A/N: The timeline in this fic is a little AU. It will have things that happened in the past happening alongside things that are much more recent developments. It's basically my take on what I wish would have happened with Addison and Mark's baby, Ella, and how she would fit into his family. The main ships will be Maddison and Calzona. If there are any questions (that I can answer without giving way plot), let me know. I hope you enjoy it! I welcome any reviews.

She knew they'd be coming up the stairs soon. They always did. It happened like clockwork. She and Tate would have a fight, she'd get upset, and her whole family would come to the rescue.

First they'd send Charlie in to try and make her laugh. Though he was a funny kid, they should have learned by now that that never worked. At a time when a sixteen-year-old hates all boys, her twelve-year-old brother is definitely not going to be the one who changes her mind on that.

But still, Charlie walked in. "You can go away," she told him. "And you can keep Mom out. And Dad."

"He's at Sofia's anyways."

"Oh."

Her mom walked in. "Charlie, I made cookies."

"You can't bake. I should've gone to Callie's with Dad. Arizona makes better cookies."

"Thanks a lot," she replied.

"I know you're just trying to get rid of me," he told her.

"Then go," she laughed.

"Fine." With that, Charlie left.

Her mom began stroking her long blond hair as she lay with her face buried in the pillow. "So, what was it this time?"

"Oh, like you'd get it."

"Try me," she said.

"You've never had issues with boys."

She laughed. "Uncle Derek, your father..."

"But those worked out!"

"But there was a time when I didn't think they would," she said.

"I know. I know. I've heard this story so many times."

"But it's a good one."

"Well, duh. It's about me."

She never realized how much stuff she had until she loaded it into the car that afternoon. Her doctor had forbidden her to fly – actually to travel at all this late into the pregnancy – but she had to get out of there. The baby was her motivation.

She didn't know what she'd say when she arrived, but Seattle Grace-Mercy West was programmed into her GPS and she was headed there – ready or not.

She remembered wondering who would be harder to face – Derek or Mark. She really wasn't looking forward to seeing either of them, but she had decided that Elizabeth deserved at least a shot at knowing her father.

When she finally pulled into the parking lot she took a deep breath. She could do this. Give the divorce papers to Derek and beg Mark for a second chance.

She's Addison Adrienne Forbes Montgomery-Shepherd. Up until this moment, she had never even thought about begging for anything. Yeah, she had begged Derek to stay, but that wasn't totally sincere since she was already falling for his best friend. This true begging would be a first. She rubbed her big belly and felt her daughter kick. Baby Elizabeth was already her biggest fan.

She got out of the car and walked up to the hospital. She turned around when she heard the sound of someone being sick behind her. "You okay?"

"Yeah, yeah," the woman – a doctor there - said. "Pregnant."

"Oh." She smiled. "It gets better. Congratulations."

"Thanks. You too."

"Thanks," she said.

With that, she turned and walked into the hospital. Everything in her wanted to turn back and just head back to New York, but she couldn't. She knew this was the best thing to do.

"Has anybody seen Torres?" she heard him ask a group of nurses.

They all pointed toward the door.

As he walked, their eyes met. "Addie," he said, his eyes instantly landing on her rounded belly. "You're..."

"Yes, I am." She forced a smile.

"Could it be Derek's? Please say it could be Derek's..."
