There are scenes that don't appear in the gallery, right?i send here post about this scenes
but this one, i guess, you can trigger if you try to plunder drunkard in red district on bench in nighttime. Smile on face, if i remember it correctly, triggers if you have sadist background
and i make more research and found out that if you have big stat for this type for interaction - you can make leg lock to bunny girl too apparently (i didn't test it - only check it in game files) + you can win bodyguards when you trying plunder inn keeper second time.
