Revealing mistake: When TC says "Sometimes I HATE being right" as he ends up in a shootout as he feared, the close-up is mirrored so he can be shown sitting closer to the camera. The hat's letters are backwards, of course. (00:45:30)
Continuity mistake: When Rick throws himself at the bad guys realizing the pistol is empty, the light of the scene changes entirely. (00:46:15)
Revealing mistake: Throughout the episode, the makeup used to age Elisha Cook Jr. is not of the highest quality, and seems about to fall off his face in the dinner scene.
Other mistake: The bad guy in the control room gets some overhead shots of the camera that point down significantly more than the rest, but in close-ups we never see the camera alter its tilt, merely the direction it spins in, clockwise or counter.
