What an episode. when the four characters heared the music running up to this finale, i thought it could be rationalised logically, that we would get a cop-out theory... i was wrong. I loved it when Sanders, the presidents aid, Tigh and Chief walked into that room together and they know what and who they are. Everything that they stood for means-nothing now!!! i remember back to the episode where Dean Stockwell is introduced as a priest to help chief, who is having nightmares of killing himself and he jokes "you're not a cylon because i've never seen you at our meetings" Classic episode. i guessed only Sanders to be a cylon but never Tigh or the others!
