I've wondered about the Lords of Kobol, the 13 tribes, and whether there was a missing Cylon. At a guess, would the jealous god be anything to do with the 13th tribe and the Cylons, and Baltar is one of two final Cylons? Could the block on the 7 Cylons be put there by the jealous god?

Back in the early days Ron said the fleet was just being hounded by the Cylons. It was only when the audience started taking an interest did he develop their characters and world. The pit-stop at New Caprica probably came about because of that, so the last series probably shapes up differently to what it would've been.

I'm going to throw some dice here and suggest the original plan would've been a straight chase. The Final Five are, perhaps, ancient Cylons who are pulling a Foundation style psychohistory nudging of humanity towards transcendance but the 13th Cylon has a few control issues. Now, the humanising of the 7 Cylons created a new dynamic that's been folded in and the Hera plotline is symbolic of a shared transcendence.

Now, I reckon, Baltar might be revealed as the Final Cylon but not the Final Final Cylon. Instead of a fake death like Starbuck got dealt with we'll get a fake ascension. I'm starting to handwave like a helicopter here so I'll back off and just see if it survives a shakedown as plausable theory.
