Disclaimer: I do not own Castle, sadly. I'm stuck writing things like this.
It was around midnight when Kate heard a knock on her door. She looked up from the pasta she'd just heated up and walked to the door, glancing at the gun on the side table. She looked out the peephole but saw no one. She picked up the gun and cocked it, sliding open the door slowly. She put her foot out, and turned to the right, aiming at the closest thing she saw, which ended up being a him rather than an it. Kate lowered her gun and walked back into her apartment.
"Damnit, Castle!" She put her gun on the table it was previously on, and Castle closed the door behind them.
"Paranoid much?" He muttered. She turned to him and glared, causing him to hold up his palms in defense, "Okay, not paranoid, just kidding!" Kate walked back to her pasta and resumed eating it, as he stood there awkwardly. After a few minutes, she looked up at him.
"What?" She snapped.
"Nothing, sorry.." Their eyes were locked on each other for a few seconds before she sighed and put her fork onto her plate.
"Alright, start talking."
"Excuse me?" He looked at her in confusion and she tilted her head.
"Why are you here at-" She glanced at the clock, "midnight on a Tuesday? Is it Alexis? Is she okay? Is Martha?" Her eyes widened and she started to get up, but Castle responded quick,
"No, no they're both fine, I promise." She sat back down, still looking at him.
"Okaaaaayyyy… Then why are you here?"
"What, you're not absolutely delighted to see me?" Kate rolled her eyes and picked up her fork.
"Can I show you something?" He looked at her for a minute, but didn't wait for a response before grabbing her hand and leading her towards the door.
"Castle, I'm eating, what are you doing?"
"I'll buy you dinner." He answered quietly. Kate looked at his face but couldn't find any emotion. How could someone like him go from fun to emotionless in two minutes? He was Richard Castle, five-year-old in the body of a 40-year-old.
"It's midnight, nothings open." Castle ushered her to the door, opening it and putting her jacket on for her. He put his hand on the small on her back and they walked out.
Waiting for the elevator, his palm still rested on her back, but when it opened he let it fall. They walked in, and she turned to him to ask what was wrong, but gasped when she felt his arm snake around her waist and his hand touch her cheek. She knew she should pull away, but instead wrapped her arms around his neck and mashed his lips against hers. They both sighed into howright the kiss felt. Wait, Kate Beckett kissing Richard Castle? It felt right? Kate sighed again as tons of thoughts raced through her mind. The elevator opened and Castle had to literally pull on Kate's hand to get her to move from the spot she was standing in. They walked to Castle's car, with his arm around her waist.
Not a word was spoken during the car ride to Castles house. Once they'd gotten to his house, Castle opened the door with his arm wrapped around Kate's waist. The silence continued when a few minutes later, Kate was not only staring at hers, but the faces of everybody involved in her mother's case. She walked out of his grasp and leaned against his desk. Kate blinked back the furious moisture in her eyes, picked up the closest book to her, and chucked it at Castle, which was dodged.
"That is my mother's case, Castle! You had, have, no right to go behind my back on this case. It wasn't okay before, what do you think changed? You think that you can just tell me that you love me and decide to take my mother's case? How long has this been going on?" Castle looked at her with his jaw dropped and sighed. She knew? She knew he told her that he loved her and she didn't say anything? His eyes drifted back to Kate's when she whispered, "how long Rick?"
"Since you were shot.." He closed his eyes and looked up, but they shot open when he heard Kate laugh. She was halfway to the door when he looked at her. "Kate!"
"How could you?" She spat, turning to face him.
"I was trying to keep you safe, Kate! When are you going to understand that everything I do is to keep my mother, Alexis and you safe? If I let you keep going on this case you would have ended up right back where you started! You would have pushed me away and fell into it, just like you did all those years ago and honestly Kate, I don't think I would have been able to do it! I don't think I could watch you dig and dig to find out what? Everything we already know? I can't watch you fall into this case and I don't think you could handle it either!"
"You were supposed to be there for me! It's not about me, or you keeping me safe, it's about my mother! It was her case, and I asked you to stay out of it! I asked you because I knew that by you being involved would only increase your chance of getting hurt, and Rick, I can't watch you get hurt because I couldn't solve the murder that basically defines me!"
"Kate, I'm not getting hurt I'm fine."
"You won't be," Castle didn't respond, he just looked in her pleading eyes and sighed, letting the hand that was on her shoulder fall to his side.
"I'm sorry for going behind your back, I'm not sorry for doing this," instead of answering, Kate turned and walked out of Castle's office and towards the front door. She put one hand on the knob and twisted, but instead of walking out, she walked into something hard. She looked up and into a pair of big blue, concerned eyes.
"Detective Beckett."
"Alexis," they stared at each other for a few moments before Castle came out of his study, not hearing the door shut. Kate muttered a low excuse me, and made her way out of the door, and to the elevator. Pressing the button, and watching the doors close in front of her, she leaned her head against the cold metal of the wall.
A/N: Okay guys this is what I have so far! I'm not sure if I like it, or if I want to continue on considering I have no idea where I want to go with it, but let me know what you think and if I should continue, and where you want to see it go and I'll do that!
Any spelling/grammar mistakes are mine!
