A/N: Ok so I would just like to warn anyone that reads this story that I am in no way a writer. I've never written a fanfiction. I like to write but only when I do papers for school. I love reading fanfiction, and wanted to write some of my own but I don't really have much confidence in myself that it would be good. Basically I'm saying that this could either turn out really bad or somewhat decent… ok so here we go

Disclaimer: I don't own Castle. I'm pretty satisfied with AWM's job so far

Setting: Not sure… But somewhere in season 5 with Caskett together 3 (this does not follow the upcoming storyline for the show.)

Chapter 1

Castle was in the break room making one last cup of coffee for the day, looking through the window at his girlfriend sitting at her desk. Should he tell her? Does she know? No. Castle. She hasn't brought it up. Just hand her the coffee and go home. He finished the cup of steaming coffee and headed towards her, skimming around the corner of the desk. Not meeting her eyes as he hands her the cup of coffee, careful to make sure she wouldn't touch his hand in the process.

"I'm headed home, night Beckett", he says curtly, still avoiding her now questioning gaze, he reaches for his jacket on the chair next to her desk.

As he starts walking to the elevator, Kate tightly grabs his arm preventing him from going any further.

She looks around before she speaks to make sure nobody is in hearing distance, before looking back up at him, "I thought we were going to leave together?"

He finally turns his head to look at her. "Things changed; I think it's better if we leave separately". He turns to leave once more and Kate's hand slides from his arm. She looks after him stunned, hurt in her eyes.

He feels bad for doing that, he usually wouldn't, but he just has to get out of there. Ryan and Esposito come around the corner just as he is walking away from her desk.

"Yo where you goin bro?" Espo says looking at his watch.

Castle just keeps walking without looking up, determined to get out of the precinct without questions.

Ryan and Espo look at him curiously, and walk over to Beckett. "Beckett, did you see that?"

Kate looks back towards the elevator as Castle gets on. She gives him a questioning look through the bullpen, but he turns his head away from her. "Yeah... I saw it. I don't know what's gotten into him, he was fine this afternoon".

"Maybe you should talk to him"

"Me? Why me?"

"Well Beckett I mean you are partners". Ryan looks at her through tight eyes. "Well you know just think about it. Were headed home, see you on Monday!"

"See ya". Replied Beckett focused on her paperwork.

Kate looks at her watch. They had closed the case earlier and were granted to go home by Gates. She was at her desk doing the rest of the paperwork. Just one more signature and done. She filed the papers and grabbed her jacket and bag from her chair. As she was walking to the elevator she pulled out her phone, finger hovering over Castle's name. She decided to take a chance and call, having it go straight to voicemail.

"Hey Rick. Uhh... ah... I was hoping to be with you tonight. I don't know what's up but if you come over we can talk. Maybe have that marathon you were talking about the other day. Umm well think about it. Bye." She pulled the phone away from her ear and pressed end. She didn't know what was up with him recently but hopefully he would come by her place and she could make it up to him. She stepped off the elevator, walking outside and hopping in her crown vic.

Turning the key in the lock she stepped inside her apartment, tossing her keys in the bowl. She was halfway to her bedroom when there was a knock at her door. Ah I guess Castle decided to take me up on my offer. She smiled to herself while she quickly ran her fingers through her hair and checked her breath.

Turning the knob she said, "I knew you couldn't resist the marath..." She stopped dead in her sentence as she opened the door and saw who was standing in front of her. And it was definitely not Castle...

To be continued…?

A/N: Ok so that's it for now... If anyone actually reads this then they should tell me if they want me to continue with this. I sort of have this idea of where this is going but I'm not totally sure. I appreciate reviews and suggestions on what I could improve on or what you would hope to see. But if this is bad then tell me. Haha because if so I'll just let the more experienced writers write stories.
