Castle walked into the bullpen and spotted Beckett at her desk sat eating some skittles from the bowl she kept on her desk.
"Good afternoon Beckett." He said sitting down in his chair.
She smiled at him and stopped what she was doing. "Good afternoon Castle."
"So where do you want to go for lunch today?"
"I think I'm in the mood for something quick. Maybe a sub."
"Okay then. Just remember not to get to much because I'm cooking dinner tonight." He smiled.
"Yes what are we having?"
"That would be spoiling the surprise."
"What is it with you and surprises?"
"Nothing I just like you to be astonished and amazed."
"Well you don't need any help with me being that you amaze me every time you act responsible."
He laughed. "Why you flatter me so."
"I know I'm to kind to you I think."
Castle stood up along with Beckett, they yet again stopped and asked Ryan and Esposito if they wanted anything bringing back. They declined and then went back to trying to get a paper ball through the hoop on the bin they had put on it.
Beckett stepped into the elevator followed by Castle as soon as the doors closed Beckett grabbed Castle and crushed her mouth to his. They broke apart a few moments later and Castle stared at her.
"Wow."
"You have no idea how long I've waited to do that." Beckett told him.
"Just a quick question. We're at work so why did you just do that."
She smirked. "Oh don't worry that elevators don't have camera's in them so we're safe."
"Right then." He nodded. "Not that I'm complaining of course." He smirked.
"Oh no, because you never complain." She smiled with him.
They elevator stopped and they got off walking outside and down the road to the sub shop that they usually went to went Beckett was in the mood for them, with Castle and Beckett standing close together Castle resisted the urge to hold her hand. As much as he wanted to they were in public and they hadn't exactly come out about the newly formed relationship yet.
"So is Alexis and Martha in for dinner tonight?"
"Alexis is, my mother is going to stay with Chet."
"Well it should be a fun filled night then. What's the plan?"
"I was thinking maybe dinner, and then some board games." Castle grinned like a 5 year old.
"Got any good ones?"
"Monopoly is always a good one. Besides I have yet to meet someone who can win me, although I don't know if Alexis lets me win because she gets bored."
"Well I'm quite good at monopoly Castle and I bet I can beat you hands down."
"Well you're on then." He smirked.
They both walked through the doors of the sub shop and walked to place their order smiling.
Later that evening Castle was just finishing making their dinner when he heard a doorbell ring.
"I'll get it." Alexis raced for the door and opened it with a smile. "Good evening Kate."
"Evening Alexis." She smiled.
They walked in and immediately started to talk, Castle watched them and smiled to himself. He grabbed a glass from the kitchen and poured a drink for Beckett and took it to her and she sat down on the settee.
"Here you go." He gladly gave it to her.
"Thank you." She took it out of his hand smiling and then turned back to Alexis. Castle then went back into the kitchen.
"So what's on the menu tonight?" Beckett asked.
"I think chicken curry."
"Well it sure smells nice."
"Dad's cooking always does." Alexis smiled.
Castle started to set the table up and Alexis excuse herself to go wash up. Beckett walked into the kitchen and smiled at Castle, he was so domesticated. Unlike some of the other men she had met in her life. He went and pulled her to him, she settled the glass down on the counter and put her hands around his neck.
"So I was thinking maybe we should tell Alexis about us tonight." Castle said and stared at her.
"You think she already knows though?"
"Well she probably does but I'm sure hearing it from us will make her day."
Beckett laughed. "You're right it probably will."
He gave her a kiss and released her so that he could get the rest of their dinner ready. Laying it out they sat their and started to dish it out. Beckett ate a forkful and smiled in appreciation.
"This is really good Castle, why can't you cook like this all the time."
"Well thanks, and I don't really get time to cook all the time but when I do it's really good right pumpkin."
"Well I don't know about that dad, it's not always good."
"What do you mean not always good."
"Exactly what I mean." She looked at Kate. "If he ever wants you to try new food for him don't he has an obsession with trying to make 2 things go together that just shouldn't."
"Hey if this is about the smorlette I made the other day it was really good."
Beckett looked at him. "I'm sorry but what's a smorlette."
"It's on omlette and a smore in one." He grinned.
"So you actually put chocolate, marshmallows and a graham cracker in an omlette?"
"Well yeah, have you never tried it."
"No Castle I can honestly say I haven't."
"Well you should they are amazing."
They made light conversation while eating until the end, Castle had just cleared up the plates and put them in the dishwasher when he sat back down with Beckett and Alexis.
"Hey Alexis can me and Kate talk to you for a minute."
"Sure dad what's up."
"Well we thought that you should know…" He stopped and looked at Beckett.
"Know what?"
"Me and your dad are dating." Beckett finished for him smiling.
"Really? I thought you were ages ago. But I'm so excited for you guys."
"See Castle I told you." She stared at him and chuckled. "Can't get anything past her these days."
"No but it's sure fun trying." Castle laughed. "So who's up for a game of monopoly."
"Oh me, and I am so going to win you this time." Alexis grinned.
As Kate lay in the arms of Castle that night her mind thought back to how great the evening had planned out. She remember how Alexis and her had teamed up to win Castle at winning monopoly, and then how he had sulked like a kid after losing. How they'd all sat and watched TV afterwards like a real family should. Then she remembered how when Alexis had gone to bed that night she had pulled her into a hug and told her how happy she was that she was finally dating her dad. As she lay there staring at the wall she realised that this was what she had been searching for all along. Someone who would love her and welcome her into their family, and that's exactly what Castle had done.
She turned over and got closer to Castle, his arm tightened around her waist and she put her head on his chest. She lay there for a little longer just listening to the sound of his heartbeat. She inhaled his scent of him that she loved so much and then finally she closed her eyes letting sleep take over her.
