I just don't see them go through all the magical weird stuff associated with Azor Ahai and a resurrection.The show has been pushing the Jon's honour and commitment a lot this season.Refusing the Stark name and Melisandre advances,even putting an arrow through Mance.Would be a big leap for him to go from that to being involved in some sort of fiery ritual.You never kniw though.
That's right,it would be weird if they showed zero resentment from the nights watchs side.
Did Robb legitimize Jon in the show like he did in the book? I can't remember. I know in the books it's done but there isn't time to send it out before the wedding.
