So this sets place after 07x02 .

I don't really like the fact that Lexie told him to leave. And I'm afraid Mark & Amy ( Derek's Sister who'll appear next episode) will have an affair or something. I know I'm still having this other story but I just had to write this. oh & some reviews would be awesome , really :D

From the very first moment Lexie told Mark to leave her alone, she regreted what she said.

She loved him, she really did. And she didn't want him to leave her alone, forever. Just for the moment she had to be the strongest person in her life. And she was sick of everyone treating her like she was delicate or something. Of course she knew he just was scared about her and only wanted her to help feeling stronger but she couldn't deal with this right now. But how she explained herself to him, it sounded all wrong. But now she couldn't turn this around anymore. He was avoiding here naturally. And she knew that wouldn't change so far.

It was about a week later, when Lexie finally realized he was worth fighting for. But now it might be too late.

She was just searching for the medical file of her new patient Charlaine Cory when she saw a young hot women hugging Mark. The women, well she barley was grown up, had a huge nasty grin on her face which totally said : You can have me whenever you want.

Though Lexie was fighting with nausea she kept searching for her patient file and pretended not to notice Mark and this girl.

But that was worthless. All the thoughts of what they would do together. Of course the girl was awfully beautiful and obviously pretty charming.

Desperatly Lexie tried to fight of all the overhelming feelings of jealousy, but that, of course, didn't work.

''Dr. Grey, did you find Charlaine Corys patient file? It kinda seems to be lost.'' Derek Shepherd asked her. Till that moment Lexie didn't even notice that her sisters husband stood beside her.

''Well, not now, I'll keep searching for it. Maybe a nurse...'' Lexie started to say but with a loud ''What the heck?'' from Derek interrupted her immeiately.

She saw Derek heading over to Marks and the girl.

''Amy!'' he shouted ''What are you doing here? You're just supposed to be in New one wants you here to disturb. But I'm sure I can count on the fact that you will leave soon enough. Just like always!''

''Derek, give her a chance to explain things'' Mark said trying to protect the girl. Well as far as Lexie could tell her name was Amy, and she something she did in her past had to involve Derek and Mark.

''There's nothing she could say that would change things.'' Derek said.

''Oh come on Derek. I even have a present for you. Just give me some chance to make things right. After all I'm still your sister.'' Amy said.

Wow. Dereks sister. What was going on between them? Even though she hated the fact, Lexie had to admit she was courious.

Amy and Derek kept arguing about things Lexie really didn't unerstood anymore, when Mark finally realized Lexie was watching them. He didn't make a move towards her and he also wasn't about to say anything to her.

He just looked at Lexie. And she looked back at him. She nearly forgot the deep blue of his eyes. Their looks said more than a thousand words could ever express.

They coninued that eye starring for about 2 minutes, when Amy grabbed Marks arm and pulled him away. They went towards the stairs and walked upstairs. Lexie, who still watching them, hoped Mark would turn back around and give her one last glance. Just to signalize her she still meant the world to him. And this Amy was just one in a million and she was still the only one in the million.

He didn't.

And once again Lexie's world broke into tiny pieces, she wasn't able to put back together anymore.
