Grimmauld Place

Athena sighed tiredly as she entered the kitchen and slumped on the nearest chair. Klaus and Kol followed her at a leisurely pace, while Stefan went out to hunt and to talk to Caroline as none of their phone's never worked inside the house. She closed her eyes and thought back to the discussion they had with the Weasley's. Things could have been a bit better, but at least no one tried to kill each-other and it was a feat in her opinion. Everyone had been shocked when she had told them that her family were the first vampires in history and were created a thousand years ago, known as Originals and her father was a hybrid. Everyone was astonished and unnerved by both the originals present, but thankfully they didn't look at her like she was a freak of nature, which she definitely was. They obviously knew about the existence of vampires, but no one had heard anything about a hybrid before. No one understood how a vampire could impregnate a human, even if the said vampire was a hybrid, but Hermione had offered to search for her and Athena knew there was no use in telling her friend to stop. Hermione was nothing if determined and she would do anything and everything to search for answers.

Klaus and Kol were sitting beside her with a glass of champagne, while she was about to take her leave. She had a tough day and just wanted to retire for the day, when Stefan blurred into the kitchen and she frowned at him. It hadn't been long and it definitely should have taken longer for him to hunt, but one look at his face and she knew that something was terribly wrong. His face was pale and he looked like he would break any second. In an instant, she was out of her seat and in front of him as she asked hurriedly, "Stefan? What is it? What's wrong?"

He blinked as if shrugging something internally and his gaze went to Klaus, who looked back at him curiously.

"It's Damon." There was nothing but panic in his voice as he whispered quietly, but urgently. "He's been bitten." Stefan's eyes flipped from Klaus to Athena, knowing that he won't be getting the cure easily and from what Elena had told him, they didn't have much time.

Athena sucked in a harsh breath. Even though Stefan hadn't said the words, but she heard him loud and clear. Damon was bitten by a werewolf and she knew what it meant. She sucked in a horrified breath as her heart plummeted in her stomach. She felt panic churning inside her which she hadn't felt in a long time. In that moment, she forgot that he was a killer who had killed her friend so ruthlessly in front of her. That he was someone who loved someone else, while he hated her. All she knew was someone she loved was dying and she couldn't bear the thought of that. "What? How did that happen?" she choked out.

Stefan shook his head and murmured, "I don't know. It was Elena. She told me that it all happened in a matter of seconds. Damon, Caroline and Elijah were there when the wolf attacked them…"

They heard the sound of a glass breaking and tuned to see Klaus and Kol standing and looking ready to murder anyone. Klaus was holding the now broken glass of champagne which he had crushed with his grip. His eyes were burning fire as he stared at Stefan and roared, "What were they doing with my brother?"

"Elijah is fine. It's Damon and Caroline." Stefan told him.

"Caroline?!" Athena gasped. How had someone manged to bite two vampires together?

Stefan met her horrified gaze with his panicked one and said, "The wolf didn't bite her, but she got some injuries which aren't healing. The part where the wolf scratched her is infected and inflamed."

Now that he knew that his brother wasn't harmed, Klaus frowned and said thoughtfully, "But that's not possible. I myself have some experience and any scratches should've healed after she took some blood. The only thing that can harm a vampire is a werewolf bite."

Stefan shook his head and muttered urgently, "We don't have time for this right now. Elena said that Caroline's already showing the symptoms and Damon's behaviour isn't exactly… lucid. It's spreading faster than it did before. Bonnie's trying to search something… anything to slow it down, but she hadn't been successful yet."

"What?" Athena asked alarmed as her eyes widened. "He's been bitten before? So, there's a cure? Do you have it?" she fired one after another.

"That's what I'm here for. I need the cure for my brother and Caroline." Stefan finished staring at Klaus, who stared right back at him nonchalantly.

