A/N I want to thank Sensaiman for betaing this for me. I definitely appreciate it! I hope you enjoy the latest chapter. Thanks in advance for reading and I love any and all reviews.

Everything changed when Lillian went to her six months doctor's visit. Kate had noticed that sometimes Lillian wouldn't hear her when she came into the room if she came up from behind her. If she was close to her, she could hear her, but if they were any further than three feet away from her, she wouldn't hear them.

After a series of tests, the doctors determined that Lillian had severe hearing loss. She had lost about eighty percent of her hearing and what she had left, was marginal at best. She could hear Kate better than Castle. It broke their hearts to think that their daughter would never be able to hear them.

The doctor did give him some good news. With surgery and hearing aids, her hearing could be almost normal. She had surgery when she was barely seven months old. She had been fitted for hearing aides soon afterwards. Kate and Castle could tell that she could hear them. Because her face broke into the biggest smile when she heard her parents voice clearly and from behind her. Which, she had never done before.

She would need regular checkups, but with hearing aides, her hearing would be normal. The doctor didn't see any reason for her to not develop like a normal infant.

Eight Years Later

Josh Davidson sat outside the White Plains home watching and waiting for a view of his daughter, the daughter that he had given up all rights to nearly eight years ago. He wasn't sure why he was here. Other than he felt the need to make things right with Kate; and maybe for a chance to see his daughter. He'd heard through the grapevine that Kate had given birth to a baby girl. At the time he hadn't cared. It hadn't mattered to him because he hadn't wanted children. At least he thought that he didn't, but things change. Especially when you are diagnosed with cancer and given mere months to live.

He watched as the door opened and closed multiple times. Allowing the occupants to come and go as they pleased. He saw five children gathered around Kate. Josh could tell that they were all hers. Well, except maybe for the redheaded little girl. The others were all Kate though. He knew that the oldest of Kate's children was his daughter. So, he got out of his rental car and headed over to where Kate was playing with the kids. Kate obviously hadn't heard him approaching, because when his shadow crossed over her and she looked up, she startled and put her hand over her heart and whispered, "Josh."

He saw the fear and anguish in her eyes. He knew that he had put that there and he would be forever sorry for that. He had changed a lot in the last eight years. He had come here wanting to see his daughter, but looking at the children gathered playing in the yard, he couldn't see one child that looked like his. They all looked like Castle.

He looked at her oldest daughter and then he heard Kate tell him, "She's not yours."

"Castle."

It wasn't a question; it was more of a statement. He watched as the children threw a tennis ball to what was obviously their dog. Kate finally nodded and Josh said, "I'm glad. She deserves to be happy. You deserve to be happy."

"She is. I am."

Before she could say anything else, she heard the door to the house open again and she knew that it was Castle. She heard him ask, "What the hell are you doing here Davidson?"

Josh held up his hands and told them, "I just wanted to see..." He shook his head, "I guess it doesn't matter what I want. Because I know that none of it matters. I won't be back. I'm sorry to bother you."

With that, he turned and hurried back to his car. He'd seen what he had wanted to, but maybe not. He'd been expecting to see his child. A child that he and Kate had made, but was surprised to see that child never existed. He supposed that it was a good thing, because he wasn't a father and never would be. He could admit that Castle was good for Kate. He had always known that Kate had loved Castle, even when they were married, He'd seen the look in her eyes whenever Castle was around. It was a look that she never got when she was with him. He had always known that their relationship was doomed.
He knew that it was for the best. Now, he would die and be at peace.

After Josh drove off, Castle looked at Kate and asked, "What was that all about?"

Kate shook her head, "I have no idea. He says that he wanted to see Lillian..."

"Why? Why after all this time?"

Kate shrugged and told him, "I have no idea. I don't even know how he knows where we live now..."

Castle shrugged and turned to watch their children playing. They had five perfect children and they had another one on the way. Kate had been devastated when she'd gotten the news about her latest pregnancy three months ago. They'd decided that five was definitely enough, but apparently life had other ideas for them. Ideas that meant they had to move out of the loft and buy a house together. It was the best decision he'd ever made.

Kate's commute to work was longer, but she had grown to love this house. On any given day the sound of their children's laughter filled the air. They also adopted a bulldog named Pepper three months ago. That had been Alexis and Lillian's idea. The two girls had been asking for a dog for the longest time. Pepper had shown up at their door one rainy night. Kate had fallen in love with her slowly.

