I am glad Carly has dragged Olivia into her drama as Olivia now has something to do besides date Dr. Webber. And I agree with both Sam and Carly, why do you need to biopsy Jason's brain while it is swollen. Whatever is there has probably been there a long time and could wait a day or two for the trauma to be a little less life threatening. But then I'm not a doctor. Of course, neither are the people who write this stuff so it is all for maximum effect.
Diane and Alexis night at Jake's is giving a great comic balance to all the drama. Diane should be relieved her divine coat was spared from the storm, forget the shoes. That coat is gorgeous.
Another balance to the stormy night's events is Lucky's trip and flashbacks. It is all really well done.
