Jorah has been one of the "Game of Thrones" characters that viewers has seen over the past seasons of the show. The character, portrayed by Iain Glenn, was last spotted in episode 5 of Season 6 where he revealed his illness to Daenerys (Emilia Clarke). He was then ordered to go on a journey to find a cure for Greyscale.

Speculations posted by Reddit user HouseHeisenb3rd indicated that one woman may hold the key to Jorah's medical journey, TV Guide reported. The mysterious woman Quaithe may know of a way to cure Jorah. Avid fans may recall that Jorah met Quaithe when he journeyed to Qarth in Season 2 of the HBO series.

In the said scene, Quaithe can be seen painting a protection spell on the back of a man who was headed to Old Valyria. The area past the ruined city has been inhabited by Stone Men and a place where Greyscale tends to thrive. It was in Old Valyria that Jorah contracted the disease during a battle with the Stone Men in Season 5.

Meanwhile, Quaithe, who wore a face mask that consisted of several hexagonal pieces, gave Jorah the information he needed to find Daenerys' dragons during their initial meeting. The masked woman also told the now Greyscale-diseased warrior that she knew of his love for Queen of the Dragons. With her knowledge of a magical protection spell, she may also know how to cure Jorah, as stated in the same report.

In other news, Glenn was recently spotted heading to the HBO series' filming location in Belfast. A Twitter user has recently posted a message on the said social media site that revealed actor, as well as cast member Gwendoline Christie (who plays Brienne) on board a flight heading to Belfast, Winter is Coming reported.

The actor was even seen holding a script during the said Belfast flight. However, it was unclear if the script was for the HBO series or for another acting project.

"Game of Thrones" Season 7 is expected to return to the small screens in summer 2017.
