Olivia got up and instantly smelled coffee and food. She wasn't used to that unless she was in William's apartment. She went out and spotted Casey in the kitchen making food. "Case you cook?"

"Sometimes." She answered. "For boyfriends or my pregnant friends."

Olivia smiled. "Thanks." She went to the kitchen and poured coffee. Casey instantly grabbed it. "What are you doing?"

"You're pregnant. You can't have coffee."

"Right." Olivia nodded and got orange juice. "Hey can we keep this pregnancy thing away from work? I don't want the guys to know yet."

"Sure. What about Cragen? I mean it is his grand kid in there."

"I'll figure that out. Just don't tell anyone for now."

Casey nodded and put a plate of food in front of her. "Enjoy mommy."

Olivia smirked and sat down. "Thanks." She began eating the food as the lawyer sat across her and ate her breakfast also.

--

Olivia knocked on Cragen's door slowly. She came in hearing approval. "Hey Cap, can I talk to you?"

"Sure." He put his pen down. "Everything ok?"

She came in and closed the door behind her. "Yeah. Just needed to talk."

"Of course. What's up?"

She sat across him. "Well…you know William and I are dating right?"

He smiled. "Yeah."

"I sort of found out I'm pregnant."

He raised an eyebrow. "It's William's?"

"Of course."

"He will take responsibility for it, don't worry."

"I know. I already talked to him about it."

He nodded. "Anything else?"

"No. I just wanted to let you since you're technically the step grandfather." She smiled. "That's all."

"Thank you. If you need anything let me know."

"I will." She got up. "Thanks." She waved a little and left the office.

--

Six months later…

Olivia and Elliot were sitting in a restaurant eating. "Any names?" Elliot questioned.

"I didn't really think about them yet. I haven't talked to William in a couple days."

"Olivia you know you have to make some decisions. You don't know when William will be back from Iraq."

"I know."

"Donald Junior?" Elliot smiled.

"No way." She shook her head. "Calix?"

"Ew."

"Calvin?"

Both turned around and spotted Casey coming into the diner. She sat down next to them. "No Calvin." Olivia answered. She touched her stomach that was well grown. "I want this baby boy to have a strong name."

"Elliot." Elliot teased.

"No thanks. I said Strong, not overrated." Olivia smiled.

"Jonathon." Munch came in and sat down by Elliot.

"I'm not naming him after any of you." Olivia declared. She noticed Casey was grinning at her. "No. I'm not naming my son Casey."

"It's a unisex name though."

"Don't care." Olivia shook her head and started eating again.

Cragen came in and sat next to Olivia. "Hey." All of them nodded at their boss. He handed Olivia a letter.

Olivia took it and looked over it. A smile came across her face. "Today?"

"Yup. I just got it in the Fax." Cragen smirked. "Coming with me?"

"Of course." She nodded.

"What's going on?" Elliot questioned.

"William is coming back today." Olivia answered with a huge grin. All of them cheered a little.

--

Olivia and Cragen sat impatiently at the naval base along with other families. "Excited?" Cragen questioned.

"Extremely." She answered. "Nervous also."

"Why?"

"He just hasn't been around me when I'm pregnant."

Her captain smiled a little. "Don't want to have mood swings?"

Olivia looked over at him with a teasing smile. "Actually yeah. I don't even know how he will react."

"Well he knows you're pregnant."

"I know. I'm just excited to see him again."

Cragen gently patted her knee. "It will be ok."

"Thanks Don."

"No problem." He smiled his fatherly smile. They saw a charter bus pull over. Everyone got up and moved closer.

A bunch of marines got out and instantly stood in formation.

Olivia looked around but didn't see William. He was the last one to get out of the bus and stand in front of his soldiers.

"Thank for serving your country men." William saluted them. All of them saluted back. "Dismissed."

All the marines quickly went to find their family.

Olivia grinned and slowly walked over to William who was shaking hands with a soldier. They saluted. William turned around and spotted Olivia. He instantly grinned. "Hi."

"Hi." She pulled him into a hug. She didn't say anything and just started crying on his shoulder.

"It's ok baby." He whispered. "I'm here now." He gave her a couple kisses on her cheek.

"I know." She let go of him and wiped her eyes. "I'm just so happy you're ok."

"I'm fine." He nodded with a smile. He looked down at her stomach. "Wow."

She took his hand and placed it on her stomach. "Meet your son."

He stared at it in amazement. He kneeled down and gently kissed her stomach. "Hey man." He whispered to her stomach. "I'm your daddy." He gave it another kiss and got up. "You look so beautiful." He hugged her again.

