Mark took another drink of his scotch. He couldn't stop thinking about the conversation with Addison. Though he agreed to help her. He wished now that he had declined. He didn't know what she was planning.

"You look as though you lost your best friend" the woman sat down next to him at the bar.

Mark smiled at the pretty woman. "Normally I would be the one trying to pick you up. Unfortunately I have no time for a secret rendezvous" Mark looked at the woman. She was beautiful with her black shiny hair.

"There should always be time for a little fun" she laughed.

"Mark Sloan" he extended his hand.

"Lexie Grey" she smiled.

"Grey?" he looked at the girl once again.

"Yes"

Mark didn't think Meredith had a sister. At least she never mentioned having a sister. Maybe it was a coincidence. "My best friend is Meredith Grey. Are you related?" he asked realizing that Meredith was no longer his friend.

"This is a small world. She is my step sister. We have the same dad. Of course I just found out about her. She doesn't know that I exist." Lexie wanted to meet her. Thatcher had told her that it was better left alone.

"She doesn't know you exist?" he laughed. She would definitely not want to know.

"What brings you to the bar? You should be out with your boyfriend" he said.

"I just transferred to Seattle Grace. I start tomorrow it's my final year of residency" she was proud of the fact.

Mark almost chocked on his scotch. "Seattle Grace?" he hoped that he heard wrong.

"Yes" she laughed.

"Meredith is an attending at Seattle Grace" he warned.

"Yes I know" she had transferred on purpose.

"She will not throw you a welcome party" he warned once again.

"I know that. Listen my dad was terrible to her. I want to make up for that. I want to be her sister." she had thought long and hard over this. It was the only way she could get close to her.

"I hope that she gives you a chance." Mark liked the woman. Even if they had only just met.

"Maybe you could introduce us" Lexie needed someone on her side. Who better than her best friend.

"No can do kiddo. We used to be best friends. She will not give me the time of day now. Especially with you standing beside me." he took another drink.

"So she's the friend you lost" Lexie wondered if they were a little more than friends.

"Yes" he admitted.

"What happened?" she didn't like being nosy. She just wanted to find out about her sister.

"Let's just say I hurt the one she loves" he should have kept his hands off of Addison.

"If she really cares about you. She'll forgive you." Lexie said as she stood up.

"Where are you going?" he enjoyed talking to her.

"I have an early morning." she smiled. There was something different about this man.

"I hope I see you again" he would enjoy spending time with her. She reminded him so much of Meredith.

"You will" she smiled as she turned and left the bar.

Mark smiled. He felt like there may still be hope after talking to Lexie. Maybe his friends would forgive him. He definitely couldn't help Addison. He knew that Derek would never leave Meredith. He was happy that they were finally together. Whatever plan Addison had in store. He had to stop her. He had to get her to realize that she lost Derek. That he wouldn't come back to her.

He took the last drink of his scotch. He layed the money on the bar. Grabbed his jacket and set off to find Addison.

Addison sat in her hotel room. She had tried to call Derek. Of course he had finally turned off his cell phone. He was determined to ignore her calls. How could he be so mad. Especially when he lay with her. They were still married. He should be with her. Fighting to save their marriage. She didn't know Meredith that well. Had only met her once when Derek was head over hills in love with her. He was crazy if he thought that Meredith would give up her career for him. Some how she had to show him. Show him that Meredith would drop him for her career. Just like years before. She had left him torn and distraught. It had taken her a long time to fix what she had broken. Now he wouldn't give her the time of day. Swore his love for Meredith to her face. She wanted to scream at him. How could he be so cruel it was not the man that she married. In the little time that he had been in Seattle. Meredith Grey turned him into a cold hearted man. A man she could bearely recognize.

She jumped off the bed when she heard someone at the door. She prayed that it was Derek. That he changed his mind. That he would give her another chance. She ran to the door.

"Oh it's you" she turned away from the door.

Mark walked into her room. He had to get to forget about Derek.

"Addison I've been thinking. You need to move on. Let Meredith have Derek. They belong together." he saw the anger in her eyes.

"Your taking his side. After what you caused. You are going to sit and tell me what to do. What happened did you talk to Meredith?" she yelled.

"No of course not. What are you going to do? The man is done with you. There is nothing that you can say to win him back. Let it go." he pleaded.

"Go to hell Mark." she yelled throwing the pillow at his head.

"I am not doing this to hurt you. I really care about you. I know Derek and he's with her. There is no changing that now. You can not stay and play the victim. Not after what we did to him."

"It was a mistake. I deserve a second chance Mark. Do you want Meredith to hurt him. That's what will happen if we leave it alone." she cried.

"She will not hurt him. I'm sorry that you don't understand. If you are still planning on fighting for him. You are going to do it alone. I want my friends back. Helping you will push them farther away. That's not something that I want to happen."

"Fine if you don't want to help. I know someone who will jump at the chance. Someone who is not afraid to ruin this relationship." she yelled walking to the door. She held it open to get him to leave.

"Who would help ruin there relationship?" he didn't like the look in her eyes.

"It's out of your hands" she replied.

Mark shook his head. He didn't think anyone could destroy the love they shared. "Good luck" he walked out of her room.