Castle sat down behind his wife and let his hand rest on her stomach. Then he kissed her neck softly and asked, "Any regrets?"

She smiled and turned back to look up at him. She nodded and whispered, "Only one."

"What is that my dear Detective?"

She kissed him softly and whispered against his lips, "The only regret that I have is that we spent so long dancing around us. When I think that we could have missed this..."

She watched at their kids played in the sprinklers and the squeals of laughter resounded in the air. There had been a time when she couldn't imagine being a mother of one child, much less five and in a few months, six. She also knew that she wouldn't trade this life for anything in the world. No amount of money could replace the life that she had built with the man she loved, the man who had loved her even when she was married to someone else. The man that had given her what she needed most. Family. Something that she desperately needed at that time in her life.

Kate felt Castle's hand work it's way under her shirt. He let his thumb trace small circles over her skin. Over the place where their baby was growing and developing. They'd already made four beautiful children together and they were each a precious gift. She'd been upset to find out she was pregnant again. She had cried for hours that day, but she knew that she would love the latest addition to their family.

Looking at Alexis she couldn't help but smile. Their oldest daughter had become a bright, funny and outgoing child. At fourteen, she was just starting to get interested in boys, although, for the most part, boys were on this side of yucky, but Kate had noticed her talking about a certain boy in her Algebra class at school. She had tried to talk to Castle about it, but he had shook his head and told her that he didn't want to hear about it. To him, Alexis was still his little baby.

Alexis loved her siblings. She was the perfect big sister. She was extremely protective of her younger siblings. She had taught Lillian to walk when she was only nine months old. From there, Lillian never slowed down. Despite her hearing loss, she had developed into a happy, healthy little girl. Unless they had known about her hearing loss, no one would guess that she had ever had issues with her hearing.

Of all their children, Lillian was Castle's daddy's girl. She was the one that was always in on his latest schemes. He bought her a laser tag vest when she was barely four. Allowing her to join in with her father and sister. In some ways, she was better than her father or sister. Kate thought that it was because she was smaller and could hide behind the couch and strike out of nowhere. It always made her laugh to watch them play. Castle had tried to get her to join in, but that had always been his thing. Something he had started with Alexis when she was little and Kate didn't want to intrude on that. So, she would sit on the sidelines and watch as her family played.

Kate had risen up the ranks at the precinct. Montgomery had been promoted to Police Commissioner and they needed someone to take over. Kate had been offered the position, but she had turned it down. It would have meant playing politics and that was something she wasn't good at. Plus, it would take her out of the field. Which is what she enjoyed. She wasn't management material. No, she would much rather do the arresting and investigating. Leave the politics to someone else. She was second in command at the twelfth and that was fine with her.

Castle smiled and asked, "What are you thinking about?"

Kate shook her head, "Josh showing up here just got me thinking about us. About everything that's happened over the past eight plus years."

He kissed her slowly and asked, "Would you change anything?"

Looking at her children playing and sitting here with Castle. She knew that she wouldn't change a thing, because every road had led them to this. Who's to say if they would have ended up here if anything had changed? Even the slightest difference could have potentially changed everything for their family. It wasn't a risk that she was willing to take.

She smiled back at him and whispered, "No. I wouldn't change a single thing."

"Me either."

At that point, the sky opened up above them and the rain came down. The kids squealed loudly, but still played in the water. Neither Kate nor Castle had the heart to make them go inside. Then, off in the distance, Kate and Castle saw a double rainbow. She turned around in his arms and kissed him again oblivious to everything and anything else. Safe in his arms, she knew that there was no place she would ever want to be. This was it for her. He was her one and done. She had known it years ago and she knew it now. He was her home. Her safe harbor. Everything she wanted out of this life could be found in his arms and the arms of their children.

Gone was Kate Beckett career driven and hell bent on revenge. In her place was Kate Castle. Wife, mother and best friend to the most amazing man she had ever known. Some would say she had lost herself when she met Castle. She would disagree. The day she met Castle was the day that she had found herself. She had discovered how wonderful life could be through loving him. He made her a better person and she had more fun since he had come into her life. She looked forward to spending the next fifty years with him; raising their children, and surrounding themselves in the love that they had spent building together, nothing would ever make her happier. Nothing...
