Staring at the couple in front of her, Alexis smiled as they continued to look at each other, pulling faces at each other before laughing hysterically. She couldn't help but love the sound of her father laughing with the woman beside him, she loved the happiness she'd brought to the family and the fact she was giving her a brother and sister finally but she couldn't help but think that something was wrong.

"Are you going to tell me what's going on?" Alexis asked causing them to both look at her and bite their lips, wishing they were better at keeping things from the intelligent young woman. "Right now I know something's up, oh my god are you having twins?" she asked before Kate quickly shook her head, her hand quickly resting on her bump as she smiled down at it, enjoying the feel of it under her hand.

"No there's still only one in there I hope, I can't imagine have three children to deal with, I can imagine actually the baby would be easier to deal with than your father" Kate explained as she turned to look at Rick who stared at her before sticking his tongue out, gaining a quick eye roll from her in response. "But your father does actually have something to tell you" she muttered causing him to open his mouth to answer back quickly. "Don't you Rick" she laughed as she clutched onto his hand under the table, giving it a quick squeeze as she continued to smile at him.

"Yes, Alexis you know how much I love Kate and that she makes me happy" he whispered as the teenager quickly nodded, knowing her father was treating her like a young child once more with what he was saying. "Well we're making it official and are getting married" he declared, the squeal from the teenager quickly informing the two adults that she was happy about the event. "Not until after the babies born though" he whispered as Kate nodded in agreement, her hand quickly resting on the table knowing that Alexis would want to see the ring.

"Wow its beautiful Kate" she quickly commented as she looked down at the small diamond resting on the woman's finger. "Good choice dad you did well this time, didn't choose something ridiculously ugly" she laughed as he rolled his eyes, Kate glancing at him as he shook his head and sighed.

"That's a story for another time it's too much for one night" he whispered before leaning over and kissing her gently as Alexis watched them, a smile covering her face as she thought about how one day she'd hope to find someone who'd make her as happy as Kate made her dad.

XOXOXOXO

Creeping up the stairs, she walked down the corridor and slowly stopped outside the teenager's bedroom, breathing out slowly before she knocked on the door gently, waiting for a response.

"Come in" she heard Alexis call before she pushed the door open and entered the room to see her lying on her bed with her book resting on her thighs, staring down at it as she continued to bite her lip. "Hey Kate" she muttered as Kate slowly entered the room and sighed, watching as Alexis patted the empty space of her bed, allowing Kate to sit down and sigh. "What's wrong?" she asked.

"I just wanted to make sure that you were alright with everything, it's a lot to take in the fact that your dad's getting married again and that you're going to have a brother or sister" she said simply as the teenager nodded. "I know you're used to it being just you and your dad and I don't want you to feel like I'm intruding on your family but well…" Kate began as Alexis shook her head quickly.

"Kate you've been a part of this family since day one, I love that you're marrying my dad and are going to be my stepmom because you make us happy, so don't worry that I'm secretly devastated over the fact you're going to be living with us forever now" she laughed as Kate smiled slowly, allowing the teenager to slowly wrap her arms around her neck and hug her as they sat there in silence for a moment.

"I better go and check on your father, don't want him rushing ahead to plan our wedding without him" she laughed before Alexis nodded and moved away from her allowing the woman to stand quickly, her hand resting on her stomach slowly. "What do you want? A brother or a sister?" Kate asked as she slowly walked towards the door and looked at the girl who was sat thinking.

"I don't know, I think dad would like a boy because he's already had a girl but I don't know I'm happy with either a brother or a sister" Alexis explained as Kate nodded and quickly left the room to see Rick standing in the corridor holding her clothes.

"If you were nosing into conversation Richard Castle I will never forgive you" she whispered as she walked over and took the clothes from him before placing them on the floor and wrapping her arms around his neck.

"But you're so much in love with me that you can forgive me this once" he laughed before she nodded and kissed him, his arms tightening around her back. "My beautiful fiancée" he mumbled onto her lips as she giggled lightly.

"I love you Rick" she mumbled as he smiled at her and touched her cheek.

"I love you too Kate" he declared before dropping to his knees and pressing his lips against her stomach, a smile covering her face as she laughed at him. "And I love you too little one" he whispered onto her bump as she continued to look at him, her eyes rolling quickly at him before he laughed and kissed her once he was up off his knees. "Future Mrs Castle".

"Katherine Castle" she laughed. "Still deciding on that one".