Unknown to the silent conversation going between the two, Athena frowned, confused. She looked at Stefan and told him apologetically as dread filled her, "Stefan, I… we haven't heard about a cure which can cure a vampire from the werewolf bite."

"No. But he does!" Stefan replied as he gestured towards Klaus, his eyes never straying from the hybrid's. He knew that it won't be easy, but he wasn't going to let his brother die or even Caroline for that matter, not if he could do anything about it.

Athena's eyes went to her father frowning even more. No one knew that there was a cure and it could save the vampires from werewolf bites. They would be able to save Damon and Caroline, and she sighed with relief. But her relief was short-lived when she heard the next words.

"Now mate, why would I do that? You killed my brother and you along with your brother tried to kill me again and again." Klaus asked amused, staring right back at the vampire.

Stefan stared at Klaus with his jaw clenched, while Athena gaped at him. She had forgotten about the animosity between her family and the Salvatore's.

"I'll do anything you say! My brother's dying and he doesn't have much time." Stefan begged as he took an unconscious step towards Klaus and Athena could see the desperation clearly in those green eyes. She did not have siblings but seeing Stefan so distraught and begging for his brother's life, even though he had been hurting because of what Damon did, made her heart clench with grief even more. Seeing Stefan like this made her decision for her. She wouldn't let Damon die. Not because she still loved him, but because of Stefan. It was clear for everyone to see that without his brother, Stefan would flounder. No matter how much the brothers fought or hated the other, they loved each-other more.

Klaus took another glass from the cabinet and sat down on the chair beside Kol, who was watching the exchange with interest. He poured champagne in the glass and took a sip. He knew Athena was watching him, he also knew that she was close to both the Salvatore's, but this wasn't about her. This was about him and how the brothers and their merry gang had tried to destroy his life by one thing or the other again and again. Not to mention that they had killed Finn in hope that it would kill them all. They've deceived him again and again. The only reason they weren't six feet under was standing right next to the ripper. He didn't want to lose his daughter now that he knew of her existence and knowing her bleeding heart, she would do something that would make him loose his control and then he would lose her. So, he looked at Stefan and said beguilingly, "We all know what happened last time you said those exact words. Always on and off the wagon! Your humanity if your biggest flaw. You aren't of any use to me. There's nothing I want from you. Especially now, that I've everything I want."

"Please! The wolf that bit Damon wasn't like the one we've encountered before. We don't know how long they have! Elijah killed him, so we don't know anything about it and how it's gonna affect them. From the looks of it, even Caroline doesn't look good."

Klaus shrugged unconcerned, even though his eyes narrowed from the knowledge that there was a different kind which they had no idea about. They could be lethal, especially considering the fact that they were so well hidden that even he had no idea about them. Even Kol had stopped looking amused and was curious.

On the other hand, Athena's eyes widened when Stefan said it wasn't like any wolf they've seen or heard about. The only other werewolf known were wizards and American ministry wasn't as strict when it came to magical creatures. So, it could have been a wizard, but what was a wizard doing in a backward town like Mystic Falls? It wasn't possible, was it? It couldn't be a Death Eater, but with her luck it was possible. And then there was the man who had cursed Lavender. She was almost positive that whoever the wolf was, he in the town for her. She gulped and her eyes went to Stefan as she whispered, "Do they know his name?"

Stefan turned his head towards Athena, brows furrowed at the question. It wasn't important. He needed the cure for Damon now, but when he saw her expressions, he answered anyway, "It was someone named Greyback."

Athena's eyes widened with horror when she heard the name and alarm bells rang in her head. He was there for her, but how did he know where she was? That would mean that the others who had escaped after the war knew as well. Caroline was innocent and even Damon didn't deserve it. She felt bile rising in her stomach when she realized that another two people would die because of her. She made a mad dash over to the sink, hands gripping the counter as she puked.

