The first episode showed the Others collecting the dead. A few episodes later it’s revealed that they don’t kill, but are perfectly fine consuming already dead organisms.
Helen’s corpse is a recurring reminder up until this episode to the point that Carol has to bury it—an act we never see the Others do, so the popular theory right now is that the bodies are probably consumed. I keep coming back to my Aquamation theory because of the result of the contents in the milk cartons and now also because of the previous energy conservation efforts. Aquamation takes a fair bit of energy to heat the bodies that get processed, and doing it to nearly a billion people would be no small feat.
The powdered substance found in the dog food bags are likely crushed bones (basically calcium) or crystallized aquamated people used to fertilize or be consumed.
Of course Carol is shocked to see something, but we’ll need to wait and see what exactly.
Whether or not I’m onto something it’s an illuminating look into the funerary world and the alternatives that exist to embalming and a casket.
































Hmm dehydrated brains might need a second take if she were searching in a dark freezer. I like it.
