Grey's Anatomy, Season 12

Amelia:
Meredith, I am flipping out here. I'm wearing a wedding gown. There is a good and decent man in there who loves me and is expecting to marry me, and I can't tell if I am marrying because I love him back or because I just ran here and picked up a scalpel and slipped into this Shepherd skin. And maybe it is right, and maybe it's not, but I don't know, and I am marrying Cristina's husband. I know what you think about that. And I don't know what I'm doing. And there is no one here with me. There is no one here to tell me to quit or get me down the aisle or help me. That is Derek's job, and Derek is dead. And all I have is Maggie, and Maggie is full of sunshine and candy and hope, and every time I try to tell her that the world is on fire, she hands me a marshmallow to roast, so that just leaves you. And you... you are rooting for the other guy. You told me to go and be with Owen, and then you turned on me, and now you are not on my side. And we both know you don't like me, but you are stuck with me. So here I am in a wedding gown on the happiest fricking day of my life in a room with no family and no help and no one on my side but you. So what can you do for me? What can you do for me, Meredith?

Meredith:
You're me.

Amelia:
What?

Meredith:
You're me before Derek. I can be here for you. I know how to do this. I can be a twisted sister for you. Just how do you want to play this? Do you need me to tell you you're a beautiful bride and kick your ass down that aisle? You're a beautiful bride. Turn around. I'll start kicking. Do you need me to call your mother and yell at her? I'm your girl. If you need a shoulder to cry on, I have two. If you want to freak out and call it off, if you want to run, I'll drive the getaway car. Just let me know what you need. I'm here for you. I am your family, Amelia. Today, I am your person. Just tell me what you want to do.
