Sorry it took so long to update. I've been really busy. I hope it's worth the wait!

Addison, Derek, and the girls were walking on the beach of their Oceanside resort when they spotted Derek's mother, sisters, and their husbands. Lily went running ahead to greet them.

"HI!" Lily yelled while running.

"Hi." Derek's mom said back.

"I get to wear a pretty dress tomorrow." Lily told them.

"So do we." Nancy said. Addison and Derek caught up.

"Hello everyone." Derek greeted.

"Hi." They all responded.

"There's my granddaughter." Carolyn said taking Grace from Derek.

"She's gotten so big." Kathleen commented touching Grace's head.

"She's eight months old now." Addison informed them.

"And gorgeous." Sarah added.

"Are you nervous for tomorrow?" Kathleen asked.

"No." Derek responded smiling. "I don't even know why we have to have another wedding."

"You need to be married again." Nancy said.

"I thought we could go to the courthouse." Derek told her.

"But this is going to be so pretty and fun." Addison said.

"And we get to wear pretty dresses." Nancy said copying Lily.

"Yes I've heard about these dresses." Derek said.

"So what's first on the agenda?" Carolyn asked.

"We have the rehearsal in an hour and then dinner." Addison said looking at her watch.

"And then bachelorette party!" Sarah said.

"So that's why you all didn't bring kids." Derek said.

"Yes it is." Nancy replied.

"I think we should all go get cleaned up. Where is the rehearsal?" Carolyn asked.

"We are supposed to meet the wedding coordinator in the lobby." Addison told her.

"In an hour?" Carolyn asked confirming.

"Yes."

"Let's get moving everyone." Carolyn said keeping all of her children in line even though they are grown adults. They began walking back to the hotel.

"You look bored." Derek said to Kaitlyn.

"I was having fun on the beach." She told him.

"We should have brought Will for you. You have no one to hang out with." Derek said.

"It's okay. I'll watch Lily and Grace tonight if you and Addison are really having bachelor parties."

"It's sounding like we don't really have a choice, do we?" Derek said. Kaitlyn laughed.

"Not really." She said.

Later…at the rehearsal dinner…They finished eating and were dancing a little bit. Everyone was really happy to be together and they were all having a good time. A woman who closely resembled Derek walked in the room. They all stopped what they were doing and stared.

"Hi!"

"Amelia." Addison said.

"Did you come to ruin Derek and Addison's wedding?" Nancy asked.

"No. I came to have some fun. They're already married anyway." Amelia replied.

"We thought you were dead, Amelia." Carolyn said.

"I've never been better." Amelia told her smiling.

"Last time we saw you, you were getting high off pills with Beth." Nancy said angrily. "You just left. We didn't know where you were, what you were doing, if you were even alive."

"I'm here. I'm sober. I was in rehab. I'm ready to make amends." Amelia announced. Everyone just stared at her.

"You hurt us." Derek said upset.

"I know and I'm sorry. I'm better, really. I want to be here with you all." Amelia told them.

"I can't do this Amelia." Derek said walking out of the room.

"Derek wait!" Amelia said starting to go after him. Addison grabbed her arm.

"Leave him alone." Addison told her. "I'm going to put my kids to bed and talk to Derek." She took Grace from Sarah and grabbed Lily's hand.

"You have kids?" Amelia said surprised. "I have been gone too long." Addison left with the girls. Sarah pulled Amelia into the hallway.

"Tell me what's going on. The truth." Sarah said to her.

"I already told you the truth. I went to rehab. I've been sober for 9 months. I'm back to practicing medicine. I came back because I want to be a part of everyone's lives again." Amelia told her.

"That's great Amelia. Really. I'm proud of you. Nine months is a long time, I'm really proud that you've been sober that long." Sarah said.

"Thanks." Amelia replied.

"You have to understand how everyone felt, not knowing where you were for four years. I'm ready to welcome you back into my life with open arms. You're my sister. And I want to help you, but you have to know that everyone else may not be as understanding at first. Also you need to keep your behavior in check for this wedding. This weekend is not about you. Addison and Derek have worked very hard for it. " Sarah lectured to Amelia and seemed to get through to her. Amelia gave her a hug. "Promise me you're not going to deliberately upset anyone this weekend."

"I promise." Amelia said. "So why exactly are Derek and Addie renewing their vows?"

"They aren't renewing their vows. They are getting married." Sarah told her.

"But they are married." Amelia said.

