Someone's hit the switch again, up in the control room, out in the guard booth, and the Garden of Eden sign is all lit up once more. This time it plays out in a slightly different way... either that, or our attention span is longer now, and we get to see more of its rotation. And for the first time we see a strange word, CAVE, start to pop in. This happens twice. Then the sign tidies itself, pretending that nothing happened.
