Susan is back! I remember when she left in one of the earlier seasons I didn't think that she is gone forever. But by now I already wasn't thinking that she will be back, so it was an interesting surprise. While I am sad Dave is gone, having Susan back is a great addition. Will be interesting to see how it will be from now on.
Dr. Chen ended up having to resign because of the mistake that killed a patient. I am not sure why she is mad at Dr. Weaver. Thee only reason some tried to make it her responsibility was because Dr. Chen still wasn't eligible to be a chief resident because of not having worked enough days based on her maternity leave, but this was a favour Kerry did for her, and the mistake was indeed Chen's. So Carter may be chief resident now, that would be awesome. The show started when he was just a new student and now he is already that far.
