A/N - Here's the last chapter of Falling in Love at Remy's. Thank you all for staying with me through this journey. Special thanks to CaskettMyHeart and AngeiiK for helping me through this tough couple of months.

"Rick and I have been fighting, dad." she said, sitting on the too familiar couch of her father's living room. "He is just overprotective. It's been over 6 months, dad, and he still hasn't gotten over it. He is starting to drive me crazy..." she ran a hand through her face and hair.

"Do you love him, Katie?"

She gave the question a thought. She had feelings for him, yes. Since the day Meredith had shown up at his doorstep after she'd rescued Alexis (also the day they shared their first kiss). Not that she was willing to admit that at the time. And all the songs made sense, just like her mother had said they would. That meant love.

"I do, dad. I love him." she whispered more to herself then to him. "But our relationship seems to be hanging by a thread." she spoke a little louder.

"But those are the best kinds of relationships, Katie."

She gave him a questioning look and he quickly explained. "All those couples that seem to share a solid relationship remind me of barriers and sharp edges. Frontiers they are afraid to cross, because it might rupture the dike and flood everything, ruining all they've built. But the threads that hold relationships like yours are made of steel. It bends, it twists, it stretches out, but it does not break."

"Jo and I weren't the couple you always imagined, Katie. We were the happiest couple ever known, but we would fight all the time, because we were different."

"In life," he continued. "You're not supposed to find someone exactly like you, you're supposed to find your opposite."

That reminded her of Rick, talking about the Ying-Yang and harmony one day, when he was bored and had absolutely nothing to do, but try to entertain her. It had been sweet of him...

She had to go back. She had to go to the loft and apologize for snapping at him. She had to make sure he knew how much she loved him. Of course, she had told him multiple times, and even showed him, but she had to make sure that he knew she had meant it.

Traffic in New York City sucked as always and it felt like an eternity for Kate to get to the loft, though it had only been a couple of hours. She rushed through the lobby, eager to get in the elevator and see him, talk to him.

The elevator ride seemed even longer, but soon she was knocking desperately on his door. He swung it open, the stunned look on his face surprising her. "Kate, what are you doing here? I thought you were mad at me..."

She pushed past the door, put her hands at the sides of his face, got on the tip of her toes and kissed him. Just a simple act of love and affection that meant so much to the both of them. "I love you, Rick. I love you so much... I can't lose you, never. Much less to something so stupid."

"What happened, Kate?"

"Our relationship hangs by a thread, Rick." he gave her a confused look and she giggled. "Our relationship is the best kind of relationship, because we have stupid fights, but our love is stronger. We make it through, do you understand?" she blurted out all too quickly.

"Uh... no..."

"Doesn't matter, I'll explain later. Dad made me realize that I can't live without you, Rick. Right now, I just want you."

- 4 years later -

After another long, tiring day at the precinct, Kate just couldn't wait to go home and see her little boy.

Castle had been thrilled when he found out it was a boy. He wouldn't mind having another girl, after all it would be a totally new experience with Kate, but the thought of being able to do all the things his father hadn't done to him made him even happier.

They prepared everything for the baby's arrival, the room was exactly as Kate had dreamed and they both hoped their child would enjoy it and get the most out of it.

Little Aiden arrived on the 27th of July, after 13 painful hours of labor and neither Kate nor Rick could find the words to describe the feeling of holding their newborn child.

She swung the door open and was immediately hit by the smell of Christmas gingerbread. Approaching the kitchen, after dumping her coat, purse and shoes in the closet by the door, she saw her little boy with messy brown hair and green eyes just like hers smiling brightly at her, and was greeted by her husband with a loving kiss.

She helped the boys finish the cookies and gave Aiden a bath. When they were done, she took him with her to pick Alexis up from Paige's house and both kids played in the back seats until they were back home, where she tucked them both in and wished good night.

In the middle of the night, though, when she was putting the surprise Christmas gifts under the tree, she heard her little boy calling for her and met him at the top of the stairs. He'd had a nightmare and was really scared. She tucked him in again and pushing away a few lonely strands of her, she asked if he'd like her to tell him a story.

"Yeah, momma! A story! The story of how you met daddy!"

"That one again?" she joked and he nodded, smiling at her. "Okay, it all started at with a boring day at the precinct..."
