Don't You Fret

"Don't you fret, now, I'll be there

I'll be there to put you right

I'll be there to hold you tightly

When the sun goes down at night"

Beckett woke up to the sound of her phone ringing. She hadn't been feeling good the past couple of days so she really just wanted to sleep. Picking up her phone she saw that it was Castle calling and she smiled.

"Morning," Beckett said when she answered the phone. She loved when they video chatted.

"You look like death came to visit," Castle responded.

"You really know how to woo a woman," Beckett said rolling her eyes.

"I just mean you look a little pale," Castle said.

"My stomach has been bothering me," Beckett said.

"You want me to fly down and make you feel better?" Castle asked.

"Despite what you think, sex does not cure nausea," Beckett said with a laugh.

"You never know until you try!" Castle said laughing back. "A think a long shower might help also. If you bring your phone in there I can make sure you are doing it right."

"I think I know how to take a shower," Beckett said. Her phone then went off again. "Crap. I have to call in to work."

"Take a sick day," Castle said. "You can stay home and I can sing soothing songs to you."

"The Thong Song is not soothing," Beckett said.

"I'll sing it Barry White style!" Castle said. "That is sure to make you feel better."

"I seriously have to call in to work," Beckett responded. "I love you."

"I love you, too," Castle said. Beckett blew Castle a kiss which he grabbed and smeared all over his fast.

After hanging up with him, Beckett called McCord and got ready for work. She looked in the mirror to put her make up on and thought to herself that Castle was right that she looked a little like death had come to visit her. She hoped her stomach bug would go away soon.

When Beckett found that out that her case would take her back to New York City she was super excited. Not only would she be able to see Castle, but she would also be able to work with Esposito and Ryan again. She really missed those guys. She was a little shocked, however, when she walked into the precinct and saw Castle already there. She stifled her laugh when she saw Gates yelling at him. She knew that some things would never change. Castle looked as giddy as a school girl when he saw Beckett walk up.

"Why didn't you tell me you were coming to town?" Castle asked with a giant smile.

"I was going to surprise you," Beckett responded trying to maintain her professionalism in front of McCord.

"Well done," Castle said with a laugh.

The mood changed quickly, though, after McCord and Beckett announced their role in the investigation. Beckett could tell that Esposito, Ryan, and Gates were not pleased to have their case taken over without a given reason.

Castle felt stuck between a rock and a hard place since he respected Beckett's position, but at the same time didn't want the guys mad at him. He didn't realize that something as simple as offering to get McCord and Beckett coffee would not go over well with the guys. He just wanted an excuse to see Beckett. When the guys started pressuring him to get information from Beckett he didn't really know what to do. He wanted to respect Beckett's wishes, but his curiosity about the case was also eating away at him. Plus, he was disappointed that he hadn't really been able to see much of Beckett since the investigation started.

Later that day, Castle sent Beckett a text to meet him in the break room. Beckett hurried as soon as she could to go see him.

"You seem to be feeling a lot better," Castle said when Beckett almost skipped into the room.

"I think I just needed to eat something," Beckett said.

"And see me," Castle said wiggling his eyebrows. He handed her a cup of coffee.

"I have so missed your coffee," Becket said. "And you, of course." She gave him a wink.

"Well, if I knew coffee was a code word for my...," Castle started before Beckett smacked him in the chest. Beckett gave him a huge smile. Castle had missed that gorgeous smile. It wasn't the same looking at it on a phone screen. As Beckett started drinking her coffee Castle asked about getting some details on the case.

"Is this a bribe?" Beckett asked, looking down at her coffee.

"No!" Castle said a little too unconvincing.

"Castle, you are not going to Castle me on this one," Beckett said putting down her coffee. Since McCord started coming Castle tried to get Beckett to tell him based on nods. Unfortunately for him she gave him way too many nods.

"See ya, Castle," Beckett said with a teasing voice as she left the room. The tone of her voice and her strong will to keep the facts hidden turned Castle on a little. The feeling quickly died down when Esposito got on his back for not being able to get details from Beckett.

