ugh

You all wake up in an expensively furnished room. Where the authentic persian rugs don't cover the floor some marble tile peaks out all white and shiny. There is a piano in each corner of the room, several couches that look rather antique and even a chandelier. The whole thing would probably be very nice if not for the windows being covered in jugend-style iron bars, they're also not openable.
Around each and every one of your necks there is a black choker-like ring with a small blinking light on it. By a simple push of a button your captor can send electric shocks through them.
Diamond, by the way, is seated on a balcony some feet above you all.
