I didn't like the 1701D reference. Funny when you first see it, but it distracted from a very important scene.
I'm surprised they killed Cally so quickly, I would've expected them to keep her around for a few episodes yet to play out her reaction to Tyrol being a Cylon, but they condensed it into that very nicely done montage type scene. I'm guessing they didn't have a huge blowout between Cally and Tyrol so they could still do that in the inevitable scene when Kara finds out what Anders really is.
Actually, mentioning Kara, I thought at first she was just angry and lying when she told Anders that she only married him because he was safe, but looking back she really was telling the truth, eh? BITCH!! Although the only danger with marrying Apollo would have been that they'd break up a billion times and everyone would stop watching the show.
Oh and it definitely looks like the ship of lights Gods/aliens are on their way if Kara's painting and that comet are what they look like.
Also, the Cylon stuff is confusing, somebody make a bloody flow chart?!?!
