Corrected entry: When Sherlock and John are in the cab going to see the lady in pink's crime scene, John is on the right side of the back seat, Sherlock on the left. During one shot, they are on the opposite sides. The next shot they are back to the original.
A Scandal in Belgravia - S2-E1
Corrected entry: It was impossible for Sherlock to guess the password to the safe in Irene's house. Even if he knew which numbers were pressed frequently he couldn't have guessed the order. (00:20:00 - 00:21:00)
Corrected entry: In the viewing-a-flat-scene, Sherlock has just moved in and Inspector Lestrade enters the location asking for his help in the case of the serial murders. But how does he already know that Holmes is at this address? (00:15:15 - 00:16:00)
Correction: Obviously, Sherlock gave Lestrade the new address in case Lestrade needed him. There was plenty of time for Sherlock to have done this off-camera, or even in the time before the show started. We also know (from Sherlock's texts to Lestrade and the reporters at the press conference) that Sherlock is eager to get involved in the 'serial suicide' case, so it is logical that he'd make sure Lestrade knows where to find him at all times, in case Lestrade does decide to finally call him in.
Corrected entry: At the end of the pool scene, Moriarty unexpectedly returns and threatens to kill both Sherlock and Holmes, who are covered in the red laser points of unseen snipers. Sherlock counters by pointing his gun at the explosive vest still lying on the pool deck between them, implicitly threatening to blow up Moriarty and himself. Neither shows signs of backing down, and the season ends on this cliffhanger. However, the explosive has previously been referred to as Semtex and also has the characteristic reddish color. SEMTEX is a mixture of RDX and PETN which is highly shock insensitive, meaning it does not explode when shot. Moriarty and almost certainly Sherlock would both know that. (01:28:35)
Correction: Holmes is aiming at the detonator, which is most certainly not shock insensitive. Once armed and primed, a Semtex bomb is susceptible to bullet impact - if the bullet is well placed. Holmes obviously knows that.
Corrected entry: In the scene where Holmes, Watson and Lestrade are looking at the woman's body, Holmes keeps saying that she has mud splashed up her right leg, but the splash is on her left.
Correction: Having double-checked the scene, the splash marks are on her right leg. You may have mistaken her shoes, seen on the right of the close-up image, for the bottom of her identically coloured coat - had it been the coat, you would have been correct.
The Hounds of Baskerville - S2-E2
Corrected entry: Dr Frankland refers to his "cell number. No British person refers to a mobile phone as a cellphone.
Correction: It's actually a plot point, revealing that Frankland had spent a long time in America.
Corrected entry: When Watson was in the well he was chained down, so the way they rescued him with a helicopter using only rope makes no sense. He couldn't have climbed the rope while his legs were still chained down.
Correction: It would be a small matter to lower him bolt cutters or some other device to detach the chain before lifting him out.
Corrected entry: In the pool scene, after Moriarty leaves, Sherlock sets the gun on the floor to help John out of his coat. After he gets it off and tosses it away, he goes off screen for a few seconds. He did not pick up the gun before he left, but he comes back holding it. (01:26:45)
Correction: When Sherlock goes off screen, he goes to pick up the gun and search the area for Moriarty and the snipers. It is obvious that Sherlock picks up the gun because he is seen bending down just before going off-screen.
Corrected entry: At the Connie Prince case, when Sherlock and Watson are in the restaurant watching the news on TV about the death of Connie Prince, on the screen appears that Connie was 48 years old. But in the next scene, at the morgue, Lestrade reads from the "patient" record that she was 54. (00:38:30)
Correction: Not at all unheard of for a celebrity, or indeed anybody else, to lie about their age. The media reports give the age she claims, her medical records show her true age.
Correction: If you look closely you'll see that in the shot where their positions appear to be reversed, we are actually seeing the view in the cabbie's mirror - so it's not a mistake.
