Ok, so Number Three (aka D'Anna Biers) saw the face of one of the final five and said she was sorry and had no idea.
I believe one of the final five is Samuel Anders..
Why: No known siblings, family
Was conveniently in the mountains when the attacks occurred.
Encountered model 3 in the parking garage, but 6 and 8 let him escape.
Is drawn to Star Buck continually even though she's been cheating on him.
Recovered quickly from "having the flu" down on New Caprica enough to play some pyramid.
Looks like one of the final five from the production still taken (and yes I know they mention it might not be a true depiction of the final five.)
I actually think it's Doc Cottle. On New Caprica he pointed out that he felt compelled to save both Cylon and Human lives. That was part of an odd scene between him and 3 that never seemed to have too much purpose at the time.
Adama (either of them), Dee and even President Roslyn perhaps... Kara is also a possibility I guess but we'll know that after this weekend. :-) Also, let's not forget Baltar! For sure the 5 remaining cylons must be integral to the story, I don't think they'd be secondary characters.
Tigh's wife would have had to have been embedded way early, we aren't sure if the cylons infiltrated that far in advance.
If the final five are sleepers, what is so different about them that they other cylons don't discuss them? Why don't we see them on the ships? I figure they could as easily be renegades, or deformed ... or ...
Anyway, Anders is a good bet; Dualla would be so much like Sharon, plot-wise.
Oh yeah and I forgot about "Mr Gaeta" whose name sounds so much like "Mr Data" when the Commander/Admiral or Saul ask him for information. Are the creators just fracking with us or is that a hint?
Well we find out at the end of season three that the cheif,anders, the colonel and Roslins aid are all cylons but we have to wait till season four for the final cylon to be revealed. There are bets though that Roslin or either adamas are in there but really I think it is going to be someone we never thought about
Apollo is one of the final five Cylons, he just doesn't know it yet. Remember back when the president was told that Adama was a Cylon. Everyone naturally thought of the old man, but I think it was Lee Adama who he was speaking of. Look at all of the injuries he has bounced back from. For being human, Lee bounces back pretty good. I guess we will find out soon when the final season airs.
Oh yeah I almost forgot, death to all humans. By your command!
