Hope you liked the first chapter. It really was just an intro, everything will start going in this chapter. I really was hoping for more reviews though, I may have to stop writing if I don't get more. Yes, that was a threat. I do not own Grey's Anatomy.

Unbelievable

"Oh…my…gosh," Christy repeated herself. She couldn't bring herself to say anymore, she was just too shocked that this person was standing in her doorway. She had hoped she would never have to see him ever again, and a few months later was way too soon.

Addison listened from the kitchen as Christy said the same thing again, starting to worry her. She decided to check who was at the door and if her daughter was alright. She rounded the corner just as the man at the door finally spoke to Christy, giving Addison a sinking feeling in her stomach. "You miss me kiddo?"

"Mark," Addison stated, causing him to move his gaze from Christy to her.

"Addison!"

"What are you doing here Mark?"

"I should be asking you the same thing, you came here after Derek and you aren't even with him anymore."

"I asked you Mark, what are you doing here?" Addison repeated herself, even though she already knew why.

"I miss you and you kiddo," he said, turning and ruffling Christy's hair, only to have her quickly shove his hand away. "Your marriage is over Addison, please come home."

"Mark you should go," Addison said, pointing to the door.

"Not until you tell me that you are coming home."

"She said go!" Christy told him, pushing him out the door, and then closing and locking it. She turned around to stare at her mother with a look on her face that showed she was upset and angry; a face that very much resembled Derek's when he was upset. This just made it so much harder to cope with. She felt like she was staring at Derek.

"Honey…"

"No…he knows exactly where we live and the only way he would know that is if you told him!" She shouted, before running up the stairs and slamming her bedroom door shut.

Christy lay down on her bed but before long, jumped up and started pacing, a trait she had picked up from Derek as well. They were doing so well, both her parents, and she was improving her relationship with Addison, and now Mark had to show up and put a stop to it. Christy was almost sure that her mother had called him; they weren't even in the phone book yet and there was nobody else that would've told him where they lived. This was so frustrating, her family was changing all around her, why couldn't things just go back to the way they used to be when she was little, she thought. Christy turned on her music to try and push these thoughts out of her mind and before long she laid down on her bed and fell asleep.

It had been almost three hours now since Mark had shown up at her door and Addison had managed to down way more alcohol than she needed but she just couldn't bring herself to stop. The man who had broke up her marriage, who her daughter hated and never wanted to see again had showed up at their door and expected everything to be great between them. Addison found herself almost feeling sorry for him, which she definitely shouldn't be in this case, that wasn't right.

Wanting to get these thoughts out of her head Addison walked up the stairs to check on Christy, when she opened the door she saw her fast asleep on her bed, still in her clothes, with her radio and lights still on. Not wanting to wake her up she pulled a spare blanket out of the closet and draped it over top of her, shut off her music and lights and just before leaving the room, whispered a faint, "I'm sorry Sweetie."

Addison walked down the stairs again, sat down in the living room and picked up the cordless phone. She debated whether to do it or not but found her fingers deciding for her, dialling a familiar cell number. The phone rang once and then someone answered; "Hello…" There was no answer so he tried again; "Hello…Addie…"

"Mark…"

Christy woke up to see her clock flashing 10:30 and it took her a minute to figure out why she was still in her clothes, but then all the memories of the evening came back to her. She realized she had missed dinner so she decided to get a snack, as she walked down stairs she could faintly hear her mother's voice coming from the living room and figured she must be on the phone. But as she got closer, she realized that there was someone talking back.

She entered the dimly lit living room and the scene almost made her sick. There were two empty bottles of wine on the table, along with two empty wine glasses. Her mother sat on the couch with Mark, her hands around his neck, his up the front of her shirt and there lips locked together in a very passionate kiss. She stood there for a second in a complete state of shock, unable to find the right words to say. Finally the right one came to her; "unbelievable!"

Mark and Addison were startled apart and looked up to see Christy run out of the room, and this time instead of going up to her bedroom and slamming the door, she ran down the steps and slammed the front door. "I better go," Mark said after they sat in silence for a moment, both trying to process what had just happened.

"I have to go find my daughter," Addison replied, not caring one bit what Mark was doing, just worried about her little girl being out in the streets of Seattle in the middle of the night.

The second Christy left the house she ran, all she could do was run, she was out of breath but that didn't stop her, she had to get away, and every step she took it still wasn't far enough. Finally after getting almost 3 blocks away she forced herself to stop, passing out wouldn't do her any good. When she stopped, the reality set in and she laid down on the grass beside her and cried, her family was breaking.

Addison followed the route she was sure Christy would take, it was the quickest way to get to Meredith's house, which was where Derek was and Addison knew that he was the only person Christy wanted right now. He always had hte ability to comfort her, she definitely was a daddy's girl. Seeing her daughter in the grass on the side of the road Addison pulled over, shut the car off and stepped out. "Christy…" But she got no answer, "Christy…Honey, I am so sorry." She still didn't get an answer. "I know where you want to go babe, and if you get in the car I promise to take you there right now."

"I'm not going anywhere with you, I can walk you know," Christy replied nastily.

"Of course…But it's 11:00 and it's dark and I would never be able to forgive myself if something happened to you, so just let me drive you to Meredith's so I know that you're safe." Christy didn't say anything just got up and got into the backseat of the car so that she didn't have to be near her mother. Addison got in the car as well and pulled out on to the street, she rounded the corner and looked in her rear-view mirror at her crying daughter. Her eyes lingered for a second too long and Christy screamed; "Look out!" Breaks from both cars screeched in an attempt to avoid the collision but it was too late, a pick up truck smashed into the driver side of Addison's car and they were both knocked out.

Bet you didn't see that one coming huh?
