A deleted scene from part two showed Sora being returned to the Genii as part of their deal for the nuclear weapons, but this was cut due to time constraints. Being cut, it is unclear if the event occurred or if Sora may still be being held. This is the first appearance of the "Daedalus" class battlecruiser, specifically the first ship of the class, the "Daedalus" itself . It was first mentioned in the "Stargate SG-1" episode "Moebius", which also included a brief image of its schematics. This is also the first episode in which the full given name for Radek Zelenka is revealed. The producers chose "Radek", a fairly common Czech given name, without input from portraying actor David Nykl. At the end of season 1, Rainbow Sun Francks (portrayed Aiden Ford) was disappointed about the evolution of his character, he then asked the producer if they could expand him somehow. The producers agreed and reduced Ford's status to a recurring role so that his story arc would be more important to the "whole" story arc of season 2.