As Beckett left with McCord she felt bad not being able to discuss the case with Castle. She hated having to hide things from him. He was her partner and she wanted to be able to tell him.

Knowing there was something that he did not know made Castle want to solve the case even more. Being able to go to a dark, seedy warehouse with the guys made him feel better, though. Of course, if it was up to him he would have gone in there with the biggest gun possible, but like Beckett, the guys were not going to let him have a gun. When they discovered the guns in the camera case he felt like he was entering a spy movie. The excitement quickly went away for a moment when he heard someone yell at them to put the guns down. He was happy to turn around and see that it was just Beckett and McCord.

Beckett wasn't that shocked that the guys had discovered the guns. She knew they were good. She was very disheartened later when she found out McCord was shutting down the investigation into the case once the CIA got involved. She hated to think that a murderer could go free. She and the guys always worked so hard to catch the killer. Plus, knowing there was a murderer not captured hit a little too close to home for her.

Beckett decided to take a walk to clear her head. While she liked her new job in DC, she didn't like some aspects of the job. The job felt like there were too many exceptions on how a case could be handled. It seemed more like politics than actually finding the bad guys. As she was walking Beckett started to feel a little nauseous and lightheaded again. She sat down at a bus stop bench to rest. A elderly woman, probably in her late 70's, was already sitting down. She looked Beckett over.

"The first few months are the hardest," she said, breaking Beckett away from her dream land she was in.

"Excuse me?" Beckett said.

"I went through it four times," the woman said. "Every single time I got sick. Is this your first?"

"My first what?" Beckett asked.

"Child," the elderly woman responded.

"What?" Beckett asked shocked.

"The first one is always the hardest because you never really know what to expect," the woman said. "You know my daughter is pregnant with her first child. She looks so radiant..." The woman kept talking but Beckett wasn't listening anymore to what she was saying. A quick panic was rushing over her. She started to think about the last week. She knew she hadn't been feeling good and her period was about 5 days, but she accumulated that all to stress. Stress always made her a little out of whack. Beckett all of a sudden felt the elderly woman's hand on her cheek.

"You are a little flushed, dear," the woman said as she stood up to get on the bus. "That is just your hormones fluctuating. The further you get along in your pregnant the more they will stable out." Beckett just stated at her as she got on the bus. Beckett shook her head. There is no way she could be pregnant. Beckett said as she headed back to the precinct. On the way she sent a text to Castle to meet her.

As Castle walked into the break room he noticed that Beckett seemed a little gloomy. He figured she was a little sad that she would be leaving the next morning. He tried to cheer her up by inviting her to his place, but he understood if she wanted to go somewhere else since coming home to him, his mom, Alexis, and Pi might not be the greatest invitation ever. When she declined his offer, though, he was a little shocked, until she handed him a flash drive. Castle quickly realized that Beckett was a little out of sorts because of the case. Castle made it his goal to help solve this case for Beckett since she was no longer allowed to investigate.

After everything had gone down and Beckett had given the anonymous tip to help with the case, she finally felt she could relax. Part of her knew, though, that she could not fully relax. Ever since she talked to the old lady on the street thoughts about the possibility of her being pregnant were running through her head. She decided that she needed to do something to make the worry go away so she decided to buy a pregnancy test. Buying the test at the drug store made her feel like she was buying cocaine because she was convinced everyone at the place was staring at her. When she went to go take the test, though, she chickened out. She decided she needed to speak to Castle first.

When she got to his apartment she went to tell him, but instead spit out that she was the anonymous source. As Castle started talking about how great she was for what she did, all she could think about was how she was going to tell Castle that she might be pregnant. They had never really discussed having children before. She wasn't sure how he would react. She didn't know if he would want another child considering he now had a child who was an adult. She also worried that if she told him and he was super excited and then they found out she wasn't pregnant that he might want to start trying to have kids. She didn't think she was ready for that. That made her panic a little realizing that she didn't think she was ready, but if she was already pregnant there was nothing she could do about it.

