I don't know- I was actually impressed at he scene when Yang called out Grey. Once upon a time, Grey was about as promising as Yang and she is the title character. It must have been hard to be put in her place like that by a peer.
I also thought it was interesting commentary on he debate as to whether or not women can have it all.
What I did think was idiotic was that she was only pumping one side. You don't know any better Meredith, really?!
I also loved that they explored this aspect of Meredith's character and of working moms in general. However, it seems weird that Meredith is dealing with this type of difficulties just now, given her history with her own mother and that she already had a child.
