The story of season 4 so far has been OK. It hasn't been my favourite season so far but still highly watchable and enjoyable. However this episode for me didn't really make a lot of sense. Reading the other reviews I was confused as whether I had watched the same episode to them. The episode didn't really seem necessary to the storyline and I don't think it gave me a good insight to the future life of Connor.
I understand that the producers may of tried to do something different or to show the reader another side to the future story, but for me it didn't work well.
I love Nip/Tuck and cannot wait to finish it.
