Meredith: Is that what this is about? Derek? It's always going to be about Derek?
Cristina: Okay, fine, it's not about Derek, it's about you and me, and the fact that you didn't have my back in that room!
Meredith: What would you have wanted me to say...
Cristina: I don't know, anything! You should have said anything! You have a relationship with the Chief. You have his ear. But you didn't say anything to defend me! Because this isn't just on me. You just stood there and you watched him take me out of the running for solo surgery. You let me take all the blame. But the fact is that we all had interns in that room. We all failed to supervise them. And if your friend had died in there, that would have been on all of us too. You should have said that.
