A Different Start

Chapter 1:

Meredith walked though the hospital one morning doing her rounds with a bright and shiny smile on her face. One look at her and you knew she had never been happier. She had met Derek only 3 months before and she knew she was in love with him. Everyone knew about their happy little relationship, everyone except her parents. They both worked in the hospital, but they were both too wrapped up in their work to listen to gossip about their daughter and the head of neurology. Then again, even if they did know, they could not say anything about it. In the beginning of Meredith's internship she made them promise that in the walls of the hospital they were to act like they didn't know her. It worked perfectly too, because they had different last names as her.

"Derek, how'd the chiefs surgery go?" Meredith asked Derek.

"Great. We are expecting a full recovery." Derek smiled.

A sudden rush of relief came over Meredith, but could not be noticed by Derek.

"I'm on call tonight, but I was wondering if you wanted to go out tomorrow night." He gave her, what Christina called "the McDreamy" smile.

"Sounds great." She smiled as he leaned in to give her a kiss on her forehead.

What Meredith did not know, was that her step- father, who she called Dad, was watching through the window of his hospital room.

"I have another surgery, and I should be in there all night, So, I will see you in the morning?"

"Yes you will." Meredith grinned as she walked away to finish her rounds.

XXXXXXXXXXXX

Meredith was standing at the nurse's station when she felt someone put their hands to cover her eyes.

"Hmm… who could this be?' She smirked and turned around expecting it to be Derek, but it being the last person she expected.

"Addie…" Meredith grinned widely as she gave her a huge bear hug.

"Hey Mer!" Addison giggled. "Long time no see, huh?"

"Yeah, well you just had to go get married and only call every once in a while. I thought you were my boyfriend."

"Oh come on Mer, I call you almost every week. So when do I meet this boyfriend?" Addison asked

"True, but best friends are supposed to never separate." Meredith smiled. Addison rolled her eyes.

"So, what are you doing here?"

"You are changing the subject." Addison teased. "Your Dad called me, because there is a case here that he needs me for, and…" Addison trailed off.

"And?" Meredith asked.

"Let's go find an on-call room to talk." Addison pulled her over.

"So…" Meredith started as they sat down leaning against a wall.

"I needed to get away from New York." Meredith gave her a confused look. "I am pregnant." Addison confessed.

"Preg-… SERIOUSLY?" Meredith grinned. Addison looked down. "Not a good thing? Is your husband not happy about it?"

"My husband is here, screwing a slutty nurse, or something. I don't know the details really." Addison fiddled with her necklace that held her wedding rings.

"What a bastard." Meredith muttered.

"No, I really am over him. See, The baby isn't his. I fell in love with someone else…" Addison blushed.

"Who??" Meredith asked. Addison looked down at her hands.

"Addie… NO." Meredith said astonished.

"At first, it was a one night stand…" Addison said.

"It always is…" Meredith muttered.

"But, he really is committing." Addison smiled.

"My brother knocked you up?" Meredith questioned.

"What can I say? I have always had a thing for you brother." She grinned.

"What are you going to do about the husband?" Meredith asked.

"Divorce."

"Wow… I want to meet the bastard that cheated on you, though." Meredith grinned.

"Ah, Meredith, you will not kick my soon to be ex-husbands ass."

"Can I kick the slutty nurse's ass?"

"No." Addison smiled and got up, pulling Meredith along with her.

"I want to see your Mom and Dad." Addison said.

"Okay, but while in this hospital they act like they don't really know me."

"Typical Webbers." Addison laughed.

"Should I tell them the news?" Addison asked.

"Nah, wait for my idiot brother to be there."

"Okay. Come on." Meredith led her to the room where her father was.

They both walked in and Meredith closed the door and locked it.

"Hey Daddy." Meredith smiled. "How you feeling?" She smiled kissing him on the cheek. He smiled and looked up from his magazine.

"Just fine Mer. Addison." He smiled. "How are you?"

"Good, but the question here is how are you?" She smiled sitting down on the bed and holding his hand.

"Very good. Shepard did a wonderful job." He smiled.

"Course he did. He's the best." Meredith grinned proudly. Just then someone else walked into the room.

"I am the best." He grinned.

"Der!" She jumped up excitedly. "I want you to meet my bestest friend in the whole wide world…"

"Addison." He stood there shocked.

"Derek." She stood up. "I…"

"You two know each other?" Meredith asked.

