Olivia sat at her desk in the squad room late that night. The room was dark with only her desk light lit. She looked over the notes that she had taken on the case. Warner had submitted her autopsy 

reports earlier in the day, and CSU had also run a number of tests on the crime scene. She glanced at her watch-9:53 before taking out the folder with the Voschel family's financial statements. Cragen walked into the squad room and stopped as he noticed Olivia at her desk. He walked over slowly causing her to look up.

"You do know that it is ten o'clock right?" he said walking toward Olivia's desk. "Even if you find something there's nothing that you can do tonight." Olivia sighed before looking back down at the paperwork in front of her. After a few seconds Olivia's eyes showed that she had found something. "What?" Cragen asked noticing that Olivia's expression had changed.

"When Allison's mother and stepfather separated, they eliminated their joint bank account and each opened a new one in their name," Olivia said.

"Which is understandable," Cragen said, unsure of where Olivia was headed.

"Near the end of every month, Morrison withdrew a hundred dollars out of his own account, and within a few days Allison deposited a hundred dollars into the account that her mother opened up for her," she said handing him the bank statement.

"He was paying her off," Cragen suggested as he looked at the paperwork. "For what?"

"Allison was just under three months pregnant when she was killed. Her mother left Morrison in October, where the payments start. What if Morrison was paying her off to keep her quiet about her pregnancy," Olivia suggested.

"Because it's his baby," Cragen said catching on.

"Warner's report says that Allison's body shows signs of repeated sexual abuse. If Allison's mother finds out about her soon to be ex-husband raping her daughter, it not only gives her more leverage in divorce proceedings but sends the bastard to jail," she added.

"At three months, Allison realizes that she is running out of time to hide her pregnancy and threatens to tell her mother about Morrison. He tries to negotiate with her but she doesn't budge and he kills her," Cragen formulated handing Olivia the bank statements. Olivia nodded setting the statements back down on her desk. "Talk to Casey in the morning about getting Morrison's DNA to test against that of the baby," Cragen said. "Go home Olivia, get some rest."

"Okay," Olivia sighed before turning off her desk lamp and standing up. After saying goodnight to the captain, Olivia flipped open her cell phone and dialed Mark's number. She walked out of the squad room as she waited for Mark to answer.

"Hello?" Mark said into the receiver after grabbing his ringing cell phone off of the bedside table.

"Hey babe," Olivia said softly, fearing that she may have woken him up. "Did I wake you up?"

"No, I'm just laying here watching tv in bed. Where are you?" he asked as he turned down the volume to the tv.

"Oh, I'm just leaving the office now. It's been kinda a crazy day," she said walking into the elevator.

"Awe, I'm sorry sweetie. Why don't you come over and lay here with me to take your mind off of it," he said. Olivia smiled as the elevator doors closed.

"Ok, I'll be there in a little bit."

"The door is unlocked so just come in," he told her.

"Ok, I'll see you soon," she said stepping out of the elevator.

"Alright, I love you."

"Love you too," she said as she stepped out into the cold December air.

Twenty minutes later Olivia walked down the hall toward Mark's apartment. She quietly opened the door to Mark's dark apartment. "Olivia!" Mark called from the bedroom down the hall. Olivia set her bag down on the floor by the door and walked down the hall, where she found Mark sitting up against the headboard, the TV on.

"Hey," she said walking further into the bedroom.

"Hey babe," Mark said scooting off the bed as Olivia took off of her jacket and set it on the armchair in the corner of the room. "Rough day?" he asked before kissing her lightly.

"You have no idea," she said as she wrapped her arms around his neck. She felt his arms tighten around her waist. After a few moments they parted, and Olivia kissed Mark lightly before unbuttoning her red collared shirt revealing a white camisole which hugged her body tightly. "There are so many things going through my head right now, all I want to do is like lay with you to get my head in better place." Mark jumped backward onto the bed dramatically, causing Olivia to laugh as she lowered her jeans, revealing red lace underwear.

"Well at least I got you to smile," he said. Olivia smiled as she stepped forward and bent down, kissing him. She felt his hands of her jaw as the kiss deepened. She leaned forward causing Mark to lay on his back as she kneeled on the bed, continuing to kiss him.

