Addison lay in there bed staring at the ceiling. She had a thought as to what Derek wanted to tell her. She had seen the look passed between him and Meredith at the end of the prom. And the truth hit her like earlier, when she has asked Meredith what was going on between her and Derek and she had said she was involved with the vet at which point Addison had realized that Derek was jealous; tonight she knew where he had been, when he had said that he went to check on a patient. And then the way that he was acting after he came back to her, she knew what he had done, and who he had done it with.

I'm through repaying my debt to society, and to Derek she thought.

Then Addison started to reminisce over the happier times. The day they got married, the vacations that they would take, even the small things like holding hands in the hospital, or kissing in the elevators. And then there was the day that she had found out that she was pregnant. She remembered it like yesterday; she had woke up and had tried to get out of bed, but had gotten so dizzy she had barely made it to the bathroom before she threw up.

It didn't take her but a few minutes to diagnose herself, but she wanted to be sure before she told Derek. It was her rare day off, but Addison headed into the hospital anyway. She was careful to avoid anywhere that Derek might be, and headed to a close friend of hers, who happened to be one of the best OB/GYN's in the hospital. A quick blood test confirmed what Addison already suspected, she was so excited that she couldn't wait till later to tell Derek, so she had set off to find him.

And she had found him; he was in the middle of a surgery, so she watched from the gallery. She could see the surprise in his eyes when he first noticed her sitting there, because she tended to avoid the hospital like the plague on her days off. She was waiting out in the hallway when he had finished scrubbing out.

"Hey babe, what are you doing here?" he had asked, giving her quick kiss as they started to walk towards the attending locker room . "Well, I got sick this morning and," Addison tried to finish but Derek cut her off. "Sick, why didn't you call me?" Derek questioned. "What would you have done Derek, held my hair while I threw up?" Addison shot back. Derek grabbed her arm to stop her from walking, "Addison, what's up, you never throw up, even when you're completely drunk." By now Derek was starting to get worried, but then Addison started to smile at him and said, "I threw up, because I'm pregnant, Dad." Then Derek had hugged her, and said, "I'm going to be a dad. How did this happen? I mean I know how it happened but, wow!" He then picked her up and spun her around a time or two, the whole time grinning from ear to ear.

The whole time she was pregnant, Derek had been so attentive, he hadn't even wanted her to take the groceries out of her car, for fear that they would be too heavy. Addison finally had to sit him down and tell him that she was pregnant, not helpless, and she hoped he would be that attentive when they're daughter was born. That started a huge controversy because the whole time during her pregnancy Derek told her she was having a boy, which she simply would not accept. "I am having a girl," she had told him, "because I need somebody to go shopping with me since my dear, devoted husband won't."

Derek had then almost missed the birth of their daughter because of a surgery. Addison had paged him for almost and hour before he had finally called her. "Hey Derek, what ARE you doing?" she had snapped at him. "I just got out of surgery, why, are you alright?" he questioned. "Well, I'm not going to be in another few minutes, because you will have missed the birth of your child, and then I will kill you, so why don't you hightail it up here NOW!" Derek was already running up the stairs when Addison hung up on him. Around 15 minutes later, their daughter, Hadley Montgomery Shepherd, was born. Addison had never seen Derek look so happy, especially as he did when he walked up and down the halls of the hospital showing off his little girl.

Addison drifted off to sleep still thinking about her daughter. She would deal with everything else tomorrow, but tonight she was picturing Hadley's first words, her first steps, and the first time she had taken her shopping and how all of the sales people commented on what a beautiful baby she was.
