Wow! "In Sickness" was a very impressive episode for Julianna Margulies and should be contention for the episode she sends for the Emmys. Balancing Alicia's personal life and her legal case, the episode excels in all areas and provides the momentum to bring us into the last two episodes of the season with several thorny issues to resolve.
The core of the episode is that Alicia refuses to accept anything Peter has to say about his past transgression with Kalinda and boots him out. Unreasonable? I'd say so, especially when she argues, during the case, that the client's previous actions should have no bearing on her current health issues and needs. If the patient should be given the liver--in a situation with limited resources--despite her past, then perhaps Alicia should not be so harsh. But then again, the situations are different, so there are other ways to look at things.
Looking ahead, there is plenty that gets developed for future episodes. Peter seems to like the idea that Cary competed with Alicia, the family will come under close scrutiny, and the biggest elephant in the room, Will, is there for Alicia.
Score: 9.2/10
