon had for her was simply misplaced? Katherine never loved him and Elena was just like her. Was it possible that he was trying to find his lost love in Elena? He knew she loved Damon and he had always been in love with her, but he thought that his brother liked Athena and he had been sure of it. He was certain that Athena liked Damon and he liked her, maybe his brother was already in love with her, but Damon had always been hard-headed. He had been wrong, perhaps. One thing he knew for certain, they were all in this situation because of Katherine and he sighed.

He looked at her when she said, "He's always been there. Every time you broke my heart, he was there to pick-up the pieces and I didn't realize when, but… I love him." she finished with a whisper.

"You are in love with my brother." He said it slowly and the words sounded empty to himself. Out of the corner of his eyes, he saw Elena wince at how he said it. But, that was what it was. She was in love with his brother. He should have known it, in fact he knew it. He was just trying to run from the reality, avoid it as much as he could. He felt a pickling sensation behind his eyes and closed them. He didn't want her to see how much she affected him, that he was in love with her and it had never been anyone else.

"I'm sorry, Stefan. I love you. I will always love with you and I know that you don't love me anymore."

She was gazing at him with those beautiful brown eyes, he loved. He could see that she wanted assurance of any kind, but he wasn't able to give it to her. It was over and they both knew it. It was better this way. Maybe his brother will find the happiness he was searching for. Maybe, this was how Damon felt when Katherine left him.

He looked at her for a long time and said the words which shattered his heart to pieces. "Yeah. I am sorry too."

As he turned around to leave, he felt tears sliding down his cheeks, but he ignored them and left.

.

He took his time before going back to the Boarding house. He didn't want to be here anymore than it was necessary. He needed a few things and he would go back to Athena's place. The first thing he saw when he entered was Damon and his anger flared.

"You let Klaus get the coffins." He stated.

"Don't worry. I was able to get one of them out of there in time. The locked one." Damon replied smugly.

"Probably a good choice. Bonnie's mom doesn't have any power. It turned out to be a waste. I'm leaving. It's been that kind of a night." He said as he turned to leave.

"Is Elena okay?" he stopped and closed his eyes at Damon's question.

He broke one of the chairs and stabbed Damon in the stomach with it. He took satisfaction from the pain Damon was in.

"I take it you two had 'the hard talk'." He shook his head as he turned around, but just then Damon grunted as he pulled the wood out with a pained groan. "It was a mistake, Stefan. I am not in love with Elena."

He sighed as he heard this. He already knew it, this was the confirmation he needed a few days back, but it was too late now.

"You should've thought that before you made-out with my girlfriend. But its alright now. You can do as you wish. We are no longer together." He said hoarsely.

His eyes widened in surprise, but thankfully didn't say anything, else he would have killed Damon. Then, Damon pulled out a dagger that he had seen before.

He looked at it with dumbfound expression and managed to ask, "What did you do?"

General Pov

She apparated outside the Mikaelson Mansion with a loud crack. It was just as big as the Salvatore Boarding House, if not bigger. Before she could move forward, he came out along with many vampires and she tensed. As she looked at them, she saw Tyler standing there.

"Tyler?" She was sure he was not a vampire, the first time she had met him. "You are a vampire?" She asked curiously. What was with this town? It had more supernatural creatures than humans.

Tyler shifted uncomfortably on his feet and looked at her, even though he didn't reply.

"Athena." Klaus whispered.

"I wouldn't have come, if it wasn't important." She said uneasily.

"Would you like to come in?" he asked her hopefully.

She hesitated at first, but then nodded and went inside. The vampires and some workers were renovating the building, as she looked around.

"I'm building this home for my family." He told her with a gentle smile and her eyes tightened at that as she struggled to keep the hurt hidden.

Her fists clenched, as she struggled to keep herself under control, when she noticed vampires crawling in the place. She felt uncomfortable and uncertain. He'd already tried to kill her once, what's to say he won't again and now, he practically had an army to help him.

He noticed her discomfort, when he saw her looking at the door with trepidation.

"Leave. You can come back in an hour." He ordered everyone, still looking at her.

Once they all left, she sighed with relief. She looked at him and saw Tyler still standing there, looking at her curiously.

