In the mid-season “finale” of Battlestar Galactica, entitled “Revelations“, there were indeed amazing revelations made. The identities of four of the final five become known to Cylons and humans alike. And as a result, both groups find Earth. It is a wasteland, still tainted by radiation, the landscape littered with the ruins of a civilization. Presumably our civilization, although who knows. Perhaps the humans and Cylons who’ve just arrived will make a fresh start, and they will be the ones who give birth to our civilization.
The most powerful moment in the episode is when D’Anna begins speaking those words we’ve all heard so many times in the series: “All this has happened before…” but Lee Adama interrupts her and says “…but it doesn’t have to happen again.” It is possible, he emphasizes, to choose a different path. Perhaps that will be the key to the founding of a new civilization, including humans and Cylons, on Earth, one that perhaps will break the cycle. Nevertheless, some “higher power” has been leading both sides to Earth, and we have yet to learn more about the nature of this “God”. “Something’s orchestrating this for a purpose“.
The biggest clue of the episode? D’Anna stated at one point that there are four of the final five Cylons in the human fleet. The meaning is obvious. One of them was there on the Base star!
