Meredith, Amelia, and Maggie are sitting in the back of the ambulance on their way back from the scene of the accident. A tunnel entrance collapsed during rush hour and they were called to the scene with April to help a man crushed inside of his car.

"Maybe if we" "It wouldn't have worked" Meredith says interrupting Maggie. "Yeah. No." "He didn't have a chance. It was the right call" Meredith adds. Amelia turns to Meredith looking very pissed off. "Huh" she says angrily. Meredith looks at Amelia in confusion. "What" she says. "You know when to make the right call in every situation don't you Meredith. Whatever you think is best, that's what gets done, am I right?" Amelia breathes heavily after her little rant and turns to stare at the wall of the rig. Meredith looks at Maggie in confusion but no one says anything. As soon as they pull into the ambulance bay Amelia hops off the rig and turns to walk inside. "You had no right saying that to Owen. What I do is none of your business and I don't care who asked you to look out for Owen, what we decide to do with our lives is none of your business." Amelia storms off quickly while Maggie stares at Meredith. Meredith rolls her eyes; "Derek told me that Owen is planning on proposing to Amelia and I just asked Owen if he thought marriage was the best idea because they both have some serious issues. I only asked because I don't want to see either of them hurt." "She obviously took it the wrong way. You should go explain" says Maggie. "She can take it anyway she wants. It's my job to look out for Owen, I've seen him in some pretty dark places. Derek can deal with Amy, she's his sister." "You're her sister too." "Christina is my real sister. She is the most important person in my life after Derek and my kids so whatever she needs comes before Amy." "But Amy obviously needs a sister right now and you're the only one she has out here." Meredith stares at Maggie for a moment before picking up her bags and walking inside. "If she comes to me I'll talk to her" Meredith calls over her shoulder.

"Hey how's your patient? I heard you brought his baby down to him in the car" Derek says coming up to Meredith. "He's in surgery now" she replies giving him a quick kiss on the cheek. "Something is going on with Webber and Catherine" she says. "What do you mean?" "They've been yelling and glaring at each other all day, I think they even cancelled the wedding." "Well we have to do something" he says. He takes her hand and pulls her into the attendings lounge where he noticed Richard working on charts earlier. Meredith and Derek start getting their things together when Catherine walks in. She goes over to the coffee machine and Richard walks over to her. They stare at each other angrily for a moment before Richard turns around and walks away from her. Meredith and Derek look at each other and Derek gives her a 'you talk first' look. "What is the matter with you two" she asks. "My husband almost died and I almost died multiple times. My mother is dead and my sister is dead. Yeah, I'm gonna play that card." She fixes her gaze on Richard. "You" she says angrily. "You walked away from Ellis, never got to be with her, and now she's dead. Adele is dead." She turns to look at Catherine. "And you – I don't know who's dead for you. But the both of you are very, very much alive, and breathing, and driving each other crazy. And you yell, and argue, and fight, and you both should be thrilled to do those things. I would give anything to be able to do those things with Lexie, and to make sure I can do those things with Derek for the rest of my life. And none of those things are reason enough to not be with the person that you love, especially when there just isn't enough. There will never be enough time." Derek puts a hand on Meredith's shoulders as tears appear in her eyes. He takes over for her saying "You both know that. You both know that time is precious. So whatever it is that's coming between you two, will you just please figure it out already?" Richard and Catherine look at each other with shame for their actions on their faces. "Please just figure it out" Meredith says. Derek and Meredith pick up their bags and leave them to talk. Derek wraps an arm around Meredith as they walk down the halls and kisses her on the head. He knows talking about his accident, her mother's death, and Lexie's death is hard for her so he just lets her grieve in silence. "I really hope they work it out" Meredith finally says. "I think they will" he says confidently. "How can you be so sure" she asks. "Because Richard has always been a romantic, like me. When he loves someone he fights for them, hard."

A few hours later Derek and Meredith find themselves sitting in the chapel watching Richard and Catherine get married.

