I just re-watched the finale.....Loremaster wrote:As far as I can recall, it was never established that all of the Basestars were in orbit of the Singularity.
Zahir, it does matter. If it's accepted that the rebel cylons (Centurions) could 'live' on, any of Cavil's surviving Basestars would also contain centurions. Now the difference between them is that the rebels were altered, but the remaining Cavils may have been forced to improve their own to help their race survive - skinjobs or not.
I think there's an interesting story to tell about the rebel Centurions who left on the Basestar, but I can't see how there are any other surviving Cylons.
