This was going to be a one shot, but clearly, that's not going to happen. It won't be anymore than two or three chapters. But I thought I'd upload as much as I had before I disappeared off to work.

Set in Season 3 at some point. I can't really think where. Possibly around the time of the bet, because that would fit. Only Addison won't be sleeping with Alex.

I own nothing. However, I am going to see Julie Andrews in May and then jetting off to Sardinia in June with two of my best friends! Ooh, how exciting!

Reviews are muchly appreciated. I haven't re-read it, because I don't have the time. So, I apologise profusely for any mistakes in it.


There he was, standing in all his glory, that signature smirk spread right across his face as he flirted with one of the nurses. It was something she was used to, something she knew shouldn't bother her in the slightest, yet it did. It annoyed her so much she hated looking at it, she hated looking at him. It wasn't as though they were anything, they were merely two people who had slept together a lot. Well, there was that, and the fact he was the man she had cheated on her husband with, fallen pregnant with his child and lived with for three months. But they were friends, or something like that.

Just as she was about to turn around, ignore the fact that he was there, he looked over at her, the smirk turning into a genuine smile, something she knew that no one really saw coming from the man. She wasn't going to let him get the best of her, she couldn't let that happen, because where would she end up if she done that, yet again? Instead, she forced a smile back before turning around and making her way down the hallway in completely the opposite direction. She could try and find somewhere to hide out, somewhere that he wouldn't find her.

It was just as she was about to open the door to one of the on-call rooms that she felt his hand on her arm, stopping her from going anywhere. "What?" Addison questioned as she turned around to look at him and she instantly felt guilty for just walking off.

"Are you alright?" Mark questioned softly as he moved his hand from her arm, his eyes remaining on hers.

"I'm fine, Mark." Addison breathed, rolling her eyes at his question. It was the reaction she gave most people when they asked her if she was alright, especially Derek and Mark.

"Right, you're fine." Mark scoffed, it was his turn for the eye roll this time before turning around and leaving Addison to do whatever it was she planned on doing. Addison may she she was 'fine', but he knew otherwise, he knew the woman, he knew that she felt just as crap as he did, they just had completely different ways of showing it. "You're always fine," he mumbled to himself as he pushed open the door to one of the stairwells. He could take the elevator, but the stairs felt much more appealing that being stuck in a confined space with a bunch of people he wasn't too fond of.

As he got to the bottom step, he felt his cell phone vibrate in his pocket twice, a text message or something. He pulled it out of his pocket and went onto messages, seeing Addison's name first. I'm sorry. I just need to be alone. Again, Mark scoffed as he put it back in his pocket choosing not to reply to the text. She always needed to be alone, the one person who craved being around other people so much apparently needed to be alone just as much.

That was at 11:18am that he got the text and he didn't see or hear from the red head for the rest of the day, he didn't even go looking for her, or look on the board to see what surgeries she had. Because she wanted to be alone, she could be alone.

By just after seven, it was time for Mark to get out of the hospital and head back to his hotel. Most nights, he'd head over to Joe's or somewhere for a few drinks, but this time, he wasn't in the mood. He wasn't in the mood to be surrounded by people who were content with their lives, who weren't pining over a red head they longed to have look at them for more than just a few seconds. The drive back to the hotel didn't take long, in all honesty, if he wanted to, he could have walked it. But driving was easier and a lot warmer too.

Mark handed his keys to the young man who barely looked old enough to ride a push bike, let alone drive Mark's car, with a few words about not scratching the paintwork, before he made his way towards the elevators but opting for the stairs once more. This time, he took them two at a time, occasionally three, rather than the slow walk he'd done at the hospital throughout the day.

When he got to his floor, he pulled out his wallet and took out his key card only to see a figure sitting further down the hallway. As soon as he noticed who it was, he let out a sigh and pushed his wallet back in his pocket. "It's unlike you to sit in hallways like this." He mumbled as he held out his hand towards her to help her up.

"You've been avoiding me since this morning." Addison replied, looking at him as he opened the door to his room and held it for her.

"You wanted to be alone." Mark stated, letting the door slam behind him as he proceeded to kick off his shoes and take off his leather jacket. "I was doing as you wanted."

Addison turned to face him, her eyes following his every move as he poured himself a glass of scotch, glancing up at her and pouring one for Addison after she gave a small nod of her head. "You never normally do."

"Well, things change." Mark muttered as he handed her the drink before downing his own and pouring himself another one. He knew Addison hated the stuff, so he wasn't sure why she had agreed to have some, but it meant he got her company for a little while longer.

"I guess." Addison shrugged before taking a small sip of the amber liquid, pulling a face of disgust as she done so.

"Why are you here?"

Addison looked up from the glass of scotch, a little stunned by Mark's tone of voice. She struggled to answer his question, it was a simple question, yet the answer seemed so complicated. "I don't know." Those were the words Addison opted for, only she did know, she knew exactly why she was there. It wasn't because she hadn't had sex in almost six weeks and that Mark was the only person who knew how to please her in a way no one else did. (Maybe that was a small factor in it.) It was because she felt guilty about how she had been with him lately. It was because she longed to be around him again, even if they just sat there in silence. It was because she missed him.

Mark rolled his eyes as he walked over to the sofa in the room and sat down, putting his feet up on the coffee table as he grabbed the television remote and turned it on. He knew Addison would remain where she was unless he said something to her, it was who she was. "Sit down, would you. Do something."

