To me it was kind of a foreboding, or foreshawdowing, sense of things to come in the series, and its very early on in the series as well, its when Locke has started to apprentice Boone, which ultimately leads to his demise, and they are out digging around in the hatch when everyone thinks they are hunting for boar.
