I loved this episode holy crap. It's great seeing how the four are changing and acting differently and stuff. The real question in the episode for me is why did the Cylons retreat when they scanned Anders?

The entire opening was incredible. I was holding my breath as well And then that bit where (SPOILER)Tigh shoots Adama! Holy crap that was so well done that my expectation that it was some imagination thing was completely quashed.

Seeing as we've speculated about damned near every single person, and they've shown that somehow even people as old as and unlikely as Tigh can be Cylons, I'd say they'll have a bit of trouble making the final reveal truly dramatic and unexpected. Still, high hopes!
