Revealing mistake: As the gang drives up to the space-ship diner, cars are whizzing by in the background. When they are driving to the base there's also a clip of a fire truck going down the highway in the distance.
Factual error: In scenes from the oil rig there are shots that show the shore line. This oil rig is supposed to be offshore of Louisiana. However, mountains can be seen in the shots of the shoreline. There are no mountains in Louisiana.

Single Point of Failure - S1-E2
Revealing mistake: Walter accesses code on the sick girl's laptop to trace the source of the virus - aside from the fact that the code comes straight up a fraction of a second after his hands even touch the keyboard, the code displayed in the black window is for a set of traffic lights, with lines like "Walk/Dont_Walk" and "Green_Arrow/Yellow_Slow." (00:08:10)
Continuity mistake: During the street scenes it appears to be fall with leaves on the ground, grass green and streets and sidewalks dry. However, when police raid the park worker's house there is snow on the house roof and on the ground. When the police stake out the same house, there is no snow on the house roof or ground. (00:36:00 - 00:41:00)
Continuity mistake: When Bauer walks up the stairs in front of Waterloo station, the clock on the building is displaying 1:50pm, however we are only about 8 minutes into the episode. (00:07:50)
The Legend of Curtis Ballard - S2-E3
Factual error: In the first flashback scene of Ballard serving a Mormon mission in Lithuania, he laments that he has been on his mission for 18 months and has yet to baptize a single person. In a later flashback scene when he and his companion are visiting the prostitutes, he states that he and his companion are 19 years old and they should be in college, going to parties, getting drunk, getting laid, etc. Instead of serving missions. These scenes take place in 1991, at which time young men did not serve missions for the Mormon church until after they turned 19, so if Ballard had already been on his mission for 18 months, then he should have been at least 20 years old, and closely approaching 21.
Twilight of the Apprentice - S2-E20
Continuity mistake: Near the end when Ahsoka runs at Vader, for a split second when he turns around the part of his mask yet to be sliced off is already missing.
Delta Force - S1-E8
Factual error: Chip-augmented federal agent Gabriel Vaughn is chasing a former Delta Force comrade, now suspected of being a hired assassin in Bolivia. He catches up to the man, telling him to freeze because he's standing in a minefield. Vaughn says the field was planted by "Pinochet," which is wrong, since the episode takes place in Bolivia, and General Augusto Pinochet was the military dictator of Chile. Earlier in the episode, Vaughn is asked what happened between him and his former close friend, and he refers to an incident in Fallujah. But flashbacks of the incident show the two men in Afghanistan in 2006. Fallujah is in Iraq. (00:37:00)
Continuity mistake: When Elizabeth starts weeping, her bodysuit is torn above her left breast with a single tear. Post-credits Meliodas asks her to join him; now that torn spot is split in two - the first time the bit of fabric that separates the two spaces was already severed. (00:17:40 - 00:22:30)
