Surprise melted away into a sort of sadness because the idea of Ignis guarding his heart so deeply that even Gladio wouldn't be able to get in... it hurt. Was it because of what happened before he had been sucked into the crystal? Something after?

Noctis can't even imagine the possible real truth, that Ignis' heart belonged elsewhere.
