As for this episode, I found it to lack the suspense and drive that most Grey's Anatomy episodes tend to hold. It was a relief when George remembered the sexual relations that he had with Izzy the night before. Honestly what girl would want a guy not to remember whether or not they were intimate. However the choice for them to keep it from Callie seems like that is just going to end up in a blow out or the truth being revealed in a later episode which as a viewer would be one great episode. So I'll have to keep my fingers crossed.
Mark Sloan is starting to come out as a more involved and important character. No complaints I'm sure from the lady views of Grey's Anatomy. It will be good to see where him and Addison progress especially with the new chief position.
Finally, Derek and Merideth have been up and down in their relationship throughout the previous episodes and have now hit a plateau where their relationship has been very stable for sometime. Something rocky coming in their future? Guess I'll have to watch some more episodes to see if this puppy dog love will last.
