When you’re an actor on a show, chances are you know all the behind-the-scenes secrets—including, quite possibly, how the series will end. But when you’re an actor on Game of Thrones, the secrecy is much more intense, and even the show's biggest stars don't always know everything.

So when you're an actor on Game of Thrones whose character was killed off a few seasons back, it's safe to steal a line from Ygritte and say: "You know nothing, Jon Snow." Or, in the case of Richard Madden: "You know nothing, Robb Stark."

Though Madden played Robb Stark for three seasons until his untimely (and very memorable) death at the Red Wedding, we're pretty sure the 32-year-old actor is as clueless as the rest of us when it comes to how the final season will shake out. Still, Madden—who just earned a Golden Globe nomination for his work on Netflix's Bodyguard, and who is being loudly talked about as the next James Bond—had a pretty bold prediction about the series' finale. Speaking to The Hollywood Reporter, Madden admitted that he doesn’t think any of his former co-stars will make it out of Game of Thrones alive.

"I kind of think it’s just going to be three dragons flying around and everyone else is dead," he said. "It’s a possibility!"

We certainly can't rule it out. And given Madden's own bloody demise on the series, one can't blame him for having such a dark theory. Yet he also shared how leaving the show was a blessing in that it allowed him to become a fan.

"I can’t wait for the new season," he said. "I kind of don’t recognize that I was in it anymore because I’ve been watching so many years of it, and they talk about Robb Stark and I know who he is but I don’t see myself in that role. I’m just a viewer now, which is so good. That was one of the bad things about being in the show is you got the scripts, so you knew what was going to happen next ... I’ve not had that for years, so now I can just truly enjoy it as a viewer, which is thrilling."

Game of Thrones will return to HBO for its final season in April 2019. In the meantime, we'll just keep our fingers crossed that Madden's prediction is just a random guess.
