What Happens: A fetus floats to the top of an hourglass. Slowly, it begins to turn black, and we pan down to see what's in the other end of the hourglass: a rotting heart.
What It Could Mean: This, presumably, is the beginning of the season. The heart of humanity has grown rotten. Slowly, we are poisoning the earth and ourselves. To me, this seems like a commentary of the state of affairs, a moment of reckoning that signifies why the apocalypse begins: we've brought it upon ourselves, and it's time for a cleanse.
