Widmore's victim, blindfolded. ("The Other Woman")

Blindfolds were used multiple times on Lost, most commonly by the Others, to keep their location mysterious and to conceal other facts from the survivors. These commonly took the form of a hood or bag placed over the victim's head, rather than a traditional piece of folded cloth. Not only did bags make more sense in the context of the story (e.g., impromptu nature of kidnapping, scarcity of resources), but also hoods enhanced suspense by completely disguising the victim's face.
