Hey all, this is my first post but I've been prowling the boards for ages. However, I'm not sure I've seen this discussed at all!
Anyway, from the Taravangian interlude it is pretty clear that absolutely no one has any foresight into what Taravangian's IQ will be on any given day in the future. Hence, why he has a test every morning.
Generally, I imagine this isn't too much of a problem - most people think he's simple anyway - but if he has any serious meetings with serious thinking then his attendants will probably re-schedule it on a bad day.
"However", I thought, "what about the meeting with Szeth?"
This meeting wasn't planned. Sure, Szeth was in Kharbranth for a little while before the killing and sure, Taravangian could keep his eyes on him. But he would have no idea which day Szeth would choose to strike, and therefore no idea whether he would be capable of having the conversation he had.
More importantly, he is described as having "keen eyes and a wise, knowing face". What are the chances that Szeth attacked him on one of his good days?
Is this a coincedence? Maybe it's nothing, but it just seems so darn unlikely!
