Other mistake: When Spike is thrown out of the base by Megatron at the end of the episode, Optimus calls him 'Splik'.
Other mistake: At the end of episode 2, Robin escapes from the Visitors into the wilderness. In episode 3, she's seen in an internment camp with no explanation as to how she got there. She is also wearing different clothes. She later escapes the camp along with other resistance members. Then at the beginning of episode 4, she is back alone in the wilderness, wearing the same clothes as at the end of episode 2. My guess is that episode 3 was added as an afterthought. (00:01:30)
Other mistake: When Tubbs and Castillo are talking in the entrance way of the Senator hotel, at the end of their dialogue Philip Michael Thomas makes a very clear gesture with his right hand, which is Don Johnson's cue to finish his phone call in the background and approach the others.
Ground Zero - S4-E14
Other mistake: When Hawke blows up Yahara's plane, we see that the video feed in the holding cell where Locke, Santini, and Rivers are is actually from a 3rd person perspective and that it continues, but according to previous dialogue (and video up to that point) the camera was installed on the plane, so once Hawke blew the plane up, there should have been no more video feed.
