"OK Karyn, what did you do to me?" Jon asked, getting straight to the point.
"Now now, all in due time." Karyn replied, standing up and pulling a mirror into view. "Now tell me, what do you see?"
Looking at the mirror, Jon saw himself, but his clothing was... strange. All white, and some of it was patterned, but for some reason, he just couldn't name any of the items. He just looked at himself and racked his brain for answers, only to get nothing.
Karyn grinned as she saw Jon trying to work out that he was now in white lingerie. While he was out, she'd swapped his outfit for the lingerie (and included an additional surprise for Jon later), and used the hypnosis to bring his knowledge of clothing to such a low point that asking him for a sock would completely stump him.
While she could use the stone to mess with his body though, she decided against it. One way or another, Jon would still physically be a guy at the end of the day, but she wanted to see just how much of a girl she could make him through nothing but what he was wearing and how he thought.
