OK, now they have officially gotten me confused. When they found the dead person, they first say - at least to my ears - that it was Berglind who was killed.
Then Annie says it was Heather who was the dead person.
But the person's appearance clearly resembles the former person mentioned. The girl had blonde hair more of the shade of Berglind's than Heather's and was much longer than Heather's.
So - now we wonder if any of them (besides maybe George) have escaped.
The tower bit was a bit obvious as far as what was going to happen, and it was a bit implausible that Johnny would be trying to carry Joyce (Carolina) to the cabin after what happened to him to begin with.
Some parts of this are now reading a bit "Jurassic Park" to me with the suspense and the footprints, but that is a good thing.
I will admit if what we're seeing is correct, I will miss Annie and admittedly Esther.
