“This isn't the future my Necklace predicted! Everything has changed!”
Kaiba receives a vision from the Millennium Rod and changes his plan, choosing Blue-Eyes rather than simply carrying out the approach Ishizu expects. Her surprise is the essential response. She does not claim she meant something else or quietly revise the prediction to preserve her authority. For a moment, the person who has treated the coming result as settled encounters an event she cannot fit into that certainty. The scene's argument is narrower than a declaration that supernatural knowledge is worthless. Another supernatural intervention helps produce the change. What fails is Ishizu's confidence that her particular access exhausts the possibilities. Letting her recognize the failure keeps the exchange from becoming only Kaiba's boast. Knowledge can be real and still leave its holder unprepared for what happens next.
