Breaking of the Sacred Seal - S3-E23
Continuity mistake: When they have finished setting up the inter-dimensional duelling system, there is an overview shot that passes over the main characters. In this shot, Pharaoh can be seen sitting on a console, directly in front of Blair. When the shot cuts to Blair and Pharaoh, Pharaoh is now sitting in front of Blair, to her right. (00:19:30)
