In the series, did they ever explain why there are only 1 of each of the final fours?
For the purpose of resurrection, all other cylons have multiple empty body shells, and if they want, they have multiple versions of themselves walking around.
As seen in Ellen’s resurrection, there obviously are multiple backup bodies for the final 4 as well? Or is there?
So is the only reason for only 1 copy each Cavil’s doing? That Cavil boxed the rest? Or is the finale 4 incapable of having multiple copies of them around?
