I just wanted to say that I thought this was one of the best episodes in a long time. I know that there are lots of people who don't like the speeches that Arizona seems to be giving every week (and sometimes I agree), but this week I thought they were spot on. I loved everything about this episode; from the Arizona-centric story line to little peace of development with Karev.
I think all of the actors did an amazing job. I loved the guest stars this week, especially Wallace and his parents. They were phenominal.
I hope Shonda & Co can keep this momentum going and continue to bring us thought provoking and well scripted episodes like this past one.
