Chapter 4 Castle`s rules

It was a week since Alexis and Kevin had told Castle about their relationship, and he still wasn`t completely on board with it yet. He pretended like nothing when he worked with Kevin. Kevin did the same. Alexis had spent the whole week at Kevin`s place, Castle had barely seen her. He didn't like it but he didn't say anything. She is an adult, able to make her own decisions. Even if he might not like those decisions.

It is a new day at the precinct. A new case to work on. A new murder to solve. This time a man thrown of a rooftop landing in a three. Castle went with Laney back to the morgue, riding in the back of the van, when suddenly the van stopped like it crashed, and they got thrown out of their seats. The back door opens and someone is pointing a gun at them, snatches the body out of the van and disappears in a black car. The men had masks on. It all happened so fast it was almost like it didn't happen. "Is it just me or is that really, really weird?" Castle says looking at Laney. Back at the precinct Laney are checking that Castle is alright from the incident. "Well?" Montgomery says walking up to them. "He`ll live." Laney answers and pinches Castles ear. Esposito and Ryan are walking up to them also. "What, no brain damage?" Ryan says putting his hands in his pockets and smiles. "If he has some, it happened way before tonight and was probably self inflicted." Laney says crossing her arms over her chest. "Ha, ha." Castle says. Ryan and Esposito smiles. "How`s Lois Lane?" the captain askes turning to face the two detectives. "Who? The reporter? We took her statement and we sent her home. We have an APB on the sedan, CSU`s are combing the roof tops and we have units looking for surveillance from the crash site." Ryan tells his captain. "You know what I don`t get? Who would steal a dead body?" Esposito says. "Oh, plenty of people. Organ harvesters, cadaver less med students, Satanists, mad scientists looking to create their own monster." Castle says. "Or the guys who killed him might have left some evidence behind." Beckett says from behind him. He turns around and look at her. "Boring." He says and turns back around to face Ryan and Esposito again. After hearing some more of Castle`s crazy theories Beckett, Ryan and Esposito goes back to doing real police work. Beckett and Castle goes to ask the victim`s wife some questions. After that, day go home for the night.

Castle walks in his front door and see both Alexis and Martha there. "Dad. Thank God you`re home. Are you ok?" Alexis says running up to him and embrace him in a hug. "I`m fine, why?" Castle asks looking down at her. "Fine?! Mess, body snatchers, gun men. I texted you like a thousand times." Alexis says. Relived that her father is ok. "Sorry, my phone must have been of. How did you know?" Castle asks picking his phone out of his pocket. "Beckett called." Alexis answers. "Really!" He says with an amused look on his face. "She just wanted to let us know you were alright." Martha says. "Ehem" Castle mumbles walking to his office. "So, was it awful, were you scared?" Alexis asks after entering his office after him. "Me? Scared, no come on. Excuse me while I change my shorts." Castle says looking at his phone. "Dad." Alexis shakes her head. "No, I was scared, but all they were after was the body." He says. "Why?" Alexis asks. "Why indeed." He says, looking at Alexis. He opens up his messages on his phone and read the messages from Alexis out load. "Dad, where are you? Dad, are you ok? Dad, call us right away. Dad, can I go see Fame with Kevin on Friday?" He looks at Alexis, she just smiles back at him. "Your concern is touching." He says. "That one was after I knew you were alright." Alexis defend herself. "But I thought we were going to see that together." Castle says putting his phone away. "We will and we still can, but he invited me to go see it with him on Friday. Alexis says and flashes her eyelashes at him. "You rather go with your boyfriend than your dad, what`s wrong with you?" Castle sounds a little disappointed. "If you really want me to go with you, I will." Alexis says. "No, you tell Kevin he won this round, but I got dibs on Christmas carol." Castle says pointing his finger at her. "Thanks dad. I`m glad you weren`t killed by body snatchers." She stands up and kiss him on the cheek before turning around and leaving the room. The day after at the precinct they interrogated a possible suspect, but it didn`t lead anywhere. A little later they got a phone call that someone had found the body, again. When they came to where the body was, Laney could tell them that someone had operated on him and removed all his organs. That leads them to the conclusion that he had been a drug mule. On Friday after a lot of investigating and interrogation of different people they are able to make a connection to the Russian mob. Castle goes undercover in a under ground poker club and they get the person responsible for their victim`s murder. They close the case and go home for the evening.

