Settling the Score: Part 1 - S3-E11
Plot hole: When Nezbitt starts attacking Kaiba, Kaiba throws a duelling card at Nezbitt. However, Kaiba shouldn't have a deck of cards on him at this point, as the rules of the virtual world only grant him a duelling deck when he duels someone, which he doesn't do until later in the episode. (00:02:14)
Plot hole: At the start of the episode, there are three of Kaiba's men trying to get the engines to the blimp started so that they can leave before the island explodes. After the main characters realise they won't be able to get the engines started, they decide to get on the helicopter and leave in that. However, only one of the men from the control room can be seen boarding the helicopter. The fates of the other two men are never addressed, even after the island explodes. (00:03:20 - 00:08:07)
