There are a few more shown in the page where they're arguing with Numair as he sets up the broadcast; but not many. Maybe it's a really small council, only about eight people? But I do wonder what happened to the rest -- does the building have more than one exit, and they headed in another direction? did they move more slowly, and are coming behind this group?
-- and, considering that slam: I wonder if they're storming back in to try to stop Numair, by any means necessary. The crowd will hear them, at least unless/until they get the broadcast stopped; and the scribes are witnesses. Though I suppose if they're willing to stop Numair by killing or imprisoning him, they wouldn't hesitate to do the same to the scribes.
I wonder whether the Council thinks they can order Sraddi to stop broadcasting? And if so, I wonder whether they're right?
-- but the crowd would in any case know that something had happened. And if the Council tried to explain that Numair had just had a stroke or something, I gather that there are too many truth seers among the spirits for that to be believed.
And in addition to all the other things I'm wondering: I'm wondering whether Hawk is listening to this. And if not, how he's managing to avoid it.
