It really depends (Possible spoilers). Milisandre thinks Jon is the re-birth of Azor Ahai, who will fight the Others, this could mean that the typical fairy tale could take a darker turn as the only way the chosen one could unlock the power of his sword was by driving it into the heart of his wife.

I'm pretty up-to-date on the books so I have my own theories about how this is all going to play out in the end. It'll be interesting to see how the show goes on when it doesn't have the books to use as a reference for conversations and plot points.
