"...All this time I thought it was Sora with the scrambled memories. I guess he wasn't the only one." He turned to face her again. "You're right about what you said. When I can't see you, you seem different." Riku paused, still facing her. The darkness of shadows on her told Riku she had short hair, and that she was petit. He could sense the general shape of her face, and that it was different than Sora's. The features, however... Those were harder to tell. "You sound like Kairi. But you look a lot like her, too, don't you."
