Yugi had Djinn's question in his head since Kaiba left the store. Even he didnt understand it. But wondered if maybe that Kaiba collected rare cards. The cards in the case he had brought were all rare and unique. "Maybe he collects rare cards. Ive been having the question in my mind and that answer seems to fit. I doubt i could ask Kaiba about it. He doesnt seem to be someone who would willing tell anyone his intentions or plans." Yugi theorized. He only hoped Kaiba would leave his Grandpa be about the card. "Though Grandpas card hadnt been thr only card he was looking at. He looked at you too. Thats ehy Grandpa called him out on it too."