"Yeah…" Derek trailed off. "Wish I didn't." He muttered

"He's my husband." She stated looking directly at Derek. "That's Derek."

Derek turned to Meredith. "Mer, I am so sorry." He turned back to Addison. "What are you doing here?"

"I didn't come here for you Derek. I am here for a case." Derek scoffed.

Meredith glared at him and turned back to Addison who was putting the pieces together.

"He's the boyfriend." Addison stated in shock. "Oh my god."

"I had no idea Addie." Meredith led tears fall down her face as she walked out of the room.

"Meredith?" Christina asked as she saw her best friend running out of the chief's room.

The chief cleared his throat.

"Sorry you had to witness all of that Chief." Derek apologized.

"Not as sorry as you will be when I am through with you. Cheating on your wife, who is like a daughter to me! Cheating on her WITH my daughter?" Chief asked forcefully.

"Meredith's your daughter?" Derek asked shocked.

"DAMN RIGHT SHE IS." Chief glared.

"But… I mean, you… and she…" Derek tried to form some words because he was completely confused.

"Step daughter, Derek." Addison glared as she fell into the seat.

"I'm sorry Chief, but you don't know the whole story, Addison cheated on me first." Derek said sitting down on another chair.

"I did, and I apologized Der. You should have at least waited for a divorce, but now you picked up and left and came here and broke my best friends heart." Addison stood up. "I am going to go find Mer."

Derek looked at the Chief from across the room. The Chief was still glaring so he got up and walked out of the room.

XXXXX

"Mer…" Addison said cautiously as she walked into an on-call room.

"Addie… I am so sorry. I promise I had no idea he was married, or that he was married to you." Meredith cried.

"Oh Meredith." Addison said sitting down next to her. "Listen to me. This is none of your fault. You didn't know. He didn't tell you. We will just blame all of this on Derek." She smiled.

"Okay. I just feel so guilty." Meredith wiped her tears.

"Well we are both adulterous whores." Addison smirked.

Meredith giggled. "Come on, we've got work to do, plus I want to see your mom! I heard she is in surgery and I haven't seen her perform a surgery in ages!" Addison smiled pulling Meredith up.

XXXX

Meredith was doing some research on the case that Addison had. Addison was going to let Meredith scrub in on the surgery.

"Your going into the gyna-squad? And here I thought you were going to follow in your own brothers footsteps, not that you could get any better then me." Mark grinned as he came up behind Meredith and put his arm around her.

Meredith turned around and smirked. "I hear I am going to be an Auntie." She smiled.

"You hear right." Mark just laughed and pulled her into a big bear hug.

"Congratulations Markie! I missed you." Meredith said in his ear as he hugged her tighter.

As they pulled apart Meredith saw a fist come in contact with Marks chin.

"What the hell?" Meredith yelled as she saw Derek on top of Mark beating the crap out of him.

"Derek! Get off of him!" Meredith yelled as she pulled Derek off of Mark.

"Addison cheated on me with him!" Derek muttered as Meredith pulled him away.

Everyone was watching the scene and soon Addison came in a rush to Mark's aid.

"What the hell Derek?" Addison glared as she looked at Marks cut on his cheek.

"Hon, go get this check downstairs." Addison whispered softly to Mark.

"I can do it myself." Mark mumbled as he walked off.

"I will go with him." Meredith said following him.

"Meredith…" Derek called after him.

"Stay away from me." Meredith hissed at him. "…and stay away from my family."

XXXX

"So which one of you is going to tell me why my head of neurology punched out a guy." The Chief asked strongly form his hospital bed. Ellis was standing next to him.

Derek turned to Addison and glared. "Go on Addie, tell them."

Addison groaned and buried her face in her hand and shook her face. "I am so sorry Richard. You two are going to be so disappointed."

"He was the guy who Addison cheated on me with." Derek told the Chief.

"Did you put your weight behind it?" The Chief asked quickly. Ellis hit her husband on his shoulder.

"What Richard means to say is, we can't have our personal lives come into the hospital. We are here to save lives." Ellis said firmly.

"Yes ma'am." Derek nodded.

"Who is this jackass anyways?" Chief asked looking over at Addison.

Addison groaned again.

"My best friend Mark." Derek grumbled.

"Mark?" Ellis asked with a slight smile trying to contain for laughing and turned to Addison. "Mark, Seriously?"

