Hey guys :) So here is my fanfic. It is just a little one-shot writen of boredom. I hope you like it. It is set during S3 and lets just ignore Josh okay? :D So I hope you enjoy it.

Disclaimer: I do not own anything from Castle, but who know? Maybe Stana and Nathan are hiding under my bed right now...

Cold. Warm. Cold, again. Both at the same time? How was that even possible? Kate Beckett was sitting at her desk, filling the the last pages of paperwork from her recent case. They finally got their guy, after three days of practically chasing their own tails and reading through tons of case files connected to their suspect. How could one person have so many connections was beyond her. She didnt think it was even possible. Until today.

After hours of going through houndreds of statements, they found one witness hidden in some warehouse. Castle really helped with finding a clue through his theories. They were actually good if you left out the CIA and allien abduction parts. Not that she would ever tell him that. His ego was big enough already.

Even after getting the witness to the precinct, it took them almost three hours to crack him because he was so afraid of his employer. She was glad that it was finally over, because she was completely exhausted and she felt really strange. She was having some kind of a flu the last couple of days, but today it was just getting worse. She could feel the headache already forming and totally did not feel her nose. I will just finish the paperwork and hopefully there will be no boy drops so I can go home.

Her big, warm and comfy bed was looking like a piece of heaven after today. With that vision in her mind, she continued her writing. Just three more pages, she told herself. As she was writing the last page, Kate sneezed so badly she thought her head was going to fly away. If she would expected it, it will be OK but this just came out of nowhere. She quickly looked for some napkins and blew her nose. She hoped no one noticed. Kate Beckett did not get sick. Ever.

She tried to continue but every line on the paper was becoming blurry and she could not properly see. She was trying so hard to concentrate that she did not even notice Castle coming behind her with two cups of coffee in his hands. She wouldn't have even noticed if he haven't laid his hand on her shoulder. It was so unexpected that it actually made her jump a little bit.

„Damn it, Castle!" Kate cursed quietly. How could he sneak up on her like that? She was a homicide detective, for god's sake. What was he even doing here?

„I thought i sent you home after we finished the case, shouldn't you be home with Alexis?" she remembered Castle telling her Alexis was going on a trip with her friends.

„Well... yes i think you said something like that, but since when do I listen to you? In regards of Alexis, I already tucked her in an hour ago, but somehow I knew you would still be here. By the way, I brought you some coffee." he handed her one of the cups. „Decaf." he chuckled when he saw the face she made.

„I brought it just for the road."

„Why do you think I am going home?" Kate asked, trying to cover her exhaustion.

„Because Ive seen you after we cracked the case and you looked like you could sleep on your desk if you weren't so stubborn about your colleauges seeing you asleep." he answered without a pause. Clearly he was expecing her fighting him.

„I've still got the paperw-" she started but didn't have time to finish that sentence because she sneezed again. Her head felt like it was going to explode at any minute now.

„Kate. You okay?"

„Yeah, fine." she could feel her fever rising slightly and tried to stand up but her vision just blurred a bit more and her whole body swayed to the side.

„Kate!" Castle exclaimed and caught her before she hit something. „OK, I am taking you home." he said with determination in his voice. She tried to fight him by saying that she was fine, but he just ignored her ranting, took the coat from the back of her chair and held it out for her. She saw the stern look on his face and decided that she was too tired to fight him. She put her hands into the sleeves and shivered a little when his hand touched her neck. If he noticed it, it didn't show on his face so she buttoned the coat and headed to the elevator. She didn't need to turn around to know he was right behind her. Just like always.

The next day:

Kate was lying on her couch, tangled in a fluffy blanket, almost asleep. When Castle drove her home the previous day, she insisted that she was okay enough to walk to her door by herself. Castle didn't look convinced but left... with a great concern visible on his face. It warmed her heart to know that he was worried about her. She could admit it, at least in her head. She dragged her exhausted body to her apartment and went straight for her bed. She didn't even take her clothes of.

The next morning she was feeling even worse than the previous day. She tried to go to the kitchen, actually got there after five minutes. She was hungry, but didn't have the strenght to make something complicated so she just took out one apple and ate it at the kitchen table. She wanted to lay down again but her bed felt like it was miles away from her so she just settled on the couch with one of the old blankets. She could feel the sleep pulling her under again when she heard a soft knocking coming from her front door. Who the hell would be knocking at... she looked at her fathers watch..11am!? Wow. She havent slept that long in a very long time.

