Other mistake: When O'Neill first goes to visit Teal'c in his cell the symbol of Apophis on Teal'c's head is upside down.
Continuity mistake: As the prisoner line is moving, it shows Xev with a guy in front of her who's very skinny and wearing a black hat. When they reach the Holo Court the guy in front of her is suddenly a different guy, who's fatter and has no hat on. (00:22:35 - 00:23:15)
