Chapter 1

Castle came home and shut the door firmly behind him, then went straight to his study and sat on the chair with his hands formed in fists now. Very angry very frustrated of what he just saw. Without thinking, he pulled the phone from his jacket's pocket and dialed 'Kate.

It was Kate's day off. It was almost 8pm and she was sitting on her couch; watching TV, when she felt her phone vibrating. It was Castle. A smile formed on her face. "Yes, Castle!" she responded in a very normal voice which made him angrier than before. He didn't respond because his mind was else where now. All he could think of was her in the other guy's arms. How could she do that to him?

"Hello!" Beckett said when she got no answer, and that brought Castle back to reality.

"Are you seeing someone?" His voice was full of anger and hurt.

"Excuse me!" she was so confused now, all she could think of was, "Is he trying to ask me out?'

"Are... You... seeing some one?" he repeated himself, "you know, like dating someone!" now his voice tone was higher. Kate noticed that this wasn't him asking her out. This was much more than that, because he seemed either drunk, or he was really… really mad at her.

"Why do you ask? Castle, do you have a blind date for me?" she said it with a teasing tone.

"I'm not joking here. Answer my question Kate".

'What the hell is going on' she thought. "Castle, are you drunk?"

"I wish I was then I would have forgotten what I saw by tomorrow morning" eyes full of tears, a betrayal tears. How could she do that to him, after telling him she has to take down that wall she had built inside and basically telling him to wait for her? He was so faithful since then. He didn't have any kind of relationships with women.

Kate felt by his tone that this was a serious matter. "What is it that you saw that made u call me and yell at me?" she was angry as well now, because she had no idea what was going on.

"You know what, I shouldn't have called. Have a nice evening, Detective!" with that he ended the call, without even letting her answer him.

He turned off his phone and just sat there, eyes shut, thinking.

On the other side of the phone, Kate was shocked by his behavior. "Detective"! Since when he calls her that, besides, he never ends the call. It's always her who ends the call, and most importantly he never gets mad at her. "Wait"! She had a flash back for the summer: he was mad at her when she disappeared after the shooting and didn't call him. He stayed mad at her until she told him she broke up with Josh.

She started to build a theory: "what the hell is going on!" she said, whispering to herself.

Now, they both were thinking about each other. Rick was frustrated by what he saw earlier while Kate was so angry for not knowing why Castle acted like that. She picked up her phone to call him but then she put it back on the table. knowing Castle after all these years, He never gets angry and when he does it has to be really a big deal. So, instead she sat there with her thoughts.

Meanwhile the loft's door opened. Rick heard the noise and went to see if it was Alexis coming back from the morgue, she was busy with Laine a lot these days, but, instead he found his mother.

"Oh ... mother, it's you" he turned back to his study.

"I know u don't like me staying here, but really Richard darling! Is this a way to say hello? I didn't teach u to be rude son!"

He turned to face her, "Sorry, I'm just in a bad mood, I'll go get some rest, When Alexis comes home let me know, I haven't seen her today".

Who was he kidding here? This was Martha. She read his face right away.

"Is there something wrong? Did you have a fight with Beckett?" she knew it had to be that because he never gets that serious unless it's about Kate.

Ignoring his mother, Castle went to his bedroom and threw himself on the bed with a long Sigh.

Martha went after him, "Richard, are you okay?"

"I will be, when u let me get some rest mother." he responded with his face buried in the pillow.

Yeah, well, that was not going to happen. "You can talk to me, you know. " she was now standing closer to his bed.

"Will you, pleaaase, leave me alone so I can get some sleep" His headache was getting really painful now.

"When are you going to put an end to this? You have to live your life. Ask her out. If she doesn't want to, then you should move on ..." she went on and on, and Castle, knowing that she won't leave him alone until he tells her what was wrong, stood up, went to his study, grabbed his phone and went out of the loft, leaving Martha standing in his bedroom.

He took a cab, gave the driver an address and stared through the window, thinking. And before he could find an explanation to the events of this day, the driver told him, "sir, we are here."

Looking confused of where he was, he gave the driver money and went out of the car. Castle found himself facing Kate's building. He must have given the driver her address, without realizing.

Castle went upstairs and when he reached her apartment, he froze facing the door. 'What am I doing here?' After 15min, He was still there, sitting beside the door; in the cold.

Carried away with his thoughts when a sudden noise brought him back to reality. He looked up and saw Kate looking at him confused.
