I thought it was a great episode, but I think that ABC ruined it by promoting it in a way that gave it all away. When Justin Chambers was on The View, they started asking him questions about "will the wedding happen" and he was very elusive. The moment that happened, I figured that Alex and Izzy would get married instead of meredith and Derek. It was just too convenient to have Meredith and Derek get married that quick and easy. As a result, every single hint and nod they had last night that it would be those two getting married seemed so obvious, and so contrived. I missed having the surprise in it.
