I'm one of those weirdos that like the idea of Jasnah and Kaladin together! I actually think this book makes that more likely rather than less, for me... the two scenes the make me think that are the one with Jasnah asking Shallan about her impressions of him after meeting Kaladin just once (she seemed intrigued or troubled about something, as in unusually unconfident); and the other is the council of war scene after that, which is one of the only open displays of joy she shows in the book... when she's out punning Kaladin and seems to be enjoying the contest and or the shape his mind takes.
But that's just me : )