The vampires watched in alarm as she paled drastically after hearing the name, before turning green and upchucking in the sink. Klaus blurred towards his daughter and starting rubbing soothing circles on her back, while he held her hair away from her face with her another hand. Once he realized that she was dry heaving, he pulled her towards the chair and called Kreacher, ordering him to bring a glass of water.

Kol and Stefan hovered around her, worried and confused, even though it wasn't difficult for the three to register that it had something to do with Greyback. Klaus kneeled in front of her as she drank water and noticed that she still was pale.

"Darling, are you alright?" Kol asked after she kept the glass down and she nodded.

Klaus looked into Athena's eyes and saw the faraway look in them. He knew she had been though a war, but that was about it. He had been patient, but he couldn't anymore now that he knew that something was wrong and it didn't take a genius to realize what it was. He looked into her eyes and said softly, "Do you know him? You can tell me anything, sweetheart. I won't let anyone hurt you."

Athena looked at her father and couldn't help the small smile that graced her lips. Yeah, she had people who cared about her, but apart from Fred no one had ever said something like this to her. Maybe this was why family was important. But she became serious soon as she realized that she had to tell him about her past. Even Kol and Stefan were looking at her with anticipation and she could see hope in Stefan's eyes. Hope that maybe they could save his brother. She took a breath and said quietly, "He was a Death Eater and was after me. I just don't know how he found out where I was?"

Stefan sucked in a breath as realization hit him. She'd told him about Death Eaters and he knew that they were after her, but Klaus and Kol were oblivious.

Kol asked, "Death Eater?" while Klaus asked at the same time, "Why was he after you?"

Athena wanted to tell them everything, but she was more worried about Damon and Caroline. She had no idea what would happen to them and if her father had the cure, they could at least save the two, who shouldn't have been dying because of her. Saving them was paramount, but she wasn't sure if her stubborn father would give the cure to the Salvatore's or not. On one hand, she could understand why he was reluctant to help them. They had killed his brother and had tried to kill the family. But on he other hand, she knew that no matter what, she would do everything to save the vampires, no matter even if they hated her. Once again, it was all because of her. How many people were going to suffer because of her existence?

"I'll tell you everything you want to know, but we have to save Damon and Caroline and you have the cure. We don't have much time. I can arrange a portkey and we should leave now." Athena told Klaus whose eyes narrowed and his jaw clenched angrily.

"Why would I save someone who killed my brother? They're still alive only because I promised you that I won't kill them. What happens to them isn't my problem." Klaus almost growled.

Athena shook her head miserably and looked at him again. "I know that you've done more for me than anyone else I've ever known and I cannot thank you enough for that. But you have to help them. They're in this situation because of me. I don't want another name to add to the list of people who've died because of me. Please! Please! I'll tell you everything you want to know. Just please don't let them die. I'm begging you. Just, please…!" her voice cracked at the end as she looked at Klaus beseechingly.

Klaus was about to say no, that he didn't care what happened to these people, but one look at her wide eyes which were filled with anguish and looking at him with such hope, that he found himself agreeing to whatever she had said unintentionally. Emerald eyes which reminded him of the first woman who didn't treat him like a monster he was, his only best friend. Face which made him look like he was looking at a feminine version of himself – a perfect combination of Lily and himself. He nodded at her which earned him a blinding smile from his daughter and he sighed. What was it that he, the most terrifying monster found himself doing whatever she asked, just to make her happy?

Kol and Stefan looked just as shocked as felt himself, but he ignored them and focused on his daughter, who was now hugging him like there was no tomorrow and he found himself hugging her back and that giving the cure was probably worth it.

Salvatore Boarding House

Mystic Falls

"There must be something. We cannot let them die, Bonnie." Elena muttered as she looked at her friend desperately.

Bonnie shook her head and told her sadly, "I've searched everything. I've read Emily and my gram's grimoire, but there's nothing. It's Caroline, Elena. I don't want anything to happen to her."

