If Alicia does run for State's Attorney, it sure would create some interesting changes. However, I should think that having the governor's wife run for such a position would be.....weird. However, it does look like they are writing Finn out of the show. If Florrick-Agos goes forward with Diane Lockhart, that may indicate that MJFox's character, Louis Canning, will be sticking around as a more regular cast member. Not sure I'd be a fan of that, as his schtick is only tolerable in smallish doses. I don't think we'd heard the last of Jackie's attitude about whatever Alicia and Peter's relationship has become. Heh. With the emotional confrontation between Cary Agos and Alicia, there will likely be repercussions in their working relationship going forward. Speaking of Cary, it was interesting to see "the other Cary" play such a prominent role tonight after being absent for so long.
Just wanted to add that someone upthread mentioned that there is backstage stuff stopping Kalinda and Alicia scenes, but I'd bet Kalinda will come with Diane to FA, so I guess we shall see how that aspect plays out soon enough.