After a few moments of silence, Castle gave Beckett a few light pats on her arm and sat up. When Castle stated they needed to talk Beckett didn't know what to think. When his tone got serious she started to worry. She was worried he was about to give her an ultimatum about her job, or even worse, break up with her. When Castle stated their situation wasn't working she started to feel like her world was going to crumble. Until she saw the key. The key represented to her that no matter how difficult the road ahead would be, Castle would be there by her side.

After Beckett gave Castle a huge hug and kiss she knew she needed to tell him.

"Castle, I am so happy you are moving to DC. I need to tell you something also," Beckett said with Castle's arms still wrapped around her. Just as she went to speak Castle's door bell rang. He told her to hold her thoughts. He needed to go shoo away the person who was ruining his long needed alone time with Beckett.

When Beckett found out that she was fired, it was like the cherry on top of the emotional roller coaster she had been riding on all day. McCord quickly left after breaking the news. After Castle finishing escorting McCord out and locking the door he turned around to find Beckett no longer in the living room.

"Beckett?" Castle called out. He made his way into their bedroom where he saw a light coming from the bathroom. He peeked in and saw her crouched down next to the toilet. He bent down next to her and pulled her hair back. "I'm sorry. They're stupid. They don't realize what they're giving up." Beckett leaned over and rested her body against his, her head laying down on his shoulder. Castle gently rubbed her back. They sat there for a few minutes in silence.

"You okay?" Castle finally asked.

"I think I'm pregnant," Beckett blurted out. Castle stopped rubbing her back, frozen in shock. That was not what he had been expecting. Beckett sat up and looked him in the eyes.

"Have you taken a test?" Castle asked. Beckett shook her head no.

"I'm sorry, Castle," Beckett said.

"About what?" Castle asked.

"I know we didn't discuss having kids," Beckett said.

"First of all," Castle started, "there is nothing for you to be sorry about. A woman can't make a baby by herself. Second, I love you, Kate. Having a baby with you would be wonderful. The timing may not be the best, but some of the best things are surprises. The question is are you okay with this?"

Beckett sighed. "I do want kids," Beckett responded. "I just always thought it would be more thought out."

"Our relationship has always been kind of spur of the moment so why would a pregnancy be any different?" Castle said with a laugh. Beckett gave a slight smile. "You want me to go to the drug store and get a test?"

"I already got one," Beckett said.

"Where is it?" Castle asked.

"In my purse," Beckett said. Castle got up to go get the test. He came back in and handed it to her.

"Want me to hold you hand?" Castle said with a smirk.

"Get out," Beckett said with a nervous laugh. Castle left the bathroom, closing the door behind him. He sat down on the edge of his bed. He couldn't believe he might be a father again. Beckett came out of the bathroom and sat down next to him. Castle wrapped his arm around her, pulling her into him.

"The waiting is the hardest part," Castle said. They sat there in silence, watching the minutes slowly go by.

"Times up," Castle said suddenly.

"You go look," Beckett said.

"We do it together," Castle said, pulling Beckett up as he stood up.

"I think I am going to throw up," Beckett said.

"Well, if you are pregnant, get used to that," Castle said. As they entered the bathroom Beckett motioned for Castle to look. Castle picked up the pregnancy test and smiled.

"Wow. Pregnant and fired in one day," Castle said. "Someone is going to need to update their Facebook." Beckett reached out and took the pregnancy test of his hand and saw that it was indeed positive. Part of her was happy and part of her was terrified. Castle saw the perplexed look on Beckett's face so he reached his hands out and cupped her face, slowly moving in and gently kissing her lips. "I love you," Castle said to her as he pulled back from the kiss. Beckett looked more beautiful to than ever to him knowing that she was carrying his child. Beckett could see the pure happiness in his eyes. At that moment she know that her pregnancy was definitely one of those good surprises.
