As soon as Xion's arm was released, she stepped back away from him, trying to get out of arm's reach. Hopefully, he'd take that punch as a warning and back off. Out of the corner of her idea she saw Namine melting away into the shadows again--hopefully she wouldn't go too far and risk running into someone even less pleasant than the mirrored Riku. This was one instance where fleeing wouldn't always lead to safety.

Riku's question left Xion confused for a moment. Then she remembered his ability to "smell" others. Apparently that hadn't faded even here. How to answer, though...Did this Riku just not remember her, or had he never met her. Whichever the case, a small, petty part of her refused to explain herself to him, and that was speaking the loudest at the moment. So she settled for just looking warily back at him, still in a stance from which she could easily defend or attack if she needed to again.