The more persisnent knocking brought Kate out of her thoughts. It was probably just kid from her floor trying his pranks again, she thought.

„Go away" she tried to say. She was not sure if the kid even heared her, she could barely hear herself.

„Kate? It is me, Castle" Well, not the kid from the next door but kid nonetheless. That thought actually made her smile for the first time that day.

She dragged herself over to the door. Looking through the peephole she just wanted to make sure she wasnt imagining things because of her fever. But no. He was really there. What is he doing here?

„What do you want Rick?" She did not open the door, she didn't want him to see her that way. She knew she really didn't look very good right now and that it would just make him concerned about her. Or more concerned as it seemed. Gosh, how did this man manage to be sweet and annoying at the same time?

„I brought you some chicken soup and some lemons for limonade. By the way I thought that you'd like some company" she heard from the other side of her door.

He was just making excuses, he knew. He just wanted to see Kate again because he was worried. Last night she seemed really tired and he didnt want to wake her up so he tried to wait this morning. He really did but his writers imagination was going into overdrive imagining Kate lying somewhere on the floor unconcious. He knew he was being ridiculous but he couldn't help himself. Kate was his partner and he wanted to make sure that she was okay and didn't need anything. She was probably going to kill him if he just told her that so he will keep his mouth shut and show her what he bought.

His inner rambling was stopped when she opened the door. She looked worse than yesterday, he noticed right away. Her har was thrown into a messy bun, her skin a bit flushed from the fever and he could see a beads of sweat forming on her neck. His gaze travelled to her face. She looked a bit annoyed but she tried to hide her smile by biting her lip when she saw him standing there.

„Rick, what are you doing here?" she asked, her lips forming into a sleepy smile she could no longer contain. Gosh what that smile did to him. Even when she was clearly tired and sweaty, she was still beautiful and her smile could disarm him momentarily. Wait, didn't she ask something? Crap, she did.

„Uh... um.." he couldnt remember what he wanted to say, what excuse did he make up? Well... he will go with the truth and hope she wont kick him out. „Well, yesterday you looked like you had a flu or something so I thought I will just check up on you to make sure you had everything you wanted." he said and shot her a smile he knew will disarm her.

He was smiling. That cute smile that he reserved just for her when there was no one else around to see it. The smile that always made her heart flip in her chest and butterflies erupt in her stomach. She couldn't be angry when he smiled like that and he probably knew it. Damn him for being so damn sweet and caring... and cute. Wait...What? Since when did she think he was cute? Well.. probably since... the first day but that thought didn't have a place in her head right now. Not with an expectant look on his face and him still standing in the hall.

„Well, I can't reject my fauvorite ruggedly handsome writer when he brings me something." she said, her filter reduced bz the fever, and opened the door wider. He went around her and straight to the kitchen, speaking all the way there.

„You know, I could get used to you calling me ruggedly handsome, Detective." he said with a seducing glance thrown her way. That look... that look could make her knees turn to jelly. Damn him.

„Yeah, keep dreaming!" she tried to answer cheekily, hoping the breathlessnes in her voice wasn't so obvious. She came over to the kitchen saw him take something out of the bag he brought. „What did you bring?" she asked and tried to look inside the bag. He came in front of ber befoure she could actually see it's contents.

„Uh, uh, uh Kate," Castle said, smiling. „You go lie down and I will bring everything you might possibly need." he continued, already pushing her towards the door he thought her bedroom was behind. He wasn't completely sure because he has never been in that part of her apartment.

Kate couldn't help but smile and had her cheeky retort ready when she saw the door he was pushing her towards. She forgot that he has never been at her home since her last apartment blew up.

„Ehm... Rick. I know that sometimes I am a bit weird but, " she turned her head and looked over her shoulder, seeing him still pushing her with his hands on her back. She deciced to ignore the sparks his touch created. „I don't really want so sleep in my bathroom." she added. That seemed to stop him but only for a second until he let his hands fall to his sides. She didn't even have time to miss his touch because just seconds later she felt one of his hands on her back again and one under her knees.

„Rick? What the-" she didn't have time to finish that thought because he was already carrying her towards the door that was partially open and was hiding her bedroom. She tried to struggle but his strong arms just held her and he continued towards her bedroom.