Olivia laughed a little and gave him a kiss. "Don's here also."

He let go of her and looked around. He spotted his step-father waiting. "I'll be right back." He told Olivia and walked away to Cragen. "Nice seeing you again sir."

Cragen got up and shook his hand. "You too. You're going to be a dad now."

William smiled and nodded. "Yes sir. Is it normal to be shaking of fear?" He looked down at his shaking hand that he touched the stomach with.

"Pretty normal."

"Good." William smirked. He felt someone touch his back. He looked over and spotted Olivia. "Hey." He put his arm around her. "Ready to go home?"

"Of course." She nodded. "Someone was looking for you though." She pointed at a woman standing by herself. He took a deep breath and took off his military issued hat.

"Her son got killed. Excuse me." He walked away from them and went over to the woman.

Olivia and Cragen just watched. He spoke to the woman for a couple minutes. In a matter of seconds, the woman was crying in his arms. He had his stern expression on his face like always as he held the crying mother.

A couple minutes of that, someone finally came over and took the woman. William thanked them and walked away.

"You ok?" Olivia questioned.

He nodded and grabbed his gear. "Fine. The kid was going to be twenty in a week." He answered and walked past them.

Olivia and Cragen exchanged looks and followed him to the car.

William was quiet the whole car ride home.

--

They finally arrived at Olivia's apartment. William neatly put his gear and bags down in her room. Olivia watched with a smile. "Still neat huh?"

"Yes m-" He cleared his throat realizing he didn't need to call her ma'm. "Yes."

She let out a small laugh. "Want to take a shower?"

"Yeah." He nodded and started to take off his uniform. He folded it and put it across the chair.

She walked in and pushed him on the bed. "I'll help."

He raised an eyebrow. "Oh. Ok."

She kneeled down in front of him and started unlacing his combat boots. "How are you not sweating like a pig in this?"

"Got used to it I guess." He shrugged. "You don't have to undress me. Should you even be kneeling down? You're pregnant."

"I'm fine. Don't worry." She took off his combat boots and threw them to the side.

"Oh c'mon don't make a mess." He complained.

"Shut up."

"Ok." He nodded and laid back. "I'm not cleaning it though."

She undid his belt and pulled his pants down. "Just shut up and relax." She sat down on him and pulled him up. She pulled his brown t-shirt off and threw it to the side. He opened his mouth to say something again. She started kissing him before he could.

--

William stared at the ceiling with Olivia lying in his arms. He couldn't sleep from the nightmares he was having while in Iraq.

Olivia shifted a little and woke up. She looked up at him with a small smile. "Can't sleep?"

"No." he answered and pulled her closer. "Why you up?"

She took his hand and placed it on her stomach. "He has a tendency to kick and wake me up."

He felt his son kick. A grin appeared on his face. "Wow. That's amazing."

She smiled and nodded. "Yeah. Did you think of any names?"

He nodded. "I have a favorite one. Charles."

"Ew Charles?" Olivia raised an eyebrow. "I feel like we are in the Royal British family here. William and Charles."

He shrugged a little. "I just like that name."

"I'll think about it." She smiled and gave him a kiss. "We have time to talk about the name now though."

"About that." He sat up a little. "I'm not here permanently."

"What?" She looked at him.

"I have to go back in two weeks." He answered. "I'm technically here on business."

She sat up. "What are you talking about?"

"They needed someone to talk to the generals and corporals in the main office. I begged them to let me so I can see you. Experience the pregnancy thing before you gave birth."

She shook her head. "You're unbelievable."

"Olivia I'm sorry." He pleaded. "I was going to tell you earlier."

"Forget it." She shook her head and sat on the edge of the bed. She found her panties and pulled them on. "I thought it was ok that you missed six months of the pregnancy since you were going to be here for his birth but now you're leaving again."

"C'mon Olivia." He tried to take her hand. She pulled it away. "I wish I was here. That's my son too."

"Some father you will be. He isn't even born yet and you're already not here for him." She pulled on a t-shirt.

He just stared at her. "That's not fair."

She turned to look at him. "Not fair? You want to talk about fair William? I had to go to the doctor myself for six months. People think I'm some whore that got knocked up by a one night stand. Do you know what it's like to be the only one in the doctor's office not to have a husband or boyfriend sitting next to you holding your hand?"

"I'm sorry." He whispered.

"Who am I kidding right? Maybe you are just a one night stand and this baby got in the way." She snapped.

He shook his head. "I don't really need to deal with your PMS the night I came home."

"PMS?" She questioned angrily. "Don't you dare." She grabbed a pillow and blanket. "I'm sleeping on the couch."