Klaus looked from her to Tyler and then told him with a smirk, "It would really make me happy, if you won't tell anyone about this little meeting."

Tyler looked at both of them apprehensively, but left with a nod.

"Thanks. You are enough, I don't know how I would've handled a whole army of vampires." She murmured as she sat on the armchair.

He winced at that. Yeah, he had that coming, he thought with a sigh. There were so many questions storming in his mind and he, literally, had to bite his tongue to stop himself from asking them. He took a seat on the sofa, in front of her. He didn't know what to say, but he knew that he needed to apologize before anything else.

"I want to apologize. What you told me was unexpected and you must understand that in my 1000 years on this earth, I haven't heard about a vampire fathering a baby. It wasn't my intention to harm you in any way." He said looking at her, his voice completely serious.

Perplexed, she glanced up at his face and sucked in an astonished breath. He was apologizing to her? Even though she nodded, she wasn't ready to forgive him- because she was angry still, so she looked away.

She was still thinking about how to tell him about Esther and the witches; then there was the fact, that Rebekah had asked her to discuss the matter calmly, as if she was the one with anger issues, she snorted at that. She wanted to hear the truth from him one last time, maybe because she knew she would never get past this until she faced it head on.

As they both sat there, the room fell into tense silence. She wasn't comfortable sitting alone with him and would have felt better if Rebekah was there with them. She seemed nice, much better than Klaus.

"Where's Rebekah?" she asked him.

"She's not here." He replied.

"You didn't kill her, did you?" she tried to joke, but they both knew that she was serious.

"She's alive." He answered in a clipped tone and the silence continued.

It was getting beyond pathetic. She wasn't even able to talk to him. She just needed to tell him about his mother and then leave, once and for all, she thought. But when she opened her mouth to tell him that, entirely something different came out.

"I've read that vampires cannot procreate and if you've been a vampire for 1000 years, then how can you be my father? And I know that James Potter was not my biological father." She took a deep breath and continued, "There was this picture, mum left in her diary. I have blonde hair in it and I am sure the color changed after the blood-adoption. It's fairly common." She ranted without a conscious thought.

"Can I take a look at it?"

"What?"

"The picture you mentioned, before you were adopted. Where is it?" he asked expectantly.

"It's in my vault in Gringotts." And he raised an eyebrow at that. "It's the Wizarding Bank in England, where mum and James left money for me. I was angry, so I left it there."

They both went quiet for some time after that.

She whispered to herself, "Is it possible that someone else could be my father?"

"No. James was the only man your mother loved. I was a mistake." He told her.

"How would you know? You and my mum just had a one-night stand. It is entirely possible that she slept with someone else as well. You are not my father. You said it yourself that it's not possible. James wasn't as well." She shouted at him with fury on her face and his eyes widened at that.

"Lily wasn't just a one-night stand. She was the only friend I've had in a long time." He told her.

"What? But you said…"

He wanted her to know, that her mother loved James and her sleeping with him was because of a moment of vulnerability and a spontaneous act on both their parts. So, he told her. How he met Lily, about their friendship, about the man that attacked her and that she accepted him even after he killed that man in front of her, how sleeping together was an impulsive decision in a moment of weakness. After which he compelled her to forget him and how he locked his memories of her.

"That still doesn't explain how you can be my father. You are a vampire." She snapped at him.

"No. I am a hybrid."

"What?" she looked at him sharply.

"My father was a wolf and I got the werewolf genes from him. I am a werewolf turned into a vampire. A hybrid." He informed her calmly.

That alarmed her and she asked, "How? I haven't heard anything about your species before."

"That's because I am the original hybrid, sweetheart. I created others."

"Tyler…?" She asked and he nodded.

"You said you got the werewolf gene from your father." She looked at him for confirmation and he nodded again.

"H…How is the gene activated?" she was sure she knew, but it couldn't be. She just had to ask him.

"The werewolf gene is triggered by taking the life of a human." He tried to appease her, but he didn't know that it would do anything but that.

"Then you cannot be my father or I would have triggered it years ago." She told him without thinking.

"What do you mean 'you would have triggered it years ago'? You are just a child." he asked angrily through clenched teeth.

