The inspiration for this AU came from amykinz13's story, "Anger Managment." I was originally going to do it as a stand-alone one shot, but I changed my mind and decided to include it as part of my one-shot series.

Thank you for the great reviews so far!

Forbes House – Midnight...

Thunder roared and lightning flashed outside her window as Caroline tossed and turned in her sleep. She was having a very intense dream, mostly because the storm itself was intense. After a few more tosses and turns, the blonde vampire forced herself to wake up and then went to the bathroom to wash her face. Why the hell did she suddenly have that dream? She thought that she stopped having it a long time ago, but apparently, it resurfaced.

After drying her face, Caroline returned to her room and her senses alerted her to another presence. Turning on the light, she gasped when she saw Klaus standing by her bed, wet from being out in the rain. If Caroline wasn't so confused by the strange resurfacing of a past nightmare, she probably would've found that somewhat attractive.

"Klaus, what the hell are you doing here?" She looked at the clock. "Seriously, it's after midnight. Shouldn't you be home and in your own bed?"

"I couldn't sleep, so I thought I'd take a walk," he replied. "Anyway, I sensed something coming from your house and came here to investigate it. When I came in, I found you gone, but sensed that you were in the bathroom, so I decided to wait until you came back."

"Uh huh, you were just in the neighborhood?"

Klaus ignored her and said, "Is everything all right, Caroline?"

"I'm fine."

"The energy I detected from you tells me otherwise," said Klaus. "Something happened and I need to know what it is so that I can help."

Caroline sighed. Why was she not surprised? Klaus seemed to enjoy rescuing her. Deciding that it would be pointless to lie, she sighed and sat at her vanity. "I had this dream tonight, a dream that I thought I stopped having a long time ago. I don't know why, but it's resurfaced and it scared the shit out of me."

"It must've been some dream if it got you so disturbed," said Klaus. "What happened, do you remember?"

"It was more of a bad memory," said Caroline. "I was still human and Damon was using me as his personal blood bag."

"He what?" Klaus clenched his fists at that.

"He fed on me, abused me, pushed me around and even took my memories away."

"I can't let this matter go unpunished," said Klaus. "Damon needs to be taught a lesson about how to treat a lady. He had no right doing what he did to you."

Caroline sensed how angry Klaus was getting. "Klaus, don't, okay? You don't have to avenge me. I already avenged myself after I was turned and all of the memories came back in flashes. I tracked Damon down and kicked his ass for what he did to me. We're sort of friends now, even though I see him as an annoying brother despite being my sire."

"You're sired to that arrogant piece of trash?"

"Well, yeah, as much as I don't like it," said Caroline. "I had his blood in my system when Katherine smothered me with that pillow in the hospital. So, technically, I'm sired to Damon. But, I don't always do what he tells me, mostly because I think he should a long walk off a short pier."

"You still didn't deserve to be treated that way," said Klaus. "As I said before, I can't let this go unpunished. Damon will pay for this."

He went to leave, but Caroline quickly grabbed his arm, not giving a shit if he was stronger. "No, Klaus, don't hurt him. If you have any honor at all, you'd spare him. He's learned his lesson...at my hands, even if he did try to kill me after I avenged myself."

After she said that, she placed her hand on her mouth, but she wasn't fast enough. Klaus already heard her and he wanted to punish Damon even more. Bad enough he tortured Caroline for her blood, but to try to kill her after she was turned? That was even worse.

"Caroline, I need to do this. You may think that I don't, but I can't accept that."

Caroline was about to protest when he gently grabbed her arms and pulled her to him, kissing her gently and passionately. After a moment of hesitation, Caroline returned his kiss. She still thought he was nuts to try and avenge her like this, but he had insisted on it. Finally, Klaus stepped back, reluctantly breaking the kiss. It was obvious that he wasn't going to listen to her, so what was the point in arguing with him?

"All right, fine, you can avenge me," she said. "Just promise me that you won't kill him."

"I can't promise that, love."

"Okay, what can you promise then?"

"That I'll teach Damon a lesson in respect that he won't soon forget," said Klaus. "I don't care how it gets done, but it will get done." He saw the look in her eyes and rolled his own. "All right, I'll try to show restraint...for you."

Caroline was about to speak, but Klaus was gone before she could get the words out. She knew that he wasn't going to be able to control himself, considering how Damon had a big mouth. Thinking quickly, she threw on some clothes and vamp sped out of the house. She probably wouldn't be able to do much, but at least she could try.

Salvatore Boarding House – Later...

Damon was just about to head upstairs when he heard a knock at the door. Funny, he wasn't expecting anyone, so who the hell would be coming by at this hour? His curiosity piquing, he opened the door and saw Klaus standing there, drenched and pissed.

"What the hell do you want?"

"Retribution."

"Oh, yeah, I remember seeing that movie," said Damon. "It sucked."

"You know damn well what I meant by that," said Klaus. "I want retribution...for Caroline."

Damon scowled. "Since when do you care about that? As I recall, Caroline didn't complain about the way I treated her...not much, anyway."

Klaus flew into a rage and forced his way in, picking Damon up rather roughly by the neck, his fangs extending as he looked up at him. "She didn't deserve to be treated that way! I don't care what your reason was, you still shouldn't have done what you did!"

That being said, he threw Damon across the room, making him land rather ungracefully by the fire place, grabbing him and, twisting arm behind his back, forced his other hand into the flames. The noise unfortunately woke Stefan, who appeared behind the hybrid.

"Klaus, what are you doing?"

"What does it look like he's doing?" said Damon, his voice a bit strained. "He said he's getting retribution for Caroline."

As though he knew what the other Salvatore was going to say, Klaus said, "Yes, Stefan, your brother needs to learn a lesson in treating a lady with respect. What he did to Caroline was unforgivable, especially as far as I'm concerned."

Stefan was about to say something when Caroline herself arrived at the boarding house and saw what was going on, gasping and going over to Klaus before Stefan could stop her.

"Klaus, stop it, you proved your point!"

Damon looked at the blonde. "Get out of here, Blondie, he's nuts!"

"No, Damon, as much as I hate you for what you did to me, killing you would've been too easy." She looked at Klaus again. "Klaus, please, if you care about me, you'd let him go. He's learned his lesson."

Klaus reluctantly released Damon from his grip and Stefan helped his brother up, leading him away so that the pair could talk. Klaus watched as the Salvatores walked away, growling in frustration before looking at Caroline again.

Before he could say anything, she said, "You know, I had a feeling that you'd avenge me anyway after I told you that you didn't have to. Why must you always prove how much pain you can inflict on someone? I know you love me, Klaus, but seriously, I can fight my own battles."

"That was why I did what I did."

Caroline shook her head. "I can understand that, and while you didn't have to defend my honor, I know that you wouldn't have been satisfied until you saw Damon begging for mercy at your feet." She went over and hugged him. "Thank you."

Klaus forced a smile and returned her hug, running his fingers through her damp hair as they stood in front of the fire place.

Note: As I said in my first note, this was originally going to be a stand-alone one shot, but I couldn't resist adding it to the series I'm already working on.
