There are 49,604 human survivors.
Before the confrontation between the Galactica and the Pegasus, Pegasus can be seen to be directly "above" Galactica in the fleet, yet during the attack - only moments later - it is much further away.
The Pegasus is a Mercury-class battlestar, a more advanced type of vessel than the Galactica.
With the arrival of the Pegasus, there are now 49,605 survivors in the fleet.
With the arrival of Admiral Cain, Adama is no longer in command of the Colonial Fleet.
It was Director Michael Rymer's idea to have Cally and the other woman walk out of the room where the Pegasus crew members were boasting about having raped Gina.
Ronald Moore explains in his "podcast" commentary that the sexual assault scene was filmed just as it was written. He says, however, that they also filmed a version of the scene where Lt. Thorne has already begun raping Sharon. There was a lot of debate among the writers about which version to use, but they decided to go with the one where Helo and Tyrol are able to avert the sexual assault.
The scenes onboard the Pegasus were shot on sets originally constructed for a failed pilot for a new, re-imagined Lost In Space TV series.
The Pegasus Deck Chief, Laird, designed the DDG-62 engine used in the Blackbird.
Admiral Cain is from Tauron.
Baltar makes a faux pas, calling Cain a Commander instead of an Admiral, after which she corrects him. The original series' Cain was Commander Cain.
In the original Battlestar Galactica, the Galactica came across the Battlestar Pegasus, which had been sent away to fight at Gamoray before the great Cylon attack. The Pegasus was under the command of Commander Cain. After a pitched battle with three basestars under the command of Baltar, it was never confirmed if the Pegasus was destroyed or not. Adama simply says that if Cain survived, he would maintain radio silence to protect the fleet. The story was presented in a two-part episode, "The Living Legend".
Though she is listed in the opening credits, Tricia Helfer does not appear in this episode.
Number of Survivors: 47,853
The Viper Tyrol has to scrap is numbered "289."
Tigh arranges for Tyrol to get some obsolete DDG-62 engines stored on the Baal Pakal.
Tyrol's fighter is called The Blackbird and is christened "Laura" for President Roslin. It is the first new fighter fabricated in the fleet.
Producer David Eick had the director, Robert Young, do one take of the last scene where Lucy Lawless used her American accent, to speak to the other Cylons, instead of her normal one, adding a new level to the character. They used her American accent in the scene.
D'anna Biers is the sixth Human Cylon model to be revealed.
Gaeta's first name is Felix.
