Last Sunday's Galactica.
OK--need some help here from fellow BG heads, and I know there are a lot of you.
Specifically, guesses as to the veiled Cylon that Number 3 saw.
There was a clue--Number 3 apologizes to the one she speaks to. That suggests that it is one of the "humans" the Cylons have been trying to pursue to extinction.
My theory? It is Lee Adama.
Bear with me:
(1) Remember Leoben's claim to Roslin that "Adama is a Cylon."
(2) But...he note that he just said "Adama," leaving Roslin with the impression that it is the Admiral he's talking about. And Leoben is deliberately discursive and misleading, weaving the truth around deception.
(3) More evidence, from the miniseries: he takes the longest to recover from the pulse generator overload on Colonial One. Sure, he's the closest--but the distance difference is, for all intents and purposes, irrelevant.
(4) He is able to navigate without difficulty through the Cylon conveyor tunnel during the "Hand of God" battle at the tylium asteriod.
Any other theories?
