I personally think the fight will result in Kaladin SOMEHOW gaining control of Szeth's oathstone(most likely with the help of Syl) and then commanding him to stop his attack. Then I think Dalinar and his people will interrogate Szeth thus finding out about the crazy kings plan. Since both Dalinar and Kaladin have showed immense honor throughout SA1 I think they will use their temporary power over him to release him from his oath as truthless, then give him the option to fight alongside them, which I think he will reluctantly accept. Upon having Szeth on their side it becomes only a matter of time before its revealed that both Szeth and Kaladin have special powers(which most likely is revealed in the fight itself) and then results in Szeth training Kaladin on how to better control his new found powers. Atleast I hope this happens because i feel really bad for Szeth since he seems like a genuinely good person caught in horrible circumstances, and i highly doubt Sanderson would consider killing off any main characters just 2/10 of the way in. The only thing for certain is that a meeting between them is inevitable..i just hope neither Dalinar, Adolin, Kaladin, or Szeth die as a result.
