Klaus arrived in Caroline's house after he had gone to the wake and heard that Caroline hadn't attended it. So he sped to her house to check up on her, feeling that something was very wrong
After knocking and having no answer, he opened the front door and stepped into the house.
"Caroline?"
No answer, as he walked further into the house, he saw that Elena was lying in a hallway and was currently waking up.
"Elena, what happened?" He asked her, standing over her as she also stood up to level with him.
"You happened, Klaus." She said as she started walk out the door, when Klaus grabbed her arm.
"What are you talking about, doppelganger?"
Elena tried to pull away, but his hold was firm.
"She flipped the humanity switch, Klaus. She would never snap my neck otherwise. And that's on you, Klaus."
Klaus was shocked to hear that, "S-She did what?"
"Turned off her humanity, Klaus. Because her mother died and then she heard your plans for using her to get to us. It was a low blow, Klaus. How could you do that to her?"
Klaus didn't understand the word she had said at first and then it dawned on him.
"Oh my god." He said as he released Elena and flashed away.
"Hello, my glass is empty," Caroline yelled to get the bartender's attention.
The bartender came and started to fill it when Caroline grabbed the whole bottle of whiskey..
"Hey, If you want to buy the whole bottle, let me know first okay."
"I don't want to buy anything, I just took it, cause I want it and I don't have to answer to anyone."
"Okay, I'm cutting you off and calling you a taxi."
The bartender tried to take the bottle from her but she leaned closer to him and looking straight in his eyes, he said, "You are going to let me have the booze for free and you are going to pay it with your salary for being so rude."
"Yes, sure, have the bottle, it's on me."
"Thank you…" She looked at his name tag and said, "Jason."
"Caroline Forbes, in Rabbit Hole's, What made you come in this part of town?"
Caroline turned to see a guy she didn't recognize smiling and checking her out.
"What do you want?" Caroline asked impatiently.
"I just saw you here alone and thought you could use some company."
"Who are you again?"
"Ah, sorry, I attend Witmore with you and we have Mr Saltzman together."
"Is that so," Caroline leaned closer to him and whispered in his ear, "I could really use some good company tonight. Meet me outside in 5."
"Sure," The boy grinned, like he had won the lottery or something.
"Good, see you there."
Then Caroline went to the bathroom and checked the boy's phone that he had stolen from him.
1 unread message from Elena Gilbert. It had her picture and "Let me know if you see her. Don't approach. Dangerous."
Caroline laughed at that. They were already searching for her and using all their contacts.
Then she looked at his older messages and noticed one from Hayley Marshall,
"Had a good time the other night and PS! And beware of Caroline Forbes and her friends in Witmore, they are bad news."
At first she was totally indifferent to that but then felt something deep inside. It was a shimmer of an emotion – hate.
But she collected herself quickly and went outside to meet the boy.
"So you have bedded Hayley Marshall," She said approaching him, as he was smoking in the alley behind the bar.
The boy looked like a deer caught in headlights.
"I-I have, yes, but it was a short relationship."
"I see. So why did you approach me today, if she warned you against it?"
"Come one, it's just a little cat fight you have going on. I wasn't worried. Now can I have my phone back, please?"
"You sure can." Caroline approached the boy and slid the phone to the front pocket of his jeans, all the way down, brushing gently past his manhood as she did it, causing the boy to freeze in place, turned on by that gesture.
"So what's your name?" Caroline asked staying close to him, only a couple inches away.
"Lucas." He answered while Caroline hands travelled up and down his chest.
"Okay, Lucas, whatever happens you don't move a muscle, including your mouth," she compelled him to stand still.
Then she revealed her fangs and veins around her eyes darkened as she bit his neck and drank. It was so good to drink fresh blood, it was intoxicating. Soon she felt his pulse slow down but she didn't care. She wanted the blood so bad.
Suddenly she felt herself thrown to the opposite wall and when she stood up, she saw that in front of Lucas stood Stefan Salvatore and further away was Klaus Mikaelson himself. Stefan seemed angry and worried, Klaus had guilt written all over his face.
"Hey, what's up guys, What brings you to this part of town?" Caroline asked as she fixed her dress and hair.
"Caroline, we are here to stop this nonsense and Klaus has something to say."
Caroline laughed, "Okay, so let's hear it."
Klaus walked to her and took her hands in his. While she tried to break free, he was stronger.
"Caroline I am so sorry about what you heard today, but it was all a silly joke. I didn't want to reveal my feelings for you to my brother, so I made a stupid joke about using you to get revenge on your friends. I'm really sorry, Sweetheart. Please stop this, it's not you. And come back to me."
