V: The Final Battle: Part 2 (2 Hrs) - S1-E4
Plot hole: During the raid on the pumping station, Elias overpowers a Visitor guard and throws him off the catwalk - into a hall full of workers, engineers, and even more guards. Strange that no one notices.
Revealing mistake: When Kyle, Elizabeth and Robin are in the truck being chased by Mr. Chiang, in all the outside shots of the truck it is very easy to see that all three of them have been replaced by doubles. (00:09:05)
