Maybe I'm not reading all the posts or I'm not going to the same sites as you guys are, but we're all going on the notion that those four people (Tigh, Chief, Tory and Anders) are cylons? 'Cause from what I saw, the only person who said it out loud was Chief.
Let's take Tigh as the best example. Do Cylons age? How is it possible that Adama has known this guy for some twenty years? I thought the Cylons looked more like the OG Cylons at that time. When they went away, after the Cylon war, they created the human looking 12. Tigh doesn't fit.
Every radio signal, every TV signal, we've ever sent is out there in the cosmos right now. (Remember "Contact?" How the initial message from the other world comes wrapped in the transmission they recieved from us? Footage of Hitler?) Is it possible that the Gallactica resonates this signal, "All Along the Watchtower" and that these four folks are the only one who hear it? Or at least are the only ones to admit it? That it's a radio signal from earth?
Anyway, that's how I'm going to get through the next several months till I get a new episode. Chief is not a cylon and Starbuck is not dead. I'll just keep repeating it over and over.
Chief is not a cylon and Starbuck is not dead.
Chief is not a cylon and Starbuck is not dead.
