We finally know that Jon Snow is not, in fact, Ned Stark’s son. But when will he find out?

During a Game of Thrones panel at San Diego Comic-Con Friday actor Isaac Hempstead Wright, who plays Bran, predicted that his newfound knowledge about Jon’s parentage might not go over so well with the King of the North.

“Bran knows he’s been shown this information for a reason, he might not know exactly why, but it’s obviously imperative he knows this and will spread the word,” the actor said. He said he thinks the conversation with Jon might go something like this: “By the way, I’m a tree wizard, and your dad isn’t your dad.”
