Character mistake: Sometimes in the show, when a Goa'uld or Tok'ra is speaking (as opposed to the host speaking), they will say "my symbiote", such as when facing danger or illness: "my symbiote will protect me" or "my symbiote will heal me." However the Goa'uld and Tok'ra are the symbiote and they should be referring to themselves protecting or healing the host's body.
Emancipation - S1-E4
Character mistake: After trading the pistol for Carter, Jack says "there's only 5 more rounds in that clip." However, the pistol didn't have a clip, it had a magazine, which is completely different. As a member of the Air Force who has been trained in firearms, he would know the difference.
Character mistake: At the beginning of the episode, O'Neill refers to the planet as P3X-989. When he awakes as an android, he says "Welcome to PX3-989." The P3X becomes PX3. (00:03:35)
Character mistake: When Daniel Jackson learns about the fact that his wife, Sha're, has returned with a dormant Gua'uld, he does not take her to Thor's Hammer that got repaired in S2E6. Even though he was with Teal'c, that doesn't pose any issues since he is deliberately exempted from the Hammer.
Touchstone - S2-E14
Character mistake: The team are finding out who could have stolen the weather device from Madrona and find an energy spike at the same time SG2 are on a mission. "But SG2's mission is galaxies away from Madrona" Says Teal'c. At this time the only missions the teams could go on was in our own galaxy and couldn't be galaxies away.
Character mistake: When Hammond and Carter come out of the base, Hammond is told he's been gone 22 hours. Hammond says he's only been gone about 20 minutes. To which Carter says, due to time dilation, time is moving an average of 600% slower and that telling O'Neill to wait 5 minutes would be 6 hours or more. However, 600% is just another way of saying "6 times" and time is slower by about 66 times, so she should have said an average of 6,000%. 5 minutes being 6 hours would be 72 times slower.
Character mistake: In the first scene in the coffee shop, Pete suggests going to the Zoo and Sam tells him there is no zoo in Colorado Springs. Colorado Springs does have a zoo, that was founded in 1926 and has operated continuously since. It is less than 3 miles from the city center and Sam both attended The Air Force Academy, and has lived in the city for at least seven years, so it is inconceivable she wouldn't know it exists. Also her answer appears genuine and not intended to deflect Pete's invitation by lying. (00:04:30)
Character mistake: In newspaper article "Anubis plans to retake Dakara", there's a line that reads "being partially ascended has it's benefits." The word should be "its."
Character mistake: At the end, Vala and Mitchell establish a wormhole and let Teal'c and Jackson know. Almost a minute passes before Teal'c and Jackson get back to the gate and Jackson yells "run" because they need to get through the gate right away. Obviously they're detained, but after being let go, Mitchell says they're sending the iris code now. This is something that should have been done sooner, especially after hearing gunfire, so they could be ready to go through when Teal'c and Jackson arrived.
Suggested correction: OR... after hearing the gunfire maybe it was smarter to wait until they verified that it was Teal'c and Jackson who prevailed. Otherwise, they risked leaving the gate open to a hostile force.
Perhaps they waited, but they still would have sent it when they saw them, which the didn't. And they've never waited like that before.
