I've learnt some things are better kept secret.

"Shouldn't we wait for back-up to arrive?" Caroline asked as her and Klaus climbed out of his Jeep. Ric had texted them the address of Marcel's location which had led them to a building at the docks.

Klaus looked over at her, "If we wait Marcel could be gone before we get to him. Our best chance is to go in now."

Caroline nodded knowing he was right, she checked the gun tucked into the waistband of her jeans subconsciously, "Well out of all the things I imagined for the morning after our first time together," She sighed gently, "This definitely wasn't one of them."

Klaus quirked an eyebrow at her, "You thought about us sleeping together?" he smirked.

Caroline blushed, "Like you haven't."

"Of course I have, love. In fact I would go so far as to say thinking about it made all those board meetings a lot more enjoyable." He grinned.

Caroline was shocked that he fantasized about them hooking up when he was meant to be focusing on their regular debriefing.

"Nik, wait." She said gently. Klaus stopped and turned towards her. "Marcel is clever and angry, that's a bad mix. So whatever happens in there…"

Klaus cut her off by placing his lips on hers, "Nothing is going to happen in there, Caroline." He whispered as they broke apart, "I won't let anyone hurt you."

"It's not me I'm worried about." She confessed quietly although she knew Klaus heard her.

"You're remarkable, you know that? We are about to walk into danger and you're worrying about me?" Klaus chuckled softly, "We are both going to be fine sweetheart, and then I am taking you on a date. Wherever you want to go." He said lovingly as he grabbed her hand and held it to his chest, "Whatever you want, I'll give it to you."

Caroline smiled and brought her other hand up to his cheek, "I want you." She whispered into his blue eyes, "Only you."

Klaus kissed her forehead softly, "You have me." He pulled back from her and grabbed his gun, "Hell, I think you've had me since the first moment we met." He laughed.

Caroline gave him another glance but she replied, "Let's go catch a bad guy." She pulled out her gun too as they made their way closer to the building.

As they got closer Caroline couldn't help but think about how she should be scared, how anyone else in her situation would be. Marcel was unstable and out for blood, there was no telling how this thing would play out, even with their CIA training. But Caroline wasn't scared. She knew Nik would have her back if anything happened like she would have his. It was how they always worked together.

Caroline's breath caught in her throat as she heard Klaus roar in pain. She sped up her pace and rounded the corner to find her partner on the ground with a wooden beam sticking out of his back. She grimaced in sympathy.

"What the hell happened?" She asked as she tried to help him up.

Klaus grunted in pain, "They ran out of bullets and decided to get creative." He winced as he was hauled up, the movement jostling the wood lodged into his back. Caroline placed an arm round his waist and threw his over her shoulder as she led him out of the room.

"You probably shouldn't have blown up their car. I told you it would piss them off." Caroline sighed as they entered the next room in the house they were currently trapped in. People surrounded them on all sides so they would have to fight their way out, not that Klaus could do any fighting in his condition.

Klaus winced as Caroline let go of him, his shoulder blade moving causing the wood too as well, "Caroline," he said roughly, pain evident in his voice, "You're beautiful but if you don't shut up I will kill you."

Caroline glared at him, wondering for the millionth time why the hell she was paired with an arrogant ass like Klaus Mikaelson. "Then you would be stuck in here without any back-up. Great plan." She said sarcastically as she checked the windows for any signs of movement.

"You have to remove the wood from my shoulder." Klaus said as he found a pair of pliers on the abandoned table.

Caroline stared at him in shock, "No way, I'm not a medic besides it will hurt like hell."

"Love it already hurts like hell besides I can't shoot a gun without moving my shoulder. I can't risk the wood getting deeper into my body." Klaus explained. Sweat was beading on his forehead and Caroline didn't want to think about how much pain he was in.

"I can't." She said softly.

"You can." Klaus nodded, "I know you can do this, Caroline." He said as he handed her the pliers.

"What are these for?" She asked, the wood was visible she could simply pull in out.

"The splinters."

Caroline felt a little sick at that point but she took a deep breath, "You owe me." She muttered as she guided him into a chair. She stood behind him, bracing on hand on his good shoulder, the other wrapped around the wood.

"Just do it quickly." He said when he felt her hesitate. Caroline nodded and in one swift move pulled the wood straight out. Klaus screamed in agony as the wood was removed and clattered to the floor.

"Sorry, sorry!" Caroline replied frantically.

"It's okay, its good. Thank you." He said softly and Caroline was shocked. That was the first time she had ever heard those words him. .

"Yeah, you're welcome." She said taken back.

Klaus approached the door to the building while Caroline texted Ric about back-up. He nodded to her once; a signal. Caroline nodded back and clicked the safety off her gun. Klaus waited for a second before entering the building with Caroline behind him.

The building was one big room and it looked as though someone had been living in it. There was a small camp bed on the far wall and a network of computers set up in the centre of the room. Pictures and notes cluttered the walls that were rusted and peeling. Caroline guessed this was where Marcel had been running his business from. She couldn't imagine Tyler here; he hated things that he deemed beneath him.

"Klaus Mikaelson." A voice said from behind them as the door slammed shut, "I was wondering when you were going to pay me a visit."

