Last Time:

Casey must've fallen asleep on the couch because she was woken by the sun's ray shining through the living room window on to her face. She then noticed that Olivia was asleep beside her on the couch, looking very uncomfortable on the edge.

"Liv, wake up." Casey spoke softly as she gently shook her.

Olivia's eyes fluttered open and she looked up at Casey. "Hey."

"Hey. How long have you been lying here?"

Olivia looked at the clock. 6:02am was clearly displayed.

"About an hour. I woke feeling sick so I took some tylenol and I needed some company but I didn't want to wake you up." Olivia explained.

Casey nodded. "Are you ready to tell me what is eating you up inside?" She asked cautiously.

Olivia nodded and took a deep breath. "Yes, I think I am."

-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-O-

After a couple of minutes of silence, Casey decided to speak up. "Liv, look at me. Whatever it is, I promise you that I won't hate you." Casey spoke in a soft, honest tone to her best friend.

Olivia inhaled and exhaled slowly and deeply as she ran a shaky, olive toned hand through her soft brown hair. "I...Ah...I..." She stuttered before getting up.

She began to pace around her living room. Casey stood up and walked over to the brunette.

"Stop, Liv. Stop. Tell me what is eating you up inside." She spoke as she stopped Olivia from pacing around.

Olivia took a shaky breath. "No. Forget about it." She said before trying to rush off to her bedroom.

Casey gently grabbed her wrist. "Liv..."

Olivia slowly nodded so Casey guided her back to the couch and they both sat down.

"Ok, let me talk with any interruptions."

Casey slowly nodded. She really wanted to know what was troubling the tough female detective.

"I...I found out that I'm not actually a child of rape. I was just an accident after a college party."
"When did you find this out, honey?"

"A couple weeks ago."

"How?" Casey asked slightly confused since Serena Benson had passed on years before.

"I went through an old box that I had hidden in the back of my closet and I found a letter written to me from my mother, when I was just a baby." Olivia explained.

Casey slowly nodded. "Have you still got the letter, Liv?"

"Yeah." She responded and got up off the couch to get the old letter from out of the drawer beside her bed in her bedroom.

Olivia returned about two minutes later with an old, discoloured envelope. She sat back down on the couch beside Casey and passed her the envelope.

Casey slowly nodded and silently took the envelope form her best friend's hand.

'Olivia' was handwritten in neat cursive on the front.

Casey opened up the envelope and pulled out a piece of old discoloured paper, opening it up to read it.

As Casey read the letter, Olivia couldn't sit still so she got up and began pacing around again, biting her finger nails, nervously.

There was more in the letter then what she told her best friend.

The letter read:

'My beautiful Olivia,

By the time you read this I will be gone. Right now as I write this letter, you are only ten days old and my secrets are already eating me up inside.

You aren't a child of rape, I'm sorry for lying because I already know that I will lie to you. It's a complicated situation but to tell the story short, you were conceived after a drunken night at a college party. I also have another secret. You have an older sister named Sarah Marie. She is two years old then you and I gave her up for adoption. Why not find out where she is and get to know her, I am sure that she would love to meet you.

Olivia Serena Benson, take care of yourself and just remember that I love you. I'll be looking over you from up in Heaven.

Until we meet again,

Mom.'

"Wow." Casey said in surprise as she put the letter down on the coffee table and looked up at Olivia.

Olivia was looking at anything but Casey as she continued to pace around.

The red haired ADA got up and stood in front of the detective, to stop her form pacing around.

"'Livia, look at me, honey." She spoke softly.

Olivia looked in to her best friend's eyes as requested and waited for her to say what she wanted to say.

"Olivia, why would you think that I would hate you after finding out this information?" Casey asked gently in slight confusion.

Olivia shrugged. "I thought that everyone would think that I was lying about it, plus Elliot made everything worse."

"What did he do, Liv?" Casey wondered since she had walked out with Fin at the time when Elliot read a page of Olivia's private diary.

"Forget it, Case." I have things that I have to do today." Olivia insisted before rushing off in to her bathroom, locking the door behind her.

-O-O-O-O-O-O-O-O-O-

Casey waited until she heard Olivia turn the shower on before deciding to leave, knowing she wouldn't get anymore information out of Olivia for the day.

The red haired ADA walked out of Olivia's apartment building to see Elliot standing beside a detective car, waiting for her.

"Morning Elliot." She said as she walked over to the detective.

"Hey Casey. Is Liv alright?" He asked concerned.

Casey sighed as she rubbed her neck, which was sore from sleeping on Olivia's couch all night. "She's confused right now, Elliot. That's all I am saying, if you want to know more, you need to ask Liv but not right now."

"Why the hell not?" Elliot asked, slightly ticked off.

"Because she won't tell you anything right now, trust me." Casey explained to him before calling out for a taxi.

"Come on, Casey. I will give you a lift home." Elliot said in defeat, knowing that he wouldn't be able to talk to Olivia.

"Thanks, Elliot." She thanked him as they got in to the car.

-O-O-O-O-O-O-O-O-O-O-

Inside Olivia's apartment, she got dressed in light blue jeans, a long sleeved pink and white stripped top with black boots. Her hair was tied back in a neat pony-tail and her make-up was done. She grabbed her purse and keys as she rushed out of her apartment, locking it behind her.

Olivia Benson needed her job and she knew that she had to have counselling to keep it. The first on her 'to do' list for the day was to see Dr George Huang, so she got in to her car and started the engine before driving off in the direction of the FBI building.

Olivia drove in silence, besides U2 playing on the CD player in the background. She pulled in to the parking lot and parked her car before heading in to the building, to Huang's office.

Olivia took a deep breath before knocking on the door.

KNOCK. KNOCK. KNOCK.

"Come in." A voice called from inside of the office.

Olivia wasn't happy about this but she knew that it was necessary to keep her job so she opened the door and silently walked in.