Watching him, she knew she needed to talk to him, she needed to say what was going through her mind and apologise to Mark for being such a bitch lately. Addison walked over to the sofa and placed her glass down on the coffee table, before removing both her shoes and her coat and sitting down on the sofa. She wasn't close to Mark, but she wasn't right at the opposite end to him.

The two remained sitting on the sofa in silence, watching whatever crap Mark had chosen to watch, it wasn't long before Addison felt her eyes drooping. If she was going to fall asleep, she wanted to be more comfortable than she was then. Moving on the sofa, Addison laid down and let her head rest on Mark's lap, still looking towards the television and not making sure that it was alright. She didn't care, she was comfortable.

As he watched Addison move so that her head was resting on his lap, the man couldn't help but smile to himself. She didn't want to be alone, otherwise she would have already left. Mark placed his hand on her arm, brushing his thumb gently over it as he watched television, knowing full well that the red head wasn't paying the slightest bit of attention to it.

What only felt like a few minutes later, Addison was awoken to the sound of someone knocking at the door and she slowly opened her eyes and looked up at Mark who was smiling down at her. "How long have I been asleep?"

"A couple of hours. Mind moving while I answer the door?"

Addison moved so that Mark could stand up, before laying back down on the sofa, but she couldn't get as comfortable as she had been, she needed Mark there. Even though he'd simply been a pillow, it was been the best nap she'd had in a long time. The red head lay there and watched as Mark held the door open for the young boy delivering room service, then handing him a tip which would have been way too much no doubt. "You got food." Addison said softly, feeling slightly hopeful that there was something she'd eat on the tray.

"I got us food, yeah." Mark shrugged as though it was no big deal, because it wasn't, to him it wasn't a big deal at all. Picking up the tray, he took it over to the coffee table near the sofa and pushed the table closer to Addison before going and grabbing a couple of sweatshirts out of the wardrobe and throwing one to Addison. "Before you complain that this room is cold, even though it's not." He knew what she was like, she'd wake up from a nap, be fine for about ten minutes and then start to shiver.

Addison looked up at him gratefully and pulled the sweatshirt over her head, waiting for Mark to join her again on the sofa before she moved closer to him once again. "Are you sure you don't mind if I have some of it?"

"I know I eat a lot, Red. But I'm gonna need some help with all of this." Mark replied, placing his hand on Addison's thigh as he lifted the covers from the trays and placed them down on the floor.

Addison linked her arm through Mark's and leant against him a little more as she looked at what food he'd ordered. He was right, he would need help eating it. Even though she wouldn't eat much, there wasn't a chance Mark could eat all of what he had ordered to himself. "Thank you."

"I couldn't have you starve, could I?" He shrugged before picking up the plate with the pizza on and placing it on his lap. "Want some?"

The two went back to their silence as they ate, Addison finishing most of the Strawberry Cheesecake before even offering any to Mark, who simply stated that he'd got it for her anyway. It was little things like that which Addison loved, how he would think about the things she liked when he was ordering food, even though there was the possibilty that she might not want anything at all, or she could have yelled at him for letting her sleep for so long.

Once all the plates were almost empty, Mark got up and put the tray outside of the door and left it there for someone to pick it up. Walking back into the room, he looked at Addison sitting on the sofa watching whatever it was he'd been apparently watching for the past two hours and he let out a soft sigh. He had no idea why she was there, what the Hell she wanted, but he wasn't going to ask her to leave while he got some sleep. "Why are you here, Addison?" Mark asked as he sat back down beside her, looking at Addison rather than the television.

Slowly and reluctantly, Addison brought her gaze away from the television and up to Mark who was sitting there waiting for an answer, they both knew he wasn't going to be getting easily. "Like I said, I don't know."

"You never fucking know. You never fucking want to be around anyone. You always want to be alone. This is you, Addison, the woman who hates being without someone for company, the woman who happily stayed with me for three months after her husband decided to move across the fucking country."

Addison fell silent, and she cautiously reached for Mark's hand, hoping that he wouldn't pull it away. "Who was that you were flirting with today? She seemed nice."

"What does it fucking matter to you?" He hated getting angry at Addison, absolutely loathed it, but he couldn't handle it anymore. He wanted this woman so much, he wanted to actually get a chance at a relationship with the woman and she wasn't giving him anything back.

He hadn't pulled his hand away, he may have practically yelled at her, but his hand was still laced with hers. Something which Addison knew was a good sign. "I guess I've got used to being alone," she replied to his earlier statement.

"That's your choice."

"You don't exactly help me choose otherwise."

Mark didn't have the slightest clue where this was going, there was even a part of him that didn't want to know where it was going. "What's that meant to mean?"

"You, sleeping with everyone. You say that you want to be with me, Mark. But then you go and sleep with anyone and everyone you possibly can."

"And you help the situation, do you? Asking to be alone, telling me that I'm lying and I don't give a shit about you? You don't get to choose how I feel, alright? That's down to me. If I say that I love you, it's because I do. It's because I'd do anything for you. I've done everything you've asked me, other than staying in New York. Because I won't, not while you're out here as fucking miserable as you are, I won't go back. If you want to be miserable and feel sorry for yourself out here, then let me do the same." Pulling his hand from her grip, Mark got up from the sofa and made his way to the bathroom, stopping as he reached the door. "As for me sleeping with anyone and everyone, I haven't had sex with anyone since the last time we done it."
