First off thanks to all of my reviewers. I know I always thank you all personally but I thought it's time to thank you here too. Your reviews always put a smile on my face no matter how crappy the day is. So thank you very much that you take the time to leave a review.

Just so you know. I wrote the second paragraph already before the ep on Thursday. I'm a psychic. LOL. Enjoy!

Chapter 9: Saying good-bye

Lexie slipped into the gallery and sat down in the darkest corner. The room was packed with interns, residents and attendings. Everyone wanted to see Mark's first surgery after the coma. Most of them were there for support but there were also the haters. Mark was an extremely successful surgeon in his specialty and he never seemed to fail in the OR. Lexie could see in some faces that they were hoping that he would screw up. But she wasn't worried. Mark might be insecure when it came to his private life but professionally he never ceased to amaze her. It was a relatively easy procedure and he would perform it as if nothing ever happened.

Lexie never got tired of watching Mark in the OR during surgery. The calmness and confidence he radiated even now was incredible. As she looked down to him she remembered another time she had watched one of Mark's surgeries. The one where Sadie told her that Mark was checking out her ass. A small smile appeared on her lips when she recalled where this night had ended. With her knocking on his door followed by mind-blowingly fantastic sex. He definitely lived up to his reputation. But there was so much more to their relationship than just sex. They immediately connected on a whole other level too. They were soul mates.

Lexie clenched her teeth to prevent the tears from falling. Again. She had cried the whole night. It needed to stop. All of it. Therefore she had made that decision. The decision to leave Seattle and Mark. Maybe she could come back after some time had passed. So that wasn't very likely. She wouldn't be able to see Mark with another woman. Deep down Lexie knew that running away was the easy way out, that she should stay and fight for their love. But she couldn't do it. So she would run. But not without telling him. He deserved to hear it from her that she was going.

Lexie waited for Mark outside of the OR. When he opened the door and saw her standing there his eyes widened in surprise and a smile appeared on his face. But when he saw the redness of her eyes it fell immediately and was replaced by a worried expression. The feeling of sadness that had accompanied her since she had yelled at him in front of Joe's bar deepened even further when he looked into his eyes. She would never love anyone in her life as much as she loved him. How could she leave him?

Lexie balled her hands into fists while they were standing only a few feet apart from each other. No one wanted to make the first move, no one wanted to break the silence. Finally Lexie broke the eye contact and averted her gaze to the ground. When she looked up again she cleared her throat briefly before she asked Mark quietly.

"Do you have a second, Mark? I need to talk to you."

Mark looked at her for a few seconds before he silently nodded and Lexie hurried away to an on call room. When she shut the door behind him the room suddenly closed in on her. She couldn't talk to him in an on call room. There were just too many memories connected with these rooms. Memories that only hurt.

"Sorry, Mark. I ... I can't talk to you in here. I would explain it but I think this might be just a little too much information considering that you have no idea why I'm freaking out about you being in an on call room. With me. Alone." Lexie rambled.

"Lexie, I don't understand." Mark replied confused.

"I know. Just ... let's talk on the roof. Okay?" Lexie said quietly.

"It's freezing outside, Lexie."

"Oh … of course. We have November."

"I have no idea why we can't talk here but you feel clearly uncomfortable so let's go to the locker room." Seeing Lexie's eyes widen when he mentioned the locker room he furrowed his brows. "What? We can't talk there either."

"Yes. I mean no. We can't talk in the locker room. Let's go to the roof. We don't have to go outside. We can stay in the stairway."

After all they were no memories connected with the stairway. That was a Meredith and Derek thing. Mark and she always preferred close rooms where they can lock the door behind them. Maybe because they had never been able to keep their hands from each other. Especially after a fight.

Shaking her head to get rid of the feeling of Mark's hands on her Lexie left the on call room and went straight to the stairs pushing the door open she took two steps at once to get to the roof. She wanted to get it over with before she would change her mind.

Mark had no idea what happened that made Lexie all worked up. But he followed her without any further questions. He would find out soon enough. When they reached the door to the roof Mark leaned against the railing crossing his arms over his chest.

"Okay. I'm listening. What do you want to tell me?" Mark asked. Lexie gulped hard to suppress the tears that she felt were rising again. She would not cry in front of him again. She took in a deep breath fixating her eyes on his chest not able to look him in the eyes.

"I thought you should know. I'm moving to Boston."

"You are doing what?" Mark shouted angrily, his arms falling to his side, he took one step towards Lexie. Lexie's eyes shot up to his face when she heard the anger in his voice.

"Transferring to another hospital. I think it's the best for both of us." Lexie tried to explain while she retreated back until she hit the railing. Mark stood directly in front of her. His eyes full of fury and hurt. But when he realized that Lexie looked up at him with fear in her eyes he took two steps back and all the anger rushed out of him leaving him only with a feeling of betrayal.

"How can you leave me, Lexie?" Mark asked incredulously.

"Mark, please. Don't make it harder than it already is. I already explained it to you. Maybe I'm weak. But I can't deal with the fact that I'm the only one who remember our time together. You want to know why I couldn't talk to you in the on call room? Do you really wanna know?" Lexie didn't wait for his answer. She shoved her hand in his chest so that Mark stumbled one step back. "Because we had sex in there. Every free minute we had we met in an on call room and jumped each other. We had mind-blowingly fantastic sex with each other. But what hurts the most is that you can't remember that we also spent evenings where we only talked for hours. God, Mark. We are soul mates. At least we were. I could talk to you about everything. You always said the right things. You always knew what I was feeling."

Lexie stood in front of him panting, her body shaking with suppressed emotions. So Mark did the only thing he could think of right now. He pulled her into his embrace and Lexie buried her head into his chest. Inhaling deeply she smelled his scent and being in such close proximity she couldn't help herself. She slipped her fingers under his shirt and trailed them over his spine. Feeling his skin again after what felt like an eternity made her dizzy.

Mark tightened his arms even further around her when he felt Lexie's fingers on his skin. She barely touched him but he could still feel it. It definitely felt familiar. Holding Lexie in his arms. He knew that he had held her in his arms a million times like this. But he couldn't remember it and that's what was driving her away. He knew it was over when he felt her stiffen in his arms and he desperately tried to burn the feeling of Lexie in his arms into his memories.

It was over. Lexie knew she had to step away from him. Every second in Mark's arms would make it harder to leave. As she took a step back she let her hand slip around to his stomach and when she felt his abs under her fingers she could hear her heart break. She lost the love of her life and she would never be the same again.

The moment Mark lost the last contact to Lexie when she stepped away a feeling of emptiness overwhelmed him. Lexie looked one last time into his eyes before she turned around and started to walk down the stairs.

"The Lexie Grey I know wouldn't walk away like that." Mark said in a last attempt to change her mind. But when Lexie's eyes met his he saw that it was futile. She had made her decision. He would lose her. Forever.

"Well, that's the problem, right? You don't know me. So please. Just let me go, Mark."

They hold each other's gazes for a few seconds before Lexie turned around again and walked away. Mark stood frozen in his place. Something about seeing Lexie walking away from him was strangely familiar but he couldn't put his finger on it. The only thing he was certain about was that she took a part of his heart with her.

I'm already writing on the next chapter. So no threats please. :D I'm sure we are all still on a high after last episode because … it's over. Lexie is single again and we were told that Mark and Lexie are soul mates. Yiphhheeeee!
