"I blubbed my eyes out. I cried," Kit Harington said of reading the final Game of Thrones script

Kit Harington couldn’t keep his emotions in check after learning just how the story ends for Jon Snow in Game of Thrones.

The actor, 32, has played Snow for a decade now on the hit HBO series, meaning that when Thrones wrapped filming for its eighth and final season, things got emotional.

“I was very shocked and surprised at certain events unfolding,” Harington said Tuesday on The Late Show with Stephen Colbert of reading the final script. “And then I blubbed my eyes out. I cried. I cried, yeah.”

Harington said that of the entire cast, he was the last to learn just how the show, which is known for its twists and turns, ended — simply because he was too lazy to read the scripts.

“We had a table read and I was the one person who hadn’t read the episodes. Everyone else had them like, three days before and read them and I just … I think I told everyone it was because I didn’t want to know what happened but I think it was just laziness that I didn’t read them,” he explained.

“Anyway, I got to the table and they used me as a litmus test. [Creators David Benioff and D. B. Weiss] were looking at me to see how the events unfolded, and they got some pretty good reactions,” he said, adding that they caught his reactions on camera.

The British star also made it clear that his wife and former costar Rose Leslie will remain in the dark regarding the finale, as she urged him to spoil the season 7 finale for her, only to regret it later.

“She’s guessed, she has guessed every single possible outcome bar the one that happens,” he joked.

Harington and Leslie, who played Ygritte, met on set and married in June.

Season 8, which is made up of six episodes, will premiere April 14.

Harington previously told GQ Australia in January that filming those six episodes over 10 months was extremely intense, to the point where he and the rest of the cast and crew were “broken at the end.”

“I don’t know if we were crying because we were said it was ending or if we were crying because it was so f-ing tiring. We were sleep deprived,” he said. “It was like it was designed to make you think, ‘Right, I’m f—ing sick of this.’ I remember everyone walking around towards the end going, ‘I’ve had enough now. I love this, it’s been the best thing in my life, I’ll miss it one day — but I’m done.’ ”

HBO released the official season 8 trailer on Tuesday, which teased Jon Snow and Dany walking toward waiting dragons, Cersei at the Red Keep and Arya running from unseen pursuers, among other things.
