Continuity errors/Stargate SG-1
Retroactive continuity
- Walter Harriman's name has evolved during the series. First, Gary Jones was simply credited as "Technician". Then, "Davis"' name appeared on his tag name. After, the full name "Norman Davis" is visible several times. And then, in "2010", Jack O'Neill is calling him "Walter" (impro of Richard Dean Anderson). And at last, in "Avalon", Part 1, he is "officially" introducing himself as "Walter Harriman" to lieutenant Colonel Cameron Mitchell when the latter is coming for the first time in Stargate Command.
- Kawalsky's rank is changing depending of his outfit; on his combat fatigues, we can see Captain insignas, and on his class A uniforme, we can see Major insignas. He is called Major by Major General George Hammond, and later by Senator Robert Kinsey (SG1: "Politics").
- Weterings states to the guards who are taking her in the Chulak palace implantation room and to Teal'c that she is a Sergeant of the United States Air Force. Yet, at the beginning of the episode, we can clearly see Senior Airman insignas on her fatigues' sleeves.
