And of course the most obvious: Once Baltar realizes Boomer is a Cylon, why doesn't he do the immediate "you're the humaniest human ever " stall and then run to Adama and tip him off? Kind of like "Lord of the Rings," where time is of essence and, with the Ringwraiths devastated and winter fast approaching, they fuck off for 2 months in Rivendell while everyone fucks around. Why not Gandalf ending with "I was rescued from Saruman by eagles" didn't someone say "Hey, why not give the Ring to an eagle, have the fucker fly off and drop it into Mt. Doom?" Especially given that the eagles play into the finale. But that would derail the story.
This is the thing about the whole "God did it" and the episode where Head Six(?) tries to frame Baltar for treason: Ghost stories. Jason. Freddie. We give the incredibility a pass in order to enjoy the story. "Got did it" is a literal deus ex machina the writers use to keep the story moving. And anyone who argues it was a cop-out in S4 forgets they were using it as a key story point early in S1.
