Throw Vanessa out the door.

She struggles as you drag her towards the front door, but she's too tied up to resist. The tavern patrons raise a glass to her, bidding her goodbye as you land one final smack on her ass and sling her out the door into the crowded main street, bustling with traders and peasants and all kinds of people. Her eyes go wide as the door slams shut behind her. She's looking out over half the people in the city, and they're all looking at her.

As people begin to notice her, and to point, she bites down on the gag in frustration. You can tell what she's thinking. The anti-wizard powder won't wear off for a while, and she can't cast any spells when she's tied up. She's going to have to hop all the way home, tied up and naked and covered with glitter, her burning red bottom exposed to everyone in the street. And, knowing this town the way you do, you figure nobody's going to help her out.

It's no more than she deserves, the little pervert. You watch her hop off and wonder where you're going to go next. You should probably return to Evellyn and discuss.
