well that was awfully crappy. A lot if convoluted storytelling with questionable logic,,,I mean if time reset regarding the observers then wouldn't that change the while September distracting walterbate funding the cure,,, I mean Olivia and Peter may never meet. Then couldn't widmark knowing where the child was just go back in time.
I also don't buy the stupid idea of Walter being erased in 2015 it was just writer fiat to create syrupy predicament. And speaking of pointless the trip to the alternate universe was stupid,,,bringing the observers over to lead to possible retribution or an invasion over there. No Nina, no Charlie etc.
and seeing how the plan came into place was just a way to drag out the season. BAD
