After Jonas takes away Carter's pistol, we see several cuts showing Carter still holding the gun.
[At around 05 minutes] Connor takes SG1 to the remains of Frakes, who was shot, then burned by pouring lamp oil and lighting with a torch. Only a pile of ash and dog tags remain. Such a fire would be nowhere near hot enough to reduce the body to ash, which would require a much greater accelerant in large quantity and/or an industrial crematory furnace. They should've found a charred body.
During one of the panning shots of workers in the quarry, one worker can be seen in center screen engaging in a chopping action but making no contact with the rocks.
As Jonas escorts Capt. Carter out to show her his temple being built, one of the hut's guards can be seen with an athletic supporter strap exposed from beneath the cloth tied around his waist (likely worn to prevent a "wardrobe malfunction").
When Teal'c taps his staff weapon on the floor, where the second device is found, you can clearly see that the weapon doesn't touch the ground.
Jamala has probably never used a weapon before, let alone modern technology, yet he shoots Lieutenant Baker with his first attempt.
Daniel says of the biblical Abraham that he was "believed to be the father of man." This is incorrect; Abraham was the father of the nation of Israel, not the entire human race. With Daniel's knowledge of ancient civilizations, he should know better than to make this mistake.
At one point, Teal'c refers to Daniel as such instead of "Daniel Jackson".
When O'Neill changes clothes with Jamala you can see the SG1 patch has a white "1" on it. The "1" on O'Neills patch used to be black and not white in this episode.
