I just hope that Jason finally steps up his game in this book and gives us a reason as to why he's all soldeiry. If he experienced some traumatic thing in the past because he didn't follow orders or anything, I would probably immediately stop hating him. Jury's out on whether I would start liking him though.

Unless RR comes to his senses, Jeyna will never happen. The only way I can see it happening is if RR either leads up to a HUGE fight between Piper and Jason, and then Jason realizes that Reyna is the right one for him, loosely similar to Percy/Annabeth/Rachel in the original series (emphasis on loosely), or if RR has an epilogue where Jeyna has happened and Piper is happy with someone else.

But neither will happen because RR wishes appease that small fraction of people who like Jasper.
