Ser Jorah currently has the biggest and most shiny Dead Meat badge in the whole of Westeros thanks to his unwanted close flirtation with a stone man and the nasty results. Yes, that was an STD pun. The poor disgraced knight has had a tough time of it recently, having fallen out of favour with the Mother Of Dragons, but once more showing that he's a good egg and that her life means everything to him, he's back on the rise up the ladder. Unfortunately, being in Dany's good graces isn't a known cure for zombie stone disease. How He'll Die Faced with the indignity of dying from Greyscale, you have to suspect that Jorah will go down in battle fighting to continue proving to Danaerys that he's her lobster, or something. Despite his infection being curable, Jorah is too far away from the best medics in the land for the necessary treatment, and he already seems resolved that his time is coming to an end (hence his reckless ignorance of Dany's demands for exile). You probably shouldn't write off him dying slowly and in lots of pain either, just for some more emotional impact.
