A/N Anddddd I'm back and it's also the final chapter for this story originally supposed to be a one shot but here we are four chapters later XD. Anyway thanks for reading and totally liking this story or at least I hope you did. I should be writing a new and improved Castle story. Remember I'm still learning and adapting to writing so... I apologize for the late update and don't forget to Read/Review

P.S: Sorry for the long authors note... Enjoy

"Dad you're back!" Alexis shouted from the couch she was sitting on with Martha and with that she stood up and starts walking towards him. "Did you tell Kate—" She stopped mid-sentence, and mid-step, when she had noticed that Kate was standing next to her dad.

"Woah, De ja Vu. She did the same thing earlier before I came to get you." Ricks whispers to Kate, which causes her to giggle quietly. "Since when does Detective Beckett giggle?"

Kate slaps his arm, "Oh shut up, Rick, and pay attention." They both listen to Alexis and Martha once again.

"And it looks like he brought a guest darling" Martha says with a knowing smile whilst walking up to greet Kate whom, she pulls into a tight hug "Katherine dear, how wonderful it is to see you again"

Kate who is now used to Martha's greetings, hugged her back enthusiastically. "Martha, it's great to see you too'' Then she looks over Martha's shoulder to see Alexis who has broken out of her reverie and starts to smile. Martha releases Kate from the hug and kisses here cheek before stepping away.

Alexis rushes to hug Kate. "Hey Lex! Thanks for inviting me over." before whispering in her ear "Thanks for giving your father a bit of a push in the right direction, he really helped me open up to him."

Alexis nods "My pleasure. I hoped my advice helped him." she whispers back ,so that her dad, whom she notices is craning his neck to hear what we were saying before looking away. "You're always welcome here Kate, I was hoping you'd come. Besides for you there is no invitation needed" Alexis replies out loud before releasing Beckett and stepping back. She noticed how her dad walked up to stand beside Kate and wrapped his arm around her waist. "And by the looks of it, I take it,that a bit of my advice worked" Alexis says while winking.

Kate and Rick both blush, "Now, Now Pumpkin. Your advice could have gone either way." Rick tells his daughter and Kate turns to bury her face against his shoulder.

"I know that dad, but by the way you and Kate are acting, and how you both blushed. I think it's safe to assume that something good happened to you two." Alexis replies before laughing at the two of them.

"Lex, stop teasing us. For the record, yes we're together. No we haven't discussed it properly yet. Also we haven't told anyone as yet." Kate says after she lifts her head off Rick's shoulder.

Alexis starts to laugh again, which causes the both of them to try and suppress their smiles from her antics "For the record" She emphasizes, "I didn't ask, but thank you for letting us know."

"You're welcome Pumpkin, we were going to tell you and grams first anyway. Now who's hungry, we got some food to make." Rick says while letting go of Kate and claps his hands.

"Why don't the two of you go freshen up." Martha tells the two of them

"Kate you can go first and I'll go after you. You can use my bathroom if you want. Also borrow my sweatshirt or tshirt or something to keep you warm if you want." Rick tells her.

"I think you still have some clothes you left over from the last time Kate. But if you need anything, I'll lend it to you." Alexis tells her.

"Thanks Lex." Kate grins.

Kate grabs his jacket from him as he walks past, Rick quickly tugs it off giving it to her, before heading off with Martha, to the kitchen. Beckett smiles and shakes her head before turning to Alexis. "Are you mad, at the new developments between your father and I?." She takes off her jacket also and walks over to hang it up on the coat rack near the door to dry.

"No? Why would I be mad. We were all hoping that it would happen soon, and well it did. I could see that my dad truly does care for you and it wasn't just a hopeless crush. Besides I'm glad it's you, just don't break his heart. Alexis replies before giving Kate another hug.

"That's good, I'm glad because you're important to the both of us and I wanted to know if you were okay with this." Alexis squeezed her tighter in response.

''Why don't you go freshen up and yell if you need anything. Your clothes are in Dad's closet in his room." Alexis let's her go to freshen up.

And that's what Kate does, she finds a pair of jeans she left behind that she's been looking for and borrows a blue sweatshirt from Castle. She goes to shower and dries her hair quickly before changing to join the Castle's for dinner. She walks out Rick's bedroom to find Alexis sitting on the couch flipping through the channels for something nice to watch. Once Alexis see's that Kate's back she switches off the TV and walks over to join her.

"All set?"Alexis asks her.

"Yep! Let's go help your dad, just in case he adds something extra, that he wasn't supposed to." Alexis laughs in response and leads Kate to the kitchen.

"A glass of wine Katherine?" Martha asks as they reach the Kitchen, she already has her own in her hand and is halfway through it.

"Yes please." Kate replies with a smile, her focus shifts to Rick and now Alexis who has joined in to help him cook. They're both standing near the stove but she can't see what they're preparing on it, because Rick is blocking it.