Kevin goes over to Castle`s loft, instead of going home to his own apartment. He`s there to pick Alexis up for their movie date. Kevin knocks on the door to Castle`s loft, and after about two minutes Alexis opens the door for him. "Hi" She says smiling at him. "Hi yourself." He says leaning down and kiss her. A long kiss filled with a lot of longing and passion. "Ready to go?" He asks when they break the kiss to take a breath. "You look beautiful as always, by the way." He says and kiss her again. "Thanks. You look pretty hot to." She looks him in the eyes. "Yes. I am ready." She says after a minute of silence, just looking at him. Then he takes her hand, entwining their fingers and they walk together to the elevator. They kiss again when they get in the elevator and don't break apart until the elevator door opens, and they walk out.

After the movie they go to this ice cream place and orders ice cream. They sit and talk and eat ice cream for about two hours, before Kevin drives Alexis home. They say goodbye in the car this time. They`re both very tired but agrees to meet up again tomorrow. "Maybe you can come over and we can spend some time at the loft with my dad. That way he can see how good we are together. Maybe that will make him a little more understanding. Make him more ok with our relationship." Alexis say on her way out of the car after kissing Kevin goodbye. "Ok, we can do that. See you tomorrow. Love you," she can hear Kevin say right before the door closes. She smiles and wave at him before she turns around and walks inside the building.

Alexis wakes up early the next morning, she is not able to fall back to sleep so she decides to take a morning run. She gets up, puts on some sweatpants, a sweatshirt and running shoes, walk down the stairs and in to the kitchen to fill a bottle of water before she walks out of the loft and out of the building and starts running. One hour later she comes back to the loft, and see her dad standing in the kitchen when she walks through the front door. "Good morning dad." She says coming in to the kitchen. Castle looks up from whatever he is doing and smiles at her. "Good morning sweetheart. Did you just come in the front door?" He gives her a kiss on the cheek when she gets closer. "Yes, I woke up early and decided to take a morning run." She smiled back at him. "I am making eggs and bacon for breakfast. Go take a shower and the food will be ready when you get back." He says to her. She turns and walk out of the kitchen and up the stairs to her bedroom.

