Very hyperspecific (and kind of campy) whump scenario I’m insane about:
A carnival, masquerade party, a congregation of a secret society where everyone is cloaked/masked…any sort of fancy-ish function that involves people having their faces and bodies obscured…
Whumpee, for some reason, is taken to the party together with their captors. Everyone assumes they’re an ordinary guest that’s just too shy to talk and move around much, because their cloak goes over their tied up hands and ankles(loose enough to slowly walk, tight enough to restrain from running) and the well-fitting mask, strapped to their face, obscuring the duct tape across their mouth
(bonus even more obscure detail: if you look closely enough at the side of their head, you can notice the tape showing under the head straps)
