Jon Snow knows everything now and the world will never be the same.

Well, it seems like the last season of 'Game Of Thrones' show will be a rollercoaster of emotions, not just for the fans, but even the actors.

Kit Harington, who has been playing the role of Jon Snow since the beginning of the show, revealed on BBC's The One Show that he started crying when he, along with all the other cast members, sat down for a read through of the final episode of the insanely popular HBO show.

“We had a read through last week in fact, so I know everything now,” he said. “I cried at the end! You have to remember, I've done eight years of it... I get a bit weepy thinking about it.”

Even though the final season will come out in 2019, just the thought of its inevitable end has everyone quite emotional, even now. The actor admitted that just the thought of it ending seems very strange to him, especially after he has given the show his everything for the last eight years.

“I get a bit weepy thinking about it. It's going to be to a strange year. Saying goodbye to everyone, having your last scene with this person or having your last scene with that person. Not only you're attached to it, loads of people around the world are attached to it,” Harington said.

Obviously, he knows his character's fate, but he has been 'sworn to secrecy'. In fact, the makers are going to unbelievable lengths to keep all the twists and turns that are about to happen in the season finale of the show under wraps.

“[I was told], 'Don't tell them you're filming. Don't take pictures in Belfast. Don't do all of that,'” he said. “It's on lockdown!”

Although, the fact that his time in Westeros coming to an end is making him a little “weepy” right now, he has previously admitted that he was pleased to be finishing his run on the show, as it will give him the time to pursue other projects.

But, he can't escape Jon Snow, and he probably never will. Just recently, his fiancé Rose Leslie made him dress up as Snow for a “bad taste” costume party.

Well, even though Kit now knows everything, we will still, unfortunately, have to wait two years for the finale.

Also, this meme is a lie now.
