“Now I’ll return the favor with another one of my phenomenally successful multiple choice quizzes, this time pertaining to the fate of a certain MIA island on Lost. We will come to learn that one of the following is true in Lost’s fifth season premiere.
A. The Island moved forward in time.
B. The Island moved backward in time.
C. The Island did not move in time, but it did move in space — to another location on the planet.
D. The Island did not move in time or space — it’s still there, but Dharma tech renders it invisible to the naked eye.”