"They're divorced." Sarah informed her.

"What happened?" Amelia asked.

"The short version. Addison slept with Mark. Derek ran away to Seattle. He had a relationship with an intern. Addie followed him and tried to get him back. They got divorced. Addison started dating Mark. Derek cheated on his intern with Addison. She got pregnant. Derek and the intern broke up. And now we're here for them to once last time confess their love for each other and live happily ever after." Sarah caught her up.

"Wow. And the kids?" Amelia asked.

"The baby is Grace. She is Addie and Derek's baby. Lily is Mark and Beth's daughter. And you know Kaitlyn. Where is Beth?" Sarah asked.

"I haven't talked to Beth in a year. I think she's in jail. Ask Mark, he has Lily now. All I know is I was ready to get my life back and she wasn't so we parted ways." Amelia said sadly.

"That's good for you though. You need to get your life back." Sarah encouraged her.

"Will you help me deal with the rest of them?" Amelia asked.

"Yes, but you need to apologize to mom and keep your distance from Derek until his wedding weekend is over." Sarah informed her of the conditions of their agreement.

"Okay." Amelia said. "It's good to be back."

"How did you find us anyway?" Sarah asked.

"I called Nancy's house. Her babysitter was more than happy to fill me in on the wedding and where it was happening."

In Derek and Addison's hotel room. Addison was bathing Lily and Grace. Kaitlyn was reading. Derek was sitting in the other room ranting to Addison.

"I can't believe she is here. After all that she did to us. She has the nerve to show up and ruin our wedding. She couldn't have waited two more days to show up. Or for that matter she couldn't have been telling someone she's been alive for the past four years." He ranted.

"She hasn't ruined our wedding." Addison said as she rinsed the shampoo out of Lily's hair.

"Not yet anyway. Who knows what kind of tricks she has planned. She's always the center of everything." Derek said.

"Give her a chance. She seems like she's changed. Maybe she really does want to make amends. She's sober." Addison said fighting for Amelia.

"For now." Derek responded.

"Derek you cannot treat her like that. Being sober is huge. You need to be supportive." Addison lectured Derek. "Come help me." He came in and took Grace as Addison lifted her out of the bathtub. "Just give her a chance."

"One chance." He said.

"Tonight I just want you to go out with the guys and forget about Amelia. Have some fun. Hopefully be in good shape for our wedding tomorrow." Addison said making Derek smile. She helped Lily out of the tub.

"I want you to have fun tonight too." He told her.

"Oh it will be fun. Probably all gossip about Amelia but that'll be fun." Derek kissed her.

"I love you." He said.

"I love you too."

Addison walked down the hall and knocked on the door. Kathleen opened it.

"The bride is here!" Kathleen announced.

"The kids are in bed. Derek is out. I'm here to have fun." Addison informed them.

"Yay!" Everyone cheered.

"We're staying in tonight. Amelia's been making her amends with everyone so in support of her we aren't going to a bar." Sarah told her.

"Sorry." Amelia said to Addison.

"I should be thanking you. An 8 month old and five year old waking me up early and a wedding tomorrow. Last thing I need is to go out." Addison said walking over to Amelia. She hugged her. "Welcome back."

"Thanks." Amelia said hugging Addison back. They all sat down. "I want to know about the major events I've missed in all of your lives."

"Besides Derek and Addie, you've pretty much just missed new babies." Kathleen said.

"Fill me in." Amelia demanded.

"None for me." Nancy told her. "Five is enough."

"You were pregnant when I left." Amelia said to Sarah.

"Yup. I had a little girl. Her name is Hannah. She's four now. I also have a little boy." Sarah said.

"A boy!" Amelia was excited.

"Yes. He's almost two." Sarah said smiling.

"So you have five now?" Amelia asked.

"Yes." Sarah said. "Kathleen too."

"You all do? Just like mom." Amelia said.

"I have another girl. She's three." Kathleen told Amelia.

"What's her name?" Amelia asked.

"Olivia." Kathleen said.

"How old are all of the kids now?" Amelia wanted to know.

"Colleen is fifteen, Lauren's twelve, Matthew's seven, Annie's five, and I just told you Olivia's three." Kathleen said.

"I told you about Joseph and Hannah, Elizabeth is ten, Margaret is eight, and Emma is six." Sarah told her

"How about your kids?" Amelia asked Nancy.

"Jake is fifteen, Walker is thirteen, Logan's ten, Paige is seven, and Rosie is six." Nancy told her.

