#1 is Patrick McGoohan.
(My entry in the monthly "Most Obscure Reference" contest.)
As utterly gimmicky, out-of-your-***, and shark-jumpy as it is, making Tigh a Cylon at least explains D'Anna's apology to the Cylon-of-Light: "Forgive me" as in, "Gee, sorry we gouged out your eyeball!"
Of course that doesn't explain how Tigh, who fought in the war
before the toasters "evolved" into human form, could be a Cylon at all, let alone one of the "final" five. Unless he was replaced, of course, and that would imply the Cylons could download human minds (see below), which they apparently didn't do on New Caprica. It also implies the Cylons can't tell humans and Cylons apart any more than humans can.
That also explains why the Cylons aren't interested in the Chief's baby, not knowing he's a Cylon. However, that raises the question of Cylon reproduction again; if "love" is the missing ingredient, and since both Sharon 1 and the Chief have been shown to have it, and even did the nasty together pre-series, then why wouldn't they be capable of reproducing?
Never mind. The show is so full of plot holes that another makes no difference.
I agree with AT's thoughts way back in November that Baltar is probably a Cylon, and perhaps the #1 Cylon. Computers do what they're told, no more & no less, so (in the real world, anyway) if even "sentient" robots rebel, they've been subverted by a human. That human may have started the rebellion, designed the humanoid Cylons, and then achieved immortality by transferring his mind to the "Baltar" model. The Caprica Six in his head may be #1's way of guiding his "clone".
As for next season, I predict the "Space Faeries" who resurrected Kara (did anyone on this board
really think she was dead?) lured the Cylon ships to the nebula, caused the power outage (which hit the Cylons, too), and will now destroy them easily since their jump drives also have to "spin up" again, just like the Colonials'.
Either that, or Kara was found by Lorien, from Babylon 5:
Kara: "Hi, Lee."
Lee: "I thought you were dead."
Kara: "I was dead. I'm better now."
