Cristina: How are you fine? How are you just completely fine? I'm ruined, okay I'm dead. I am wrecked. And you're just what, walking around babysitting me? As if you didn't go through the same thing too. Why are you okay?
Meredith: I don't know.
Cristina: You know what, you were there too. You were there too with your sad eyes screaming at me to save his life. Telling the guy to shoot you and not giving a crap about yourself or your pregnancy. I didn't have a choice. And you did that. If it was anyone else on the table, if it was anyone else standing there I would have walked away.
Meredith: You could not have walked away.
Cristina: I could have walked away and then I wouldn't be here!
