So I have one observation about the ending:
Spoiler alert if you haven't seen it yet
I have seen a good amount of discussion on what is going on here, and agree with a lot of it, but there is one detail I haven't seen anyone mention (and maybe I missed it somehow) but when she goes out to clean the bodies of the sheriff and his wife don't appear to be out there, but they do show up in the silo feed. Is this just because of what she is seeing in her helmet or are the bodies gone? How true is the feed from the the silo?
