I think I have already figured out how the show ends. Nancy got shot in the head just as before but everything we are seeing is what her dreams would be in the long run while she is sitting in coma. Nancy never woke back up from the gun shot. All were seeing is here dream of a good life in a coma. And how they say they bring everyone back from previous seasons is at the end you realize you are at her funeral and everyone she knew is there. Plus they said its bitter sweet... Nancy in a coma is happy because she is making other people happy. Everyone else can now do what they really want to without Nancy screwing things up, because they have said multiple times thats what she does. It also explains all of dugsweird looking under the blanket to see Nancy naked because thats what she things he would do.
