some answers..in white!
I think we may just have gotten ourselves a big honking answer last night to a question looming since the beginning of season two: What, exactly, was contained within that massive bunker buried underneath the hatch (i.e. the Swan station), a bunker seemingly made of concrete and lead? Well, it looks like it may have been good ole Jughead, a thermonuclear device capable of emitting a massive electromagnetic pulse; your guess is as good as mine as to how that energy would interact with the time-trippy qualities of the island. (Asst. Prof. Vary extracurricular reference No. 5: I confess to only the most basic knowledge of the Archie comics, but I do know the character of Jughead was always obsessed with food, needing it constantly...like, say, every 108 minutes.) If Juggy wasn't what was buried under the Swan, then, well, crap, it appears there's a rogue H-bomb tucked somewhere underneath the island. And as we learned from last season's finale, you don't show a bomb on a TV show like Lost unless you intend it to go boom.
