Land of Black Gold: Part 2 - S2-E11
Continuity mistake: After Mueller has caught Abdullah, Tintin shoots the lock off one of the cells and hides in it. When he is inside, the bullet damage from when he shot the lock is visible and is coloured green. A few shots later, the damage is suddenly beige and the same colour as the door. Then a few shots after that, the damage is suddenly green again. (00:37:25)
