A/N: Well, I'm always in an Addek mood but never really wrote a story about them. So here it is! Finally!
By the way, this is set sometime around season 3, after all the prom drama.

Derek couldn't help but overhear the nurses' hushed conversation on the other side of the counter. He knows that he shouldn't eavesdrop, but he remembered that the hospital runs on gossip anyways so he thought that listening to those two nurses wouldn't hurt. He pretended to look at the chart in front of him as if it was the most interesting thing in the world as he sneaked up some glances to the two people on the other side.

"You know who's the cutest baby in the nursery?"

"Baby Johnson, duh! His hair is so blond and his eyes are bluish-green."

"Ha-ha! You are so wrong! It's the Shepherds' baby that's so adorable! Her cheeks are so rosy and she smiled at me earlier! She is just so precious!"

"Well, Rosebud…"

"Rosebud?"

"Yeah, you said her cheeks are rosy. So that's what I'm calling her from now on."

"She has a name, you know."

"She does, but I don't know. And I think that you don't either."

"Right."

"Well, I believe that Rosebud will be a heartbreaker like her mother. In a good sense though. Dr. Montgomery-Shep… well, Montgomery now, is quite a looker."

"Don't forget about Dr. Shepherd."

"Sure. But I think that the only thing she got from him is his hair."

"True."

As the two nurses left, a part of him knew that he had to see his own daughter for himself.

Derek slowly made his way to the nursery to only find a nurse feeding one of the babies in one of the cribs. He approached her and asked which one was Baby Montgomery-Shepherd, and he saw the nurse stiffen and hesitantly showed him the way. He thanked the nurse as she went out the door to give him a little privacy. He approached the crib that held his little girl, who was only a few hours old. When he saw the card, his heart dropped when he only saw Baby Montgomery written on it instead of Montgomery-Shepherd, but he decided to ignore it. Derek moved closer and touched the top of her head, which had strands of dark hair that promised to curl as she grows older. He saw her open her eyes for a minute, probably sensing his touch, revealing stunning, bright blue orbs. It's been a while since he's fallen in love at first sight. It's not infatuation, but absolute love.

"Hello baby girl," he started, feeling tears pricking his eyes. "I know that I'm not supposed to be here. That I don't have the right to be here anymore with you, but I just… I really don't know why I'm here. I just had to see you for myself, to see what I missed and what I'm going to miss. I'm sorry, baby. I'm sorry for treating your mom that way."

He smiled when he heard her stirring. And that's when the thoughts started flooding his mind. In the early years of their marriage, he had imagined them having the perfect family. With him, Addison, a little boy and a little girl with their best features. But now, he knows that he had messed up and this illusion of having the perfect family had long been taken away from him. Because he and Addison are officially divorced and he couldn't think of a way to get back in her life after all the hardships he had caused her.

Derek fell out of his reverie when the door to the nursery opened. That's when he saw Addison. He hasn't seen her since… well, since she was still pregnant with their baby. He tried to smile at her but it was only reciprocated with a stern gaze from her.

"What are you doing here, Derek?" she said, approaching their newborn.

"I… uh… I just wanted to…"

"Wanted to what?"

"I just heard them talking about her. Calling her 'Rosebud' and all and…"

Addison looked at him quizzically. "Hmm."

"Uh, Addie?"

"What?" she turned to him.

"What's her name? I just want to know her name," his voice sounded pleading. He just wanted to know his only daughter's name. His daughter whom he resented before she even came to the world.

"Arabella Dionne Montgomery."

"That's… beautiful. It fits her," he again, tried to smile even though his heart ached a little too much. "Thank you."

She only replied with a silent nod but never took her eyes off her daughter, who was slowly waking up. He saw her pick up the little girl and walk over to the rocking chair. He wanted to be with them- hell, he would literally do anything just for that, but he knows that he couldn't. He knows better than to push Addison after everything that happened between them.

He turned to the door and once he was about to leave, he heard Addison say, "Derek!"

"Yeah?"

"Thank you… for bringing her to my life," she smiled softly at him.

He smiled back at her and pushing his luck, moved forward and kissed both of them softly on their foreheads. Again, he went to the door and looked back at them with a smile plastered on his face. At this moment, as she was holding the precious evidence of the love they once shared in her arms, he felt hope. He felt hope about rebuilding the family that he once dreamed about.

A/N: If you're wondering why Derek hasn't seen his daughter, it's because Addison didn't want him in there while she was giving birth. Plus, Dr. Shepherd had another surgery. Go figure. xD Aaaaand, I don't know if this is just going to be a one-shot or...
