Interestingly enough, it's Tory who brings Cally's alienation to an end (being careful to save baby Nicky, who we now know is a human/Cylon hybrid like Hera). Tory seems to be, thus far, the only Secret Cylon who's becoming comfortable with her new identity. Early on she tells Chief that she's beginning to enjoy being open to new possibilities — and we watch, horrified, as she knocks Cally across the airlock with her Cylon super-strength and then blows her out the airlock with nary a second thought.

The look of this episode went a long way toward illustrating the themes. To put it plainly, everyone pretty much looked like hell. Most notable were the dark circles under everyone's eyes, in particular Cally and Kara, who probably looked the worst. What more startling way to experience alienation than to not recognize the face that stares back at you in the mirror? The muffled sound and disorienting visuals surrounding Cally as she prowled the ship looking for her husband went a long way toward making us feel how out of sync she was with her world.

In yet another military decision I don't understand, I was surprised to find both Helo and Gaeta among the crew of the Demetrius. They both hold fairly critical positions on board Galactica, perhaps more so now that Lee is a civilian. Is it wise to have sent them both  on this mission? Will this decision come back to bite Admiral Adama in the ass at some point in the future?

So where did this episode lead? Well, we're now faced with more uncertainty regarding the true nature of the Secret Cylons. Was Tory's ability to flush Cally out the airlock an indication that she was never a very nice person to begin with, or is this a preview of things to come as the quartet's "Cylon natures" begin to seek expression? If it's the latter, can we expect that Tigh's unsettling vision of himself shooting Adama will come to pass? What price will there be to pay if and when Chief finds out that it was Tory who flushed his wife off the ship? What does all of the internal conflict among the Cylons mean for their future relationship to the Colonial fleet? Will unlikely alliances be formed? Will Kara's physical and emotional separation from her crew endanger her mission? And perhaps most interestingly, what can we expect from sentient Centurions and rational Raiders? It's a good show indeed that raises more questions than it answers with every episode.

Was there any light in the darkness at all this time around? Well, in a big shout-out to geeks Star Trek fans everywhere, Cally discovers Chief's Cylon identity by intercepting a note left for him instructing him to meet the others in weapons locker 1701D. (It is, of course, no secret to fans that BSG executive producer Ronald G. Moore was a writer and co-producer on Star Trek: The Next Generation.)
