Castle sit alone in his office looking at a laptop. He tried to write the words, but nothing coming to him. He keeps thinking about detective Kate Beckett; ever since Tom Demming was on there floor helping them with a case. She had been acting the same way since they first meet each other.

"I can't do this anymore." He whispers to himself. "Maybe it's time for me to go, I'll wear out my welcome." He turned off the labtop, he goes into his bedroom. He looks out his window at the city. "Maybe it's time for a changed in censor too."

The phone rings, he picked it's up and answers it "Castle!"

"Rick, it's Gina I was wondering if you were closed to been done with the second heat book?"

"I been having trouble writing lately. I been thinking maybe I should get out of the city for a while." Castle had been doing some thinking for quite a few days. " I need a break from the 12th precinct and shadowing the detective. "

Gina don't answer him for a while, then she said. "Fine then I don't care if that what it took. Just get that book done."

Castle spoke in anger, "Oh, don't worry it will be done. Good bye, Gina." Slamming his phone down. Castle should feel bad at getting angry at Gina, but he doesn't he feels light.

The next morning

Castle gets himself some coffee and a bear claw. He walks in the 12th precinct of homicide. He see the detective and robbery detective together at her desk talking, laughing and kissing. Kate looks at him; with a smirk. Castle looks like he doesn't care. Kate saw he had a coffee and a bear claw in each of his hand. She thought he had getting her coffee and a bear claw.

Castle walks passed her desk to the captain office. What he don't notice was Kate, Ryan and Esposito were confused just as well.

Captain Montgomery was surprised when Rick, sit in his office. "Sorry, Roy I was wondering if we could talk."

" Sure, what on your mind. " Roy sit down and waited to what Rick had to say. Unfortunately what he was going to say would shock him.

"I'm leaving the precinct, I will no longer be shadowing Kate Beckett." Castle finally told him.

"Rick, are you sure about this? Is there anyway I can changed your mind." Roy couldn't believe it, Rick was leaving and nothing was going to change his mind.

"I'm afraid this has been coming for a long time." Rick stood up and holdout his hand to Roy, he shake it. "I'll let you know when I'm back in town again. He was walking through the door open it walked out.

Kate was getting angry, Castle don't bring her coffee or a bear claw. She saw Castle was heading for the elevator. She stood up from her desk, her angry was so bad; she yelled very loudly. "Damn it, Castle you were supposed bring us coffee and you can't do anything right. Expected you to be a useless mother fucker, can't you ever do anything right. Your poor excuse for a partner." Kate was breathing harshly.

Kate don't noticed the bullpen was looking at her in shocked; but she was in for a surprised, then everyone was shocked in what Castles next words to her where.

"You know what detective, why don't you ask your boyfriend to get your own damn coffee or better yet have someone else get it for you." Castle was on a roll he wasn't going to stop for nothing. " Why, should I always have to bring you and him coffee for anyway. Don't worry you and everyone else don't have to worry about me anymore. " He walked to the elevator and heard Beckett voice.

"What is that supposed to mean?" She was trying to understand ,what he was saying.

"Oh, come now your a detective. Figure it out." He yelled back at her. When the elevator open up, he got in leaving behind a shocked homicide floor. When the doors closed he felt light again. He thought he should felt sad or heartbreaking, but he wasn't any of this things.

Castle got to his loft, he had everything pack up and ready to go. He left his mother a letter. His daughter was away at a college program. He packed everything in the car, started it and drive away from the city. He wasn't going anywhere were he could be find, he don't took his cellphone only a burn cellphone.

Back at the precinct

Kate don't know what had happened. But she knew what she did was wrong, she had to find out; what was going on.

Roy came out of his office not in a good mood. "Beckett get your team together there a suspect to arrest." He slammed the door shut.

Kate decide she would go over to Castle loft find out, what was going on. "Tom, do you mind, coming with us to arrest the suspect."

" Sure, I love to come with you. " Tom had a big smile on his face.

Kate wanted to finished up with the suspect, after that she would go to Castle loft. See if she could talk to him; see that maybe they could go back to the way things were.

Martha enter the loft after six -thirty, nothing looked out of place. Then she noticed a letter was on the table, she open it began to read. Her hand cover her mouth to stop the sob coming out of her mouth. What she was reading break her heart.

Kate had finished interrogation the suspect left for Castle loft. She knocked on the door, expecting Castle to open the door. But it was Martha with red eyes like, she been crying all day.

"Martha, what's wrong?" Kate asked concern. "Is it Rick? Is he in trouble or hurt?"

"Detective Beckett, I'm going to asked, you. But I wanna answer from you. What did you do to my son?" Martha asked with a cold voice .

"What do you mean, Martha?!" Kate was confused , she don't understand why she was so upset.

"You know what I'm talking about you cold emotionless bitch." Martha yelled at her.

"Please tell me What going on I don't understand ,What's going on here."

"You broke my son heart and he left because of you." She slammed the door in her shocked face.
