AUTHOR'S NOTE: For those of you who don't follow me on Tumblr, on Thursday I posted a message asking people if they'd rather I posted on Friday or Sunday and the votes were equal so I decided to post in the middle.

The response I got over the last part and its cliffhanger were amazing. I love reading everyone's theories. All of my readers have been amazing whether they leave a review, follow or just favorite, I thank you all.

As of right now, I will not post again until next Sunday. I've had a week from hell and have not written hardly anything, which is very rare for me so I'm severely lacking in parts. I'll try to remedy that soon though.

Part 15

"Because I caught her in bed with my brother." Klaus declared before taking another drink from his tumbler.

As she started to choke on the Scotch, Caroline was very glad she hadn't taken a larger drink. She hadn't been expecting the answer he had given her. The Mikaelson men all seemed so close that she couldn't imagine one of them sleeping with their brother's wife. Hell, two of them had wives of their own, which left only one possibility in Caroline's mind. "Kol?"

"No, it was Elijah," Klaus answered, not bothering to ask why she had thought that it had been Kol who he had caught with Tatia.

"Elijah cheated on Katherine?" Caroline asked not believing what he said for two reasons. One, because the idea of Elijah cheating on his wife or betraying his brother like that didn't mesh with the gentleman she had met at Lexi's meet. And two, she was pretty sure Katherine would have done serious physical harm to him that would have made Daniel and her current pregnancy impossible.

"Sorry, I'm not telling this right. I've never talked to anyone about it so my story telling skills are a bit rusty," Klaus clarified. He knew if he were going to tell her his history with his ex-wife, it would be best to start at the beginning otherwise things would get even more confusing than they already were. It had been a long time since he had dredged up these memories; he tried to keep them buried. If he didn't, they would drive him insane.

"I met Tatia when Elijah and I were still at University. Unbeknownst to me, she had also met Elijah at the time and we both began to pursuing her. Once we did find out about each, we told her she would have to choose. She said she couldn't because she cared about both of us. We were in the middle of forcing her to make the decision when Elijah's attentions were directed elsewhere. Katherine came to school to visit her twin and she and Elijah hit it off. Tatia chose me, which according to her she'd been planning to do and things went from there. By the time I got my degree, we had been involved for a few years and I did what I thought was the next logical step and convinced her that we should get married."

"Convinced?"

"I had to talk her into it. She said that she loved me but was hesitant because she didn't think we wanted the same things," Klaus clarified. "She didn't want to have children and she knew that I did. Growing up in a big family, she knew I wanted to have one as well."

"I thought it was something that she would change her mind about after a few years. Her and Katherine's parents died in a car accident when they were sixteen, so it was just the two of them after. I thought she would want to fill the void left by their death with a family. I told her it was fine that she didn't want kids. She ended up saying yes and we got married, couple years later she was pregnant."

"I'm guessing that she still hadn't changed her mind?" Caroline asked when he paused in his tale to take another gulp of his drink.

He shook his head in reply. "No. She was still adamant about her choice while my desire had grown; substantially so."

"Tatia wasn't completely indifferent to being pregnant. She didn't want to have children, but she never said a word about not having them and she took care of herself. The women in her family have difficult pregnancies—you've seen that with Katherine—but Tatia did everything she was supposed to. I took it as a sign that she had warmed up to the idea by the time they were born," Klaus explained. "But I was wrong."

"Not long after Henry and Lexi were born, I realized that the connection between Tatia and I had started to deteriorate even more than I had thought. I was busy trying to help with the business but also be at home to help her with the babies, most of the time I fell asleep on the bed in the nursery and she felt neglected. We started fighting constantly."

"Katherine and Elijah knew the issues we were having, and tried to help. They thought that maybe some time away from work would do us good but knew that the twins were too young for us to leave them. So they rented this house on AmityIsland and went with us. They helped with the babies and even watched them one night so we could go out for dinner on the beach. That night didn't go as planned and we ended up arguing," Klaus recounted as his mind drifted.

"Later that night, I was out on the beach with Katherine just talking after everyone had gone to bed. She was trying to calm me down while Tatia was inside. Evidently, during this time, she came to the decision that she had married the wrong brother. She went into Katherine and Elijah's room and crawled into bed with him. Katherine and I came back into the house, earlier it seemed than Tatia was expecting and caught them. They hadn't gotten very far but it was evident what was going on."

