Johnny could use a change of clothing, I'm tired of looking at the dried blood on his jacket. Aren't any of them interested in looking in the lockers? At least Carolina/Joyce had the sense to take the snow boots off the dead people. And why didn't Sam and Johnny at least try the keys on the key ring to see if the key to the plow was on there. They don't think things through very well that's for sure.
**But the one thing that sticks in my craw the most with this episode is that NO ONE let the poor falcon out of the cage. Poor thing will starve to death now that all the research people are dead .
