I will be loosely following the TVD storyline. There will definitely be some changes.
She ran into the house as she heard Damon scream holding onto the hem of her dress to make it easier to run. Her father took everything out on her oldest brother. Damon usually took the blame for Stefan to spare him. Samantha was the rose caught between two thorns as her mother would say. Damon was older by 4 years, Stefan by 3. Giuseppe had never raised a hand to her and barely ever his voice. But even at the young age of 10 Samantha knew how to assuage her father. It was a talent.
She entered the room as her father back handed Damon. She cried out in horror as she saw blood spilling from Damon's face.
"Papa no more!" She yelled as tears fell from her eyes. She ran to Damon, dropping to the floor to comfort him.
"Samantha you stay out of this!" Giuseppe roared. "Damon will take responsibility for his actions"
"I think he's taken enough responsibility don't you?" She looked at Damon. "Go to my room. I will clean you up." She glared at her mother who did nothing. Samantha saw her as nothing but weak and pathetic. She rushed over to her father and grasped his hands. "Papa please. You know how your and Damon's fighting upsets me so. I hate to see him hurt. And I hate to see you so angry. Please. Please let it go. I will talk with him. But no more violence please. I can't take it." She amped up the water works and the pleading eyes. "Damon is stubborn and proud. Just like you are. Don't beat that out of him or he'll never become the man that you have grown to be." She could barely stomach it. But she found it to be her job to save her brother. Someone had to."
She watched as Guiseppe softened. She let out a small sigh of relief. "I'm sorry Darling you're right as always." He placed his hand on the side of her face. "I fear your dress has been ruined by Damon's blood. We'll get you a new one"
"Nonsense. I'll go clean Damon up and I'm sure mother would be more than happy to get it cleaned for me. She can scrub it out. No sense wasting it." She smiled at her father and turned to go find Damon. She shot her mother daggers as she walked by her. Stefan was hiding behind the doorway eyes wide from what just happened. She kissed his forehead and whispered in his ear to clear out. Another crises adverted for now.
Samantha sighed as she thought about that horrible afternoon. She had held Damon as he cried from pain. They had made it their mission in life to protect Stefan. Oh how they had failed him. She left flowers at her father's grave. She could never quite come to terms with the man who had so much love for her and so much contempt for Damon. She held the most contempt for her mother, even after all this time. She stood by and did nothing as her husband brutalized her own children. Lily had little love to show her daughter. Maybe that was her way of making up for it. Guiseppe had loved her most, so she had decided to show her very little love at all to even things out. Samantha didn't bother visiting her mother's resting place. She couldn't bring herself to do it.
She hopped into the white Jeep she had compelled for herself and made her way to the boarding house. It was time to long at last reunite with her brothers. And she desperately needed to investigate the newest Doppelgänger and then find Katerina. She had a score to settle and this time she had an ace in her pocket. She had secrets of her own, things even her brothers didn't know. She planned on keeping them to herself for now. Not that she wanted to keep them in the dark; in fact she didn't like keeping anything from them. Yet she knew she would need to use any advantage she had in the near future and the element of surprise would only help her.
Samantha opened the door of the boarding house and closed it quietly behind her. She heard Stefan's raised voice and what she assumed was The Doppelgänger's voice. She stood listening for a moment to try and get a grasp on what she was about to walk into. She had lied to Stefan about something. Apparently something "dangerous". She walked towards the living room. She smirked as Elena stared at her. She knew by looking at her she was the third Salvatore.
Her long curly hair was the same as Stefan's. But that wasn't it. It was the ice blue eyes and smirk that graced Damon's face on a daily basis. She was small in stature, petite features. But the confidence that radiated from her made her seem like a giant. Elena couldn't get over how beautiful she was.
"Please don't stop on my account." The first sound of her voice and Stefan had spun around. A look of confusion and elation graced his face.
"Sam- what are you doing here?!" Stefan rushed over and embraced her. "God I missed you." She slowly pulled away from her brother and took a few steps towards Elena sizing her up.
"This is why I'm here." She circled around Elena who stood awkwardly. "Rumors of another Doppelgänger clearly we're not exaggerated. I mean it's uncanny." Stefan started to speak but she held her hand up to silence him. "Now, I also know about Katherine. How she lied and wasn't underneath that church. I can only imagine the affect on Damon. I also know the affect this face has on my brothers. So let me say this, I am not willing to stand by as a Katherine 2.0 puts herself between my siblings. And while I understand that you have no control over how Damon feels and I can imagine his feelings for the Katherine that he thought he knew may be transferring to you. But let me make myself perfectly clear if you even for a moment pin my brothers against eachother for your affections, the dangers that you're facing right now will seem like child's play."
"Sam this isn't necessary." Stefan started to argue.
"But it is. I won't stand by and watch what happened before happen again. I know what's been going on since the two of you came back home."
"How?"
"I have informants. Just because we parted ways since your last binge doesn't mean I stopped caring about you Stefan and stopped looking out for you. You're my brother. You're my family. I swore to you I would always look out for you."
"What made you part ways with Damon?" Elena asked.
Samantha looked at her. "His obsession with Katherine. It was too much. And I I needed to live my life." She sighed.
