Shadenight hasn't really responded to my PM, so I'm going to take a liberty...
You maintain the awkward silence, periodically glancing over at Miss Shuu and making a small "Hmm" noise. The poor girl continues sitting still, practically sweating from the effort of maintaining a perfect upright back. About ten minutes pass in this manner; just as you think Shuu is about to crack and say something, the dinner bell rings. You motion towards the dining room and Miss Shuu practically leaps up in her hurry to get away from the situation.
Dinner is served by your full staff of liveried valets, their raiments in impeccable order and condition. The same could not be said for their skin. Oh, you've tanned it and soaked them in formaldehyde until the house stank of it (you silently thank Nives for taking care of that) but dessication happens anyway. The ultimate effect is that of being served by absurdly well dressed mummies. The glass eyes probably don't help either. You begin to wonder if this might be why people keep coming up with excuses not to come to your parties.
Dinner, at least, is much more appealing. It's the season for it, so Ras has cooked up grouse with a side of potatoes and creamed spinach, along with an excellent wine, and you believe there is spotted dick and custard to follow. You tuck in vigorously, and the food is excellent; Ras really knows what to do with herbs and spices, and it's roasted to perfection. In fact, it's only a minute in that you realise Shuu is staring blankly at her food, cutlery undisturbed by the side of the plate. There is a faintly terrified look in her eyes.
What now? Will you comfort her, interrogate her, or just let the awkward silence prevail and enjoy your dinner?
