Kaladin and Beard have a quick and silly exchange regarding the story Beard told where he swam in the Purelake with Dalinar. Beard admits to lying about it being Dalinar, at Kaladin's insistence. Beard finishes by saying it was actually the Azish emperor. All I'm saying is, Beard knows that Gawx became the emperor, and may know more than he lets on.
I apologize if this has been mentioned before, but I could not find anything on a basic search.
Let me know what you think!