Half an hour later Alexis, her father and Martha are all sitting down at the kitchen counter eating breakfast together. It doesn`t happen often anymore, they all are too busy. "This is nice. I mean we never have time for breakfast together anymore. I`ve kind of missed it. The food is great dad." Alexis says taking her last bite of bacon. "Yeah, this is nice. We should try and do it more often. Maybe we could make it to a regular Saturday routine." Castle says standing up and walking to the dishwasher with his plate. "I totally agree." Martha says before she to stands up to put her plate away. Alexis is finally done eating and stands up and walk to the dishwasher to. All three of them sits back down a little later with a cup of coffee each. "Do you have any plans for today dad?" Alexis asks looking at her father. "No, not really, Nothing special. Why?" He says looking curious at her. "Good, then you are here when Kevin comes over later. I think it will be good for you to see us together. It might help you see things clearer. And it will be good for the two of you to get to know each other outside of the precinct too." Alexis says standing up and walking to the sink, putting down her now empty coffee cup. Castle turned his head and looked at her. "Kevin is coming here. When? Why?" He says. "Yes, he is. Soon. Because I invited him. You always complaints about me spending too much time at his place, so I thought we could spend some time here for a change. Is that ok with you?" Alexis says. Just as she walks out of the kitchen she hears a knock on the door, and she immediately knows who it is. She goes to the front door and opens it with a big smile on her face and greets Kevin with a kiss while grabbing his arm and drags him inside before closing the door. They stay there kissing for some time until they get interrupted by Castle clearing his voice. They break apart and take one step away from each other, and look at Castle. "Hi Castle." Kevin says extends his hand to him. Castle takes his hand and shake it. Greeting him. "Hello Ryan." He says and let go of Kevin`s hand. "Please call me Kevin outside work." Kevin says and entwine his fingers with Alexis`s. Alexis leads him in to the living room and towards the couch. They sit down, still with their fingers entwined. They`re sitting close, to close for Castle`s liking. He followes them in to the living room. He sighs, but he doesn't say anything. He just observes them. Their hands are no longer entwined and Kevin puts his hand on Alexis`s thigh. Alexis seems to be used to it. That bothers Castle. "Do you need to touch her like that in my presence?" Castle asks looking directly at Kevin. "Sorry." Kevin says removing his hand from her thigh. "I will do my best to respect your wishes and boundaries in your home Castle. But just remember that we are in fact a couple." He says meeting Castle`s eyes for a moment. "Good. Until I am a bit more comfortable with you two dating I want to put down some rules. No making out or intimate touching in front of me. No sex under this roof. No dirty talk to each other." Castle says sharply, looking at both Alexis and Kevin at the same time. "Really dad." Alexis sounds a little angry. "Ok, fine by me. I can play by those rules." Kevin says shaking hands with Castle. Eventually Castle stands up and leaves the living room, leaving Kevin and Alexis alone. Alexis sighs. "Shall we go to my room and make out?" Alexis says flirtatious. "It`s tempting. But I don't know if your dad will appreciate that." Kevin says. But still he stands up from the couch and follows Alexis out of the living room and up the stairs. When they are inside her room and the door is closed, Kevin`s lips find hers and he push her up against the door. They stay there kissing for a while until they need to break free to get some air. "Wow" Alexis says winking at him. "You liked that?" Kevin winks back. "You have no idea how much I actually want you right now. I can`t believe you agreed to Dads rules." Alexis says before she captures Kevin`s lips with her own. Kevin breaks the kiss for a moment, look her deep in the eyes. "I love you, Alexis. He is your dad, and this is his apartment. He needs more time to come around to us dating, and it is only fair to give him that. He could have banned me from coming here, from seeing you. That would have been so much worse." Kevin says before he kiss her again. His lips find the way down to her neck. They jump apart when they hear a knock on the door and Castle`s voice. "Alexis what are you to doing in there?" They move away from the door, and Castle opens it and walks inside. "I just wanted to show Kevin my room. There isn't anything wrong with that, is it? And since you asked us not to make out in front of you, I figured we could do it in here." She says to her father while looking at Kevin. "I am 19 Dad, I am an adult and if I want to make out with my boyfriend, that`s what I`ll do, no matter what you say." She said this time looking straight at him. Castle sighs and without saying anything he turns around and walks out of the room.

A few hours later Kevin and Alexis sat down at the kitchen table with Castle for some lunch. Castle was an ok cook, and the meal was simple, but good. They talked about books and food while eating. After an hour they were all finished eating and moved in to the living room to watch a movie together, all three of them. Martha was not home. When the movie ended Alexis suggested to play Scrabble. They did. When they stopped playing a couple of hours lather Castle had won every time except one. And of course he couldn't shut up about it. The more time Castle spent with Alexis and Kevin as a couple, the more he realized how perfect they were for each other and how much they really loved each other. The way Kevin looked at Alexis showed him that Kevin truly loved her. He couldn`t fake that. The hardest part for Castle was admitting his little girl was not his little girl anymore. He was no longer the most important man in his daughter`s life. He had to admit to himself that Kevin was good for her, and that there were worse guys than him she could have been with. But he still had a hard time accepting it.

Around nine in the evening Kevin decides it is time to go home to his own place and Alexis decides to go with him. Kevins apartment has become like a second home for her and she really likes it there. The fact that they would have more privacy there made the decision even easier. She wanted to have sex tonight. That would not happen if she stayed at the loft. She packs a bag and says goodbye to her father and grandmother before she follows Kevin out the door in to the elevator and out to his car. Gentleman as he is Kevin opens the car door for her to get in before he goes around the car and get in on the other side. The drive to Kevins apartment takes about ten minutes. Alexis turns on the radio and sings along to a song by Taylor Swift. Kevin watches her with an amused look on his face. She is so sexy, he thinks. Her amazing voice fill the car and Kevin feels like he is hypnotized. She has that affect on him. Her voice is the most beautiful sound he knows.
