I have to say this show has grown on me and I loved the season ending revelations. The title of the episode was "There Is More Than One of Everything" and boy did it deliver on that promise. I figured out one of the big reveals but it was still shocking and the final image of episode just floored me.
I'll have to give it to Abrams the show has matured and really come into its own. I'm officially hooked. http://io9.com/5252731/is-there-more-than-one-final-episode-for-fringe