"They're all getting so old." Amelia commented.

"You missed four years of their lives." Kathleen told her.

"I know. You can't even begin to know how much I regret it." Amelia said sadly.

"But you're here now. You'll get to make so many new memories." Addison tried to encourage her.

"Oh you have a baby now too." Amelia said.

"I do." Addison told her.

"Grace right?" Amelia asked.

"Yes. Hopefully you'll get to know her for her entire life." Addison said.

"Yeah you'll have plenty of baby time with Addison's babies. She needs to have four more to catch up with the rest of us." Nancy said.

"I don't know about catching up but you're more than welcome to spend time with your niece." Addison told Amelia.

"Are you ready for your wedding?" Amelia asked.

"Yes. It's more like a show for everyone else at this point." Addison said.

Wedding day….

Derek stood at the alter on the beach with Mark as his best man and his brothers in law as his groomsmen. Many of their friends from work gathered together to watch. Cannon in D began to play and each of Derek's sisters slowly walked down the aisle in their flowing blue strapless dresses, followed by Kaitlyn, and then Lily in her beautiful flower girl dress that she had been waiting weeks to wear. As the music changed to the wedding march, everyone stood and turned their heads to see Addison looking magnificent in her simple white gown, similar to her bridesmaids but longer. Derek couldn't help but grin widely as she joined him at the alter.

"Dearly beloved, we are gathered together to witness the union of Derek Michael Shepherd and Addison Adrienne Forbes Montgomery in holy matrimony. To celebrate their love and devotion to one another. To send them on the wonderful journey of marriage." The priest began the ceremony. "Addison, do you take this man to be your husband, to live together in the covenant of marriage, to love him, comfort him, honor him, and keep him, in sickness and in health, forsaking all others, be faithful to him as long as you both shall live?"

"I do." Addison said.

"Derek, do you take this woman to be your wife, to live together in the covenant of marriage, to love her, comfort her, honor her, and keep her, in sickness and in health, forsaking all others, be faithful to her as long as you both shall live?" The priest addressed Derek.

"I do." Derek said.

"Derek, repeat after me. I, Derek," The priest said.

"I, Derek," Derek repeated.

"Take you Addison to be my wife."

"Take you Addison to be my wife."

"To have and to hold from this day forward,"

"To have and to hold from this day forward,"

"For better or worse."

"For better or worse."

"For richer, for poorer,"

"For richer, for poorer,"

"In sickness and in health."

"In sickness and in health."

"To love and to cherish."

"To love and to cherish."

"Till death do us part." The priest said the last part.

"Till death do us part." Derek finished his vows.

"Addison, repeat after me. I, Addison," The priest said.

"I, Addison," Addison repeated.

"Take you Derek to be my husband." The priest continued.

"Take you Derek to be my husband."

"To have and to hold from this day forward,"

"To have and to hold from this day forward,"

"For better or worse."

"For better or worse."

"For richer, for poorer,"

"For richer, for poorer,"

"In sickness and in health."

"In sickness and in health."

"To love and to cherish."

"To love and to cherish."

"Till death do us part." The priest said the last part.

"Till death do us part." Addison repeated the last part just barely holding the tears in.

"The rings please." The priest said. Mark handed over the rings. "The wedding right symbolizes unity, a circle unbroken, without beginning or end. Today Addison and Derek exchange these rings and a confirmation of their vows to join their lives, to work to create a life that is complete and unbroken, to love each other unconditionally. May the lord bless these rings which you give to each other as a sign of love and fidelity." The priest handed Derek his ring for Addison. "Place the ring on Addison's finger."

"I, Derek, give you Addison this ring, as a symbol of my commitment to love, honor, and cherish you. With this ring, I thee wed." Derek said as he slid the ring on Addison's finger. Addison took the other ring from the priest.

"I, Addison, give you Derek this ring, as a symbol of my commitment to love, honor, and cherish you. With this ring I thee wed." Addison placed the ring on Derek's finger.

"Before their friends and family, Addison and Derek have pledged their everlasting love and commitment for one another, I now pronounce you husband and wife. You may kiss the bride." The priest finished the ceremony. Addison and Derek kissed while their family and friends cheered.

I hope you liked it. That's the end of this story. I have a lot more to write about all of these characters, but I think it's time to start fresh. I'm planning on writing a sequel very soon. Thanks for taking the time to read it and write reviews!