The man stepped forward as both Klaus and Caroline raised their guns on him. He was a tall man with brown eyes, a shaved head and dark skin. Caroline knew from the photos she was standing in front of Marcel. He looked chilling and somewhat regal. She wondered briefly if Klaus had mastered that look too.

"Marcel." Klaus responded curtly.

"It's been a long time, man." Marcel said with a smile, "But please put the guns down, yeah? Is this anyway to treat an old friend?"

Klaus and Caroline didn't move. "It's the way we treat a murderer." Caroline said harshly.

Marcel laughed, "And who's the girl? Don't get me wrong she is stunning. The CIA didn't have woman like her when I was around."

Klaus practically growled, "Stay away from her."

Marcel raised his hands in a surrender motion, "Don't worry I know you hate to share."

"You also know I don't follow orders." Klaus replied, "So I suggest you make this easier for yourself and get on the ground."

"No can do." Marcel said as he walked closer to Caroline. The blonde held her ground, "But I'll make you a deal? You two drop those guns and kick them over to me and I won't kill you."

"We don't negotiate with criminals." Caroline spat out.

Marcel laughed again, "She's feisty. I see why you like her. Come on now Klaus, you know how to play the game. You do as I say and I give you the information you are looking for."

Klaus sighed, "Caroline, drop the gun and kick it over to him."

Caroline looked at him as if he was mad. Klaus' eyes were pleading with her to trust him. Caroline did as he said and kicked the gun to Marcel. Klaus followed suit and did the same thing.

"What happened to you?" Klaus asked him as he inched closer to Caroline.

"You did." Marcel stated as he grabbed their guns. He pocketed one but kept the other in his hands, "You are responsible for the man I became. You made me."

"I never made you this." Klaus replied

Marcel laughed, "Of course you did." He stepped closer to Klaus, anger burning in his eyes, "You took everything from me, Klaus."

"What are you talking about?" Caroline demanded, she was completely lost.

"Okay, history lesson." Marcel rubbed his hands together, "When I was training in the CIA program with Klaus he became a mentor to me. I had no family and Klaus was there for me. He was the only person in the world I trusted." Caroline looked at Klaus then but his eyes were focused on Marcel, "I had a girl back then. She was beautiful and I loved her. She was pure and good in a world that was frankly a damn mess. She wasn't perfect though, she made mistakes, got involved in the wrong things."

"What does that have to do with Klaus?" Caroline asked.

"Klaus and I were assigned to different teams after we completed our training. His first mission was to investigate a deal shipment but something went wrong. You remember that mission right?" Marcel asked looking at Klaus.

Klaus nodded, "Our job was to stop the shipment from being sold on from the suppliers. We raided this house where the drugs were being stored; it was full of dealers and users. The dealers had guns and opened fire on my unit so naturally we returned fire. Two of my men were killed in the shoot out along with 5 people in the house. Some were dealers, some were drug users."

"One of those drug users was my girl. She was in the wrong place at the wrong time with the wrong crowd. Klaus killed her." Marcel said bitterly, "Klaus Mikaelson killed the woman I love. When I found out I was hurt, angry. I wanted you to suffer. I couldn't think of anything that deserved my loyalty anymore. I killed my unit to punish the CIA for ordering the hit in the first place."

"I didn't know you're girl was in there. I never met her; I followed my orders and protected my guys." Klaus said as he took a step closer to Marcel, emotion evident in his voice.

"It doesn't matter. You still killed her! This whole thing wasn't about power; it was about causing you and anyone you care about pain." Marcel said as he raised the gun to Klaus, "But you know what? Killing you works too."

Caroline saw Marcel squeeze the trigger. Before she could even comprehend what was happening she charged at Klaus knocking them both to the ground. They hit the concrete floor hard and Caroline felt pain explode through her side. Klaus sat up and looked at her, worry in his eyes.

"Caroline," He said softly as his eyes travelled down to her stomach. Caroline's eyes followed his and she gasped. Blood was spreading out of her stomach, soaking her shirt. Klaus gently pulled the shirt up and they both saw the bullet wound. White pain spread throughout her body, black spots appearing in her vision. Klaus pulled her into his arms where she collapsed against him, tears stinging her eyes. She groaned as Klaus pressed his hand against her wound to try and stem the bleeding.

"She must really care about you to take a bullet for you. I did you a favour really," Marcel said as he crouched down beside them, "You would only end up hurting her, at least now you wont be able to disappoint her."

Klaus glared at him, "I'll kill you, Marcel. I will hunt you down and kill you." The only thing stopping him now was the blonde woman in his arms who was clutching his bicep to try and block out the pain.

Marcel laughed, "I look forward to it."

The door burst open as their back up arrived. Marcel's eyes widened and he tried to make a run for it. Klaus grabbed the gun Marcel once held and fired a shot in his leg. Marcel fell to the ground in pain.

"That's for Caroline." Klaus muttered darkly.

The units moved in on Marcel and cuffed him and Klaus couldn't help the feeling of smugness that overcame him. He wouldn't kill Marcel; letting him rot in a tiny cell for years while Klaus personally took down his inner circle would be a much sweeter torture.

"Caroline stay with me, love." Klaus said softly as he smoothed her hair.

"I'm tired, Nik." She whispered and Klaus kissed her forehead.

"Stay awake for me, sweetheart. Fight for me. I'm going to get you to a hospital. You are going to be okay, Caroline. You have to be okay."