"I still can't believe that Elijah would do that."

"He didn't actually. He had been asleep when Tatia came in, and in his sleep induced daze, he thought she was Katherine. They are twins after all, identical and it isn't much of a stretch when you are half-asleep. She and I could tell he was telling the truth, but Tatia wasn't innocent." Klaus rose from the couch then and moved over by the fireplace. As he did, he began to pace. Recalling that time was bringing back a lot of the anger he had felt that night and he needed to release it in some way.

"I was furious—beyond furious. Back then, I didn't have much of a grip on my temper and I lashed out at her. I didn't strike her. No, we always used words to hurt each other," Klaus explained when he saw Caroline's eyebrows go up in question. "We were so loud that we woke the twins."

"Their cries brought me out of the rage I was in; I went in and settled them down. I chose to sleep on the floor that night; I couldn't stand the thought of sleeping in the same bed as her again. Not after her betrayal," Klaus justified. "We went home the next day. When we got there, I told her that I would never share a bed with her again. We would be legally divorced but we would live together and raise the kids. I didn't want them to live in separate houses. She left two days later."

"What did she say when she left?" Caroline asked.

"Nothing; I wasn't there when she left," Klaus answered. "I came home from work—we still lived in a small apartment while we looked for another place—and it was empty. At first, I thought she might have just taken the twins out, but there was no note or message from her. Then I noticed that some of her stuff was missing. I checked her closet and all of her clothes and some of the kids' stuff was gone."

"I panicked. I thought she had taken the kids and left," he said, trying not to choke as the fear he remembered from that day came back to him. "I called Katherine, but she hadn't heard from her sister. I was just about to call the police when Sage called me. She wanted to know what time I was picking up the babies."

"So she didn't take off with them?"

Klaus shook his head. "Tatia had called Sage earlier and asked if she could leave the twins with her for a little bit until I got off work. I don't remember anything from the time she told me that until I got to her and Finn's place and saw them with my own eyes."

"You had to have been terrified," Caroline remarked. She understood a little better now why Klaus was so protective of his kids. He had first-hand experience with the terror a parent felt when their child was missing or lost. In his case, he had thought that someone he had trusted had ran off with them, possibly just to hurt him.

"Terrified doesn't begin to describe how I felt." He confessed, his hands shaking just a bit as he did. He wrapped them tighter around the glass to stop the tremors as he continued. "I slept in the nursery the first couple of weeks, waking up every hour or so to make sure they were still there."

"And Tatia?" Caroline asked hesitantly.

"She left a note in their diaper bag. She said she couldn't handle being a mother or wife anymore and she was leaving me with the family I had wanted more than her."

"Katherine said you never looked for her?"

"No. I filed divorce and custody papers the next day, citing abandonment. It was granted six months later," Klaus answered before he sat back down. "I never looked for her because it was her choice to leave. If she didn't want to be around the twins, I wasn't going to force her to be. They have too many people around them that want to love them, why subject them to someone who doesn't? I know what that's like, and I won't do that to my children."

Caroline wanted to ask him what he meant by his last statement but let it go. He had confessed so much to her that she didn't want to press more.

"I don't know what to say." She felt like she should say something, but she had so many things running through her it was hard to wrap her head around any of them. She felt like reaching over and offering some comfort to him while at the same time the desire to call her mother and use her law enforcement connection to track down Tatia and wring her neck. She hated a woman she had never met.

"There's nothing to say. It's in the past," he said, a large sigh coming from his lips.

The two of them lapsed into silence after that, neither one of them felt the need to talk after so many words had already been spoken.

Okay guys there it is, Klaus and Tatia's history, well a lot of it;). I know it was a little short but had a lot in it. What did you think?

Sorry if I went a little soap operay with the whole mistaking the twin of your wife for your wife and sleeping with her. Or almost. But I wanted to include the Elijah/Klaus/Tatia triangle from the show, even if we haven't learned much about it, so I came up with this.

And I'm not sure how this keeps happening but I keep mentioning things from Spielberg movies, first there was a line in part 5 from Jurassic Park and in this one I mention Amity Island which was from the Jaws Movies. Not sure why I keep doing that but there it is.

The next part will be more light hearted, and move forward in time to Christmas. Christmas will only be one part before they head out on vacation.
