The Final Face Off: Part 5 - S3-E45
Continuity mistake: When Kaiba is about to begin explaining that the island will self-destruct, in the shot of him saying "This victory celebration has gone on long enough", Ishizu and Odion cannot be seen on the platform with the other main characters, despite being seen standing behind Marik throughout the scene. Later in the scene, Ishizu and Odion can be seen standing on the platform next to Marik in the wide shot where Kaiba says the tower will self-destruct in one hour. (00:15:08 - 00:15:32)
