I just want to make a statement to everyone who has read or come up with theories about the Light. I've seen so many theories about how the Smoke Monster is the Light, or how MIB corrupted the Light and became the Smoke Monster,...! Everyone seems to be forgetting how the Light still exists to this day in the Orchid. The Light is still there, MIB may have become part of it, but it isn't all gone.
I would also like to point out that the ice in the Orchid cave is probably due to the water MIB said he would mix with the Light.
