So, Navarro died, right?
She had the same issue as her sister (and mom?), and chose to walk into the afterlife
And when Danvers said to her "If you go out there, make sure you come back" she was referring to her spirit returning as a ghost
Was that anyone else's takeaway from the ending?
Also, the Tsalal facility seems to have been built atop a hill, yet, less than 50 yards outside their door is a body of water for Danvers to fall through...
Jodie Foster can't weigh more than 100lbs, but we're to believe that on Dec. 31st there's a body of water in Alaska that isn't frozen over enough to support her weight?
