Corrected entry: Walter White correctly starts to lose his hair at the beginning of the chemotherapy. The errors occur afterwards (I know this from my own experience): 1. The mustache would fall out as well, 2. Walt has hair stubble throughout the treatment (and even has to shave his head!), while in reality a "chemo-head" is simply bald as a baby face since the hair is gone.
Corrected entry: Walt steals 2 masks from the school lab. When they go cook and Crazy8 and Emilio show up, he kills them with the gas. Because of the fire he puts one of the masks on himself and the other one on Jesse and they drive away with both masks, but the DEA find one of the masks at the cook site.Hmhmh
Corrected entry: When Badger is demonstrating the "Helicopter" to Jesse, he spins the sign in such a way that he would be holding on to something in the middle of the arrow on his side. However, when he brings the arrow down, you can see that there is nothing he could have been holding on to.
Corrected entry: The ricin poison that was originally intended to kill Gus, and which was 'apparently' intended for use on Brock, doesn't make sense. Brock was fine in the morning, but fell ill at night, seems legit. However, Jesse exclaims to Walt that he had the cigarette containing the poison the same morning. Earlier in the series, Walt had explained that after indigestion, it would take 36 hours for any effects to have taken place, so, in this instance, Brock could not be hospitalized within 12 hours.Callum Lloyd Edwards
Corrected entry: When Walt is building the battery and explains how it works to Jesse, he says that the cathode is the positive terminal. The cathode is always the negative electrode and the anode is always the positive electrode. Walt is a chemistry teacher who would know the difference.
Corrected entry: When Walt calls his wife at the beginning (the flashback), he tells her Bogdan is keeping him late. His wife also says she likes the name Holly for the baby. But if you watch the beginning episodes, Walt quits the car wash right away. And also finds out he's having a baby girl fairly quickly (episode 2 or 3 I think) Nowhere in that time frame did Walt and Jessie go cook. They had only cooked once so far, and then had to deal with Crazy 8 and the other dude. So Walt was never working for Bogdan except for maybe when they first cooked, but even then he would not yet have known he was having a girl. There is no way the timeline can work with that phone call flashback.
Corrected entry: Jesse takes a hit from his pipe, at which point, you can see a vaporizer device in his hand. This is used in production to create the white vapor smoke that they exhale while smoking. It has a metal mouthpiece and what looks like a small LCD on it. It is not a glass meth pipe.
Corrected entry: During the scene in which Gus is talking on the phone with a "colleague" of his, the boss of the two assassins who shot Hank, it is night time and the surroundings outside of Los Pollos are dark. However, when gunshots are being heard in the background and Gus snaps his cell phone in half it is daytime. The sky is blue behind him and the sun is shining off of his head.
Corrected entry: In the desert, after Hank witnesses the head on the turtle, he runs off to his pick-up truck and catches his breath on the driver's side (left). The next shot is from behind the other cops grouped around the turtle. The vehicles can be seen in the background with Hank standing casually on the right hand side of the pick-up with the left door still open but no-one behind it. The shot then returns to Hank on the driver's side.
Corrected entry: In the opening teaser scene they show a man in a hazmat suit bagging evidence from the later revealed plane crash. One of the bags contain the eyeball from the pink bear. However in a future episode Hank discovers it in the pool filter, after the hazmat team would have bagged it.