Everyone starts to clap and cheer when Richard leans down and kisses Catherine at the end of the ceremony. "You know how we can make this even better" he asks with a sly smile. Derek suggests having the reception at their house and Meredith quickly agrees. They have the cake and decorations sent over so that by the time everyone gets to their house the furniture has been moved from the living room so it looks like a hotel ballroom. "Thank you for this" Richard says with a smile. "It was all Derek's idea" Meredith replies with a smile. "I know I've never formally told you this but I do consider you family Meredith." Meredith smiles even wider if that's possible. "Congratulations Richard" Derek says coming up to them. "Thank you for having us Shep it means a lot" Richard says. "It's our pleasure." "Excuse me but Dr. Webber has a couple of moves I haven't seen yet" Catherine says as she grabs Richards arm. She pulls him onto the dance floor and they hold each other lovingly. Derek wraps an arm around Meredith and they stand there for a minute just watching the newly-weds dance. He turns her so she's facing on of the guest bedrooms. "Go talk to her" he says with a nod towards the bedroom door. Meredith can see that Amelia is sitting on a bench alone, looking very sad. He gives her arm a squeeze before she takes a deep breath and walks towards her sister. "Hey." "Hi." Meredith closes the door behind her and sits down next to Amelia. "I didn't say that I disapprove of you and Owen, I just want to make sure that you two are going to be okay. I've known Owen for a long time and I've seen the worst of his PTSD; it's not pretty. And you have your own issues that you work to deal with every day." "I'm not this weak little victim and neither is Owen. You don't need to" "I know you're not weak. You're one of the strongest people I know." "Then why did you" "Because I used to be you" Meredith says forcefully. Amelia opens her mouth a little, but closes it without saying anything. "My dad abandoned me when I was 5. I saw him for the first time since then during my first year as an intern. A few weeks later I found out he had a whole other family with two daughters that I never knew about. Then my mother who was suffering from Alzheimer's woke up and told me that I was a failure and she had spent the last few weeks telling me she wished she'd never had a kid. Then I almost died. Then my mother died. Then my step-mother died after being the first parent-figure to really care about me. Then my father blamed me for he death. Then Derek asked me to break up with him." "Why are you telling me this" Amelia finally says. "Because I was so damaged after my life falling apart over the course of a few months that I couldn't let anyone love me. I went to therapy. And it wasn't until I got help that I was finally able to move on with my life and be happy with Derek. Yes, I still had my trust and abandonment issues but I figured out how to deal with my problems. I just want to make sure that you and Owen have handled your problems because if you try to start a life together while you're both still suffering it's not going to end well. And I want you two to be happy." Meredith puts her hand over Amelia's and gives it a squeeze. "We help each other through our issues, keep each other in check. He helps me feel like I don't have to be ashamed of my problems." "I can tell that he makes you really happy." "He does" Amelia says with a smile. "I just want you to be okay." "I will be. Because I have Owen." Amelia rests her head on Meredith's shoulder and Meredith puts her arm around Amelia's back. They sit like that for a few minutes before Jackson comes in and tells them it's time to cut the cake. After enjoying cake with Derek, Amelia, and Owen, Meredith notices Maggie sitting outside on the porch by herself. Maggie wipes a few tears from her eyes as Meredith approaches. "What is wrong" Meredith asks, her voice filled with concern. "And don't say you're fine" she adds as Maggie says "nothing, I'm fine" at the same time. "What – did somebody die?" Meredith hears Maggie's sobs from a few feet away. "Oh. Phhttt. My parents are getting a divorce" Maggie says turning to look at Meredith. "My mom called at told me today. She's been having an affair with the man that services their cars…for 11 years." She chuckles and lets another tear fall down her face. "He's been servicing their cars and my mom. And my dad found out about it years ago, and he was enraged, and he stuck with it for me, because I was…I was still in town. I was always around you know, so they held it together for the kid. Classic. Except the kid's a grown woman. They wanted to preserve my…happy, idyllic…pathetic, crap-filled lie of a childhood!" She starts crying a little again so Meredith sits down beside her. "Why didn't you tell me?" "I…I am crying like a 7 year old over mommy and daddy. I…didn't grow up like you, I've never lost anyone. I never even had a cat die, I still have all my grandparents. There's no darkness in my life. Just, I've never had it. So I-I'm not gonna come talk to you about it." "Well, you should always come talk to me…because whatever it is, chances are, I've seen worse, and I am qualified to tell you how you'll survive. You should always come talk to me." Maggie smiles at Meredith before leaning her head on her shoulder and letting out a big breath. Now it's Meredith's turn to smile; despite what she says she loves being a big sister. They both look up to see Amelia walking out of the house towards them. Amelia and Meredith smile at each other briefly. "What are you crying about" Amelia asks Maggie. "What are you crying about" she asks in return. Amelia just sighs and sits down next to Maggie so she can lean her head on Maggie's shoulder. "This is why Derek built this house" Meredith says as she looks at the party. "He wanted to fill it with noise and people because he came from this big, noisy family." The three sort-of sisters sit in silence, just watching the party. "Okay, we have to dance it out" Meredith says. Maggie looks at Meredith in confusion and Amelia says "what?", just as equally as confused as Maggie. "What does that mean" asks Maggie. "Let's go" Meredith says as she stands up. She stands in front of Maggie and Amelia and reaches her two hands behind her to pull her sisters up. Meredith pulls them onto the dance floor and they dance it out like nobody's watching. Eventually Callie, Bailey, Catherine, and Richard join in making it one big dance party.

I know this chapter doesn't have a lot of Meredith and Derek but I think it's important to show the relationship between Meredith and her sisters, since that is what the show's writers focus on in the 12th season. Obviously I made some changes in the Omelia timeline but I think they would never have ended if Derek hadn't die so after dating for almost 2 years it makes sense that Owen is thinking about marriage. The next chapter will focus more on merder and the kids so don't worry!
