Hey guys! This in my first and new story. It is kinda AU, but who cares. So in this story, Kate has a sister, Kim. Kim is a NYPD cop too. Well, she is 3 years younger than Kate and she has been kidnapped, by Hal Lockwood on the day Kate was shot. Okay, so in this story, Kim is dating Ryan. Jenny doesn't exist. So all those Jenny scenes? Make them Kim scenes, for this story only! Oh, and um, Castle does not write books about Kim, unlike Kate. I know, sad. Well, this takes place around after Rise and before Heroes and Villains. Somewhere in between. Does not follow the storyline.

So, enjoy this story! Read on!

Disclaimer: I own nothing Castle… Does posters, books and CDs count?

Chapter 1

Kate looked through everything again. She went through the reports a hundred times and she still got nothing. She can't believe Kim was gone. Kidnapped. She remembered the last time seeing her little sister, smiling sadly at her while she gave her eulogy at Captain Montgomery's funeral. She remembered the look on Kim's face when she was shot. Kim screamed for her. Then, in a swift movement, she was gone.

She looked through the reports again, this time making sure nothing seemed fishy. She got up and started packing. She arranged all the papers neatly in a stack before placing them in the box. She left the box on her desk and turned around to look for Castle. He was in the break room making coffee. She can't see the glint in his eyes. The glint of happiness. But he put on a fake smile for Kate. He came out of the break room and handed Kate her coffee, "Anything?" he asked, and hoping there was something she had found.

"Thanks. No. Not yet, anyway." She smiled at him. She took a sip from her coffee. "Hey, after this cup, I'm heading home. You should head home too. Get some rest."

He looked at her, his look saying no. He wanted to find something first, a lead. He wanted to find his best friend and he is not going to sleep peacefully until they find her. He would bring Kim Slushies' every Thursday and Saturday. It was in their timetable. Every Thursday and Saturday she would be expecting him to bring her a large Slushie. The rest of the days, Ryan would buy her favourite from Starbucks. Castle always knew her favourite, just in case. It was Double Chocolate large, extra whip cream, chocolate chips and ice.

"Kim would want you to. Go home, rest. We'll come back tomorrow and continue. I promise." Kate told him, grabbing her coat and putting it on. She was done with her coffee. Castle gulped his down, wincing as the hot liquid went down his throat. He put his coat on and shuffled towards the elevator. Kate held the door for him, and smiled when he entered.

Kate got home, frustrated. The cab driver gave her the wrong change and when she told him, he insisted that it was the right amount of change. She placed the keys on the coffee table, and headed for her bedroom. As she walked to her bedroom, she walked past Kim's bedroom. Kim stayed with her, she had refused to move in with Ryan until they were married. Kate sighed and went it. The room was in a mess. Kim had said that it was no point cleaning the room if she knew where everything was. Kate decided to clean the room up. She stood there for a while, taking everything in. She left the room a while later to go clean herself up. She took a bath, then changed into her pyjamas, and went back to Kim's room. She started cleaning the. She tossed all the dirty clothes to the laundry basket and started picking up things that belonged to Kim on the floor. Books, CDs, her headphones, her headbands, stationaries and…. A pregnancy test stick?

She looked closer at the stick. It said "pregnant". Her eyes widened. Surely Kim could not be pregnant. She is not even married! But this test, it should be hers. Who would throw a pregnancy test stick into Kim's room? Does Ryan know? How far along is she now? It's been 4 months since she was kidnapped, maybe she is showing now. She dropped everything except the pregnancy test and ran to her phone. Where had she placed them? She ran to the kitchen and checked the island. Not there. She ran to her bedroom and checked her dressing table. Not there. She checked her bed. Not there. She sighed, where is it? Her coat! She checked her coat. She had flung it onto her bed when she came home. It was there. She let out a relieved sigh.

She did the unlock pattern, her fingers flying across the screen. She went to her keypad and typed Ryan's number. On the third ring, he answered, "Hey Beckett. Do we have a body?" he asked.

"Ryan." She breathed. "Is Kim pregnant?"

"W-What? Um, what are you talking about? You found her?"

"No, we didn't find her. I found a pregnancy test in her room and it was positive. She's pregnant!" She exclaimed. She ran her fingers through her hair.

"She is? And she didn't tell me. Maybe, she didn't want-''

"No! Ryan, she obviously wants to have kids with you. Maybe she was not ready. But she would've talked to you about it. She wouldn't have just gone and aborted it. Trust me. She's not that type of person." She said, grabbing a headband and tying her hair up.

"Okay. But I can't believe she's pregnant!"

"Yea. Hey Ryan, I'll talk to you tomorrow, okay? Call me if there's a drop." She said, rolling her eyes when Ryan got excited.

"Yea, okay. Bye."

She hummed and ended the call. She still can't believe it. She's going to be an aunt! She got back to her senses and rolled her eyes at her own childishness.

But, wait. Kim was kidnapped by Hal. He might have done something to the baby. He might've killed it. He might've killed Kim too. Kate sighed. Hopefully Hal didn't do anything and kept both of them alive. Kate just wanted Kim –and now, her little niece or nephew- back alive.

Kate got back to cleaning Kim's room, smiling whenever something of Kim's reminded her of their childhood. She can't bear to lose her sister. She had lost her mother, but she can't lose her sister.

Kate decided to call it a night after ordering Chinese takeout and watching a random movie on HBO.

So guys, how was it? Enjoyed it? Please review! I know this chapter is kinda short. Longer chapters are promised! So, if you're wondering, Castle did say "I love you" to Kate when she got shot. Don't worry; we'll have some Caskett soon! And some Rykett (Kim and Ryan, since her last name is Beckett) too!
