For several moments, Klaus just stood staring at the fallen photo displaying the face of his little girl. His hands were shaking from it. It had been many years since he'd seen his daughter's face, other than when he closed his eyes. Any photos he had were lost when he had to flee New Orleans from Mikael, which he considered just as well. It was too painful for him to look at them anyway.

Elijah bent down and picked up the fallen photo from the broken frame it sat in. He stared at it in shock. It was his niece, or at least it looked like her. It couldn't be here, but it was literally identical to her. Yet, Jenna had said this was Elena. That could only mean one thing. Sadie was a Petrova doppelganger, and they'd never known it.

Klaus' shock and uneasiness turned to rage, and he glared at Jenna Sommers. "How did you do this? Where did you get a picture of my daughter?"

"That's not your daughter, Klaus. That's my niece," Jenna said.

"That is my daughter! I know my own child! I have not forgotten one detail of her face, and it is identical to that child!" Klaus yelled.

"She was a doppelganger, Niklaus, like Elena and like Katerina," Elijah told him. He was holding proof in his hands. This child wasn't his niece. It was a fairly recent photo, taken no more than ten years prior, and the people in it were Elena's parents.

"That's not… No, that's not true. She couldn't be," Klaus said as he shook his head. Fate couldn't possibly be that cruel, could it? Who was he kidding? Of course, it could. In fact, it probably got a good laugh at his expense, knowing that the one person who could end his curse was his own daughter. If he had wanted his curse removed, he would've had to sacrifice his own child. Not that he ever would. The curse be damned. He would live forever with it rather than harm a hair on his daughter's head. It didn't end up mattering though. His daughter was dead, long before he could've even learned that she was a doppelganger.

After a few moments, Klaus glared at Jenna again. "What do you hope to gain by telling me this. My daughter is dead. This doesn't change that. What, do you think that knowing your niece looks just like her will make me leave her alone?"

"My niece is dead," Jenna said bluntly.

"What? When?" Elijah asked in shock. That saddened him very much. He had not wanted that young girl to die. That was why he'd planned to give her the elixir and why he'd ushered his brother out of town when the sacrifice failed.

"It's not what you think. She's been dead for a while. She was killed two years ago by Stefan Salvatore. Neither of you ever met her," Jenna said sadly. Elena's death was still very raw for her. She and Jeremy would probably never stop grieving. It was made worse by the fact that they couldn't even bury her or hold a funeral for her.

"What nonsense are you spewing? The girl was obviously quite alive three months ago," Klaus said.

"No, a girl with her face was alive. A girl who turned into a werewolf before your eyes and mine, which doesn't run in my niece's bloodline, but it does in yours," Jenna said pointedly.

Klaus' eyes narrowed and darkened at her words. He could figure out what she was attempting to imply, and he would literally tear her apart for it. "Don't you dare! I will see your head in my hands!"

Elijah grabbed his brother just as he was about to attack the young vampire. "Jenna, you need to speak quickly and clearly."

Jenna shuddered. She knew her life was on the line here, but she was going to risk it anyway. As much as she couldn't stand Klaus, he deserved to know the truth. No father deserved to go on believing that his child was dead. "Things changed after that first full moon. It wasn't just turning into a werewolf. Things were happening to her. She was remembering things that had never happened, from a time that she shouldn't have been alive to see. She thought she was losing her mind at first."

"You spew lies!" Klaus snarled as he attempted to attack her again.

Elijah held his brother firmly. It was taking very bit of strength he had, and he knew he wouldn't be able to hold him for long. And if he found out Jenna was lying about what she was insinuating, he would help his brother rip her apart. "What did she remember?"

"At first, not much concrete. It was just a bunch of flashes. They were so intense they wouldn't' leave her alone. She also felt differently about certain people, like Stefan. She described the whole thing as her mind being rewritten. What she didn't realize was that her mind had already been rewritten. It was correcting itself," Jenna explained.

"Compulsion," Elijah said. That was what it sounded like. Like most supernatural creatures, werewolves couldn't be compelled. The moment they shifted, any compulsions that existed would break.

Jenna nodded. "Bonnie called her cousin, a witch. She told us that what was happening to Elena was compulsion. She also told us that was immortal and had been alive for a long time and had stop aging."

"No!" Klaus snarled. This wasn't true. It couldn't be. His daughter was dead. He'd seen the building she was in explode. There was nothing left.

"Keep going, Jenna, and let me warn you that if you are lying, you death will be slow and merciless," Elijah said in cool tone.

"Don't threaten her," Jeremy said.

"It's okay, Jeremy. I can understand how they feel," Jenna said before addressing Elijah and Klaus once more. "The next day, Elena and her friends went to confront the Salvatore's. Stefan was gone, but Damon was dying from a werewolf bite. He told them everything he knew. I guess he figured he had nothing to lose."

"What did he tell her?" Elijah asked.

"That in 1914, Stefan and Katherine abducted her from her home, from your home," Jenna said.

Klaus' eyes widened slightly. "Katerina?"

"Yes. Katerina Petrova kidnapped your daughter, with the help of her little boytoy," Jenna said with a sneer.

"Let me go, Elijah," Klaus demanded. He was prepared to listen now, but he was still very reluctant to believe any of this.

Reluctantly, Elijah did so.

"Katherine kidnapped your daughter to get back at you for killing her family. Then she killed my sister to put your daughter in her place," Jeremy said as he glared at Klaus.

