You know nothing.
Jon Snow lives! At least, according to Kit Harington's interview with Humo, a Belgian magazine.
In the interview, Kit talked about how long he's still under contract with the HBO show. A Reddit user translated his interview with the magazine, and while Kit wouldn't give away how long exactly, he did say, "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."
Kit is currently 28 years old, and he's turning 29 in December, so it looks like he still has at least a year or so on Game of Thrones.
While Kit has been seen on set filming for season 6 the show, this is the first time we've heard it straight from him that he'll continue to be on the show.