Olivia stirred as the alarm on her phone rang from the bedside table. She lifted her head off of the pillow and reached over, turning off the alarm. She noticed she sat up in the bed that she was alone. After rubbing her eyes she good out of bed and walked across the room to the dresser. She opened the top drawer which was filled with some of her clothes that she had kept at Mark's place. She pulled out a pair of jeans and a black, button up collared shirt. She laid them on the bed and walked out of the bedroom and through the apartment where she found Mark leaning against the counter, already dressed for work.

"Morning baby," he said softly as Olivia walked toward him.

"Morning," she said as she kissed him lightly. "Do you care if I take a shower?"

"Not at all. I have a meeting in like a hour so I'm going to be leaving here shortly. The door will lock when you leave," he explained.

"Okay. I shouldn't be too long."

"Take your time. Call me after work and maybe we'll do dinner tonight," he said rubbing her hip.

"Okay," Olivia said with a smile. "Have a good day at work." She turned to head back to the bathroom but felt Mark grab her arm and pull her back toward him. He leaned in and kissed her, and watched as she smiled when they parted.

"I love you," he said softly.

"Love you too," she said before turning again toward the bathroom.

"Call me," he called.

"I will," she called back as she walked back down the hall.

Olivia and Elliot sat in Cragen's office as they waited for Warner to call confirming that the baby's DNA matched Eric Morrison. Elliot sat in one of the chairs in front of Cragen's desk while Olivia's paced back and forth, stopping in front of the two way mirror. They had already interrogated Morrison who had denied the accusations against him.

"What the hell is taking so long?" Olivia asked anxiously. But just as Olivia asked, Cragen's desk phone rang.

"Yeah," he said into the receiver. Olivia and Elliot watched anxiously as Cragen listened to whoever was on the other end. Casey slowly walked into the office, and paused after noticing the silence. Cragen hung up the phone, and stood up. "We got the bastard. DNA from Eric Morrison matches that of Allison's baby." Olivia clenched her jaw in satisfaction.

"We still don't have enough for charging him with the murder, but plenty for the rape," Casey announced. "Arrest him." Elliot and Olivia nodded before walking out of the captain's office. They walked out of the squad room and down the hall into the interrogation room where Morrison was being held. Elliot opened the door, and nodded to the officer who was standing in the corner.

"Stand up," Elliot said forcefully to Morrison who was seated at the table. Morrison obeyed, but stood up slowly. Elliot walked over behind him, grabbing his wrists, pulling them behind his back.

Olivia walked forward and stopped in front of the table so that she was directly across from Morrison. "Eric Morrison, you are under arrest for the rape of Allison Voschel. 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 any attorney. If you cannot afford an attorney one will be appointed to you by the court. Do you understand your rights as I have read them to you?" She followed Elliot, who had a tight grip on Morriscon, out of the squad room. "Do you understand you rights?' she asked more forcefully.

"Yes," Morrison said in a defeated tone. Olivia smirked as she followed them into the squad room, where Morrison was printed and booked.

By six o'clock, Morrison was arraigned and sitting in Rikers and the unit was in celebratory mood. Elliot, Olivia, John and Fin walked into the squad room after Morrison was arraigned. "Anyone up for a drink?" Fin asked as he walked over to his desk. Just as Olivia was about to answer, her cell phone vibrated from inside her jean's pocket.

"Hello," she said into the receiver.

"Hey babe," Mark said on the other line.

"Hey, hun what's up?" she said as she walked over to her desk.

"Not much, I just got out of a meeting with a client who is very interested in our company," he said. "So I'm on my way back to the office to fax a couple of things over to my boss and then I get to spend the night with my most amazing girlfriend." Olivia smiled as she grabbed her purse out of the bottom door of her desk. "How's the case?"

"Finished. We are all about to go out for some drinks to celebrate," she said. "How long are you going to be?"

"I don't know. I'll probably be out of the office by seven. Where are you guys going for drinks?"

"Um, probably McKibbins," Olivia answered.

"Do you just want me to pick you up there after I leave the office?"

"No, don't worry about it. I'm just going to go for a few drinks and then I'll take a cab and meet you for dinner," Olivia said.

"Babe, it's no problem. It's like ten minutes from the office. I'll come when I leave."

"You sure?" she asked.

"Positive. Go with the guys and I'll see you in a little bit sweetie, okay?"

"Alright, I love you," she said smiling.

"Love you too."

Olivia closed the lid of her phone as Cragen walked out of his office. "We going or what?" he said. The group laughed and walked out of the squad room.
