This string of commentary left Oz arching one brow in her wake. Whether or not she had met him depended on how one defined the 'self.' If she had met him, but he hadn't met her, that didn't necessarily mean they had never met. Oz rode that train of thought for a little while longer until he came to the conclusion that it didn't matter so much whether or not they'd actually met, since to her they had. Oz found himself wondering what it would take for him to tell someone what he was. Maybe he had an actual serious relationship with this girl. It seemed a bizarre prospect so soon after Willow.
Frowning, he stood up and moved through the crowd. He touched her on the shoulder, catching her staring at the door. "Did something happen when I was here last?" That was Oz: intuitive, direct.
