I didn't realize that they replayed the wedding show before ... I wish I hadn't missed that! I loved the dynamic between Burke and Christina - as good as it ever was. I thought the way they played it was perfect -- both of them had moved on, both were in a good place, but both clearly remembered what it was that drew them together and couldn't quite shake it. It seemed very true to life to me. It also seems like they are clearly setting up Amy to be the replacement character for Yang. That seemed obvious to me after the back and forth about whether she was Amy or Dr Shepard. I wonder how that is going to work for Meredith though. Are they somehow going to make her into the sister that Meredith never quite had?