"I am 17." She muttered petulantly as her gaze snapped up to meet his.

"That's what I want to know, darling. What do you mean by years ago?" he hadn't noticed, that they were standing close and shouting at each other.

Rage consumed her. "You have no right to demand anything from me. I've been taking care of myself since I was a kid and I don't need you to act all mighty. Especially not after you tried to kill me." She growled at him and he flinched like she'd just punched him.

He closed his eyes and took a deep breath. It won't do good if both of them would be angry. It won't answer anything. How exactly do you deal with a teenager? And specially if the said teenager is your daughter?

"I'm sorry for yelling at you and for trying to kill you. My intention was never to harm you or do what I did. I was pissed, because you reminded me of Lily. All the memories came barreling down and it scared me. It was too much… I couldn't process it all. It was my fault and I took out my anger on you for which I'll never forgive myself." He whispered sincerely.

She swallowed. She didn't know what to think about his confession. She was confused, scared and overwhelmed. On the other hand, he might have been as well. She was trying to process it all. But this whole situation she had found herself into was because of the fact, that he refused to deal with the aftermath of what happened between him and her mum. Instead of dealing with it, he had compelled her mum to forget him and erased her memories from his mind. It was the main reason she was in this predicament. She didn't know what it was like for him, so even though she couldn't respond, but nodded at him.

She couldn't forgive him. Not yet. Maybe in the future.

"Would you tell me how you could have triggered the gene years ago? You don't have to tell me right now, if you don't want to. I can wait." He finished lamely and then closed his eyes. He wanted to hit himself. Where exactly did his confidence go?

She bit her lower lip and looked at him with a thoughtful expression on her face. Then she nodded and said, "One of the teachers in my school tried to kill me when I was 11, but he was burnt when he touched me and died. Later, Professor Dumbledore told me that because my mum died to save me, her sacrifice and love left a powerful and protective charm in my blood. And because of that, Quirrell wasn't able to touch me."

Everything related to witches was tricky, but he thought about it for a moment and told her, "It maybe because you didn't actually kill him. You had Lily's protective charm inside your blood and he touched you, so he died."

"That still doesn't explain it. If I really do have your gene, then I should have triggered the curse. I killed Voldemort and it's been months."

Shocked, he stared at her for a long time but then gritted out, "Why would a young girl need to kill someone?"

Athena looked away, her hands trembling. She didn't trust him and didn't wanted to tell him anything. So, she turned towards him to tell him that, but stopped when she saw the look in his eyes. He was staring at her with an unfathomable expression in his eyes.

"Please tell me." He almost pleaded.

She was uncertain about telling him anything, but decided to tell him the basic without giving-away anything else.

She started, "Before my birth, a prophecy was made which stated that, a child would be born as the seventh month dies and will have the power to defeat the Dark Lord. I was born on July 31st. My parents went into hiding when I was born, but one of their friends betrayed them. He killed them, but when he fired the curse at me, it rebounded on him and he vanished. Everyone thought that he had died and I was sent to live with the Dursley's."

"What? You were sent to live with Lily's sister?" He asked through gritted teeth.

"Yeah. The charm mum placed on me when she died was in my blood, which was tied to aunt Petunia. I needed to stay with her until I reached the age of majority." She said bitterly, but continued, "Voldemort was alive and came back when I was 14. He killed everyone I've ever loved and I lost everyone because of him."

"Lily trusted James's friends. Wouldn't they have protected you better?" Now he was sure that everything she told him about James and his friends was connected to magic.

"People in my world are prejudiced. Remus was a werewolf, so he wasn't able to get my custody, after Sirius was falsely accused of killing my parents. He was my Godfather and I should've stayed with him." She smiled sadly with a faraway look in her eyes.