"You said I was in danger."
"You've been told about it I'm sure. I know you were snagged after a masquerade ball. The stories you've been told about Niklaus are very real and true. He will come for you."
"Katherine wasn't lying?"
"No. I'm sure anything she told you is the truth."
"Elijah tried to take her. Damon killed him." Stefan watched his sister stiffen.
"Did he now? And where is my beloved older brother?"
"I'm not sure- why?"
"I have a feeling he's in for a nasty surprise sooner rather than later."
"What do you know?" Elena questioned.
"I know everything. I know every single thing that you want to know, but I can't tell you. Not that I don't want to tell you, I physically can't."
"And why not?" Stefan demanded of his sister.
"Because dear brother a vampire can be compelled by an Original. I've been compelled to not tell what I know. I can't write it or speak it or communicate it in any way."
"You know The Originals?!" Stefan was shocked.
"Yes"
"Do you know Klaus?" Elena's question was almost a whisper.
"Yes. I knew him. It's been a very very long time since I saw him. But the stories are true. And that's why I'm here. To make sure my brothers don't die in the crossfire. Elena as of right now I have no quarrel with you. But make no mistake I will do anything to protect my family even if it puts you in harms way. Now- where can I find Katherine." Stefan stared at his sister in disbelief. What else was she hiding? He knew pushing her would get him nowhere. He'd have to do some digging of his own.
"Here Kitty kitty kitty" Samantha called into the tomb. She heard shuffling and waited for Katherine to show her face.
"Well well well- the prodigal sister returns home." Her hoarse voice called as she made her way to the entrance.
"Hello Katerina." Samantha crossed her arms.
"So much contempt for me. Shouldn't you be thanking me? You've become this powerful woman. I even heard stories about you while on the run. I mean your love story alone-"
"Shut up. I have nothing to thank you for. You didn't make me who I am. You may have had your part in turning me but that's where your influence ends Katerina. If I'm strong it's because I was always strong and have worked to be the woman that I am. I've spent 145 years to try and fix what you broke. And seeing you in all of your splendor now is oddly rewarding. And when Niklaus comes...and we both know that he will come, I look forward to watching him tear you apart."
Samantha turned and was about to walk away.
"How is he?" Samantha turned back around.
"Don't." She warned.
"I was just curious." There was a taunting tone in her voice. Samantha shot her a glare and pulled a blood bag out of her coat.
"I was going to give this to you, but since you're a bitch as always..." Katherine fought against the invisible barrier as Samantha poured the blood onto the dirt floor. "Toodles Kat" and in a flash she was gone.
"Sammy!" She turned as she heard Damon's voice she ran and jumped into her big brother's arms. He cradled the back of her head as he hugged her. "I missed you so much. When Stefan texted me that you were home I didn't believe him."
"So you guys are talking. That's good." She gave him a genuine smile. Their relationship was never strained line hers and Stefan's. But Damon had never hurt her the way Stefan had. Damon squeezed her again before letting her go.
"Don't take this the wrong way, but why are you here? You said you'd never step foot in Mystic Falls again." They sat down on the couch in the office.
"Well I heard about the Doppelgänger and that you were both here so I had to come. I had to make sure you didn't destroy eachother."
"She's bit like that."
"We shall see. And she doesn't have to be like her to have the two of you tearing eachother apart."
"We're fine. We've been working well together'actually. You'd be proud."
"Mmmm. Damon I know you. And I know what Katherine did to you. And you can't tell me that you don't have feelings for Elena."
"It doesn't matter what I feel. It will always be Stefan for her." She heard the bitter tone in his voice.
"Damon you deserve someone that loves you and only you. Don't pine after your brother's girlfriend." Damon was about to respond when a woman walked in.
"Sammy this is Rose. Rose this is my sister."
"She's the one that took Elena to Elijah and she's here?" Samantha asked with a raised eyebrow.
"Well to be fair she came to help us after Elijah killed her friend...and then I killed Elijah."
"I see. Well, I'll leave you two alone. Damon we'll catch up tomorrow." She patted his knee and the stood up and walked out of the room and straight out of the house wishing she could tell her brother what she knew.
A while later she found herself standing on Wickery Bridge looking out at the water as she felt someone approaching. Her breath hitched in her throat knowing it was him. She didn't have to even look to him as he stood next to her and had placed his hand over hers. Her whole body felt like it was on fire even from the slightest touch from him. All she could think about after all of this time was his lips on hers. The feel of his skin against hers. His fangs into her neck.
"Hello Darling. It's been a very long time" He whispered into her ear. He was standing behind her now, close to her body but not close enough for her liking. He was never close enough. Her heart ached for him. This was why she had stayed away. Because no matter what was hapoening, no matter what he had done in the name of his brother she loved him. She would forever be I love with him.
"Hello Elijah" she slowly turned around so she could see his face. As always he towered over her. But she wasn't afraid of him. She was never afraid of him. She knew he would do anything to protect her. She looked deep into his eyes. She knew she missed him, she just didn't realize how much. And she knew loving him was now a betrayal to her brothers- but she didn't care. She couldn't care. Before she could say anything else, his hand was tangled into her curly dirty blonde hair and his lips were crashing against hers.
