The final scene was the best scene of the series in my opinion because it drastically challenged the central plot of the show...
Nora asks the final question: do you think the departed are in better place? The woman breaks down crying, and says no...that shyt had me shaken...this whole time, all the theories and the Rapture stuff automatically gave the departed a "better place" mythology while we haven't really talked about the flip side: what if they are suffering and struggling wherever they are? What if they were taken for some nefarious purpose?
It makes me think of the 400, 000 plus people that are currently missing in the United States and have not been found (and probably will not) be found...do I think they are in a better place? I have to say no, and that's why this episode's ending was one of the most haunting endings I've ever seen...just something to think on.
