At time 1:30, it became clear that Kaiba gave Joey a black eye for hitting him right before the opening credits began.
When Yugi is looking at his cards, Cyber Jar can be seen as a spell card, not a monster.
Allusions to previous episodes include Tristan's quotes "My voice gives me super strength" (from "Everybody Hates Mako") and "In another few hours, the sun will rise" (from "My Cards Will Go On").
This episode contains footage from the Japanese version of the anime that was cut from the English dub. These include Tristan's fight with Duke (which was mostly cut), and Croquet stating that those who were working on creating the Egyptian God Cards had "died" (in the English version he said they "met with disaster"). Also, the scene where the man is thrown from the window was cut entirely.
