Caroline twisted Katherine's arm, grabbed the back of her neck with her free hand and pinned Petrova against the wall.

"What are you doing here, Katherine?" Caroline hissed through gritted teeth.

"You've become stronger. Impressive." Katherine gasped. "Still not strong enough to take me down." Brunette used the back of her head to hit Caroline's face. Blonde loosened her grip, she began bleeding out of her nose and lost her balance.

"You broke my nose!" Caroline screamed angrily. Katherine sped to her and threw her across the room. Blonde quickly stood up and was ready to attack Katherine again when she spoke.

"Calm down, Caroline. We both know that I can easily kill you." Katherine neatened her hair. "I didn't come here to fight."

"So why are you here?" Caroline asked resentfully.

"Because of the Originals." Katherine walked up to the couch and sat down.

Caroline was staring at her, she didn't understand anything. Katherine rolled her eyes.

"Weren't you at least suspicious why Klaus decided to visit you completely out of the blue?" Petrova said confidently.

"How do you .." Caroline was surprised that Katherine knew that Klaus was supposed to come to Mystic Falls.

"I know more than you can imagine." Katherine said smiling. "Even about you.." She added meaning that she knew about Caroline turning off her humanity.

"Oh yeah." Caroline huffed being tired of Katherine's behavior. "What do you know about me that I don't know?" She asked actually being a bit curious.

"I believe that your hybrid-boyfriend will tell you everything." Katherine answered pulling a face to show her disgust.

"Tyler is not my boyfriend anymore." Caroline countered crossing her arms over her chest.

"I'm not talking about this jerk." Katherine responded looking at her nails. "I meant an ORIGINAL hybrid." She added giggling.

Caroline blushed, she had to turn around so that Katherine couldn't see it. "He's not my boyfriend." She claimed cleaning the mess that her and Katherine had done.

"Never mind." Katherine obviously didn't want to know any details. "You're so impolite, Caroline. You didn't offer me anything to drink." She pretended to be aggrieved.

"Seriously Katherine. Stop your stupid games. Tell me why are you here or get out." Caroline demanded giving Katherine a fierce glare.

"Chiiiiill. You big baby. I'm here because your parents-in-law" Katherine couldn't resist a smile here. " are plotting against Mikaelsons. Basically it's the same old story. Mikaelsons are fighting each other." Brunette claimed and took a deep breath.

"What does it have to do with you and me?" In fact, Caroline had no idea why Katherine was here, and what she was talking about. "And who the heck are my parents-in-law? Stop it, like seriously." Caroline was annoyed with this whole situation.

"And I thought that you are smarter." Petrova gasped and stood up. She began looking at Caroline's photograph on the mantelpiece. "You were so sweet. I'm sorry for your loss." She added pointing a picture of Liz.

Much to her surprise, Caroline didn't feel pain when Katherine had mentioned her mother. She thought that maybe it was caused by the fact that she was grieving Liz for such a long time that she was finally over it. "Thank you." Caroline replied avoiding Katherine's gaze.

"So… How did you manage to deal with your mother's death? I heard that you two were pretty close lately." Katherine inquired, but obviously she knew how Caroline dealt with it.

"I…" Caroline started, but her mind was kind of empty. Katherine looked at her smiling devilishly.

"You what?" Petrova asked in a fake curious voice tone.

"Seriously Katherine. You don't even care so why do you want to know how I dealt with my mum's death?" Impatience was growing inside Caroline with each Katherine's statement.

"We're becoming friends, aren't we?" Katherine forced a fake smile. "I just want to get to know my bestie."

"I'm not your friend. I loathe you." Caroline snarled.

"Ouch. Why are you so harsh?" Katherine began pacing back and forth in front of the window. "Do you remember EXACLTY everything since your mother's funeral?" Petrova emphasized on purpose.

"Of course I do." Caroline shot back, but suddenly she felt a wave of cold inside of her body. "I don't."

"And here we are!" Katherine clapped her hands in triumph. "What do you remember?"

Caroline was thinking how it was even possible that she couldn't remember what she had been doing over the past couple of days. "I was crying, Elena and Bonnie were visiting me every day, so was Stefan." Blonde began to count out the activities.

"Anything more?" Katherine teased trying to make Caroline understand that she was compelled.

"No." Caroline replied still trying to figure out what could have happened.

"You seem to be confused." Katherine claimed pretending to be worried.

"Because I am. I only remember that I was crying, but I don't remember anything else, even what I was wearing." Caroline acknowledged.

"Come on Caroline, there must be something in that pretty head. What can we do to people to make them feel exactly the same?" Katherine hinted.

Caroline's eyes widened as she understood what happened. "I was compelled."

"Wow, you're genius…" Brunette rolled her eyes.

"Why?" Caroline was pretty sure that Katherine knew everything. "Tell me." She demanded an answer.

"My part is done now. I can't be here when Klaus shows up." Petrova stood up and flashed out of Caroline's house.

"Wait!" Caroline screamed, but she was already gone.

Katherine was far away enough to stop, she pulled her phone out of her purse and dialed last used number. After few seconds she heard a voice.

"Hello Katherine." A woman was talking at the other end.

"I did what you wanted. Now, let him go." Katherine said trying to sound serious, but in fact she was shaking inside, worried that they could have hurt him.