Elena nodded but said, "Things didn't turn this bad when Tyler bit Damon. It took a couple of days and he was bitten just yesterday. You've seen that he's already delirious. If Alaric hadn't reached here in time…" she couldn't complete her sentence as she shivered at the recent memory.

.

.

She received a call from Elijah this morning, that she was needed at the Boarding house and it was urgent. She had told Alaric about the call, who was at school and had told her that he would be there at the Salvatore's as soon as he can. She tried calling Caroline but she didn't pick her phone. The first thing she saw when she entered was Damon passed out on the couch. He was pale and sweating, just like she remembered the last time he was dying in her arms. He was burning up, but didn't wake when she touched his forehead. That's when she heard sounds from the basement and frowned. Stefan wasn't here, so it could only be Elijah, but what was the original doing here? She went downstairs and stopped short in horror when her eyes fell on Caroline. Several blood bags were littered around the room which were empty, while Caroline was busy scratching her shoulder. It looked inflamed and was bleeding badly.

Elena sucked in a harsh breath and gasped when Caroline's head snapped up. She had blood all over her face, in her hair and even down her dress. She stopped scratching her back as soon as she saw Elena and cried, "They're not healing! Please, help me! I don't wanna die, Elena."

"Nothing's going to happen to you. We'll find something." She told Caroline firmly, even though she had no idea what had happened to the two vampires, but it was clear that her friend was in no condition to tell her. Suddenly, a thought hit her and she murmured, "Have you tried to drink blood straight from the vein? Maybe it'll help."

At the suggestion, Caroline's fangs descended, veins appeared under her eyes and Elena's eyes widened at the hungry look in her friend's eyes. "I'm sorry, Elena, but I don't want to die." With that, Caroline blurred towards Elena, but before she could attack the other girl, two hands snapped her neck and she fell to the ground.

"Elijah!" Elena breathed, relieved. "What happened?"

"I don't know what's happening to Miss. Forbes. She wasn't bitten, but she isn't healing, unlike Damon." Elijah told Elena as he picked Caroline up and locked her inside the cellar.

"What?!" Elena asked panicked.

Elijah turned towards the girl and mused, "Damon was bitten by a werewolf, but he's showing the symptoms which normally take two-three days to make a vampire delirious, much earlier than they should've. Maybe because it was a different werewolf." Then he looked at Elena's horrified expressions but said, "I haven't had the clue as to why Miss. Forbes isn't healing. A scratch from even from a werewolf isn't life-threatening to a vampire."

"Who attacked them?" she asked.

"Greyback wasn't someone we knew. All you need to know is that he's been taken care of. Miss. Forbes is… fine for now. Its Damon you should be worried about. He doesn't look… good." Elijah finished indifferently.

She looked him in the eyes and muttered quietly, "Klaus can save them."

Elijah raised a disbelieving eyebrow at her. She was asking for the cure when only days back, she was trying to kill every Mikaelson along with her friends. He trusted her and she had deceived him by plotting to kill them with their mother. "Niklaus isn't in the country."

"Please! I'll do anything if he saves them." She begged.

Elijah shook his head sadly. As far as he knew his brother, Niklaus would be more than happy to see the Salvatore's die. "I'm truly sorry, but I cannot help you."

With that being said, he decided to take his leave, ignoring the devastating expressions that crossed the doppelgänger's face. He had matters to attend and even though he was curious to know how things were affecting the two vampires, they weren't important. He wanted to know why the wolf was after his niece and how many more people were after her! He needed to contact Kol or Niklaus, who wouldn't be happy. Which was the reason he called the doppelgänger. She was closer to the vampires and would handle them along with her friends.

Elena looked at Caroline through the bars, who was still lying on the ground, unconscious and decided that Damon needed someone more than anyone right now. She turned to leave, but blinked when she heard a ringtone and realized that it was Caroline's phone. She was thankful that it was Stefan and she told him everything Elijah had told her, who told her that he'll be back soon and to take care of Damon.

