Spoiler alert: If you haven't watched Game of Thrones Season 5 Episode 10 yet, know that it contains one of the most shocking moments in the history of the series (no mean feat) and it will be discussed in detail here.
Seriously, it's a doozy. Click that link and watch, if you haven't already.
Now, for the rest of us - we kinda feel like we should form a support group to help us cope with the stunning events of last night, but there's no time for that now. For now, all we can do is ask ourselves the big question of the day:
Could Jon Snow really be dead?
For once, we can't turn to George R.R. Martin's books for the answer, as Jon is left for dead at the end of the fifth and most recent book in GRRM's 7-part saga.
So we won't have any definitive answers regarding Jon's fate until Martin publishes his long (long) awaited sixth book, or until Game of Thrones Season 6 debuts in spring of 2016. (People are already making predictions about the premiere, because the Internet.)
But while the rest of us know nothing, one authority on Jon Snow is spilling the beans regarding the sad betrayal of the beloved Night's Watchman:
"I’ve been told I’m dead," actor Kit Harington said in a recent interview with Entertainment Weekly. "I’m dead. I’m not coming back next season. So that’s all I can tell you, really”
"Quite honestly, I have never been told the future of things in this show, but this is the one time I have. They sat me down and said, 'This is how it is.'”
He added that showrunners D.B. Weiss and David Benioff took him on a "Tony Soprano walk" to break the news, which is apparently a tradition for actors whose characters are getting "whacked" on HBO shows.
So yeah - it sounds like at the very least we won't be seeing much of Kit or Jon in season 6.
But if you really think the character who's been set up to play a major role in the finale from day one is actually gone for good, well...you know nothing (about), Jon Snow.