Martha hands her the glass of wine before turning to see what has her focus. "They're wonderful people and you do know that you're just as much part of the family"

"They're truly amazing, you included. I haven't met anyone like this, well not since my mother died. He brings out a part of me no one has seen, he makes me happy." Kate replies

"Well dear, let's toast to that. To family" Martha raises her glass near Kate's

"To family" Kate responds, clinking their glasses together and takes a sip.

Alexis turns around to face them, "Would you like some wine darling?" Martha asks her.

"No thanks grams, I'm good." Alexis replies

Martha and Kate share a look before laughing. Martha composes herself first, "Richard dear, are you sure she's yours? She's absolutely nothing like us."

Ricks laughs from where he's standing near the stove, "Last time I checked, I'm pretty sure she is mother."

Kate watches as Alexis groans and then whispers to Kate "They do this everytime."

Kate giggles and Alexis joins her "well maybe you should, accept it next time and shock them." She whispers back.

Alexis gives Kate a feed the birds motion, "Maybe I should, I wonder what their reactions would be?" She says in a thoughtful tone.

As Beckett was about to reply Rick calls Alexis to come and check to see if the food is ready. She shoots Beckett an apologetic look before turning around to help her dad.

Kate and Martha continue to have a conversation with Rick and Alexis chiming in at some times.

Alexis then goes to set up the dining room table which Beckett helps her with. Once the food is done Rick excuses himself to go freshen up and sort himself out. When he comes back. Kate swears he never looked cuter in his faded jeans and sweatshirt and his hair without gel, which makes it flat. After a quick kiss from Beckett and Castle. They all sit down for a dinner that tasted divine and a room filled with love and chatter. There was never a dull or silent moment in that time.

After dinner when the place was cleaned. Which everyone helped to do, Alexis and Martha went to bed leaving Castle and Beckett to be left alone.

"Finally a moment to ourselves." Rick says with a grin before drawing Kate in close to kiss.

"Very eager to get me alone Castle." Beckett replies before pulling him into a deep kiss.

"Yeah well, we needed privacy to do that. You look pretty cute in my sweatshirt by the way." Rick replies breathlessly near her ear. He shifts his arms so that one hand is on her waist and the other is drawing circles on her lower back.

Kate nibbles on his ear " Why thank you, you don't look as half bad yourself. But on an important note. We need to discuss somethings first."

Rick moans "Well would you like to discuss it in my bedroom, I'm sure a lot of future meetings will happen there. Might as well get a head start." And with that he starts kissing down the underside of her jaw all the way to a sensitive spot on her neck. Where he starts to bite and suck, which brings out a moan from Kate

"Castle, babe focus. What are we going to tell everyone?" She says breathlessly wondering how he managed to find the sweet spot so quickly.

"Babe?" Castle stops his movement to look at her. Before he let's out a huge grin "I like it" he says before pecking her lips quickly before continuing his movements from before. "I am focused" he tells her

"Focused on marking your territory on my neck" Kate teases

Rick pauses to look at his handiwork, yep he did good. "We'll tell them when ever and whatever you want to tell them. It's up to you."

"You're so sweet, maybe we should keep it a secret for now. Cause if anyone at the Precinct or Montgomery had to find out..." she trails off

"Then we won't be able to carry on what we're doing without consequences" Rick finishes for her. "I'll stop shadowing you, that's if you want me too. If it means that it will be easier for you and for us."

"NO!" Kate softly shouts at him. "Don't you ever stop shadowing me because of that. We'll take it one day at a time and when the time comes well, we'll figure it out like we always do."

Rick nods in agreement "I think we should tell your dad first. And then Lanie, Ryan and Espo."

"Yeah I'm going to tell him in the morning, maybe you could come and visit him with me if you would like?" She asks him

"I would love to" he replies before Kate kisses him.

"I say, we mess with Lanie, Espo and Ryan for as long as we can before they find out and then see who finds out first." Kate says

"My, my, my Miss Beckett, who knew that you were so evil and naughty." Rick says in a husky voice

"Well take me to your bedroom and I'll show you how naughty I am." She whispers back seductively.

With that Rick leads her to his bedroom whilst kissing her and her returning the kisses. Luckily they don't bump into anything on the way. Once inside with the door shut and locked. Their night became filled with the throws of passion and love.

On Monday when it was time to go back to work. Kate's body was littered with bruises and hickies, of Rick marking his territory. Most of them covered by her clothes and a few that had to be covered with makeup. No one had notice that she was walking a bit funny.

Rick wasn't as bad as Kate. But she did mark her territory as well.

When they arrived in the morning separately of course. Everyone noticed the smiles from Kate and they both were in a good mood.

Rick left to go get Kate her coffee and when he came back and handed it to her she saw the heart that the froth formed was on top. He winked as he gave it too her and she blushed a little bit.

That's how they spent the rest of the day when they weren't working on the case. They were finding ways to tease and make each other blush. Sneaking kisses when they were completely alone

Her team as well as Lanie were oblivious as ever...
