I've just watched this episode and I can say that a good (and surprising) ending. First of all, a multitasking House (finding a survivor under the building while trying to solve the problem of crane operator) was same with the same annoying, cool but inspiring way. As the building collapsed, House was collapsing in his own life while Cuddy and Wilson is moving on. There was no gigs like using electro shock to find out what happened to Wilson's girlfriend or solving a case while hallucinating because of his illness and Viacoding, etc. But, he is sharp enough to solve the puzzle of the survivor girl and crane operator he was collapsing while trying to solve the puzzle of his life. By the way, the final of the episode was makes this episode one of the best episode of House M.D.
While I was watching, I thought that new season will be a return to Season 4 or 5 but if this show will continue a new show is waiting for us. This will be interesting to watch. A new Dr. House with a new life. I don't want give any spoiler as possible but last 3 minutes of this episode is nearly astonishing ans shocking.
