A. Nope, never saw it coming. I did pick up that Kate was weary of the ordeal, but that is about it. It did change my view of Anna pretty quickly.
B. Surprised, yes, disappointed, no. I thought it was a good ending to the story (not for Anna, obviously). As story telling, it worked. That was the event that could bring the family back together, dodge the transplant question, and produce a good result for everyone else but Anna. A sacrificial lamb, in a manner of speaking.
C. Campbell? Liked him. Slick on the outside, but with a good heart, and a lot of trouble admitting it. Nice little romantic interest story to have running on the side.
I'm fine with using modern medical methods to facilitate having children; I am uncomfortable with the idea of people screening embryos for anything other than genetic diseases. I think it was a mistake for Brian and Sara to screen for a suitable donor, for instance.
