A/N: I had a random idea, and this fic was the result. It's definitely going to have Caskett in later chapters! Please review! :)
Disclaimer: I don't own Castle, nor will I ever.
Beckett glanced up from the file she was reading to look at Castle's pleading face. "No."
"Castle, I said n—,"
"But you have to!" He cut her off.
"I do not have to do anything." She said, narrowing her eyes at him. "Now go away. I'm busy."
"I'll go away if you agree to go to the launch party with me." He said, grinning his boyish grin.
Castle made a sudden wild grab for the file she was holding and successfully snatched it from her. He put it behind his back and began backing away from her desk.
"Castle, what the hell! Give me that!" Beckett yelled. She pushed her chair back and stood up, walking towards him briskly.
"You can have it if you agree to go." He said, smiling.
Beckett made a grab for the file and missed by centimeters. Castle hopped over a chair and around a desk. He held the file in front of him. "All you have to do is say yes, Beckett. Just one little word."
Kate nearly growled. "Give me the damn file or I'll throw you in jail for theft." She threatened.
"No matter. I'll just get Alexis to bail me out." He smiled. "Again." He waved the file at her and she made another grab for it, and missed yet again as he pulled it out of her reach just in time.
"Castle!" Kate yelled.
She pushed the chair out of the way and ran around the desk. Castle took off running with her hot on his heels.
"CASTLE!" She yelled again. "GIVE ME THE DAMN FILE!"
Castle made the mistake of looking behind him to see how close Kate was. Since he wasn't watching where he was going, he didn't see the chair right in front of him. That is, until he ran into it.
With his arms waving like mad, Castle tripped over the chair and fell to the ground, flipping in the process and landing on his back. Beckett, who had not expected him to fall, felt his leg knock hers out from under her and down she went, landing right on top of the author.
After a few moments of lying there in a sort of dazed confusion, Castle spoke.
"You know, Katie, I always imagined that I would be the one on top." He grinned. "But I suppose you are a control freak."
Beckett glared at him and smacked him hard enough to make him wince in pain and mutter an "ow". She quickly stood up and straightened her clothes, also grabbing the file that had fallen out of Castle's hand when he fell. Castle continued to lie on the floor and watch her, that stupid, irritating, smile still plastered on his face.
Kate couldn't resist. She pulled her foot back and kicked him in the thigh. He grimaced and cringed again, and she smirked. "Call me Katie again and next time I'll send you to the hospital."
Castle watched her walk away from him and then sighed. Esposito, holding a cup of coffee, walked towards him. He raised an eyebrow.
"Do I want to know?"
Castle grinned. "Probably not."
Esposito nodded and walked away. He was sure that if it involved Castle lying on the floor grinning, he didn't want to know.
Castle sighed, and stood up. He straightened out his clothes and glanced towards Beckett, who was now sitting at her desk reading the file he stole from her. He really wanted to convince her to go to the launch party with him. He wanted to show off his muse. Maybe stealing the file from her wasn't the best way to get her to agree to go.
So, it was time for Plan B. He was changing tactics entirely.
He headed towards the espresso machine and filled two cups with hot, steaming coffee. Then he made his way over to Beckett's desk and sat down in the chair he had been occupying before the chase had started. He sat one cup of coffee down in front of her.
Kate glanced up at him and then the coffee. "What is that?"
"That, my dear, would be coffee."
Beckett glared at him. "I know that. I mean why are you giving it to me."
"Can't I give my friend some caffeine?" Castle asked innocently.
"I'm not your friend, Castle."
"Fine then. Can't I give my mu—inspiration some coffee?" He asked, smiling his most charming smile.
Castle raised an eyebrow. "Don't be so cold, Beckett. I'm just trying to do something nice for you. No need to be so defensive about it."
Kate opened her mouth to reply, but then decided against it. She just rolled her eyes and turned to her computer, trying to ignore him.
Castle sighed. And then he sighed again, more dramatically. "I guess I'll have to go to my launch party all alone then." Kate saw him shake his head out of the corner of her eye. "It's such a shame too. I think you would really have some fun."
Beckett had to bite her lip to keep from replying. The truth was, she wouldn't mind going to the launch party. She liked to dress up. It was a nice change and it made her feel more feminine. She was a cop, so she had to be professional. Plus, chasing after murderers wearing a skirt and stiletto shoes just didn't seem like a good idea.
But she didn't want to have to socialize with people. She wasn't a people person. She wasn't social. That was probably why she never got a second date. Kate Beckett liked what she knew. This launch party was unfamiliar territory and she hated being out of her comfort zone. Sure, Castle would be there, but she would be on his turf. She just didn't think she was ready for that.
"I highly doubt that, Castle." Damn, she hadn't wanted to reply. Oh well, what's done was done.
"Why won't you go?" Castle asked. He leaned forward, elbows resting on her desk. "Give me one good reason."
Kate sighed and turned towards him. "Well, for one, you just made me chase you around the precinct to get my damn file back."
"Okay, that one doesn't count." He said. "Why didn't you want to go before I stole your file?"
"Because I don't." She crossed her arms stubbornly.
Castle cocked his head to the side as he scrutinized her with his eyes. "You're afraid." He stated.
Beckett's eyes widened ever so slightly, and she hoped that Castle hadn't noticed. "Afraid of what? A bunch of blonde bimbos worshipping you? No, I don't think so."
"Ouch, Beckett, that hurt." He said, putting a hand over his heart and pretending to be in pain. "Plus, the only bimbo that's going to be there is my ex-wife Gina. She is my publisher after all."
Kate rolled her eyes and tried to get back to work. But Castle just wouldn't let her.
"You still didn't give me a reason." Castle said. "Just one reason, Kate. One honest reason about why you don't want to go."
"Because I just don't, okay? I don't have to have a reason." She said.
This argument was getting really old really fast. Castle just didn't give up.
"I'll even let you call me kitten."
Kate's eyebrows shot up as she looked at him. She couldn't hide her slight smile. "And I'm supposed to go just so that I get to call you kitten?"
"Yes." Castle said. "And I promise that I won't leave you alone, if that's what you're worried about."
"I'm not worried about anything, Castle." Beckett said sharply. She could tell that he saw through her lie.
"The party starts at seven." Castle said, smiling at her in a knowing way. "So…pick you up at six-thirty?"
Kate sighed and looked away from him. What the hell was she getting herself into? "You owe me for this, kitten."
Castle just grinned.
