Don't know if Jon Snow will be alive after the last episode of the season, since it's pretty much some kind of sacrifice (his life for Mance's one). Sadly, in two episodes, I saw 5 of my favorite characters diying. I think this autor is a psychopath after that, really... Oberyn didn't even make a season for fuck sake, Pyp and Grenn were two good characters that didn't deserve to die, even after 3 seasons. New characters will appear magically from nowhere, and die, be replaced etc ... Only thing I dislike in this serie, but whatever, since you never forget after an episode of Game of Thrones that life isn't heaven.
