Family. It's everything right? Staring down at her lounge room-staring down at her family, a place in her heart warmed. This same spot was cold for most of the time that she was at work. They death and destruction pulled her down for most of the day until she came home and saw her family once again.

Her family was now her life. After so much disappointment and heartbreak in trying to start and grow her family, it was humbling to have her tiny, little creatures running around the house.

The smiles on their faces lit up every sad thing in Kate's day. If it had been a hard case she would come home and her children and amazing husband would cheer her up until she couldn't help but smile. Rick was still a kid though. He hadn't grown up at all in five years. You'd think that having three children would drain a man's energy not give him more.

Patrick Alexander Castle was the eldest adding up to be just over four years old and Quinn Houghton Beckett was about to turn two in a few weeks. Kate had lost three babies already to miscarriage, two before Patrick was born and one only three months ago while trying to add a fifth member to the family. That's why they hadn't told the kids about her being pregnant yet. They didn't quite understand what Rick and Kate meant when they told them that their mummy was no longer having a baby. It tore her heart seeing their confused and sad little faces. They would wait a few months and if the baby was still around then they would tell them. She just hoped that if it did happen again it wouldn't happen like it did the first time.

*Flashback to the 17th of June 2015*

"Stop police!" she screamed as she chased the suspect down the narrow, wet alleyway. "NYPD I said stop!" Kate could hear the heavy footsteps of Espo and Ryan chasing to keep up with her after she caught the early sent of the guy they'd been looking for. She had given Castle strict instructions to stay in the car but she could hear his loud and heavy panting trailing behind as his fitness levels were greatly tested.

"Stop police!" she yelled again as the perp neared a dead end. She'd got him right where she wanted him. But things couldn't always go right for her and in the instant that they Suspect turned around when he realised his immanent fate, Kate felt a huge burst of pain rush through her stomach. She toppled to the ground and felt a warm sensation run down her thighs. Ryan and Espo ran past her and gathered up the suspect while Rick finally caught up and Collapsed beside Kate.

"Kate? Kate!" he exclaimed, panic ripping through his voice. "Kate you're bleeding!" She looked up to him and saw pure horror in his eyes. She knew exactly what was going on but by the looks of him, he had no idea.

She gave him a look of sadness and apology.

"The baby?" he murmured softly as a tear ran down his cheek.

"I'm so sorry Castle," she whispered softly. That's all that she could make out as the pain was still an uncomfortable constant in the lower part of her torso.

She didn't remember much of what happened next. Small memories of Rick calling the ambulance and Kevin and Javier having to force themselves away from their grieving friends to take the perp back to the precinct was all she had left. The next thing she remembered was waking up pin the hospital and being told by a doctor that she had lost her baby.

*Back to present*

They had almost given up after that day. They were certain that having children was impossible for them when the second miscarriage occurred but had a glimpse of hope when they had successfully gotten Patrick into the second trimester and the doctor said that he'd most likely last until the very end. They weren't that lucky though. Patrick was born dangerously early and almost didn't make it. It was like they couldn't catch a break. Luckily Kate's pregnancy with Quinn was a breeze and there were absolutely no complications what so ever. Rick and Kate just prayed that they would be that lucky with the little he or she that Kate was carrying right now.

Tonight was special though. Alexis and Blake were there too. It was a treat when they had visits from them. Alexis had two little girls but both of them didn't have the same father. Paige Katherine Harrison-Castle who was four years old and Pi's daughter, and Astrid Martha Donalds-Castle who was four months old and Blake's daughter. It had been a rough relationship with Pi and Alexis and once Paige was born they spilt up pretty quickly. He still fully supported her though and they remained friends. Blake and Alexis had fallen madly in love when Paige was almost nine months old. They had gotten engaged three months before she fell pregnant with Astrid.

It was a huge family get together and after the year that they had all had; this is what they needed. Family was the one constant in her life now. There were no more lonely holidays where she would sit alone in her apartment, eat takeout and wallow in self-pity. Even her father had remarried and moved to the Texas where his wife Mary had grown up. He was tremendously happy and Kate couldn't have asked for a better step mother. They'd all be coming to the loft for Christmas which was next week. People would be flying in from all around the country to join them.
