We can relax - not going to happen. Now that would ruin the saga.
I keep asking myself - so now we have 12 Tribes of humans and a 13th Tribe of FF type Cylons? What would seem to them, especially the humans, to be god like Lords?
The only workable within the context of this show idea that I come up with is S7 (now S8) type Cylons. Even without resurrection tech, they would seem god like. Sort of immortal, great strength and intelligence.
So is the cycle that somehow the FF type Cylons vanish from the picture (killed or leave) and do not accomplish establishing peace between the humans and all of the human created (and improved upon by the FF) Cylons?
With the FF out of the way, do the S8 Cylons (or better stated, some of them - the Cavil faction) first enslave the remaining humans (and terminate or co-opt the rebels of their own kind) and eventually settle into a god/supplicant society - on “Kobol”? - until:
-
The humans create FF type Cylons - which does make the S8 type too pleased. So the FF type HAVE to leave - Kobol.
-
2,000 years later the humans through one means or another break free of the Lords, etc.
That would make for a pretty complete cycle. And, if on Earth those “Cylons” created metallic Cylons, which revolt, you would sort of have a cycle within a cycle.
None of which explains the importance of Hera - unless the cycle is broken by her mere survival (and propogation) as a human/S8 hybrid.