"You are starting to sound like Meredith, Ellis. But yeah, It would be our Jackass." Chief sighed. "You two always had a thing for each other."

Addison blushed.

"What are you talking about? You knew Mark before I met you?" Derek asked Addison.

"Yeah..." Addison pulled her hands away from her face.

Just then the door opened and in came two people. Derek's Jaw clenched.

"Well look what the cat dragged in." Richard laughed at the sight of his daughter pushing his son into the room. Mark had stitches on his cheek and was holding an icepack to his eye.

"Hey did the sutures himself. He would not let his own baby sis do them." Meredith stated in shock.

"I don't trust you just yet, Mer." He grinned.

"Hey Mom, Hey Dad." Mark smiled and walked over to give him hugs. "Hey Derek" Mark grinned.

"Mark." Meredith warned. "Don't taunt. What are you, Five?"

"What the hell is this?" Derek asked in confusion. "How do you know Mark?" Derek asked Meredith.

"Mark is Meredith's sister." Addison said taking her face out of her hands. "Richard and Ellis were Attendings at the hospital that I did my internship at, with Mark, and Meredith was in med-school at the time. We met and became close friends, along with Mark. Then Mark and I had a series of, uhm drunken nights and I decided to move to New York, where I met you. Then Mark showed up begging me to come back here to Seattle with him, but I was already married to you, who he told me was his best friend from Med School." Addison explained to Derek. "I told him the night he came back that we were to act like we never met before, but the feelings for him came back. I ignored them for a few years, but one night it just all caught up with me."

"We all know what went from there." Mark winked at Addison.

"Mark! Behave yourself. Must you act like a damn child? Home-wrecker." Ellis scolded.

"I missed you Mom." Mark grinned as he out his arm around her shoulder.

"I have a surgery, I will leave you to your happy family time." Derek got up and left.

Meredith watched him leave with a frown on her face.

"Meredith, your father told me about you and Derek." Ellis looked at her daughter with concern written all over it.

"You were with Der?" Mark asked trying to contain his laughter. "This world is just too small."

Meredith just nodded.

"You holding up okay?" Addison asked.

"Yeah, I am fine. He doesn't even matter." Meredith lied.

"Are you sure?" Richard asked.

"Yeah." Meredith nodded. "Hey guys tell mom and dad the great news!" Meredith told Mark and Addie in order to change the subject.

"What good news?" Ellis asked.

"Well…" Addison grinned.

"I knocked up Addie." Mark blurted out with a huge smile planted on his face.

"Mark." Addison rolled her eyes. "I am three months along." Addison smiled.

"Congratulations, when's the wedding?" Ellis asked with a huge smile as she put her arm around Mark.

"Wedding?" Mark asked, his face turning as white as sheet.

Meredith busted out laughing along with chief.

"We're not engaged." Addison smiled. "Just having a child."

"Well congratulations Addie, I know for a fact you will be a wonderful mother.

"I hope so." Addison blushed.

"You know, with a baby and all, you're going to need family around. To help, I mean." Ellis smiled looking down at Richard.

"And what would you know, we are looking for a head of OB-GYN and Plastics." Meredith smiled at her dad.

"Oh guys, I think they are on to something." Meredith smiled.

"We'll think about it Dad." Mark took a seat and pulled Addison onto his lap. "It'd be nice to be closer to home."

"Sure would." Addison kissed Marks cheek.

Meredith looked at the happy couple and wondered if Derek and her would ever work out.

It didn't seem to bother Addison that she was with Derek. She really moved on, so maybe it could work.

"Meredith." The chiefs' voice brought Meredith out of her thoughts.

"Yeah?" Meredith looked around and noticed that her mom, her bother, and Addie had all left the room.

"You okay?" Richard asked.

"Yeah, I am good Dad. I just really loved Derek." Meredith looked down at her hands. Richard motioned for her to go lay down next to him on the hospital bed. Meredith could always be honest with Richard. Maybe it was because he wasn't her real father, but she always had a connection with him.

Meredith crawled onto the bed and laid her head on his shoulder.

"Derek's a great guy. He made a mistake, but so did Addie, and look at how happy she is. I know for a fact that you make Derek happy, and I am pretty sure he makes you happy, right?"

Meredith nodded; tears were falling down her cheeks.

"Then don't worry Mer-Bear. Everything will work out. I promise." He kissed the top of her head.

"Thanks Daddy." She cried into his shoulder.
