Episode #3.5 - S3-E5
Character mistake: Fidel says that the victim "removed" the hard drive of his laptop, even pointing out an empty slot where the HD would be. During his massive overacting when he figures out of the solution of the case, Humphrey says that Jacob "wiped" the hard drive. (00:21:40 - 00:41:00)
Episode #3.5 - S3-E5
Continuity mistake: After checking the phone records, the detectives go talk to Drew. Throughout the scene he has his left arm perched on the back of the seat, or just down his side casually. (00:23:00)
Episode #3.5 - S3-E5
Continuity mistake: Showing it to the police for the first time, Marlon is holding the plane ticket in his left hand when the camera is behind him, the right hand in the frontal view. (00:29:05)
Episode #3.5 - S3-E5
Continuity mistake: The reconciled Camille and Catherine walk arm in arm towards the table with Dwayne and the others. The beers in the bucket in front of Humphrey change position/angle depending on the view. (00:50:40)
Episode #3.5 - S3-E5
Continuity mistake: When driving to the crime scene, the vehicles seen in the wing mirror are constantly appearing and disappearing instantly.
Episode #3.5 - S3-E5
Continuity mistake: The land rover is going on a track but the next shot inside shows a road in the side mirror's reflection.
Episode #3.6 - S3-E6
Continuity mistake: Chief Goodman has implicitly outed himself as a birdwatcher, and the others look at him with pity. When Fidel resumes speaking saying "Well...", Humphrey lowers his binoculars and moves the evidence bag from one hand to the other and vice-versa. Besides small jumps in continuity that occur, the evidence bag does a 180° between shots. (00:05:30)
Episode #3.6 - S3-E6
Continuity mistake: At the setup of the whiteboard, the name of the victim is shown in close-up. The letter R in 'Mark Talbot' is written with a full eyelet and the K has its oblique strokes that don't join together. In the next shot Dwayne is standing by the board and the writing changed. The mistake happens for the remaining names too, different between close-up and view of the whole board. (00:15:35)
Episode #3.6 - S3-E6
Continuity mistake: During the first whiteboard scene, you can tell different takes have been edited together because in some of the shots with the same angle (Danny John-Jules from the waist up) something happened that smudged away a bit of the vertical stroke of the first T in Matt Webster's name, and in others it is untouched. (00:15:40)
Episode #3.6 - S3-E6
Continuity mistake: Humphrey cracked the case; looking at the whiteboard, he says that the "Who" is kinda obvious. The names on the board are written differently than the first time. (00:16:00 - 00:38:00)
Episode #3.6 - S3-E6
Continuity mistake: In another bit of his ridiculously exaggerated lack of coordination, Humph knocks the whiteboard down. He is reaching out with his left arm to tap it, actually taps it with the right, Dwayne catches the board, and in the next shot he's catching it again while Goodman pulls the left arm back. (00:17:20)
Episode #3.6 - S3-E6
Continuity mistake: At Humphrey's after speaking with Alec Burton, Camille is looking through documents when the scene begins. She lowers the paper in her right hand in the very first shot, it is higher up in the following, and she has yet to open the document folder in the frontal. (00:21:25)
Episode #3.6 - S3-E6
Continuity mistake: When Camille tells Humphrey about having a date with a swimwear model, she has her index finger less than one inch away from the label of the folder in the front views, but in the reverse the hand is noticeably lower on the page. (00:21:55)
Episode #3.6 - S3-E6
Continuity mistake: Goodman asks Yasmin Blake about the tour, and he traces the path on the map on the wall. In close-up, it's a right hand that does all the gesturing, but in the wider angles Kris Marshall has his right hand in his pocket, and it's the left he uses for that purpose. (00:23:15)
Episode #3.6 - S3-E6
Continuity mistake: Camille picks up a small copy of the map from Yasmin Blake's booth. She turns it 90° and drums its side with her fingers, but when the editing returns to the previous camera angle as it's time to leave, she's holding the map the same way as before, and with her hand firm on the side. (00:23:30)
Episode #3.6 - S3-E6
Character mistake: After a long day of various inquiries around the island and a lot of roaming and chit-chatting, DS Camille Bordey and DI Humphrey Goodman go back to the station wondering "if the photographs from Matthew Webster's camera have finished downloading." (00:23:50)
Episode #3.6 - S3-E6
Continuity mistake: When Humphrey basically sums up the case after he calls Dwayne "Master of the Understatement", Kris Marshall depending on the camera angle does his weird gesticulations with the left or the right arm. (00:26:25)
Episode #3.6 - S3-E6
Continuity mistake: When Goodman sticks on Dwayne the task of surveilling Captain Jack Parrot messing up his hot dating plans, Dwayne lowers his hand, and in the next shot he has it back up again. (00:26:55)
Episode #3.6 - S3-E6
Deliberate mistake: When Fidel pops behind Humphrey with the walking cane, in nonsensical fashion his cane switches hands in the brief moment when the camera moves from behind him to the front of Humph. It has to be deliberate since there is no cut, but Fidel is standing still both times, and Gary Carr must have done a sudden swap that has no reason. (00:28:20)
Episode #3.6 - S3-E6
Continuity mistake: At the beginning of the scene with the swimsuit model, the waiter comes out from behind the counter, moves behind Camille, but takes a couple seconds after he goes out of frame for him to appear behind Samuel Anderson. (00:28:30)
Answer: There's probably no particular reason. Sets and props on long-running TV shows often change as needed and for various reasons throughout a series run.
