Factual error: The cop who arrests Nick reads him his Miranda rights ("You have the right to remain silent," etc.) But "Forever Knight" is set in Toronto. At last report, Toronto rather resolutely insists upon remaining in the sovereign nation of Canada, where the Miranda Act, a U.S. Federal law, is not observed.

Revealing: The re-use of a brief scene from the pilot episode, inserted during Nick and LaCroix's vampire battle in the warehouse, creates the unfortunate problem of Nick completely changing clothes in the middle of the fight.

Factual error: Nick tells fellow vampire Aristotle, "You still owe me for that time at the Battle of Hastings." Nick was brought across in 1228, or so the intro told us every week. The Battle of Hastings, as any British school kid knows, was fought in 1066, over 100 years before Nick's mortal birth.

Revealing: It wasn't supposed to be in shot, but the camera accidentally caught the stuffed caterpillar toy perched on Nat's desk in the coroner's lab. It was there because nursing mom Catherine Disher had her new baby nearby on set. Fans wondered, though, why the single, childless Nat would keep baby toys in the morgue.

Continuity: During his fight with Constantine's henchmen, the bullet holes in the back of Nick's vest disappear and reappear several times between shots.

Continuity: The godfather's thugs storm Nick's loft and riddle him with bullets. We actually see the bullets coming out of his back, leaving holes in the back of the vest he wears. But when the "vamped out" Nick turns around to face the camera, there are no bullet holes in the front of his vest.

Factual error: Nat's god-daughter Cynthia Luce is buried within a few days of her murder with an elaborate headstone already in place. (In reality, headstones take months to produce.) But the wrong name is carved on the stone. It reads "In memory of Cynthia Lambert."

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.
