Dont know when I'll get to upload another chapter. please review.

Mark had spent the night in Seattle Grace, knowing he would be unable to sleep if he went home. So he worked on extra paperwork and did some research until finally he fell asleep in the couch in his office. When he woke the next morning already he could feel butterflies tumbling around in his stomach. He barely noticed the crick in his neck or the ache in his back from his uncomfortable sleeping position. He cleaned up his office and made his way to the locker room where he took a quick shower. Grabbing a quick breakfast and a strong coffee he set about seeing patients keeping an eye on the time as any minute now Izzie would be coming into work.

And five minutes later there she was. Deep in conversation with George who was telling her something and her response was just to roll her eyes in typical Izzie fashion. Izzie always took Marks breath away but today he was wondering if he would need an oxygen mask just looking at her. She caught his eye and smiled tightly at him as she made her way along the hall with George. Picking up his charts he went to walk towards Izzie when he came face to face with Callie.

"Oh my God Mark I need you and a coffee right now." She said as she grabbed him and pulled him towards the coffee cart. Mark attempted to protest but Callie was not listening.

"It's Arizona, it's just moving so fast. She asked me to move in with her." Callie said with her eyes wide to dramatise the situation. "I don't know what to say, like it's soon right, and like when I do things fast it goes wrong like with George and Erica but I dunno what to do, cos maybe fast is good. What do I do?"

"Stop it right now; stop looking at me with those eyes. Seriously you're coming to me looking for relationship advice?"

"Yes because you had it, you had the great relationship that was the stuff of movies and you blew it. And I want that with Arizona." She responded directly.

"Well Izzie and I moved in together soon after we became a couple." He offered "The thing about relationships is you just gotta do what you think is right and have no regrets." He said realizing he had many regrets.

Callie smiled at him and squeezed his hand. She knew he never got over Izzie. "Thanks." She replied, "You've not been much help but still."

"Do you think I blew it with Izzie?" he asked.

"Yes Mark, I think you did. You both did."

Izzie should have been an actress. She had even surprised herself with how calm she was acting today despite the fact that she was totally panicked and jumpy. In typical Seattle Grace fashion the day she wanted to do as little work as possible turned into chaos. First she had a celebrity patient who had flown in from New York especially to have Izzie do her latest breast enhancement and facelift. Following that there was a fire in a local school which lead to her being pulled in on numerous surgeries and being paged to all sections of the hospital. Izzie had worked with Mark throughout the day but had barely gotten a chance to say anything to him relating to their baby. They made some small talk in the OR keeping up appearances for the nurses and other doctors in the room.

At 8:00 that night Izzie and Mark were standing at the large sink scrubbing out.

"God that was like the worst day ever." Izzie commented. She hated working on children because in plastics she only ever worked on children when a fire, car crash or something else awful had happened to them. Usually when she would be the first asses them and they would be in excruciating pain and Izzie could not bear the screams she had often heard in the hospital over the years.

"Yeah it sure was busy." Mark agreed.

"I have another surgery scheduled now so I better go." Izzie said as she dried off her hands and made her way to the door.

"Iz, will you come over to mine when you get off work? We need to talk." He said as Izzie's pager went off.

"Crap, 911. Yeah I don't know when I'll be finished. It will probably be late, is that ok?" She asked as she made her way to the door.

"Yeah, see you later."

Two hours later Izzie was leaving Seattle Grace. She had just lost her patient who was a six year old girl. Her body ached and she really just wanted to go to bed but she had to face Mark. She made her way to the car hoping that she would not have such a busy day ever again. As she drove the familiar route to the apartment she had shared with Mark years ago she could not help but feel overcome with emotion. She had no idea how the next few hours with Mark would go. How they would work this out. As she parked her car she could feel her nerves rising even further.

She entered the front door to her old apartment block with the key she had never given back. They had lived in a mansion that had been converted into a number of large fancy apartments. Izzie had fallen in love with the place when Mark had showed it to her and he surprised her even further when he presented her with a key and told her that she would be moving in with him. It was never up for discussion she was to live with him end of story. She had offered a million times to pay rent or contribute to the mortgage but he did not have a mortgage. He had sold his pent house in New York which was worth a lot more than this apartment at the time.

She knocked nervously on the door suddenly feeling scared about entering his apartment, no longer their apartment. Behind the door were rooms that held so many memories for her. Taking a deep breath she plastered on a smile as the door opened.

"Oh my God, Izzie." Gloria's shrill voice rang out. "Mark is going to propose to me." She blurted out.

"What?" Izzie gasped as her mind raced. Where was Mark?

"Yeah I just popped by and I found the engagement ring in the drawer beside his bed." She cried in excitement.

"Wow, that's great, congratulations." Izzie said quickly as she felt tears gather on her eye lashes. "Well, actually I better go." She said as she backed away from Gloria.

"Did you come here for something? Are you sure you won't come in and have a glass of wine? I'm sure Mark will be back soon, I'm leaving now anyway, I don't want him to know I came across his little surprise." Gloria cooed making Izzie's stomach churn.

"Oh it was just something for work. It's not important. Bye." Izzie said over her shoulder as she ran down the stairs and out onto the street. She quickly got into her car as tears streamed down her face. Needing to get away from the familiar street she wiped her eyes staining her hands and cheeks with mascara as she drove to Alex's place praying he would be home.
