Why was he here? Did Alex and Casey have something to do with this? She couldn't believe it. She was looking him right in the eye and she had no idea what to say. She turned and tapped Casey on the shoulder.

Casey turned and looked at her and watched Olivia's signal to look behind her. When she realized who was sitting behind her friend her jaw dropped. She immediately turned to Alex and mimicked Olivia's actions. Alex looked at Casey, then at Olivia, and then at the man sitting behind her friends.

She looked at Olivia with a slight smile and then whispered, "There's a reason you ended up sitting next to him. Maybe it was meant to be." She winked and then turned back and continued flirting with the guy on her left.

Casey turned back to Olivia and said, "Take advantage of this moment." She got up and went to find someone to dance with.

Olivia turned back to the man sitting to her right. They just stared at each other, unsure what to say.

He finally decided to break the silence. "Hey Liv, long time no see." He said as he looked nervously into her eyes.

"It's not Liv, its Olivia. You lost that privilege when you walked out of that squad room two years ago without even saying goodbye." She said with an angry look on her face.

"I can explain-"He started to say but he was cut off.

"No. You had your chance to explain every time I called you for a month after you left. I gave up because you refused to answer. I was going to just go to your house but I figured if you wanted to see me, you would've."

"Olivia, I was going to call you but-"

"No. You don't get the chance to explain yourself. You hurt me, Elliot. You left without even a goodbye and then you wouldn't answer my phone calls! You were my partner, my best friend. You were always supposed to be there and then you just up and leave. No explanation, no phone calls, no goodbye. You should've come to me when you had the chance." She went to get up and he grabbed her arm.

"Please don't leave." He asked in almost a whisper.

"Why would I do anything for you?" She said as the tears filled her eye. She was fighting to hold them back but she was losing the fight.

"Don't cry, Olivia. Please don't cry." He said as he went to wrap his arms around her.

"Don't. Just, don't." She said as she walked toward the ladies room. When Casey realized Olivia had gotten up, she followed her. Alex followed closely behind.

"Hey, Liv?" Casey said as she slowly opened the door to the bathroom. She could hear sobbing coming from one of the stalls.

"Hey Liv, honey come out here so we can talk to you." Alex said as she walked over to the stall their friend was sitting in.

Olivia opened the door and Casey pulled her into an embrace. "Livvy, I'm sorry. I wouldn't have brought you here if I knew he was going to be here." She said as she rubbed Olivia's back.

"I know." Olivia said as she pulled away. "I thought I was okay and that I was over it but seeing him again brought up so many memories."

"We can leave if you want." Alex said as she gave Olivia a hug.

"No, I want to talk to him. I want to know why he did what he did. You guys can go, I'll be okay."

"Call us if you need anything." Casey said as she rubbed Olivia's arm.

"I will." She said giving them a small smile as she opened the door to the bathroom.

The next thing she knew, she was back at her seat looking at Elliot.

"Can we go somewhere else? We need to talk." Olivia asked; you could see that she had been crying.

He just nodded and followed her out of the club.
