Kate Beckett has always been a woman with her walls up. Ever since her mother got murdered, she has had her walls guarded up. Kate had joined the police force to try and catch her mother's killer. Kate was sitting in her chair, that's were she was looking at some documents that contained people's names that worked her mother's case.

" Hey Beckett, I have some new information on our murder victim Lilly Hill" Ryan said.

Kate looked up from her desk, she looked to Ryan and nodded. Ryan saw Kate's off look, he knew Kate was looking into her mother's murder. He also knew that, she was running herself ragged trying to find the person responsible for killing her mother.

" Kate are you okay" Ryan asked.

" I'm fine" Kate replied. She got off her chair, and went over to the murder board where she wrote down the information Ryan had given to her. She had been working on this case but, every time she got some new information it seemed to take her around in circles. It also kept her busy so, she would not have to think about the feelings she has been feeling towards her partner Castle.

Lately Kate has been having these feelings for Castle, she doesn't know what they mean. Because, these feeling were unfamiliar to Kate. Sure she went on Dates before and flirty with them. But, she had never felt the feelings she has been feeling towards them as she is feeling towards Castle. Kate went back to her desk, where she was looking back down at the documents that lie in front of her. She was caught up in her own thought until she heard a familiar voice.

" Hey Beckett, how are you?" Castle asked.

Kate looked up to him and smiled, she knew he was her soul mate. Question was, did he feel the same way?

" I'm good thank you" Kate replied, with a smile.

Castle gave her one of his charming smiles, he always knew how to make Kate smile even on her bad days. Castle loved Kate since the moment he first laid eyes on her. He didn't know if Kate felt the same way he did. But, he could only hope.

Castle looked down at the documents that lay on Kate's desk, Castle knew she was determined to catch her mother's killer. He also knew of the warning the man on the phone gave him. The same man who said that, if Kate would continue to pursue this then she would end up dead. Castle couldn't let that happen to the woman he loves, he would have to something to change her mind about pursuing to finding her mother's killer. Even, if she ended up hating him for it.

" Kate, are you sure you want to do this?" Castle asked.

Kate looked to Castle and spoke up.

" Castle I have never been so sure in my life" Kate replied.

Castle looked at Kate, he saw the determination in her eyes. Which made this all the more harder for him to do.

Before he could say anything else Kate got up off her chair, she was talking to Ryan and Esposito about the murder case they were working on. Castle knew he had to do something to make Kate stop investigating her mother's murder. Before it was too late.

He could not lose Kate, he loved her too much to lose her.
