Sophie Turner already revealed the Game of Thrones ending to a few friends

W Magazine

"I’ve already told the ending of Game of Thrones to a few people," Turner admitted to W magazine. Asked if she was drunk, Turner responded: "Nope, sober. I was like, 'Hey, if you want to know, I’ll tell you.' But it’s people that I know, not random people. It’s people that I know will keep the secret."
