Serena slowly came to and as she did she felt a sharp throbbing in her head. Her vision was clouded and she swore the side of her head was bleeding from the impact wound she knew she had.

As her vision came into focus, she finally was able to set her eyes on the smirking figure standing in front of her. "A-Alex? What're you doing here? How did you get in here?" Serena asked still dazed.

Addy smiled at the blonde tied to the chair in front of her. "Now Serena, is that a way to great your best friend?" she asked, her voice filled with a mock hurt. She saw Serena's eyes shift from her face to the knife that was harbored in her right hand. "Scared, Rena?" she teased again.

Serena quickly shook her head, "Why are you doing this? What have I done to you?" she asked, trying and failing to mask her fear. Addy simply ignored her and moved to where she was standing behind the chair.

"You know, I wonder what Abbie would say if I ruined you." she said quizzically. She took the knife and dug it into Serena's shoulder causing the blonde to shriek. Addy watched as Serena was squeezing her eyes shut as she dragged the knife from her shoulder all the way down her arm, stopping just before she got to the top of her hand.

"Not gonna scream huh?" Addy said as she moved and did the same to Serena's other arm. She watched as blood began to gush from both of the wounds and Serena began to sob at the pain.

She felt Serena stiffen as 'Alex' began to run her fingers through her hair. "Or what if I ruined you in a different way?" Addy whispered in her ear before she started placing delicate kisses up and down Serena's neck. She felt Serena stiffen again as she began to tug lightly on her earlobe nipping it with her teeth.

"Mmmm wanna know a secret?" she whispered into the petrified attorney's ear. She lightly licked the shell of Serena's ear before continuing. "I'm not Alex." She whispered.

Serena's eyes shot open at that statement. What did she mean she wasn't Alex? She began to tremble as she felt the coolness of the knife pressing against her throat. It was at that moment that she had wished that her last three words to Abbie were not 'I hate you.'

Days Later

"God this is going to take hours to go through." Olivia groaned as she, Alex, Munch, Fin, and Elliot, sat about to go through all of the notes they were finally able to obtain from Addison's apartment. "We have to. We need to find out where she is before she hurts someone else Liv…" Elliot said dropping a stack of papers in front of Olivia.

The five of them sat a table reading over ever scrap of paper they found in hopes that it would lead them to Addy's whereabouts. "God she was watching all of us." Alex murmured as she finished reading through a packet of papers that contained Abbie's routine schedule for Monday through Friday. She had already read Serena's and her own.

"I think I found somethin'." Fin said as he was filing through a stack of papers stapled together. "It looks like a list." Alex took it from him and read over it. She saw that on it was a list of names. First on the list was Connie's name, but it had a line drawn through it. Next was Abbie's name. It was underlined in red and out to the side was a childish frown face, but the name it self also had a line drawn through it.

She continued down the list glancing over Kim and Casey's names before she got to Serena's. Serena's name was circled and highlighted. Under it was Olivia's name, but there was nothing done to it. Alex gasped, "She's going after Serena." She said as she was making sense of the list. The detectives stood behind her as she explained.

"Look at this list. She killed Connie and Kim, and she tried to kill Abbie and Casey. It's the only way it makes sense. You have to go check on Serena." She rambled off looking up at them pleadingly.

The detectives nodded. "I'm staying here with you." Olivia said as the other three left the room. Alex smiled and placed a soft kiss on her lips. Olivia smiled back, "I'm going to call Abbie, see if Serena's alright."

Olivia stepped out of the room and dialed Abbie's number.

"Carmichael…" she heard Abbie's southern drawl bark through the receiver.

"Damn…are you not having a good day?"

"No Olivia, I am not. Serena's not here, AGAIN, she won't pick up her phone, so I am sitting her doing both her work and mine."

"I'm sorry….so you haven't heard from her? Has Casey heard from her?"

"No, I haven't heard from her, and neither has Casey. It still can't be because she's mad at me….could it?"

'I don't know Abbie. Well look, the guys are going over to her apartment, and so if she's there I'll call you and tell you okay?"

"Alright. Bye Benson. I've got work to do."

Olivia sighed as she heard Abbie hang up. All she could do was hope Serena was okay.

"Serena? You home?" Elliot called as he, Fin and Munch stood outside the door to her apartment. "That's weird, the guy at the desk said he hadn't seen her leave." Munch added. "Move." Fin shoved the other two out of the way as he made his way to the door.

He pulled a tool off his belt and began inserting it into the locks. "Are we even authorized to use those?" Munch asked. Fin turned around and gave him a look. "You wanna get in or not?" at that, Munch nodded and Fin continued.

Soon, the lock on the door slide open, and Elliot opened the door. As soon as they stepped into the foyer, the three men were met with darkness and a powerful stench that almost knocked them on their asses. "Oh damn." Fin winced as he covered his nose with his jacket. Elliot did the same, as Munch began to cough.

Reluctantly they flipped on the light, and were met with a sight they wish they hadn't seen. "Damn…." Elliot muttered. Munch sighed and shook his head. Fin could only frown and turn his head. "I'm going to call Melinda, and Liv." Elliot said as he exited the living room.

"You sure El? Alright…I'll tell her….No, no, I'll tell her too. Alright…do what you need to. I'll be here." Olivia sighed and ended the phone call. "What's wrong?" Alex asked, noting Olivia's sudden change in mood. "Serena's dead Alex…" was the whispered reply.

Tears immediately filled Alex's eyes though she was in shock. She felt like she was in a dream again. Serena was her best friend, and all of a sudden she was just gone. "She was my best friend Liv…" Alex sobbed as she rested her head on the detectives shoulder. "I know baby…I'm sorry."

Abbie dropped her phone and stared blankly into the nothingness of her office. She could only faintly hear Olivia calling her name on the other end of the phone. After what seemed like hours she finally picked up the phone again. "Yeah…I-I'm here." her voice began to crack. "Liv can you just, call some other time?"

She sat her phone down on her desk and put her head in her hands as the tears began to flow freely. Abbie Carmichael never cried, but damnit she didn't care anymore. She glanced at the picture of her and Serena that sat on her desk. She cried more at how happy they looked in the picture, and in reality her last words with Serena were a fight.

Abbie opened her desk door and took out a velvet black box. She was about to open it when Casey stepped into her office. "Hey Abbie, I finished everything I needed to do so I was wondering if you needed any help with anything….what's wrong? Why have you been crying?" the redhead asked.

"She's gone Case…" The brunette's whisper was so low that Casey almost missed it. "Who's gone? What happened?" she asked again sitting in a chair across from Abbie's desk. "Elliot and the other's found Serena in her apartment this morning…her throat was slit." Abbie concluded.

Casey gasped and put her hand over her mouth. "Oh my god. That's….oh my god…." Was all she could say. She watched as Abbie picked up the box. "What are the odds of this happening?" the brunette asks bitterly. "I finally get my ass in gear, and I'm going to ask her to marry me, and she's fucking killed. What are the fucking odds." She slams the box down on her desk.

Casey reaches over and opens it. "It's beautiful..." she said examining the diamond encrusted band the shone perfectly in the light. "She would have loved it." Casey stated softly.

"The last time we spoke was a fight Case…You know the last thing I said to her? I called her a bitch. I made her cry that night Casey. And she told me she hated me. Now I'll never see her again, and I'll never forgive myself for that."
