I wasn't thinking of Helo's story ("The Woman King") when I mentioned the plot twists but the way the whole human/Cylon thing is eventually resolved. I won't spoil it for you but I will say I was disappointed.
As I think on it, the episode is kinda despicable in the way it fleshes out the paranoid rationalization for genocide--here it really is a war for survival; no, not a war, an animalistic struggle
. But then, much as I love DS9, I was always creeped out by how easily the Dominion can be read as an allegory for the Ku Klux Klan/Neo-Nazi fantasy of Zionist global control. Here we have a species supremely skilled at disappearing into host populations (cf. Jewish assimilation in Europe) who, after being clobbered one two many times, retreat to their home-world (cf. Israel nee Palestine after the Holocaust) and engineer a proxy force of quisling humanoids (cf. white race-traitors who do the bidding of their evil Jewish overlords) and malignant, hyper-violent sub-humans who are addicted to a white narcotic (cf. the American bogey-man of the crack addicted gangsta). I doubt this model was in anyone's conscious mind when the idea of the Dominion was mooted and developed but it's eerie how close the allegory maps and how potent such an evil paranoid fantasy is even among those of us who should know better.
