Continuity mistake: Mike is sitting in a diner as a waitress is walking up to him. The shot is from outside the window and shows the reflection of a mixed race couple walking across the street towards the window. When the shot changes to the waitress coming up and bringing him his drink, there is suddenly nobody in the street at all or around that could have been making that reflection. (00:31:20)
Factual error: Around the beginning of the episode, Saul is entering a Ford F-550 Bus from Sandpiper, but that body style from the Ford F series isn't introduced until 2012+ and Better Call Saul takes place in the early 2000's, 6 years before Saul meets Walter.
Factual error: When Jimmy is dropping his ice cream as he enters Nacho's car, a third-generation Land Rover Discovery can be seen turning in the background. The episode takes place in 2004, but the third-generation Discovery did not go into production until 2017. (00:44:12)
Continuity mistake: When Victor gives the sixth drug loaf under Nacho and Arturo's insistence, the loaf's position changes in two different shots.

Continuity mistake: Mike sets a trap to taint a cartel's truck with drug residue. First, he inserts a bag of cocaine in a shoe, then throws the pair of shoes over a telephone wire. His plan is to shoot the hanging shoe so the cocaine powder pours out onto the truck as it passes under the wire. However, when he inserts the drugs it is in the right shoe, but later, it is the left shoe he shoots and has the powder in it. (00:29:30 - 00:38:00)
Factual error: If Chuck had shut off all the electricity, the meter would be moving imperceptibly slowly, if at all. (00:30:31 - 00:34:20)
Continuity mistake: In the desert, when Bolsa is interrogating Nacho, Nacho looks towards Gus. A shot of Gus is shown with a blue sky behind him, with a few clouds. It cuts back to Nacho and then back to Gus, where the sky behind him is cloudy. The change in the sky happens a few more times throughout the scene, going from clear blue to cloudy, then back to clear blue.

Continuity mistake: At the end of the episode when Howard is at Jimmy and Kim's apartment to talk with them, there's a bottle of wine on the table next to the couch, but when there's an overhead shot just after Lalo comes on stage and kills him, the bottle has disappeared without anyone having touched it.
Continuity mistake: When Betsy Ketelman storms out of Cliff's office after being rejected for representation, she leaves her purse on the couch. In the very next shot with her walking out the door, her purse is back on her shoulder. (00:27:00)
Factual error: In the scene of Jimmy driving with his new Mercedes, we can see a Subaru forester that is definitely a model after 2010. Season 2 is set in 2002 so this couldn't be possible.
Continuity mistake: Hector goes behind the counter in Los Pollos Hermanos and helps himself to a drink. The cup is under a different dispenser (and therefore a different drink) each time the shot changes, but the audio of the dispensing and the cup being filled remains intact throughout.
Continuity mistake: In the scene after Jimmy/Saul and Mike in the desert with the seven mil, they are each sitting on one of the duffel bags of money at the gas station. Mike puts his big drink up to his head and his watch reads 6:35 but in the next shot it reads 3:00.

Other mistake: While setting up the shot to drop drugs on the Salamanca truck, Mike puts the drugs in the left sneaker. He later shoots through the right sneaker. (00:29:29 - 00:38:06)
Factual error: Tuco Salamanca's gun is a Taurus Raging Judge. Season 1 - as well as Season 2 - where Tuco's gun is prominently featured, are set in 2002. The Taurus Judge series wasn't produced until 2006.
Factual error: In one of the shots shown of Chicago, the Trump Tower can be seen on the right. Although the episode is set in 2002, this building did not exist until the late 2000s. (00:28:33)
Continuity mistake: Jimmy gets ambushed. One gang member holds a gun close to Jimmy's face, but in the next shot the guy is way further away from him and not even visible in the shot when Jimmy gets splattered with blood.
Visible crew/equipment: At the end of the episode you as Jimmy is sat on the floor, you can see the head of a camera man or sound technician duck down to the left of Jimmy.
Factual error: When Hector and his men are in Los Pollos Hermanos there's a soda machine in the background with the current logos of the sodas when this episode took place before 2003. (00:12:33)
