The Crab with the Golden Claws: Part 1 - S1-E1
Continuity mistake: When Allan and his two crew mates go to question Tintin, they enter a room with a teal door with a handle. When they are inside the room a few inches of hull are shown under the door. As the three go to leave the room after the questioning, the teal door is now grey with a knob, and almost a foot of extra hull is now shown beneath the door. (00:12:25 - 00:13:00)
