Do you think that Jorah Mormont ever regrets taking a shortcut through the ruins of Valyria? Ever since Game of Thrones‘ fifth season, Jorah has been troubled by a skin care problem that neither the maesters of the Citadel nor the finest dermatologists in Beverly Hills can handle. However, last night’s stomach churning greyscale scene could potentially change the game going forward. Today’s Nerdist News is biting down on the belt and sharing secrets straight outta Oldtown!

There are potential spoilers ahead, as well as spoilers for last night’s episode of Game of Thrones. We’re not saying that you’ll want to cut off your own arm after hearing the latest GoT theories, but why take the chance?

Join host and breaker of chains, Jessica Chobot, as she peels back the layers of Jorah’s greyscale removal. And we certainly hope you weren’t eating when you saw that scene play out last night! You may have noticed that the series is giving a lot of screen time to Jorah’s search for a cure, and we don’t think it’s a coincidence. Somehow, greyscale is going to become important to the overall story, and we believe we know how.

According to the lore of A Song of Ice and Fire, greyscale is known as “Garin’s curse,” and it was a plague that placed on the Valyrian army. If it originated in Valyrian, it may also have properties that could be useful in the war against the White Walkers. An extreme theory has suggested that Daenerys and Jon Snow could potentially use or threaten to use greyscale against their mutual enemy, Queen Cersei. But even for this show, that seems very unheroic.

Another possibility is that the cure for greyscale could lead to significant scientific advances that could shift the power back from magic to reason. Remember, magic was thought to be dead in this world until the three dragons were born. Last night’s episode also put a lot of time into suggesting that the dragons can be killed.

Finally, and this is a wild one, the last theory is that residents of Westeros could be inoculated against becoming a wight if they are exposed to the virus and cured almost immediately afterwards. In the Night’s King can’t add any more members to his ever-growing army of the undead, then perhaps the realm has a shot.

What do you think about our greyscale theories? Let’s discuss in the comment section below!
