That could be the case, not sure why I'm thinking that he was sent, I will have to look for that. Not sure why Borden would have it in his mind to bring a madman to Dalinar, Borden was even at the gate. Small thing I guess but it does intrigue me.
@Patrick Star You're probably right, might be straightforward but it does seem to be a big thing that one Herald is a traitor. I also hope there is some twist or at least more intrigue, I think of WoT and how much plot was involved around guess who was who.
