How did Asa end up under the floorboards?
I felt like this was an important detail that they completely dropped the ball on.
The last time we see Asa alive is in a storm one a snowmobile. Then we see flashbacks of that snowmobile down in a crevasse in the glacier and everyone assumes she's down below where no one can get to her body. But then her body ends up under the floorboards of the research station's shed.
How did it get there?
