Okay, so the cure for greyscale is completely disgusting. But, it’s also surprisingly easy, considering how fearsome and terrible the disease apparently is. Indeed, only one other person in the show has ever come away from greyscale alive – Stannis’s daughter Shireen, who ended up being murdered by her father before anyone had much of a chance to study her. So will Sam, too, end up a greyscale fatality? Or is this all a set-up for a future plot?
Well, one Redditor, redragebar, thinks they have the answer. And actually, they might have had the answer before series seven even started. The Thrones fan noted the oft-repeated point in the show that Valyrian Steel is one of the only things that can kill White Walkers. Plus, we know that Valryia holds the secret to its making, but is currently overrun by the zombie-like grayscale-engulfed “Stone Men.” With this in mind, then, redragebar came up with a theory.