"Jeremy, you can hate him for what he's done, but what happened to Elena isn't his fault," Jenna said. She refused to blame anyone other than Katherine and Stefan for what happened to Elena. Blaming anyone else took the blame from where it truly belonged. Klaus was a horrible person, but he didn't deserve what happened to him.

"Tell us the rest, Jenna," Elijah said.

"There's a lot of gaps. Damon didn't seem to know everything either. He claimed he didn't become involved until after your niece was compelled to be mine," Jenna said.

"My daughter couldn't be compelled. She was a witch," Klaus said.

"I know. Her magic was apparently blocked," Jenna said.

"An answer for everything, huh, love?" Klaus asked with a sneer.

Jenna decided not to respond to his skepticism. She just continued the story. "Klaus, the night of the sacrifice was organized for years, but not by you. Katherine had set it up. She wanted you to kill your own daughter. A wrench was put into her plan by her own accomplice when Stefan compelled Elena to dagger Elijah."

"She was compelled to do that?" Elijah asked surprised. He hadn't known that. She didn't seem like she was compelled, but it often happened that way. Sometimes it wasn't evident until it was too late.

"She was compelled to do basically everything. She was compelled to be Elena. She was compelled to forget everything she knew, probably over and over again. I'm not sure where she ended and the compulsions began," Jenna said sadly.

"What you expect me believe is that the child I grieved for has been mentally tortured for decades upon decades with no one there to protect her from it? You expect me to accept that?" Klaus asked with grief and anger in his voice. Accepting Sadie's death had never destroyed him, but he found a small degree of solace in the fact that she wasn't in pain. Now he was being told that she'd likely known nothing but pain and torment for almost a century.

"I'm sorry, Klaus. I truly am. What happened to her, what happened to you, it's awful. They're monsters," Jenna said. She knew no other word to describe those people. They had destroyed countless lives in their wake. They had wrecked at least two families, and they had destroyed that little girl's innocence.

"Why should I believe you?" Klaus asked.

"I think you do believe me, Klaus. I think deep down, a part of you already knew. You said it yourself, you know your own daughter," Jenna said.

Klaus wanted to deny it, but he couldn't. From the moment he laid eyes on the girl, something didn't seem right. Sacrificing her felt wrong, but he shoved that thought down, and he was still prepared to do it. Then she started to become a werewolf, and he felt the need to help her with it. He wouldn't leave her side until she completed the change, and he couldn't figure out why that was. He couldn't figure out what it was about the girl that made him not want to hurt her. But how was he supposed to accept it? If it was true, he'd nearly killed his little girl?

"Niklaus, we never found a body, and Katerina is smart enough to pull something like this off. She's a werewolf. That never made sense with Elena Gilbert's bloodline," Elijah said.

Klaus screwed his eyes shut. This was his little girl. He'd failed his little girl completely. He'd given up, and she'd suffered a fate worse than death. How often must she have cried for him, begged for him to save her, and he hadn't even been looking. How could he not have been looking? How could he even have given up without definitive proof? All they'd found was a necklace that Rebekah had given to her. That wasn't proof. Why did he give up?

Elijah saw the look on his brother's face. He knew Niklaus believed, even if it was destroying him. However, there were other questions to be asked, and it was clear that his brother was in no condition to ask them. "Is that all you know, Jenna?"

"Yes, that's all Elena knew," Jenna said. Well, that wasn't entirely accurate. There was more she wasn't telling them, like what Stefan had done to Elena, but that wasn't her place. It was up to Elena to tell her family that Stefan raped her when and if she was ready.

Klaus' eyes popped open. "Do not call her that! My daughter's name is Sadie. Where is she?"

"She left a couple of months ago. She couldn't stay. She said she had to figure out who she was and couldn't do that in a town where everyone believed she was Elena Gilbert. She also wanted to give us the chance to grieve," Jenna explained.

"You let her go off alone?!" Klaus asked furiously.

"No, she's not alone. Bonnie and Caroline went with her. I didn't want her to go, but I couldn't make her stay. She was right. She couldn't figure out who she was here," Jenna said.

"You don't know where she is?" Elijah asked.

"No. I haven't talked to her since she left. Jeremy, you're in contact with Bonnie, right?" Jenna asked.

"Not since they left. I've been going out of my way not to talk to any of them. I can try to call her in the morning. It's getting pretty late now," Jeremy said.

Klaus couldn't take it anymore. He needed to get out of there before he exploded with rage and pain. So, he did. He walked out without another word.

Elijah let his brother go. He knew that Niklaus needed time to come to terms with this. Unfortunately, that probably meant blood would be shed. Instead, he turned back to Jenna. "I'm very sorry about your niece, Jenna. I'm sorry she was caught up in this. Thank you for loving mine."

"I wish I could've helped her," Jenna said sadly.

"I believe that you did. No matter what else, there was at least a two-year period where she knew something besides pain, and that is at least partially because of you and your family. I will never be able to thank you enough for that," Elijah said.

"Take care of her. That's the only thanks I ask. She may not be my niece, but I love her as though she is," she said.

"You have my word," Elijah said before reaching into his pocket and pulling out a card. "This is my number. Call me if you're able to locate my niece."

Jenna nodded and took the card. "Good luck, Elijah."

Elijah gave a curt nod before turning and walking out the door. He had a look of determination on his face. Once his brother finished his meltdown, they would find Sadie. Then they would make the people who harmed her beg for death, and they would be denied that mercy for as long as possible.