Kate Beckett was in his arms. He couldnt quite believe it. How many times had he dramed of feeling the warmth that was radiating off of her? And now he had her. Maybe not the way he imagined, but it was still something. He expected more struggle coming from her and when there was second to none coming from her, he understood just how tired she must be. He carefully carried her to the bed and laid her down. Kate tried to cover herself in blanket but got tangled in it so he took it off of her completely.

„Hey!" she exclaimed. He just ignored the glare she was giving him and covered her properly. „Thank you, Mr. Nurse. If you would just leave my bedroom now and let me get some sleep?" she meant it to be cheeky but her sleepiness just sucked the bite out of her retort and all that came out of her mouth was little sigh, which Castle thought was utterly adorable. Not the word one would usually associate with Kate Beckett.

She hoped that Castle would just let her sleep now. Not that she didn't like the company or the care that he was showing towards her. It actually warmed her heart to know that he cared so much that he came just to make sure she was comfortable at her own home. He ran out of the kitchen but came back just a few seconds later with a soup.

„Really Rick?"

„Just eat it. You will see, it will make you feel better." he answered, smiling softly. He handed her a spoon and watched her as she slowly sipped the hot soup.

„Starring is still creepy, Rick." she mumbled between sips.

Rick laughed softly, happy that some things never changed. He remembered the first time she said that to him. It was years ago. How much has changed since that. The Kate Beckett from two years ago would never start dating him. This Kate lying in a bed that he sat at, this Kate could actually like him, or even love him one day. Wow, he was getting ahead of himself. But he could hope right?

He was almost startled when he felt a plate being pushed into his hands.

„Thank you Rick. The soup was fantastic." Kate said, smiling.

He smiled back and noticed just then that her skin was more flushed and was gaining some shades of red.

„Do you think you have a fever?" Castle asked with concern in his eyes.

„I dont know" she answered groggily.

„Do you have thermometer?"

„No."

He tried to think of some way that he could take her temperature. He looked around as if he expected some thermometer magically appear in the room. He tried to remember what his mother usually did when he was sick as a child. Ah, hand!

He noticed that during his thinking, Kate almost fell asleep. Gently, as not to rouse her, he laid his hand on her forehead. It was a long time since he did that with Alexis and he couldnt decide if Kate had a fever or not. He tried to turn his hand around and tried her forehead with the back of it. It didn't do much help. He couldn't think of anything else so he did the only stupid thing that came to his mind when it came to Kate. He kissed her.

Hand. She could feel a hand on her forehead. Then it dissapeared and came back again. Then nothing. She was almost asleep when she felt something soft touch her lips. It was warm and really soft, a feather like touch against her lips.

Rick. It was Rick! Lips?... oh god, yes... his lips indeed. He was kissing her? Why was he kissing her? Her whole body stiffened a bit. Rick must've sensed it because she opened her eyes just in time to see him leaning back, his face a bit flushed.

„What are you doing?" Kate said quietly. Even such an innocent kiss left her a bit breathless. What did that man do to her?

„I was just trying to get your temperature and I couldn't think of anything else..." he stammered sheepishly. Her whole body relaxed and she couldn't help but smile a bit at his cuteness. But he didn't see it as continued his rambling. „When I was a kid, my mother always did that when I was sick..." he continued. Kate decided to put him out of his misery and simply said:

„Rick." he looked up from his lap, where his gaze settled for a moment. „It's okay. Tell Martha that I really like her methods." Kate said with a sleepy smile. Rick chuckled and smiled softly, then he stood up.

„You should rest now, you still look very tired." He said gently. He didn't really want to leave but he understood that him getting away with kissing her was probably just because she was really tired and didn't properly register what was going on. He didn't want hr to regret anything and he wasn't sure he won't kiss her again if he stayed.

„OK" she hummed and put her head on a pillow. „Will you stop by later?" she asked shyly.

„Sure, if you want me to." Rick answered, his smile growing wider.

„Looking forward to it. But whatever happens, and i mean whatever, don't even consieder buying a thermomether" Rick let out little laugh and then left to let Kate have her well-earned rest. He felt that something changed today. He left with a smile on his face. He will see her tomorow again and hopefully, she will feel better and maybe let him kiss her again, this time for real.

Okay, so that's it. I hope you enjoyed this fic and please, if you see some mistakes, just PM me… English is not my mother language. And it would make me really happy if you wrote your opinion. Thanks. And this was supposed to be a one time thing but maybe I could write another chapter where Rick catches a flu from Kate and she takes care of him? Would you like that? Just review or PM me. Every review makes me happy.
