Two years later…

She hadn't been in Seattle since she left six years earlier for LA. Since she walked away from her job. Since Derek walked away from her. And since she walked away from Mark. Her black dress moved from side to side with each step and her red hair blew back slightly. There was a large amount of people that filled the room. People she hadn't seen or talked to since she left. She took a seat near the back hoping nobody would notice her.

Her eyes were glued to front of the room. She noticed the people crying through out the room as they waited for the service to start.

"Addison?" His voice pulled her from her thoughts. She looked up to see her ex-husband standing there.

"Derek." She said.

"What are you doing here?" He asked. She glared at him.

"What do you think?"

"Sorry." He sighed and sat down beside her. "You look great."

She looked over at him. "You too." There were a few seconds of silence. "I can't believe Richard is gone."

"Yeah, me neither."

They both watched the front of the room. Addison's eyes fell on two people she knew well as they walked in. Both had ruined her marriage with Derek though she blamed herself more than them. Mark and Meredith. They walked in from the front and took a seat in the second row beside Christina.

"Meredith and Mark?" She asked.

"Yeah, not long after you meet and Meredith and I broke up. Mark left like a year and a half later for some reason; I never heard the true answer. Meredith left soon after. She came back first with twins actually. Zachary and Brooklyn. Mark came back soon after that."

"Were they his?"

"The twins?" She nodded. "Yeah."

"So they're together now." She couldn't help but feel a twinge of sadness in her gut.

"Married actually. A year and a half. She's pregnant with their third." He sighed. "It took forever to get used to."

"Wow. It's hard to believe her settled down." He nodded.

Meredith leaned into Mark as tears rolled down her cheeks. Mark stroked her arm trying to comfort his wife.

"He's really gone." She said wiping her cheeks.

"I know, Babe." He kissed her head.

The service began and people took turns talking about Richard. It came Meredith's turn. Mark squeezed her hand in support as she walked to the podium.

"Um, I'm Meredith Sloan." She wiped her eyes so she could see clearly. "Richard was practically my father and my children's grandfather. I love him dearly. He gave me support. I remember one time that I told him he wasn't my father and stop trying to be. It took me a while to realize, he was more my father than anyone ever had been." She wiped a tear from her eyes. "He wasn't only a great chief of surgery but he was also a great person and a great father figure. We all love him so much and he will be missed. I already do miss him. Thank you." She walked back to her seat and Mark hugged her as she sat down.

------------------------------------------------------------------------------------------------------------

Mark hugged Meredith as she talked with Christina after the service ended. She leaned back into his embrace as Christina walked off.

"Are you okay?" She turned around and rested her head down on his chest.

"Yeah." She whispered into his chest. Someone cleared their throat. Meredith turned around to see who it was. "Dr. Montgomery." She said surprised to see her there.

"Call me Addison." Addison said.

"It's good to see you, Addison." Mark said.

"I hear you two are married." She said and Mark and Meredith nodded. "Congratulations for that and the kids."

"Thanks." Meredith smiled uncomfortably. "I'm going to go talk to George." Mark nodded kissing her cheek before she walked off.

"You look good, Mark." Addison said.

"You too. How's LA?"

"It's good. How's Seattle?"

"Good."

"You really love her don't you?"

"More than anything."

Addison let out a sigh. "We've all come a long way from the three party animals back in college in New York."

Mark chuckled and nodded. "Yeah we have."

"It's weird, huh?"

"What?"

"Everything that happened. You know, if we hadn't slept together all those years ago none of this would have happened. Derek and I would still be married and you would still be a manwhore."

"How do you figure?"

"Well, if we hadn't have slept together, Derek wouldn't have came here. If I hadn't followed you would've never came here and met Meredith. We would all still be in New York, best friends and all, instead of me in LA, you and Meredith here and married, and Derek here."

"Yeah, I guess it was the best mistake of my life."

"Yeah, I guess mine too." She sighed. "I've missed you guys."

He smiled. He hadn't really thought about her over the last two years. She was part of the past, a big part of it, but still the past. Meredith was his present and future. "I've missed you too, Addi."

"I should go find someone else. Is Callie around here?"

"Should be."

"I'll see you around, Mark."

"Yeah, see you." He sighed as she walked off and couldn't help but think what their lives would have been like if Derek had never walked in on them having sex that night.

"Hey." Meredith said.

"Hey."

"Let's go home. I can't be here anymore."

"Me neither," He took her hand and lead her to the door. Meredith stopped and looked back at the picture of Richard at the front of the room. "Good-bye, Richard." She said quietly before walking out with Mark.
