  ====Season 7====
  Jorah returns to Westeros, seeking aid at the Citadel in Oldtown. By this time his greyscale has drastically progressed, consuming his entire arm and part of his torso. Archmaester Ebrose diagnoses Jorah's greyscale as untreatably advanced, and informs Jorah that he has six months of sanity left and will be exiled from the Citadel the next day. Samwell Tarly, who formerly served under Jeor in the Night's Watch, rediscovers a cure for greyscale. Despite being forbidden to administer it, because whoever treats the patient could become infected, he treats Jorah in secret and successfully heals Jorah's greyscale. Ebrose, although unimpressed by Jorah's attempts to conceal Sam's treatment, discharges Jorah. Jorah then returns to Daenerys, who is happy to see him and accepts him into her service once again. He then joins the expedition led by Jon Snow beyond the Wall to capture a wight and prove its existence to Cersei Lannister. He and Jon talk about their respective fathers, and Jon expresses his relief that Jorah was not executed. Jon attempts to return Longclaw to Jorah, on the basis that it is still the family sword of House Mormont, but Jorah refuses, claiming that he forfeited his right to claim the sword and that Jeor ''gave'' the weapon to Jon, making it his. Jorah survives the expedition and returns to Dragonstone.
