Continuity mistake: On the tombstone in the previous episode, Michael's date of death is 11.4.2005. But in this episode, when Linc goes to the graveyard to visit Michael's grave, his date of death is 11.4.2010. It is also a different grave from the original, as the original was in South America beside the beach, and here we are led to believe it is in New York. (00:50:50)
Other mistake: At the start, it's nighttime when the unsub hides in the house of the soon-to-be victim who goes to sleep when her alarm clock reads 'Tue 11:06', and then we see the time morph to 'Tue 1:13' when the victim is sound asleep, before the unsub comes out of the closet to kill her. However, the time on the clock should actually read 'Wed 1:13'.
All Hell Breaks Loose: Part 1 - S2-E21
Continuity mistake: Before the Roadhouse fire, Ash and Dean are talking on the phone. Ash looks at his watch, on his left hand, it says 8:10, and has a black dial/face. As Dean and Bobby go through the rubble, Dean identifies Ash by his watch. Still on his left hand, it is now upside down, evident by the crown of the watch (used to move the hands of the watch) which previously facing his hand, is now facing his elbow. Also, the dial/face of the watch is now silver instead of black. This is a different watch, and was inadvertently put on the burnt arm upside down.
Plot hole: In this episode, the Duboises make such a big deal about Ariel being old enough to finally learn to drive. However, two episodes previously ("Things to Do in Phoenix When You're Dead") Ariel drove to school with Joe, and Joe complimented her on her prowess.
Continuity mistake: When Charlie Epps is writing a quadrillion on the whiteboard, the writing alternates between shots. Most noticably when he first writes it down, there is a significant downward tendency of the 000 groups. In the next shot, they are pretty much horizontal. Also the shapes of the commas alter.
Continuity mistake: When they first bring the girl to the house with the storm and lay her on the bead the there candles next to her. First the tallest one blows out then the middle one blow out then the shot changes and the middle candle blows out again.
Factual error: When Rose is introduced to the entire team McGloin shakes her hand and says that he (respects or admires) anyone that has survived the POW school. She smiles, nods and walks away. McGloin then explains to the last remaining teammate that all NIOs attend the POW school and explains briefly what it is. First: It is the SERE school. Survival, Evasion, Resistance and Escape not really POW. Second: Not all, not even most, NIOs attend SERE school, just some.
Factual error: Jonah tells Richard that Saturn has a "rogue moon" in a retrograde orbit that travels "at four times the speed" of Saturn's other moons. The graphic on Jonah's computer shows that the moon in question is Phoebe, which does indeed orbit in the opposite direction from other Saturnian moons. And the graphic correctly shows Phoebe's orbit as being much further from the planet than the other moons. However, as a direct consequence of its greater orbital radius, Phoebe is actually among Saturn's *slowest* moons. It has a longer orbital period (or "month") and a slower orbital velocity than all the Saturnian moons with smaller orbital radii, of which there are twenty.
Factual error: Molly and Ramsey find out that the van they are looking for was ticketed in Baltimore City at "the corner of Pennington and Fifth," and they are looking at a computerized map of the area. However, the map can be easily matched up to the actual Mapquest map of the area around the corner of Fifth St. and Patapsco Ave., except that the latter has been relabeled as Pennington. There is a Pennington Ave. in Baltimore City, but it runs parallel to Fifth, about a mile east of it.
Factual error: Haloclines are referred to throughout, and depicted occasionally as some sort of underwater tornadoes. Haloclines are in fact just salinity gradients, and look nothing like they do on the show.
Continuity mistake: When Miles jumps off the ferry to swim ashore, the camera view is from the ferry: he jumps into quiet, fairly level water, yet the camera recedes from him (he jumped off the back of the boat as the camera continues moving with the boat). The angle changes and we see the wake of the boat - but it's not what he jumped into.
Continuity mistake: As Dave is leaning over the edge of the air boat with Rose behind him, he pulls a chunk of metal out of the water and places it on the edge of the boat on his left side. When he gets up from his lying position moments later, the metal is gone. Moments later again, with an overhead shot of the boat, we see what appears to be that piece of metal positioned at what would have been his right side, not his left. This is also where we see him step over the seat (twice!) in subsequent camera angles. (00:30:00)
