You met your match when you met me
I know that you will disagree it's crazy
But opposites attract you'll see
And I won't let you get away so easy

The love you save may be your own
Can't fight this feeling, aren't you tired of being alone
You won't admit it but you know it's true
It's not a secret how I feel when I stand next to you

Causing a commotion, Madonna

Chapter 1 - Causing a Commotion

Addison was awoken from sleep by the persistent beeping from a pager. She reached down and flipped open the pager, stopping the monotonous noise immediately. The last remnants of sleep were shaken away when she read the message from one of the nurses. One of the preemies in the NICU was crashing. She cursed quietly under her breath then set out for the NICU at as faster pace as her stiletto heels would allow.

She had been hoping that this week would be quieter than the last but so far it had been worse. She squeezed through the elevator doors just as they were about to close and jabbed the button for the right floor more forcefully than intended.

"Rough night?" A voice asked from directly behind her. Addison jumped and barely contained a squeak of surprise. She turned quickly to locate the voice that has spoken to her.

"Mark, I didn't see you," She replied, resigned to the fact she could not escape the conversation.

"Clearly you were too busy attempting to break the elevator buttons to notice me. Care to share what's on your mind? Maybe I could help."

"You can't help me," she replied through gritted teeth. She really didn't want to deal with this right now.

"Why not? I certainly helped you the other night," he smirked at her.

"No Mark. You didn't help me. I'm sorry, I really am. I shouldn't have come to you the other night, it was weak and it's not fair to you or me. I can't keep putting myself through this." She took a deep breath and glanced at the numbers as they lit up one by one above the door. She silently willed the elevator to move faster so she could escape from him.

"What are you talking about Addie? There's no reason for you to be sorry, we don't have to feel guilty because we aren't doing anything wrong."

"Yes we are Mark, everything about this is wrong. The other night shouldn't have happened. Plain and simple. I was upset so I fell back in to what I knew, but that's not going to happen again. I'm sorry." She gave him one last look and then jumped off the elevator before the doors had even fully opened.

She arrived at Sarah Thompson's room seconds later and began working on her straight away. She calmed down as she worked, this was familiar to her and she knew she could do this. Sarah had been born premature 3 days earlier, Addison had performed the c-section and had been monitoring her ever since. She let out a breath she didn't know she had been holding when she saw the babies BP stabilise again.

"Ok. She needs to be monitored very closely. Page Alex Karev for me," She said to the nurse who had been helping her. Addison leaned against the glass box of the incubator and closed her eyes briefly. She was exhausted and allowed herself a brief moments thought.

The last few weeks had been chaotic to say the least. She didn't know what was going on with her lately but it seemed that she was making one mistake after another. She had kissed Karev and then slept with Mark, behaviour which she wasn't proud of. She couldn't explain why she had done it, he was just Mark and she was lonely so she had sought comfort in him.

Alex was a different story. She didn't know when they had crossed the line from being co-workers to…more than that. It was unexpected but not necessarily unwelcome. She felt something for him and she had been sure that he had felt something for her. But then he had said that he kissed her back because she was his boss and that he wasn't interested. Either he was an extremely good liar or she had misread the signals and he really wasn't interested in her.

She opened her eyes at the sound of footsteps approaching the room. Alex Karev entered with a frown on his face but it seemed to soften slightly when he saw her. Or maybe that was just her mind playing tricks on her again.

"You paged me, Dr.Montgomery?" He asked as he made his way over to the incubator. His frown deepened slightly as he looked at her, and she was sure she saw concern in his eyes. "Dr.Montgomery? Are you ok? You really aren't looking too good" He questioned.

Addison shook herself from her thoughts and plastered a smile on to her face. "I'm fine Karev, don't worry about it. The baby crashed a while ago, she seems stable again now but I want you to check on her every half an hour and page me if there's any change"

Alex nodded his head but continued to stare at her the concern now clearly evident on his face. "Ok, maybe you should get some rest while I monitor her." He replied.

"What's with the sudden concern for my wellbeing, Karev? I've never known you to care before." She said in a tired voice.

"I do care. Maybe I don't always show it. But I care." He took a step closer to her and stared in to her eyes.

Addison froze at his words and stared back with equal intensity. She got lost in his eyes so often these days that this was not an unusual experience for her. Her breath quickened as he took another step towards her, but then he stopped. Alex gazed at her drinking in everything about her. He saw the tiredness in her eyes and the tension in her jaw. He saw the way her smile slipped off her face as quickly as it had appeared. He took another step towards her and reached a hand up to her face tentatively.

Addison let out a soft sigh as she felt his hand on her cheek and couldn't help but lean in to his touch. The implication was not lost on her. It was the exact same action that she had taken right before she kissed him at Joes. He took another step so that his body was almost touching hers and stared down at her intently. She found herself leaning in to him as he leaned towards her. Their lips were millimetres from each other and she could feel his breath on her face.

Addison wasn't sure who moved the last few millimetres that separated them, maybe they both moved at once. The next second his lips were on hers and she melted her body against his. One of his hands tangled itself in her hair while the other trailed lightly down her arm and gripped her waist. She ran her hand up his chest and parted her lips under his.

BEEP. Addison jumped backwards and groped for her pager again with unsteady fingers and read the message. She glanced at Alex to find that he looked equally as shaken.

"Erm, that's the ER. I have to go." She managed to stutter out.

"Yeah, I should check on some of the other patients. But I'll monitor Sarah every 30 minutes like you asked and page you if anything changes." He said.

"Ok, thanks Karev. I better go." Addison said as she backed out of the room.

Alex watched her leave and then glanced down at the baby beside him. He couldn't get Addison out of his head. Part of what he had said to her the other day had been true, he really didn't want to be just another intern sleeping with an attending. But the rest, well saying that he wasn't interested in her couldn't have been further from the truth. He never would have believed that she could be interested in him, but then she had kissed him. He had dared to hope that she might actually see something in him but then she spent the entire week afterwards avoiding him. Clearly she regretted the kiss. So he had reacted the only way he knew how and built up his walls again.

Alex gathered up the charts and headed back to nurses station to drop them off. He had other patients to check on as well as checking on the preemie every 30 minutes. He had a feeling that he wouldn't be able to concentrate at all today the only thing he could think about was Addison.

Addison hurried out of the elevator and headed towards the hospital doors relieved that she had made it through the day. She walked out in to the parking lot and felt her body relax slightly as she left the confines of the hospital. She looked up when she heard voices and saw Derek and Meredith walking hand in hand across the parking lot. Her stomach churned slightly at the sight of her ex husband so carefree, as if he had been divorced years and not weeks. Addison had given up on reconciliation with Derek and she truly was moving on from him. But it still hurt to watch the man she had loved for so long discard her without a second thought.

She almost ran towards the car and hopped in resting her head against the headrest and letting out a weary sigh. Every time she closed her eyes she saw Alex's face in her mind, felt his breath on her lips. She smiled softly to herself remembering his revelation that he did care about her and ran a finger over her lips feeling them tingling at the thought of their kiss. She opened her eyes and mentally shook herself from her daydream.

"Get a grip Addison, he's your intern," she muttered to herself as she put the car in gear. She took one last glance at the hospital and then drove away, glad to finally be going home after a long day.
