I think the point was that no one was supposed to know what code black was except for the residents (is that the right word? I get them confused). I think it made it more interesting that no one really knew what was going on. And I think the woman that plays Addison was brilliant in that episode. I know we're supposed to hate her and want McDreamy to get back with her, but I can't help liking her.
My favorite line from last nights episode:
Meredith: "She's got my McDreamy, she's got my McDog. She's got my McLife."
"This table, he is over one hundred years old. If I could, I would take an old gramophone needle and run it along the surface of the wood. To hear the music of the voices. All that was said." - Doug Wright, I Am My Own Wife
