It has occurred to me that I really have no idea why Dilaf had to catfish Hrathen like that. Was this on Wyrn’s order, or was Dilaf just... havin’ fun? Does he have fun anymore? If I’m understanding the situation correctly, Hrathen was just there to serve as a distraction, and the invasion was always going to happen, so I don’t know why Dilaf was going on about his victory or whatever, like messing with Hrathen had any bearing on the outcome.

I don’t know, there are a lot of things in this book that don’t make any sense to me when I think about them, I really just wanted to frame that whole bizarre situation as Hrathen getting catfished by this exotic 20-something little twink, only to find out that he’s actually his old septuagenarian headmaster from Bone School.

Which naturally leads into the question of how dedicated Dilaf was to keeping his cover, because you can’t tell me that the hroden/odiv (H/o?) relationship dynamic doesn’t go there.   

Elantrians

Questioner: You've made it clear that on Sel, all magic requires both location and shape to be dependent. But we also know Elantrians are consistently being renewed by [the Dor]. Is that because Elantrians' bodies have been changed a certain way or is that due to a large Aon Rao?

Brandon Sanderson: It is a little bit of-- It is more about the way they have been changed than about the Aon.

Questioner: Is that a spiritweb based or is that body change kinda similar to the Dhakor monks?

Brandon Sanderson: It is a mix of both. (source)
