The Final Face Off: Part 5 - S3-E45
Continuity mistake: When Mai pulls Joey onto the bed after she pretends to be asleep, Tea can be seen behind Serenity, and Tristan can be seen behind Serenity, to her left. When the shot cuts, Tea is behind Serenity, more to her right, and Tristan is now directly behind Serenity. Tristan also goes from being on Yugi's left to being on his right, in between the two shots. (00:17:35)
