Factual error: At the very end, Bridget Hellman is buried with a fully-engraved headstone in one just one day's time (which happens only in tv & movies: the process takes months in real life... er, death). She also spontaneously returns as a vampire without being "brought across," a violation of series canon, and she comes back mysteriously sporting 3 times more hair than she had as a mortal.

Plot hole: In the underground bunker, Nick demands to know why the vampires in Vietnam are feeding on the children "when there are so many dead up there". Yet later in this same episode (as well as at other times in the series), it's stated that "Forever Knight's" vampires can't drink from the dead.

Continuity: It's 9:10 a.m. outside the police precinct station, and after a 4-minute interview scene with no time lapses, it's 2:55 p.m. inside.

Plot hole: At the end, Nick and Schanke discuss the bruise Nick's blow supposedly left on Damir's jaw. But Nick didn't hit Damir. He grabbed and tossed him bodily into a trash heap in the alley - without ever once touching his jaw.

Continuity: Although they never reverse their direction, when Nick and Schanke are walking down the Toronto city street, they pass the same bright yellow discount store sign twice.

Continuity: In the flashback to 1228, Nick's just-awakened sister Fleur has her hair down over her ears, and is wearing a white night dress that covers her to the neck. Cut to a close-up and her hair is pulled back to reveal pierced earrings (unlikely in 1228, and did she sleep with them on?), and she's suddenly in a bare-shouldered gown instead of her night dress.

Continuity: When Nick and Schanke begin interrogating Sean, the tape recorder on the desk isn't running. It's going a few shots later, though, even though no one's touched it to turn it on.

Continuity: When Sean sneaks back into the night club owner's office, we can see as he enters that there is no one in the left-hand side of the room. Yet, as Sean sits down at the desk, Walken somehow emerges from the left corner, which we have just seen was empty a moment before.

Continuity: While he's talking to Janette at the Raven, the level of fluid in Schanke's cocktail changes all by itself from several inches down to nearly full again, even though he's been sipping at it throughout their conversation.

Continuity: Schanke's mother-in-law had previously been established as dead, yet Schanke's talking to her on the phone in this episode.

Revealing: When Schanke, in a huff, packs up his treasures and moves out of Nick's loft, he kicks the box of his belongings into the freight elevator, then gets in and closes the door. If you watch closely, you can see the cord of his duck lamp caught under the door, where it stays even after the elevator supposedly begins its descent.

Continuity: Nick and Schanke are interrogating a murder suspect and disagreeing about whether or not she did the deed. They leave the interview room together, and Nick's hair completely changes styles as he walks out of the room. On the inside of the door, it's combed down over his forehead and rather "fluffy." The minute he exits on the other side of the door, it's brushed back and slicked down.

Factual error: In the first scene, Dr. Dana says the asteroid heading for Earth is 5 miles wide, "larger than the one that caused the dinosaur extinction." The asteroid that did in the dinos is estimated by most scientists to have been 6-8 miles wide.

Continuity: In the flashback, the level of whiskey in the bottle changes from 1/3 empty to nearly full and back again as the shots alternate.

Revealing: After Nick demands to be told what's going on, LaCroix leaves - but his reflection remains in the mirror for a few seconds after we hear the sound effect of his flying away.

Continuity: The flashbacks here recount Nick's "bringing across." But for the second time in the series, the recap of this event contradicts the original pilot film version in that the characters have all changed costumes.

Continuity: While Nick is interviewing Dr. Linsman, the position of his hands shifts (from lying flat on the desk to held up near his face) every time the camera angle changes.

Plot hole: Dr. Linsman puts a heart monitor on Nick for the experiment, but for some bizarre reason, never questions why her "patient" has a resting heart rate of only one beat every ten minutes.

Revealing: At the episode's end, the sharp, moving background of nighttime Toronto from the top of the CN Tower suddenly shifts to a still, blurry (and glaringly obvious) matte image. The scene was partly shot atop the actual tower, but because high winds and sway made the location too dangerous, it was abandoned, and the bulk of the scene had to be shot in studio and processed.

Continuity: In the establishing shot of the epilogue, it's 9:10 on the clock outside the station. But in the very next shot, it's 7:10 on the clock inside.
