When Ginn drops the Destiny out of FTL as a "distraction" to tell the crew what's happening with Rush in the simulation, this *should* have caused a momentary disconnection for anyone using the Long Distance Communication Stones. Given that these were being used against involuntary participants as part of a covert infiltration operation, this should have caused the failure of the Langara mission.
Woolsey says that "SG-1 teams four and five" will gate to Langara, but this makes no sense. SG-1 is shorthand for SG team one; the other two would be referred to as "SG teams four and five".
