Before we begin. Obviously major spoilers ahead. OK? Right, I've warned you.
So, in the Game of Thrones Season 5 finale, Jon Snow was killed by his fellow members of The Night's Watch. Missed the heart wrenching scene? Watch below:
Right then. If you watch the Game of Thrones show- you may be thinking 'surely he isn't dead. There must be way he didn't die!' On the other hand, book readers and G.R.R fans are thinking something more like 'Right, so now Jon Snow IS dead, how's he going to be bought back?' Any book fan will tell you that somebody is only really dead if we see their body being put into the ground (maybe not even then). There are fan theories about pretty much everything in the Thronesiverse such as The Hound / Gravedigger and Ned Stark being alive or resurrected himself. Some even mention the Baratheons. And, of course, the books themselves often bring people back (aside from White Walkers) such as Lady Stoneheart. Jon Snow is a character of extreme importance and has often served as the book and show's protagonist, plus all of the R+L=J stuff. This makes us wonder... how exactly will Jon return?
Because, let's face it, he's not gone.
Outcome 1 - Melisandre resurrects him
This one is probably the most obvious. We've already seen that the red priestess recognizes Jon's importance in episode 4 [Sons of The Harpy], and we know that following the Lord of Light means you're prone to gravitating toward both sacrifices and resurrections. Also seen with Thoros of Myr resurrecting Beric and, unfortunately, Shireen. How interesting would it be to see fire and ice collide in such a way? She's already back at the wall, so we know she'll find out about it sooner or later, even if the Night's Watch attempt to cover their tracks. This method of resurrection is least likely to alter and change Jon in any way.
Outcome 2- He becomes a White Walker
OK, so this has been circulating for a while, especially now that White Walkers are really in the spotlight after that crazy eighth episode. Now say if the Night's King or any other Walker finds Jon's corpse abandoned in The Haunted Forrest or anywhere else around The Wall. We all know he wouldn't be ignored. They've seen how important Snow could be as an ally. Plus, Jon has this unshakable honour and sympathy for others considered enemies (which is what got him into trouble in the first place) and therefore could even become a new kind of White Walker, one with human capabilities.
Outcome 3- He wargs into Ghost
In the Game of Thrones books, all Starks are what's known as Wargs. If you're not sure what this means, it's basically what only Bran does in the show- his eyes roll back into his head and he sees through the eyes of his Direwolf. There are a few other branches to this ability, but the main feature is the posession and control of animals, almost similarly to how Daenerys is with Drogon. Each Stark child (or bastard in this case) has that huge connection with their Direwolf, especially Jon and Ghost. How crazy would it be to see Jon become Ghost by realizing and using his warging abilities.
