The Seven Crystal Balls: Part 2 - S3-E4
Character mistake: Tintin mentions that they passed a beige car on their way to the road block with four people inside. First, they did not pass this car. The car stopped at the road block, and after they were asked about the black sedan, they drove away. Tintin, Haddock and the detective then arrived at the road block in their car, coming in from a different lane. Second, the car that was stopped at the road block only had three people inside, not four. (00:32:20)
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.
