The Living Legend (1) - S1-E12
Plot hole: Galactica's sensors detect a second Battlestar, Pegasus- a shock to everyone aboard. Then its commander, Cain, speaks with Adama via video hookup, and announces that he'll be arriving at Galactica momentarily. Yet he arrives in a Galactica shuttle, marked "GAL 356", which hasn't been sent to go get him since they only just now discovered Pegasus exists. Even worse, this is the same shuttle destroyed several episodes ago when it crashed on Ice Planet Zero. (00:10:55)
