(Warning - the following contains LARGE, HULKING POTENTIAL SPOILERS for Game of Thrones season 6, particularly as it relates to Jon Snow. Proceed with whatever level of caution your innate SPOILER-aversion dictates...)
Now, with filming very much underway on Season 6 of HBO's wildly popular Game of Thrones, it's not all that surprising that we're all already completely obsessed with what we're set to see onscreen come 2016. A big part of that growing preoccupation, however, has an awful lot to do with a certain character's potential return, and just how that could happen. Y'see:
It Sure Does Look Like Jon Snow Will Be Back in Season 6
Which, sure, the show's higher ups have repeatedly assured us is a very permanent thing - with HBO executive Michael Lombardo noting:
"Dead is dead is dead. He be dead."
...Kit Harington, who plays Jon, sure does keep getting spotted taking part in major battle sequences on the Game of Thrones set - which would seem to suggest he isn't quite as dead as we've been told.
If Harington really is set to return for Season 6, though, then:
How Could Jon Snow Actually Return?
We did, after all, last see him bleeding out in the snow, having just been stabbed repeatedly by his comrades in the Night's Watch. How's he going to come back from that in a show where medical standards aren't (what any sane person would call) great?
Well, let's take a look at three of the leading theories...
3. He's Not Actually Dead
Now, sure, we may have seen Jon Snow get repeatedly stabbed, and then watched - most likely while screaming and/or covering our eyes - as he seemed to begin the slow, painful process of bleeding out all over Castle Black's courtyard.
But that doesn't necessarily mean that he's dead.
After all, there's a pretty solid rule in the Game of Thrones universe that if you don't watch someone's head get removed or their throat slit, there's a decent chance they're still alive.
Come Season 6, then, could we find Jon Snow recovering nicely in the caring arms of a newly-arrived Davos Seaworth or Lady Melisandre? It's certainly possible...
2. He's Going to Become a White Walker
Now, this one's a long shot - especially seeing as in every glimpse of Snow we've had thus far, he doesn't really seem to be a pale white killing machine determined to destroy the realms of men, but it's not completely out of the realms of possibility, either.
After all, if his erstwhile colleagues in the Night's Watch were to neglect to burn him - which, what with Alliser Thorne having the listening and advice-taking skills of a deaf turtle, isn't entirely unlikely - then Jon could well find himself transformed into that which he so staunchly opposed.
Perhaps with a surprisingly still human-looking twist...
The most likely option, though?
1. He's Going to Be Resurrected by the Red Woman
Yup, that's right. Remember how Thoros of Myr - a red priest, much like Melisandre - was able to resurrect Beric Dondarrion a whole bunch of times?
Well, there's every reason to believe that Melisandre is able to pull off much the same kind of trick - which, seeing as she seemed to take a distinct interest in Jon and his future during Season 5, and just so happens to be in the area of his murder, might well be the most obvious solution to this particular problem.
After all, that way, Jon would indeed be dead - solving both the problem of senior HBO execs saying he is and his lifelong Night's Watch vows - but then be resurrected, leaving him able to reclaim the Stark name and fight on...as Jon Stark.
In exchange for which, Melisandre will presumably only require complete and utter devotion to the Red God in perpetuity. Which has never caused anyone any problems before...
