Espa Roba: The ESP Duelist - Part 2 - S2-E10
Continuity mistake: After Yugi says "I know Joey can beat him", it cuts back to the duel between Joey and Espa. In the shot of Joey, Rex can be seen behind him, but his bag (which was visible on the ground next to him throughout the previous episode) cannot be seen. Later in the episode, after Tristan asks Tea to give Joey a message, it cuts to a wide shot of the duel, and Rex's bag has suddenly reappeared on the ground next to him. (00:02:50 - 00:07:20)
