They have been very good at making things consistent & tying stuff up (unlike e.g. The X Files), but some stuff - even important stuff - does get "made up as it goes along" (although there is still an arc, just not everything was planned out first like e.g. B5).


The importance of the Final Five, and later their identity, wasn't decided until later, well after they had initially decided that there would be "12 Cylon Models" but only initially show us the Significant Seven.

e.g. When it was later decided that the Chief would be one of the Final Five, the writers suddenly had the problem of his & Cally's child Nicky, who would now be a Cylon/Human hybrid like Hera... except Hera is meant to be *the only hybrid* and has long been deemed vital to the storyarc.

So... they had to "retro-fit" Nicky's parentage (RDM's words) by making Hotdog the biological father, removing the problem of having another Cylon/human hybrid.


So I think it's possible that once they had decided on the FF's backstory & importance, they suddenly realised "oh crap, that screws up the numbering" & created a 13th who would be No.7.


Still, it would be a bit of a red herring if "Daniel" isn't important in some way...
