1: Seto Kaiba Kaiba who? You mean Noa? The "other" one? ...Mokuba...? Which "'other'-other" one?? "Who hosted Battle City"? Idk, some rich guy. Atem's "card games rival"? No, that was Marik Ishtar, he's not even from Japan, he's not a Kaiba. Who are you talking about??
2: the "Undead Lock" deck/strategy No longer remembers what his planned strategy was for the duel he has with Yugi in the Millennium World arc - the duel itself is from right after his canon point, but now he can't remember what the plan was, though he's sure he had one.
3: Shadi's portrait Remember when he was mildly surprised to find a portrait of Shadi in Pegasus' castle during the Duelist Kingdom arc? The Ring-Spirit doesn't.
4: the "Atem Despairs" mini-arc A plotline in Ryslig where Atem briefly gave up on life and existence as a whole, no longer seeing any point as he couldn't control either. (Atem and Ryou had also lost their memories of this event.)
5: how he defeated Pegasus No one knows how exactly manga-RS managed to defeat Pegasus in a card game to collect the Millennium Eye. Sure in the anime he used Ancient Egyptian Laser Beams, but this guy is manga canon. Well now RS has no idea how he did it either, plot hole solved.
