Ryan and Espo came back to the precinct right before Kate left for the night. The shock was still evident on both of their faces. She knew that they were full of questions. So, she told them, "Go ahead. Ask away."

Ryan looked at her, "How long have you known that you were pregnant?"

"For about a month."

Espo was shocked, "A month? You've known that you were pregnant for a month and you didn't say anything?"

"We didn't want to let everyone know. It was killing Castle."

Ryan laughed, "I bet. He's not one for keeping secrets. But twins! When did you find that out?"

"Yesterday at my doctor's appointment."

The guys looked at each other and high-fived one another. Despite their bravado, Kate couldn't help but smile. Espo said, "We are going to have two new members of the team soon!"

"Okay, first of all, they are going to be very tiny babies for a long time. So, we want to try and keep them innocent for awhile."

She might as well have been talking to the moon. Because the guys were off and talking about what they were going to teach their newest additions to the team. She smiled, shook her head and put her hand on her stomach. If nothing, these babies were going to have lots of protective Uncles around them. No one would dare hurt them or else there would be hell to pay.

Kate wondered where Castle had wandered off to, but she got into her car and drove home with a smile on her face. Their babies were definitely going to be loved.

When she got home the first thing she noticed was a rocking chair sitting in the living room. She called out to Castle, "Where are you?"

She didn't hear him answer and went looking for him. She finally found him in their bedroom. He was sleeping in their bed. She smiled and climbed in beside him. Kissing his lips softly, he finally opened his eyes, "Sorry, I guess I fell asleep."

Castle had been trying so hard for her. Hard to make sure that she was okay, that he had neglected himself. It wasn't a surprise that he was exhausted. She kissed him again and smiled, "I saw the rocking chair. What have you been up to today?"

"I went shopping. B-bought some things for you."

"Like what?"

"Stuff for you to eat. Protein shakes. All the books say that they will help you to not lose weight even if you can't keep anything down." Then he reached over to his night stand and handed her a bottle of lotion.

"What's this for?"

"To help avoid stretch marks. I figure that it can be a nightly ritual. I'll spread it on your stomach each night before bed. I also bought some epsom salts for your bath."

"You've been busy."

Castle smiled and told her, "I just want the best for you and the babies. I will do whatever it takes to make that you have everything you need."

Kate smiled at him and whispered, "You are a wonderful, wonderful man. How did I get so lucky?"

He simply kissed her and pulled her down into the bed. He kissed her and asked, "How are you feeling?"

"I'm doing much better. I only got sick twice today."

"That's an improvement. Are you hungry? I can make us dinner."

She smiled as she snuggled closer to him. She was happy here in his arms and didn't want to move anytime soon. She put her arm around his neck and pulled his lips closer to hers for a kiss. She pulled away from the kiss slowly and whispered,"I love you Richard Castle."

"And I love you Kate Beckett. Marry me?"

Castle wasn't sure who was more surprised by his sudden proposal. Him or Kate. She was quiet for a few long moments and then she turned to look at him. She didn't say anything. She just studied him.

Long ago, she's told him that she was a one and done type of girl. Never imagining that he would be her one and done. She tried to imagine what her life would be like without him in it and the thought of life without him filled her with sadness. Sure, he was frustrating at times, but he was also the most incredibly sweet man she'd had ever been with. She couldn't and didn't want to know what her life would be like without him in it.

She looked at the man she loved and he seemed to withdraw as he got out of the bed, "I'm sorry. Forget I asked."

She realized then that maybe she had been thinking for far too long. Maybe her silence had been mistaken for something else. She pulled him back down onto the bed, turned his face to hers and looked him in the eyes, "Don't you want to marry me?"

Castle nodded slowly, "I do. I can't imagine a life without you in it. I want to make a home for you and our babies. You once told me that you were a one and done type of girl. Well, I want to be your one and done. I want to be the man that makes you smile and is there to dry your tears. I want to be the man you come home to every night and the man that you kiss goodbye before you leave in the morning. I want to be your everything."

She smiled and then whispered, "Yes."

"W-what?"

Kate laughed and then leaned forward to kiss him softly. Then she pulled back a bit and whispered against his lips ever so softly, "I want to marry you. I want you to be my one and done."

Castle was in shock. After everything he'd done and all of the twists and turns, he'd finally found the woman that he wanted to spend the rest of his life with. She loved him for him and not for his money or his fame. When he finally processed what she said, he smiled and then hopped around on the bed. Acting like a little kid who's best dream had come true. He looked at her with tears in his eyes and whispered, "I love you. So much. You've made me the happiest man in the world."

Kate looked at him and knew what he said was the honest truth. He loved her and he had loved her for the longest time. If she was honest with herself, she had loved him for nearly as long. It had just taken her a lot longer to admit those feelings to herself and to him. But when she had, they had opened her world to the love of Rick Castle. And what a world that was.

Now, she was expecting his babies and their future together was destined to be great. She kissed him and whispered, "Come to bed Castle. I love you and want to show you just how much."

Castle smiled and did as he was told. They made love until early the next morning. Falling asleep in each others arms. Each with a huge smile on their face.

They woke late the next morning and heard Martha and Alexis moving around in the kitchen. Castle laughed and said, "She sure is here a lot for someone who didn't want me to smother her."

Kate laughed and kissed his chest before she got up to get ready for the day. Castle followed her to get ready for their day. She realized that she hadn't been this happy in a long, long time and it felt wonderful...
