The Man with Nine Lives - S1-E17
Plot hole: Considering Galactica's mission of protecting the entire fleet, she wouldn't risk having recruits brought aboard that haven't been through a security screening already, especially a pair from a known warrior-like race, both of whom are wearing weapons openly. Nor would they be guarded by a crewman who willingly answers classified questions about locations of decorated Warriors posed by total strangers. Yet all of these gross security oversights occur in this one episode.
