In July 2016, a full year before seven seven was aired, redragebar posted the following on the Game of Thrones subreddit. “Sam leaves for the Ruins of Valyria to search for information about the creation [of] Valyrian steel. He read about the Doom of Valyria and in the process finds the cure for Greyscale… He meets Jorah, not quite fully consumed yet, and helps to cure him.”
And although the order and location of those events wasn’t quite right – Sam met Jorah at the Citadel, not at the ruins of Valyria, and it took him less than an episode to locate a greyscale cure – redragebar was pretty much on the money. Sam is indeed helping to cure Jorah. But now that we’ve already seen the aforementioned cure being performed in wince-worthy detail on screen, what could happen next?
