The Crab with the Golden Claws: Part 1 - S1-E1
Continuity mistake: When Tintin is back at his apartment reading over the wrapper, the only things on his desk are the wrapper and pencil in the shot where he says "Only I can't read it" and the desk is also in front of the chair Tintin is sitting at. Later on, after Tintin returns to his apartment after the three bad guys have kidnapped Mr. Kuraki, a phone has suddenly appeared on Tintin's desk and the desk is now on the left of the chair.
