Goof: When Weir and Sheppard enter her office to question Ladon [twelve minutes into the episode], we see there is a guard at the door. They walk in and face Ladon, who has two other guards behind him. When the camera focuses on the leaders again, over Ladon's shoulder, we can just make out the shoulder of Guard #1 in the far left corner, but not directly beside the leaders. As the camera tightens on Weir, when she asks what Ladon wants in exchange for the ZPM, we see that Sheppard is no longer at her side, and Guard #1 is now standing directly beside and a little behind her. Yet in the next wider shot, he has vanished and Sheppard is again at her elbow. During the conversation between Weir and Ladon, Guard #1 moves from the corner, then to behind Sheppard and ends up on the right side of the room. It is not mere angle change, his position has changed. We flash to a quick shot of Atlantis with ominous music for a moment; upon our return to the room, Guard #1 is no longer on the right side next to the door, where we saw him last, he is standing near the middle of the glass wall. The camera zooms in on Ladon for a moment; when it returns to Weir and Sheppard, the same guard has once again hopped to the right, near the door once more.
