Seeing and sensing were very different things. That being said, what he could tell from her face wasn't much. It had taken him a while for him to learn to make out expressions on most people. He couldn't sense color, and fine details were muddled, particularly on Xion. Riku would have assumed she had indigo eyes and red hair. And even then, since he'd used his own eyes to see her, he still got an occasional feeling of Sora being there. (http://i15.photobucket.com/albums/a360/Rebmakash/MiscArt/xionrikusvision.png)

"You should. To Sora, she's someone very special." Something felt very familiar about those words. Still, he smirked a bit. "I wouldn't have come today if it weren't for her. She's around."
