But, some fans believe Sam may have already stumbled upon the cure for greyscale — the Tarly just doesn’t realise it quite yet.
They believe that, on the page next to where Sam sees the Dragonglass location during the season premiere, there are notes about the healing powers of Dragonglass.
While the action was happening at sea, Samwell Tarly was attempting to cure Ser Jorah’s greyscale, removing the infected areas using a surgical knife (and leading to one of the show’s most horrible scenes).
Could Ser Jorah eventually be transported to Dragonstone to be cured?