She went upstairs and stopped short. Damon wasn't there on the couch where he had been before she went downstairs.

"Damon?" she called tentatively. The last time they had met, he had tried to kill her. Elena didn't know how he would behave as he has always been unpredictable and eccentric. She just hoped that he won't attack her again.

"Damon?" There was no response, so she went towards the stairs and called again.

The hair on her back stood as she felt the wind, but there was no one when she turned around and she gulped.

"Katherine!" the name was a whispered plea and she whirled around. Damon was looking at her like she was the eight wonder of the world. She knew that expression. Had seen it on his face when they were exactly in the same situation before. When he hallucinated about Katherine last time. It seemed like the same thing was happening all over again. He staggered towards her and fell on her as she struggled to keep him upright. He was breathing her neck while whispering Katherine's name again.

"Damon, it me, Elena." She told him and he pulled back, blinked several times and shook his head as if coming out of a trance.

"Elena?" he asked as he pulled father back from her.

"Yeah. Stefan is coming home and we'll find a cure for you." She told him firmly. He was pale and sweating as he stared at her.

"YOU! You did this! It's all your fault." He told her quietly and Elena was sure that he was crying.

She frowned and asked, "What…?" but before she could finish, he whispered in an anguished voice, "I deserve this and even more."

She moved towards him and said again, "Damon?"

His head snapped up and his eyes bled with red and he shouted, "She's gone because of you!" with that, he attacked her. Her head collided with wall at the same time his fangs pierced her neck and she screamed.

"Damon! Stop! You're hurting me!" she begged desperately as she tried to push him to no avail, instead he started drinking more vigorously.

Just as it had started, the pain stopped as Damon pulled back and turned around, only for Alaric to stab him with more vervain. Damon fell as Elena's hand went to the wound on her throat and she looked up to see Rick looking at her with concern.

.

.

They had chained Damon inside his room because locking him in the cellar with Caroline couldn't do any good. God knows what they might do to each-other in the state they were in. She, Bonnie, Alaric and Jeremy were sitting in the parlour, listening to Caroline's anguished screams for help, while Damon was still out. They've refrained from going near Damon, but it was decided that Alaric and Bonnie would be the one to help him once he woke up. Klaus wasn't here and they had no idea what to do.

Suddenly, Bonnie felt strong magic in the air and her brows knitted together, not understanding what it was, but whatever it was, it had her on edge. She stood up, looking around. Elena was about to ask what it was when they saw blue light shimmering in the air and the next thing they knew, there were four people in the living room beside them – well, three were lying on the ground, while Athena was standing, but still.

"What?" The one's present there gaped, bewildered.

"How did you do that?" Bonnie asked Athena as she looked at the witch with narrow eyes.

"It's a portkey. It allows us to instantly teleport anywhere we want." Athena answered as she looked at Bonnie, showing her the utensil, she was holding, even though her focus was solely on finding Damon and giving him the cure.

"Damon and Caroline?" Stefan asked urgently.

"Caroline's in the cellar and we had to lock Damon in his room after he attacked Elena." Alaric answered as he looked from Stefan to the Originals to the Witch.

Elena looked at the four in front of her and her heart constricted when she realized that Stefan was with Athena and she had convinced her father to come here. She pushed that thought aside for the time being for the more important issues that needed their attention. Even though she knew, but she still had to ask, just to make sure or why else would Klaus be here? In case he demanded something in return, she would willingly give him anything he wanted. Caroline was her best friend and she loved Damon, and couldn't see him in such agony, even if he hated her now. She knew that he loved her still and couldn't stay angry at her for long. She'll make sure to apologize to both, once Damon was fine again. She took a step towards the hybrid and asked, "Are you here to give them the cure?"

"It's marvellous, isn't it? Not days ago, you were trying to kill me and now here we are!" Klaus replied with a smirk as he took a step towards the doppelgänger, but the Bennet Witch stepped in front of her friend and glared at him threateningly.

