Audio problem: At the start, the car stops at the gas station (weirdly far from the pumps, for a start). Grooms talks to Monk then walks to the back holding the nozzle, stretching the hose taut, despite no filler cap on that side of the car. We cut to Monk, and we hear a clunk of Grooms attaching the nozzle (to what?). Later Grooms is still holding the nozzle, and as Monk goes inside Grooms is just wandering around aimlessly holding it.
Continuity mistake: When Natalie puts out the fire with the extinguisher, the nozzle is still pushed down when she uses it, but when she puts it on the table, in the next shot the nozzle is fully extended. There are a number of times during the scene, when Monk is trying to figure out how to use it, where the nozzle's position keeps changing between shots.
Continuity mistake: In the scene where the two guys are playing chess, the guy with the black hat knocks over the chess pieces after losing. He then starts scrambling up the pieces and leaving his hands near the chess board. When the shot changes to a wide shot of Monk walking away the guy suddenly has his hands on his head.
Continuity mistake: Whilst Monk is being introduced to the long standing winner on the show a stagehand is adjusting the microphone on his jacket with both hands. As he says "Are you almost done?" the shot changes and the stagehand is just using his left arm to adjust it. The stagehand then pulls his arm away but the next shot he is adjusting the mic again and using both hands to do it. It keeps changing throughout the rest of the scene.
Continuity mistake: In the scene where Monk meets Salvatore Lucarelli (Philip Baker Hall), Lucarelli is cutting up fisheads on a cutting board. Throughout the scene the fish on the table constantly change between shots. One of the notable changes is when Lucarelli is discussing the case he has for monk there is a shot of a fish, and when the shot changes you can now see the fish's head has all of a sudden been chopped off.
Factual error: Monk inspects the wrecked VW Beetle and notes that "the air conditioning is off." But it's a standard 1973 VW: they didn't come with A/C, and though you could add it, it tended to overstress the little air-cooled engine. Look closely and you can see that this VW does not have the bulky under-dash compressor needed to run an add-on A/C.
Factual error: Randy calls the cabin and gets a "not in service" message. But he should have heard an unanswered ring instead. The FBI agent tore the cord from the wall, which in the US does not generate a "not in service" recording. That only occurs when the phone company cuts off your service due to non-payment or cancellation. (00:30:00)
Continuity mistake: In the beginning of the episode when Ray Galardi is meeting with Steve Marriot the amount of sun between shots constantly changes between shots. One moment that is very noticeable is a shot of just Ray with the hill in the background and a lot of shade. After showing Steve it goes back to Ray and the sun is now very bright.
Plot hole: While convenient to the plot, the computer system used by the medical examiner is far too poor to be taken seriously for a high level agency. While Monk is unaware of deleting the files on the computer, why would there be a one button push to delete all the files on working cases? Even to not have some sort of password to delete files is questionable, as most systems in offices and workplaces will only have functions like this for administrators, executives etc. We find out that all the files are backed up and are slowly being recovered. However, these types of systems are primarily for emergency scenarios such as fire, flooding and so forth. With the ease that Monk is able to delete the files by accident, it seems a bit hard to believe how easy it is to do.
Continuity mistake: After Stottlemeyer says "Well I'm gonna make the most of it" (when he is talking to Monk in the backyard of the cabin and Monk is cleaning) he looks a little to his left and opens a beer can while his mouth is shut. In the next shot he is looking in a different direction and is smiling a toothy grin.
Continuity mistake: Whilst Monk is talking with Natalie and Julie about halfway through the episode, Natalie asks Monk whether he helped Julie to find somewhere to go to the bathroom. When Julie says she has managed to hold on Monk says, "isn't she a trooper?" and is pointing his finger at her and then lowers his hand. In the next shot showing Natalie and Julie, he is still pointing at them. (00:21:55)
Plot hole: Monk wants to take a look at the case that got Christie to leave the force. But given that they are ordinary cops they would not be able to just go and pull internal affairs files.
Revealing mistake: In the scene where Darwin and Monk are in the kitchen and Monk calls Dr. Kroger. Darwin pulls the phone out of the wall, but there is no line from the phone to the jack in the wall.
