Epiphanies - S2-E13
Factual error: Early in the episode a damaged Viper makes its way back to Galactica with its port-side gun trailing smoke as if in an atmosphere. But in a vacuum, the smoke wouldn't trail. It would build upon itself much the way shaving foam does when slowly leaking from a damaged can, unless the ship changed course and/or speed and then the smoke would appear to do the opposite - ship turns right, smoke moves off to the left because it remains on its original course regardless of what the ship does. The gun is not propelling the smoke rearward. The ammo inside is simply burning. (00:05:15)
Answer: The original BSG has something of a complex version history. Several versions exist, but the rationale behind what you're referring to is as follows. BSG, before anything else, was a TV series - the 'pilot episode' was a three-part tale called "Saga of a Star World". In that three-parter, a last-minute alteration to the script meant that Baltar was ultimately spared execution, because Glen A. Larson, the series producer, decided that he liked the Baltar character enough to keep him around for the rest of the series. The theatrical version, which was edited down from the three-parter and was shown in some countries before the US TV broadcast, lost quite a number of scenes, including the one where Baltar is spared. The real continuity of the series can only be found in the TV version - the movies, all of which were created by editing together existing episodes, miss out scenes leading to such apparent continuity errors.
