Wait how was it an accident? I thought he had them arrested on trumped up charges and then repeatedly delayed their trial when he realized that the trial would make him look bad. Not a very bloody murder, but it sure felt intentional. He had to know people their age wouldn't last long in a cell.
Thanks for the WoB reference. I've read every book, but I've done very little reading of what I guess you'd call 'unpublished' sources (not sure if there's a better word for that). I'm just dipping into those now.
Thanks! I'll do that. And wow. I don't know how I missed so many hints. I've been considering doing a re-read now that I'm a bit more 'Cosmere aware'. WoK was one of the first Sanderson books that I read, so I probably missed tons.
