Please excuse if there is any lack of understanding, post after a reread of TWOK and may be loosely related to this thread.
Everyone was discussing/predicting about szeth & kaladin fight, but I haven't seen the posts about why had taravangian send szeth at the time he did to kill dalinar?
Taravangian had szeth, orders to kill some important figures (high princes, king) but not dalinar on his first assignment, but orders to kill him on his second assignment (just after the failed attempt from sadeas to abandon dalinar on tower, just after navani confirmed his visions to be true).
What has changed his mind?
What did he find about dalinar plans/visions?
Who is providing him the information? (if not for the POV from Navani, i would have suspected her because of here privy to the dalinar's visions)
