Olivia woke up the next morning and got ready for work. She walked into the office finding Elliot already there along with Munch.

"Morning," Munch said as she passed his desk.

"Morning," she replied.

"Hey," Elliot said as Olivia sat down at her desk across from him.

"Morning."

Before he could say anything else Cragen came out of his office and presented the newest case to his detectives.

"397 97th a six year old raped and murdered," he said.

"Parents?" Elliot questioned wanting to know if and how they were involved.

"It's an abandoned building," Cragen answered.

The four headed out to the scene. They gathered their evidence and went back to the station.

"Any hits on missing persons?" Fin asked.

"Nothing," Olivia answered.

"So do we have any leads?" Munch asked.

"Just got one, parents reported a six year old girl missing an hour ago," Cragen said holding a paper as he came from his office.

"We're on it," Olivia said taking the paper from the Captain. Elliot and Olivia walked out and tried to ready themselves for a conversation with the parents.

They questioned the parents as if their daughter was missing, not letting them know that they had found a body earlier in the morning. The mother was obviously upset, the father not so much. The girls mother gave the detectives several items belonging to the girl so they could use them to get DNA in case they found a girl. Elliot and Olivia knew it was going to be used on the girl that they found.

"I'm liking the father for this," Olivia said as they walked out of the apartment building.

"Yeah, he didn't seem upset. I know if one of my kids was missing I'd be a little more upset."

"We need to get the DNA from the rape kit, see if there are any hairs on clothes or something that we got."

They went back to the station to see what Munch and Fin got from the lab.

"We got a hit in the database from the kit, Robert Jackson," Fin said.

"Robert Jackson?" Olivia questioned.

"Yeah why?" Fin asked.

"Robert Jackson is the father of the supposed missing girl," Elliot answered.

With Alex's go ahead all four detectives headed back to the apartment to arrest Mr. Jackson.

"NYPD open up," Elliot said pounding the door.

"Can I help you?" Mrs. Jackson opened the door.

"Where's your husband?" Fin asked as the detectives pushed into the apartment.

"In the den," she replied.

She pointed toward the den and Elliot was the first headed in that direction. When he saw him he grabbed him from the chair and pushed him up against the wall.

"Robert Jackson you are under arrest for the rape and murder of Rachel Jackson. You have the right to remain silent, anything you say can and will be used against you in the court of law. You have the right to an attorney, if you cannot afford one, one will be appointed for you," Elliot said to the suspect as he cuffed him.

Once they got to the station and presented him with the evidence he confessed to everything. Elliot and Olivia barely had to do more than show evidence. He said he did it because his daughter wouldn't stop crying and he lost it.

Once they put Mr. Jackson away it was time to call it a day. Munch and Fin had already left. Olivia had to run to the bathroom before they left. Elliot waited for her in the office.

"You okay?" he asked when she returned.

"A little nauseous."

They grabbed their coats and headed out.

"Is there something else?" Elliot asked seeing Olivia staring off.

"I don't understand how someone could do that to their own child. His wife had no idea that he would even hurt the girl. I guess I'm seeing things in a different light now."

"I never understood it."

"I see all this horror and I'm going to bring a baby into it all. It doesn't seem right."

Elliot put his hands on Olivia's arms and faced her.

"Olivia, we're in this together."

"I know. I'm scared," she said falling into his arms.

"Liv, I promise everything will be ok."

"Promise?"

"Yeah. Come on, I'll take you home."

Elliot parked the car in front of Olivia's building and got out so he could walk her upstairs. They got to the door and Olivia unlocked it.

"You want to come in?" she asked.

"If it's ok with you."

She led him in and closed the door behind him. Elliot said down in the recliner next to the couch. Olivia slipped over the arm and into Elliot's lap, immediately putting her face to his chest and starting to cry. He put his arms around her and let her cry for a while.

"Liv, what's really bothering you?" he asked when she started to calm down.

"I always imagined that when I had a baby I would be married and it was all planned out. I didn't want to bring a child into the world without a stable home for him or her to live. I didn't want it to live like I did."

"Olivia, I told you, I'm not leaving."

"What about your other kids? Is your divorce even final yet?"

"Not yet, but that has nothing to do with me. Wait, are you afraid Kathy and I will get back together?"

"You were married for 20 years."

"Olivia, you have my word, it's you or no one."

"What about the kids?"

"They are my kids, I'm not abandoning them. Kathy will keep them because of my schedule, but I will see them."

"What about us?"

"I love you, I have for a while. I want to be with you more than anything, but I understand if you feel otherwise."

"Seriously?"

"Have I ever lied to you?"

"No."

"Why would I start now?"

"What about work, I mean us as partners?"

"I know they have rules about couples being partners, but maybe since we are a specialized unit they may make an exception. Or maybe on the books we can split Munch and Fin and still work in the same station."

"You really think that would work?"

"It's really Cragen's call I guess. If he feels we can handle ourselves professionally he may push for it. It can't be a much different argument about people who have been partners for years. They care about each other, what makes us different?"

Olivia let out a small sigh and leaned her head back against Elliot's chest.

"Fell better?" he asked.

"A little bit, but this is all so new."

"A baby is a wonderful thing Olivia," Elliot said as he put his hands on Olivia's still flat stomach. "They change everything."

It was at that point that he realized she was asleep. He carefully picked her up and carried her into the bedroom. She didn't wake up at all.