He didn't ask anything after that. He couldn't. He could see by the way, her eyes filled with tears as she mentioned her Godfather, that she had lost him as well. So, he stayed quiet, but his mind was racing rapidly. Lily and James died to save their daughter. His daughter, and he suddenly was grateful to the man, who he had detested without even knowing him. he understood what she meant when she told him that, 'James Potter was her father, who died saving her life'. He looked at her and noticed that even though she was looking at him, but her eyes were vacant and hollow. Who was he to her? Nothing. He's never been there for her, she'd never known about him and they wouldn't have even met each other, if Lily hadn't left his picture and the letter for her. And what did he do? He didn't give her a single chance to explain herself and almost murdered his own daughter because he couldn't stand the fact, that she reminded him of Lily. He was telling her the truth when he told her that he won't be able to forgive himself for hurting her. She shouldn't either. He swallowed thickly.

"He took over the ministry, he killed hundreds of muggles. Muggle-borns were killed at sight. There was a war and we fought. We couldn't let him win, he would have killed every muggle if he could have. Someone had to do something." She said quietly at that.

"Muggles?"

"Non-magic folk. People in wizarding world are divided. Purebloods, who are born in a family with magical blood line, which could be traced back to the founders." She said with an eyeroll. "Muggle-borns are those, who born to muggles, non-magical people. And half-bloods are those whose parents are both, a pureblood and a muggleborn."

"Your world is divided on the basis of blood?" he asked bewildered.

"It's not the only thing." She said.

He couldn't process that people and bigotry like this still existed in the world. A world which was hidden from everyone else in the world.

He wanted to know more about it, but then suddenly she exclaimed in a loud voice "Wait! I know how to confirm it. How stupid can I be?" And, he looked at her at that. How could she confirm it? They couldn't exactly get a DNA test, now could they?

"Confirm how?" he asked but she didn't reply.

Athena pulled her wand out and shouted, "Expecto Patronum."

A silvery-white bird appeared, they both gasped in unison and Klaus looked at her in surprise. Why was she shocked?

"What? I don't understand." She mumbled under breath.

"What is it, sweetheart?" he asked.

"My Patronus was a stag. Why has it changed now?" she whispered still in shock and he didn't answer. He knew nothing about any of it.

She came out of her shock, muttered something to 'the bird', which looked more like a crow in his opinion and he saw as it flew out of the house.

He cleared his throat to ask her about it and what she was doing, but she answered before he could ask, "Wizards have a different way to test their inheritance. Its like a DNA test in the muggle world. I don't think you being a vampire should be a problem. Goblins don't care what laws wizards follow. They have their own laws." When she saw his confused expression, she continued, "Oh! We aren't allowed to tell anyone, especially vampires about our existence. It's one of the most absolute law and can land us in prison or we could get our powers stripped."

"What? You have your own laws and your own prison? How many of you are out there?" he asked with equal parts shock and curiosity.

"We have our own world, which is hidden from anyone who doesn't belong there. And I can't tell you any more than that. I'm sorry." She said as she looked at him warily.

He wanted to know more, but he calmed himself. He wouldn't hurt her than he already has and he wanted her to trust him, so he merely nodded at her.

As they waited quietly, it gave him some time to think about everything she told him.

Just then a creature appeared in front of him and his eyes widened in surprise. The 'goblin' as she called him was a small humanoid with huge eyes, had pointed nose and ears along with long fingers and feet.

He was still staring at 'the goblin' when it said in a squeaky but firm and loud voice, "My name is Bogrod and I am here to see Athena Lily Potter."

"Thank you so much for coming within such a notice." Athena said to him. "Oh! Would you like to sit down?" she asked him awkwardly.

Klaus looked with narrowed eyes as Bogrod sat down, snapped his fingers and a jeweled dagger along with a piece of parchment appeared in front of them. He tensed. Why would he need a bloody dagger for a blood test? And why was he using a parchment in the 21st century?

But before he could question him, the goblin squeaked again with his nasally voice, "We will slice your palm with this knife and drop some of your blood on this scroll, then a list will appear which will provide all the information related to your family, blood line and magical inheritances, if you have any." Then he unraveled the scroll and picked up the jeweled dagger.

Athena held her hand out without a thought, but he blurred to her, held her wrist in his hand and snatched it back, before the dagger could touch her palm. She looked at him surprised and the goblin just stared at him, looking bored. He focused on Athena, and asked, "Are you sure it's safe? You don't need to do this. I believe you." Yeah, so he lied at the end, but he couldn't let her get hurt, even if she was not his child.

