Breaking of the Sacred Seal - S3-E23
Continuity mistake: After Adrian realises Marcel was holding four of the five Exodia cards in his hand, Adrian comments "If you had drawn one more card, you would have completed Exodia" while holding onto Marcel's arm. In this shot, there is a small gap in between his little finger and his right finger. When the shot cuts to Marcel, the gap in between his fingers is closed. (00:16:52)
