Okay - more self-confession time. This is one I tried to explain to my wife once. Cuz, you know, Ben tells Locke:
"Help yourself to the chicken -- sorry, I ate most of the dark meat myself."
He's really talking about the island. You know, 'cuz he's harnessed the dark powers of the island.
And then Locke said they were out of eggs.
And then Locke was killing another chicken.
It makes sense, right?
Island = Chicken.
