Olivia opened her eyes to the sun shining into her room. Her eyes were puffy from crying all night. She rolled over and William wasn't there. He left her and Evan. She pushed him away. She had to.

She got up and checked on Evan. He was still sleeping. She gently kissed him on the head and went to the kitchen. The sandwich William made her was still sitting there. She hadn't eaten all night.

She laid down on the couch and just stared at the ceiling. What the hell did she do?

Cragen heard a knock at his door. "Come in" he called.

Fin poked his head in. "Cap, you do know your stepson is sleeping upstairs right?"

Cragen raised an eyebrow. "What?"

He followed Fin out of his office and went upstairs. William was sleeping in one of the bunk beds in his jeans and t-shirt with his shoes still on. "William" he said loudly turning on the light.

William's eyes flew open. He looked over and saw his step father standing there. "Sir" he said sitting up.."I'm sorry; I meant to be out of here before anyone came in."

"What are you doing here?"

"I'm leaving, sorry sir." He headed toward the door.

Cragen stepped in front of him. "Why aren't you at home?"

"It's nothing sir." William tried to leave again.

Cragen once again stopped him. "What happened?"

"Nothing."

"Don't lie to me."

William looked down. "Olivia kicked me out."

"What are you talking about?"

"I'm as confused as you are." William answered honestly. "I told her I had to go to work for a couple hours and she started picking a fight with me-" He cut himself off when someone tried to come into the room.

Cragen grabbed the door, barked "Go away" and closed it again.

"Continue" he said evenly.

"She started picking a fight with me…Next thing I know she tells me to leave."

"I'm sure she didn't mean forever."

"I asked her that and she said she didn't care."

"Go home. Talk to her."

"Why? So she can kick me out again? Why the hell would I do that?"

Cragen smacked him upside the head. "Are you stupid?"

William rubbed his head. "No sir."

"Don't you realize what she deals with everyday here? She expects every father to be horrible. She's scared. Go talk to her."

William nodded. "Yes sir."

Casey sat in Olivia's living room looking extremely angry. "I hate men."

"Casey c'mon, It's not a big deal." Olivia spoke up as she fed Evan.

"He didn't show up all night, and you're saying it's not a big deal?" Casey got off the couch and paced around the kitchen. "Oh when I find him, I'm going to rip his throat out." There was a knock on the door. "Oh I hope he didn't forget his gun so I can shoot him in the balls with it." She went to the door and answered it angrily. "What!?"

Adam stood there looking confused. "Nothing" He gave her a strange look and tried to pass her.

She pushed him back. "You were probably in on this."

"In on what, Casey?" He looked at her strangely, "Are you losing it?"

"You're about to lose it, you and your little best friend." She moved closer to him.

"Casey", Olivia spoke up, "Let him in."

"Oh you're lucky." Casey warned him.

Adam raised an eyebrow and walked past her. "Hey Liv"

"Hey Adam" Olivia spoke up and put the bottle down. She put Evan on her shoulder to burp him.

"Is the Sergeant home?" He asked. Casey instantly smacked him upside the head.

"What the hell is your problem?" he said rubbing his head.

"Don't act like you don't know." Casey crossed her arms over her chest.

"Know what? What the hell's gotten into you?"

"William left."

"Left where?"

"Here"

Adam just stared at her. "I'm not following."

Olivia looked over at him. "He left me."

Adam raised an eyebrow. "No he didn't."

"Adam, we get you're kinda slow but damn." Casey retorted, shaking her head at him.

"No, I mean he didn't leave. He was at the base last night. When the Sergeant wants to disappear, he just disappears. He doesn't show up anywhere else. Why the hell would you think he left you?"

"It's a long story." Olivia answered.

The door swung open, William entered in almost a rush. He stopped seeing the two guests in their house. "Hi."

Adam looked around and instantly felt the tension and awkwardness of the room. "Well…I better get going. Have stuff to do." He glanced at Casey. "Case…you coming?"

Casey raised an eyebrow at William. "Yeah."

"Today?" Adam took her shoulder and practically pulled her out. He closed the door behind them.

William stood there and stared at Olivia. "Hi."

"Hi." Olivia said in almost a whisper. She got up and placed Evan in the crib.

"Can we talk?"

"About what?"

"C'mon…you know what. What happened last night."

"Why did you come back?" She crossed her arms on her chest.

"Because…you're the mother of my son. I'm not going to just pick up and leave you."

"He isn't your responsibility."

He took a deep breath and knew it was her way of pushing him away. "Don't say that."

"I'm his mother."

"And I'm his father. You can't raise him by yourself, a child needs his father."

"I didn't. You didn't."

"We didn't have a choice!" He quickly yelled and stopped himself not to wake up Evan. "I'm not leaving. I'm not going anywhere." He whispered.

"Why should I believe you? You didn't come back last night."

"I…I was confused."

She moved closer to him. "Yeah…what if you're scared again? When he is older and realizes what happens? What if you're so scared that you don't come back?"

He let out a deep breath. "Why are you doing this?"

"Because I don't trust you with him."

"What?"

Her eyes began to water. "You're going to leave for the war again…I know. I read the letter you got. You're being deployed."

William closed his eyes. "I was going to tell you." He whispered.
