Obviously, the thing that has most fans salivating at the mouth about the upcoming new season is what will the fate of Jon Snow be. And as seen in the above teaser art, showrunners David Benioff and D.B. Weiss have dropped all pretense and accepted that fans know Jon Snow will return. He might be dead, but as we explained here, he's just mostly dead in the George R.R. Martin saga.
Indeed, with Jon Snow's murder happening only within hours of Melisandre, the red priestess, entering Castle Black, it seems inevitable that the red god magic that resurrected Beric Dondarrion would be worked on Jon Snow. The Bastard of Winterfell, Lord Commander of the Night's Watch, and all around most handsomest bloke in the Seven Kingdoms is just too important to yet die. And we have had months of evidence that began with Harington finding himself photographed with Snow's trademark long locks (a look he apparently hates). He was then subsequently spotted at a Belfast airport (where Game of Thrones shoots) just as season 6 began production. You can view both images below.