Athena stepped in front of her father and said in a placating manner, "We're not here to fight. This isn't the time."

Then she turned towards Klaus who threw a glass vial at Bonnie, which was filled with his blood and said, "The cure for your blonde friend."

Bonnie nodded and moved to go to the basement when Elena stopped her and asked, "What about Damon?"

Stefan showed her another vial and replied, "I have it."

Elena looked him into the eyes and nodded before going downstairs with Bonnie, while Stefan went to Damon's room and Athena followed. Klaus wasn't about to let her go in front of a rouge vampire alone, so he went as well. The door was locked, but Stefan hurriedly opened it before entering inside with Athena hot on his heels.

Emotions spilled out when she saw the condition Damon was in and she sucked in a harsh breath. He was pale, gaunt and was sweating buckets. His hands were tied to the bed and he wasn't even trying to free himself, but he looked up when he heard the sound of the door opening. His eyes were hazy and bleary, and to her it seemed like there was no recognition in them. He wasn't wearing a shirt and the bite was visible to everyone and she shuddered when she looked at it. Greyback had managed to tear a piece from his shoulder and it hadn't grown back like it should have.

"Damon!" Stefan breathed as he looked at his brother. He was even in worse condition than the last time and he felt a wave of grief hitting him at the realization that he could've lost his brother today if he hadn't made that phone call.

He moved at Damon's side and touched his brother's hair. "I've got the cure. You'll be fine, brother." Stefan whispered through the lump in his throat.

"Mother." Damon murmured looking around and Athena felt tears filling her eyes. This man seemed so lost and looked nothing like the person she had come to know or the murderer who killed her friend so ruthlessly in front of her.

Stefan corked the bottle open and poured it all down Damon's throat slowly. He wasn't going to take any chances. Once it was done, he sighed, waiting for the cure to work and sat beside his brother. He looked at Athena, who was focused only on Damon; while Klaus was standing beside her looking curious.

Damon blinked after a couple of minutes and looked around. "Brother?" he croaked as soon as his eyes landed on Stefan.

Stefan, Athena and Klaus noticed that even though Damon recognized Stefan, but the wound wasn't healing. Stefan turned to look at Klaus who was looking at the angry bite with nothing but frustration.

Elena entered the room, unbeknownst of the tension in the room and said, "Caroline's fine. Her wounds are healed. She's still a bit out of it, but she'll be fine."

Athena couldn't control herself after hearing that Caroline was fine and asked, "Why isn't it healing?"

"I don't know. It should've…" Klaus mumbled perplexed.

Elena's eyes widened, horrified with the realization that Damon hasn't healed yet. "Did you give him the cure? But last time the cure worked as soon as he drank it." She told them.

"Maybe he needs more? It was a different species. It would make sense." Stefan said unwilling to believe that the cure wasn't working on his brother.

It bemused Klaus to no end. His blood was the only cure known to heal vampires from the werewolf bite. If it had worked on the girl, why wasn't it working on Damon? So, he moved towards bed without any prompt and settled beside the older Salvatore. He bit his wrist before placing it on Damon's mouth, who latched onto it instantly. Klaus pulled his hand back once the vampire had enough and they all waited for something, anything to happen. He didn't seem to be in a daze anymore and his heartbeat seemed normal for now. But other than slight change in his colour and drop in his temperature, there was no change in his condition.

Stefan and Athena shared a look, conveying their emotions without words, not knowing what to do, but both reluctant to admit what they knew in their hearts.

They didn't have the time, neither did they have the knowledge of another existing cure. Damon was going to die without the cure and there was nothing they could do about it. Klaus's blood had given them time, but the question remained, how much?

AN: It's a bit short, but I'll try to update early this time. Hope you liked it. I would like to hear from you, even if you didn't or if you feel that something's missing. Positive criticism is always welcome.

Have a nice day everyone!
