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".
Starbuck is promoted to CAG aboard the Pegasus, while Apollo is demoted.
The Cylon ship the fleet is targeting is called a Resurrection ship because it is full of the human emulating Cylons. This ship is necessary because it stays within range of the human fleet so that any Cylon agents who are killed can download their consciousness into their next clone, telling us that there is a maximum range for their downloading ability.
There are 49,604 human survivors.
There are 49,604 survivors in the human fleet, the same number as in the previous episode.
Adama is promoted to the rank of Admiral.
Feeling betrayed by Roslin, Baltar gives Gina the nuclear warhead that he used as part of his Cylon detector.
We learn that Roslin was having an intimate relationship with President Adar before the Cylon attack on the Colonies.
President Roslin is infused with some of the Cylon/Human fetal blood from Sharon in order to cure her cancer.
There are 49,598 Survivors.
189 Days have passed since the initial Cylon attack in the Mini Series.
Continuity: In the final scene, after Kat taunts Starbuck by saying "My cup runneth dry" while drinking from the "Top Gun" stein, Starbuck is seen grabbing the neck of a bottle of ambrosia with her thumb facing down as if she was going to smash it or use the bottle as a club. In the cut immediately following that, she can clearly be seen holding the neck of the bottle "thumb up" as if to pour or drink from it.
In the Season 2.5 DVD version, the fighter shown in the launch tube is now--correctly--a Mark VII Viper.
There is a minor editing goof when Starbuck and Kat launch from the Galactica during the 29th day of operations of the Colonial mining ship Majahual (approximately 45 minutes into the episode). On the flight deck, both are clearly seen in Mark VII Vipers. When we see one of the Vipers in the launch tube, it is a Mark II Viper, the older model.
Caprica Sharon informs Kara that Cylon Raiders can be resurrected, just like the human Cylons are. They retain their memories and experience, thus making them more effective and intelligent fighters.
The guitar music used in the last scene of this episode is "Cavatina", best known as the theme from the 1978 movie The Deer Hunter.
When Admiral Adama asks Lt. Gaeta who "they have" on Cloud Nine, Gaeta reports that Captain Adama, a handful of marines and Starbuck are aboard, but he fails to mention Petty Officer Dualla.