"Well done. He'll be free by the sunrise."

"You said that he'll be free if I do what you want. I did, so let him go now." Katherine demanded.

"Calm down, child. Our collaboration is over."

Katherine wanted to say something more, but she heard a beep. She crushed her phone in anger. "If that wicked bitch dared to lay a finger on him, I'll rip her hear out and feed her with it." Petrova thought full of rage.

Caroline finished cleaning broken pieces of furniture and began to prepare her for sleep. She put her nightie on and lay down on the bed. Thoughts were racing in her mind, she couldn't fall asleep. Katherine said that Klaus would tell her everything. Did it mean that he compelled her? Why would he do so? Now, she wanted to see him even more. Caroline closed her eyes and tried to soothe her mind. After what seemed to her like millions of positions Caroline finally fell asleep.

Caroline looked around, she was standing in the forest. Somehow it seemed to be familiar, but she couldn't remember when she was there. Suddenly, Caroline felt an urgent feeling to run, her legs moved faster and faster, but she was aware that she couldn't escape. He flashed in front of her, Caroline looked into his deep blue eyes so beautiful yet murderous. So frightened was she that she wasn't able to run away. "Please!" She cried out as he sank his teeth in her neck.

Caroline woke up screaming, she sat in her bed immediately. "God…" She gasped placing hand on forehead. "It was only a nightmare." She mumbled to herself. Caroline rubbed her neck and felt something wet on it. She looked at her hand, her eyes widened, there was blood. Blonde's heart started racing, she sped to the mirror on the wall. Nervously she checked her neck looking for a bite, but nothing was there. Caroline frowned as she didn't understand what was actually happening.

"I must have scratched my neck while I was having this nightmare." She assured herself, but look in the mirror one more time to be sure that she was completely safe.

Caroline started preparing herself for Klaus' visit. She had been so happy about this, but now she felt anxious. It was caused by Katherine and this creepy nightmare she had this night. Caroline put her favorite dress on and curled her hair. She checked herself in the mirror and went downstairs to eat something. She opened the fridge and started looking for her favorite blood bag. Caroline straightened up, closed the fridge door and screamed in fear.

"Hello, Caroline." Klaus said grinning at her as usual. "I didn't mean to scary you, but I must admit that it was pretty amusing."

"Klaus…" Caroline was both excited and nervous seeing him. "I was about to fill my energy." She showed the blood bag. "Need some?" She asked politely.

"I'm fine, love." He replied smirking.

Caroline felt extremely awkward, she didn't know where to start, she wanted to ask so many questions, but she decided that it was inappropriate to began their conversation interrogating him.

"So…" Caroline started after she had finished drinking blood. "How are you?"

"Seriously Caroline? How are you? You are so dumb." She thought. "I could have come up with something more creative."

"Well I'm great." Klaus lied to her, but he didn't want to overwhelm her with everything happening right now. "And you?" He was even avoiding looking into her eyes.

"I'm fine, thank you." Caroline replied forcing a fake smile.

Klaus started looking at her cautiously. She felt like he was analyzing each word she said, and she didn't say anything complicated, just answered his question.

"What's going on, love?" Klaus asked looking into her eyes. "I know you're lying."

Caroline bit her lower lip, she didn't know where to start. Should she ask about what Katherine said or maybe mention her nightmares? "I had a dream, actually more than one, about you.." She began speaking hesitantly.

Klaus chuckled. "Isn't it something unusual, love? Look at me." He smirked.

Caroline rolled her eyes and gave him a smack. "It's not funny. In my last dream you bit me." She declared and saw that his facial expression had changed. Now, he was serious, and apparently he was thinking about something. "What's more.." She didn't know if she should mention that she woke up with blood on her neck.

"Tell me, Caroline." Klaus demanded frowning.

"I don't know if it's even caused by this dream…" Caroline hesitated but decided to tell him. "I woke up with blood on my neck."

She jumped as Klaus flashed to her checking her neck. Caroline could swear that he released a breath of relief. Caroline looked at him obviously signalizing that she was waiting for an explanation of his behavior. "You're not telling me something." She whispered as they were so close at this moment that she didn't have to say it out loud.

Klaus turned around and started pacing the kitchen. He wanted to spend some time with her first, and now he had to tell her the truth which was actually brutal.

"The truth is that I came here to look after you." Klaus thought that maybe it would be enough for her.

"Why?" She demanded crossing her arms over her chest. "Seriously Klaus. I want to know."

"Can't you be just happy with what I have told you love?"

"No." Caroline shot back, at least he tried.

Klaus tried to find appropriate words to say it, but everything seemed to be bad. "My mother needs you." He finally spoke.

"She's dead, Klaus. Why would a dead witch need me?" Caroline thought that he was lying.

"Apparently she's not. She used some sort of an ancient magic to bring herself back from the other side taking her husband with her along the way." Klaus said irritated about the fact that his mother brought Mikael back to life.

"Wait. You mean Mikael?" Caroline asked a bit shocked by this piece of news.

Klaus only nodded in agreement. "And they want to make my siblings and me mortal again."

Caroline opened her mouth in disbelief. "Is that even possible?"

Klaus looked at her his gaze full of pain. "She can do it by casting a very strong spell. To cast this spell Esther has to sacrifice the ones we love."
