The words to the William Butler Yeats poem kept running through my head today as I pondered last night’s installment of BSG.

“Things fall apart; the centre cannot hold”

Since the discovery that Earth was a complete ruin, everyone in the fleet has been on edge. We saw that last week, but their inability to move onto the next step – i.e., finding a new place to live – combined with the now-unnecessary alliance with the Six faction of the Cylons and the threat of the Cavil faction still being out there has proven to be too much for anyone to handle.

Baltar has gone from preaching the word of the One True God to berating any god that would punish its followers for no reason. He basically has his followers good and riled up, with no riot to attend. At least Tyrol attacking Hot Dog relieved some of the crowd’s pent-up rage.

Will Baltar’s followers become the footsoldiers in Tom Zarek/Felix Gaeta’s revolution?

I honestly didn’t think Gaeta had it in him. But after being reviled for working for Baltar on New Caprica and losing his leg because he had to wait for Starbuck to return (and she was married to a Cylon, etc.) and almost being airlocked by two Cylons and Starbuck, he isn’t about to roll over and let Cylon have ANY say in the fleet.

His throwing in with Zarek isn’t all that shocking. But because Roslin has been MIA since Earth, Zarek’s had a bully pulpit from which to seize the ring of leadership and shut down any dissenting voices (Lee). There’s going to be a civilian v. military showdown, and nothing’s certain as to who’s gonna win.

On the one hand, you have to pull for the civilians, because in the real world, we know how well military coups work out. On the other hand, because this is television, we know that Adama’s right and is more likely to have the best interest of everyone involved and should emerge victorious. Should. Doesn’t mean he will.

As for the show’s mythology, we actually learned a couple of interesting things:

• Hera, the human/Cylon hybrid, truly is the only human/Cylon hybrid. Nicholas, son of Tyrol/Callie, isn’t actually Tyrol’s son. Who knew Callie was sleeping around? Certainly not Tyrol. That knowledge, however, certainly colors her behavior toward Tyrol in the weeks before her death. Was she regretting that she married Galen instead of Hot Dog?

• The Cylons actually can reproduce, but perhaps only the Earth Cylons and the new Cylons. Good thing, seeing as the Resurrection Hub is gone. And, I wonder, is Six based on the old-school Ellen Cylon?

And a couple of questions:

• How come the Cylons can’t build a new Resurrection Hub? This just occurred to me now.

• Why is Sharon a model 8? Why was model 7 skipped? That’s driven me crazy for years now. Will that question ever be answered?
