I enjoyed this episode. I especially enjoyed Baltar walking into the room, not knowing everyone else can see #6. However I find it extremely difficult to look past a silly bit of plot short-cutting that was basically the nucleus of the whole episode.
We are all aware that Cylons can take human form. So then how is a video of someone doing something even credible at this point? And, if you were Baltar, wouldn't your first response to this *proof* be to say "It's not me, it must be a Cylon! I mean, remember how they can look like humans now??". ESPECIALLY when the tape is supposed to be of someone taking a bomb into a defense mainframe or whatever, which helps the Cylons directly.
I just couldn't really understand how this massive continuity error could have seen the light of day. Change the *proof* from a video to something else, and my opinion of the episode changes dramatically.
