A/N: this chapter is a short one as well but the idea is to portray what happens to both Mark and Zoey after that morning - next chapter will be longer, promise :)

Mark had been lying in the On-Call room for the best part of two hours. His pager had gone off five times, all of which he ignored. He heard the door open and a soft friendly voice called out in the darkness.

"Hey Mark are you in here?"

Mark wanted to ignore it but then told himself to stop being so stupid. "Yeah Lex, I'm here." He called back out. He heard to door shut and the sound of footsteps walk towards the bed where he was lying. His eyes wondered over to where the brunette had stopped walking. What he saw was picture perfect – Lexie Grey was wearing tight fitted light blue denim jeans with a black figure hugging long sleeved sweater. She had her hair down behind her shoulders and looked so gorgeous. Lexie bent down and kissed his forehead. "You look really down, is everything okay?" she asked him, clearly concerned.

Mark nodded. "Yeah, I've just been thinking about a lot of stuff."

"Anything in particular?"

Mark looked at her and shook his head. What could I possibly say to you? I think I've fallen in love with my ex-girlfriend thus I regret going public with you? He thought to himself. He looked at her again and saw the concern in her face. He couldn't remember the last time anyone had given him that look, perhaps because he hadn't given anyone else reason to do so. Nevertheless he liked how worried she was or at least how worried she looked. "Hey don't worry about me. Have you just got here or on your way out?"

"On my way out. I've just finished my shift and I was told to look for you and get back to the chief as soon as I found you but I could take a little bit longer if you wanted me to." She smiled at him. "We don't have to do anything if you don't want to, we could just lie here together."

Mark smiled and moved up the bed to make room for her to join him before lying back down on his back. She bent down and their lips met. The kiss was soft and tender yet filled with passion, something he could never get enough of. However something was missing and he couldn't put his finger on it. Lexie had lain down next to him on her side and kissed him again to show him that whatever he was going through, she would always be there for him. She rested her head on his toned chest and placed her arm over his stomach, which was just as toned. Mark moved his arm over her shoulder and held her close to him. As he lay there playing with the ends of her hair, he thought back to the previous night where he had a completely different girl in his bed.

Mark remained on his side of the bed like he promised, despite wanting to crawl over and hold her tight. He wanted to tell her that he would make everything better; that she should leave that bastard and they can run away together but he knew it wouldn't be appreciated seeing as they had a wall of pillows separating the two of them. He would probably find the situation hilarious if it was happening to anyone but him. On the other side of the bed was a girl who he was crazy about and yet couldn't touch her. He thought it was quite ironic that the person he wanted most didn't want him. He glanced over at the clock that read 03:00. He had to be up in 4 hours but he really didn't want to. He left the chief a message at the hospital asking him to move all his surgeries to after midday – there was no way he would be able to concentrate on anything on just a couple of hours sleep and that was if he was lucky. Looked over the wall of china, he saw Zoey sleep so peacefully and undisturbed. It was like she didn't have any problems at all. Looking over at her, his entire body filled with emotion. His heart felt like it was going to burst. He hated that man, if you can call him that, for hurting Zoey so much. He wondered how long it had gone on for. Derek told him she had been with him for just over two years, since she arrived in Seattle. Had it always been going on or was it a recent thing? He had no idea and didn't know how to address it with Zoey. He really wanted to talk to her about it but he knew it was a sensitive subject matter and knew it was going to take time. He was just getting her trust back so he was going to tread carefully to make sure it remained. He thought back to when she was on his lap, with his arms wrapped round her, protecting her. He remembered how perfect that had felt. He felt whole.

He looked down at Lexie who was falling asleep in his arms. He realised he didn't feel anything that was remotely close to what he felt when he saw Zoey sleeping. When Lexie came in to find him, he realised he was disappointed that it was Lexie. Looking down again, he realised he had the wrong girl in his arms.