"There is nothing to be worried about. It's fine." She answered him.

She pulled her hand from his and held it out once again to the goblin, who sliced her hand in one quick moment, letting the blood fall on the scroll, like spilled ink. She didn't wince and all of them focused on the scroll as the blood began to sink in it, before it disappeared. Suddenly, letters started emerging on the scroll, before rearranging themselves into an orderly list.

Inheritance Test

of

Athena Lily Potter

Father: Niklaus Mikaelson.

Father: James Potter by blood-adoption, deceased.

Mother: Lily Evans nee Potter, deceased.

Godfather: Sirius Black, deceased.

Living Relatives:

Finn Mikaelson. (paternal uncle)

Elijah Mikaelson. (paternal uncle)

Rebekah Mikaelson. (paternal aunt)

Kol Mikaelson. (paternal uncle)

Core witch. (From maternal side)

Wiccan witch. (From paternal side)

They both were still staring at it, when Bogrod said, "That would be 20 galleons."

Klaus looked up when Athena muttered, "Yes. Sorry." As she fished out some gold coins from her purse, and gave it to the did the purse come from? He hadn't seen it before. She thanked Bogrod, before 'it' disappeared with a snap of his fingers.

"Someone in your family was a witch?" she asked quietly after a long time.

"Yes." He replied gravelly.

"Well. That explains how I am able to do magic without a wand." She murmured.

He nodded. That certainly made sense, then they both sat there silently deliberating.

Everything she'd told him, weighed heavily on his mind. It couldn't be denied now, even the names of his siblings appeared on 'the scroll'. She was his daughter. What had she been through? If he would've been there, if he hadn't erased both their memories, his daughter wouldn't had to face everything alone. He would have killed anyone, who would have tried to harm her in any way. His jaw clenched as his eyes tightened. He was well aware of his grip tightening on the scroll he was holding, and felt her eyes on him, so he released it. There were so many things in his head right now, but he didn't want to frighten her even more than he already had, so he stayed silent. Every second of silence did nothing, but increased his rage more. Someone had tried to kill her and he wasn't there. She said she had lost everyone she has ever loved, who else has she lost? His family lost all hope when Henrick died, but here she was, trying to find her last living parent in hope of a family and he all but crushed it. Her existence made no sense at all and it was a miracle. She was a miracle. She should have been loved, but instead of living with her own family and with him, she lived with those horrid people all her life.

'He would find them and kill every last one of them.'

He glanced at her, her heart was pounding and she was looking at him with no small amount of trepidation. He closed his eyes briefly to calm himself and felt his anger fade. He could tell that whatever she had told him, wasn't even half of what she had been through and he felt pain at the thought, that she wasn't comfortable enough to tell him. She didn't trust him and he had no one to blame but himself.

In that moment he vowed that - 'he would be the family she deserved, he would be the parent she has never had, he will make her trust him and he will protect his daughter, even with his last breath.'

Meanwhile, Athena wanted to tell him about Esther, but there was only one thing in her mind. His mother was dead. Why would he believe her? He already tried to kill her once, and that was over nothing. She wont even have the chance to think this time, before she'll find herself alongside Esther and those thousand witches. But, he needed to know because, as she thought more about it, she realized that Esther was not only trying to kill him and Rebekah but all of their siblings. She couldn't let that happen. Even if he doesn't like her, she had to tell him. She'll deal with his anger when it comes.

So, she braced herself and said, "There is something else you need to know."

But before Athena could tell him, one of his hybrids came in with a panicked expression on his face. Klaus's brows furrowed, but then the man's mouth opened in a silent scream and then he fell down. They both looked up at the same time to see a man standing there with the heart of the fallen hybrid in his hand. She felt sick. It was a good thing she was in shock or she would have vomited all over 'her father'. To distract herself, she looked at the face of the man standing there.

He was a handsome man as tall as her father, with short brown hair and mesmerizing, hazel brown eyes.

Klaus's eyes widened as he looked at the newcomer.

"Elijah."

EN:Athena would meet all her family in the next chapter. Revelations will be made. Damon and Stefan would find out about Athena's parentage as well.
