So, as always I have been terrible at updating. My life is so busy it's crazy. But...here is the next chapter (sorry for leaving you on a cliff hanger last time.)

Just a note: this is not orginally where I planned to go with this story, but I got the idea in my head and it wouldn't go away. I have done research but only know as much as the internet allows me- I am no doctor! I know Lucas is young for what is wrong with him- but my research said it is rare for a child to get sick in this way, but can happen.

Chapter Four

Derek was on a date with his wife, his wife who he doesn't see very often, when he got the phone call. Normally, he ignores calls when he is with her but when he saw Addison's name flash up on the screen he knew something was wrong. She never called him. Derek tried to ignore the look of annoyance on his wife's face as he answered.

"Addison?" He answered questioningly.

"Derek! You have to help…you have to help him! I-I-I need your help." Addison's voice was quick and panicked, and he could barely make sense of what she was saying.

"Addison- slow down." He got up from the kitchen table and moved into the living room, in an attempt to get a little privacy. "What's wrong?"

"It's Lucas." She sobbed.

As much as Richard Webber loved being the Chief at Seattle Grace hospital, he hated the drama. He had found out over the years, that surgery and sex was not a good combination. In fact- if he could find a way to stop his employees from intermingling he would have started insisting on it years ago. Above it all- he hated the rumors. No matter how much he might enjoy reading Nurse Debbie's blog on a slow day. When he had woken up that morning, he had known it was not going to be one of those days. His feeling was confirmed when Derek Shepard made his way into his office before his shift had even begun.

"Derek," Richard greeted with confusion in his voice. "You aren't supposed to be here until this afternoon."

"I know Richard," He a folder on the desk and Richard started to look through it. It was full of copies of MRI scans.

"What-"

"They are of a three year old boy with a tumor that is benign. The patient had complained of headaches and nausea, and was taken to hospital after he lost his balance at day-care and hit his head."

"As rare as this is in such a young child, Derek, I don't really see why this is the cause of your apparent panic."

"Read the name on the file, Richard." The older man did as he was told and closed his eyes as he signed in disbelief. "They are on their way. She said they were getting the first plane out of LA this morning. They should be here soon."

"Knowing Addie, she will want this done in a specific way."

"She knows it will be hard to keep people gossiping, but she obviously doesn't want it done around the boy."

"I'll see what I can do." Richard said as Derek left the room. He shook his head. Addison Montgomery was never going to get a break.

Addison sat in Seattle's airport waiting for Pete to return with their bags. He had tried to lighten the mood by saying it had to be the first time she had gone somewhere with only one suitcase, but had failed. The past forty-eight hours had been a blur- she hadn't eaten or slept and she doubted Pete had either.

They sat in silent shock. Charlotte had left them alone after telling them Lucas had a brain tumor. The 3 year old was asleep in his hospital bed unaware of his parents turmoil. After minutes of silence Addison suddenly sat up.

"I have to call Derek."

"What?" Pete asked in disbelief. "We find out our son is sick and the first thing you want to do is call your ex-husband."

"Yes Pete, my ex-husband who also happens to be a Neurosurgeon. Not only a neurosurgeon but the best damn neurosurgeon on the east coast. Possibly in the country." She wiped a tear from her cheek, this was not a time for crying- it was a time for action. There would be plenty of time for tears later.

"Addison- the neurosurgeon here-"

"Is not as good as Derek. Now I don't want anyone else but the best to be cutting our sons head open." She looked at her husband- begging him to understand. He nodded slowly at her. "Okay, I'll make the call and tell Charlotte we will be getting a plane to Seattle first thing tomorrow morning." She kissed his cheek quickly before leaving the room.

She got her cell phone out of her bag and dialed the number she had never been able to forget. It was only when Derek answered that she finally allowed herself to cry.

The news had spread like wildfire. However, after threats from both Bailey and Chief Webber most of the nurses had said they would stay quiet. Bailey walked up to her old interns- who were standing at a nurses station gossiping.

"I didn't even know Satan had a baby! Cristina exclaimed. "The boy is three right, she was here just over three years ago and didn't look pregnant- and hasn't mentioned anything when she's been here since."

"Maybe that's because Dr Montgomery likes to keep her new life private." Bailey interrupted. "The baby is not her biological son- but he is her husband's boy. Obviously the child is three- so doesn't know. If he finds out I will blame you four. Even if it wasn't you I will blame you, and find you and use all my power to make sure you are on rectal exams in the pit for the rest of your lives."

Whilst Bailey knew she could no longer tell them what to do, she was well aware she terrified most people in the hospital. "Also, keep the gossiping to a minimum. Dr Montgomery has had her fair share of the gossip here. And get back to work!"

After Bailey left Cristina turned to Meredith.

"You're being quiet."

"Don't kill me, but I knew she has a kid."

"How did you know? More importantly- why didn't you tell me?"

"Derek knew, and she didn't want everyone here to know. She has no choice now."

It was raining. It didn't surprise Addison, it always rained when she came to Seattle. As Pete brought their rental car to a stop Addison closed her eyes to try and fight back her tears. She had never wanted to bring her family here, especially under circumstances like this. Before getting out of the car, she briefly wondered what would happen as her new world collided with her old one. She got out of the car and got Lucas out of his car seat.

"Mummy- where are we?" She smiled for him, hoping he couldn't pick up on the fact it wasn't real.

"At a hospital, buddy." She met Pete on his side of the car and they walked towards the hospital together.

"Why?"

"Well you know your head is poorly, an old friend of mummy's is going to make it all better." How else was she supposed to explain it to him?

"Forever?" He asked innocently. Addison looked at Pete over Lucas's head.

"Yeah, forever." Pete answered for her.

Addison just wanted it to be Monday again, when everything had been normal. If she had known how her week would turn out, she would never have moved from her bed.

Ok, so what do you think?

I hope you like it. I really wanted Addison and co to end up in Seattle. It will be interesting to see how it all works out.

Prepare for drama to come- and not just with Lucas being sick- I have a whole lot more up my imaginitive sleeve.

Please review- they make me happy!

I promise to update sooner!