"Wait." He called over. He got out of bed and pulled on his boxers. "You're pregnant. Take the bed." He took the pillow and blanket. "I'll sleep on the couch." He walked past her.

Olivia said nothing and went to sleep on the bed.

William lay down on the couch and once again just stared at the ceiling.

--

The next morning, Olivia woke up to knocking on the door. She got up and left the bedroom. William was in a deep sleep so he didn't hear the knocking.

Olivia opened the door and spotted Casey standing there with bag full of food. "Good morning sunshine." Casey smirked but noticed Olivia wasn't in a good mood this morning. "Who rained on your sun huh?"

Olivia shook her head and went inside leaving the door open for her best friend. She glanced at William sleeping on his stomach. He was shirtless and had the pillow folded under his muscular arms. She went to the kitchen.

Casey closed the door behind her and followed. She stopped seeing a half naked man on her friends couch. "Hottie alert." She announced and pointed to William's tattoo on his back shoulder.

Olivia smirked and sat down on a stool in the kitchen. "That's William."

"I should get me a marine." Casey stated and put the food on the counter top. She opened a cabinet to get plates. By accident, the door slipped from her grip and loudly slammed shut.

William instantly jumped and breathed hard.

Both women looked over at him. "Sorry." Casey stated.

William sat there for a few seconds and wiped the sweat off his face. The sound reminded him too much of a bomb. He looked over at the women staring at his traumatized look. "Hi."

"You ok?" Olivia questioned. Though she was mad at him, she still cared.

He nodded. "Yeah." He got off the couch and realized he was shirtless in front of company. "Excuse me." He went to the room and closed the door.

Casey looked over at Olivia with a grin. "You lucky bitch. I hate you."

Olivia laughed a little. "That good looking?"

"Are you kidding me? The man has like a twelve pack and an ass of steel. Adorable face too."

"Yeah." Olivia agreed. "If I wasn't your friend, you would be such a home wrecker."

"Home wrecker with the heart of gold baby." Casey teased with a wink.

William came out of the room in a marine t-shirt and jeans. His hair was nicely fixed now. "Sorry about that." He put his hand out to Casey. "William Grant."

She smiled and shook his hand. "Casey Novak."

Olivia smirked as she at her cereal. "Casey has a crush on you." She stated.

Casey started blushing extremely and looked over at her friend. "What? Shut up. I do not."

William blushed a little. "Thanks I guess." He walked past her and looked for a coffee cup. "Liv…where are your cups?"

"Can't go without coffee for two weeks?" Olivia teased bitterly.

He glared at her and looked over at Casey. "Ms. Novak, a little help?"

"Sure Mr. Grant." Casey grinned and got him a cup.

"Thank you ma'm." He poured coffee for himself.

"My pleasure sir." Casey smiled even more.

Olivia rolled her eyes. "Why don't you two just get married?" She mumbled and ate her cereal.

"You're having his baby." Casey answered in her goofy manner. "I'm not into that weird thing."

Olivia rolled her eyes. "Whatever."

William sat down by Olivia. "You don't have to take your anger of me out on your friend you know?"

"So now you're defending her?" Olivia looked over at him. "You should stop worrying about her and be more worried about yourself."

"Are you threatening me?" William questioned.

"Yes I am. What are you going to do? Shoot me down? Apparently that's what you marines are good for."

He stared at her for a couple seconds. "I'm not dealing with you." He got up. "I'm going to my own apartment." He went to the room and grabbed his stuff. "I will support my son in any way possible but I will not let you threaten me or treat me like some piece of crap you can step on."

"Whatever William." She rolled her eyes. "You're good at walking away when it gets deep aren't you?"

He stopped and turned around. "And for the record, this is why no man puts up with you. This is the reason you can't keep a relationship. It's not your job sweetheart, it's you." He stated. He looked over at Casey. "Nice meeting you ma'm." He turned around and left the apartment.

Casey just stared in amazement to what just happened. She wasn't sure why this couple just broke up but it happened. "He wasn't that hot anyway."

Olivia pushed her cereal away and put her head down on the table. "What did I do?" She whispered.

Casey sat down by her. "It's ok." She rubbed her back. "Are you crying?" Olivia shook her head. "Liar." She pulled her into a hug and let the detective cry on her shoulder. "He will realize it was just PMS and he will come back. He seems too nice to just walk away from his own child."

She nodded as tears rolled down her face. "He is very nice. He even went to sleep on the couch so I didn't because I was mad. I'm so stupid."

"I know. It's ok." Casey held her.

Olivia smiled a little. "Thanks Case."
