At the end of my last column, I asked whether the “variable” would prove to be an event that could change everything. The one thing that could have a domino effect on the outcomes of every event that followed. I wondered if this changeable event is what Ben and Widmore have been fighting for control of. After watching “The Variable,” I have to say “yes,” this is what the term is referring to. However, I’m still not so sure whether the variable will actually vary anything according to the mythology of the show.
