The Crab with the Golden Claws: Part 1 - S1-E1
Other mistake: When Tintin discovers the torn out part of the wrapper, Tintin asks "What are these?" and one of the detectives reply "Objects found on a drowning victim." At this moment, the Thompsons are shown holding six files in their hands, but the way they are shown holding it would never be possible. This is mainly due to the fact that the second file is located on top of another file to the left, but there are four others on top. These four files are creating too much weight and would have fallen over. (00:03:35)
Chosen answer: If Hector was seriously intent on removing King Ottokar's scepter from the glass cage holding it and launching it through the window with the camera, then Hector would have been forced to knock out the two guards so they would not have interfered with Hector's plan as soon as he removed the scepter from the glass. As for Hector, himself, was explained when Tintin was explaining how Hector stole the scepter. Tintin placed a twig inside the camera and it launched out of the camera. Hector would have placed the scepter inside of the camera, and would have been knocked unconscious due to the spring effect created when the scepter had been launched.
