Are you in the mood for some spoilers? I could whip some up right now.
At this point, it would end up being a really interesting twist if Jon Snow was actually dead. No one would see it coming if it was revealed that what really happened when Jon Snow was killed onscreen was that he died. The most shocking thing that could happen in season six is if they buried him, mourned him, and never saw him again, whether in human, dire wolf, White Walker, or Azor Ahai form. Characters would miss him, but eventually, they move on.
But no, as we all accept by now, Jon Snow is alive AF. And poor Kit Harrington has become a highly empathetic figure for not being allowed to say anything about it or change his hairdo. The most recent evidence in the case for Jon Snow being alive comes from an interview with Harrington in Belgian magazine Humo, which was then translated by someone on Reddit:
“…I had to pass on amazing parts because I was attached to Game of Thrones. So the show is like a double-edged sword to me: I owe a lot to it, but at the same time it has almost completely drained me. Oh well, I try not to think about it too much. The important thing is that I now know exactly how long I am still under contract, and in the meantime –”
How many more seasons would that be?
“Nice try [laughs]. I can’t talk about that. Let’s just say that Game of Thrones will remain a part of my life for a while, I’ll probably be in my 30s when it’s over. One thing’s for sure: the day I’m no longer on Thrones is the day I’ll bury myself in movie projects [laughs].”
So, Harrington is clearly implying that he is still under contract with Game Of Thrones for multiple years. That means Jon Snow is either alive or about to begin an extensive multi-year flashback journey. Which sounds crazy until you think of all the Jon Snow-Ygritte scenes you'd still like to see.
