Jorah's greyscale surely must catch up with him during Season 6. I'd place a wager the size of Essos that he won't survive the season. He can't. If contracting an incurable disease wasn't already bad enough for Jorah, he's trekking to find the Mother Of Dragons with the man she's sleeping with. It's going to be the Mother Of All Awkward Journeys as the pair roam the land not knowing whether they will find their Queen. Lord Friendzone and Friendzone 2.0 aren't going to have a fun ride, and if that doesn't result in Jorah taking a fatal blade, the greyscale will creep up and finish him anyway.