Caroline looked at him seriously for a moment and looking past him, he asked Stefan, "Are you buying this?"
"Because I sure don't," Caroline said, as she used Klaus' distraught state to kick him in between his legs and use all her strength to send her flying.
Stefan was too shocked to follow Caroline as she flashed away.
"So, all you want is for us to leave you alone, and then you promise not to kill anyone?" Elena asked Caroline with confusion when they had met in their shared dorm room and Bonnie was also included as she was back from the prison world.
"That's all I want. Now granted, if anyone tries anything to flip my switch back on—- and I mean anything, I'll become your worst nightmare."
Elena and Bonnie exchange anxious glances.
"Great! I'm gonna get a latte." She said smiling while leaving the room.
Elena, Bonnie, Klaus and Stefan had all gathered in their Dorm room to discuss the situation.
"Klaus, Can't you just compelled her to turn it on?" Elena asked
"Firstly, I can only compel to turn it off, secondly, even if I could, I would never do it, because I have never had to compel her before and I am not starting now either."
"Great, you did this and Now you are not even going to help," Bonnie muttered.
"I didn't say that. Look, she said no interrupting her, but her anger is directed at me, for a good reason, and what can she do to me."
"She doesn't feel anything right now, that is the problem, Klaus." Stefan said impatiently
"You're wrong, this state she's in, she's great at control but right now her trigger is hate, toward me, towards Hayley and life itself. We can use it against her, I'm gonna be her punching bag, she won't even remember to hurt anyone else. I'll interrupt her, and I'm gonna pay the price. Only me."
Stefan, Bonnie and Elena shared anxious looks.
"Look, this is between me and her. I'm gonna push until she is gonna crack and she will."
"Okay, we will play by her rules while you do what you do." Stefan said and then looking at his phone, he continued, "Enzo contacted Damon, that she's on her way to a college rave."
"You all stay away, I'll go in." Klaus instructed them.
Klaus found her at the bar doing shots with some meat head. Her hair and close were different, but she was Caroline and he knew how to push her buttons.
So first thing he did approaching her, was to compel the meat head,
"Leave. Now."
"Hey, what do you think you are doing, Klaus?"
"I'm just here to drink with you and I don't want any competition."
"Okay, If you plan to use me for some plan, go ahead I don't care about their fate."
"You know, Caroline, I have waited forever to hear you say those words."
"That's all you do, Klaus, wait on me."
"Maybe. But you like it."
"Maybe I did, but now I'm frankly over you. So I'm gonna go back to Aleksei, you know he's from some East-Europe country, I think it was Slovenia or something. So very exotic compared to you."
Klaus grabbed her arm and his demeanour had changed to serious, "Go have fun, But I won't let you become your own worst enemy. So I will be watching over you. And ruin your "fun" if it gets out of hand."
"You don't want to do this, Klaus. I like I said to the dim-witted Elena and Bonnie, I will become your worst nightmare, If you don't let me go." She threatened him.
"Is that anger you are feeling, sweetheart. Very good, let it in. Be angry, hate me and everything and everyone. Believe me it's good for the soul."
Caroline inched closer to him and grabbing his face, she kissed him passionately, during which she snapped his neck and then she started what Klaus was firmly against – Caroline becoming her worst enemy.
So while he was unconscious, she started killing randomly everyone she could get her hands on. Although scared people rand for the exits, Caroline was faster, ripping people apart left and right.
When Klaus woke up, he woke to warehouse where dozens and dozens of bodies were lying around.
"Good job, Niklaus. As always."
It was Elijah, accompanied by Stefan Salvatore.
Stefan just shook his head looking at the massacre.
"So I made some miscalculations. Seems I gave her the Idea how to get to me. By destroying herself."
Stefan closed his eyes for a moment and sighed.
"What now? Are we going to see where the blood trail is going to lead?"
"Sure, but it's not gonna be pretty. If she's off to destroying herself…well the possibilities are endless." Klaus said and kicked a few glasses and bottles off the counter in anger.
So they walked outside and the bodies and blood led them to an alley. At the alley they found her torturing a girl who couldn't be more than 15 years old.
She stabbed the girl in various places, let her scream in agony and then healed her and started again.
"Caroline, stop it." Stefan yelled.
"What, I'm only starting now." She said as she victoriously smiled when the girl healed again.
Klaus flashed to where she was and threw her as far as he could. Gave the girl to Stefan, who flashed away.
"Oh, come on, Klaus, you have done far worse." Caroline said standing up and walking away from them.
Klaus flashed to her and grabbing her from behind, he stabbed her with a syringe and vervained her.
"I'm sorry sweetheart, but you are giving me no other choice." He said as her body fell limping down and he caught her in his arms.
