Willow was about to ask if Selene was a mind reader when she revealed where her knowledge came from.
"Really?" she asked intrigued, "That's unique to you right? I mean Angel and the others they can't do that" Or at least they'd never mentioned it if they had.
The implications however hadn't missed Willow and she tried to shut down the part of her mind which was checking out Selene, and had been since she'd arrived. She really hoped that wasn't one of the things the woman could sense, though knowing Willow's luck it very much would be.
