Bring some peasants to gawk

You go outside, into the crowd, and find a few people who look like they'd be interested in seeing Evellyn in her bathtub. A burly lad who might be a blacksmith, a couple of swarthy sailors, a cheerful milkmaid, a tavern wench, a pickpocket in leather, a fat merchant and several others chosen more or less at random. One by one, you carry these people into Evellyn's bathroom and arrange them around the tub, looking down at her. Then you start up time.

"Eeek! Get out, get out, get out!"

A chorus of confused murmers goes off amongst the townsfolk.

"Wh- how did I get here?"

"Where are we?"

"Hey, is that Lady Evellyn?"

"Wasn't she just running around the streets naked or something?"

"She's pretty!"

"Eek!"

She sinks into the tub, below the thin layer of bubbles which is all that remains to preserve her modesty from the sight of these filthy peasants, and scowls at you. "You bastard! Get these people out of here at once! Have some respect for a lady's privacy!"

You smile at her, pick up her clothes and towel and casually throw them out the window. "Not for you they won't. You don't get any privacy without my permission."

"Thrice-cursed son of a dog! Who are these people? Make them go away!"

"Hey, I think those bubbles are popping."

"No!"

The small crowd gathers to watch as Evellyn cowers behind her rapidly depleting shield of bubbles. Soon enough she's going to have to make a break for it, and then she'll discover that you locked the only door from the outside. The only way out is through the window. You hop up onto the windowsill and make your exit, carefully avoiding the giant puddle of mud that lies just beneath it. Wouldn't it be embarrassing if you tripped and fell into that? Especially if you didn't have any clothes on.
