There is something that a few of you have touch on that I think should be revisited in greater detail with regards to the Kaladin/Jasnah potential relationship (this may seem like a reach at first but bear with me).
Jasnah has tow sides in my mind. There is Jasnah the scholar who is a competent, determined, and brilliant researcher who is absolutely focused on unlocking the mysteries of the Voidbringers. To Jasnah the scholar, Kaladin probably ranges somewhere between a curiosity to a mild annoyance. A bright and quick witted man might intrigue her or their head strong personalities might initially get on each others' nerves.
However there is also a second side to her, a Jasnah the Machiavellian Politician, who is totally committed to defending her family, its power, and its prestige. This is someone who doesn't flinch when dealing with the Weeper, someone who says morals and virtues be damned and the ends justify the means. From the perspective of Jasnah the Machiavellian Politician, Kaladin is the most dangerous threat to her and her family, save the voidbringers themselves. Kaladin is currently the strongest combat radiant by far, he is the only leader of a radiant order not currently or soon to be a member of the Kholin Family, he is the captain of bridge four who may soon be an entire squad of windrunners, and he commands the undying loyalty of the bridge crews which are essentially a small army. He is a strong critic of the king, and he hates light eyes and everything they stand for. To have such a potent political adversary outside the control of the Kholin family would be simply unacceptable.
To make matters worse, think how Jasnah could meet Kaladin. The guard (or former guard) of the royal family encounters someone claiming to be the relative of said family, someone that Shallan confirmed was dead, who is asking to speak with Dalinar or the King or both. Given the information that Kaladin could have at the time, he would have to be an idiot not to arrest her, for she could easily be an assassin. What does it say to Jasnah about this man and his influence that he can just arrest the King's sister?
How would Jasnah react? Would she try to have Kaladin killed and hope that the Kholins will be able to weather the blow-back from the bridge crews? Would she try to incorporate Kaladin and his power base into the Kholin family? If so, how? She can't really arrange a marriage between Kaladin and Renarin like she did with Shallan and Adolin. Does she sacrifice herself for her family, and commit herself to a subversive relationship with Kaladin? Does she make some kind of deal or trap Kaladin using some sort of subterfuge? The only thing I can say for certain is that Jasnah is not the kind of character to sit on her laurels. She is the proactive type, and that will lead her into serious conflict with Kaladin in the not so distant future.
This theory may sound either too much like a Greek tragedy or too outlandish for some but I think BS has demonstrated that he can write exceptionally dark, disturbing, and unexpected narratives from time to time.
