1. All the revelation scenes were good and meaty, but the Tigh/Adama scene was a particular highlight.
2. The trouble is, I can't see a story about representatives of a society from across the galaxy searching for Earth and then finding it, only to discover it's a radioactive wasteland, without thinking of
Isaac Asimov. Which means that clearly the next logical thing for the crew to do is go and have a nosy about on the moon.
3. In all seriousness, I think the odds of the final cylon being some kind of architect figure who's been mistaken for god by various parties are quite high at this point. Whether (s)he will turn out to look like anyone we already know is anybody's guess.
