Revealing mistake: 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. (00:37:15)
Near Death - S2-E23
Continuity mistake: 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. (00:25:10)
Near Death - S2-E23
Continuity mistake: 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. (00:08:15)
Can't Run, Can't Hide - S2-E10
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. (00:20:35 - 00:27:40)
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. (00:43:10)
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. (00:14:40)
Near Death - S2-E23
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.
Close Call - S2-E25
Continuity mistake: Though the camera angle doesn't change, the brightly lit Chinese-character sign on the wall outside the window moves several feet to the right between takes. (00:09:10)
Crazy Love - S2-E26
Continuity mistake: The flashbacks here contradict series canon. Nick's victim, Amaya, is shown to have been bitten (by him) several times. In every other instance, unless he had multiple captive ladies to "sip" from, Nick's bite was fatal in one go. In fact, it was a major recurring plot point that Nick "couldn't stop."
Partners of the Month - S2-E18
Continuity mistake: Schanke's mother-in-law had previously been established as dead, yet Schanke's talking to her on the phone in this episode. (00:16:25)
Father's Day - S2-E7
Continuity mistake: 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. (00:23:20)
Answer: Nick was sick and tired of being an immortal bloodsucker. He wanted to be human, fall in love, get married, have children, grow old and die. As for Janette, according to her, she fell in love and the passion she felt "cured" her of her blood lust.
