Whatever the Case May Be - S1-E12
Continuity mistake: After Kate and Jack dig up the marshal's body, Kate opens his wallet. In this close-up, as the pocket for bills is at the top, the vertical slit with his ID is on the right and the horizontal slits with laminated cards are on the left. However, in the close-up when Jack holds it, as the pocket for bills is again at the top, this time the vertical slit with his ID is on the left and the horizontal slits are on the right. Surprisingly, neither are flipped shots. Two different wallets were used in each close-up, though similar in style, the storage slits are on opposite sides. (00:28:05)
